The Federal Deposit Insurance Corp. said Thursday that surging levels of soured loans at banks dragged down profits in the April-June period. The $3.7 billion loss compared with profits of $7.6 billion in the first quarter, and $4.7 billion a year ago.

The FDIC also said the number of banks deemed to be in trouble jumped to 416 from 305 at the end of the first quarter. That’s the highest number since June 1994 during the savings and loan crisis.
