Overview
- The 16.7‑cent‑per‑liter Tankrabatt expired at midnight and ADAC data showed a midday spike on July 1 with Super E10 up about 18.2 cents to €2.15 per liter and diesel up about 20.4 cents to €2.11 per liter.
- The ADAC and the Monopolkommission say many fuel firms raised prices before the legal end of the rebate, effectively preempting the tax change and pushing pump prices higher in the days before July 1.
- The Monopolkommission estimated that only about 7–11 cents of the roughly 17‑cent rebate reached consumers in the final days, while industry associations (bft, en2x) reject that finding and say members passed on the full discount.
- Germany’s 12:00 pricing rule shaped the timing of visible changes because stations may raise prices only once daily at noon, which meant some firms kept prices high instead of cutting them and then applied a large midday increase.
- The Bundeskartellamt warned the oil sector against unjustified mark‑ups and said it will follow up on indications of abuse, a move that could lead to probes or enforcement and immediate cost pressure for motorists after a cheaper June.
