Bernanke said he didn't think so-called "operation twist" would do much to stimulate the economy but added it should "help somewhat." The move, he said, should push interest rates down by 0.2 percentage points. Bernanke also gave recommendations to Congress' new super committee that's tasked with cutting $1.5 trillion from federal deficits by the end of next month, saying they need to consider long-term budget constraints but not at the detriment of short-term economic growth. Bernanke also warned policymakers that they need to step up, saying "fostering healthy growth and job creation is a shared responsibility of all economic policymakers." "Monetary policy can be a powerful tool, but it is not a panacea for the problems currently faced by the U.S. economy," Bernanke said. Bernanke: A Greek default could hurt us When asked about China's continued policy to hold down the value of the yuan, Bernanke acknowledged that the Chinese policy is hindering the global economic recovery. However, Bernanke stopped short of endorsing a Senate bill that would slap new tariffs on Chinese imports in retaliation for their policy of devaluing their currency. The Fed chairman also gave his thoughts on the spate of protests on Wall Street, saying he thinks the protests show that "people are quite unhappy with the state of the economy." "They blame, with some justification, the problems of the financial sector," he said. He added the protesters are "dissatisfied with the policy response here in Washington. On some level, I can't blame them."
