Overview
- The Monopolkommission said on Tuesday that of the roughly 16.7 cents per litre tax cut, about 15–16 cents reached consumers, leaving an estimated €100–200 million of the €1.6 billion cost unpassed to motorists.
- The commission found clear regional variation with the strongest pass‑through in northwest Germany and the weakest in the south, using a conservative comparison of German and French price movements to reach its estimate.
- The Ifo Institute backed the conclusion, especially for diesel, saying some of the subsidy appears to have boosted margins at mineral oil companies while the industry group en2x disputes those findings and says full pass‑through occurred.
- Retail fuel prices have fallen close to pre‑war levels after a US–Iran détente and the tankrabatt, with ADAC data showing diesel around €1.82 and E10 near €1.87 per litre in the recent daily averages.
- The tankrabatt expires on June 30, it cost the treasury about €1.6 billion for May and June, and competition experts and the Monopolkommission are urging Bundeskartellamt probes because ending the measure could quickly push prices higher and hit ordinary drivers.
