The G7, the European Union and Australia agreed to impose a $60-per-barrel price cap on Russian seaborne crude oil and also set an upper price limit for Russian oil products to deprive Moscow of revenues for its invasion of Ukraine.
The IEA, which provides analysis and input to the G7 on energy, does not see the enhanced enforcement of the price caps affecting the global oil and fuel supply, Birol told Reuters in an interview on the sidelines of the summit.
According to Birol, the price cap reached two main objectives: it did not trigger tightness in the markets as Russian oil continued to flow but at the same time Moscow's revenues were reduced.
But there are some loopholes, some challenges for the better functioning of the oil price cap," Birol said.
"There is no determination of any time frame there, but I think the main issue is because of the reliance of especially European countries on Russian gas almost for decades.
