OPEC oil output has risen by about 1 million bbl/d in August, a Reuters survey found, as the group and allies eased record oil supply curbs as the global economy and demand began to recover from the coronavirus pandemic.

The 13-member OPEC pumped 24.27 million bbl/d on average in August, the survey found, up 950,000 bbl/d from July's figure and a further boost from the three-decade low reached in June.

An easing of lockdowns and lower supply from OPEC, Russia and allies, known as OPEC+, have helped oil climb above $46/bbl from April's 21-year low of below $16. Still, concern of a coronavirus second wave is weighing on price gains and focusing minds in OPEC.

"Now we are on better ground, but a full recovery is not there yet," said an OPEC delegate. "We must continue to monitor the market and coronavirus situation very carefully."

OPEC+ from May 1 made a record cut of 9.7 million bbl/d, or 10% of global output, after the virus destroyed a third of world demand. From Aug. 1, the cut tapered to 7.7 million bbl/d until December, of which OPEC's share is 4.868 million bbl/d.

In August, OPEC countries bound by the deal delivered 99% of the pledged reduction, the survey found. Compliance in July was revised up to 95%.

Saudi, UAE

August's increase is similar to that seen in July and means OPEC is now pumping almost 2 million bbl/d more than June's figure, which was the lowest since 1991 based on Reuters surveys and OPEC data.

The biggest rise in supply in August came from Saudi Arabia, which pumped 9 million bbl/d, up 600,000 bbl/d from July and close to its new quota, the survey found.

The second-biggest rise came from the United Arab Emirates (UAE), which pumped more than its quota after hot weather and people holidaying at home boosted local demand. Kuwait also raised output, remaining in line with its new target.

Smaller increases came from Angola and Algeria.

Iraq and Nigeria, laggards in previous months of the OPEC+ deal, both reduced output, the survey found, with Iraq reaching its highest compliance in recent years.

The cut from Iraq, though, was less than the volume pledged and Nigeria, while boosting compliance significantly, remains short of the 100% level according to the survey.

Iranian, Venezuelan and Libyan supply was little changed. All three are exempt from voluntary cuts because of U.S. sanctions or internal issues limiting output. Libyan output may begin to rise if proposals to lift a months-long oil blockade are adopted.

The Reuters survey aims to track supply to the market and is based on shipping data provided by external sources, Refinitiv Eikon flows data, information from tanker-trackers such as Petro-Logistics and Kpler, and information provided by sources at oil companies, OPEC and consultants.
