QE2 is coming, and it isn’t stocks the Fed buys in large quantities with its quantitative easing. It buys treasury bonds, in an effort to drive long-term interest rates down, which should drive the price of bonds up. But the bond market hasn’t been as excited about the idea of all that buying as the stock market has been. In fact, just the opposite. Treasury bonds have been tumbling since late August. For instance, 30-year bonds have lost roughly 3.4% of their value in less than two months. That’s a noticeable hit to an income asset that yields roughly 3.9% a year.
