WASHINGTON: The US on Thursday imposed the first sanctions on owners of tankers carrying Russian oil above the G7 price cap of $60 a barrel, one based in Turkey and one in the United Arab Emirates, in an effort to close loopholes on the mechanism designed to punish Moscow for the war in Ukraine.

The US, other G7 countries and Australia imposed the cap last year, seeking to reduce Russia’s revenues from seaborne oil exports as part of sanctions for its invasion of Ukraine.

The cap bans Western companies from providing maritime services, including insurance, finance and shipping, for Russian seaborne oil exports sold above $60 a barrel, while seeking to keep oil flowing to markets. Caps also were imposed on Russian fuel exports.

US President Joe Biden’s administration placed sanctions on Turkey-based Ice Pearl Navigation SA, owner of the Yasa Golden Bosphorus, which the Treasury said carried Russian ESPO crude priced above $80 a barrel after the cap took effect in December last year.

The US also imposed sanctions on UAE-based Lumber Marine SA, owner of the SCF Primorye, which the Treasury said was carrying Novy Port Russian crude above $75 per barrel.

“Because of the actions we’re announcing today, and the further actions we will take in the coming weeks and months, these costs will continue to rise and Russia’s ability to sustain its barbaric war will continue to weaken,” a senior Treasury official, speaking on condition of anonymity, told reporters in a call.
