Wall Street’s three main stock indexes also fell from last week’s record highs following a report that stoked concerns a U.S.-China trade deal might not get through, which pushed oil prices lower, analysts said. “Crude has become highly reactive to whichever way the wind is blowing in the (U.S.-China) trade talks. When it falters, prices get punished,” said John Kilduff, a partner at Again Capital LLC in New York. “This headwind of slack demand growth keeps holding us back.”

The 16-month trade war between the world’s two biggest economies has slowed global growth, prompting analysts to lower forecasts for oil demand growth and raising concerns that a supply glut could develop in 2020. China and the United States had “constructive talks” on trade in a high-level call on Saturday, state media Xinhua reported on Sunday, but it gave few other details. On Monday, CNBC quoted a Chinese government source saying the mood in Beijing about a trade deal was pessimistic due to U.S. President Donald Trumps reluctance to roll back on tariffs. “The souring trade situation has put a halt to the rally,” said Robert Yawger, director of energy futures at Mizuho in New York, adding crude prices had risen earlier in the session but faded when New York markets opened.

Expectations of lower seasonal demand for gasoline in the United States also weighed on oil prices, said Andy Lipow, president of Lipow Oil Associates in Houston. Concerns about plentiful crude supplies in 2020 weighed on the market, which expects OPEC to extend production cuts in early December to help avoid a new global glut. The Organization of the Petroleum Exporting Countries (OPEC) said last week it expected demand for its oil to fall in 2020, supporting a view that there is a case for the group and other producers like Russia – collectively known as OPEC+ – to maintain limits on production.

OPEC is due to discuss output policy at a meeting on Dec. 5-6 in Vienna. Their existing production deal runs until March.
