FRANKFURT/STOCKHOLM/HOUGHTON, Michigan (Reuters) - The Federal Reserve confused financial markets over scaling back its bond buying, four top officials said on Thursday, with one arguing the central bank should link tapering to drops in the jobless rate and another calling for a broad remake of strategy.
Fed Board Governor Jeremy Stein said he would have been comfortable with acting at the September 17-18 meeting, and the decision to keep buying bonds at an $85 billion monthly pace had been, for him, a "close call".
"But whether we start in September or a bit later is not in itself the key issue - the difference in the overall amount of securities we buy will be modest," he told a monetary policy conference in Frankfurt.
"What is much more important is doing everything we can to ensure that this difficult transition is implemented in as transparent and predictable a manner as possible. On this front, I think it is safe to say that there may be room for improvement," he said in prepared remarks.
The Fed's decision to stand pat on bond buying stunned financial markets, which had anticipated it would begin to slowly reduce the program, signaling the beginning of the end to an unprecedented five years of ultra-easy monetary policy.
Federal Reserve Chairman Ben Bernanke explained the decision last week by pointing to the disappointing performance of the U.S. economy in the second half of 2013. He also noted headwinds from tighter U.S. fiscal policy, which could worsen as leaders in Washington fight over a deal to keep the government funded and lift the U.S. debt limit.
Investors are now focused on Fed meetings in October and December, although some economists say the central bank could hold its fire until 2014 to make sure the U.S. economy has decisively regained cruising speed.
But Richmond Federal Reserve President Jeffrey Lacker, one of the Fed's most hawkish officials who has been urging for months that it taper bond buying, said that the central bank had boxed itself in by failing to move last week.
"It could be hard to do it (tapering) in October without losing face, but I don't see why we couldn't do it," he told a banking conference in Stockholm. "It's going to be harder for us to communicate credibly in the future," he told reporters. Lacker is not a voting member of the policy committee this year.
Kansas City Fed chief Esther George, the lone dissenter at last week's meeting, also felt that the central bank had done its mission some harm by deciding not to taper.
"Delaying action not only allows potential costs to grow, it also has the potential to threaten the credibility and the predictability of future monetary policy actions," she told the Colorado Economic Forum at a dinner in Denver.
A fourth official, Minneapolis Fed chief Narayana Kocherlakota, said the Fed had only itself to blame if markets swing wildly in "misguided" reaction to its meeting-by-meeting decisions on bond buying.
"It is a problem of the (Fed's) own making, because we have not been sufficiently clear about what we are going to do down the road," he said.
Kocherlakota called for a renewed focus by Fed policymakers on bringing down unemployment, like former Fed Chairman Paul Volcker's single-minded focus on curbing inflation in 1979.
The central bank, he said, should do whatever it takes to drive U.S. unemployment lower, although not necessarily by buying even more bonds. For instance, it could lower the interest rate it charges banks to keep their excess reserves at the Fed, he said.
What matters is not the specific "tactic," he said, but the overall strategy.
"What the committee chose to do in September was fully consistent with everything that had been communicated," Kocherlakota told reporters after his talk. But what has been communicated, he said, is insufficient, as is the level of stimulus the Fed is providing the economy.
"I think we've set ourselves up in a very awkward position where every action, no matter how minute the economic consequences of that action, and every communication about that action, no matter how minute that communication might be, is having very undue consequences on people's beliefs about the course of future policy," he said. "We should be communicating more effectively that we are about having the economy recover as fast as possible, as long as inflation stays close to, possibly temporarily above, but close to 2 percent."
Kocherlakota is one of the Fed's most dovish members, and on Thursday he reiterated that the Fed should keep interest rates near zero until unemployment reaches 5.5 percent, though he cast doubt on whether the rate truly captured the state of the labor market.
The nation's jobless rate fell to 7.3 percent in August, but remains well above historically normal levels. The decline was also subject to caution because it reflected the departure of workers from the labor force, rather than being entirely due to stronger new job creation.
Stein, who has talked about the risk of Fed bond buying leading to asset bubbles, said that one way to reduce uncertainty and accompanying market volatility would be to link cuts in bond buying directly to economic data.
"For example, one could cut monthly purchases by a set amount for each further 10 basis point decline in the unemployment rate," he said.
