As Russia squeezes Ukraine’s ability to export its huge grain harvests, farmers are counting the cost. Russia last month pulled out of an international agreement that facilitated Ukrainian exports via the Black Sea and has since launched a series of attacks on port facilities in the country. Together, those actions have hindered the exit points for three-quarters of Ukraine’s grain. At the sharp end of these moves are Ukrainian farmers, whose tough lot just got harder. While global grain prices rose sharply when the Black Sea deal collapsed, they fell in Ukraine as the local market was flooded by supplies trapped in the country.
