NEW YORK, Nov 2 (Reuters) - The Australian dollar raced to a 28-year high against the greenback on Tuesday after a surprise Australian interest rate hike, while the U.S. currency fell ahead of a Federal Reserve meeting expected to produce a fresh round of monetary easing.
The euro traded above $1.40, buoyed by a pick-up in the euro zone manufacturers' output. For more see [
].Traders, however, were skeptical that the euro will be able to sustain gains above this level given uncertainty surrounding the Fed's decision on Wednesday and the renewed escalation in sovereign debt worries.
The Reserve Bank of Australia, meanwhile, raised its cash rate by 25 basis points to 4.75 percent as a preemptive strike against inflation. That highlighted the contrast with the Fed which is widely seen as easing policy further on Wednesday to help revitalize the U.S. economy and extended the differential between the two economies' two-year yields to their widest since early 2008. Benchmark U.S. rates are close to zero.
Omer Esiner, chief market analyst at Commonwealth Foreign Exchange, said Australia's rate hike along with better-than-expected economic data out of the United States, Britain, and China the last few days have increased optimism about the global economy and revived risk appetite,
"We're seeing elevated stocks, commodities, and stronger performance of higher-yielding assets. From a global perspective, the growth outlook looks solid and that's feeding some appetite for risk," Washington-based Esiner said.
In mid-morning trading, the dollar index <.DXY> was down 0.8 percent at 76.669 against a currency basket. The Australian dollar traded 1.3 percent higher on the day at US$1.0011, with near-term gains seen limited by stop-loss orders around $1.0015. It hit a peak of US$1.0025 <AUD=D4>, the highest since the currency was floated in 1983.
FOCUS REMAINS ON FOMC
The euro <EUR=EBS> gained 1.1 percent to $1.4041, with talk of demand of a semi-official European name helping boost the European single currency.
Aside from the RBA rate hike, the flavor of the day remains the Federal Open Market Committee, which starts its two-day meeting on Tuesday and looked close to embarking on a second round of monetary easing. [
]Markets generally expect the Fed to commit to buying at least $500 billion in Treasury debt in the coming months. Much uncertainty surrounds the scope and pace of purchases, however, leaving the dollar vulnerable to choppy moves in prevailing ranges.
Robert Lynch, senior currency strategist at HSBC in New York, suggested that if the Fed meets the market's expectations, the negative impact on the dollar may not be all that dramatic as the currency's decline since the summer seemed to price in much of that outcome.
He added that the "anticipation of the Fed outcome in the run-up to Wednesday's announcement is more likely to work against, rather than for, the dollar."
Investors were also keeping an eye on the results of U.S. mid-term elections being held on Tuesday. Polls continue to indicate Republicans will take over the House of Representatives, close the gap on Democrats' lead in the Senate and take over a majority of the country's governorships.
Some analysts have said this could be positive for the dollar since the Republicans were running on a campaign of fiscal austerity and reduced government regulation.
HSBC's Lynch, however, said that is a "gross oversimplification of what could actually happen."
But he pointed out that in an "environment where there is already a good amount of bad news priced into the dollar, we would not dismiss the potential for those sentiments to work to the currency's advantage in the coming days, providing it is not countered by the Fed and upcoming U.S. economic data."

The dollar edged up 0.2 percent to 80.66 yen <JPY=>, though it was still close to the record low of 79.75 yen set in 1995. The risk of Japanese intervention to weaken the yen was expected to mount if the dollar slips below 80 yen. (Additional reporting by Naomi Tajitsu in London; Editing by James Dalgleish)
