The Turkish Lira: Monetary History, Crises of Confidence and the Numbers Behind Them
When more lira are needed to buy a dollar, the implications extend to wages, imports, savings and contracts denominated in foreign currency. Yet the exchange rate on a screen cannot explain the whole story. The old lira, with its amounts in millions, used a different unit of account from the currency introduced in 2005. A full-year average differs from a single day's rate, and falling inflation differs from falling prices. This guide traces the story from the early Republic to the information available on 11 October 2026, connecting historical turning points with economic mechanisms and clear worked examples.
The approach is historical and explanatory: each release is dated, and calculations based on assumptions are identified as examples. Past trends are not promises of future exchange rates, and an interest rate alone cannot establish whether a financial asset is suitable for an individual.
The Republic did not introduce new banknotes on the day it was proclaimed. Paper currency inherited from the Ottoman Empire remained in legal circulation until 1927, when the Republic's first banknote series entered circulation on 5 December. Printed by De La Rue in England, the notes used Ottoman script because they predated the alphabet reform. The replacement legislation, Law No. 701, had entered into force on 30 December 1925. Thus, referring to the lira “since 1923” identifies the start of the republican period; it does not mean that banknotes bearing the new Republic's identity were all issued that year.
The idea of a national monetary institution preceded the central bank itself. The İzmir Economic Congress discussed establishing a national state bank in 1923. Central Bank Law No. 1715 was adopted on 11 June 1930, and the Bank began operations on 3 October 1931. These dates mark three distinct stages: the institutional concept, its legal framework and the start of operations. Collapsing them into a single date obscures the development of monetary policy.
It is useful from the outset to distinguish the currency as a unit of account, banknotes as one means of using it, and the central bank as the institution responsible for monetary instruments. A banknote redesign may mark a political or technical transition, but it says nothing about how many goods the note can buy. Nor does a currency's age guarantee a stable value. Its domestic value is measured against prices, while its external value is measured against other currencies, and the two may change at different rates. Understanding the lira therefore requires institutional history alongside price and exchange-rate data, rather than banknote images or a count of the zeros printed on them.
The central bank's history records that the general price level more than tripled between 1938 and 1948 amid the effects of war and policies used to finance deficits. Law No. 1211, adopted on 14 January 1970, subsequently reorganised the Bank. In 1980, the decisions of 24 January began a shift towards market mechanisms and financial and trade liberalisation. Decree No. 32 in 1989 permitted foreign-exchange transactions alongside currency convertibility and a more flexible exchange-rate regime.
These milestones show how the framework in which the lira operates has changed. Under restrictions, currency pressure may appear as difficulty obtaining foreign exchange or as administrative measures. In a more open system, it can emerge more quickly in market prices and capital flows. Currency declines in different decades should therefore not be interpreted through an identical institutional mechanism, nor should every change be called a “float” without defining the term.
Government and bank funding, together with the economy's links to the rest of the world, are also part of the story. When foreign-currency liabilities grow while revenues remain concentrated in lira, balance sheets become more sensitive to exchange-rate changes. Reliance on short-term funding makes the ability to refinance during periods of stress especially important. This explains a general economic risk; it does not imply that every episode of liberalisation causes a crisis. Openness also supports trade and financing, while institutions, obligations and confidence shape the response to volatility.
These earlier reforms must be distinguished from the specific turning point in February 2001. A “more flexible regime” is not automatically the same as the free float adopted during that year's crisis.
The central bank dates the financial crisis to the first quarter of 1994, linking it to financial-sector pressures, political instability, fiscal loosening and fragile banks. Its reports confirm that the 5 April stabilisation programme followed the crisis earlier that year and included stringent measures to reduce the public-sector deficit. This is more precise than reducing the episode to a single day or citing a percentage collapse without identifying its source and measurement period.
To understand how these elements interact, consider an economy in which the government and banks need continuous financing. Confidence in their ability to repay and refinance becomes as important as the size of their obligations. As concern grows, lenders may demand higher returns or decline to roll over funding, while savers may move into foreign currency. These pressures can reinforce one another: higher financing costs strain balance sheets, a weaker currency increases the cost of foreign-currency obligations, and deteriorating balance sheets deepen concern.
This process does not justify treating every crisis-driven rise in interest rates as successful anti-inflation tightening. High rates can include a premium for fear and risk, whereas price stability requires a framework whose continuity people can trust. A stabilisation programme must therefore be read through public finances, liquidity, banks and expectations together.
Another pitfall in the 1994 archives is that lira figures use the old unit. Tens of thousands of lira per dollar in a historical table cannot be compared directly with tens of lira in 2026. First put both observations on the same unit basis, then establish the rate type and measurement dates. Where a precise decline cannot be established from a primary source, confirmed milestones are more useful than a widely repeated but undefined percentage.
The 2000 stabilisation programme was exchange-rate based. Confidence weakened towards the end of that year, and the crisis intensified in 2001. The central bank's annual report records political tension and market panic on 19 February, followed by liquidity pressures and bank funding difficulties over the next two days. On 22 February 2001, the lira moved to a floating exchange-rate regime after the previous framework could no longer be sustained. The date matters because it changes how subsequent movements are interpreted: the rate reflected market pricing under a float, rather than the earlier commitment to a specified exchange-rate path.
A floating rate does not mean that the central bank disappears from the market or that policy ceases to matter. Interest rates, liquidity, reserves and communication still influence outcomes, and interventions or financial operations may take place. What changes is the nature of the commitment to maintaining a particular exchange-rate level. Distinguishing the regimes also helps explain the difference between an official devaluation and market-driven depreciation.
An institutional amendment adopted on 25 April 2001 and published on 5 May established price stability, independence in choosing policy instruments and a prohibition on direct Treasury financing within the law. The Bank then pursued implicit inflation targeting between 2002 and 2005, followed by explicit targeting in 2006. These dates show why the response to the crisis extended beyond the exchange-rate adjustment to banks, policy and institutions.
Milestones for understanding the currency unit and regime
Law No. 5083 was adopted on 28 January 2004, and the new unit took effect on 1 January 2005: one million old lira equalled one New Turkish Lira, divided into 100 New Kuruş. References to lira in transactions and documents were subject to the same conversion ratio. Both currencies circulated during 2005, with prices displayed in both units; the old currency was withdrawn from circulation in January 2006.
The arithmetic is straightforward: divide amounts by one million while preserving their relationships. If the numerical amounts of a salary and a product's price both fall by the same factor, the salary still buys the same number of products. Accounting, price labels and transactions use smaller numbers, but division does not increase society's resources or output, nor does it automatically increase the currency's ability to buy dollars.
A hypothetical redenomination example, not historical wage data
Currency reform may coincide with improving inflation and credibility, but that context must be distinguished from the arithmetic effect of conversion. Saying that removing zeros “made the lira a million times stronger” confuses the number of units with their value. Conversely, subsequent inflation does not prove that simplifying the numbers had no accounting benefit: that administrative function differs from the task of stabilising prices.
