Oil held losses near a two-month low on fading prospects for a resolution to the protracted U.S.-China trade spat and signs American crude inventories expanded for a fourth week.

Futures lost 0.3% in New York after dropping 0.2% on Tuesday. Relations have deteriorated between the world’s two largest economies ahead of trade talks this week as U.S. officials discuss restricting capital flows into China, while Beijing hinted at retaliatory measures after Chinese tech firms were blacklisted. The American Petroleum Institute reported stockpiles rose by 4.13 million barrels last week, according to people familiar with the data.

Oil is down more than 20% from its peak in April as the prolonged U.S.-China trade dispute adds to a bleak global economic outlook, denting demand. Crude is likely to fall further if the official Energy Information Administration figures due Wednesday also show a gain in American inventories.

“Oil’s fate is linked 100% to the trade talks now with no progress looking likely,” said Jeffrey Halley, a senior market analyst at Oanda Asia Pacific Pte. “Should this be confirmed by the week’s end, oil is likely to come under heavy selling pressure again with WTI threatening key support at $50 a barrel.”
