T-rates dropped sharply before the QE2 purchases ever started and they have rebounded since. Such front-running is common in the treasury market. Your claim was that QE2 was monetizing the debt - that is not true. It is also misleading to think of QE2 as principally directed at interest rates of the treasury series. The purpose is broader. Sorry about saying $600M when it was $600B. Mia culpa. I do the same thing with gigabytes and terabytes. Things have gotten BIG. ij
