U.S. regulators closed Ravenswood Bank of Chicago, bringing the 2010 total of failed banks to 109.

The Illinois Department of Financial and Professional Regulation closed the bank, which had $269.5 million in total deposits, $211 million in loans and two branches. Northbrook Bank and Trust Co., based in Northbrook, Ill., and a unit of Wintrust Financial Corp., agreed to acquire $190 million of assets and $120 million of deposits, according to Wintrust and the FDIC.

The FDIC said the failure is expected to cost the agency’s deposit-insurance fund about $68.1 million.
