Scaling the Twin Peaks: Systemic Risk and Dual Regulation

Abstract

In April 2013, the UK implemented a dual-regulation approach to financial services often referred to as twin peaks. In this paper, we assess the impact of the introduction of twin peaks regulation on the systemic risk contributions of UK financial institutions. Using a matched sample of single- and dual-regulated financial institutions, we provide evidence that twin peaks regulation resulted in a relative reduction in systemic risk for dual-regulated firms.
