Securities And Exchange Commission, U.s. Credit Rating Downgrade | featured news

Securities regulators have sent subpoenas to hedge funds and other trading firms as it probes possible insider trading before the U.S. government's long-term credit rating was cut last month, the Wall Street Journal said, citing people familiar with the matter.

The U.S. Securities and Exchange Commission (SEC) has asked rating agency Standard & Poor's (S&P) to disclose which employees knew of its decision to downgrade U.S. debt before it was announced last week, the Financial Times said, citing people familiar with the matter.

Standard & Poor's, whose unprecedented downgrade of U.S. debt triggered a worldwide stocks sell-off, is pushing back against a U.S. government proposal that would require credit raters to disclose "significant errors" in how they calculate their ratings.
