Turkey's gradual wind-down of its FX-protected deposit scheme — the program that guaranteed savers against lira depreciation in exchange for keeping balances in local currency — closes the most expensive currency-defense tool deployed in any major emerging market over the past decade. The scheme worked: it stabilized deposits, reduced dollarization, and bought time for monetary policy to normalize. It also accumulated a multi-trillion-lira contingent liability on the sovereign balance sheet. The unwind is the moment the rate-led orthodoxy has to prove it can sustain stability on its own.
Key takeaways
- The FX-protected deposit program is being phased out as orthodox policy stabilizes the lira.
- The scheme transferred exchange-rate risk from savers to the sovereign balance sheet.
- Successful exit depends on real rates remaining high enough to retain lira deposits voluntarily.
- The wind-down is the cleanest read on policy credibility post-normalization.
How the scheme worked
The mechanism was simple. Depositors who held lira-denominated time deposits at participating banks were guaranteed against any currency loss exceeding the deposit-rate yield. If the lira depreciated more than the interest rate compensated, the Treasury made up the difference. The result was that savers had a one-way option: dollar-equivalent returns with no downside on the currency. The behavioral effect was significant — dollarization slowed, deposits stayed in lira.
- Sovereign liability. Treasury bore the depreciation tail risk.
- Bank balance sheet. Lira deposits supported lira lending.
- Behavioral lock-in. Savers stayed local because the option was costless to them.
What the wind-down tests
Phasing out the scheme requires depositors to choose between lira-only deposits at orthodox real rates and dollar-equivalent alternatives. If real rates are credibly positive and the lira is reasonably stable, deposits stay. If either condition slips, dollarization could re-accelerate. The wind-down's pace is being calibrated to keep both conditions visibly intact, but the test is real.
The real-rate threshold
The voluntary-retention math requires real rates clearly above expected currency depreciation. The central bank has signaled commitment to maintaining the gap. Markets are watching for any softening of that signal.
The contingent-liability cleanup
The accumulated fiscal cost of the scheme has been substantial. Winding it down removes the contingent flow but does not retroactively cancel costs already incurred. The fiscal arithmetic improves at the margin only.
How Turkey's currency-defense toolkit has evolved
The instrument mix has rotated significantly across the past two cycles.
| Tool | Pre-orthodoxy | During normalization | Post-wind-down |
|---|---|---|---|
| Policy rate | Sub-inflation | Above inflation | Above inflation |
| FX-protected deposits | Major | Major, capped | Phased out |
| Reserve management | Active | Rebuilding | Conservative |
| Capital controls | Selective | Reduced | Minimal |
The most expensive currency-defense tool of the decade was effective, but the bill comes due in the form of fiscal liability and policy-credibility tests like this one.
Frequently asked questions
Could the scheme be reactivated in stress?
Operationally yes, politically yes, but the central bank has signaled strong preference against. Reactivation would itself be a credibility setback.
What is the deposit-retention signal?
The share of lira-denominated time deposits as participation tapers. Stability in that share confirms voluntary retention; declines flag stress.
How does the rating-agency view shift?
Positively if the wind-down is orderly. The removed contingent liability improves the sovereign profile. A rocky wind-down would have the opposite effect.
The bottom line
Turkey's FX-protected deposit wind-down is the most consequential post-stabilization policy step yet. It tests whether orthodoxy can hold deposits voluntarily and closes one of the largest contingent liabilities on the sovereign balance sheet. Doing it carefully is what makes the past two years of normalization stick.
