The current account deficit has continued as a constant problem due to the structural problems of the Turkish economy and the impact of the tightening monetary policy decisions taken after the 2008 global crisis. For this reason, measures regarding the current account deficit are among the priority agenda items of the CBRT. The aim of this study is to examine the relationship between the current account deficit and the policy interest rate in the inflation targeting and floating exchange rate system using the ARDL bounds test method in the period 2011:Q1-2023:Q1. Cointegration results confirm the existence of a long-term relationship between the variables. Long and short term coefficients show that the policy rate does not have a significant effect on the current account deficit.The findings indicate that the expected impact of policy rate adjustments on the current account deficit is limited. It is thought that this situation arises from the fact that the reaction of the exchange rate to the policy interest is more decisive in inflation targeting than the reaction of the current account deficit. Therefore, keeping the current account deficit at a sustainable level will depend on exchange rate stability.
