“Wheat futures tumbled on Wednesday morning statements from Russia saying it has agreed to return to the Turkey and UN-brokered grain deal to allow for the continued export of Ukrainian grain through a Black Sea ‘safety corridor’.

Moscow said it has returned to the deal after receiving assurances that Ukraine will not use the maritime safety corridor for military purposes. Russia’s Defense Ministry confirmed it has received ‘sufficient’ guarantees from the Ukrainian government that it will demilitarize the humanitarian corridor, following last week Russia saying its ships had come under drone attack.”
