Russia’s invasion of Ukraine means the food inflation that’s been plaguing global consumers is now tipping into a full-blown crisis, potentially outstripping even the pandemic’s blow and pushing millions further into hunger.

Together, Russia and Ukraine account for a huge portion of the world’s agricultural supplies, exporting so much wheat, corn, sunflower oil and other foods that it adds up to more than a tenth of all calories traded globally. Now, shipments from both countries have virtually dried up.

Commodity markets are soaring — wheat is up about 50% in two weeks and corn just touched a decade high. The surging costs could end up weighing on currencies in emerging markets, where food represents a bigger share of consumer-price baskets. And analysts are predicting export flows would continue to be disrupted for months even if the war were to end tomorrow.
