Concerns over tepid job growth prompted the U.S. central bank last year to embark on an open-ended bond buying program. It said it would keep up the program, which it hopes will push down borrowing costs, until it saw a substantial improvement in the outlook for the labor market.
The Fed also has committed to hold interest rates near zero until the unemployment rate reaches 6.5 percent, provided inflation does not threaten to push over 2.5 percent.
However, minutes of the January 29-30 policy meeting published on Wednesday showed some Fed policymakers feel the central bank may have to slow or stop the asset purchases before it sees an acceleration in job growth because of concerns over the costs of the program.
Economists polled by Reuters had expected first-time jobless applications to rise to 355,000. Last week's data covered the survey period for the February nonfarm payrolls report. Claims were up 27,000 between the January and February survey periods.
But this probably does not suggest any material change in the pace of job growth given that claims been very volatile since January because of difficulties smoothing the data for seasonal fluctuations.
With inflation pressures well contained and the labor market only gradually improving, a shift in Fed policy is unlikely.
Last month, the consumer price index was held back by weak gasoline prices and food prices, which were unchanged after rising over the past months, the Labor Department said.
Economists polled by Reuters had expected the CPI to edge up 0.1 percent. In the 12 months through January, consumer prices rose 1.6 percent, the smallest gain since July. They had advanced 1.7 percent in December.
However, consumer prices excluding food and energy rose 0.3 percent - the largest gain since May 2011. The so-called core CPI had increased 0.1 percent in December.
In the 12 months through January, core CPI increased 1.9 percent after rising by the same margin in December. That is just below the Fed's 2 percent goal.
Gasoline prices fell 3.0 percent after dropping 1.9 percent the prior month. But the decline in gas probably has run its course as prices at the pump have increased 44 cents so far this year.
Elsewhere, apparel prices increased 0.8 percent after gaining 0.1percent in December. New motor vehicle prices rose 0.1 percent after advancing 0.2 percent the prior month.
Prices for used cars and trucks rose 0.2 percent after six consecutive months of declines. Airline fares rose for a fifth month in a row.
Housing costs edged up, with owners' equivalent rent rising 0.2 percent.
