An empirical analysis of the effects of market response to bank loan announcements in the Hong Kong stock market

Abstract

This study will validate several key results from previous studies of bank loan announcement effects by using the data from Hong Kong market following the 1997 Asian crisis. Banks are believed to play a unique role in financial market which could effectively reduce the problem of information asymmetry and moral hazard. Banks could access borrowers’ inside information which is not available to other participants. Thus bank loan announcements convey valuable information to the market, and market response of the stock price should be positive. However, because of the significant reform in both financial market and information market, the valuation of bank loan announcement conveyed need to be reconsidered. This study investigates whether banks are still “unique” in the financial market or whether they are like middlemen between borrowers and investors. Data used in this study is collected from the Hong Kong Stock Exchange Index, and a standard event study with the market model is applied in the research to conduct the empirical analysis. The results suggest bank loan announcements are associated with significantly higher positive abnormal returns than non-bank loan announcements. Based on the market model of event study, market response is found to be significantly positive for loan syndication, short maturity loan and borrower’s debt ratio, and negatively related to firm size and loan size. Bank loans with refinancing and capital expenditure and no specific purpose have significantly higher positive abnormal returns, and borrowers with property and industrial industry type have more significant positive abnormal returns compared to other industry type. The findings also suggest the Hong Kong stock market is efficient in both strong and semi-strong form for bank loan announcements. A strong evidence of information leakage problem is found for non-bank loan announcements. The results are generally consistent with the existing literature.
