What this means

Manufacturing and agricultural economies depend on a small number of global chokepoints. When any of these gets disrupted — Suez closures, Panama drought, Strait of Hormuz tensions — input costs ripple through suppliers within weeks.

What you can do

For procurement teams: track the chokepoint nearest your input lanes — that one is the single biggest risk factor.
Track CME futures for steel and key grains — they move ahead of input-cost changes by ~30 days.
