NEW YORK/WHITE SULPHUR SPRINGS, West Virginia (Reuters) - September could be an opportune time for the Federal Reserve to consider scaling back its assets purchase, an influential official of the U.S. central bank said on Friday, as he stressed that the Fed must take a long view of economic progress and not be blinded by the most recent data.
The remarks by Fed Governor Jeremy Stein drew the attention of economists and investors after he ticked off several examples of improvement in the labor market since the Fed launched its bond-buying program last September.
Stein's speech, and a separate one on Friday by Jeffrey Lacker, president of the Richmond Fed, had some parallels to efforts by other Fed officials earlier this week to soothe market anxieties about a pullback in the bond purchases.
Nonetheless, Stein and Lacker took a more aggressive tone on when the central bank's unprecedented policy accommodation might be reduced.
Even so, differences within the Fed over the strength of the economy were in view as a third policymaker, John Williams, president of the San Francisco Fed, shelved his earlier view that the Fed could stop buying bonds by late 2013, saying, "It's too early to cut back on our programs right now."
The Fed's purchase of Treasuries and mortgage bonds at a monthly pace of $85 billion has provided a huge flow of liquidity into financial markets, driving up assets from stocks to bonds.
Yields on the benchmark 10-year Treasury note rose after Stein's remarks, a sharp reversal of stabilization in the market earlier in the day.
Markets had dropped hard in the days after Fed Chairman Ben Bernanke last week said the Fed expected to pare back on its bond purchases, known as quantitative easing, later this year and to halt it altogether by mid-2014, as long as the economy progresses as expected. Unemployment will likely have fallen to about 7 percent by then, he said.
But Stein on Friday, in an unusual move, trained investors' attention on the Fed's September policy meeting, though the policy-setting Federal Open Market Committee next meets in July.
"The best approach is for the committee to be clear that in making a decision in, say, September, it will give primary weight to the large stock of news that has accumulated since the inception of the program and will not be unduly influenced by whatever data releases arrive in the few weeks before the meeting," said Stein, a voting member of the policy committee.
Data from early September "will remain relevant for future decisions," even if it does not play a primary role in any policy decision in September, he said, in a speech at the Council on Foreign Relations in New York.
"If the news is bad, and it is confirmed by further bad news in October and November, this would suggest that the 7 percent unemployment goal is likely to be further away, and the remainder of the program would be extended accordingly," he said.
Stein's comments drew a sharp reaction on expectations of the Fed's policy path.
"Stein's remarks cannot be lightly dismissed and raise risks that some on the committee may have already essentially decided on September," said Michael Feroli, chief U.S. economist at JP Morgan in New York.
Lacker also put September in focus, saying the Fed meeting that month "is certainly a candidate" for when the Fed could first reduce its pace of buying, though he said that economic data would be key.
Nearly half of the economists polled by Reuters this month expect the Fed to start reducing the pace of asset purchases in September.

EXPECT MORE VOLATILITY
Williams, who is a voter on Fed policy this year, gave no preferred timeline for reducing bond purchases, saying only that doing so would be appropriate "at some point." If inflation continues to come in below expectations, that could point to the need for more stimulus, not less, he said.
He called the recent rise in Treasury rates a "healthy" development because it suggests markets no longer assume the Fed will keep rates low forever.
Lacker, one of the central bank's most hawkish officials and a persistent critic of the latest round of bond buying, said it was "wise" for Bernanke to clarify the Fed's views on future bond buying, but he stressed policy would still be loose as the Fed reduces "the pace at which it is adding accommodation." Lacker is not a voter on policy this year.
Financial markets should brace for more volatility as they digest news of a reduction in quantitative easing, Lacker told a judicial conference in West Virginia, adding that it "should not interfere with the moderate-growth scenario that I have presented."
Williams said that the sudden rise in rates suggests some investors had become complacent about low rates and that froth had been building in some areas of financial markets.
"It's healthy to get some froth out of the market," he told reporters after his speech.
On the labor market, where unemployment remains high at 7.6 percent, Stein noted the rate was 8.1 percent when the bond purchase program was launched last year. Monthly job growth has jumped dramatically since then, he said, adding Fed forecasts are also more optimistic.
Stein said the Fed can be more specific about its plans for QE3 as it approaches its policy goals. The timeline Bernanke articulated illustrates a "greater willingness to spell out what the committee is looking for, as opposed to a 'we'll know it when we see it' approach," he said.
Still, Stein stressed that reducing the pace of QE3 is highly conditional on the economy. He added it did not mark a change in policy and was meant only to clarify things for investors.
Stein, a relatively new but highly respected member of the powerful Fed board, turned some heads back in February when he warned the massive asset purchases were showing signs of inflating price bubbles in junk bonds and other markets.
But on Friday he said while financial stability should play a roll in monetary policy decisions, the benefits of QE3 have surpassed the costs of the program, including such stability risks.
