Chicago wheat prices have dropped to their lowest in over a week due to the resumption of maritime grain exports from Ukraine, easing supply concerns. Meanwhile, corn and soybeans prices have risen for the first time in three sessions, although this gain is limited by better-than-expected weekly U.S. crop ratings. The first grain-carrying ship has safely anchored off Turkey's coast, marking the first since the start of the war. Global wheat export business is on the rise, with Algeria and Jordan among the buyers. However, corn and soy futures are facing pressure due to improving U.S. production prospects, as shown by the USDA's improved rating for soybeans and steady conditions for corn.
