Liquidity restrictions on investors, like the redemption gates and liquidity fees introduced in the 2016 money market fund (MMF) reform, are meant to improve financial stability during a crisis. However, by comparing the latest outflow episode due to COVID-19 to those in 2008 and 2011, this column finds evidence that these liquidity restrictions might have exacerbated the run on prime MMFs in this episode. Such severe outflows amid frozen short-term funding markets led the Federal Reserve to intervene with the Money Market Mutual Fund Liquidity Facility (MMLF). By providing ‘liquidity of last resort’, the MMLF successfully stopped the run on prime MMFs and gradually stabilised conditions in short-term funding markets.
