* Investors still inclined to reduce risk exposure

NEW YORK/LONDON, May 26 (Reuters) - Bargain-hunting lifted U.S. stocks at the open on Wednesday, but the euro fell against the dollar for a third straight day as U.S. Treasury Secretary Timothy Geithner urged European leaders to find a unified approach to the region's deepening debt crisis.
The euro slid against the dollar but stayed above the 8-1/2 year lows hit on Tuesday. Oil prices rallied nearly 4 percent, climbing back above $71 a barrel after a U.S. industry report showed a steep drop in gasoline stockpiles. [
]"There is still a deeply negative sentiment toward the euro due to the debt situation in Europe, the issue with Spain over the weekend and how investors are bracing for the possibility that other banks in the region may follow suit and may need a bailout," said Joe Manimbo, senior market analyst at Travelex Global Business Payments in Washington.
Spain took over a small savings bank, CajaSur, over the weekend, and analysts said the move highlighted weakness in the European banking sector.

U.S. Treasury Secretary Timothy Geithner urged Europeans on Wednesday to work for a globally consistent approach to financial reform as the European Union said it might go it alone with a plan to tax banks to pay for future rescues. [

Geithner's stress on coordination of new regulation appeared aimed chiefly at Germany, Europe's biggest economy, which stunned markets and angered its European Union partners by unilaterally banning some speculative financial trades last week. [

"We now have five quarters of increases, and that's a good sign of transitioning from a recovery to sustainable growth," said John Canally, investment strategist and economist at LPL Financial in Boston.
"It's too early to gauge the impact of the European crisis ... (we) probably have to wait until May or even July to see an impact."
The rise in risk appetite hurt Treasuries, and the 30-year bond <US30YT=RR> shed 36/32 in price, with its yield rising to 4.14 percent from 4.08 percent late on Tuesday. The benchmark 10-year note <US10YT=RR> was trading 25/32 lower in price to yield 3.25 percent, up from 3.18 percent.
While investors watched stocks, Treasuries prices were also undermined by traders looking for price concessions ahead of the auction of $40 billion of five-year notes on Wednesday afternoon.
"Risk trades seem to be in a better mood today," said Andrew Brenner, managing director at Guggenheim Partners in New York.
