As Money Market Funds Close, Regulators Weigh Tougher Rules

Since late 2016, only government money market funds have been allowed to maintain a fixed $1 share price. Prime money market funds, which invest in floating-rate debt and commercial paper of non-Treasury entities, have a floating rate net asset value. That change prompted many large asset managers to convert some prime money market funds to government money market funds.

During the financial downturn in March and April, the Fed developed lending facilities to support the commercial paper market and primary and secondary corporate credit markets, but those supports may not be enough now, according to Quarles, who also lamented elevated redemptions from corporate bond funds.

"The Fed and other financial agencies have accomplished a lot in requiring or encouraging market participants to rely less on unstable short-term funding, but it is worth asking whether there may be other steps needed to secure these very important sources of liquidity."

Late last month SEC Chairman Jan Clayton expressed a similar sentiment. "There's no doubt that we need to reexamine the reforms of the last time," said Clayton, speaking on a virtual panel about the reforms enacted in 2016 though adopted in late 2014.
