Germany Fuel Price Debate: Speed Limits and Price Caps

Fuel prices in Germany have reached historic highs following a surge in crude oil costs driven by the ongoing conflict in Iran. On April 2, 2026, diesel prices hit a record 2.346 euros per liter, while Super E10 petrol reached 2.141 euros per liter, the highest level recorded this year.

Current average prices stand at approximately 2.41 euros for diesel and 2.23 euros for petrol. These figures represent a significant increase from the pre-conflict levels of 1.75 euros for diesel and 1.83 euros for petrol.

Oil Supply Disruptions and Market Volatility

The price spike is primarily attributed to the conflict in Iran, which has threatened the Strait of Hormuz. This maritime route is critical for global energy supplies, carrying between 20% and 30% of the world’s crude oil shipments.

As a result of the supply disruptions, Brent crude oil prices soared from approximately $72 per barrel in late February 2026 to over $120 per barrel. The Federal Cartel Office is currently monitoring fuel prices to prevent unjustified increases by oil companies, which experts suggest may be preemptively pricing in further geopolitical risks.

Government Intervention and Price Controls

To stabilize the market, the German government has released oil reserves and introduced new regulations to curb price volatility. As of April 2026, gas stations are prohibited from increasing pump prices more than once per day, with increases permitted only at 12 p.m.

The government stated that before this regulation, some prices were changing up to 22 times a day. The measure is intended to eliminate the rocket and feather effect, a phenomenon where fuel prices rise rapidly in response to crude oil increases but decline slowly when crude prices drop.

While price reductions can still be made at any time, companies that violate the once-daily increase limit face fines of up to 100,000 euros.

Political Debate Over Mitigation Measures

The fuel crisis has sparked a divide within the German government regarding how to provide relief to consumers. Members of Bündnis 90/Die Grünen and Die Linke have called for the introduction of a general speed limit (Tempolimit) on the autobahn to reduce fuel consumption.

This position is supported by some economic experts. Veronika Grimm, a member of a special panel of economists, suggested on April 3, 2026, that temporary speed limits could serve as a smart signal and effectively lower consumption.

However, Economics Minister Katherina Reiche has rejected both the implementation of a speed limit and the introduction of fuel discounts or tax cuts. Reiche has instead indicated that adjustments to the commuter allowance (Pendlerpauschale) are under discussion.

The Social Democratic Party (SPD) has proposed different alternatives. The party has called for a fuel price cap based on the Belgian model. SPD politician Lars Klingbeil has demanded an investigation into the implementation of a windfall tax on oil companies at the European Union level to address excessive profits during the crisis.

Consumer Response

The disparity in pricing across borders has led to a shift in consumer behavior. German drivers are increasingly traveling to Poland to purchase fuel, attracted by lower prices and the presence of price caps in the neighboring country.
