Regulators on Friday shut banks in Georgia, Michigan, Minnesota, Missouri, and California, bringing the number of bank failures this year to 120 amid the struggling economy and a cascade of defaults on loans.

The Federal Deposit Insurance Corp. took over United Commercial Bank in San Francisco, with $11.2 billion in assets and $7.5 billion in deposits. East West Bancorp Inc., parent company of East West Bank based in Pasadena, Calif., is buying all of the deposits and most of the failed bank's assets.

The FDIC also closed United Security Bank, based in Sparta, Ga., with $157 million in assets and $150 million in deposits; Home Federal Savings Bank in Detroit, with $14.9 million in assets and $12.8 million in deposits; Prosperan Bank, based in Oakdale, Minn., with $199.5 million in assets and $175.6 million in deposits; and Gateway Bank in St. Louis, with $27.7 million in assets and $27.9 million in deposits.

Ameris Bank, based in Moultrie, Ga., agreed to assume the assets and deposits of United Security, while Liberty Bank and Trust Co., based in New Orleans, is buying the assets and deposits of Home Federal Savings.

Alerus Financial of Grand Forks, N.D., agreed to assume the assets and deposits of Prosperan Bank, while Central Bank of Kansas City is buying the assets and deposits of Gateway Bank.

The failure of United Commercial Bank is expected to cost the federal deposit insurance fund an estimated $1.4 billion; the failure of the other four banks a combined $132.7 million.

With United Security, 21 Georgia banks have failed this year, more than in any other state. Most of the failures have involved banks in the Atlanta area, where the collapse of the real estate market brought economic dislocation. Failures also have been especially concentrated in California and Illinois.

As the economy has soured, with unemployment rising, home prices tumbling and loan defaults soaring, bank failures have cascaded and sapped billions out of the federal deposit insurance fund. It has fallen into the red.

Depositors' money _ insured up to $250,000 per account _ is not at risk, with the FDIC backed by the government. The FDIC still has billions in loss reserves apart from the insurance fund. It can also tap a Treasury Department credit line of up to $500 billion.

Last week, regulators shut nine banks owned by holding company FBOP Corp. It was a new milestone: nine was the highest number of banks closed in a day since the financial crisis began taking down banks last year. Minneapolis-based US Bancorp bought the deposits and most of the assets of the banks, which included two others in California, three in Texas, two in Illinois and one in Arizona.

Banks have been especially hurt by failed real estate loans. Banks that had lent to seemingly solid businesses are suffering losses as buildings sit vacant. As development projects collapse, builders are defaulting on their loans.

If the economic recovery falters, defaults on the high-risk loans could spike. Many regional banks, especially, hold large concentrations of these loans. Nearly $500 billion in commercial real estate loans are expected to come due annually over the next few years. Continued...
