Climate, conflict, and the price of bread
March 2026 · 11 min read
Wheat is the most political crop on earth. It feeds two billion people directly, anchors the social contract in dozens of import-dependent countries, and trades on a market thin enough that a single Black Sea disruption can move prices twenty percent in a week.
Three forces have made that market structurally more volatile. Climate change has shortened growing seasons in the Northern Hemisphere breadbaskets. Conflict in Ukraine has put a permanent risk premium on roughly fifteen percent of global exports. And export bans — used by India, Russia, and Argentina in recent years — have eroded trust in the global trading system.
The countries that pay the price are not the ones in the headlines. Egypt, Tunisia, Bangladesh, and a long list of sub-Saharan importers spend an outsized share of their foreign-exchange reserves on grain. When prices spike, currencies weaken, and the IMF's phone rings.
Expect 2026 to test the system again: La Niña conditions in Argentina, election-year politics in India, and a fragile Black Sea corridor that one missile strike could close.
