Ukraine has announced that it will be enforcing an export ban on wheat beginning on November 15. The move comes after poor weather impacted Ukraine’s wheat harvests and follows in the wake of the US drought, which decimated that country’s wheat crop and led to sharp increases in international prices. Ukraine’s exports are expected to reach 5.3 million tons in November, a level which the Ukrainian government says will exhaust the country’s exportable surpluses.

Global maize markets are currently experiencing a period of excessive price volatility.

Global soybean prices hit an all-time high on Monday in the wake of continuing hot, dry weather across the US Midwest. In addition to pushing prices higher, the drought and subsequent declining soybean stocks and lower expected exports are also causing a period of excessive price volatility in the commodity.
