Fed officials vague on when to trim U.S. stimulus By Jonathan Spicer Fri Aug 23, 2013 10:25am EDT (Reuters) - Three U.S. Federal Reserve officials weighed in on Friday on the key question of when to reduce the central bank's bond buying, but their divergent views offered little more clarity for investors trying to predict what will happen at a Fed policy meeting next month. The comments by Atlanta Fed President Dennis Lockhart, his St. Louis counterpart, James Bullard, and John Williams of the San Francisco Fed all suggested U.S. monetary policymakers want to keep their options open headed into a much-anticipated meeting in Washington on September 17-18. U.S. bond prices and, in recent days, currencies in some emerging markets, have fallen sharply as investors increasingly expect the Fed will trim its $85-billion monthly asset-purchase program, which is meant to boost U.S. hiring and growth. "I would be supportive in September as long as the data that comes in between now and then basically confirm the path we're on," Lockhart said on CNBC television. "The key question is, do we have even at this moderate pace of growth a sustainable picture, something that's going to continue?" he asked. Or is there risk that the economy gets knocked off its feet in some way? Lockhart, a centrist who does not have a vote on policy this year, added during a separate television interview that he "wouldn't rule out September, but it could be later." Bullard, who does have a policy vote and has been sounding the alarm on low inflation readings, was also on television reiterating his view that the Fed need not rush to reduce the pace of quantitative easing, or QE3, in September. "I don't think we have to be in any hurry in this situation," he said. "Inflation is running low, you've got mixed data on the economy, so I'd be cautious and I wouldn't want to pre-judge the meeting," Bullard added. I think we want to take our time, assess what's going on, before we make a move here. Such mixed messages are common from the Fed's 19 policymakers, and they reflected the noncommittal tone in minutes of the central bank's July 30-31 policy meeting. The minutes, released on Wednesday, showed a few Fed officials thought then that it would soon be time to slow the pace of bond buying "somewhat," while others counseled patience. Primary dealers surveyed just before that July meeting said they expected a $15 billion reduction in September, according to a poll published by the New York Fed on Thursday. They expected a $10 billion reduction in Treasury buys and a $5 billion trim to mortgage-bond purchases. Williams, echoing a QE3-reduction plan first put forth by Fed Chairman Ben Bernanke in June, was mum on September but said the decision should hinge on economic data. The Fed needs to see "positive signs of momentum and growth in job creation, and we need to see inflation continue to edge back up toward our 2-percent longer-run inflation goal," Williams said. If the data continue to progress as we've seen, then I do agree that we should ... taper our purchases later this year. The three were speaking on the sidelines of a high-profile monetary policy conference in Jackson Hole, Wyoming, where many of the world's top central bankers meet annually. This year, however, Bernanke is not attending. In June, Bernanke set off an abrupt and widespread market selloff when he said the Fed expected to trim QE3 later this year and end the program altogether around mid-2014, depending on how the economy progresses. While U.S. growth is still tepid and the unemployment rate remained high at 7.4 percent last month, that rate is down from 8.2 percent a year earlier and economic data has been mostly encouraging in the last few months. The Fed has kept interest rates near zero since 2008. It launched its latest round of bond-buying in September, 2012. Reporting by Jonathan Spicer; Editing by Dan Grebler
