On 5 October, the Organization of the Petroleum Exporting Countries (OPEC) + which consists of 23 countries, including Russia—a major producer of oil and gas, decided to cut oil production by 2 million barrels per day (Bpd). The core of OPEC + is OPEC which consists of 13 oil producers, accounting for around 30% of global oil production. Of these, Saudi Arabia is the most important country.
Clearly, the OPEC+ decision to reduce oil production could not have been possible without Saudi's agreement. The US did not want the Saudis to reduce global oil supplies and has been deeply upset with the Kingdom.
The Biden administration had lobbied hard over the past few months with the Saudis to raise oil production to soften the market and push prices down. This would have reduced financial flows to Russia which accrue from its hydrocarbon exports.
