NEW YORK, Jan 9 (Reuters) - The dollar rebounded on Wednesday on technical buying, but a speech by the Federal Reserve chief and key central bank meetings on Thursday confined trading to tight ranges.
Sterling hit a record low against the euro and a nine-month trough against the dollar as renewed fears about the British retail sector stoked expectations of a UK interest rate cut.
Overall, currency investors remained focused on the U.S. equity market, typically a barometer of risk aversion. Wall Street is off to its worst start in history as investors fear the U.S. economy is sliding into a recession.
The S&P 500 has fallen more than 5 percent for its poorest showing in the first five days of a year dating back to the index's launch in 1926, according to Reuters data.
"Certainly equity markets will drive currencies today." said Adam Fazio, currency strategist at CIBC World Markets in New York.
He added that price action in the market has been confined to narrow ranges ahead of key events this week. "In dollar/yen, 110 remains a big level and we were never able to get through that."
In early New York trading, the dollar was up 0.3 percent against a basket of six major currencies at 76.302 <.DXY>, in large part thanks to a 0.3 percent rise against the yen to 109.23 yen <JPY=>, pulling away from a six-week low of 107.86 yen on Friday, according to Reuters data.
Traders covered their short dollar positions ahead of a speech by Fed chief Ben Bernanke on Thursday.
It will be Bernanke's first public remarks on the economy this year. Recent grim U.S. manufacturing and employment data have intensified the threat of recession and likelihood the Fed will cut rates by half a percentage point later this month.
"If the dollar can't weaken on dovish or pessimistic comments from Bernanke, then I think that would be a very important price signal," said Paul Mackel, senior currency strategist at HSBC in London.
"You should be cautious about getting overly short the dollar at current levels. Maybe short-term dollar positions are (ripe) for squeezing."
The euro was down 0.2 percent against the dollar at $1.4676 <EUR=>, but was up almost 0.4 percent against the UK pound at 74.86 pence <EURGBP=>, having reached a record post-1999 launch peak of 74.99 pence.
Sterling fell 0.6 percent against the dollar to $1.9602 <GBP=>, trading as low as $1.9587, a low not seen since late March.
Sterling was hit after Marks & Spencer <MKS.L>, Britain's largest clothing retailer, reported much weaker than expected sales during the final three months of last year, sending its shares plummeting as much as 20 percent.
UK rate futures tilted toward pricing a 60 percent chance from around 50-50 that the Bank of England will cut rates a quarter point to 5.25 percent on Thursday.
The European Central Bank will also hold a monetary policy meeting on Thursday, although markets expect the central bank to hold interest rates steady at 4.0 percent. Still, markets will be closely watching comments from ECB President Jean-Claude Trichet, given a spate of weak economic euro zone numbers.
In the United States, markets are pricing in as much as a 70 percent chance that the Fed will slash interest rates by a hefty half-point later this month to 3.75 percent. They see rates down to 3 percent or lower by the end of the year. (Additional reporting by Jamie McGeever in London; Editing by Tom Hals)
