To try to shed some light on what’s been going on, I’ll use the example of wheat, probably the world’s most important food crop, of which both Russia and Ukraine are major exporters.
According to the U.S. Department of Agriculture, Ukraine was responsible for 8.2 per cent of total wheat exports in the June 1, 2020 — May 31, 2021 marketing year and 9.5 per cent of estimated total exports in the 2021-2022 marketing year. The war’s effects have only kicked in in the last two months, with Ukraine’s share of exports shrinking to less than 5 per cent of the total. According to Ukrainian government data, the drop has been much steeper: In June, wheat exports shrank by a factor of five year-on-year. In any case, even with its Black Sea ports blocked or occupied, Ukraine has kept up a considerable export stream. Deputy Infrastructure Minister Mustafa Nayyem recently posted on his Telegram channel that since the war began, physical cargo volumes sent from Ukraine to Romania have increased 460 per cent; agricultural cargoes taken by rail to the Romanian port of Constanta account for the bulk of that increase.
