What is the Russian oil price cap, and what is the shadow fleet?
The price cap lets Russian oil keep flowing, but only if it is sold at or below a set price when carried by Western ships and insurers. Ships outside that system are called the shadow fleet.
The Russian oil is a rule, agreed by the G7 countries, the EU and Australia, that Western shippers, insurers and financiers may only help carry Russian oil if it is sold at or below a set price: US$60 a barrel for crude oil from December 2022, later lowered by the EU to about US$47.6 from 3 September 2025. The is the name for tankers that carry sanctioned oil outside that Western system. The aim of the cap, as its backers described it, was to keep oil flowing while reducing Russian revenue.
How it was meant to work: finance ministers of the G7 agreed on 2 September 2022 to cap the price of Russian oil and petroleum products, intended to reduce Russia's ability to finance its war on Ukraine while hoping to curb inflation. The cap would be enforced by an that the oil was bought below the set price. The Cap Coalition's companies could provide services such as shipping, insurance and only if the price did not exceed $60.

Russia's government responded. The Kremlin issued a decree prohibiting Russian companies and traders from selling oil to anyone participating in a , later amended to allow sales to friendly countries such as China and India. By May 2023 the G7 countries considered the sanctions successful in achieving oil supply stability and reducing Russian tax revenue, while reports said that by August 2023 the Russian price had risen above the cap and over 50 percent of Russian oil was carried by a outside Western financial and insurance circles.
The International Maritime Organization defines shadow-fleet ships as those engaged in illegal operations to circumvent sanctions, evade safety or environmental rules, or avoid insurance costs. Estimates of how big the Russian fleet is vary; a catalogue kept by the Ukrainian government listed 1,337 ships as of February 2026. The rules also move with events: on 12 March 2026, amid the war with Iran, the US temporarily lifted restrictions on selling Russian oil held on detained tankers, a decision it said was meant to achieve stability in global energy markets, in effect until 11 April 2026.

Recap
The cap works through Western services; a shadow fleet operates outside them.
💡 A trick to remember it · Sell below the cap and Western ships and insurers will carry the oil; sell above it and the oil sails with the shadow fleet.
Surprising fact · In August 2023 the Russian price exceeded the cap, reaching $73.57 a barrel.
