The Globe and Mail reports in its Thursday edition the SEC has approved rules intended to prevent a repeat of an investor exodus out of money-market mutual funds as happened during the financial crisis. A Wall Street Journal item inside The Globe says the asset-management industry said it could live with the new regulations, which the Securities and Exchange Commission backed in a 3-2 vote. The rules would require prime money funds catering to institutional investors to abandon their fixed $1 share price and float in value like other mutual funds (all figures U.S.). Prime funds sold to individual investors can keep the $1 share price. The rules also allow all money funds to temporarily block investors from withdrawing cash in times of stress. Prime funds invest in short-term corporate debt; money funds that purchase short-term treasuries and other government debt are excluded from the floating-share-price requirement. Fidelity was among the fund companies that spent years lobbying the SEC against stricter regulation. The rules are aimed at making the $2.6-trillion money-fund industry less prone to investor runs by training institutional investors to accept fluctuations in the value of their investments.
