In the U.S., the shadow banking debate has primarily focused on the money market fund industry. CFO.com reported that a number of large money market fund sponsors are adopting changes before the SEC publishes expected money market fund amendments. These sponsors are publishing the daily net asset values of selected funds, mostly those used by institutional investors, a development, which CFO.com believes will be welcomed by corporate treasurers. The Huffington Post speculated on whether the voluntary steps taken by some fund complexes will be enough to discourage the SEC from requiring more disclosure. It also commented on the timing of the decision to disclose NAVs, noting that markets are not currently under stress and wondering what will happen when a fund's NAV falls below $1. BusinessWeek reported that SEC Commissioner Daniel Gallagher predicted that the SEC would publish its proposed rules by the end of March.

On February 1st, the President of the New York Federal Reserve Bank, William C. Dudley, discussed the role of wholesale funding (namely the tri-party repo market and money market funds), the vulnerabilities presented by reliance on these short-term markets, and possible steps that could be taken to reduce those risks. After reviewing the more traditional reforms proposed to address the risk, Dudley suggested the expansion of the range of financial intermediation activity that is directly backstopped by the central bank's lender of last resort function.
