We discuss corporate governance reforms in the Korean banking sector, which include reforms in board composition and executive compensation, implemented after the Asian financial crisis in 1997 and examine the stock market's response to the reforms. We find that the banking returns and volatilities became more Granger-causally prior to both KOSPI and finance sector returns after 1998. The announcements of banking governance reforms are generally associated with significant increases in banking sector stock returns. The KIF survey finds that board governance is considered essential in assessing the value of the firm. The participants in the McKinsey survey indicate that they are willing to pay a premium of 24% on average for firms with outstanding corporate governance systems.
