I don't think [the Fed will be forced to raise rates]. I think Bernanke is obsessed with house prices because he knows how important house prices are for the net worth of the average American, and they're crucial. The fact that house prices are still declining has got to be telling him that QE2 is still not doing what he hoped it was going to do.
So, I think if house prices keep falling there's a good probability that he's not going to end QE2 and there may be a QE3.
