CBRT Maintains 37% Policy Rate Amid Energy Risks

On September 10, 2026, the CBRT Monetary Policy Committee (MPC) left the one-week repo policy rate unchanged at 37.0%. The decision marks the fifth consecutive hold, driven by concerns that rising Brent crude prices and geopolitical tensions, particularly involving Iran, could slow the decline in inflation. Policymakers emphasized that while disinflation is progressing, the "energy prices create upward risks on the inflation outlook."

Market Expectations Shift: Inflation Outlook Rises

The CBRT’s September Market Participants Survey, released on September 11, revealed a revision in inflation expectations. The year-end CPI increase forecast was raised to 29.61%, up from previous estimates. Concurrently, the 12-month forward USD/TRY exchange rate expectation settled at 58.60 TL, while the year-end dollar forecast was pegged at 51.57 TL. These figures suggest markets are pricing in a stickier inflation path despite the orthodox policy stance.

Reserves Dip to $65.66 Billion

Weekly data from the CBRT showed a decline in foreign exchange reserves for the week ending September 4. Net international reserves fell to $65.66 billion from $66.62 billion the prior week. Total official reserve assets decreased by 2.1% to $184.2 billion, with net reserves excluding swaps dropping to $53.4 billion. This reduction highlights the ongoing balance between maintaining liquidity support and preserving buffer stocks.

Analysts Signal Liquidity Over Headline Rates

Commerzbank analyst Tatha Ghose noted that while the headline rate remains at 37%, effective monetary conditions are increasingly defined by liquidity management tools rather than just the policy rate itself. ING analysts also pointed out that normalizing liquidity and lowering the effective funding rate have pushed market pricing closer to their 2026 rate views, suggesting the "orthodox" turn is working through transmission channels even without immediate rate cuts.

Local view

Local Turkish media outlets emphasized the "tight monetary policy" stance maintained by the CBRT. Habervakti highlighted the decision text’s explicit warning about energy prices posing upward risks to inflation. HaberGo noted that participation banks reached a record 200 billion TL in assets, reflecting shifts in the banking sector as traditional banks navigate high rates. Sabah focused on the survey results, noting the divergence between falling growth expectations (3.0%) and rising inflation forecasts.
