NEW YORK, March 22 (Reuters) - Oil rose on Tuesday as unrest in Yemen threatened to further crimp energy exports from the Gulf region and the U.S. dollar weakened to a 15-month low on recovering risk appetite among investors.
French oil giant Total <TOTF.PA> warned buyers of liquefied natural gas from its Yemen LNG project that shipments from the country could face cuts due to escalating political unrest, although they remain normal for now. [
]Thousands of Yemeni protesters took to the streets on Tuesday, clamoring for President Ali Abdullah Saleh to step down. Several top officials have already abandoned Saleh, who warned on Tuesday that his country would descend into civil war if he were forced to quit. [
]A bloody political standoff in Libya between the Muammar Gaddafi regime and rebels in control of the country's east has slashed oil production from the OPEC country by around 75 percent, to below 400,000 barrels a day (bpd). [
]Yemen pumps around 290,000 bpd of oil, largely for export, and ships 0.9 billion cubic feet per day of LNG, about 9 percent as much as top LNG exporter Qatar.
BULLISH FOR OIL
"The situation in the Middle East is still very bullish for oil," said Phil Flynn, analyst at PFGBEST Research in Chicago. "The unrest spreading (there) on top of the conflict in Libya is still the market focus."
Brent crude futures <LCOK1> rose 86 cents to $115.82 a barrel as of 12:23 p.m. EDT. U.S. crude futures for April <CLc1> rose $1.55 a barrel to $103.88 in light volume as the contract neared expiration on Tuesday. The more active May contract <CLK1> traded up $1.24 a barrel to $104.33.
U.S. crude had earlier fallen as low as $101.43 after Japan said it would release oil from its strategic stockpiles following the recent earthquake and tsunami which forced the idling of nuclear reactors and led to power outages. [
]The outages should lead the Asian country, the world's No. 3 crude importer, to boost oil-fired power generation, increasing oil demand, Goldman Sachs said on Monday. [
]The U.S. dollar <.DXY> slumped to a 15-month low against other major currencies as a resumption in risk appetite spurred demand for currencies and commodities that could offer higher returns. [
]Oil inventories in top consumer the United States likely rose for a third consecutive time last week, gaining 2 million barrels on higher imports, according to a Reuters poll of analysts ahead of stocks data to be released Wednesday by the U.S. Energy Information Administration. [
]Iraq's oil minister said OPEC is counting on oil prices stabilizing around 30-month highs near $120 a barrel.
That $120 oil price range is an "acceptable" level that would not hinder global growth, minister Abdul-Kareem Luaibi said. [
]ESCALATING UNREST
Adding to oil supply concerns were risks that unrest could spread to bigger oil producers that have so far not faced major upheaval, including Saudi Arabia, the world's leading oil exporter and Yemen's northern neighbor.
"An unstable Yemen is always a headache for the Saudis and a refugee crisis would become a significant problem," said Samuel Ciszuk, Middle East analyst at IHS in London.
"Not the least as Islamic militants would take the chance to blend in and enter the kingdom."
Protests also grew on Tuesday in Syria, where hundreds of people marched in southern towns for a fifth day and the government arrested an opposition figure. [
].Tensions also flared in Gaza, where Israeli tank fire killed four Palestinians. [
]The chief executive of U.S. independent refining company PBF Energy, Tom O'Malley, said he expects political unrest to spread further into major Middle Eastern oil-producing nations.
"In my opinion, no one is going to be spared," O'Malley told a refining conference in Texas. "We might see disruptions in the really big producing areas."
