The Laredo
Corridor.

Laredo is a manufacturing corridor, not a commodity one. The same families of goods, vehicles, machinery, and electronics, dominate both directions because parts and finished products cross and re-cross the border inside one production system. That's why about 85% of the value moves by truck and why Port Laredo sits number one for U.S. trade with Mexico. It also means this corridor rises and falls with North American manufacturing, not any single commodity price.

Watch the import and export lines together: when they move in step the production system is healthy, and when they diverge a supply chain is repricing.
