Wheat dropped following the renewal of an agreement that allows Ukraine to safely export grains out of key Black Sea ports, although the duration of the latest extension was disputed.

Ukraine's Infrastructure Minister Oleksandr Kubrakov said over the weekend that the pact had been prolonged for another 120 days, but Russia and an unnamed Turkish official said the extension was only for 60 days. The top two commodities shipped under the deal are wheat and corn, which also fell.
