Ukraine and the global food supply

Ukraine is among the largest exporters of wheat, maize, barley and sunflower oil in the world. The important question is not the volume but the destination, because that is what determines who is affected when supply is interrupted.

Who actually buys

Egypt, Indonesia, Bangladesh, Turkey, Tunisia, Morocco, Lebanon and a range of East African buyers, together with the World Food Programme purchasing for humanitarian operations.

These are countries that import a large share of their staple calories and where bread is a substantial part of both the household budget and, in several cases, the state budget through subsidy.

How the effect transmits

Not primarily through the absolute availability of grain — the world has other suppliers — but through price and freight. A disruption raises the world price, and the increase falls hardest on the buyers with the least fiscal room to absorb it.

It also raises insurance and freight, which for a distant importer can matter as much as the grain price itself.

Why the corridor mattered beyond Ukraine

Restoring a functioning export route was, for the importing countries, a food price measure. That is a reason the corridor was of interest to governments with no direct stake in the region.

The point worth holding on to

Agricultural trade connects places that have no other connection. A grain terminal on the Black Sea and a bakery in a North African city are part of one system, and the people in the second have no way to influence the first.

Reading this table I think about my own shipping routes: the same Black Sea, the same straits, the same ports. Knowing where the grain leaving here goes explains why the corridor was a matter larger than Ukraine. A country's exports sometimes carry other people's stability more than its own economy.
