Germany Fuel Prices: Iran War Impact & Current Costs (March 2026)

Rising Fuel Prices Linked to Iran Conflict

Fuel prices are closely tied to the price of crude oil, which has risen sharply since the beginning of the Iran conflict in late February 2026. The market is particularly sensitive due to the disruption of ship traffic through the Strait of Hormuz, a critical waterway for global oil transport. Nearly 30 percent of the world’s oil shipments and around one-fifth of global demand transit this strait at the Persian Gulf.

However, the Fuels and Energy Business Association does not anticipate supply shortages of gasoline, diesel, heating oil, or jet fuel. “The supply of fuels and energy is secure,” the association stated, noting that Germany sources crude oil from around 30 countries, with major suppliers including Norway, the United States, Libya, Kazakhstan, and Great Britain.

Fuel Prices Closely Linked to Crude Oil Prices

The price of heating oil is also increasing as a result of the conflict. According to data from the heizoel24 platform, it had remained almost consistently below €1 per liter throughout the previous year.

The Federal Cartel Office emphasized that it is closely monitoring price developments. “If there are indications of anti-competitive behavior by the oil companies, we will take consistent action against it,” said the head of the authority, Andreas Mundt. “However, I would also like to make it clear that there are no instruments to prevent geopolitically driven price increases at the push of a button.”

The Iran conflict is impacting gasoline and diesel prices. The market is nervous, say experts – and so are consumers.

Gasoline and diesel prices are sometimes exceeding two euros per liter, even as gas prices are also rising. Tourism is also affected.