This distinction matters in historical comparisons. The end-2004 dollar buying rate of 1,342,100 old lira equals 1.3421 in the post-2005 unit. Comparing the unadjusted figure with a small number after the reform suggests an illusory jump, which disappears when the units are aligned. Any difference between two year-end rates after that conversion remains an economic change requiring a separate explanation.
The removal of Yeni, meaning “New”, was based on Council of Ministers Decision No. 2007/11963 of 4 April 2007, effective from 1 January 2009. E9 banknotes entered circulation and circulated alongside E8 notes during 2009. This was a change in name and banknote issue, not another million-to-one conversion. For comparison purposes, the New Turkish Lira introduced in 2005 and the Turkish lira without “New” after 2009 use the same scale of value.
Data from 2010 onwards can therefore be read directly in the current lira unit, while paying attention to the details of the series. The currency name alone does not reveal whether a figure is a buying or selling rate, an annual average or a year-end observation. Two series may look different and still both be correct because they measure different things.
This also helps when reading an old document or a report quoting the “dollar against the New Turkish Lira”. Establish the document's year and unit of measurement, then convert amounts where necessary, without changing an obligation's value merely because the name changed. Images of different banknote issues cannot, on their own, establish the exchange-rate path or inflation level.
To examine the following decade, we use a consistent annual series to identify the long-term trend, then return to policy and crisis dates to understand what averages conceal. An average summarises a year and reduces the influence of any one day's volatility, but may mask a sharp movement in its final months.
The table shows the annual average lira price of one US dollar using the OECD series published through FRED. Each observation averages daily rates over a full year; it is neither the 1 January rate nor the end-December rate. The final column calculates the change from the previous year's average. It therefore describes a change in the annual average level, not necessarily the outcome for someone who bought currency on one date and sold it on another.
Annual averages: Turkish lira per US dollar
Figures are displayed to four decimal places, and percentage changes were calculated from the underlying values before rounding. There is no annual observation for 2026 because the year was incomplete when this guide was prepared. The 9 October rate discussed later is a separate daily observation, not a directly comparable continuation of this annual table.
The series shows a sustained increase in lira per dollar, but does not establish a single cause for every year. The 2021 average also conceals differences between months, while the 2022 average may reflect the persistence of high rates reached earlier. The table should therefore be read alongside the sequence of policies and shocks, without mistaking an observation's database date label for a transaction date.
One mathematical distinction is crucial: a rise in the dollar's lira price does not translate into an equal percentage fall in the lira's dollar value. The relationship is reciprocal. If the dollar's local-currency price doubles, the lira loses half its dollar value, not all of it. We apply this distinction to specific historical observations below.
In its retrospective assessment, the International Monetary Fund linked the lira's weakness to domestic and external imbalances: an economy operating above estimated capacity, high inflation, a debt-financed external deficit and private-sector currency mismatches between revenues and liabilities. These vulnerabilities were then exposed to worsening sentiment towards emerging markets and geopolitical developments. The central point is that the shock hit already-sensitive balance sheets; a single political news event cannot explain the entire episode.
On 13 September 2018, the central bank raised the one-week repo rate from 17.75% to 24%, an increase of 625 basis points, or 6.25 percentage points. Inflation reached about 25% in October, according to the IMF's assessment. These figures refer to particular periods and should not be presented as if they all occurred on the same day.
The official dollar buying rate was 3.7719 lira in the 2017 year-end comparison and 5.2609 on 31 December 2018. Between these observations, the dollar's lira cost rose by about 39.48%, while the lira's dollar value fell by about 28.30%. This compares two year-end points; it is neither the crisis's largest movement nor the 2018 annual average shown earlier.
Consider a company that earns lira revenues but pays dollar liabilities: it needs more lira to meet those payments before it can adjust prices or increase revenue. The outcome differs if it has dollar export revenues, hedging arrangements or different payment dates. Exchange-rate changes therefore do not affect every company or household uniformly; their impact depends on the currencies of income and obligations and the timing of settlement.
The Bank held its policy rate at 24% during the first half of 2019, then reduced it to 12% through meetings in the second half. Its report attributed disinflation to several factors, including lira stability, fading exchange-rate effects, weak demand and import prices. Inflation can therefore fall through more than one channel; the change should not be attributed solely to interest rates.
The pandemic then changed trade, tourism and demand conditions in 2020. The annual report describes weak activity at the outset, followed by credit expansion as conditions normalised, and also links rising inflation to lira depreciation. In November, the rate rose from 10.25% to 15%, then to 17% in December. Describing the whole year simply as a period of “hikes” or “cuts” omits the change of direction within it.
A shock of this kind affects both demand and supply. Companies may face weaker sales while finding inputs harder to obtain or shipments delayed. Lower external services revenue can reduce foreign-currency inflows, while import demand may also change. Neither the claim that recessions always lower prices nor the idea that credit expansion explains all inflation is sufficient during such disruption.
This is why crisis analysis requires monthly data, with annual averages retained as a way to summarise the trend. The 2020 average combines contrasting conditions; it neither describes the market in November alone nor measures the direct effect of a particular decision.
The Bank raised its rate from 17% to 19% in March 2021, held it unchanged from April to August, then cut it by a total of five percentage points between September and December to 14%. Its rationale at the time included an assessment that supply pressures were transitory. Here we record the historical decision and its stated rationale without treating that rationale as an established fact about every component of inflation. Consumer inflation ended the year at 36.08%.
These conditions saw the introduction of exchange-rate-protected deposit arrangements, known as KKM. On 21 December, the central bank announced a facility for converting existing foreign-currency deposits into lira term deposits. At maturity, it compared interest or profit payments with the exchange-rate change. If the exchange-rate-adjusted value exceeded principal plus interest, the central bank covered the difference under the facility described in that announcement. This does not mean that all historical versions of the programme shared the same funding institution or terms.
The programme illustrates the distinction between choosing a deposit's currency denomination and allocating currency risk. An account can be denominated in lira while carrying conditional protection linked to exchange rates. A larger share of such accounts does not, by itself, establish that sensitivity to the dollar has disappeared from depositors' expectations or from the obligations of the institution covering the difference.
Protection against exchange-rate movements is also not full protection against domestic inflation. Price changes can erode purchasing power even when protection under another benchmark is delivered. The original announcement made the benefit conditional on reaching maturity; early withdrawal was not treated in the same way. KKM should therefore be understood as a historical instrument with specific terms and periods, rather than a general guarantee suitable for every saver in every year.
The Bank's 2022 report linked import and price pressures to global energy and commodities, the effects of Russia's war in Ukraine and transport costs, alongside the impact of lira depreciation in late 2021. The Bank continued cutting rates from 14% to 9% between August and November. Annual inflation reached 85.51% in October, then 64.27% in December.
