The economy's continuing struggles aren't just confounding ordinary Americans. They've also stumped the head of the Federal Reserve.
Fed Chairman Ben Bernanke told reporters Wednesday that the central bank had been caught off guard by recent signs of deterioration in the economy. And he said the troubles could continue into next year.
"We don't have a precise read on why this slower pace of growth is persisting," Bernanke said. He said the weak housing market and problems in the banking system might be "more persistent than we thought."
It was the Fed chief's most explicit warning yet that the economy will face serious challenges next year. For several months, he had said the factors working against economic growth appeared to be "transitory."
The Fed cut its forecast for economic growth this year to a range of 2.7 percent to 2.9 percent from an April forecast of 3.1 percent to 3.3 percent. It also cut its forecast for next year to a range of 3.3 percent to 3.7 percent from an earlier 3.5 percent to 4.2 percent. The Fed also said unemployment would stay higher than it had expected earlier.
The Fed's statement Wednesday stood in contrast to the Fed's more upbeat view when officials last met, eight weeks ago. At that time, the central bank said the job market was gradually improving.
Since then, the economic news has been gloomy. The government reported that the economy grew at an annual rate of only 1.8 percent in the first three months of the year. It isn't expected to grow much faster in the current quarter. The economy added 54,000 jobs in May, far fewer than in the previous two months. Consumer spending has weakened, too.
