Fears are growing that the nation’s largest savings and loan, Washington Mutual, and the nation’s largest insurance company, American International Group, could also go under. On Monday, Washington Mutual had its credit rating cut to junk by Standard and Poor’s. The bank’s stock value has dropped 94 percent over the past year. And the Wall Street Journal reports the Federal Reserve has asked Goldman Sachs and JPMorgan Chase to help make up to $75 billion in loans available to AIG. Stock in AIG plummeted 61 percent on Monday.