To understand overlapping shocks, the lira cost of an imported input equals its foreign-currency price multiplied by the exchange rate, before transport, duties and distribution are added. If the world price rises while the lira weakens, the two effects compound. The entire increase cannot then be attributed solely to global prices or solely to the currency. Imported inputs can also raise the cost of locally manufactured goods, transmitting the shock to products consumers may not regard as imports.
This period illustrates a common misunderstanding: inflation falling from 85.51% to 64.27% does not mean prices fell by the same amount or returned to their old level. It means the annual rate of increase slowed while remaining positive. The rate can also change because it is being measured against a high base in the previous year.
The distinction matters for households and businesses. Lower inflation may improve planning, but it does not automatically restore the previous purchasing power of a salary that failed to keep pace with prices. Nor does it, on its own, reduce replacement inventory costs to the cost of older stock. Price levels and income should be tracked alongside rates of change, rather than one being substituted for another.
On 22 June 2023, the Bank announced the start of monetary tightening and raised the repo rate from 8.5% to 15%. The rate reached 42.5% in December, 45% in January 2024 and 50% in March. At the end of December 2024, it was reduced to 47.5%. This is the path of a particular policy instrument; it does not automatically describe every market lending or deposit rate.
Selected one-week repo decisions, not annual averages
Interest rates work through financing costs, demand, credit, asset choices and expectations, but their effects take time and vary between participants. Services prices and contracts adjusted periodically may respond slowly, while market indicators can change much faster. One month after a rate hike is therefore insufficient to judge its full effects, just as high inflation does not prove that tightening had no effect at all.
Annual inflation reached 75.45% in May 2024, then 44.38% in December. The fact that inflation peaked after rates had risen is a reminder that policy decisions also respond to inflation and risk. The relationship is not a simple experiment in which one factor changes while everything else remains constant.
A balanced reading separates what was announced, what happened and the explanation for that outcome. The announced rate is a dated fact; the change in inflation is another. Establishing each instrument's contribution requires more than comparing two numbers. Subsequent nominal rate cuts can also coexist with restrictive financial conditions if expectations, liquidity and credit constraints change.
The 2025 cycle was not an uninterrupted sequence of cuts. After reductions brought the repo rate to 42.5% in March, the Bank raised it to 46% on 17 April. Cuts resumed in July to 43%, followed by 40.5% in September, 39.5% in October and 38% in December. These decisions show how policy can change direction within a year in response to financial and inflation risks.
In its assessment published in February 2026, the IMF recorded the turbulence of March 2025, with capital outflows, lira weakness and reserve losses, alongside a broader improvement in demand for lira during the stabilisation period. That assessment should not be read as a description of conditions in October 2026: its information window and publication date are different. Causal analysis also requires separating the annual trend from an episode of pressure within it.
On 23 August 2025, the Bank terminated KKM account openings and renewals, excluding YUVAM accounts, while existing accounts remained valid until maturity. Saying that “openings and renewals ended” is more precise than saying all balances disappeared on the announcement date. A decision affecting new flows is different from the outstanding stock, a distinction that also matters in credit and deposit statistics.
The exit raises questions about how risk shifted: did lira savings become less dependent on exchange-rate compensation, and how did financing costs, deposit terms and confidence change? These questions require a sequence of data, rather than a programme name alone. Discontinuing an instrument does not automatically remove the reasons it was introduced or guarantee that everyone is protected against inflation and currency volatility.
In the latest decision available at this guide's preparation date, issued on 10 September 2026, the Bank held the one-week repo rate at 37%, the overnight lending rate at 40% and the overnight borrowing rate at 35.5%. September consumer inflation was 29.73% year on year and 1.84% month on month. The latest official exchange-rate observation displayed in the Bank's service at the review date was for 9 October and was an indicative rate.
Different periods and instruments: check the dates before comparing
The 40% figure needs particular care. The Inflation Report published on 13 August stated that one-week repo auctions had not been held since 2 March and that funding and sterilisation operations were conducted at the overnight lending rate, with a weighted average funding cost of 40% during the reporting period. The announced policy rate thus remained 37%, while the cost of implementation differed. The first figure should not be relabelled as 40%, nor should August's funding cost be presented as the latest daily cost on 11 October.
The “dollar buying rate” is also the buying side from the perspective of the institution quoting the rate; it does not mean every customer can buy dollars at that price. An indicative rate differs from a bank or exchange bureau's quote, and physical banknotes have separate rate columns. The daily observation cited here describes neither the end of 2026 nor its annual average.
Falling annual inflation alongside a monthly rise in the index is not a contradiction: prices may be rising this month more slowly than in the corresponding month a year earlier. Nor does the aggregate figure describe every household's experience, since food, housing and transport may have different weights in its budget from those in the statistical basket.
Exchange-rate movements affect prices directly through imported goods and indirectly through inputs and production costs. Pass-through is neither immediate nor a fixed percentage across all sectors: contracts, inventories, competition, margins and demand all matter. Exchange-rate pressures can therefore ease while some prices continue rising, or global energy prices can rise despite relative currency stability.
Nominal interest differs from real interest. For an illustrative comparison over a one-year horizon, the exact formula is: Real interest rate = [(1 + nominal interest rate) ÷ (1 + inflation) − 1] × 100, entering the rates as decimals. For a forward-looking decision, use expected inflation over the same horizon; when measuring a realised outcome, use actual inflation and the return for the matching period.
For example, a hypothetical annual interest rate of 40% with inflation of 30% produces a real rate of 7.69% before fees and taxes, rather than the 10% obtained by simple subtraction. Nor does subtracting 29.73% inflation from a 37% policy rate establish a saver's real return: one is past inflation and the other is the rate on a short-term policy instrument, not a guaranteed annual savings contract.
Definitions that prevent misleading conclusions
Reserves provide another example of why definitions matter. A rise in the dollar price of gold can increase the dollar value of reserves without the entire increase representing a new foreign-currency inflow. Gross holdings also differ from measures net of liabilities and swaps, depending on the definition used. Comparisons therefore require a common date and clearly specified components.
Confidence influences willingness to hold lira or refinance obligations, but it cannot be measured by a slogan or a single decision. Consistency in the policy framework, communication, price expectations and the fulfilment of obligations help explain it. Reading these elements together is more useful than assuming that the interest rate alone mechanically determines the exchange rate.
Let E denote the number of lira needed to buy one US dollar. When the rate moves from E0 to E1, the percentage increase in the dollar's lira cost is: (E1 ÷ E0 − 1) × 100. The percentage loss in the lira's dollar value, when E rises, is: (1 − E0 ÷ E1) × 100. The percentages differ because the denominator changes when the exchange-rate quotation is inverted.
If the dollar rises from a hypothetical 25 lira to 50, its lira cost increases by 100%, while one lira buys half as many dollars as before, a 50% loss in dollar value. A doubling of the dollar rate cannot be described as a 100% loss in the lira's value: that would mean its value had fallen to zero, which is mathematically different.
