MEXICO · TRADE & MONEY

Key Facts

—The country Mexico has about 132 million people and an economy of about US$1.83 trillion in 2025 (World Bank), slightly smaller than Spain’s. It is tied to the US and Canada by the USMCA trade pact.
—The calendar The fourth formal round of US–Mexico trade talks is slated for Washington on Monday 28 September and Tuesday 29 September.
—The table US duties on Mexican steel and aluminum (50 percent), cars and auto parts (25 percent), and goods that fail the USMCA’s origin rules.
—The negotiators US Trade Representative Jamieson Greer leads for Washington; Economy Secretary Marcelo Ebrard leads for Mexico City.
—The background This is the fourth round of the ongoing USMCA review; the third round, in Mexico City in July, produced public progress on cars, steel and aluminum, agriculture, labor and economic security.
—The market The peso closed Friday at 17.6760 per US dollar (MXN 10,000 ≈ US$566); it traded near 17.15 after the leaders’ phone call on 16 September.
—What it means for you The result can move the peso and the prices of cars and imported goods; a weaker peso stretches dollar incomes further in Mexico.
—Still open Whether the round produces an agreement, what Congresses on both sides must then ratify, and whether the tariff relief is broad or sector-by-sector.

After a postponed round and a presidential phone call, the United States and Mexico sit down in Washington on Monday with tariffs on Mexican steel, aluminum and cars on the table. For expats, the outcome lands on everything from car prices to the peso in your pocket.

What Is on the Table

The talks are the fourth formal round of the review of the USMCA, the trade pact that governs most US–Mexico commerce. According to Politico and Al Jazeera, Mexico is seeking tariff relief for its steel, aluminum and car industries — the sectors Washington hit with duties of 50 percent and 25 percent respectively — along with smoother treatment of goods that fail the agreement’s origin rules. After the third round in Mexico City in July, both sides publicly cited progress across cars, steel and aluminum, agriculture, labor and economic security.

Why This Round, and Why Now

The round was originally expected a week earlier and was postponed after President Trump and President Sheinbaum spoke by phone on 16 September; officials on both sides described the talks as active and moving in a positive direction. The USMCA itself is up for review, and the threat hanging over the negotiation has been a broader tariff hike — reported since late 2025 at up to 30 percent if the review produces no deal. Monday’s session in Washington is the first time the negotiators meet with that clock explicitly in view.

What It Means for Expats’ Money

The peso. The currency is the first transmission line: it traded near 17.15 per dollar after the leaders’ call, then drifted weaker over the following week, closing Friday at 17.6760. A deal with real tariff relief tends to support the peso; a collapsed round does the opposite — expect MXN to move on headlines through Tuesday. Prices. Tariffs on cars, steel and aluminum feed into Mexican consumer prices for vehicles, appliances and construction; relief would slowly damp that pressure. Remittances and rents. A stronger peso means dollars sent from the US buy fewer pesos; a weaker one does the reverse — worth a minute’s thought if your income is in one currency and your life in the other.

If There Is a Deal — and If There Is Not

An agreement in principle would still face ratification steps on both sides, and the details — which sectors, what timelines, what enforcement — will matter as much as the headline. If the round ends without one, the default is the status quo plus escalation risk: the threatened broader tariffs stay live, and the peso carries that risk into October. Either way, the near-term effect on daily expat life is indirect but real: this is a week to watch the exchange rate before moving large sums. Our Banxico standalone covers the rate backdrop, and the daily guide for Sunday 27 September tracks the week.

When are the US–Mexico trade talks, and where?

The fourth formal round opens on Monday 28 September in Washington and runs through Tuesday 29 September. US Trade Representative Jamieson Greer leads the US side; Economy Secretary Marcelo Ebrard leads Mexico’s. The round was postponed by a week from its original date after the Trump–Sheinbaum phone call on 16 September.

What tariffs are actually being negotiated?

According to Politico and Al Jazeera, the Mexican agenda centers on US duties of 50 percent on steel and aluminum and 25 percent on cars and auto parts, plus treatment of goods that fail the USMCA’s origin rules. A broader tariff increase — reported since late 2025 at up to 30 percent if the review fails — has been threatened, which is the pressure point behind the round.

Does the outcome change anything for my daily budget in Mexico?

Not overnight. Tariff relief would ease price pressure on cars, appliances and building materials over months; a failed round keeps escalation risk alive and tends to weigh on the peso. In the short run the visible effect is the exchange rate: MXN 10,000 is about US$566 at Friday’s close, and the rate can move a percent or two on headlines from Washington. If you are converting a large amount, waiting out the two talk days is a reasonable option.
