본고에서는 외환위기 이후 우리나라의 무위험 금리 평형조건 (covered interest rate parity)의 불균형 오차 (disequilibrium error)와 국내외 금리 및 현⋅선물환율개별충격과의 동태적 상관관계를 살펴보았다.
Abstract
This paper analyzes the dynsmics and determinants of disequilibrium error in the covered interest parity (CIP) thrpough the transformed error correction model following Kim and Park (2008), Kim (2008, 2009), Kim and Park (2008) and Kim (2009). According to the dynamic analyses including impulse response analyses and Granger causality test, I found the CIP disequilibrium error may be mainly caused not by the foreign exchange rate part but by the domestic and foreign interest part. However the dynamic effect of the CIP error to the interest rates and exchange rates was not meaningful. These results imply that there may be restrictions to hinder the arbitrage transaction to clear the CIP disequilibrium quickly. A restriction to this direction is the credit risk of Korean financial market and any policy reaction to reduce it may be necessary. For instance, any effort to inform the sound fundamentals of Korean economy in the international financial markets may be useful.