Specific comparisons: calculated percentages, not claims about the entire crisis
The 2000 and 2001 observations were converted from old lira by dividing by one million, as was the 2004 observation, so that the table consistently uses the post-2005 unit. The comparison between end-2004 and end-2005 spans a full year; it does not prove that removing zeros itself caused a 0.07% market movement. The figure describes two observations expressed in a common unit.
This loss against the dollar also differs from a loss of purchasing power against the Turkish consumer basket. Basket prices and income may change at different rates. Using the official buying rate keeps the calculation consistent, but does not account for actual transaction fees or the buying–selling spread a customer may face.
The following examples show why the measure must match the question. Start with a fixed TRY 100,000 and a dollar rate that moves from 40 to 50. The amount initially equals USD 2,500 and subsequently USD 2,000, a 20% decline in dollar value even though the dollar's lira cost rose by 25%. The number of lira is unchanged, but the comparison benchmark differs. This calculation alone says nothing about what TRY 100,000 can buy within Türkiye.
For an importer, a USD 1,000 input invoice at a rate of 40 costs TRY 40,000. If the foreign-currency price is unchanged and the dollar rises to 50, the cost becomes TRY 50,000. If the foreign-currency price also rises by 10%, the invoice becomes USD 1,100, or TRY 55,000. The combined increase is 37.5%: 1.10 × 1.25 − 1 = 0.375. Simply adding 10% and 25% gives 35% and misses the compounding effect.
Now suppose a property rises from TRY 5 million to TRY 6 million, a nominal increase of 20%, while the dollar rate moves from 40 to 50. Its dollar equivalent falls from USD 125,000 to USD 120,000, a 4% decline. In a separate calculation, assuming domestic inflation of 25% over the same period, its real price change is also minus 4%: 1.20 ÷ 1.25 − 1. The identical results here are a coincidence of the assumed figures; they do not make the dollar equivalent to the price index.
The example excludes rent, expenses, taxes, improvements and selling costs. It therefore measures only a price change, not a complete investment return. When cash flows are included, each flow's date and currency must be established. Converting flows from every period at one exchange rate and calling the result an actual return would be misleading.
Does lower inflation mean shops will cut prices? Not necessarily. A lower positive inflation rate means prices are rising more slowly. Some items may fall while others rise. The index level and its detailed changes determine the outcome, not the annual rate alone.
Do high interest rates guarantee a stronger lira? There is no guaranteed rule. Inflation expectations, risks, external flows, liquidity and timing all matter, and a decision may already be reflected in market prices. The rate alone is therefore insufficient to establish the outcome.
Did deposits stop being linked to the dollar as soon as KKM ended? The August 2025 decision concerns openings and renewals, with the stated exception and existing accounts running to maturity. Assessing balances and behaviour requires subsequent data and clear account definitions; it cannot be inferred from the decision alone.
Can the 9 October rate be used as the 2026 average? It is a specific daily observation of an indicative rate, different from a full-year average, a year-end rate or a customer's execution rate. The annual table above ends in 2025 to keep comparisons consistent.
What should be monitored to understand the trend?
Good monitoring starts with a specific question and a matching measure. To understand the cost of an imported product, separate its foreign-currency price from exchange rates and transport. To assess a salary, compare income with the relevant spending basket. To read an interest-rate decision, identify whether the announced rate changed or the method of funding and implementation changed.
A short record of dates, instruments and units helps prevent comparisons between a daily snapshot and an annual average, or between realised inflation and a future expectation. Where binding contracts, foreign-currency obligations or tax consequences are involved, applying the analysis requires a specialist who can examine the documents and circumstances; arithmetic alone does not settle legal or accounting details. Historical understanding shows how these mechanisms change and interact, giving readers tools to distinguish reliable information from hasty conclusions.
When more lira are needed to buy a dollar, the implications extend to wages, imports, savings and contracts denominated in foreign currency. Yet the exchange rate on a screen cannot explain the whole story. The old lira, with its amounts in millions, used a different unit of account from the currency introduced in 2005. A full-year average differs from a single day's rate, and falling inflation differs from falling prices. This guide traces the story from the early Republic to the information available on 11 October 2026, connecting historical turning points with economic mechanisms and clear worked examples.
The approach is historical and explanatory: each release is dated, and calculations based on assumptions are identified as examples. Past trends are not promises of future exchange rates, and an interest rate alone cannot establish whether a financial asset is suitable for an individual.
1. 1923–1931: The Lira in the Early Republic
The Republic did not introduce new banknotes on the day it was proclaimed. Paper currency inherited from the Ottoman Empire remained in legal circulation until 1927, when the Republic's first banknote series entered circulation on 5 December. Printed by De La Rue in England, the notes used Ottoman script because they predated the alphabet reform. The replacement legislation, Law No. 701, had entered into force on 30 December 1925. Thus, referring to the lira “since 1923” identifies the start of the republican period; it does not mean that banknotes bearing the new Republic's identity were all issued that year.
The idea of a national monetary institution preceded the central bank itself. The İzmir Economic Congress discussed establishing a national state bank in 1923. Central Bank Law No. 1715 was adopted on 11 June 1930, and the Bank began operations on 3 October 1931. These dates mark three distinct stages: the institutional concept, its legal framework and the start of operations. Collapsing them into a single date obscures the development of monetary policy.
It is useful from the outset to distinguish the currency as a unit of account, banknotes as one means of using it, and the central bank as the institution responsible for monetary instruments. A banknote redesign may mark a political or technical transition, but it says nothing about how many goods the note can buy. Nor does a currency's age guarantee a stable value. Its domestic value is measured against prices, while its external value is measured against other currencies, and the two may change at different rates. Understanding the lira therefore requires institutional history alongside price and exchange-rate data, rather than banknote images or a count of the zeros printed on them.
2. From the War Years to 1989: Inflation, Liberalisation and a Changing Framework
The central bank's history records that the general price level more than tripled between 1938 and 1948 amid the effects of war and policies used to finance deficits. Law No. 1211, adopted on 14 January 1970, subsequently reorganised the Bank. In 1980, the decisions of 24 January began a shift towards market mechanisms and financial and trade liberalisation. Decree No. 32 in 1989 permitted foreign-exchange transactions alongside currency convertibility and a more flexible exchange-rate regime.
These milestones show how the framework in which the lira operates has changed. Under restrictions, currency pressure may appear as difficulty obtaining foreign exchange or as administrative measures. In a more open system, it can emerge more quickly in market prices and capital flows. Currency declines in different decades should therefore not be interpreted through an identical institutional mechanism, nor should every change be called a “float” without defining the term.
Government and bank funding, together with the economy's links to the rest of the world, are also part of the story. When foreign-currency liabilities grow while revenues remain concentrated in lira, balance sheets become more sensitive to exchange-rate changes. Reliance on short-term funding makes the ability to refinance during periods of stress especially important. This explains a general economic risk; it does not imply that every episode of liberalisation causes a crisis. Openness also supports trade and financing, while institutions, obligations and confidence shape the response to volatility.
