Oil price cap to strike Russia’s war chest

Leaders of the world’s biggest developed economies are weighing a cap on the price of Russian oil meant to strike at the main pillar of the Kremlin’s finances following its invasion of Ukraine — and to limit the havoc that high energy prices are wreaking worldwide.

Details haven’t been agreed at the Group of Seven summit in Elmau, Germany, but the basic idea would be to tie the price cap to the services that make trading oil possible. For instance, insurers would be barred from dealing with shipments that are above the cap, wherever it winds up being set.
