Greek shippers made almost $4bn on Russian oil

Data showed Greek shipping companies made almost $4 billion transporting Russian oil over the past three years, highlighting how the G7 price cap regime has kept barrels moving while creating large revenue streams for tanker operators. Dynacom Tankers, Stealth Maritime and Onassis Group were among the companies whose revenues rose from carrying Russian fuel.

The figures matter because the price cap was designed to limit Moscow’s oil income without triggering a global supply shock. Shipping firms that can document compliant cargoes, insurance and payment structures remain able to participate in the trade, even as governments tighten scrutiny of sanctions evasion and opaque fleets.

Greek tankers and the G7 cap

The mechanism depends on maritime services: vessels, insurance, finance and documentation. If cargoes are sold below the cap, Western-linked shipping and insurance services can remain available. That has preserved a channel for Russian crude and refined products while giving established tanker owners a legal route to revenue.

For the companies named, the immediate issue is not only income but compliance risk. Any shift in enforcement, documentation standards or price-cap levels could alter which voyages are commercially viable and which counterparties remain acceptable.

For the wider energy market, the trade has helped keep Russian supply

connected to global buyers. If enforcement tightens without replacement logistics, freight costs could rise and Russian barrels may rely more heavily on shadow-fleet capacity.

If the regime holds, mainstream operators can keep earning fees while

the cap remains the central control point.

By July 31, 2026, the key test is whether G7 and European authorities signal tougher enforcement or leave the current compliance framework intact.