These earlier reforms must be distinguished from the specific turning point in February 2001. A “more flexible regime” is not automatically the same as the free float adopted during that year's crisis.
3. 1994: Financial Crisis and the 5 April Stabilisation Programme
The central bank dates the financial crisis to the first quarter of 1994, linking it to financial-sector pressures, political instability, fiscal loosening and fragile banks. Its reports confirm that the 5 April stabilisation programme followed the crisis earlier that year and included stringent measures to reduce the public-sector deficit. This is more precise than reducing the episode to a single day or citing a percentage collapse without identifying its source and measurement period.
To understand how these elements interact, consider an economy in which the government and banks need continuous financing. Confidence in their ability to repay and refinance becomes as important as the size of their obligations. As concern grows, lenders may demand higher returns or decline to roll over funding, while savers may move into foreign currency. These pressures can reinforce one another: higher financing costs strain balance sheets, a weaker currency increases the cost of foreign-currency obligations, and deteriorating balance sheets deepen concern.
This process does not justify treating every crisis-driven rise in interest rates as successful anti-inflation tightening. High rates can include a premium for fear and risk, whereas price stability requires a framework whose continuity people can trust. A stabilisation programme must therefore be read through public finances, liquidity, banks and expectations together.
Another pitfall in the 1994 archives is that lira figures use the old unit. Tens of thousands of lira per dollar in a historical table cannot be compared directly with tens of lira in 2026. First put both observations on the same unit basis, then establish the rate type and measurement dates. Where a precise decline cannot be established from a primary source, confirmed milestones are more useful than a widely repeated but undefined percentage.
4. 2000–2001: Why 22 February Was a Turning Point
The 2000 stabilisation programme was exchange-rate based. Confidence weakened towards the end of that year, and the crisis intensified in 2001. The central bank's annual report records political tension and market panic on 19 February, followed by liquidity pressures and bank funding difficulties over the next two days. On 22 February 2001, the lira moved to a floating exchange-rate regime after the previous framework could no longer be sustained. The date matters because it changes how subsequent movements are interpreted: the rate reflected market pricing under a float, rather than the earlier commitment to a specified exchange-rate path.
A floating rate does not mean that the central bank disappears from the market or that policy ceases to matter. Interest rates, liquidity, reserves and communication still influence outcomes, and interventions or financial operations may take place. What changes is the nature of the commitment to maintaining a particular exchange-rate level. Distinguishing the regimes also helps explain the difference between an official devaluation and market-driven depreciation.
An institutional amendment adopted on 25 April 2001 and published on 5 May established price stability, independence in choosing policy instruments and a prohibition on direct Treasury financing within the law. The Bank then pursued implicit inflation targeting between 2002 and 2005, followed by explicit targeting in 2006. These dates show why the response to the crisis extended beyond the exchange-rate adjustment to banks, policy and institutions.
Milestones for understanding the currency unit and regime
| Milestone | Established historical fact | What it does not establish on its own |
|---|---|---|
| 1927 | The Republic's first banknotes | Unchanged purchasing power |
| 1931 | The central bank begins operations | That creating the institution prevents every crisis |
| 1994 | Crisis and the 5 April programme | A percentage collapse without a defined period |
| 22 February 2001 | The currency begins floating | The absence of interest-rate or liquidity management |
| 1 January 2005 | One million old lira converted into one new lira | A millionfold increase in wealth |
| 1 January 2009 | Removal of the word “New” | Another removal of zeros |
5. 2005: Removing Six Zeros Without Creating Purchasing Power
Law No. 5083 was adopted on 28 January 2004, and the new unit took effect on 1 January 2005: one million old lira equalled one New Turkish Lira, divided into 100 New Kuruş. References to lira in transactions and documents were subject to the same conversion ratio. Both currencies circulated during 2005, with prices displayed in both units; the old currency was withdrawn from circulation in January 2006.
The arithmetic is straightforward: divide amounts by one million while preserving their relationships. If the numerical amounts of a salary and a product's price both fall by the same factor, the salary still buys the same number of products. Accounting, price labels and transactions use smaller numbers, but division does not increase society's resources or output, nor does it automatically increase the currency's ability to buy dollars.
A hypothetical redenomination example, not historical wage data
| Item | Old lira | New lira | Interpretation |
|---|---|---|---|
| Salary | 1,500,000,000 | 1,500 | Divided by one million |
| Product price | 3,000,000 | 3 | The same division |
| Units purchasable with the salary | 500 | 500 | Purchasing power is unchanged in this example |
| Hypothetical dollar rate | 1,500,000 | 1.5 | The same rate expressed in two units |
Currency reform may coincide with improving inflation and credibility, but that context must be distinguished from the arithmetic effect of conversion. Saying that removing zeros “made the lira a million times stronger” confuses the number of units with their value. Conversely, subsequent inflation does not prove that simplifying the numbers had no accounting benefit: that administrative function differs from the task of stabilising prices.
This distinction matters in historical comparisons. The end-2004 dollar buying rate of 1,342,100 old lira equals 1.3421 in the post-2005 unit. Comparing the unadjusted figure with a small number after the reform suggests an illusory jump, which disappears when the units are aligned. Any difference between two year-end rates after that conversion remains an economic change requiring a separate explanation.
6. 2009: Dropping “New” and Reading the Modern Data
The removal of Yeni, meaning “New”, was based on Council of Ministers Decision No. 2007/11963 of 4 April 2007, effective from 1 January 2009. E9 banknotes entered circulation and circulated alongside E8 notes during 2009. This was a change in name and banknote issue, not another million-to-one conversion. For comparison purposes, the New Turkish Lira introduced in 2005 and the Turkish lira without “New” after 2009 use the same scale of value.
Data from 2010 onwards can therefore be read directly in the current lira unit, while paying attention to the details of the series. The currency name alone does not reveal whether a figure is a buying or selling rate, an annual average or a year-end observation. Two series may look different and still both be correct because they measure different things.
This also helps when reading an old document or a report quoting the “dollar against the New Turkish Lira”. Establish the document's year and unit of measurement, then convert amounts where necessary, without changing an obligation's value merely because the name changed. Images of different banknote issues cannot, on their own, establish the exchange-rate path or inflation level.
To examine the following decade, we use a consistent annual series to identify the long-term trend, then return to policy and crisis dates to understand what averages conceal. An average summarises a year and reduces the influence of any one day's volatility, but may mask a sharp movement in its final months.
7. 2010–2025: What Annual Dollar-Rate Averages Show
The table shows the annual average lira price of one US dollar using the OECD series published through FRED. Each observation averages daily rates over a full year; it is neither the 1 January rate nor the end-December rate. The final column calculates the change from the previous year's average. It therefore describes a change in the annual average level, not necessarily the outcome for someone who bought currency on one date and sold it on another.
