It comes alongside the EU embargo on Russian crude imports and EU-UK sanctions on the shipping of Russian oil and related services. The cap effectively acts as a waiver on those sanctions, if the price paid is at or below it. But while more details are emerging, key unknowns remain, including the price itself and how Russia will react.
