China stabilized grain prices by trading against the market instead of fixing it by decree
the problem
Grain prices swung wildly between glut and famine
background
China's grain markets swung between two extremes every few years: bumper harvests crashed prices so low that farmers couldn't cover their costs, while lean years drove prices so high that ordinary people couldn't afford to eat. Officials had already tried fixing prices by decree, but a legally mandated price that ignored actual supply and demand was either unenforceable, ignored by merchants who traded around it, or actively made shortages worse by removing any incentive to bring more grain to market when it was needed most.
Simply stockpiling grain for emergency famine relief, the traditional response, didn't address the underlying price volatility hurting farmers in good years just as much as it hurt consumers in bad ones. What was needed was a mechanism that could dampen the price swing itself, in both directions, without any legal price ever being declared.
the move
During the reign of Emperor Xuan of Han (r. 74–49 BCE), the official Geng Shouchang extended an existing price-stabilization approach into a formal 'ever-normal granary' (changpingcang) system: the state itself became a standing buyer of grain at harvest, purchasing large quantities — an initial purchase on the order of 400,000 hu is recorded — to support prices when supply was abundant, then a standing seller from its own stockpiles during lean months to hold prices down, trading on both sides of the market rather than declaring any price by decree.
the payoff
The system spread and was refined across subsequent dynasties, reaching its largest scale under the Qing, when a nationwide network of ever-normal granaries held on the order of 2.2 to 3.3 million tonnes of grain and is credited with saving over 100 million lives through famine relief drawn from the same stockpiles used for routine price stabilization.
what came after
The ever-normal granary is cited in economic history as one of the earliest large-scale implementations of a government buffer-stock mechanism for price stabilization — buying low and selling high from a standing reserve rather than fixing prices by decree — a model later echoed in 20th-century commodity buffer-stock schemes and famine-relief systems worldwide.
