In May 2025, Switzerland experienced a 0.7% year-over-year decline in producer and import prices, further deepening from the 0.5% decrease recorded the previous month. This represented the 25th consecutive period of decline and the most significant drop since December 2024, largely due to a more rapid reduction in import costs, which fell by 2.9% compared to 1.8% in April. Conversely, producer prices saw a modest rise of 0.4%, rebounding from a stagnant performance in the prior month. On a month-to-month basis, producer and import prices decreased by 0.5% in May, diverging from expectations and reversing the earlier 0.1% uptick seen in the previous period. This reduction was primarily influenced by declining petroleum prices, with decreases also observed in the costs of electricity, basic metals, and natural gas.
