- China's producer price index jumped 3.9% year-on-year in May, the highest since July 2022, beating forecasts of 3.8% and accelerating from April's 2.8%
- The Iran war has throttled Strait of Hormuz traffic, disrupting energy flows and pushing factories' fuel and power purchasing prices up 10% YoY (widening from 4.4% in April)
- Non-ferrous metal material costs surged 22% YoY, with mining up 36.5%, while AI-driven demand for semiconductors, electrical machinery, and computing hardware added further wholesale price pressure, per NBS chief statistician Dong Lijuan
- Consumer CPI rose just 1.2% YoY in May, missing the 1.3% estimate, as weak domestic demand limited pass-through — though gasoline prices for consumers still spiked 23.5% YoY
- China has trimmed its crude oil imports by nearly 20% since the war began and leaned on strategic stockpiles and renewables, cushioning the shock and actively capping global oil prices, per Wind Information customs data
- Analysts warned supply-driven reflation is squeezing factory margins; eToro's Josh Gilbert said companies face rising costs without pricing power, while HSBC's Frederic Neumann noted consumers are 'keeping a tight fist around their hard-earned renminbi'
- Export growth held up at 19.4% YoY in May — the largest jump in three months — supported by soaring demand for renewable and AI-related goods
Why it matters: The widening PPI-CPI gap (3.9% vs 1.2%) shows input costs are racing ahead of pricing power, squeezing Chinese factory margins while weak consumer demand blocks pass-through. Beijing's ~20% crude import cut and strategic stockpiles have shielded consumers but also act as a meaningful cap on global oil prices — a lever most coverage underweights.
