As acknowledged by the Russian pipeline operator Transneft, the Ukrainian company UkrTransNafta stopped pumping crude oil to Central Europe on August 4 due to the Russian non-payment of transit fees. Although the company had ordered the payment of the fees on July 22, the money was returned six days later, according to Bloomberg. And this is due to problems in banking with Russia, whose banks – the majority – have been excluded from the Swift international notification system. In addition, any transaction that could involve covert financing of the Kremlin has been prohibited. The European regulator must resolve the blockade. The companies hope to be able to solve the problem over the next few days, looking for alternatives to transfer the money.
