NEW YORK, March 5 (Reuters) - The dollar firmed against most currencies on Thursday, as fear gripped the market after stocks dropped amid worries about General Motors and the fate of U.S. banks, attracting bids for the greenback as a safe haven.
The U.S. currency, however, fell against the yen, after earlier touching a four-month high near 100 yen, temporarily re-establishing its link with the stock market's performance.
The pair's correlation with equities broke down recently as investors sold the yen despite slumping stocks, as Japan's economic recession weighed on market sentiment.
But weakness in U.S. stocks overshadowed interest-rate cuts by the Bank of England and European Central Bank earlier, which also helped push the euro and sterling lower versus the dollar. See [

"Plus, we've got more bad news coming tomorrow with the non-farm payrolls report," he said, adding that it's hard to see any silver lining for the economy right now.
In early afternoon trading, the euro fell 0.7 percent to $1.2552 <EUR=> after earlier hitting session lows at $1.2483.
But the dollar fell 0.8 percent to 98.33 yen <JPY=> as traders took profits after the greenback's earlier rise to 99.67 yen, its highest level since early November.
Worries about Japan's economy, which contracted sharply in the fourth quarter as exports plummeted, are expected to limit yen gains, though. Brian Kim, a currency strategist with UBS in Stamford, Connecticut, said he expects the dollar to renew its assault on 100 yen in the days ahead.
CHINA DISAPPOINTMENT
Markets were also disappointed that Chinese Premier Wen Jiabao, in his annual speech to the National People's Congress overnight, did not make an announcement about adding to the original 4-trillion-yuan stimulus package introduced in November. See [
]."That dampened market sentiment overall," Forex.com's Dolan said.
Global markets had soared while the dollar had fallen versus the euro on Wednesday on speculation Wen would add to the stimulus plan unveiled in November.
Earlier in the session, the euro dipped below $1.25 after the ECB cut rates by a half-percentage point to a record low and said the 16-nation euro-zone economy may shrink up to 3.2 percent in 2009.
ECB President Jean-Claude Trichet did not rule out additional moves on interest rates, suggesting borrowing costs may yet fall below their current 1.5 percent.
Sterling fell 0.2 percent to $1.4130 <GBP=> after the Bank of England cut interest rates to a record low and said it would start buying 75 billion pounds ($106 billion) of assets to boost the UK economy.
Unlike the BoE, the ECB did not give any clear hints about quantitative easing plans, but Trichet's warning that rates could still fall further kept pressure on the common currency.
With the ECB and BoE rate decisions out of the way, analysts are now focusing on the U.S. non-farm payrolls report due on Friday. Analysts are expecting U.S. job losses of 648,000 in February, according to a Reuters poll, with some forecasting job cuts as high as 800,000.
Yet some analysts such as Kathy Lien, director of FX research at GFT, think the market could be up for a positive surprise on the jobs report. Lien said the level of job losses could be less than 600,000.
She cited the rebound in the employment component of the service sector index provided by the Institute for Supply Management.
"Over the past 10 years, there has been an 82 percent positive correlation between non-farm payrolls and the employment component of the service sector report," she said. (Additional reporting by Steven C. Johnson; Editing by Jan Paschal)
