WASHINGTON — The country is stuck in a slow-growth rut, the Federal Reserve suggested Wednesday.

Higher prices for energy, food and other things are pinching people and businesses — reasons enough for the economy to be Americans' top concern heading into the presidential elections.

The Fed's report on business conditions around the nation provided fresh evidence of the toll that housing, credit and financial problems are taking on the economy as a whole.

With problems expected to persist into next year, the next president — be it John McCain or Barack Obama — is likely to face many challenges.

Heading into the fall, "economic activity has been slow" in most of the Fed's 12 regions, according to the report. Businesses described the climate as "weak" or "soft" or "subdued."

A growing number of analysts believe the economy could be thrown into a tailspin later this year and early next year as consumers and businesses curtail their spending even more.

"Over the course of this summer it became clear that the economic headwinds have not subsided as hoped," Eric Rosengren, president of the Federal Reserve Bank of Boston, said in a speech Wednesday.

"Most private forecasters are expecting significantly slowed growth in the second half of this year — as residential investment continues to be a drag on the economy, as consumers tighten up on their spending, as the impact of the federal tax rebate subsides, and as weakness among some of our major trading partners makes the outlook for many exports more restrained," he explained.

The Fed's report noted that consumers — major shapers of the economy — were cautious. Shoppers "concentrated on necessary items and retrenchment in discretionary spending," the Fed observed.

The Fed regions of Chicago, Dallas and San Francisco, for instance, reported noticeable declines in spending on clothing, electronics and jewelry. Sales of furniture and household appliances were weak in most parts of the country — victims of the housing slump.

Auto sales, meanwhile, tumbled, according to company reports out Wednesday. Ford Motor Co.'s U.S. sales fell 26.5 percent in August. Sales at General Motors Corp. dropped 20.3 percent from a year ago. Toyota's sales sank 9.4 percent.

Wall Street had a mixed reaction to all the news. The Dow Jones industrial average gained 15.96 points to close at 11,532.88. Other stock indexes dipped.

On the inflation front, many businesses and consumers felt the sting of high prices for food, energy and other things, the Fed reported. The recent drop in oil prices from a record-high of $147.27 in mid-July does give the Fed more leeway to keep its key rate steady. Oil prices closed at $109.35 barrel on Wednesday.

And, while businesses welcomed this drop, they told the Fed that prices still remain elevated. "Business contacts in a number of (Fed) districts indicated that they had increased selling prices in response to the high costs" for certain commodities.

Caught between dueling concerns of slow growth and inflation, the Fed is expected to leave a key interest rate alone at 2 percent when it meets Sept. 16 and probably through the rest of this year. The Fed at its last two meetings didn't budge the rate out of concerns about inflation. Before that, though, the Fed had aggressively cut rates to shore up the economy.
