WASHINGTON -- The Federal Reserve has sent its strongest vote of confidence in the U.S. economy since the Great Recession struck six years ago: It decided the economy is finally strong enough to withstand a slight pullback in the Fed's stimulus.
Yet the Fed also made clear it was hardly withdrawing its support for an economy that remains below full health. Chairman Ben Bernanke stressed at a news conference that the Fed would still work to keep borrowing rates low to try to spur spending and growth and increase very low inflation.
The Fed said in a statement after its policy meeting ended Wednesday that it will trim its $85 billion-a-month bond purchases by $10 billion starting in January. And Mr. Bernanke said the Fed expects to make "similar moderate" cuts in its purchases if economic gains continue.
At the same time, the Fed strengthened its commitment to record-low short-term rates. It said it plans to hold its key short-term rate near zero "well past" the time when unemployment falls below 6.5 percent. Unemployment is now 7 percent.
Nevertheless, Wall Street seemed elated by the Fed's finding that the economy has steadily strengthened, by its firm commitment to low short-term rates and by the only slight amount by which it's paring its bond purchases.
The stock market, which had traded flat to down Wednesday going into the announcement, rallied enough for the Dow Jones Industrials and the S&P 500 to close at record highs. The Dow finished at 16,167.97, up 292.71 or nearly 2 percent, while the broader S&P 500 rose 29.65 to finish at 1,810.65, up 1.7 percent. The Nasdaq finished at 4,070.064, up 46.384 or 1.2 percent.
Apprehension over what the Fed would do had contributed to the market's slide over the past week. Many investment advisers had recommended that their clients be ready to buy on the dip and some of their advice was evidently heeded Wednesday.
Mr. Bernanke "encouraged investors enough that you had this money that went to the sidelines get back in again," said Ronald Heakins of OakTree Investment Advisors in Shadyside.
But Chris Wiles, a Mt. Lebanon investment adviser, was at a loss to explain the market's reaction.
"I'm thrilled, I guess," he said. "We could have had the exact same rally if they said we're not going to taper yet."
The Fed's bond purchases have been intended to drive down long-term borrowing rates by increasing demand for the bonds. The prospect of a lower pace of purchases could mean higher loans rates over time.
Bond prices fluctuated, but by late afternoon the yield on the 10-year Treasury note had barely moved. It inched up to 2.89 percent from 2.88 percent.
"We're really at a point where we're getting to the self-sustaining recovery that the Fed has been talking about," Scott Anderson, chief economist of Bank of the West. "It really seems like that's going to come together in 2014."
The Fed's move "eliminates the uncertainty as to whether or when the Fed will taper and will give markets the opportunity to focus on what really matters, which is the economic outlook," said Roberto Perli, a former Fed economist who is now head of monetary policy research at Cornerstone Macro.
But Mr. Perli noted that the Fed will continue to buy bonds every month to keep long-term rates down and remains strongly committed to low short-term rates. By keeping rates historically low, the Fed "will continue to remain very supportive of risky assets" such as stocks, Mr. Perli said.
The stock market has enjoyed a spectacular 2013, fueled in part by the Fed's low-rate policies. Those rates have caused many investors to shift money out of low-yielding bonds and into stocks, thereby driving up stock prices. Still, the gains have been unevenly distributed: About 80 percent of stock market wealth is held by the richest 10 percent of Americans.
For-profit educator Education Management led Pittsburgh regional stocks on Wednesday, jumping 64 cents to close at $11.29 per share. Other winners on a percentage basis included Wabtec, which rose $2.50 to finish at $74.11 per share; Bank of New York Mellon, up $1.03 to $33.89; and specialty steel producer Universal Stainless & Alloy Products, which closed at $35.37, up $1.02.
The handful of regional stocks falling included EQT, down $1.20 to $84.64, and 3-D printer ExOne, off 14 cents to $52.58.
In updated economic forecasts it issued Wednesday, the Fed predicted that unemployment would fall a bit farther over the next two years than it thought in September. And it expects inflation to remain below the Fed's target level.
The Fed expects the unemployment rate to dip as low as 6.3 percent next year and 5.8 percent in 2015. Unemployment has fallen faster this year than policymakers had predicted.
And Fed policymakers predict that their preferred inflation index won't reach its target of 2 percent until the end of 2015 at the earliest. For the 12 months ending in October, the index is just 0.7 percent.
The Fed worries about very low inflation because it can lead people and businesses to delay purchases. Extremely low inflation also makes it costlier to repay loans.
In its statement, the Fed says it will reduce its purchases of mortgage- bonds and Treasury bonds each by $5 billion. Beginning in January, it will buy $35 billion in mortgage bonds each month and $40 billion in Treasurys.
The bond purchases have helped keep long-term interest rates low to encourage more borrowing and spending.
The Fed's actions were approved on a 9-1 vote. The only member to object was Eric Rosengren, president of the Federal Reserve Bank of Boston. He called the move premature because unemployment remains high and inflation extremely low.
The Fed's action comes after encouraging reports that show the economy is accelerating.
Hiring has been robust for four straight months. Unemployment is at a five-year low of 7 percent. Factory output is up. Consumers are spending more at retailers. Auto sales haven't been better since the recession ended 4½ years ago.
What's more, the stock market is near all-time highs. Inflation remains below the Fed's target rate. And the House has passed a budget plan that seems likely to avert another government shutdown next year. The Senate is expected to follow suit.
The economy is improving consistently, and the Fed is "now recognizing the trend and decided to go with the flow," said John Silvia, chief economist at Wells Fargo.
