Leaders of the U.S. central bank said Wednesday that they were holding their benchmark lending rate at a low level — in a range between 1 and 1.25 percent — for the time being. Federal Reserve officials said in a report issued after their two-day policy meeting that the world's largest economy was growing at a "moderate" pace and the job market was improving, but that inflation remained a bit low. Fed officials cut short-term interest rates to nearly zero during the 2007-09 financial crisis to boost investment and growth. They said the recovering economy no longer needed so much help, so they have been gradually raising interest rates and are expected to boost them further in the future. Leaving interest rates too low for too long risks sparking inflation that could damage the economy. During the recession, the Fed also tried to boost growth by cutting long-term interest rates, with a complex program that involved purchasing huge amounts of securities. Fed officials said they would keep these assets for the time being but indicated they would begin selling them off "relatively soon." Fed officials have said they will take care to reduce these assets in a gradual way that will not disrupt markets.
