Why Mexico’s ‘Super Peso’ May Face A Rougher Ride Before The 2026 USMCA Review

For the past two years, Mexico has looked like a surprise winner in global markets. While many emerging currencies wobbled, the peso strengthened so much that traders started calling it the “super peso.”

For expats and foreign investors, Mexico suddenly felt like a safe, rules-based gateway into North America. Now the people who watch the economy most closely are sounding more cautious.

Mexico’s association of finance executives, IMEF, says the peso is “artificially” stable because the dollar has been weak, not because Mexico suddenly became an economic powerhouse.

They expect the exchange rate to drift from around today’s levels to about 18.80 pesos per dollar at the end of this year and toward 19.50 next year.

Their growth forecasts are modest too: just 0.5% in 2025 and 1.3% in 2026. The real story, however, lies in a quiet line of legal text called the USMCA review clause.

When the updated North American trade agreement replaced NAFTA in 2020, it came with a mandatory check-up every six years, starting in 2026, and a 16-year expiry date if the three countries cannot agree to extend it.

USMCA review tests Mexico’s trade predictability

On paper, that review is meant to keep the pact modern and balanced. In practice, it opens the door to political brinkmanship: demands for tougher labor rules, stricter environmental conditions, or new industrial policies that can disrupt the very predictability investors need.

Mexico’s export engine, especially autos and manufacturing built around “nearshoring,” depends on stable, low-tariff access to the US and Canadian markets. Every hint of new tariffs or moving the goalposts on trade rules makes the peso more vulnerable.

A weaker currency would help some exporters and families receiving remittances in dollars, but it would also make imported food, fuel and technology more expensive for ordinary Mexicans and foreign residents alike.

For expats, multinationals, and Brazilian companies looking north, the takeaway is straightforward: Mexico remains a serious production base.

However, the strength of the “super peso” will ultimately reflect something more fundamental than market hype — whether leaders keep trade predictable, disciplined, and open, or allow short-term politics to unsettle the rules of the game.
