Turkey’s Consumer Price Index (CPI) rose 30.87% year on year in March. This was below the 31.4% figure expected.
The data indicates that annual inflation eased relative to that forecast. The release adds a new March reading for Turkey’s price growth.
Inflation Surprise Signals Policy Traction
The lower-than-expected inflation figure of 30.87% for March suggests that the aggressive monetary tightening is finally taking hold. This is the first significant downside surprise in inflation we have seen in several quarters. This development should provide some temporary support for the Turkish Lira against the dollar.
We should remember the central bank aggressively hiked the policy rate to 50% back in January 2026 to front-load its inflation fight. With this new data, the market will likely reduce bets on any further rate hikes this year. Traders could consider positioning in interest rate swaps to reflect a peak in the policy rate.
Implied volatility on USD/TRY options, which had been elevated above 25% for the one-month tenor, is expected to decline on this news. The easing uncertainty makes it less attractive to pay high premiums for protection against Lira depreciation. This environment may favor strategies that involve selling volatility for those betting on a period of relative calm.
For equities, this is a clear positive signal, as a potential peak in interest rates reduces pressure on corporate borrowing costs. The BIST 100 index, which already rallied over 40% during 2025 on the back of the policy shift, may see renewed buying interest. We could see traders increasing long positions in BIST 100 futures or buying call options to capture further upside.
