But while the global wheat price index rose by around 23% in the months following Russia’s invasion, prices began to drop in June 2022. By December, they had returned to pre-war levels. Even when acknowledged, this trend was attributed to the success of the Black Sea Grain Initiative (BSGI), a United Nations-backed agreement that lifted the Russian blockade of Ukraine’s grain exports. Conversely, Russia’s recent decision to pull out of the deal has raised concerns about its potential effects on the global grain trade.
These concerns are misguided for two reasons. First, the global wheat supply (both total production and the traded amount) has remained steady since the onset of the Ukraine war. The Agricultural Market Information System, administered by the Food and Agriculture Organization of the United Nations, incorporates data from the International Grains Council to provide estimates of supply, usage, and trade. Between July 2021 and June 2022 – a period when wheat prices peaked – global production rose by five million tons while trade volumes increased by three million tons. Over the same period, stocks rose slightly (by three million tons).
