U.S. wheat and corn futures have experienced a decline after Russia restored a trade deal that enables agricultural exports from Ukraine. The Black Sea Grain Initiative, which had been suspended due to safety concerns, will now be reinstated, allowing Ukrainian agricultural shipments to resume. However, the United Nations has announced a suspension of these shipments for the next day. In the meantime, wheat and corn futures have seen significant drops, while soybean futures have seen a rise due to concerns about South American weather.
