Mexico's nearshoring story spent 2023-2024 being told in terms of headline OEM announcements. The second wave — tier-two component supplier investment — is now landing at scale in the Bajio corridor. Automotive wire harness, injection molding, precision machining, and specialty electronics suppliers are all committing capital, and the industrial vacancy rate across Guanajuato, Aguascalientes and Querétaro has hit historic lows. The second-order investment is where the durable value capture happens.
Key takeaways
- Tier-two supplier investment is now the dominant flow.
- The Bajio corridor is the primary landing zone.
- Industrial vacancy has hit historic lows.
- Wire harness and injection molding lead the mix.
Why the tier-two wave matters more
OEM assembly plants are visible and political — but tier-two supplier buildout is where the wage bill compounds and the domestic value-add rises.
- Wire harness: dominant investment category
- Injection molding: secondary
- Precision machining: growing
- Specialty electronics: emerging
What this does to the industrial real estate cycle
Bajio industrial rents are at historic highs, and the supply pipeline is committed for the next twenty-four months.
What the labor market is showing
Manufacturing wage growth in the Bajio is outpacing the national average by a wide margin.
What could break the trade
A US tariff structure change that redirects supplier decisions back to Southeast Asia.