Annual averages: Turkish lira per US dollar
| Year | Average dollar rate | Change from the previous year's average |
|---|---|---|
| 2010 | 1.4990 | — |
| 2011 | 1.6717 | 11.52% |
| 2012 | 1.7916 | 7.18% |
| 2013 | 1.9045 | 6.30% |
| 2014 | 2.1890 | 14.94% |
| 2015 | 2.7230 | 24.39% |
| 2016 | 3.0225 | 11.00% |
| 2017 | 3.6486 | 20.72% |
| 2018 | 4.8397 | 32.65% |
| 2019 | 5.6765 | 17.29% |
| 2020 | 7.0166 | 23.61% |
| 2021 | 8.8615 | 26.29% |
| 2022 | 16.5632 | 86.91% |
| 2023 | 23.7851 | 43.60% |
| 2024 | 32.8303 | 38.03% |
| 2025 | 39.4897 | 20.28% |
Figures are displayed to four decimal places, and percentage changes were calculated from the underlying values before rounding. There is no annual observation for 2026 because the year was incomplete when this guide was prepared. The 9 October rate discussed later is a separate daily observation, not a directly comparable continuation of this annual table.
The series shows a sustained increase in lira per dollar, but does not establish a single cause for every year. The 2021 average also conceals differences between months, while the 2022 average may reflect the persistence of high rates reached earlier. The table should therefore be read alongside the sequence of policies and shocks, without mistaking an observation's database date label for a transaction date.
One mathematical distinction is crucial: a rise in the dollar's lira price does not translate into an equal percentage fall in the lira's dollar value. The relationship is reciprocal. If the dollar's local-currency price doubles, the lira loses half its dollar value, not all of it. We apply this distinction to specific historical observations below.
8. 2018: Imbalances Meet a Shock to Confidence
In its retrospective assessment, the International Monetary Fund linked the lira's weakness to domestic and external imbalances: an economy operating above estimated capacity, high inflation, a debt-financed external deficit and private-sector currency mismatches between revenues and liabilities. These vulnerabilities were then exposed to worsening sentiment towards emerging markets and geopolitical developments. The central point is that the shock hit already-sensitive balance sheets; a single political news event cannot explain the entire episode.
On 13 September 2018, the central bank raised the one-week repo rate from 17.75% to 24%, an increase of 625 basis points, or 6.25 percentage points. Inflation reached about 25% in October, according to the IMF's assessment. These figures refer to particular periods and should not be presented as if they all occurred on the same day.
The official dollar buying rate was 3.7719 lira in the 2017 year-end comparison and 5.2609 on 31 December 2018. Between these observations, the dollar's lira cost rose by about 39.48%, while the lira's dollar value fell by about 28.30%. This compares two year-end points; it is neither the crisis's largest movement nor the 2018 annual average shown earlier.
Consider a company that earns lira revenues but pays dollar liabilities: it needs more lira to meet those payments before it can adjust prices or increase revenue. The outcome differs if it has dollar export revenues, hedging arrangements or different payment dates. Exchange-rate changes therefore do not affect every company or household uniformly; their impact depends on the currencies of income and obligations and the timing of settlement.
9. 2019–2020: The Shock Subsides, Then the Pandemic Arrives
The Bank held its policy rate at 24% during the first half of 2019, then reduced it to 12% through meetings in the second half. Its report attributed disinflation to several factors, including lira stability, fading exchange-rate effects, weak demand and import prices. Inflation can therefore fall through more than one channel; the change should not be attributed solely to interest rates.
The pandemic then changed trade, tourism and demand conditions in 2020. The annual report describes weak activity at the outset, followed by credit expansion as conditions normalised, and also links rising inflation to lira depreciation. In November, the rate rose from 10.25% to 15%, then to 17% in December. Describing the whole year simply as a period of “hikes” or “cuts” omits the change of direction within it.
A shock of this kind affects both demand and supply. Companies may face weaker sales while finding inputs harder to obtain or shipments delayed. Lower external services revenue can reduce foreign-currency inflows, while import demand may also change. Neither the claim that recessions always lower prices nor the idea that credit expansion explains all inflation is sufficient during such disruption.
This is why crisis analysis requires monthly data, with annual averages retained as a way to summarise the trend. The 2020 average combines contrasting conditions; it neither describes the market in November alone nor measures the direct effect of a particular decision.
10. 2021: Rate Cuts and the Introduction of FX-Protected Deposits
The Bank raised its rate from 17% to 19% in March 2021, held it unchanged from April to August, then cut it by a total of five percentage points between September and December to 14%. Its rationale at the time included an assessment that supply pressures were transitory. Here we record the historical decision and its stated rationale without treating that rationale as an established fact about every component of inflation. Consumer inflation ended the year at 36.08%.
These conditions saw the introduction of exchange-rate-protected deposit arrangements, known as KKM. On 21 December, the central bank announced a facility for converting existing foreign-currency deposits into lira term deposits. At maturity, it compared interest or profit payments with the exchange-rate change. If the exchange-rate-adjusted value exceeded principal plus interest, the central bank covered the difference under the facility described in that announcement. This does not mean that all historical versions of the programme shared the same funding institution or terms.
The programme illustrates the distinction between choosing a deposit's currency denomination and allocating currency risk. An account can be denominated in lira while carrying conditional protection linked to exchange rates. A larger share of such accounts does not, by itself, establish that sensitivity to the dollar has disappeared from depositors' expectations or from the obligations of the institution covering the difference.
Protection against exchange-rate movements is also not full protection against domestic inflation. Price changes can erode purchasing power even when protection under another benchmark is delivered. The original announcement made the benefit conditional on reaching maturity; early withdrawal was not treated in the same way. KKM should therefore be understood as a historical instrument with specific terms and periods, rather than a general guarantee suitable for every saver in every year.
11. 2022: Energy, Commodities and Cumulative Exchange-Rate Pass-Through
The Bank's 2022 report linked import and price pressures to global energy and commodities, the effects of Russia's war in Ukraine and transport costs, alongside the impact of lira depreciation in late 2021. The Bank continued cutting rates from 14% to 9% between August and November. Annual inflation reached 85.51% in October, then 64.27% in December.
To understand overlapping shocks, the lira cost of an imported input equals its foreign-currency price multiplied by the exchange rate, before transport, duties and distribution are added. If the world price rises while the lira weakens, the two effects compound. The entire increase cannot then be attributed solely to global prices or solely to the currency. Imported inputs can also raise the cost of locally manufactured goods, transmitting the shock to products consumers may not regard as imports.
This period illustrates a common misunderstanding: inflation falling from 85.51% to 64.27% does not mean prices fell by the same amount or returned to their old level. It means the annual rate of increase slowed while remaining positive. The rate can also change because it is being measured against a high base in the previous year.
