China’s Producer Price Index climbed 3.9% year-on-year in May 2026, marking the sharpest rise in factory-gate prices since July 2022. The acceleration from April’s 2.8% gain signals that the world’s second-largest economy has decisively left behind a deflationary stretch that lasted over three years.
For context, Chinese producer prices were stuck in contraction territory for 41 consecutive months before finally flipping positive in March 2026 at just 0.5%. Going from barely above zero to nearly 4% in the span of three months is the economic equivalent of going from a crawl to a sprint.
What’s driving the surge
The usual suspects are doing the heavy lifting here: commodities and energy. Geopolitical tensions in the Middle East, particularly the ongoing conflict in Iran, have disrupted supply chains and pushed global commodity prices sharply higher. Those pressures are showing up clearly in China’s production data.
Production materials costs, the broad category covering inputs that factories actually buy, accelerated to 5.2% year-on-year in May. Mining costs exploded by 15.8% year-on-year. Raw materials weren’t far behind at 9.2%. Processing costs, further down the value chain, rose a more modest 2.3%.
