SINGAPORE (Bloomberg) - Oil jumped back above $60/bbl after reports of a missile strike on an Iranian tanker near the Saudi Arabian port city of Jeddah reignited fears over military escalation in the world’s most important crude-producing region.

Brent futures surged about $1/bbl after the Islamic Republic News Agency reported a National Iranian Oil Company tanker caught fire after a blast, taking the day’s gains to more than 2%. Two missiles that hit the vessel probably came from the direction of Saudi Arabia, the national tanker company’s head of public relations said in a call with Iran’s Press TV.

The tanker explosion will spur fresh concern about potential conflict in the Middle East after attacks on ships and drones earlier this year and last month’s strike on Saudi Arabian energy infrastructure that briefly cut global supplies by 5%. Prices were already higher Friday on prospects for progress in the U.S.-China trade dispute, offering a glimmer of hope for demand.

“The explosion points to potential geopolitical risks and that has once again surprised the market to the upside,” said Will Sungchil Yun, a commodities analyst at HI Investment & Futures Corp. in Seoul. “It still remains to be seen whether prices will keep rising as investors are putting their focus on the trade talks and the gains won’t last long if the negotiations result in a no-deal.”

Brent crude for December settlement rose as much as $1.36, or 2.3%, to $60.46/bbl on the London-based ICE Futures Europe Exchange. The contract is up 3.2% this week and traded at $60.22/bbl at 8:35 a.m. in London.

West Texas Intermediate for November jumped as much as $1.19, or 2.2%, to $54.74/bbl on the New York Mercantile Exchange. The contract climbed $0.96 to $53.55 on Thursday, the highest level in more than a week. Prices are up 3.1% this week.

The strike ratchets up tension in the Middle East after the attacks on key Saudi Arabian oil-processing facilities Sept. 14 that were blamed on Iran. In July, a U.S. ship down an Iranian drone, while tankers have been targeted in the Persian Gulf.
