Oct. 3—The following are summary notes on selected aspects of the world economic breakdown in production and access to food, fuel, and fertilizer/chemicals as of the beginning of the fourth quarter of 2026. The process goes beyond the economic shockwaves that hit in the first weeks following the U.S.-Israeli attack on Iran.

Food. The production of total grains (all types combined) in the world—a metric for food sufficiency—is down, directly as a consequence of the war. Optimistic estimates report that the 2026/27 crop year will see a drop in the harvest of “only” 2.5 percent from the prior year (mostly rice and wheat), but as the planting/growing/harvest cycles proceed in the Northern and Southern Hemispheres, the losses will mount fast. According to the U.S. Department of Agriculture, this year’s world grain production, projected in the range of 2.95 billion metric tons, is far below the estimated 4 billion tons goal of sufficiency for the world, which has never been reached, even before the current logistics crises hit.
