He is fighting to keep the economy afloat after mighty blows from the housing and credit crises, while trying to contain inflation.
For now, the priority is shoring up the economy, Bernanke suggested in an appearance before the. He pledged anew to slice a key interest rate and help the economy, which many fear is on the verge of a recession, if not already in one.
"The economic situation has become distinctly less favorable" since the summer, the Fed chief told lawmakers.
Since then, the housing slump has worsened, credit problems have intensified and the job market has deteriorated. Bernanke said that combination of bad news has made people and businesses more cautious about spending and investing, further weakening the economy.
The country should prepare for "sluggish economic activity in the near term," Bernanke said. Concern is growing about the possible return of stagflation, when stagnant growth is combined with rising inflation, for the first time since the 1970s.
Were energy prices to continue to rise at a sharp clip — something the Fed does not anticipate — it would "create a very difficult problem" for the economy, Bernanke said. Inflation would spread and growth would be further restrained, he said. If that happened, it would be a "very tough situation," he added.
The Fed is prepared to lower rates again to bolster economic growth, Bernanke said. The Fed "will act in a timely manner as needed to support growth and to provide adequate insurance against downside risks," he said, sticking closely to assurances he offered earlier this month.
The central bank started lowering a key interest rate in September. Over just eight days in January, the Fed shaved 1.25 percentage points, the biggest one-month reduction in a quarter-century. Economists andpredict the Fed will cut rates again at its next meeting, March 18. Some analysts believe rates will drop again in April.
Brian Bethune, economist at Global Insight, said Bernanke's remarks "keeps the door wide open for further rate cuts."
On, the edged up 9.36 points.
Bernanke said that at some point this year, the Fed will need to "assess whether the stance of monetary policy is properly calibrated" to foster the Fed's objectives of price stability "in an environment of downside risks to growth."
He was hopeful that previous rate reductions and the $168 billion economic aid plan of tax rebates for people and tax breaks for business would energize the economy in the second half of 2008.
As the Fed chief began his first day of back-to-back appearances on Capitol Hill to discuss the economy, there was more bad news on the housing and manufacturing fronts. Sales of new homes fell in January for a third straight month. Orders to factories for big-ticket manufactured goods dropped in January by the largest amount in five months.
Bernanke has come under some criticism for not acting sooner in cutting rates. But, the committee's top Republican, expressed sympathy. "There is perhaps no other public figure in America who has been subjected to as much Monday morning quarterbacking as you have" over the past months, Bachus said.
The committee chairman,, D-Mass., suggested the economy is not suffering through a garden-variety slowdown.
He made clear that he wasn't trying to put the R-word — recession — in Bernanke's mouth. "I'm not going to be responsible for the nervous people at the stock market who overreact when you twitch your nose," Frank told Bernanke. "But the problems we now have are different."
Many of those woes are linked to the housing meltdown. Bernanke was asked when he thought the housing market might stabilize. It's possible, he said, that by "later this year it will stop being such a big drag directly" on the economy. But home prices probably will decline into next year, he added.
"It is very difficult to know, and we've been wrong before," Bernanke said.
Even as the Fed tries to bolster the economy, it must remain mindful of inflationary pressures, Bernanke said.
Oil prices, which have set records, briefly shot past $102 a barrel on Wednesday; prices eased, but still remain close to $100 a barrel.
"Should high rates of overall inflation persist," Bernanke said, "the possibility also exists that inflation expectations could become less well-anchored." If people think inflation is escalating, they will act in ways that could make things even worse, a sort of self-fulfilling prophecy. Bernanke said that could complicate the Fed's job of trying to nurture growth while keeping inflation under control.
If oil prices continue to skyrocket this year, it would be "hard to maintain low inflation," Bernanke acknowledged.
