Monetary Policy and Money Market Funds in Europe
As shown in a past Liberty Street Economics post, in the United States, the yields of money market fund (MMF) shares respond to changes in monetary policy rates much more than the rates of bank deposits; in other words, the MMF beta is much higher than the deposit beta. Consistent with this, the size of the U.S. MMF industry fluctuates over the interest rate cycle, expanding during times of monetary policy tightening. In this post, we show that the relationship between the policy rates of the European Central Bank (ECB) and the size of European MMFs investing in euro-denominated securities is also positive—as long as policy rates are positive; after the ECB introduced negative policy rates in 2015, that relationship broke down, as MMFs received large inflows during this period.
Pricing Liquidity without Preemptive Runs
Prime money market funds (MMFs) are vulnerable to runs. This was dramatically illustrated in September 2008 and March 2020, when massive outflows from prime MMFs worsened stress in the short-term funding markets and eased only after taxpayer-supported interventions by the Treasury and the Federal Reserve. In this post, we describe how mechanisms like swing pricing that charge a price for liquidity can reduce the vulnerability of prime MMFs without triggering preemptive runs.
Sophisticated and Unsophisticated Runs
In March 2020, U.S. prime money market funds (MMFs) suffered heavy outflows following the liquidity shock triggered by the COVID-19 crisis. In a previous post, we characterized the run on the prime MMF industry as a whole and the role of the liquidity facility established by the Federal Reserve (the Money Market Mutual Fund Liquidity Facility) in stemming the run. In this post, based on a recent Staff Report, we contrast the behaviors of retail and institutional investors during the run and explain the different reasons behind the run.
