(Bloomberg) -- Oil extended gains as tensions in the Persian Gulf remained elevated after Iran seized a British tanker, and Libyan production fell after an unidentified group reportedly shut the country’s largest field.
Futures in New York rose as much as 1.1% after closing up 0.6% on Friday. The U.K. demanded the immediate release of the Stena Impero, which was seized by the Islamic Republic in the Strait of Hormuz on Friday, but Defense Minister Tobias Elwood said in a Sky News Interview that he wanted to de-escalate the situation. Production at Libya’s Sharara oil field was said to be gradually resuming after a force majeure was declared following the closure.
Oil volatility rose to a two-week high on Friday after the tanker seizure highlighted the risk of flows through the world’s most critical crude choke-point being disrupted. Meanwhile, falling production in Libya is now putting the spotlight back on supply threats after prices fell more than 8% in the four days through Thursday on signs of flagging demand in major global economies.

“Crude has been weighed down by concerns that demand is slowing, but the focus is now shifting back to supply and geopolitical risks, which should support prices for the time being,” said Kim Kwangrae, a commodities analyst at Samsung (KS:005930) Futures Inc. in Seoul.
