Mortgage problem gets much worse, another threat to financial system

Oh, happy day. Mortgages issued in the first half of 2007 are going bad at a rate much faster than those issued in 2006. According to The Wall Street Journal, data from the "Federal Deposit Insurance Corp. shows that 0.91% of prime mortgages from 2007 were seriously delinquent after 12 months, meaning they were in foreclosure or at least 90 days past due. The equivalent figure for 2006 prime mortgages was just 0.33% after 12 months."

The news means that earnings could get worse at large banks that have mortgage loans at the center of their businesses. Wachovia (NYSE: WB) and Washington Mutual (NYSE: WM) come to mind. That should be especially interesting for investors in the two companies. Over the last month, both stocks have recovered. Washington Mutual is up about 2% and Wachovia has risen a remarkable 30%.

Wall Street had hoped that bank stocks, especially those with businesses focused on the mortgage markets, would improve as subprime loans worked their way through the system. That may have worked if prime mortgages weren't going bad at an increasing rate these days and loans from 2007 didn't appear to present more risk than those from earlier periods.

All of that is to say that a stock like Wachovia, which fell as low as $7.80 and then recovered to $18.41, is not out of the woods. As a matter of fact, it may be heading back in.
