OPEC+ will accelerate oil output hikes and could bring back to the market as much as 2.2 million barrels per day by November, five OPEC+ sources said as the group’s leader Saudi Arabia seeks to punish some fellow members for producing above quotas.

The group agreed to raise output in June, a sign that Saudi Arabia and its allies appear to be weary of cutting output and may be trying to appease President Trump, who has pushed for lower prices.

Oil prices sank Sunday while U.S. stock futures declined after the S&P 500 notched its longest winning streak in more than 20 years last week.
