“The Fed chairman brushed off the risks of asset bubbles in response to a presentation on the subject from the group, one person said. Among the concerns raised, according to this person, were rising farmland prices and the growth of mortgage real estate investment trusts. Falling yields on speculative- grade bonds also were mentioned as a potential concern, two people said. The ‘first line of defense’ if bubbles emerge ‘needs to be regulatory and supervisory’ actions rather than changes in monetary policy, according to Bernanke.”
