This week, US wheat futures markets rallied to briefly touch their highest level since late February this year in what has been a notably volatile period of trade. On Monday, aggressive fund short covering took prices to their daily trading limit of 60 cents up - the equivalent of a 9% price gain. The primary trigger for the gains was the Russian military attacks on Ukrainian grain loading terminals on the River Danube. This river has proven an effective export route for Ukraine wheat and other grains since the Russian invasion in February last year.
