China’s May inflation data, released on June 10, offers a surprising narrative. While the Consumer Price Index (CPI) held steady at 1.2% year-over-year, the Producer Price Index (PPI) surged to 3.9%, beating market expectations of 3.5%. This persistent inflationary pressure is not the result of a broad-based macroeconomic overheating. Instead, it is being driven by two hidden, structural forces: supply clearing in the petrochemical sector and the surging cost of the global artificial intelligence boom.

  • China's May CPI held at 1.2% YoY, while PPI surged to 3.9% (above 3.5% forecast), driven by structural factors not overheating.
  • Two hidden drivers: supply contraction in petrochemicals (added 0.2pp to PPI) and AI-related demand (boosted PPI by 2.2pp YoY).
  • PPI may soon breach 4% due to ongoing supply clearing and AI infrastructure; CPI likely remains elevated through Q2.
