When sending money home or running a cross-border business, the story of how the Mexican peso stacks up against the US dollar—and, crucially, against its Latin American cousins like the Brazilian real, Chilean peso, Argentine peso, and Colombian peso—isn’t just about numbers. It’s about real-world impact. This article unpacks how the Mexican peso compares to other major regional currencies, drawing on live data, regulatory frameworks, and a few personal misadventures in banking and trade. If you’ve ever felt lost watching exchange rates bounce and wondered what’s really driving these swings, you’re in the right place.
Let me set the scene: A few years back, I was helping a small business expand its e-commerce operations to Mexico, Brazil, and Chile. Every week, I’d nervously watch the exchange rates on XE.com and Bloomberg, trying to figure out where best to hold our working capital.
One day, I tried to pay a supplier in Brazil. The real had just dipped against the dollar, while the Mexican peso was holding surprisingly firm. My initial assumption (and, I’ll admit, a rookie mistake) was that all Latin American currencies would move in lockstep against the US dollar. Spoiler: They don’t.
That week, our cash flow planning basically imploded, and I spent two days reading up on central bank policies, trade balances, and those “currency wars” you sometimes hear about in financial news. If you’re navigating the same choppy waters, this breakdown is for you.
Let’s ground this in actual data. According to Reuters, the Mexican peso (MXN) was Latin America’s best-performing major currency versus the dollar in 2023, appreciating around 14% year-to-date at one point. This was in sharp contrast to the Argentine peso—which suffered massive devaluation—and the Chilean peso, which was volatile due to political and economic headwinds.
Here’s a quick, recent snapshot (late 2023 to early 2024):
For the latest numbers, I usually check XE.com and overlay the different currencies’ charts for a reality check. The differences can be striking.
Several factors explain the peso’s relative strength:
In contrast, countries like Argentina and Chile have faced political shocks, commodity price swings, and, in Argentina’s case, hyperinflation. As a result, their currencies have struggled.
If you’re exporting goods or managing cross-border payments, the way each country manages “verified trade” and currency controls can have a big impact. For instance, the IMF’s Article IV report on Mexico repeatedly emphasizes the country’s strong external position and flexible exchange rate regime.
Meanwhile, Argentina’s central bank (BCRA) imposes capital controls and multiple exchange rates, leading to a huge divergence between official and “blue market” pesos. Brazil and Chile are more open, but both have interventionist histories.

|---|---|---|---|
| Mexico | Flexible FX, open capital account | Bank of Mexico Law; IMF Article IV | Bank of Mexico (Banxico) |
| Brazil | Managed float, FX regulations for trade | Resolution 3,568/08 (BACEN) | Central Bank of Brazil (BACEN) |
| Chile | Liberal FX, capital controls lifted | Central Bank Law 18,840 | Central Bank of Chile |
| Argentina | Multiple exchange rates, strict controls | BCRA Communication "A" 7030 | Central Bank of Argentina (BCRA) |
| Colombia | Managed float, some controls | Resolution 8/2000 (Banco de la República) | Banco de la República |

Here’s a real (if anonymized) case from a trade group I worked with: A Mexico-based auto parts exporter tried to bill a client in Argentina in US dollars. The Argentine client insisted on paying in pesos at the official rate—except, with capital controls, dollars were nearly impossible to access. The payment ended up stuck for weeks, and the exporter took a painful haircut when converting at the “blue market” rate.
An Argentine trade consultant we interviewed explained, “In Mexico, you can move dollars with minimal paperwork. In Argentina, every transaction is scrutinized, and the effective exchange rate can be 2x different. It’s not just about the peso being weaker—it’s about what you can actually do with your money.”
I recently chatted with Lucia M., a currency risk advisor in São Paulo. Her advice: “Don’t assume the peso’s strength is permanent. Brazil’s real can swing suddenly if commodity prices rise. But Mexico is the current favorite for US investors—just watch for any policy shifts after elections.”
In sum, the Mexican peso has been notably stronger and more stable than other major Latin American currencies against the US dollar over the past year or so, driven by high interest rates and investment flows. But it’s not bulletproof: political risk, US Fed policy, and global shocks can flip the script fast. If you’re working, investing, or sending money between Latin America and the US, don’t just look at headline rates—dig into local controls, trade standards, and actual payment friction. That’s where the true story lies.
For next steps, I’d suggest following the IMF’s Mexico country page and checking each central bank’s site for regulatory updates. If you’re a business, consider professional FX risk advice. If you’re just sending remittances, check platforms like Wise or Remitly for live rates and hidden fees.
And if you ever find yourself staring at a spreadsheet of exchange rates at midnight, remember: you’re not alone.
