What Would Germany’s Fuel-Tax Relief Change at the Pump?
Fuel prices in Germany are climbing again. Some stations now charge more than 2.50 euros per liter. The ADAC puts the national daily average for E10 petrol at 2.29 euros, a new high. Diesel sits at 2.41 euros, just a few cents below the record set earlier this year during the Iran war.
The cause is familiar: fresh escalation around the Persian Gulf. Attacks on a Saudi pipeline, Houthi gains near the Red Sea, and the continuing blockade of the Strait of Hormuz have all pushed up the price of crude oil and refined fuel.
Friedrich Merz, the CDU leader, has responded with a promise. He has signaled a tax cut on fuel and said relief could arrive quickly and precisely. He described an existing “tool” that would do it, without giving details. The obvious instrument is Germany’s energy tax on petrol and diesel. A temporary reduction would lower the state’s share of every liter sold, giving stations room to cut prices if competition works as intended.
That “if” matters. Germany already has a rule to slow down price swings. Since April, fuel companies are allowed to raise prices only once per day, at exactly noon. The measure was meant to stop the minute-by-minute jumps that frustrated drivers and to create more planning security. It does not set a maximum price. It only imposes a rhythm.
The SPD has gone further, proposing a cap on fuel prices and a windfall tax on energy companies. According to sources cited by Stern, Germany’s Economics Ministry considers both ideas problematic. Price caps are not unknown in western Europe. Belgium and Luxembourg operate them, using a pre-agreed formula to determine the highest allowable price for petrol and diesel. Germany, however, has no such mechanism in place, and the ministry’s doubts suggest it is not likely to get one soon.
Direct payments to households are another idea that keeps surfacing. Here the practical problem is administrative. A spokesperson for the Finance Ministry says only about 19 percent of taxpayers have their IBAN on file with the authorities. Any attempt to send out targeted rebates would first require collecting the missing bank details from millions of people, which is not a speedy process.
So what is at stake? Fuel prices are the most visible inflation there is. They show up on every corner, and they hit lower-income households hardest because mobility takes up a larger share of their spending. A tax cut would provide relief at the pump immediately, but it also costs the state revenue at a time when energy markets are unstable. If crude and refined product prices keep rising because of supply disruption, the state would be losing money while drivers still face high or even higher prices.
Merz’s signal is, at this point, more of a political position than a finished policy. The available options are clear: cut taxes, cap prices, or send money directly. Each has its own mechanics and its own political price tag. None of them changes the underlying problem, which is the physical supply of fuel through a volatile and dangerous region.
