WASHINGTON - It's been almost an article of faith: Any recession this year will be mild and brief.
But now the stunning meltdown of a top Wall Street investment bank and stubbornly persistent financial market turbulence has called that into question, raising fears that severe problems in housing and the nation's bedrock financial system could cripple the economy and wallop many millions of Americans.
No less an authority than former Federal Reserve Chairman Alan Greenspan wrote this week that "the current financial crisis in the U.S. is likely to be judged as the most wrenching" since the end of World War II.
Other noted economists are also sounding alarms. Harvard professor Martin Feldstein, the former head of the National Bureau of Economic Research, said recently he believes the country is now in a recession and it could be a severe one.
While it will be many months before the bureau's cycle dating committee, the unofficial arbiter of when recessions begin and end, makes its own ruling, a growing number of private economists already have a downturn figured into their forecasts. They are generally calling for a mild recession that will end this summer when the economic stimulus checks going to 130 million households start getting spent.
But the severe credit crisis that erupted last August - and claimed its biggest victim this past weekend with the forced sale of Bear Stearns Co. - is raising doubts about those mild forecasts.
"Bear Stearns was a clear wake-up call. It resonates with everybody and highlights the severity of the stresses in the financial system," said Mark Zandi, chief economist at Moody's Economy.com.
What got people's attention was how quickly Bear Stearns, the nation's fifth largest investment bank, could go from a stock market value of about $3.5 billion when the market closed on March 14 to being sold at the bargain-basement price of about $236 million two days later.
The Federal Reserve rushed in to take unprecedented actions. It provided a $30 billion line of credit to facilitate the sale and is employing Depression-era provisions that for the first time are providing direct Fed loans to investment banks.
Most analysts said the Fed was justified and that its efforts highlighted the severity of the dangers facing the financial system.
The turmoil produced wild swings on Wall Street this week with the Dow Jones industrial average surging on Tuesday after the Fed aggressively cut a key interest rate only to plunge on Wednesday on renewed worries about the economy and then to stage a 262-point gain on Thursday. Markets were closed Friday.
More turbulence is expected in coming weeks because there remains a great deal of uncertainty about how many more victims the credit crisis will claim.
