Russia's exit from the Black Sea Grain Initiative and strikes on Odesa threatened Ukrainian corn exports (a major global supplier), tightening expected trade flows and lifting corn prices within the 5-day window.
Russia's exit from the Black Sea Grain Initiative and subsequent strikes on Ukrainian ports, including Danube export facilities around July 24, threatened Ukrainian corn export flows and drove a trade-flow and risk-premium rally in corn, though the 7-day lag suggests the escalating attacks and US weather were likely co-drivers.

The Black Sea Grain Initiative exit and the Danube/Odesa strikes built a geopolitical risk premium that peaked around July 25.
