OPEC, Russia and allies agreed on Saturday to extend record oil production cuts until the end of July, prolonging a deal that has helped crude prices double in the past two months by withdrawing almost 10% of global supplies from the market.

The group, known as OPEC+, also demanded countries such as Nigeria and Iraq, which exceeded production quotas in May and June, compensate with extra cuts in July to September.

OPEC+ had initially agreed in April that it would cut supply by 9.7 million barrels per day (bpd) during May-June to prop up prices that collapsed due to the coronavirus crisis. Those cuts were due to taper to 7.7 million bpd from July to December.

“Demand is returning as big oil-consuming economies emerge from pandemic lockdown. But we are not out of the woods yet and challenges ahead remain,” Saudi Energy Minister Prince Abdulaziz bin Salman told the video conference of OPEC+ ministers.

“Prices can be expected to be strong from Monday, keeping their $40 plus levels,” said Bjornar Tonhaugen from Rystad Energy.

Saudi Arabia, OPEC’s de facto leader, and Russia have to perform a balancing act of pushing up oil prices to meet their budget needs while not driving them much above $50 a barrel to avoid encouraging a resurgence of rival U.S. shale production.

It was not immediately clear whether Saudi Arabia, the United Arab Emirates and Kuwait would extend beyond June their additional, voluntary cuts of 1.18 million bpd, which are not part of the deal.

BULGING INVENTORIES

The April deal was agreed under pressure from U.S. President Donald Trump, who wants to avoid U.S. oil industry bankruptcies.

Trump, who previously threatened to pull U.S. troops out of Saudi Arabia if Riyadh did not act, spoke to the Russian and Saudi leaders before Saturday’s talks, saying he was happy with the price recovery.

While oil prices have partially recovered, they are still well below the costs of most U.S. shale producers. Shutdowns, layoffs and cost cutting continue across the United States.

“I applaud OPEC-plus for reaching an important agreement today which comes at a pivotal time as oil demand continues to recover and economies reopen around the world,” U.S. Energy Secretary Dan Brouillette wrote on Twitter after the extension.

As global lockdowns ease, oil demand is expected to exceed supply sometime in July but OPEC has yet to clear 1 billion barrels of excess oil inventories accumulated since March.
