Brent eases but on course for weekly gain

LONDON (Reuters) - Oil prices edged lower on Friday in quiet trading, though Brent futures were set for a weekly gain thanks to Saudi Arabia halting crude transport through a key shipping lane and easing trade tensions between Washington and Europe.

Brent futures were down 13 cents at $74.41 a barrel by 0954 GMT but on track for a first weekly increase in four.

U.S. West Texas Intermediate futures were 18 cents down at $69.43 and set for a fourth week of declines.

"The major source of bullish impetus stemmed from Saudi Arabia's decision to temporarily halt all oil shipments through the Bab al-Mandeb Strait," brokerage PVM's Stephen Brennock said. "Yet even this only had a limited impact in spurring buying pressures, with no sign of actual supply disruptions."

Any move to block the strait would virtually halt oil shipments through Egypt's Suez Canal and the SUMED crude pipeline linking the Red Sea and Mediterranean.

An estimated 4.8 million barrels per day (bpd) of crude oil and refined products flowed through the Bab al-Mandeb strait in 2016 towards Europe, the United States and Asia, according to the U.S. Energy Information Administration.

A breakthrough in U.S.-EU trade talks also lent support.

U.S. President Donald Trump and Jean-Claude Juncker, president of the European Commission, struck a surprise agreement on Wednesday that alleviated the risk of an immediate trade war.

"If the U.S.-EU trade talks pull a rabbit out of the hat, that could be very positive for risk appetite, and that could certainly help oil," BNP Paribas oil strategist Harry Tchilinguirian told the Reuters Global Oil Forum.

Russian energy minister Alexander Novak on Friday said the market remains volatile and responds to verbal interventions, adding that the market has priced in risks related to U.S. sanctions against Iran.

He said that the Organization of the Petroleum Exporting Countries (OPEC) and its allies are not discussing an option to boost production by more than 1 million bpd.

OPEC and other oil producers led by Russia agreed last month to ease production curbs. The deal effectively increases combined oil output by 1 million bpd, of which Russia's share stands at 200,000 bpd.

"Gasoline, the big performer of the week, has provided crucial underlying support to the market," said Petromatrix strategist Olivier Jakob.
