The number of banks on the Federal Deposit Insurance Corp.’s “problem” list grew over the summer, even as the industry posted solid net income and fewer loans soured. The number of troubled banks rose to 860 in the July-September quarter from 829 in the previous quarter. That’s the most since 1993, during the savings and loan crisis.

The FDIC also said banks earned $14.5 billion during the third quarter. That was a decrease from the previous quarter’s result of $21.4 billion.
