Toward a Run-Free Financial System

Abstract

The financial crisis was a systemic run. Hence, the central regulatory response should be to eliminate run-prone securities from the financial system. By contrast, current regulation guarantees run-prone bank liabilities and instead tries to regulate bank assets and their values. I survey how a much simpler, rule-based, liability regulation could eliminate runs and crises, while allowing inevitable booms and busts. I show how modern communications, computation, and financial technology overcomes traditional arguments against narrow banking. I survey just how hopeless our current regulatory structure has become. I suggest that Pigouvian taxes provide a better structure to control debt issue than capital ratios; that banks should be 100% funded by equity, allowing downstream easy-to-fail intermediaries to tranche that equity to debt if needed. Fixed-value debt should be provided by or 100% backed by Treasury or Fed securities.
