Minimum capital requirements are a central tool of banking regulation. Setting them balances a number of factors, including any effects on the cost of capital and in turn the rates available to borrowers. Standard theory predicts that, in perfect and efficient capital markets, reducing banks'...

We propose a theory of regulatory arbitrage by banks and test it using trust preferred securities (TPS) issuance. From 1996 to 2007, U.S. banks in the aggregate increased their regulatory capital through issuance of TPS while their net issuance of common stock was negative due to repurchases. We...

Although nation-based systems of financial regulation constitute a second-best approach to global welfare maximization, treacherous accountability problems must be acknowledged and resolved before regulatory cooperation can deal fairly and efficiently with cross-border issues. To track and...

We study a modification of the Diamond and Dybvig (1983) model in which the bank may hold a liquid asset, some depositors see sunspots that could lead them to run, and all depositors have incomplete information about the bank's ability to survive a run. The incomplete information means that the...

Countercyclical capital buffers (CCyBs) are an old idea recently resurrected. CCyBs compel banks at the core of financial systems to accumulate capital during expansions so that they are better able to sustain operations during downturns. To gauge the potential impact of modern CCyBs, we compare...

Much attention has been paid to the large decreases in value of non-agency residential mortgage-backed securities (RMBS) during the financial crisis. Many observers have argued that the fall in prices was partly driven by decreased liquidity and fire sales. We investigate whether capital...

We develop a model of the joint capital structure decisions of banks and their borrowers. Strikingly high bank leverage emerges naturally from the interplay between two sets of forces. First, seniority and diversification reduce bank asset volatility by an order of magnitude relative to that of...

Banks can create liquidity because their deposits are fragile and prone to runs. Increased uncertainty can make deposits excessively fragile in which case there is a role for outside bank capital. Greater bank capital reduces liquidity creation by the bank but enables the bank to survive more...

This paper examines how the risk based capital standards, the so-called Basle Accord between 1990 and 1993. As the Japanese stock prices fell, banks' latent capital gains, which are part of tier II capital, became smaller. Empirical findings are consistent with a view that banks with lower...

What is the relationship between bank capital, the risk of a financial crisis, and its severity? This paper introduces the first comprehensive analysis of the long-run evolution of the capital structure of modern banking using newly constructed data for banks' balance sheets in 17 countries...
