Diesel prices have shattered the CHF 2.00 per litre barrier, a psychological and economic threshold that has not been breached since the height of the 2022 energy crisis. For the average Swiss household, the math is brutal: an additional CHF 1,200 per year in energy expenses. Heating oil has skyrocketed from CHF 100 to CHF 150 per 100 litres, a 50% jump that hits homeowners just as late-season snow blankets the Alps. The impact is not uniform; it is a regressive tax that punishes those with limited budgets the hardest. Vincent Kaufmann, a professor at EPFL, notes that car-sharing and public transport usage are already surging as citizens pivot to survive. If prices remain at these levels for six months, we may witness a permanent shift in Swiss mobility habits as the 'car-free' lifestyle moves from a choice to a necessity.
