The Czech government will reinstate price caps on gasoline and diesel from October 1 and tax refiners on 50% of any margin increase over 2025 levels. The measure targets Poland's Orlen, which operates both Czech refineries, and is expected to raise $260 million a year. The move comes as Saudi Arabia cuts October crude allocations to Europe and the Strait of Hormuz remains closed.

Key Facts

The Czech government will reinstate price caps on gasoline and diesel from October 1, setting maximum daily prices based on a three-day rolling average of four benchmarks plus a regulated margin of 2.50 crowns per liter.
The diesel excise tax drops from 9.95 to 8.011 crowns per liter, the European Union's floor, through October.
The windfall tax would apply to companies processing crude oil with annual revenue above 2 billion crowns, a threshold expected to capture only Poland's Orlen, and would raise an estimated $260 million a year through 2027.
Refining margins at Orlen and MOL reached $50 to $55 a barrel in September, up from a historical range of $15 to $20, according to UBS data cited by economist Lukáš Kovanda.
Saudi Aramco told European term-contract buyers they would receive no October allocations, redirecting roughly 1 million to 1.5 million barrels a day of Gulf exports to buyers in China, South Korea, India and Japan.

Price Cap Mechanics

The price cap sets maximum gasoline and diesel prices daily, calculated as a three-day rolling average of four benchmarks: Orlen Unipetrol, MOL, ČEPRO and Platts quotations, plus a regulated margin of 2.50 crowns per liter ($0.12). The diesel excise tax drops from 9.95 to 8.011 crowns per liter, the European Union's floor, through October. Finance Minister Alena Schillerová put the cost to the state budget at 1.1 billion crowns (roughly $51.9 million) for the month. Schillerová said the measure should "help finance the costs that the crisis brought to consumers and public budgets".

Windfall Tax on Refiners

The windfall tax still needs parliamentary approval, but would apply to companies processing crude oil with annual revenue above 2 billion crowns, a threshold expected to capture one company in reality: Poland's Orlen, which operates both Czech refineries. The levy would apply through 2027 and would raise an estimated $260 million a year. Poland itself taxed Orlen's domestic refining margins several weeks before the Czech measure was announced. Germany, Spain, Portugal, Italy, Poland and Austria have asked the Irish EU presidency to add a windfall tax on refiners to the September Ecofin meeting agenda in Dublin.

Market Pressure and Supply Disruptions

Refining margins at Orlen and MOL, which supply the Czech market, reached $50 to $55 a barrel in September, up from a historical range of $15 to $20, according to UBS data cited by economist Lukáš Kovanda. Houthi forces seized the Yemeni port of Mokha and Perim Island in the Bab-el-Mandeb strait in recent weeks, closing off the Red Sea route Saudi Arabia had used to bypass Hormuz after its East-West pipeline was damaged in a September 11 drone attack. Saudi Aramco told European term-contract buyers they would receive no October allocations, redirecting roughly 1 million to 1.5 million barrels a day of Gulf exports to buyers in China, South Korea, India and Japan instead. Czech gasoline hit 44.22 crowns a liter and diesel 47.79 crowns nationally on September 9, the highest gasoline price since August 2022, and the highest diesel price since April 2026.
