There may be more problems. I notice this story in the news today:
Fed Grants GMAC's Request to Become Bank-Holding Company
Wall Street Journal - 28 minutes ago
By JON HILSENRATH and APARAJITA SAHA-BUBNA The Federal Reserve approved GMAC LLC's application to become a bank holding company, giving the struggling auto-financing arm of General Motors Corp.
I associate the current crisis with mortgages. Making GMAC a bank might mean auto loans are defaulting in significant numbers. Banks might hold car loans.
