The UN, Turkey and Ukraine said they would keep the Black Sea grain deal running after Russia's pullout. Over 9.5 million tonnes of corn, wheat, sunflower products, barley, rapeseed and soy have been exported since July under the arrangement, which uses a Joint Coordination Centre to clear ship movements and inspections.
Continued shipments limit the immediate supply shock, but the uncertainty over the corridor's future keeps a risk premium in wheat and corn prices.
After 361 past bullish geopolitics events, Wheat (SRW) moved a median +0.7% over 5 sessions (58% higher; middle half -1.4% to +3.7%), and +1.3% over 20.
After 323 past bullish geopolitics events, Corn moved a median +0.5% over 5 sessions (57% higher; middle half -1.5% to +2.9%), and +0.9% over 20.
