Regulators on Friday shut down seven banks in Illinois, putting the number of U.S. bank failures this year at 57.

There were 140 bank failures in the U.S. last year, the highest annual tally since 1992 at the height of the savings and loan crisis. They cost the insurance fund more than $30 billion. Twenty-five banks failed in 2008 and only three succumbed in 2007.

The number of bank failures likely will peak this year and will be slightly higher than in 2009, FDIC Chairman Sheila Bair said recently.

As losses have mounted on loans made for commercial property and development, the growing bank failures have sapped billions of dollars out of the deposit insurance fund. It fell into the red last year, hitting a $20.9 billion deficit as of Dec. 31.
