* MSCI world equity index rises from 3-month lows
* Australia surprises by holding interest rates unchanged (Updates with data, comment, dateline, byline)

NEW YORK, Feb 2 (Reuters) - Upbeat U.S. earnings and economic data plus Australia's decision to hold interest rates rippled through global markets on Tuesday, lifting stocks from 3 month lows and boosting commodity prices.
Gains were capped by ongoing worries over potentially tougher U.S. banking regulations while investors waited for the European Commission's recommendations on Greece's fiscal reform plans on Wednesday before making big trading moves.
At 12:51 p.m. EST (1751 GMT), the MSCI world equity index <.MIWD00000PUS> was up 1.17 percent at 288.53. In the U.S. market, the Dow Jones Industrial average gained 0.82 percent, to 10,268.96 <
>, while the Standard & Poor's 500 stock index rose 0.94 percent, to 1,099.38 <.SPX>.Encouraging earnings reports from U.S. economic bellwether United Parcel Service <UPS.N> and industrial conglomerate Emerson Electric Co <EMR.N> helped fuel the U.S. rally.
"This whole earnings season is all about, 'Is there top-line growth,' and some companies are showing it," said Frank Ingarra, portfolio manager at Hennessy Funds in Stamford, Connecticut. "This will help us going forward because if companies grow their top line, they will hire some more employees to drive sales and orders."
Forward earnings per share ratios have dropped since the start of the year, from 15.6 percent to 13.8 percent, according to Thomson Reuters data. The compression could indicate either stock prices are not keeping up with earnings or investors priced in the improved corporate results.
Pending sales of U.S. homes edged up as expected in December, helping calm fears of renewed weakness in the troubled housing sector. [
]In Europe, share prices rose for a third straight day, boosted by mining companies who benefit from the Reserve Bank of Australia's surprise decision to hold its key cash rate steady at 3.75 percent, against expectations for a rise to 4.0 percent. [
]The pan-European FTSEurofirst 300 <
> index of top shares closed up 0.9 percent at 1,027.18 points.Crude oil prices <CLc1> rose 2.61 percent to $76.37 a barrel on hopes energy demand in China and the United States will grow. Spot gold <XAU=> gained $8.10 an ounce to $1,115.
DOLLAR WEAKENS
The euro advanced against the U.S. dollar, supported by an earlier narrowing in Greek government bond yield spreads over German debt as investors a waited the European Commission's reaction to Greece's plan.
Greek Prime Minister George Papandreou said the level of Greek and euro zone bond spreads was completely unjustified, keeping up the rhetoric against speculators he blames for targeting his country. [
] [ ]"Bond market fears over Greece reached a high last Thursday and have since fallen back," said Camilla Sutton, senior currency strategist at Scotia Capital in Toronto.
"This hints that the market is stabilizing and that much of the bad news is now priced in," Sutton said.
The premium investors demand to hold 10-year Greek government bonds over German Bunds initially fell to a session low of 326 basis points but ended the day up 23 bps to 359 bps, still well below last week's euro era highs of 405 bps.
The euro <EUR=> recovered from early losses to trade 0.19 percent higher on the day at $1.3954, recovering from a seven-month low hit on Monday.
The Australian dollar <AUD=> fell to a low of US$0.8780 before paring losses to trade at US$0.8849 after the RBA decision.
Against the Japanese yen, the dollar <JPY=> was down 0.28 percent at 90.37. Japan's benchmark Nikkei-225 stock index rose 1.6 percent, led by Toyota Motor Corp's <7203.T> 4.49 percent rise after announcing plans to fix millions of recalled vehicles.
Caution is likely to prevail with White House adviser Paul Volcker due to appear before the Senate Banking Committee later in the day to defend the administration's proposal to limit risk-trading by banks, which triggered a sell-off in equities when it was first unveiled last month. [
]According to testimony obtained by Reuters, Volcker will urge Congress to curb the risks taken by large banks to help prevent them from being treated as "too big to fail."
U.S. Treasuries were little changed ahead of Volcker's testimony. Benchmark 10-year Treasury note <US10YT=RR> prices were up 1/32. The yield, which moves inversely to price, was at 3.65 percent, down from 3.66 percent on Monday.
