LONDON, Jan 18 (Reuters) - Brent oil edged higher on Tuesday after OPEC stuck to its view there was ample supply on the market, while the International Energy Agency said economic recovery would spur a gradual rise in demand.
Gains were capped by the resumption of crude through the Trans-Alaskan pipeline, which could add to inventory levels in top oil consumer the United States.
Brent for March <LCOc1> added 42 cents to $97.85 a barrel by 1112 GMT. The front-month Brent contract on Friday touched $99.20, the highest price since October 2008.
U.S. crude <CLc1> fell 4 cents to $91.50.
In its latest monthly report on Tuesday, the IEA, which advises 28 industrialised countries on energy policy, said world oil demand growth in 2011 would be slightly higher than it had previously expected, although it would not reach the "exceptional levels" of last year. [
]Its emphasis was still bullish compared with the Organization of the Petroleum Exporting Countries, whose members have consistently said the world has enough oil and any price rises were the result of non-fundamental factors.
"Oil prices have recently been driven by technical matters such as events in Alaska and the North Sea. Also, the weak dollar and speculation have added to this, pushing oil prices higher, especially Brent," Secretary General Abdullah al-Badri said in a statement on OPEC's website.
The tone echoed OPEC's monthly market report on Monday in which it said inventories should rise over the first part of the year. [
]Anticipation OPEC will not take any early action to adjust supplies has given justification to market bulls who have been pushing the market towards $100, especially for Brent, the European benchmark, which has faced tighter supplies than the U.S. marker.
LOSING STEAM?
Some traders said a rally that set in the last part of 2010 was losing steam.
"It's been going up for two months solidly. $100 is some sort of psychological challenge," said Christopher Bellew of Bache Commodities brokerage, adding "a retracement" was more likely in the near term.
A Reuters technical report showed U.S. crude could fall to $89.51.
U.S. crude has been trading below Brent since August last year, reflecting high levels of inventory at Cushing, Oklahoma, the delivery point for U.S. futures. U.S. supplies should increase following the restoration of flows through Alaska's crude oil pipeline on Monday. [
]Many traders have agreed with OPEC that factors beyond supply and demand fundamentals have played a major part in oil's rally as prices have followed strengthening equity markets and a weakening U.S. dollar, which can stimulate buying of dollar-denominated commodities.
The euro <EUR=> extended gains against the dollar on Tuesday in response to a stronger than expected survey on German economic sentiment. [
