China's commodity prices spike across chemicals and fuel, fall sharply in metals — mid-March snapshot

In the two weeks ending mid-March 2026, Chinese wholesale prices for industrial materials moved in opposite directions: chemicals and fuel costs jumped 5–19 percent, while copper, aluminum, and zinc dropped 3–5 percent. This tells you what Chinese factories are paying right now for the raw materials they need to keep running, and signals which parts of the economy are heating up and which are cooling.

China publishes these commodity price snapshots to signal real-time pressure in its industrial base. When sulfuric acid jumps 17 percent and methanol 15 percent in two weeks, it means chemical-dependent industries are either scrambling for supplies or that prices are being bid up by competing demand. Copper and aluminum falling hard at the same time suggests demand from construction and electronics is softer than chemical-driven activity. This divergence — chemicals up, metals down — is an early tell for which sectors Chinese policymakers think need watching.
