Against that backdrop, builders slashed spending on housing projects by a whopping 25.2 percent on an annualized basis in the fourth quarter, the biggest cut in 26 years.
To limit the damage from the crises, the Federal Reserve has taken a number of extraordinary actions. It has slashed a key interest rate over the last two months by the most in a quarter century. And to relieve turmoil on Wall Street, which intensified after the crash of the country's fifth-largest investment firm, Bear Stearns, the Fed has resorted to its greatest expansion of lending authority since the 1930s. Big securities firms will temporarily be allowed to go to the Fed directly for loans — a privilege that had been afforded only to commercial banks.
With the nation's economic woes a top concern for voters, the White House and Democrats in Congress have been scrambling to provide relief. Democratic presidential candidate Barack Obama on Thursday called for an overhaul of financial regulations.
Consumers, whose spending is indispensable to the economy's vitality, boosted buying at a 2.3 percent pace in the fourth quarter. That was better than the 1.9 percent growth rate previously estimated but still marked a slowing from the third quarter's 2.8 percent pace.
Businesses — nervous about customers' waning appetite to buy given all the problems in the economy — cut back sharply on their inventories of unsold goods. That shaved 1.79 percentage points off fourth-quarter GDP, the most in more than two years.
Spending by businesses on equipment and software, meanwhile, rose at a pace of 3.1 percent in the final quarter of last year. That was slightly less than previously estimated and marked a slowdown from the prior quarter's 6.2 percent growth rate.
Businesses' profits also took a hit in the final quarter. A measure linked to the GDP report showed that after-tax profits fell 3.3 percent at the end of last year, after being flat in the prior quarter.
There was a bright spot in the mostly gloomy report, however. Sales of US goods and services to other countries grew at a 6.5 percent pace. That was better than the 4.8 percent growth rate previously estimated, although it was down sharply from the prior quarter's blistering 19.1 percent growth rate.
