1. The Question Everyone Is Asking
Is Mexico’s nearshoring boom just a one-off post-COVID story… or has it become a structural part of the global auto supply chain?
Looking at OEM import data by strategy (IMMEX–USMCA, IMMEX–Non USMCA, Virtual, Other) from 2020–2024, and then the more recent Jan–Oct 2024 vs Jan–Oct 2025 cut, you can actually see both phases:
A build-out phase where the Mexican ecosystem thickens.
A stress-test phase where volume falls, but the “nearshoring core” holds and even deepens.
The key protagonist throughout is the same: virtual operations.
2. 2020–2024: Building the Nearshoring Core
Between 2020 and 2024, Mexican auto OEMs almost doubled their imported inputs (from about $41B to $76B). That’s the classic nearshoring headline. But the more important story is how that growth was routed:
IMMEX–USMCA imports rose strongly and remained about half of total imports, confirming North American regionalization.
IMMEX–Non USMCA imports (largely Asia/Europe) also grew fast and kept roughly a 27–28% share, showing that Mexico acts as a global input hub, not a closed regional bubble.
Virtual operations grew even faster:
Their share of total imports climbed from ~17% in 2020 to over 20% in 2024 (peaking near 23% in 2023).
They contributed more to growth than their initial weight, a classic positive shift–share effect.
In other words, as OEMs ramped up production, they didn’t just import more parts directly. They built out a multi-tier Mexican network, moving more value between IMMEX entities via virtual operations before it reached final assembly.
That’s the build-out: Mexico evolving from a simple assembly location to a layered production ecosystem.
3. 2024–2025: The Stress Test
The more recent data (Jan–Oct 2024 vs Jan–Oct 2025) shows a very different macro backdrop:
Total imports fall ~7.7%
2024 Jan–Oct: $62.4B
2025 Jan–Oct: $57.6B
In a softer cycle, you’d expect across-the-board cuts. But the adjustment is not symmetric by strategy:
IMMEX–USMCA: –9.6%
IMMEX–Non USMCA: –15.9%
Virtual operations: +6.8%
Other combinations: +27.9% (from a tiny base)
As a result, the import mix changes:
Virtual’s share jumps from ~20.2% to ~23.3% (+3.1 p.p.).
Non-USMCA share falls from ~28.2% to ~25.6%.
USMCA also edges down slightly from ~50.6% to ~49.5%.
A simple shift–share decomposition tells the story clearly:
If 2025 had kept the 2024 structure, virtual imports would be around $11.6B.
Actual 2025 virtual imports are ~$13.4B.
That extra ≈$1.8B is not about overall growth (there isn’t any). It’s pure structural reallocation: in a downturn, OEMs are cutting direct imports—especially from Non-USMCA origins—and routing more of what remains through virtual operations inside Mexico.
This is the stress test: when the cycle goes down, the nearshoring core is not unwound, it’s reinforced.
4. The Nearshoring Core Index: From Expansion to Resilience
If you track a simple Nearshoring Core Index (NCI) that gives more weight to virtual operations (their share and contribution to growth), the story is:
2020 → 2023: the NCI jumps sharply as virtual flows grow faster than total imports and gain share.
2024: NCI remains structurally higher than in 2020, even as growth slows.
Jan–Oct 2025: despite a near 8% drop in total imports, the NCI rises again versus 2024, as virtual operations increase their share of the pie.
In short: The boom years built the nearshoring core.
The slowdown proved it’s now embedded in how OEMs actually run their supply chains.
5. Why This Matters for Strategy
For OEMs, suppliers, and investors, the combined 2020–2024 and 2024–2025 story supports three strategic conclusions:
Mexico is not just an assembly site – it’s a multi-tier production system.
The rise of virtual operations is a concrete, operational signal that value is being created and recombined across multiple Mexican plants before vehicles roll out.Nearshoring is evolving from “where we locate plants” to “how we absorb shocks.”
In the 2025 slowdown, OEMs trimmed direct imports (particularly Non-USMCA) but protected and expanded the virtual channel. That’s what a real risk-management architecture looks like.Opportunities are concentrated where the virtual intensity is highest.
Clusters, OEMs, and suppliers with a high and rising share of virtual operations are precisely the places where:Local content requirements can be met more easily,
De-risking from distant suppliers is already in motion, and
Further investment in modules, sub-assemblies, and advanced components can plug straight into an existing, functioning ecosystem.
