WASHINGTON – Federal regulators on Friday shut down two big thrifts based in Southern California, saying they fell victim to the acute distress in the housing market in that state.

The failures of Downey Savings and Loan Association, based in Newport Beach, and PFF Bank & Trust of Pomona brought the number of U.S. bank failures this year to 22.

The Federal Deposit Insurance Corp. was appointed receiver of the two thrifts. U.S. Bank, based in Minneapolis, acquired all the deposits of both.

Downey, the 23rd-largest U.S. savings and loan, had assets of $12.8 billion and deposits of $9.7 billion as of Sept. 30. PFF, the 38th-largest, had assets of $3.7 billion and $2.4 billion in deposits.

Also Friday, Georgia regulators shut down The Community Bank, a small bank in Loganville, Ga. The FDIC was made receiver of the bank, which had $681 million in assets and $611.4 million in deposits as of Oct. 17. The FDIC said all the bank's deposits and about $84.4 million of its assets will be acquired by Bank of Essex, of Tappahannock, Va. Its four branches will reopen Monday as offices of Bank of Essex.

The 22 bank failures so far this year compare with three for all of 2007 and are far more than in the previous five years combined. It's expected that many more banks won't survive the next year of economic tumult. The pressures of tumbling home prices, rising mortgage foreclosures and tighter credit have been battering many banks, large and small, nationwide.

This year's failures also include Seattle-based thrift Washington Mutual Inc. in late September, the biggest bank collapse in U.S. history. It had $307 billion in assets.

Well over half of the roughly 8,500 federally insured banks and savings and loans are expected to tap the FDIC's temporary guarantees.

Of the 8,500 federally insured banks and thrifts, the FDIC had 117 on its internal list of troubled institutions as of June 30, a five-year high. The agency doesn't disclose the banks' names.
