Abstract

This paper investigated the information spillover effect between stock market and bond market with the KOSPI daily index and MMF yield data. The overall analysis period is from May 2, 1997 to August 30, 2019. The empirical analysis was conducted by dividing the period from May 2, 1997 to December 30, 2008 before the global financial crisis, and from December 30, 2008 to August 30, 2019 after the global financial crisis, and the overall analysis period. The analysis shows that the EGARCH model considering asymmetric variability is suitable. The price spillover effect and volatility spillover effect existed in both directions between the stock market and the bond market, and the price transfer effect was greater in the period before the global financial crisis than in the period after the global financial crisis. Asymmetric volatility in information between stock and bond markets appears to exist in both markets.

본 연구에서는 주식시장과 채권시장간의 정보 이전효과(information flow effect)를 살펴보기 위해 우리나라 KOSPI의 일일지수와 초단기 채권형 펀드(money market fund : MMF) 수익률 자료를 이용하여 분석하였다. 전체 분석대상 기간은 1997년 5월 2일부터 2019년 8월 30일까지 이다. 1997년 5월 2일부터 2008년 12월 30일 글로벌금융위기전 기간, 2008년 12월 30일부터 2019년 8월 30일까지 글로벌금융위기 후 기간과 전체기간으로 세분하여 실증분석을 하였다. 분석결과 비대칭적 변동성을 고려한 EGARCH 모형이 적합한 것으로 나타났다. 주식시장과 채권시장 간에는 가격이전효과와 변동성 이전효과가 양방향으로 존재하는 것으로 나타났으며, 가격이전효과는 두 시장 간에 글로벌금융위기전 기간이 후보다 더 크게 나타났다. 주식시장과 채권시장간의 정보에 대한 비대칭적 변동성이 두 시장에 존재하는 것으로 나타났다.
