* Yen falls on crosses as Intel improves risk appetite
* Dollar falls against Asian currencies after MAS move
* Fed's Bernanke to testify on economic outlook at 1400 GMT
By Charlotte Cooper
TOKYO, April 14 (Reuters) - The low-yielding yen fell on Wednesday as upbeat earnings from technology bellwether Intel boosted appetite for riskier currencies while policy tightening by Singapore helped send the greenback lower across the board.
The euro and the Australian dollar climbed against both the the U.S. and Japanese currencies, and the dollar index <.DXY> fell after the Monetary Authority of Singapore (MAS) tightened policy by effectively revaluing the Singapore dollar. [
]Markets took the move as a signal of the central bank's confidence in the economic outlook, as it also shifted policy to modest and gradual FX appreciation, and it revived speculation about when China might revalue the yuan.
The MAS decision also fed into positive risk sentiment already stoked by better-than-expected forecasts from Intel Corp <INTC.O>, which boosted technology stocks around the region, helping higher-yielding currencies and denting the yen. [
]"The dollar is being sold against Asia and that's extended to the majors," said Robert Ryan, FX strategist at BNP Paribas in Singapore.
"Risk-on is the order of day at least in Asia but I wonder how much the MAS influence will extend into Europe."
The euro climbed 0.3 percent on the day to 127.25 yen <EURJPY=R>, moving above its 100-day moving average at 127.03 yen and edging up towards resistance from a previous high at 128.
The Australian dollar gained 0.4 percent to 86.86 yen <AUDJPY=R>, although it remained short of a recent 18-month peak at 87.51 yen. The pound gained 0.3 percent <GBPJPY=R>.
The dollar fell 0.3 percent on the index measuring its performance against six other major currencies <.DXY> to 80.257. It breached its 55-day moving average at 80.49 and was nearing a one-month low set on Monday.
"The Sing reweighting of the basket and appreciation stance is having a big impact on dollar/Asia with a lot of selling across the board," said a senior trader at a European bank in Hong Kong.
Speculation about when China might revalue was going to stay, he said. "It's just going to come and go in intensity."
"What Singapore did this morning just increases the pressure on China because the rationale for Singapore to allow currency strength is similar for why China should de-peg. It's domestic reasons rather than just external pressure," he said.
BERNANKE TIME
The Australian dollar rose 0.3 percent to $0.9312 <AUD=D4>, pushing through a psychological barrier at $0.9300 but failing to top a five-month peak just below $0.9400 set on Monday.
The euro, which is still enjoying a rebound stemming from short-covering after a rescue package for Greece at the weekend, rose 0.3 percent to $1.3650 <EUR=>, although it too hasn't made it through a high set on Monday of $1.3692 and analysts said fiscal concerns about Greece had far from gone away.
The market is also awaiting a testimony by Federal Reserve Chairman Ben Bernanke on the economic outlook before the Joint Economic Committee of Congress. That is due at 1400 GMT.
Several Fed officials are also due to speak and the market will be watching for retail sales data due at 1230 GMT.
There has been speculation Bernanke might use the forum to talk about normalising the spread between the fed funds and discount rates but analysts said they expected him to reaffirm the Fed's current stance of "low-for-long" rates.
"It's not the right timing although markets might be sensitive to the retail sales numbers," said Tomoko Fujii, senior currency strategist at Bank of America Securities-Merrill Lynch.
"In case of upside risk some market participants may speculate for a change towards a hawkish tone but it's still too premature."
The dollar was flat at 93.25 yen <JPY=>, with talk of an options strike at around 93.20.
Japan's third largest life insurer, Meiji Yasuda Life Insurance Co., said it planned to boost its unhedged foreign bond holdings by 300 billion yen ($3.2 billion) this financial year, and cut its hedged foreign bond debt due to rising hedging costs. [
]Japanese life insurers are watching for when U.S. rates start to rise, a change which would push up hedging costs and could see some buy more unhedged bonds, a shift likely to weigh on the yen.
The New Zealand dollar <NZD=D4> bucked the trend and fell 0.3 percent to $0.7115, after data showed a drop in retail sales during February. The patchy set of data prompted the market to push back chances of an interest rate hike in coming months. (Additional reporting by Kaori Kaneko; Editing by Joseph Radford)
