Valuation effects of new capital issues by large bank holding companies

Bank regulators in the United States and other major industrial nations have agreed on a framework for regulating bank capital, proposing that all banking organizations maintain common equity and perpetual preferred capital equal to 4 percent of risk-adjusted assets. This proposal raises important questions about the effect of different capital definitions on banking organizations. This article examines the stock market valuation effects of banks' issuing securities that are considered regulatory capital over the 1982–1986 period. The results are consistent with Myers and Majluf's securities overvaluation hypothesis.
