There is strong cirticism from many quarters about low interest rates as a prime culprit in causing the bubble in housing prices. In comments before the American Economic Association, America's Fed Chairman Bernanke defended his role as Fed governor in 2003 when he along with Greenspan was an advocate of the decision to cut the Fed's target interest rate to 1%, and to leave it here for a year and raise it only slowly. Bernanke says countries like Britain, New Zealand, and Sweden had tighter monetary policy but there home prices rose more, and monetary policy explains only 5% of the variation in home prices. Analysis has shown he says that capital inflows such as those the U.S. received from China and other Asian countries explains 31% of the variation in home prices, supporting a contrasting theory that that its these global imbalances that drove the crisis. He also placed the primary fault for the housing bubble on relaxed lending standards and views that housing prices would rise forever. Alongside these comments Fed chairman Bernanke also said that bank supervisors and other financial regulators of which the Fed was one, has a better ability to contain the excesses that led to the economic crisis including housing bubble and other excesses, than the Fed as a monetary policy maker. By saying this Bernanke is acknowledging that the failure of regulation was a key part of what happened in the economic crisis. The failure to fix the regulatory system even now leads Bernanke to say that he is open to using monetary policy as a supplementary tool for addressing risks should another bubble develop, if the regulatory system isn't reformed. Still Bernanke and Greenspan were quite complacent at the time of the low interest rates and did not point out the dangers of global capital imbalances which were evident at the time, preferring to say that the United States could benefit from the inflows of capital from overseas without serious risks. And the Fed did not exercize its role of vigilance in alerting the country to excesses in the way the housing industry operated and in exercizing its own powers to that effect. Instead the Fed as regulator and in role as asafeguard for serious risks let itself become part of the cheering section as the worst excesses in housing were being exposed....
