The toxic asset issue if far from over:

Toxic Loans Topping 5% May Push 150 Banks to Point of No Return

More than 150 publicly traded U.S. lenders own nonperforming loans that equal 5 percent or more of their holdings, a level that former regulators say can wipe out a bank’s equity and threaten its survival.

The number of banks exceeding the threshold more than doubled in the year through June, according to data compiled by Bloomberg, as real estate and credit-card defaults surged. Almost 300 reported 3 percent or more of their loans were nonperforming, a term for commercial and consumer debt that has stopped collecting interest or will no longer be paid in full.

The biggest banks with nonperforming loans of at least 5 percent include Wisconsin’s Marshall & Ilsley Corp. and Georgia’s Synovus Financial Corp., according to Bloomberg data. Among those exceeding 10 percent, the biggest in the 50 U.S. states was Michigan’s Flagstar Bancorp. All said in second- quarter filings they’re “well-capitalized” by regulatory standards, which means they’re considered financially sound.

“At a 3 percent level, I’d be concerned that there’s some underlying issue, and if they’re at 5 percent, chances are regulators have them classified as being in unsafe and unsound condition,” said Walter Mix, former commissioner of the California Department of Financial Institutions, and now a managing director of consulting firm LECG in Los Angeles. He wasn’t commenting on any specific banks.
