LONDON/SINGAPORE, Jan 10 (Reuters) - Oil traded around 1 percent higher on Monday after a leak shut an Alaskan pipeline that carries 12 percent of U.S. crude output, but gains were capped by a stronger dollar due to worries about Portugal's debt.
The Trans Alaska Pipeline was shut down on Saturday because of a leak in Prudhoe Bay, forcing oil companies to cut output to 5 percent of their daily average of 630,000 barrels. [
]The shutdown of one of the key U.S. oil arteries sent crude prices leaping early in Asia by almost $2 to $89.98 a barrel, although prices eased to $88.87 at 1330 GMT.
"Of course a pipeline with a magnitude like that is supportive for crude prices. It is normal that first the market reacts a bit too much. But then it is a question of how long the line will be closed," said Hannes Loacker, an oil analyst at Raiffeisen Bank International.
"It is of course a problem for North America, but it wouldn't justify a price increase by 2 or 3 percent ... Today most (financial) markets are facing some minor losses. So this is like the other side of the coin," Loacker added.
"This adds to what happened in the Gulf of Mexico at a time when U.S. regulators are still looking at regulations around oil drilling," said Ben Westmore, a commodities analyst at National Australia Bank.
"Events like this carry risks around future regulation that could dramatically reduce supply on a more permanent basis than this temporary outage. There is a possibility the risk is pretty substantial for the (oil futures) market." <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For a list of incidents at the pipeline: [

Traders said that if the outage lasted longer than a week or two, it has the potential to be very bullish. One noted that most of the pipeline's previous problems had been fixed quickly, but in the post-Deepwater Horizon world, approvals to restart could take longer after accidents.
"An extended shutdown should have a price positive impact on Brent before (U.S. crude) WTI due to the location of the US supplies being affected," said Olivier Jakob from Petromatrix.
Gains in Brent crude <LCOc1> were in line with gains in U.S. crude as it rose 78 cents $94.07, keeping Brent's premium to WTI at $5.4 or close to a seven-month high.
Iran, holder of the rotating OPEC presidency, said on Monday it was comfortable with the rising oil price and there was no need for any emergency OPEC meeting. [

].On the foreign exchange front, the euro hovered near four-month lows against the dollar on Monday on mounting worries about Europe's debt crisis, after a source said Portugal was under growing pressure to accept EU/IMF aid.
A senior euro zone source told Reuters on Sunday that pressure was growing on Portugal from Germany and France to seek financial help from the European Union and International Monetary Fund to prevent the bloc's debt crisis spreading. [
]Traders said the European Central Bank threw Portugal a temporary lifeline by buying up its bonds [
]The dollar index against a basket of currencies <.DXY> was up 0.1 percent at 1344 GMT, capping gains in oil prices.
Technically, oil still looked weaker and oil will end the current rebound and fall back to Friday's low at $87.25 as a downward wave "C" has not been completed, according to Reuters technical analyst Wang Tao said. [
