NEW YORK, Feb 19 (Reuters) - U.S. stocks rose on Tuesday as earnings from top retailer Wal-Mart Stores Inc eased worries about U.S. consumer spending and energy shares jumped as the price of crude oil shot to a one-month high above $98 a barrel.
Stocks climbed to a two-week high in Japan and elsewhere in Asia but European shares ended little changed as a relatively reassuring update from Barclays <BARC.L> was offset by a shock $2.85 billion write-down at Credit Suisse on its asset-backed investments.
Safe-haven U.S. government bond prices fell as the rising U.S. equity market indicated an increased tolerance for risk among investors. But euro-zone government debt rose on the new wave of bank write-downs in Europe.
Shares of Exxon Mobil <XOM.N> and Chevron Corp <CVX.N>, whose stock debuted on Tuesday as a component of the Dow Jones industrial average, gained more than 2 percent. Shares of Wal-Mart <WMT.N>, the world's largest retailer, rose 1.5 percent.
"You've had a big move in oil over the last few days. We're almost back to $100 a barrel and that's what drives most things up," said Stephen Massocca, co-chief executive of San Francisco-based investment bank Pacific Growth Equities.
"Wal-Mart wasn't a disaster. It was moderately good news."
Shortly before 1 p.m., the Dow Jones industrial average <
> was up 88.49 points, or 0.72 percent, at 12,436.70. The Standard & Poor's 500 Index <.SPX> was up 1.13 points, or 0.08 percent, at 1,349.99. The Nasdaq Composite Index < > was down 10.74 points, or 0.46 percent, at 2,321.80.Barclays was the first major UK bank to report results after a turbulent year, and analysts said Tuesday's numbers -- including a modest $584 million increase in write-downs and a 10 percent dividend increase -- bode well for the sector.
Analysts said other banks would unlikely report further losses from earlier disclosures, easing investor concerns.
"The fact that (Barclays) felt confident enough to declare an increase in the dividend really stabilized the situation," said Edward Menashy, an economist at Charles Stanley.
Shares of other European banks also gained, with HSBC <HSBA.L> up 0.4 percent and Royal Bank of Scotland <RBS.L> rising 1.6 percent.
In Japan, stocks climbed to a two-week high as Mitsubishi UFJ Financial Group <8306.T> and other banks gained, spurred by a report that Qatar has bought shares in Credit Suisse and plans to spend as much as $15 billion on European and U.S. bank stocks over the next year.
The benchmark Nikkei <
> hit 13,853, its highest level since Feb. 5, before paring gains to close 0.9 percent higher at 13,757.91.OIL UP ON SUPPLY WORRIES
Oil extended four days of gains, rising to a month-high, on expectations that supplies will be tight. The market is on edge over a quarrel between OPEC producer Venezuela and Exxon, the world's largest non-government-controlled oil company by market value.
Prices began to rally last week after Venezuela cut exports to Exxon but stopped short of a wider disruption to the United States, the world's biggest oil consumer.
U.S. light sweet crude oil <CLc1> rose $2.79, or 2.92 percent, to $98.29 per barrel.
The Organization of Petroleum Exporting Countries is unlikely to cut output at its March 5 meeting due to rising prices and uncertainty about Venezuelan and Nigerian supply, OPEC delegate sources said Tuesday. [
]That was after OPEC President Chakib Khelil, Algeria's oil minister, told Reuters "production is not going to increase. It will either decrease or be stable." [
]The high-yielding Australian and New Zealand dollars climbed as investors added to risky trades amid strong gains in commodity prices and expectations of further interest rate increases in Australia.
The Aussie rose to three-month highs versus the greenback after minutes from the Reserve Bank of Australia's February policy meeting cemented expectations for more interest rate hikes, boosting the currency's appeal to global investors.
The dollar was down against a basket of major trading-partner currencies, with the U.S. Dollar Index <.DXY> down 0.22 percent at 75.925 from a previous session close of 76.095.
