The Fragility of an MMF-Intermediated Financial System


Abstract: Since the financial crisis of 2007-09—and, in particular, the run on prime money market funds (MMFs) in September 2008—policymakers have been concerned that the funds’ fragility may render banks themselves more susceptible to risk. For instance, in a recent article and speech arguing in favor of MMF reform, New York Fed President Bill Dudley stated that MMF fragility may contribute to financial market systemic risk. The idea that the susceptibility of MMFs to runs may make the financial system more unstable seems intuitive, but is it correct? In this post, we show that the idea isn’t only intuitively appealing, it’s also sound from an economic theory standpoint: MMF fragility is indeed a concern for the stability of the banking system and a contributing factor to financial market systemic risk.
