WASHINGTON — The Federal Reserve said Friday that it will auction an additional $100 billion in April to cash-strapped banks as it continues to combat the effects of a credit crisis.

The central bank said it would make $50 billion available at each of two auctions, on April 7 and April 21.

Through the end of March, the Fed has provided $260 billion in short-term loans to commercial banks through the auction process. It also has employed Depression-era provisions to provide money to investment banks.

All the moves have been designed to cope with a serious financial crisis that has roiled U.S. and global markets and caused the near-collapse of Bear Stearns Cos., the nation's fifth-largest investment bank.
