NEW YORK, Sept 23 (Reuters) - The dollar firmed slightly but remained near a one-year low against a basket of currencies on Wednesday as investors braced for the end of a Federal Reserve meeting expected to keep U.S. interest rates at record lows.
Dealers were on alert, though, for signs that the Fed may curtail some of the programs that over the last year have injected trillions of dollars into the troubled banking system, and that was keeping exchange rate moves somewhat subdued. For details see [
]."People are watching for tweaks to their current programs, which would be market-moving, but I don't think they want to rattle the markets right now," said Jacob Oubina, senior currency strategist at Forex.com in Bedminster, New Jersey.
Traders were also keeping an eye on a Group of 20 summit, which begins on Thursday and is expected to call on countries to maintain economic stimulus plans, a move which could give a boost to riskier assets. [
].The dollar index <.DXY>, which measures the dollar's value against a basket of six other major currencies, was marginally higher at 76.219, off an earlier low of 75.892, a level not seen since last September.
The dollar has shed 2.5 percent this month, though market strategists warned that any hints from the Fed about future exit strategies could squeeze large short dollar positions.
The euro pulled back a bit from a one-year high above $1.48 as U.S. stocks turned negative and was down 0.1 percent at $1.4768 <EUR=>. Sterling rose 0.3 percent to $1.6407 <GBP=> and the dollar rose 0.3 percent to 91.42 yen <JPY=>.
News from other central banks showed policymakers are at least thinking about exit strategies, even if they're not ready to implement them.
Minutes from the Bank of England's last meeting showed officials did not press to increase asset purchases, while the dollar shed 1 percent against the Norwegian crown <NOK=> after the Norges Bank left rates unchanged but said it had considered raising them. [
].The New Zealand dollar hit a 13-month high after data showed the economy unexpectedly exited recession in the second quarter. It was last up 0.5 percent at $0.7224 <NZD=>.
The Bank of Canada reiterated its pledge to keep interest rates on hold until mid-2010 but said rates could rise beyond that, while the European Central Bank's Axel Weber said there was no need to alter current monetary policy yet. [
] and [ ]G20 IN FOCUS
Matthew Strauss, senior currency strategist at RBC Capital Markets in Toronto, said he expects currency issues to be "very low on the list" of things to discuss for G20 policymakers.
Speculation that the G20 would focus on rebalancing the global economy, a process that almost certainly calls for a weaker dollar, also hit the U.S. currency on Tuesday.
But Citigroup strategists said the exchange rate adjustment that requires the dollar to weaken and the currencies of high surplus countries, such as Japan and emerging markets like China, to appreciate has been going on for some time.
They said G20 efforts are likely to focus instead on diminishing the role of U.S. consumption in the world economy, reducing Asian savings and boosting European demand.
In an interview on CNBC late Tuesday, Canadian Prime Minister Stephen Harper echoed that sentiment, saying, "We cannot hinge future growth simply on an overextended American consumer." [
