Connected Funds

Abstract

Mutual funds often invest in other funds. In this paper, we analyze the economics behind such cross-fund investments and investigate their financial stability implications. Using granular data for the German fund sector, our main findings are that cross-fund investments (a) are becoming increasingly important over time, (b) were heavily liquidated during March 2020, and (c) display measurable contagion effects. Overall, cross-fund investments can elevate structural fund sector vulnerabilities.
