Insights · Compliance · Russian oil price cap
The price cap is not a tariff and not a ban on the oil itself. It is a ban on the services that move oil — insurance, shipping, finance — with a carve-out that only applies below a set price. That single design choice reshaped the tanker trade and conjured a shadow fleet to dodge it.
When the G7 set out to cut Russia's oil revenue after the 2022 invasion of Ukraine, it faced a dilemma. A blunt embargo on Russian seaborne oil would have pulled millions of barrels a day off the market and sent prices soaring — punishing the very economies imposing the sanction. The answer was an unusual instrument that worked through shipping rather than around it: the price cap.
Introduced by a coalition — the G7 (the US, UK and EU, plus Australia, Canada and Japan) — the cap took effect on 5 December 2022 for seaborne Russian-origin crude oil, and on 5 February 2023 for refined petroleum products. The aim was deliberately twofold: keep Russian oil flowing to avoid a supply shock, while squeezing the price Moscow could realise for it.
The mechanism is the part most people get wrong. The cap does not order anyone to sell oil at a particular price. It is a ban on providing maritime services — insurance and P&I cover, shipowning, chartering, trading, broking, financing — for cargoes of Russian oil, with a single carve-out: those services may be provided if the oil was sold at or below the cap price. Above the cap, the services ban applies in full.
The lever works because of who dominates the maritime economy. So much of the world's shipping capacity, and the overwhelming majority of its marine insurance and trade finance, is Western or routes through Western firms. By conditioning access to that service web on a price, the coalition could in theory keep tankers moving Russian oil while capping the revenue per barrel.
The original crude cap was set at USD 60 per barrel. As of 2026 it no longer sits there. The EU, the UK, Canada and others lowered the crude cap to USD 47.60 per barrel, effective 2 September 2025 — the EU adopting it within its 18th sanctions package, with the UK aligning. The United States did not join the lowering, leaving a split coalition on the headline figure.
| Date | What changed | Cap level |
|---|---|---|
| 5 Dec 2022 | Crude oil cap takes effect (G7/EU/UK + AU/CA/JP) | $60.00 |
| 5 Feb 2023 | Cap extended to refined petroleum products | tiered* |
| 2 Sep 2025 | Crude cap lowered by EU, UK, Canada & others (US did not join) | $47.60 |
| As of 2026 | Crude cap in force under the lowered figure | $47.60 |
*Refined products are capped under separate tiers for premium-to-crude and discount-to-crude grades. All figures date-stamped to 2026; sanctions levels move, so always confirm against current OFSI, OFAC and EU Council guidance.
For a shipowner, insurer or trader, compliance turns on two things. First, price attestations — a record passed along the transaction chain confirming the oil was bought at or below the cap. Each actor relies on the documentation of the one before it, so the paper trail follows the barrel. Second, vessel screening: checking every tanker involved against the growing lists of designated ships maintained by the EU, the UK's OFSI and the US OFAC.
The cap is enforced not by inspecting the oil but by following the services that move it — and by naming the ships that try to slip the net. Russian Oil Price Cap, HM Treasury / OFSI guidance
The durable key for that screening is the IMO number. Because a tanker can be renamed and reflagged to muddy its identity, designations are attached to the hull's permanent seven-digit number, not the name on the bow — exactly the problem covered in our guide to how to check if a ship is sanctioned.
The cap's biggest side-effect was the rapid growth of a shadow fleet — also called the dark or grey fleet. These are typically older tankers, often with opaque ownership, obscure flags of convenience, and non-Western insurance (or no genuine cover at all). Operating entirely outside the Western service web, they can move Russian oil without ever touching the attestation regime or the cap. Our explainer on the shadow fleet goes deeper on how these vessels are structured and tracked.
Authorities have responded by designating individual tankers by name and IMO number, denying them port access, services and reinsurance. That, in turn, makes beneficial ownership the next battleground — because a single listed owner can pull a web of vessels into scope, a dynamic that connects directly to the OFAC 50 percent rule.
For brokers, charterers, insurers and port operators, the cap turned routine due diligence into a compliance front line. A single mis-screened vessel can mean a sanctions breach, a frozen cargo, or reinsurance pulled overnight. The practical defence is the same one the regime itself relies on: identify the ship by its fixed IMO number, then run it against the live designation lists.
That is precisely what the Marifest registry is built to do. You can look up any of 97,000+ vessels by name or IMO number, read the ownership chain and flag history, and see the sanctions verdict across the OFAC, EU, UN and UK lists — all anchored to the one identifier a tanker cannot quietly shed.
How Marifest helps
The price cap is enforced one ship at a time, against lists that grow every month. Marifest keys every vessel file to its IMO number, so a rename or a reflagging never breaks the screening trail across OFAC, EU, UN and UK designations.
Sanctions screening runs on the permanent IMO number, so a tanker that renames or reflags to dodge a listing still ties straight back to its record.
Opaque ownership, obscure flags and missing genuine insurance are exactly the markers that put a tanker outside the cap's service web — and onto the watchlists.
Each vessel is tied to its owner, manager and operator, so a single listed entity pulling a web of ships into scope is visible at a glance.
Matching runs against OFAC, EU, UN and UK designations together, so a cap-related listing on any one of them surfaces in the same vessel file.
