Fuel prices in Germany have seen a notable rise just before the scheduled termination of the government's temporary tax reduction on petrol and diesel. Despite the tax relief still being in place, motorists have been facing significant increases at the pump, with variations between different fuel stations reaching unusually high levels.

Significant Price Hikes Observed

Recent data indicates that the cost of diesel increased by an average of 24 cents per liter, while E10 petrol rose by about 20.3 cents at midday, according to figures from the ADAC. These increases approach previous record jumps in fuel prices. By early afternoon, the price difference compared to the previous day continued to widen, with E10 up by 5.4 cents and diesel up by 6.7 cents. This marks the sixth consecutive day of rising prices for both fuel types.

On Monday, the national daily average for Super E10 reached 1.86 euros per liter, up 1.6 cents from Sunday. Diesel averaged 1.784 euros per liter, an increase of 1.9 cents. Since the previous Tuesday, E10 has become 4.4 cents more expensive, and diesel has climbed by 5.3 cents per liter. Notably, these increases occurred even though crude oil prices declined during the same period.

Wide Discrepancies Between Stations

There have been significant differences in fuel prices at various stations. While some stations demonstrated typical price patterns, others registered much sharper spikes. The tax discount, implemented in early May, reduced taxes by 16.7 cents per liter for petrol and diesel. However, fuel stations are not legally required to pass the full savings on to consumers, contributing to price disparities.

Queues as Drivers Seek Lower Prices

With the midday price surge anticipated due to the so-called '12 o'clock rule', many motorists took advantage of lower prices earlier in the day. Reports indicated queues forming at some stations as drivers rushed to fill up before the expected increase. Historically, fuel prices have tended to drop again by late morning, leading to speculation that the last opportunity for cheaper fuel would be late Wednesday morning, just before the tax discount ends. However, slower price declines compared to previous days suggest that some of the anticipated increase might be reflected by a lack of the usual midday price drop.

Regulatory Warnings and Ongoing Debate

The Federal Cartel Office has cautioned oil companies against imposing unjustified price hikes. The agency emphasized that businesses should not exploit the transition period to implement price increases that cannot be objectively justified, pledging to investigate any such reports thoroughly.

Investigations have also found that the tax discount was not fully passed on to consumers. While the fuel tax reduction was generally reflected in lower prices, the Cartel Office, along with the ifo Institute and the Monopoly Commission, found that the full benefit was not always realized at the pump--especially for diesel. The precise extent of the pass-through is still under review, but preliminary analysis suggests a notable gap.

Industry Response

Industry associations have disputed criticism regarding incomplete pass-through of the discount. The German association for fuels and energy stated that its members reduced prices by 17 cents per liter when the tax cut was introduced and expects a corresponding increase when the tax returns to its previous level on July 1. Nonetheless, independent studies continue to highlight a shortfall, sparking ongoing debate among regulators, economists, and industry representatives.

• Fuel prices are surging ahead of the end to the government's tax reduction.
• Price differences between stations are larger than usual.
• Authorities are monitoring for unjustified price hikes.
• Debate continues on whether the tax discount was fully passed on to consumers.
