Mexico has stopped being just a country that exports. It has become a transit point for global money.

When people think of Mexico's foreign trade, they think of a straight line: from Mexico to the United States. And that makes sense. More than 80% of what we export crosses that border. Since 2025, we have been the main supplier of goods to the US economy.

I have spent six years closely watching how money moves through this corridor. And that straight line hides something that almost no one says out loud.

Money does not travel in just one direction. And increasingly less so.

Let's follow the money

On the side of what comes in, the picture is well-known. In 2025, Mexico exported a record of over 660 billion dollars, the vast majority to the United States. Add to that remittances, over 61 billion dollars last year, almost all from the US, and foreign investment, which also mostly arrived from the north.

Up to that point, the story is simple: dollars enter Mexico, and they enter from the north.

On the side of what goes out, the picture has changed.

In 2025, for the first time, Mexico bought more from Asia than from its USMCA partners combined. Asian imports surpassed those from North America. China alone already accounts for nearly 20% of everything we import, and the majority is not finished products: they are components, raw materials, and machinery that enter Mexico, are transformed here, and head out again, often heading back to the United States.

Hold on a second on that.

A large portion of what we sell to the north is manufactured with what we buy from the east.

The multi-currency company that no one decided to be

Let's take this down from the country level to a specific company.

We recently worked with a Mexican manufacturing company that bills millions of dollars a month to clients in the United States. On paper, everything seemed perfect: “we are a dollarized company”.

But upon reviewing their complete operation, something appeared that they were not measuring: a significant part of their raw materials, machinery, and components depended on international suppliers. Although their income was in USD, their costs did not follow the same logic: payments in different currencies, suppliers outside of North America, and purchasing timelines that did not always match their collections.

The owner told us something that summarizes the problem very well:

“We always thought that as long as we sold in dollars, we were covered. Then we realized that the challenge was not just selling more, but ensuring we could buy, produce, and deliver the next order without losing margin.”

The lesson: being an exporter and collecting in dollars does not automatically mean having a protected operation. The margin also lives in how you buy, when you pay, and how prepared your financial structure is.

I have seen this pattern dozens of times. A company exports to the United States and collects in dollars. In their head, it is "a dollar business." But when you review their actual operation, their raw materials come from China, their components from Korea, and their machinery from Germany.

So they collect in one currency, carry costs in pesos, and pay suppliers in yet another.

Three currencies. Three different schedules. Three exchange rates moving at the same time, and not always in their favor.

That is a multi-currency company. Only, no one made the decision to be one. It happened on its own, pushed by how world trade reorganized itself.

And here is the point: almost no one operates it as what it is.

The cost of operating in multiple currencies as if they were just one

Most manage this puzzle as a sum of administrative tasks. Every international payment, an instruction to the bank. Every conversion, at whatever exchange rate applies that day. Every month-end close, a manual reconciliation to understand (too late) how much was lost along the way.

That cost does not appear on any invoice. It appears on the margin.

It gets lost in the spread of each conversion you did not choose. In the days that money spends frozen between when you collect and when you pay. In not being able to see, in a single place, how much comes in in dollars and how much goes out in yuan or euros.

I wrote recently that selling more is not the same as earning more, and that the margin is guarded in foreign exchange exposure. This is the next chapter of that idea. Because the exposure of a Mexican company is no longer just peso-dollar. It is peso-dollar-yuan-euro, all at the same time.

What you can control

You do not control where global trade reorganizes itself. You do not decide that your most competitive suppliers are in Asia. You do not move the exchange rate.

But you do control three things:

1. Which currencies you operate in, and from where. Receiving dollars and paying in the supplier's currency from the same account, without bouncing the money through three banks.

2. When you convert. Not exchanging out of urgency on the day you have to pay, but when it makes sense for your margin.

3. How clearly you see it. Knowing at all times how much you have in each currency and where it is going, without waiting for the month-end close.

That is how you stop suffering the multi-currency reality and start operating it.

Mexico, a transit point

Mexico stopped being just a country that exports. It has become a transit point for global money: it comes in from the north, is transformed here, goes out to the east, and returns.

For the country, it is a massive position. For your company, it is a decision that has largely already been made for you, except for what matters most: who operates that transit of money. Your company, with control, or your bank, by default.
