Lots of commercial real estate loans are going to go bust this year. The Fed is worried. From the minutes of the Federal Reserve's Open Market Commitee meeting last month:

Conditions in the commercial real estate (CRE) sector were still deteriorating. Bank credit had contracted further, and with many banks facing continuing loan losses, tight bank credit could continue to weigh on the spending of some households and businesses. Some participants remained concerned about the economy's ability to generate a self-sustaining recovery without government support. In particular, they noted the risk that improvements in the housing sector might be undercut next year as the Federal Reserve's purchases of MBS wind down, the homebuyer tax credits expire, and foreclosures and distress sales continue. Though the near-term outlook remains uncertain, participants generally thought the most likely outcome was that economic growth would gradually strengthen over the next two years as financial conditions improved further, leading to more-substantial increases in resource utilization.
