NEW YORK, Feb 11 (Reuters) - Bargain hunters pushed U.S. stock prices up on Wednesday, while gold shot to a six-month high and the dollar gained versus the yen as investors gave a cold shoulder to the U.S. government's revamped bank rescue plan.
U.S. and euro zone government debt prices rose as worries about the effectiveness of the plan unveiled on Tuesday by U.S. Treasury Secretary Timothy Geithner bolstered their safe-haven appeal.
The interbank cost of borrowing dollars over three months inched up as the outlook for the health of financial markets remained murky in the eyes of investors after Geithner failed to supply sufficient detail to calm widespread skittishness.
Gold jumped 3 percent to its highest level since last July and European stocks lost ground, ending at their lowest level in a week.
"There was a lot of disappointment behind the package, either because the measures weren't concrete enough or because they thought they hadn't tackled the root cause of the problem," said BNP Paribas analyst Michael Widmer.
"A lot of investors reassessed the risk in the market, and as risk aversion increased, it helped prices," said Widmer, referring to the steady rise in gold prices during the session.
Spot gold prices <XAU=> rose $27.45 to $943.70 an ounce.
Investors bought U.S. financial shares that had been beaten down on Tuesday by double-digit stock losses as worries about efforts to shore up the battered U.S. banking system failed convince.
Shares of JPMorgan <JPM.N> climbed 6.3 percent, making the stock the top boost to the Dow, while Citigroup <C.N> added 7.2 percent. The S&P financial index was up 4.7 percent, after an 11 percent slide on Tuesday, and the KBW Banks index <.BKX> advanced 5.4 percent, after Tuesday's nearly 14 percent slide.
The financial sector also got a boost from Marsh & McLennan Cos Inc <MMC.N> after the No. 2 global insurance broker posted a better-than-expected fourth-quarter profit and forecast higher profits in 2009. The stock jumped 14.3 percent.

"As long as we don't get signals that the bottom has been reached for consumer spending and on investment spending, stocks will remain very volatile and stuck in a bear market," said Alexandre Iatrides, a fund manager at KBL Richelieu.
The dollar rose against the yen in choppy trading as investors locked in gains made by the Japanese currency on Tuesday. But the dollar's gains were limited by anxiety about the final size and scope of the U.S. recovery efforts.
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.47 percent at 85.965.
The euro <EUR=> was down 0.22 percent at $1.2868. Against the yen, the dollar <JPY=> was up 0.37 percent at 90.63.
"The new administration has promised to do so many things but there hasn't been enough concrete evidence that they're doing enough to help this economy," said Steven Butler, director of foreign exchange trading at Scotia Capital in Toronto.

Oil pared earlier gains to fall toward $37 a barrel after government data showed that U.S. crude oil stockpiles rose more than expected last week on low demand from refineries.
"We have a glut of oil here in the United States and any OPEC cuts that we are seeing are not enough to keep up with the decline in demand," Mike Zarembski, senior commodities analyst at optionsXpress in Chicago.
