* Global stocks rally as oil slides further; banks soar

NEW YORK, July 23 (Reuters) - Global stocks rose on Wednesday, driven by a strengthening dollar, sliding oil prices and a surge in bank stocks in anticipation of a bailout in the slumping U.S. housing finance sector.
Oil prices fell $4 a barrel to a six-week low after a U.S. government report reinforced the belief that high prices and economic turmoil will reduce the demand for fuel.
The sliding oil prices and rising stocks combined to cut the safe haven appeal for U.S. and euro zone government debt, pushing bond prices lower. Gold's appeal as a hedge against inflation lost some luster as well, as prices fell almost 3 percent.
The drop in oil and improving confidence in the heavily hit U.S. financial sector helped the dollar rally to a one-month peak against the yen and a two-week high against the euro.
The dollar later pared some gains versus the yen after a Federal Reserve survey of regional economic conditions showed activity slowed somewhat since the last report.
Investors snapped up shares and bonds of mortgage finance companies Fannie Mae <FNM.N> and Freddie Mac <FRE.N>, which would receive an emergency government lifeline under a bill President George W. Bush was expected to sign into law.
Concerns about the health of the two companies, which own or guarantee almost half of the $12 trillion in U.S. mortgage debt outstanding, had weighed on financial markets and dashed hopes for a quicker recovery in struggling housing market.
"Congress is planning on passing this housing bill today and the president said he was going to sign it," said Ronald Simpson, managing director of global currency analysis at Action Economics in Tampa, Florida.
"While it's not a fix to the problem, it certainly is going to allay some fears at least for the short term," he said.
Shares of Freddie Mac jumped 13 percent to $10.96, while Fannie Mae climbed 11.2 percent to $14.90.
Wall Steet trading was fueled by hedge funds buying financial shares and selling oil. This marked a reversal of a trend in place much of the year in which they were long oil and short financials. Some analysts attributed the trades to a recent clampdown by the Securities and Exchange Commission on certain types of short selling in 19 financial companies.
"A lot of hedge funds, particularly those involved in short trading had the long-oil/short-financials trade for some time," said Rick Meckler, president of investment firm LibertyView Capital Management in Jersey City, New Jersey.
"So once that trade started to reverse, it's provided particularly strong support even to banks that have had weak quarterly results."

Gold ended nearly 3 percent lower as the dollar surged and crude oil prices sank, denting gold's appeal as an alternative investment in times of financial stress.
A slide in oil prices soothed some of the inflation fears that have supported gold, while other commodities such as grains and base metals also slipped.
