* China GDP and CPI figures match expectations
* Keeps speculation for yuan revaluation intact
* Commodity currencies hold near recent highs vs dollar, yen

TOKYO, April 15 (Reuters) - The dollar stayed on the defensive on Thursday while commodity currencies like the Aussie held firm after data reinforced views that China's economic growth was accelerating and Beijing may soon revalue its currency.
But the reaction was mostly subdued as the results matched those indicated previously by sources, traders said.
China's economic growth accelerated in the first quarter to 11.9 percent, the fastest annual pace in nearly three years, and consumer price inflation in March was 2.4 percent year-on-year, decelerating from February's 2.7 percent rate.[
]"There was nothing new to trade on as they matched exactly the previously reported numbers and supported optimistic views on the economy," said a senior prop trader for a big Japanese bank.
"But the Aussie and cross yen are staying unexpectedly firm without any major corrective moves downward even after rising earlier on expectations for the Chinese data. That makes me wonder what could possibly trigger liquidation of positions in these currencies next."
As the world's third-largest economy continues to gather steam, speculation is growing that China may be preparing to slightly loosen its grip on the yuan.
Investors have trimmed long positions in the U.S. dollar after Singapore effectively revalued its currency <SGD=D4>, which also fueled speculation China may allow the yuan to appreciate.
Any move by China to revalue is seen to be positive for Asian currencies and could weigh on the U.S. dollar in the short term.
The dollar index <.DXY> was flat at 80.231, while a break below 80 risks a test of its mid-March low near 79.50.
China is the single largest buyer of Australian commodity exports and its insatiable demand has been driving huge price increases for coal and iron ore.
The Australian dollar <AUD=D4>, which climbed 0.7 percent on Wednesday, edged down 0.1 percent to $0.9346. It faces some solid resistance at $0.9407, its high for 2009 set last November.
It was flat against the yen after earlier edging up near this week's 19-month high at 87.55 yen <AUDJPY=R>.
The dollar rose 0.2 percent to 93.36 yen <JPY=>, capped at about 93.50 by Japanese exporter selling and by options-related hedging, traders said.
Dealers say the market is also reluctant to take aggressive positions in dollar/yen and yen crosses just now because it's not clear how the yen would react if China were to revalue.
Some think the yen would rise sharply against the dollar if China allows the yuan to appreciate.
But others wonder if the yen's weakness after Singapore tightened this week may be a sign that a yuan move would be a cue for risk-on trades -- which tend to dent the low-yielding yen and support growth-linked currencies such as the Aussie.
LOW FOR SOME TIME
Adding to the dollar's earlier soft tone were comments by Federal Reserve Chairman Ben Bernanke that U.S. interest rates will stay low for some time. [

"We were looking for U.S. growth to surprise on the upside but that is now mostly priced in. The DXY looks like a 79-82 range trade for the time being but we still strongly favour a topside break," it said.
The index fell through its 55-day moving average on Wednesday and closed below the 23.6 percent Fibonacci retracement of its rally from 74.50 in late November to its March peak above 82.00.
The euro <EUR=> slipped 0.1 percent to $1.3640, after rising nearly 0.4 percent on Wednesday, helped by short covering. But worries about Greece and increased scepticism about the bailout package are likely to limit the upside.
The yen was also hurt early by renewed demand for riskier assets like stocks, although it clawed back some ground later in the Asian day. Strong U.S. corporate earnings and some robust economic data also boosted sentiment.
Sterling pushed to its highest level since late February at $1.5520 <GBP=D4>, with talk of buying interest on sterling/yen to try to trigger loss-cutting buy orders and push it through resistance at 145 yen.
It touched 145.04 yen <GBPJPY=R>, two-month high, with polls showing the opposition Conservatives extending their lead over the ruling Labour party ahead of May 6 elections. [
