Capital Sands Oil prices trickled a fraction lower on Tuesday but remained near a three-month high as investors kept the faith with hopes that a fully fledged U.S.-China trade deal is in the pipeline and set to stoke oil demand in the world’s biggest economies. Brent crude oil futures had slipped by three cents to $65.31 a barrel, while West Texas Intermediate crude was down 4 cents to $60.17 a barrel. Under a partial trade agreement announced last week, Washington will reduce some tariffs on Chinese imports in exchange for Chinese purchases of agricultural, manufactured and energy products increasing by about $200 billion over the next two years. “While the partial trade deal leaves most of the tariffs in place, it marks a turning point in the dispute which will eventually lead to fully fledged agreement,” analysts from ANZ Bank said in a note on Tuesday. The agreement is yet to be signed and several Chinese officials told Reuters the wording of the agreement remained a delicate issue, with care was needed to ensure expressions used in text did not re-escalate tensions and deepen differences. Lower supply next year due to a planned cut by the Organisation of the Petroleum of Exporting Countries (OPEC) and associated producers like Russia – a grouping known as ‘OPEC+’ – and stronger economic growth expected because of the improved trade outlook between United States and China will combine to tighten the oil supply-demand balance next year, analysts from JP Morgan said. Still, U.S. oil output from seven major shale formations is expected to rise about 29,000 barrels per day in January to a record 9.14 million bpd.
