Oil prices edge up on Iran sanctions, but trade tensions drag

SINGAPORE (Reuters) - Oil prices inched up on Monday as US sanctions against Iran pointed towards a tighter market, although concerns over slowing economic growth amid global trade tensions kept a lid on gains. Front-month Brent crude oil futures LCOc1 were at $72.88 per barrel at 0053 GMT, up by 7 cents from their last close. US West Texas Intermediate (WTI) crude futures CLc1 were up 16 cents at $67.79 per barrel. The United States has started implementing new sanctions against Iran, which from November will also target the country’s petroleum sector. “With US sanctions on Iran back in place  , all eyes have been on the impact on crude oil exports from that country,” ANZ bank said on Monday. “Maintaining global supply might be very challenging,” the bank said, although it added that “the US is doing its bit to increase production, with data showing drilling activity is continuing to rise.” US energy companies last week added the most oil rigs since May, adding 10 rigs to bring the total count to 869, according to the Baker Hughes energy services firm. That was the highest level of drilling activity since March 2015. Also potentially weighing on oil markets are signs of slowing economic growth and fuel demand growth, especially in Asia’s large emerging markets. “Lower demand from China, the world’s biggest importer, comes at a critical time when demand growth from Asia in general is being called into question. This due to the negative impact of trade wars, a stronger dollar and rising funding costs,” Ole Hansen, head of commodity strategy at Denmark’s Saxo Bank, said in a note late last week.
