China's 2021-22 producer price surge
Coal and commodity prices drove China's producer price index into double-digit year-on-year growth in late 2021. Consumer inflation stayed near 1% throughout, creating the same upstream-downstream split now reappearing.
Beijing intervened in coal markets and capped prices, and producer inflation eased through 2022.
The episode showed that imported and commodity-driven cost shocks can fade without reaching household budgets when demand is weak.
October's 5.7% producer reading and 0.7% consumer reading repeat the 2021-22 pattern of hot factory prices and cold consumer prices.
