NEW YORK, Feb 5 (Reuters) - The euro fell against the dollar on Thursday as the European Central Bank warned that the euro zone was undergoing an extended downturn, although it stood pat on interest rates as widely expected.
ECB President Jean-Claude Trichet had previously hinted that markets should not expect a rate move at this meeting but signaled on Thursday that the central bank may resume its monetary easing cycle in March.
He also said at a press conference that zero interest rates were not something the bank considered "appropriate," and that helped limit euro losses. For details, see [
]In the United States, a report showed weekly jobless claims jumped to a 26-year high last week, another sign of deterioration in the labor markets. [
]The news boosted the dollar's appeal as a haven amid a global downturn, analysts said.
The jobless report is "pretty ugly. Clearly risk is off the table. And this has hurt the euro against the dollar because risk-aversion flows are going once again into the dollar," said Boris Schlossberg, director of currency research at GFT, New York. "The economy clearly is in desperate need of a stimulus."
In mid morning trading in New York, the euro was 0.3 percent lower at $1.2795 <EUR=>, after trading as low as $1.2760, according to Reuters data. The dollar was 0.4 percent higher at 89.84 yen <JPY=>.
In another economic news, the government said new orders received by U.S. factories slumped by a greater-than-expected 3.9 percent in December. [
]"It's the fifth consecutive month of decline ... it's certainly not a positive and it won't help to contribute to any pick-up in risk appetite," said Terri Belkas, a currency strategist at DailyFX.com in New York.
BOE CUT RATES
The euro also fell against sterling which surged after the Bank of England cut rates by 50 basis points. The BoE's rate decision put UK interest rates at 1.0 percent compared with euro zone rates at 2.0 percent.
The euro was last 1.6 percent lower at 87.36 pence <EURGBP=>.
"The Bank of England's proactive cuts come in contrast with the ECB's diffidence and this will continue to drive EUR/GBP lower from current levels," Geoffrey Yu, a currency analyst at UBS AG said in a note. "
Traders said the euro also remained vulnerable to credit woes in Russia and eastern Europe.
Russia said on Thursday it would increase stakes in state banks in coming months. On Wednesday, rating firm Fitch downgraded Russia's sovereign ratings while Kazakhstan central bank's decided to devalue its currency.
"The euro has massive problems given the region's association with eastern European emerging markets as there are big Italian and German banks with large exposure there," said Maurice Pomery, a currency strategist at IDEAglobal in London.
