A new rule to limit fuel price hikes took effect in Germany on Wednesday, limiting petrol station to raising prices no more than once a day in a bid to bring down costs for motorists amid a surge in oil prices caused by the Iran war. Under the new restrictions, petrol stations are only allowed to raise prices once at midday to limit price fluctuations and ensure greater transparency.

Irregularities in how the government developed the updated guidelines raise questions about its conclusions.
