This paper examines the effect of exchange rate risk on interest rates within the uncovered interest rate parity condition for Turkey. When the interest rate is measured with the Treasury auction interest rate and the exchange rate risk is measured with the conditional variance of the exchange rate, then we found that there is a positive relation between the exchange rate risk and interest rate with the data from December 1986 to January 2001.The adaptation of the flexible exchange rate regime in the 1970s and the accelerated integration of financial markets with globalization after the 1980s made the behavior of exchange rates important to understand financial aggregates. The purpose of this paper is to assess the effect of the exchange rate and its risk on interest rates for a small open economy, in this case, Turkey. The exchange rate fluctuations introduce a risk on a return of an asset in foreign currency, and foreign investors might want to be compensated with higher risk premium. Therefore, it could be expected that there is a positive relationship between the exchange rate risk and interest rates. This study tests and finds that the exchange rate risk affects the interest rates positively in Turkey for the period from December 1986 to January 2001. This study focuses on Turkey for several reasons. Firstly, the Turkish economy has opened up substantially since the 1980s with extensive developments in the financial sector. Secondly, high exchange rate depreciations and inflation have been the basic characteristics of the Turkish economy. Thus, observing the effects of exchange rate risk on the interest rates is more feasible in Turkey.To the best of our knowledge, there is no study that looks at the effect of exchange rate risk on interest rates. There are various studies that have examined the effect of exchange rate risk on bank stock returns (see Tai, 2000, and
