Turkish lira deposit interest in 2026: is it worth it?

If you arrive from Iran used to single-digit dollar interest or rial interest that trails inflation, the "lira deposit interest" boards in Istanbul branches catch the eye: figures hovering around the central bank's policy rate, which has been 36% since 22 October 2026. The obvious question is whether putting money into a lira deposit is worth it, or whether the interest merely compensates for the lira's loss of value.

This article explains how a Turkish lira time deposit works, shows what adds to your return and what takes from it, and spells out the particular risk for someone whose base currency is the toman or the dollar. Every figure is dated and traceable in the sources. EL DÖVİZ offers no deposits or investment products and this is not financial advice; the aim is simply that you know what to ask when you walk into a branch.

How a lira time deposit works

A time deposit (vadeli mevduat) means placing a sum with a bank for a fixed term, such as one, three, six or twelve months, and receiving the agreed interest at maturity. A few general rules apply at almost every Turkish bank:

• The rate is locked for that term. The interest quoted at opening stays fixed until maturity, but a renewal for the next term uses the rate of the day, which may be higher or lower.
• Breaking the deposit early usually forfeits the interest. You get the principal back, but the interest for the term is either not paid or recalculated at a much lower rate. If you might need the money, choose a shorter term.
• Automatic renewal is a setting you should switch on or off deliberately; otherwise the money either returns to a non-interest current account at maturity or rolls over at the day's rate.
• The rate depends on amount and term. Banks quote different rates for larger sums and specific terms, and every bank differs from the next.

You need a Turkish bank account to open a deposit; if you do not have one yet, the guide to opening a bank account in Turkey covers the documents and the steps.

Why nominal rates are so high

High interest in Turkey is the product of high inflation, not generosity. The central bank keeps its policy rate (the one-week repo rate) high to bring inflation down, and banks price deposits around that number. At the time of writing (October 2026), the central bank cut the policy rate from 37% to 36% at its 22 October 2026 meeting, the first cut since 23 January of the same year. The overnight lending rate was set at 39% and the overnight borrowing rate at 34.5%.

Over the same period, annual consumer inflation published by the statistics office (TÜİK) stood at 29.73% for September 2026. Put the two numbers side by side and the logic of high rates is clear: interest has to at least match inflation for a depositor to keep their purchasing power in lira. Every new central bank decision shifts that balance, and a rate announced today is no guarantee for the next term.

What you keep and what is taken away

The rate on the board is nominal and gross. What actually reaches you passes through several deductions. The table below lines up the components; the figures are valid at the time of writing, and you should not compute a final result from them, because only you know your bank's rate and the exchange rate over your term.

Withholding tax

The bank deducts the tax when it pays the interest, so you file nothing. The rate depends on the term and is higher for shorter maturities. Public sources for 2026 report roughly 17.5% for terms up to six months, 15% for six to twelve months and 10% beyond a year, but these rates change by presidential decree and the sources disagree on the detail. The simplest approach is to ask the bank to write down the "net rate after tax".

Inflation

If your money is in lira and your spending is in lira, your yardstick is lira inflation: a net rate above inflation preserves purchasing power, one below it does not. Annual inflation for September 2026 came in just under 30%, with housing, energy and transport above the average, so the inflation of your personal basket may differ from the official figure.

The specific risk for a toman-based saver

Here is where you differ from a Turkish depositor. For you there are two conversions: toman or dollars into lira at the start, and lira back into toman or dollars at the end. Deposit interest only acts on the lira leg; if the lira weakens against the dollar during the term, part or all of the interest disappears in the second conversion. If the lira holds or strengthens, the result beats the nominal rate. Nobody knows the lira's path in advance, and this article makes no prediction.

A few practical points for exactly this situation:

• Lira that will be spent in Turkey, in lira, such as the next few months of rent and living costs, carries no second conversion risk; money that will go back into toman or dollars always does.
• A term that ends when the money is needed lowers the chance of breaking the deposit and losing the interest.
• Record the entry and exit rates. Without those two numbers you cannot tell whether you actually gained.
• Look at the rate history, not just today's figure. The Turkish lira rate page shows the reference rate; for an actual conversion, the rate and fee are confirmed before anything is done.

Why the lira has fallen so far in recent years is the subject of a separate article and is not repeated here.

FX-protected deposits no longer exist

You may have heard from friends about the "FX-protected deposit" (KKM), under which the state compensated depositors for the lira's fall. The scheme started in December 2021 and is no longer available: openings and renewals stopped for companies on 15 February 2025 and for individuals on 23 August 2025, balances ran down to zero by August 2026 and the related communiqués were repealed. A deposit you open today is an ordinary lira deposit, and the currency risk is entirely yours.

Deposit insurance: how far does safety go?

The Savings Deposit Insurance Fund (TMSF) guarantees individuals' deposits up to a ceiling. By a Fund Board decision of 4 December 2025, the ceiling rose from 950,000 TL to 1,200,000 TL per person per bank from the start of 2026. Two practical points: the ceiling applies per bank, and any amount above it in one bank is not covered. If your sum is large, factor that limit into your decision.

What to ask before you go to the branch

1. What is the interest rate for my amount and term, and until when is it valid?
2. What is the net rate after withholding tax?
3. What exactly do I lose if I withdraw before maturity?
4. How is automatic renewal set up, and how is the renewal rate determined?
5. Are there conditions or caps for a foreign or non-resident customer?
6. Do you also offer foreign-currency deposits (dollar or euro), and at what rate?

Get the answers in writing. The final decision depends on your own numbers: amount, term, entry and exit rates, and whether you will spend the money in lira in the end or convert it back to toman.

Where the exchange office fits in

EL DÖVİZ takes no deposits and gives no advice on them. What we can do is the two ends of the journey: converting toman or dollars into lira for a deposit into your own account, and at the end of the term, buying and selling lira to turn the sum back into your base currency. In both cases the rate and fee are confirmed before anything is done, and nothing happens until you approve. Put the deposit interest next to the cost of those two conversions and you will have a far more realistic answer to "is it worth it".
