- Lucas: So Mexico just crossed a threshold that would have been unthinkable five years ago. In the first quarter of 2026, Mexico became the single largest source of cars imported into the United States, accounting for nearly 38 percent of all auto imports. That is up from about 32 percent in 2020, and it officially edges out Japan and Germany combined. Luna: And China? I remember when people were panicking about Chinese auto imports flooding the US market. Lucas: China's share of US auto imports has collapsed to roughly 8 percent. And that's not just tariffs — although the Section 301 tariffs on Chinese EVs certainly didn't help. But the bigger structural shift is that a lot of global auto manufacturers are effectively treating Mexico as their new China. Not just for the US market, but for Latin America too. Luna: So this is the nearshoring story we've been hearing for years, but now it's showing up in hard trade numbers. I'm curious — what's the actual FDI picture? Lucas: Big numbers. Since 2024, Mexico has attracted over 15 billion dollars in foreign direct investment specifically in automotive and auto parts manufacturing. That's more than what went into China's auto sector in the same period, which is a first. Tesla, BMW, Kia, Stellantis — they've all either expanded existing plants or announced new ones in northern Mexico, especially in Nuevo Leon and Sonora. Luna: And the peso has been relatively competitive, right? Even though it's been under pressure from the strong dollar. Lucas: Exactly. The trade-weighted dollar index hit 120.4 as of last week, and while that usually crushes emerging market currencies, the peso has held up comparably well. It's trading around 18.5 to the dollar, which is actually weaker than 2023 but still historically strong. That makes Mexican labor costs very competitive on a global basis. You're looking at wages that are roughly a fifth of US levels for production workers, but with productivity that's closing the gap fast. Luna: But there's a tension here. The strong dollar also makes Mexican exports more expensive in dollar terms eventually, doesn't it? Or does the dollar strength against other currencies more than offset that? Lucas: That's the nuance. The dollar has strengthened against the yen by about 10 percent over the past year — the yen is at 161.4 per dollar as of this week. So Japanese cars actually got cheaper in dollar terms, yet Mexico still gained share. That tells you this isn't just a price story. It's about supply chain resilience, proximity, and the USMCA rules of origin that basically force automakers to source more from North America if they want tariff-free access. Luna: Right, the USMCA requires 75 percent regional value content for autos to qualify for zero tariffs. That's a huge incentive to move production closer. Lucas: Exactly. And that's been the quiet driver of this whole shift. If you're an Asian automaker, you can either build in Mexico and comply with USMCA, or build in China and pay 27.5 percent tariffs on EVs. The math is pretty clear. Luna: But there are real risks. Water scarcity in Monterrey has been a recurring issue. And infrastructure — ports, highways, the electricity grid — all of that is under strain. Lucas: Those are the bottlenecks that could limit the next phase. The Mexican government has been investing, but it's not keeping pace with demand. Some analysts estimate that the auto sector alone will need an additional 2,000 megawatts of power by 2028, and the grid is already struggling in states like Nuevo Leon. Water is an even longer-term question. Monterrey had severe drought restrictions in 2022 and 2024. Luna: So you've got this incredible tailwind from trade policy and cost arbitrage — but the headwinds are infrastructure and resource constraints. Classic emerging market tension. Lucas: Exactly. And speaking of tensions — one thing we haven't mentioned is the political risk. The US presidential election is coming up in November, and both candidates have talked about renegotiating the USMCA or pulling out of it entirely. That uncertainty alone could slow some investment decisions. Luna: But even if the USMCA were renegotiated, the logic of proximity isn't going away. If anything, reshoring back to the US would be even more expensive than nearshoring in Mexico. Lucas: Yeah, I think that's right. The genie is out of the bottle. The auto supply chains that were built over 20 years in China have already started migrating. And once you've invested in a plant in Saltillo or Hermosillo, you're not going to uproot it for a tariff change. You might shift some production, but the core is there. Luna: What about the broader economy? Mexico's current account deficit has been widening, right? Lucas: Yes. The current account deficit was about negative 227 billion dollars in the first quarter, which is up from negative 221 billion a year ago. But that's actually a sign of investment — you import capital goods, machinery, components to build out this manufacturing base. So it's not necessarily a red flag. Exports of goods and services have also been rising, hitting 3.5 trillion annualized. So the trade gap is being driven by investment, not by consumption. Luna: That's a healthier kind of deficit. But with the dollar this strong, and the Fed holding rates steady, is there a risk that the peso weakens sharply and that hurts these import-dependent industries? Lucas: It's a risk. But the auto sector actually imports a lot of components and re-exports finished vehicles, so a weaker peso would make those imported parts more expensive. It's not a simple boost. The real vulnerability is if the peso weakens because of some external shock — a financial crisis or a geopolitical event — that disrupts confidence. But for now, the central bank has kept rates high enough to maintain some stability. Luna: You know, these conversations have been really useful for making sense of what's actually happening in global trade. We try to keep the show ad-free so it stays focused on the substance, and the way we do that is listener support. If today moved your understanding forward even a little, you can find us at buy me a coffee dot com slash fexingo. Lucas: Yeah, it genuinely helps us keep going. No pressure, but if this sort of analysis is valuable to you, that's the best way to make sure it stays free for everyone. And now back to the shift — I want to talk about one specific plant that I think really captures this moment. Luna: Which one? Lucas: Tesla's new factory near Monterrey that started production in late 2025. They're building the next-generation compact platform there, and the plan is to export 60 percent of the output to the US and Canada. But here's the interesting part — Tesla is using a lot of Chinese-made battery components, which could eventually trigger USMCA scrutiny. The USMCA's rules of origin for EVs are stricter than for conventional cars. Luna: So you have this ironic situation where Tesla, the quintessential American EV company, may have to rely on Chinese supply chains in Mexico to hit its cost targets. Lucas: Exactly. And that's the next frontier of trade disputes. The US government is already looking at whether to tighten the rules so that batteries sourced from China through Mexico don't qualify for US tax credits. If that happens, it could force Tesla and others to either build battery plants in Mexico or use us made cells, which are more expensive. Luna: So Mexico is the battleground for the next phase of us china trade competition? Lucas: I think that's exactly right. For decades, Mexico was seen as a low-wage manufacturing base for simple goods. Now it's becoming the hub for advanced manufacturing, EVs, batteries, and semiconductors. The stakes are enormous for both the US and China. And for Mexico, it's a chance to climb the value chain — but only if it can solve those infrastructure and water problems. Luna: What's one number you're watching closely over the next six months? Lucas: The share of auto parts imported by the US from Mexico versus China. Right now, Mexico supplies about 42 percent of US auto parts imports. If that number ticks above 45 percent in the next year, it will confirm that the supply chain shift is permanent. If it stalls, we'll know the bottlenecks are biting. Luna: And the other number? Lucas: Water levels in the Cerro Prieto dam near Monterrey. That's become a proxy for the infrastructure constraint. If we have another drought year, factory expansion plans could get put on hold. Luna: It's a reminder that trade policy alone doesn't build an industry. You need the water, the power, the roads, and the political stability to go with it. Lucas: Exactly. Mexico has the opportunity, but the window won't stay open forever. If it can't deliver on the basics, some of that investment could flow to India or Southeast Asia. But for now, the momentum is very much in Mexico's favor.
