Honestly, if you looked at a spreadsheet back in late 2024, you would have bet your house against the Mexican currency. Most of the "smart money" was screaming that a second Trump term would absolutely crater the exchange rate. We’re talking 22 or 25 pesos to the dollar. But here we are in mid-January 2026, and the peso mexicano trump fed triangle is doing something nobody—and I mean nobody—really saw coming.
The peso is sitting at roughly 17.65. It's wild.
We’ve got a U.S. President who thinks "tariff" is the most beautiful word in the dictionary. We have a Federal Reserve that’s basically in a cold war with the White House. And yet, the Mexican peso is acting like it’s made of titanium. Why? Because the relationship between the peso mexicano trump fed isn't as simple as "Trump tweets, peso falls" anymore. The mechanics have shifted.
The Trump Tariff Reality Check
When Donald Trump took office again, he didn't wait. On day one, he signed that memorandum to review migration and fentanyl, threatening 25% tariffs on Mexico. The market flinched for a second, but then it realized something. Mexico is now the top trading partner of the U.S., and untangling that web is messy.
A 25% tariff on a car made in Puebla doesn't just hurt Mexico. It destroys the supply chain for companies in Michigan and Ohio. Investors have started to bet that Trump’s "art of the deal" style means these tariffs are more like a starting offer in a high-stakes poker game rather than a permanent wall.

You've got the 2026 USMCA review looming over everyone's heads. It’s officially underway as of this month. Economy Minister Marcelo Ebrard is out there trying to play the "Trump whisperer" role, and so far, it's working well enough to keep the currency from spiraling. The markets are banking on the idea that the USMCA is too big to fail. If Trump actually kills it, we’re in uncharted territory, but for now, the "Super Peso" is holding its ground because the alternatives—like China—are even more in the crosshairs.
Why the Fed is the Peso's Secret Weapon
While Trump is the loud part of the peso mexicano trump fed equation, the Fed is the engine room. Jerome Powell is in a tough spot. Trump has been openly calling for aggressive rate cuts, basically trying to bully the Fed into juice-loading the economy.
At the December 2025 meeting, the Fed cut rates by 25 basis points, bringing the range to 3.50% to 3.75%. But here’s the kicker: Banxico (Mexico’s central bank) is still holding their rates way higher, around 7%.
That gap is a vacuum for cash.

Investors love a "carry trade." Basically, they borrow money where it’s cheap (the U.S.) and park it where the interest is high (Mexico). As long as the Fed keeps cutting or staying neutral while Banxico stays tough, the peso has a floor. Even if Trump says something spicy on Truth Social, that 3% to 4% interest rate differential is a lot of "insurance" for a hedge fund manager to ignore.
The 2026 USMCA Review: The Real Boss Battle
We’re currently in the middle of the mandatory six-year review of the trade pact. This is the biggest risk for the peso mexicano trump fed dynamic this year. Trump has called the agreement "not relevant," which is classic Trump branding. He wants to renegotiate, not just review.
He’s looking for:
- Higher regional content rules for cars (basically forcing more parts to be made in the U.S.).
- Stricter labor enforcement.
- Deals that stop Chinese companies from using Mexico as a "back door" into the American market.
If these negotiations go sideways before the July 1 deadline, the peso could see a 10% swing in a single afternoon. But right now? The market is surprisingly calm. There's this weird sense of "we've been here before." People remember 2016. They remember the threats to end NAFTA. In the end, a deal got signed.

What Most People Get Wrong About Mexico’s Economy
Don't get it twisted—Mexico’s actual internal economy isn't doing great. GDP growth for 2025 was under 1%. Unemployment hit 4.6% recently. In a normal world, a country with slow growth and rising unemployment should have a weak currency.
But the peso mexicano trump fed connection isn't about Mexico's internal health. It’s about global geopolitics.
Mexico is the ultimate "nearshoring" play. As the U.S. tries to decouple from China, Mexico is the only place that can pick up the slack. Even with the tariffs, a factory in Monterrey is more attractive than a factory in Shenzhen because of the proximity and the existing trade framework.
Actionable Insights for 2026
If you're holding pesos or doing business across the border, you can't just look at the news. You have to look at the math.
- Watch the Spread: If the Fed stops cutting and Banxico starts slashing rates to save their slow economy, the peso will drop. That interest rate gap is the only thing keeping the "Super Peso" alive right now.
- Ignore the Rhetoric, Watch the Implementation: Trump will threaten a 50% tariff on steel or aluminum. Watch if it actually happens or if it’s a "negotiation delay." The peso usually recovers quickly from the tweets but stays low if the policy actually sticks.
- The July 1 Deadline: Mark this on your calendar. This is the "drop dead" date for the USMCA review. Expect massive volatility in the peso mexicano trump fed relationship starting in late May.
- Hedge for the 19.50 Mark: Most analysts, including those at Citi and Reuters, think the peso will eventually settle around 19.00 or 19.50 by the end of 2026. The current strength at 17.65 is likely a peak. If you need to buy dollars, now is probably the time.
The reality is that we are living in a world where the old rules of economics are being rewritten by political willpower. The peso mexicano trump fed saga is the perfect example of that. It’s a mix of high-interest rates, trade threats, and the cold reality that the U.S. and Mexico are stuck with each other, for better or worse.
If you are waiting for a "return to normal," you might be waiting a long time. The new normal is volatility, and the best way to handle it is to keep your eye on the Federal Reserve’s dot plot while keeping your notifications on for the White House press releases.
