German Finance Minister Lars Klingbeil has called for state intervention to tackle high energy prices, driven by the Iran war. His proposals include a windfall tax, lower energy taxes and a cap on fuel prices. However, these proposals are opposed by Economy Minister Katherina Reiche and Chancellor Friedrich Merz, both members of the conservative Christian Democrats. The government introduced a measure limiting petrol stations to raise prices just once a day, but it has failed to reduce costs. Monika Schnitzer, head of a council of economic experts advising the German government, also criticised state intervention in fuel prices, suggesting people should reduce consumption.