The distinction matters for households and businesses. Lower inflation may improve planning, but it does not automatically restore the previous purchasing power of a salary that failed to keep pace with prices. Nor does it, on its own, reduce replacement inventory costs to the cost of older stock. Price levels and income should be tracked alongside rates of change, rather than one being substituted for another.
12. 2023–2024: Tightening Begins and the Policy Rate Peaks
On 22 June 2023, the Bank announced the start of monetary tightening and raised the repo rate from 8.5% to 15%. The rate reached 42.5% in December, 45% in January 2024 and 50% in March. At the end of December 2024, it was reduced to 47.5%. This is the path of a particular policy instrument; it does not automatically describe every market lending or deposit rate.
Selected one-week repo decisions, not annual averages
| Decision date | Rate after the decision | Announced change |
|---|---|---|
| 22 June 2023 | 15% | Tightening begins from 8.5% |
| 21 December 2023 | 42.5% | Raised from 40% |
| 25 January 2024 | 45% | Raised from 42.5% |
| 21 March 2024 | 50% | Raised from 45% |
| 26 December 2024 | 47.5% | Reduced from 50% |
| 17 April 2025 | 46% | Raised from 42.5% |
| 11 December 2025 | 38% | Reduced from 39.5% |
| 22 January 2026 | 37% | Reduced from 38% |
Interest rates work through financing costs, demand, credit, asset choices and expectations, but their effects take time and vary between participants. Services prices and contracts adjusted periodically may respond slowly, while market indicators can change much faster. One month after a rate hike is therefore insufficient to judge its full effects, just as high inflation does not prove that tightening had no effect at all.
Annual inflation reached 75.45% in May 2024, then 44.38% in December. The fact that inflation peaked after rates had risen is a reminder that policy decisions also respond to inflation and risk. The relationship is not a simple experiment in which one factor changes while everything else remains constant.
A balanced reading separates what was announced, what happened and the explanation for that outcome. The announced rate is a dated fact; the change in inflation is another. Establishing each instrument's contribution requires more than comparing two numbers. Subsequent nominal rate cuts can also coexist with restrictive financial conditions if expectations, liquidity and credit constraints change.
13. 2025: Policy Changes Direction and New KKM Accounts End
The 2025 cycle was not an uninterrupted sequence of cuts. After reductions brought the repo rate to 42.5% in March, the Bank raised it to 46% on 17 April. Cuts resumed in July to 43%, followed by 40.5% in September, 39.5% in October and 38% in December. These decisions show how policy can change direction within a year in response to financial and inflation risks.
In its assessment published in February 2026, the IMF recorded the turbulence of March 2025, with capital outflows, lira weakness and reserve losses, alongside a broader improvement in demand for lira during the stabilisation period. That assessment should not be read as a description of conditions in October 2026: its information window and publication date are different. Causal analysis also requires separating the annual trend from an episode of pressure within it.
On 23 August 2025, the Bank terminated KKM account openings and renewals, excluding YUVAM accounts, while existing accounts remained valid until maturity. Saying that “openings and renewals ended” is more precise than saying all balances disappeared on the announcement date. A decision affecting new flows is different from the outstanding stock, a distinction that also matters in credit and deposit statistics.
The exit raises questions about how risk shifted: did lira savings become less dependent on exchange-rate compensation, and how did financing costs, deposit terms and confidence change? These questions require a sequence of data, rather than a programme name alone. Discontinuing an instrument does not automatically remove the reasons it was introduced or guarantee that everyone is protected against inflation and currency volatility.
14. Through October 2026: A Dated Snapshot, Not a Full-Year Result
In the latest decision available at this guide's preparation date, issued on 10 September 2026, the Bank held the one-week repo rate at 37%, the overnight lending rate at 40% and the overnight borrowing rate at 35.5%. September consumer inflation was 29.73% year on year and 1.84% month on month. The latest official exchange-rate observation displayed in the Bank's service at the review date was for 9 October and was an indicative rate.
Different periods and instruments: check the dates before comparing
| Indicator | Value | Date or period | How to read it |
|---|---|---|---|
| Policy rate: one-week repo | 37% | 10 September 2026 decision | Rate on a central bank policy instrument |
| Overnight lending | 40% | 10 September 2026 decision | Interest-rate corridor boundary; not a customer's deposit rate |
| Overnight borrowing | 35.5% | 10 September 2026 decision | A different instrument from the repo |
| Documented weighted average funding cost | 40% | Reporting period of the 13 August 2026 report | Do not automatically carry it forward to October |
| Annual consumer inflation | 29.73% | September 2026 | Compared with the same month a year earlier |
| Monthly consumer inflation | 1.84% | September 2026 | Compared with August |
| US dollar: indicative buying rate | TRY 49.1274 | 9 October 2026 | Per US dollar; not an annual average |
| US dollar: indicative selling rate | TRY 49.2160 | 9 October 2026 | A separate column from the buying rate |
The 40% figure needs particular care. The Inflation Report published on 13 August stated that one-week repo auctions had not been held since 2 March and that funding and sterilisation operations were conducted at the overnight lending rate, with a weighted average funding cost of 40% during the reporting period. The announced policy rate thus remained 37%, while the cost of implementation differed. The first figure should not be relabelled as 40%, nor should August's funding cost be presented as the latest daily cost on 11 October.
The “dollar buying rate” is also the buying side from the perspective of the institution quoting the rate; it does not mean every customer can buy dollars at that price. An indicative rate differs from a bank or exchange bureau's quote, and physical banknotes have separate rate columns. The daily observation cited here describes neither the end of 2026 nor its annual average.
Falling annual inflation alongside a monthly rise in the index is not a contradiction: prices may be rising this month more slowly than in the corresponding month a year earlier. Nor does the aggregate figure describe every household's experience, since food, housing and transport may have different weights in its budget from those in the statistical basket.
15. The Mechanisms: Exchange Rates, Real Interest, Confidence and Reserves
Exchange-rate movements affect prices directly through imported goods and indirectly through inputs and production costs. Pass-through is neither immediate nor a fixed percentage across all sectors: contracts, inventories, competition, margins and demand all matter. Exchange-rate pressures can therefore ease while some prices continue rising, or global energy prices can rise despite relative currency stability.
Nominal interest differs from real interest. For an illustrative comparison over a one-year horizon, the exact formula is: Real interest rate = [(1 + nominal interest rate) ÷ (1 + inflation) − 1] × 100, entering the rates as decimals. For a forward-looking decision, use expected inflation over the same horizon; when measuring a realised outcome, use actual inflation and the return for the matching period.
For example, a hypothetical annual interest rate of 40% with inflation of 30% produces a real rate of 7.69% before fees and taxes, rather than the 10% obtained by simple subtraction. Nor does subtracting 29.73% inflation from a 37% policy rate establish a saver's real return: one is past inflation and the other is the rate on a short-term policy instrument, not a guaranteed annual savings contract.
