Oil was down on Friday, giving up its gains from the previous session over uncertainty as to whether OPEC will commit to extending future production cuts after the current cuts expire at the end of June.
Brent oil futures was down 0.50% to $39.76 by 9:53 PM ET (2:53 AM GMT) and WTI futures slid 0.80% to $37.11, with investors retreating from the black liquid.
But both benchmarks ended the week with a sixth weekly gain over increased optimism over the global economic recovery from COVID-19.
Investors were left disappointed when OPEC+ failed to push up its policy meeting to Thursday, as was widely expected.
The organization is struggling over accusations that some of its members failed to stick to the production cuts agreed to in April. But Russia and Saudi Arabia, two of the biggest global oil producers, are leading the movement to extend the cuts, and OPEC could still hold a ministerial video conference on Saturday or Sunday should adherence to the cuts improve.
