FXstreet.com (Córdoba) - Moody's would announce downgrades to major world banks, including UK lenders today after the Wall Street closing, most likely near 21:00GMT, according to a story reported by Sky News earlier today.

Meanwhile, citing two people with knowledge of the plans, Bloomberg reports that Moody's Investors Service has told banks it may later today announce downgrades of the credit ratings of as many as 17 lenders and securities firms with global capital markets operations.

The move is expected as part of a broader credit downgrade of some of the world's major banks. Moody's has already downgraded major banks in several European countries, including Spain and Italy. Any downgrades could raise borrowing costs and force banks to increase collateral.
