- Abstract
Following the financial crisis of 2007–2008, Basel III recommended that bank regulators include changes in the fair value of available-for-sale (AFS) debt securities in Tier 1 capital. However, the U.S. allowed smaller banks to continue excluding these changes through a one-time opt out election. This paper examines the investment decisions of smaller banks in the 1990s when changes in the fair value of AFS debt securities were temporarily included in regulatory capital. Using a sample of smaller banks and a difference-in-differences research design, we find that low-capitalized banks reduced their investments in more volatile asset classes (e.g., corporate bonds, non-agency MBS) and increased their investments in less volatile asset classes (e.g., treasuries and municipal bonds) after these changes were included. These findings suggest that providing smaller banks with an opt out election potentially allows low-capitalized, riskier banks to continue to hold more volatile securities in their AFS portfolios.
