Iran Conflict Drives Fuel Price Volatility and Shortage Warnings in Germany

Fuel prices in Germany have seen a decline since May 1, 2026, due to the introduction of a 17-cent per liter fuel discount aimed at easing financial strain on consumers and businesses amid the ongoing Iran conflict. As of May 31, 2026, the average price for a liter of gasoline (Super) stands at 1.98 euros, while diesel costs 1.88 euros. Despite the discount, these prices remain above pre-conflict levels, where gasoline was 1.83 euros and diesel 1.75 euros per liter. The Federal Cartel Office is closely monitoring developments but notes it lacks tools to counteract geopolitical-driven price increases, according to its head, Andreas Mundt.

The volatility stems from disruptions in the Strait of Hormuz, a critical oil shipping route impacted by the conflict, which has led to rising global oil prices. Diesel prices have consistently exceeded gasoline due to their substantial industrial use and Germany's higher dependency on diesel imports. Furthermore, new regulations restrict fuel price increases at gas stations to once daily at noon; however, violations of this rule have been reported.

Adding to the concerns, various organizations issued warnings on May 30, 2026, about potential fuel shortages in Germany driven by the Iran conflict's effects on supply chains. This underlines the broader risks posed by geopolitical tensions to Germany's energy security and the continuing challenge to stabilize fuel availability and prices.
