Recession in the U.S. has arrived!

January 8, 2008 - The feared recession in the US economy has already arrived, according to a report from Merrill Lynch.

It said that Friday's employment report, which sent shares tumbling worldwide, confirmed that the US is in the first month of a recession.

Its view is controversial, with banks such as Lehman Brothers disagreeing.

But a reserve member of the committee that sets US rates warned that it could do little about the below-trend growth expected in the next six months.

"I am concerned that developments on the inflation front will make the Fed's policy decisions more difficult in 2008," Charles Plosser, president of the Federal Reserve Bank of Philadelphia said.

He was referring to the problems faced by the US Federal Reserve, which might want to cut interest rates to avoid a recession, but is worried about inflationary factors such as $100-a-barrel oil.

An official ruling on whether the US is in recession is made by the National Bureau of Economic Research, but this decision may not come for two years.

The NBER defines a recession as "a significant decline in economic activity spread across the economy, lasting more than a few months".

It bases its assessment on final figures on employment, personal income, industrial production and sales activity in the manufacturing and retail sectors.

Merrill Lynch said that the figures showing the jobless rate hitting 5% in December were the final piece in that puzzle.

"According to our analysis, this isn't even a forecast any more but is a present day reality," the report said.
