Staff Working Paper No. 975
By Benjamin King and Jamie Semark
Macroprudential authorities increasingly find themselves needing to assess, and act on, risks from outside the traditional banking system. How should they think about the costs and benefits of these actions? In this paper we present an approach to cost-benefit analysis for one topical issue related to non-banks – liquidity mismatch in open-ended funds (OEFs). In particular, we analyse the benefits and costs of more extensive use of swing pricing by UK corporate bond OEFs. Using several models, we quantify the impact of liquidity mismatch and swing pricing on corporate bond spreads and expected GDP growth. We estimate that greater use of swing pricing could reduce amplification of investment grade corporate bond spreads by around 8%, and improve the distribution of GDP growth. We discuss qualitatively the impact of swing pricing on fund liquidity buffers, and the possible costs of swing pricing. We conclude that there are likely to be financial stability benefits from more extensive use of swing pricing by UK corporate bond OEFs.
