The rise in bond yields was due to what?

A top Federal Reserve official said Friday long-term bond yields may have risen in the wake of the launch of the central bank’s bond-buying program because market participants expected more purchases than were ultimately announced. Says Yellen

It was no secret that the Fed wanted dollar inflation. From the time the Fed announced the word was, go buy foreign, before the dollar inflates. So the last quarter, as the Fed started, domestic private investment dropped and foreign dollar inestments started. Any change in monetary policy requires an adjustment period. Since the announcement, the trade weighted dollar is down 3 points, and the adjustment is likely finished.
