A new regulation governing fuel price increases in Germany, implemented roughly two months ago, is reportedly causing unprecedented price fluctuations. The rule, intended to provide drivers with more predictable pricing by limiting price hikes to once daily at noon, is having the opposite effect, according to the ADAC, Germany’s largest automobile club. Instead of stability, the ADAC reports record swings in gasoline prices. The regulation allows for unlimited price *decreases* throughout the day, creating a dynamic where prices can fall repeatedly after a noon increase. This disparity is leading to greater volatility than previously observed in the fuel market. The ADAC suggests the rule is not achieving its intended goal of consumer benefit and is instead exacerbating price uncertainty for drivers.
