Benchmark oil prices posted a weekly loss after a choppy day of trading on Friday, pulled down by worries about a global economic slowdown.
OPEC-led supply cuts and U.S. sanctions against Venezuela provided crude with some support.
U.S. West Texas Intermediate crude futures stood ended Friday’s session 8 cents higher at $52.72 per barrel, ending the week down 4.6 percent, their steepest weekly loss this year.
International Brent crude futures had erased earlier losses around 2:30 p.m. ET, gaining 51 cents to $62.14 per barrel. On the week, they are set for a loss of about 1 percent.
Weighing on financial markets were concerns that a trade dispute between the United States and China would remain unresolved, denting global economic prospects.
U.S. President Donald Trump said on Thursday that he did not plan to meet Chinese President Xi Jinping before a March 1 deadline set by the two countries to strike a trade deal.
Adding to demand concerns, the European Commission sharply cut its forecasts for euro zone economic growth due to global trade tensions and an array of domestic challenges.
Another factor weighing on oil prices this week was a strong dollar.
“It seems that macro risk still prevails over constructive supply fundamentals in the oil market,” Harry Tchilinguirian, global head of commodity markets strategy at BNP Paribas, told the Reuters Global Oil forum.
Supply cuts led by the Organization of the Petroleum Exporting Countries lent support. OPEC kingpin Saudi Arabia reduced its output in January by about 400,000 barrels per day to 10.24 million bpd, OPEC sources said.
Another risk to supply comes from Venezuela after the implementation of U.S. sanctions against the OPEC member’s petroleum industry in late January. Analysts expect this move to knock out 300,000-500,000 bpd of exports.
For the time being, though, the sanctions impact on international oil markets has been limited.
“The oil demand side of the coin is facing a number of headwinds … Venezuela’s oil woes are largely priced in and there is no guarantee that the OPEC+ supply pact will be extended,” PVM analysts wrote.
“This is hardly a recipe for a sustained bout of upward buying pressures. There is, however, one potential lifeline for those of a bullish disposition. The rumour mill is in full swing that the Trump administration will not renew waivers to sanctions against buying Iranian oil.”
