외국은행 국내지점 및 국내 시중은행의 수익성과 이자율 기간구조 간의 관계에 관한 비교 분석

The purpose of this paper is to empirically analyze the determinants of foreign bank Korea branches’ profitability by focusing on the interest rate term structure which best represents foreign bank Korea branches’ business characteristics. According to empirical results, firstly, substandard-and-below ratio, sales and administrative cost ratio have a negative effect on profitability, and loan balance ratio and fee ratio have a positive one on profitability in both foreign bank Korea branches and domestic banks, derivatives balance ratio has a positive effect on profitability only in foreign bank Korea branches. Secondly, short-term Korean interest rate has a positive effect on domestic banks’ profitability and a negative effect on foreign bank Korea branches. Furthermore, the difference between yield curve slopes in KRW and USD markets has a positive effect on profitability of foreign bank Korea branches. These empirical results show that there exist common and different determinants in making profitability between foreign bank Korea branches and domestic Korean banks. This paper has provided implication on interest rate differential and the different sensitivity on yield curve slope to Korean banks who try to expand to overseas such as Southeastern countries.
