Regulators on Friday shut down a total of seven banks in Florida, Georgia, Illinois, Kansas and Arizona, lifting to 139 the number of U.S. banks that have fallen this year as soured loans have mounted and the economy has sputtered.

The Federal Deposit Insurance Corp. took over the banks, the largest of which by far was Hillcrest Bank, based in Overland Park, Kan., with $1.6 billion in assets.
