Those output cuts, in place since the start of the year, have lent prices some support, but in recent weeks rising output from Libya and Nigeria - OPEC members exempt from the output reduction deal - has pushed supply higher. Libya and Nigeria, two members exempt from the agreement so they can steer oil revenue to national security efforts, added almost a quarter-million barrels per day to the market between May and June.
The market will be closely watching OPEC's data on Wednesday, but it typically gives production numbers, not exports.
Crude futures continued to move higher Wednesday, riding on optimism that US crude inventories likely shrank again last week. US 2018 demand is expected to increase by 360,000 bpd, up from 310,000 bpd previously.
USA crude briefly rallied to a session high of $46.48 a barrel after the data was released before paring gains.
Domestic crude oil production rose by 59,000 barrels week over week and is now 912,000 barrels a day higher than at the same time past year.
Brent crude LCOc1, the global benchmark, grew 73 cents to touch at $48.25 a barrel, while United States crude CLc1 increased by 81 cents to $45.85, reported Reuters.
Saudi Arabia, the group's largest producer, which implemented the biggest cut, told OPEC it pumped 10.07 MMbpd last month, exceeding its cap for the first time.
That has been a pattern for several months, with many traders still skeptical of a changing market because US production is rising and stockpiles aren't falling as quickly as some expected.
After the close and the supportive API data, Benchmark Brent LCOc1 futures rose $1.25, or 2.7 percent, to $48.12 a barrel. "The price of crude oil, which accounts for about half the retail price of gasoline, has declined in recent months on rising USA crude oil production and high petroleum inventories". If confirmed by the Energy Information Administration later in the global day, it would show strong USA gasoline demand thanks to the annual summer driving season.
The price crash follows a monthly report from the Organisation of the Petroleum Exporting Countries (Opec), which showed production among its members increased in June. "US ethanol production is on track to reach a record high this year of just over 1 million barrels per day, and then decline slightly in 2018". As per an article published on Bloomberg, Russia will likely disapprove any talks related to deepen the crude oil output cuts in the meeting slated on July 24 beyond the current limit effected by OPEC and some other oil producers.
Electricity: "Forecast milder temperatures for this summer compared with last summer will reduce the need for air conditioning, resulting in the average US household consuming 5% less electricity from June through August".
