BEIJING: Oil prices edged up on Thursday morning as investors worried about escalating tensions between the U.S. and Iran.

Brent crude ​oil futures were ⁠up 34 cents, or 0.49%, at $69.74 a barrel at 0126 GMT. U.S. ‌West Texas Intermediate crude rose 37 cents, or 0.57%, to $65.00.

Both benchmarks settled higher on Wednesday. Brent futures gained ​0.87% and WTI gained more than 1.05%, as investor worries about U.S.-Iran tensions overshadowed a build ​in U.S. ​crude stocks.

U.S. President Donald Trump said after talks with Israeli Prime Minister Benjamin Netanyahu on Wednesday that they reached no "definitive" agreement on how to move forward ⁠with Iran, but he insisted negotiations with Tehran would continue.

On Tuesday, Trump said he was considering sending a second aircraft carrier to the Middle East if a deal is not reached with Iran, even as Washington and Tehran prepared to resume talks.

U.S. and Iranian ​diplomats held ‌indirect talks last ⁠week in Oman. The ⁠date and venue of the next round of U.S.-Iran talks have yet to be announced.

A sustained ​break above a $65–$66 level would require further escalation in the ‌Middle East, while any de-escalation could quickly trigger profit-taking ⁠back toward $60-$61 in WTI, IG analyst Tony Sycamore said.

U.S. job growth unexpectedly accelerated in January and the unemployment rate fell to 4.3%, the Labor Department said, signaling health in the economy.

"The resilient U.S. economy is also supporting oil demand expectations," said Mingyu Gao, chief researcher for energy and chemicals at China Futures.

A hefty build in U.S. crude inventories capped price gains. U.S. crude inventories rose by 8.5 million barrels to 428.8 million barrels last week, the Energy Information Administration said, far exceeding analysts' expectations in ‌a Reuters poll for a 793,000-barrel rise.

However, since the start ⁠of the year, global oil inventory builds have generally come ​in below expectations and net long positions in overseas crude oil futures and options have not yet reached overweight levels, said Gao.

Oil prices are therefore likely to remain biased to ​the upside, supported ‌by the U.S.-Iran situation, tighter sanctions on Russian oil and expectations ⁠of reduced exports, Gao added.