Definitions that prevent misleading conclusions
| Concept | What it measures | Mistake to avoid |
|---|---|---|
| Nominal exchange rate | The number of lira per unit of another currency | Equating it directly with domestic purchasing power |
| Inflation | The change in the price level of a specified basket | Treating slower inflation as a return to old prices |
| Real interest rate | The inflation-adjusted return over a matching horizon | Confusing the policy rate with a customer's return |
| Real exchange rate | The exchange rate adjusted for differences in price levels | Assuming every nominal depreciation implies equal real depreciation |
| Gross reserves | Reserve assets under a specified definition and date | Equating them with reserves net of liabilities |
| Outstanding deposits | The stock at a particular point in time | Equating it with new account openings during a period |
Reserves provide another example of why definitions matter. A rise in the dollar price of gold can increase the dollar value of reserves without the entire increase representing a new foreign-currency inflow. Gross holdings also differ from measures net of liabilities and swaps, depending on the definition used. Comparisons therefore require a common date and clearly specified components.
Confidence influences willingness to hold lira or refinance obligations, but it cannot be measured by a slogan or a single decision. Consistency in the policy framework, communication, price expectations and the fulfilment of obligations help explain it. Reading these elements together is more useful than assuming that the interest rate alone mechanically determines the exchange rate.
16. Measuring Value: Why a Dollar Rise Is Not an Equal Lira Fall
Let E denote the number of lira needed to buy one US dollar. When the rate moves from E0 to E1, the percentage increase in the dollar's lira cost is: (E1 ÷ E0 − 1) × 100. The percentage loss in the lira's dollar value, when E rises, is: (1 − E0 ÷ E1) × 100. The percentages differ because the denominator changes when the exchange-rate quotation is inverted.
If the dollar rises from a hypothetical 25 lira to 50, its lira cost increases by 100%, while one lira buys half as many dollars as before, a 50% loss in dollar value. A doubling of the dollar rate cannot be described as a 100% loss in the lira's value: that would mean its value had fallen to zero, which is mathematically different.
Specific comparisons: calculated percentages, not claims about the entire crisis
| Observations or example | E0 | E1 | Increase in the dollar's lira cost | Loss in the lira's dollar value |
|---|---|---|---|---|
| End-2000 → end-2001, official buying rate | 0.671765 | 1.439567 | 114.30% | 53.34% |
| End-2004 → end-2005, official buying rate | 1.3421 | 1.3430 | 0.07% | 0.07% |
| End-2017 → end-2018, official buying rate | 3.7719 | 5.2609 | 39.48% | 28.30% |
| Hypothetical doubling example | 25 | 50 | 100% | 50% |
The 2000 and 2001 observations were converted from old lira by dividing by one million, as was the 2004 observation, so that the table consistently uses the post-2005 unit. The comparison between end-2004 and end-2005 spans a full year; it does not prove that removing zeros itself caused a 0.07% market movement. The figure describes two observations expressed in a common unit.
This loss against the dollar also differs from a loss of purchasing power against the Turkish consumer basket. Basket prices and income may change at different rates. Using the official buying rate keeps the calculation consistent, but does not account for actual transaction fees or the buying–selling spread a customer may face.
17. Worked Examples: Salaries, Imported Inputs and Property
The following examples show why the measure must match the question. Start with a fixed TRY 100,000 and a dollar rate that moves from 40 to 50. The amount initially equals USD 2,500 and subsequently USD 2,000, a 20% decline in dollar value even though the dollar's lira cost rose by 25%. The number of lira is unchanged, but the comparison benchmark differs. This calculation alone says nothing about what TRY 100,000 can buy within Türkiye.
For an importer, a USD 1,000 input invoice at a rate of 40 costs TRY 40,000. If the foreign-currency price is unchanged and the dollar rises to 50, the cost becomes TRY 50,000. If the foreign-currency price also rises by 10%, the invoice becomes USD 1,100, or TRY 55,000. The combined increase is 37.5%: 1.10 × 1.25 − 1 = 0.375. Simply adding 10% and 25% gives 35% and misses the compounding effect.
Now suppose a property rises from TRY 5 million to TRY 6 million, a nominal increase of 20%, while the dollar rate moves from 40 to 50. Its dollar equivalent falls from USD 125,000 to USD 120,000, a 4% decline. In a separate calculation, assuming domestic inflation of 25% over the same period, its real price change is also minus 4%: 1.20 ÷ 1.25 − 1. The identical results here are a coincidence of the assumed figures; they do not make the dollar equivalent to the price index.
The example excludes rent, expenses, taxes, improvements and selling costs. It therefore measures only a price change, not a complete investment return. When cash flows are included, each flow's date and currency must be established. Converting flows from every period at one exchange rate and calling the result an actual return would be misleading.
18. Frequently Asked Questions and What to Monitor Next
Does lower inflation mean shops will cut prices? Not necessarily. A lower positive inflation rate means prices are rising more slowly. Some items may fall while others rise. The index level and its detailed changes determine the outcome, not the annual rate alone.
Do high interest rates guarantee a stronger lira? There is no guaranteed rule. Inflation expectations, risks, external flows, liquidity and timing all matter, and a decision may already be reflected in market prices. The rate alone is therefore insufficient to establish the outcome.
Did deposits stop being linked to the dollar as soon as KKM ended? The August 2025 decision concerns openings and renewals, with the stated exception and existing accounts running to maturity. Assessing balances and behaviour requires subsequent data and clear account definitions; it cannot be inferred from the decision alone.
Can the 9 October rate be used as the 2026 average? It is a specific daily observation of an indicative rate, different from a full-year average, a year-end rate or a customer's execution rate. The annual table above ends in 2025 to keep comparisons consistent.
What should be monitored to understand the trend?
| Question | Useful data | Essential checks |
|---|---|---|
| Are price increases accelerating? | Monthly inflation and the underlying trend | Seasonality, contributing items and period |
| Has the currency weakened externally? | A clearly specified exchange-rate series | Buying or selling; daily observation or average |
| How tight is policy? | Repo rate, funding cost and liquidity | Instrument and operating date |
| Have expectations changed? | Dated expectations surveys | Horizon and surveyed group |
| Has the capacity to absorb pressure improved? | Reserves, liabilities and flows | Gross versus net measures and valuation effects |
| How has a person or business been affected? | Income, obligations and prices | Currency, maturity and costs |
Good monitoring starts with a specific question and a matching measure. To understand the cost of an imported product, separate its foreign-currency price from exchange rates and transport. To assess a salary, compare income with the relevant spending basket. To read an interest-rate decision, identify whether the announced rate changed or the method of funding and implementation changed.
A short record of dates, instruments and units helps prevent comparisons between a daily snapshot and an annual average, or between realised inflation and a future expectation. Where binding contracts, foreign-currency obligations or tax consequences are involved, applying the analysis requires a specialist who can examine the documents and circumstances; arithmetic alone does not settle legal or accounting details. Historical understanding shows how these mechanisms change and interact, giving readers tools to distinguish reliable information from hasty conclusions.
