Fed official wants to keep up quantitative easing as inflation expectations slip

ST LOUIS, Missouri (REUTERS) - The Federal Reserve should keep buying bonds for longer than planned in the face of volatile markets and falling inflation expectations, a top US central banker said on Thursday, even as another Fed policymaker warned against an over-reaction.

James Bullard, president of the St Louis Fed, is the only official at the central bank to publicly suggest putting on hold the Fed's widely telegraphed plan to halt its asset-purchase programme later this month.

Yields on US bonds, which have plunged the last few days, rebounded after his comments.

"We can go on pause on the taper at this juncture and wait until we see how the data shakes out into December," Bullard said on Bloomberg Television.

"Inflation expectations are dropping in the US and that is something that a central bank cannot abide."

"A reasonable response by the Fed in this situation would be to invoke the clause... that says the taper was data dependent," he added.

Encouraged by strengthening US growth and falling unemployment, the Fed has incrementally tapered its bond buying programme from US$85 billion originally to US$15 billion this month.

It was set to shutter the programme at a policy meeting Oct 28-29, a plan that Fed chair Janet Yellen may well stand by.

But stock market values and bond yields have dropped sharply in recent weeks as investors fretted over the health of the world economy, with fears growing that Europe could tip into recession, damaging the US economy.

The dollar has continued its climb, causing measures of medium-term inflation expectations to ease.

Bullard, who has long focused on inflation to inform his policy beliefs, had until Thursday been seen as a hawkish policymaker intent on closing the book on accommodation and raising interest rates starting early next year.

He said he was sticking with his forecast for a rate hike in the first quarter of next year for now, but wanted to see how the market turbulence played out.

While Bullard, who does not have a vote on policy this year or next, wants to keep buying US$15-billion in bonds for another couple of months, Philadelphia Fed President Charles Plosser said the selloff was not yet significant enough to hurt the US economy or to garner a response from the central bank.

The Fed should not overreact when the domestic economy looks stable, Plosser told reporters in Allentown, Pennsylvania.

"I don't think anything I've heard has suggested to me it's of a significance... to throw the US economy off the tracks," said Plosser, who has a vote on Fed policy. "It could, but at this point the numbers just aren't big enough to really get too excited."

Plosser acknowledged that a big selloff could harm US consumer demand, but added the strong job market would offset that. The Fed "would address it (depending on) how we thought it would affect inflation and employment," he said.

On Wall Street, the price of the 30-year US bond dropped more than one point and stocks rebounded after Bullard's comments.

Bets on the timing of a Fed interest rate rise have fallen back to October or December of 2015, from mid-2015 a few weeks ago, based on futures markets.

Fed vice-chair Stanley Fischer and New York Fed president William Dudley, among other core Fed decision-makers, have in recent days suggested mid-2015 was still reasonable timing for a tightening.

Speaking in Billings, Montana on Thursday, Minneapolis Fed president Narayana Kocherlakota repeated his view that a rate hike in 2015 would be inappropriate.
