The Central Bank of the Republic of Türkiye held its one-week repo policy rate at 37% at its 10 September 2026 meeting. Its statement pointed to a decelerating underlying inflation trend while also warning that elevated energy prices created upside risks. September's annual consumer inflation was subsequently reported at 29.73%.
High nominal interest rates are intended to influence spending, lending, savings and inflation expectations. They can make some forms of borrowing more expensive and encourage holding domestic-currency savings, but they can also raise financing costs for households and businesses. The relationship between the policy rate and the rate an individual borrower pays is not one-to-one.
The distinction between nominal and real returns matters. A 37% annualized policy rate should not simply be compared with a past twelve-month CPI rate as though that gives a guaranteed investment return. Expected inflation, taxes, product conditions and changing rates all affect the actual outcome.
DISCUSSION: Should Türkiye maintain restrictive rates until inflation expectations fall further, or is the cost to credit and investment becoming too high?
