A second area of ongoing reform is money market funds. In an important step toward greater stability, the SEC in 2010 amended its regulations to, among other things, require that money market funds maintain larger buffers of liquid assets, which may help reassure investors and reduce the likelihood of runs. Notwithstanding the new regulations, the risk of runs created by a combination of fixed net asset values, extremely risk-averse investors, and the absence of explicit loss absorption capacity remains a concern, particularly since some of the tools that policymakers employed to stem the runs during the crisis are no longer available. SEC Chairman Mary Schapiro has advocated additional measures to reduce the vulnerability of money market funds to runs, including possibly requiring funds to maintain loss-absorbing capital buffers or to redeem shares at the market value of the underlying assets rather than a fixed price of $1. Alternative approaches to ensuring the stability of these funds have been proposed as well. Additional steps to increase the resiliency of money market funds are important for the overall stability of our financial system and warrant serious consideration.
