Although compliance to the cuts had a slow start, OPEC's JMMC noted in a press release following their meeting in Jeddah, Saudi Arabia, that compliance had hit a record high of 168% in April 2019. Average conformity reached 120% since January 2019.

Russia’s GDP unexpectedly grew just 0.5% in the first quarter, below all 14 estimates in a Bloomberg survey. That compares with a 2.7% increase in the last three months of 2018, which was the highest in more than six years as crude output reached a record 11.45mn barrels a day in December, according to ministry data as Opec+ curbs eased.

NPD - Preliminary production figures for April 2019 show an average daily production of 1 729 000 barrels of oil, NGL and condensate, which is a decrease of 24 000 barrels per day compared to March.

Following its 14th Meeting, which took place on 19 May 2019, in Jeddah, the Kingdom of Saudi Arabia, the Joint Ministerial Monitoring Committee (JMMC) has reaffirmed its commitment to achieving a balanced market and working towards oil market stability on a sustainable basis with solid fundamentals.

"We want to bring inventories down to a more normal levels," Falih said. "We need to stay the course and do that in the weeks and months to come."

Russia sees a range of options that would allow OPEC+ to continue output cooperation until year-end, from easing the limits to ending the extreme throttling-back that has seen some countries exceed original cutback targets.

"Work to increase production to full capacity will continue, and in early June Kashagan should reach production levels of 370,000-400,000 b/d due to the work carried out during the maintenance," it said.

Iran has sent abroad between 250,000 bpd and 500,000 bpd of oil so far in May, according to two industry sources who track the flows. Data from Refinitiv Eikon put crude shipments at about 250,000 bpd and exports of crude and condensate, a light oil, at about 400,000 bpd.

Libya is currently pumping almost 1.3 million b/d, National Oil Corporation Chairman Mustafa Sanalla told reporters. While production and exports have so far been unaffected by the recent escalation in fighting between the self-styled Libyan National Army, forces loyal to the UN-backed government and other militia groups, the violence threatens to destroy oil fields and export infrastructure, he said.

U.S. crude oil production sustained a record-tying 12.1 million barrels per day (mb/d) in April while total petroleum demand was the highest for the month since 2007 at 20.2 million barrels per day.
