In Turkey, benchmark interest rates are set by the Central Bank of the Republic of Turkey Monetary Policy Committee (Türkiye Cumhuriyet Merkez Bankasi - TCMB). From June 1st 2018, the main interest rate is the one-week repo rate and the overnight borrowing and lending rates will be determined at 150 bps below/above the one-week repo rate. The central bank simplified its monetary policy framework on May 28th 2018 from a different system with four main key rates, with the late liquidity window lending rate being one of the most followed.
