NEW YORK, Dec 2 (Reuters) - The U.S. dollar fell against the euro and a basket of currencies on Tuesday as a rebound in stock markets encouraged investors to emerge from the shelter of U.S. assets.
U.S. and European stocks <
> rose, which weighed on the yen, although investors remained apprehensive as they braced for dramatic interest rate cuts later in the week.The U.S. and Japanese currencies have found support in recent months as investors cut exposure to riskier assets financed by cheap yen and dollar loans. U.S. portfolio investors have also moved funds back to their domestic market, which has also boosted the greenback since August.
"There seems to be reduced risk aversion in the market because of the rally in equities and that has pressured the dollar against the euro and weighed on the yen," said Matthew Strauss, senior currency strategist, at RBC Capital Markets in Toronto.
"But this doesn't mean that investors are willing to get on risky trades again. We are still in a period of extreme uncertainty. I still believe the strong dollar trend is still in place given that the euro has never been able to sustain gains above $1.27."
In early New York trading, the euro rose 0.5 percent against the dollar to $1.2691 <EUR=> and gained 0.9 percent versus the yen to 118.70 <EURJPY=>.
The ICE Futures' dollar index <.DXY>, a gauge of the greenback's value against six major currencies, weakened 0.5 percent to 86.620.
The dollar <JPY=> rose 0.3 percent against the yen to 93.48 It fell as low as 92.64 yen earlier, the lowest since Oct. 28, according to Reuters data..
GLOBAL RATES IN FOCUS
Risk appetite also improved, analysts said, after the Bank of Japan held an emergency policy meeting on Tuesday and announced it will accept a wider range of corporate debt as collateral in money market operations to help unfreeze credit markets. For details, see [

An unexpectedly bold 100 basis point cut from the Reserve Bank of Australia had earlier kept the Australian dollar under pressure, although the currency has since recovered with the rise in stocks. The Australian dollar rose 0.4 percent versus the greenback to US$0.6425 <AUD=>.
The RBA's move has raised expectations other central banks may follow suit with aggressive easing in Britain, the euro zone, Sweden and New Zealand this week to revive their flagging economies. That should further support the U.S. dollar as the rate cuts would shrink the yield advantage of currencies such as the euro and sterling.
A steep slide in the yuan to the bottom of its trading band against the dollar has also boosted the U.S. currency, analysts said, because it fueled speculation China may be shifting its forex policy to allow a weaker yuan to stimulate the economy.
In other currencies, sterling rose 1 percent to $1.5051 <GBP=>, despite the view that the Bank of England will slash rates by as much as 100 basis points on Thursday, one month after chopping them by 150 basis points to 3.0 percent.
Also on Thursday, the European Central Bank is seen cutting rates by at least 50 basis points from 3.25 percent and possibly more. Market participants, meanwhile, expect the Reserve Bank of New Zealand to cut rates by 100 basis points or more from 6.5 percent.
Brown Brothers Harriman believes that much like the Federal Reserve, other central banks, with little room to cut rates, such as the Swiss National Bank, may have to resort to quantitative measures to ease monetary policy.
"Such steps may not have an immediate impact on the currency markets but do indicate central banks are not out of ammunition," said the U.S.-based investment bank. (Additional reporting by Naomi Tajitsu in London; Editing by Tom Hals)
