This essay discusses the economic case for regulating shadow banking. Focusing on systemic risk, shadow banking is defined as leveraging on collateral to support liquidity promises. Regulating shadow banking is efficient because of the negative externality stemming from systemic risk. However, because uncertainty undermines the precise measurement of systemic risk, quantity regulation is preferable to a Pigovian tax to cope with this externality. This paper argues that regulation should limit the leverage of shadow banking mainly by imposing a minimum haircut regulation on the assets being used as collateral for funding.
