Abstract

How does the shadow banking system respond to changes in the capital regulation of commercial banks? We propose a tractable, quantitative general equilibrium model with regulated and unregulated banks to study the unintended consequences of regulatory policy. Tightening the capital requirement from the status quo creates a safer banking system despite more shadow banking activity. A reduction in aggregate liquidity provision decreases the funding costs of all banks, raising profits and reducing risk-taking incentives. Calibrating the model to data on financial institutions in the U.S., we find the optimal capital requirement is around 15%.
