The Greek competition authority unanimously adopted Decision 896/2025 on 10 December 2025, following a regulatory intervention launched in November 2022 to assess competition across refining, fuel trading and retail sales in Greece. The review covered 95-octane unleaded petrol, diesel and heating oil. The authority concluded that effective competition conditions were absent in the sector.

The decision has binding regulatory effect insofar as it requires companies in the sector to amend fuel storage and service contracts at third-party-owned facilities so that they no longer contain exclusivity clauses concerning fuel storage. The authority’s other measures are recommendations issued under its advisory powers.

To support imports, the authority recommended establishing an independent central body to hold emergency fuel stocks on behalf of obligated companies, under the supervision of the Regulatory Authority for Energy, Waste and Water. The body would charge a set fee allocated among obligated companies according to their previous year’s total consumption, rather than according to their imports. It also recommended creating a unified register to record and monitor petroleum storage facilities, including shortages or unused capacity, and designating an entity to maintain it.

To reduce price transparency at the refining level and the risk of tacit coordination, the authority recommended changing the rules for communicating refinery selling prices to fuel-trading companies. Instead of publishing the prices online, refiners would communicate them individually to each trading company.

To improve retail price transparency for consumers, the authority recommended that the responsible ministry develop a user-friendly digital application showing petrol-station prices in real time by product, station and location. The application would identify nearby stations and their prices based on the user’s location, complementing existing fuel-price databases and the Price Observatory.

The authority’s earlier reports, published in August 2024 and July 2025, examined market structure and competition across the supply chain, the regulatory framework, price and trade developments, profitability, pricing practices and the asymmetric pass-through of price changes known as “rockets and feathers.”
