Federal Reserve Vice Chair
The whole speech is worth reading, but pretty much this is the most important line:
Turning to the potential costs of the Federal Reserve's asset purchases, there are some that definitely need to be monitored over time. At this stage, I do not see any that would cause me to advocate a curtailment of our purchase program.
This echoes the same sentiment expressed by Bernanke, himself, in a speech from Friday, wherein he said:
In light of the moderate pace of the recovery and the continued high level of economic slack, dialing back accommodation with the goal of deterring excessive risk-taking in some areas poses its own risks to growth, price stability, and, ultimately, financial stability. Indeed, as I noted, a premature removal of accommodation could, by slowing the economy, perversely serve to extend the period of low long-term rates.
