Summary: This article tackles a question lots of folks in international trade or travelers often wonder about: How does the Mexican peso stack up against other major Latin American currencies when measured against the US dollar? I’ll use recent data, give you practical examples, include an expert’s take, and even dive into some sometimes-forgotten details I learned the hard way. I’ll also compare how different countries verify and treat “trade” according to official rules, offering a practical table rooted in recognized standards and direct sources.
Why Compare Currencies? The Real-World Value
I found myself asking this recently after I sent some money to a friend in Argentina and was surprised by how many extra pesos showed up on her end. I’d always assumed all Latin American currencies lost out the same way to the dollar, but—newsflash!—the story is way more complicated, and the Mexican peso (MXN) is actually kind of a superstar lately.
Whether you run an import business, send remittances, or just enjoy traveling, keeping tabs on exchange rates isn’t just “finance geek stuff.” Currency moves shape everything from the cost of avocado toast in Brooklyn to labor wages in Guadalajara. So, let’s dig in—with a mix of hard facts, some screenshots (just check XE.com or Bloomberg for the latest), and a bit of my personal learning curve. And yes, we’ll take detours when it gets dull, because, honestly, who actually loves checking currency charts?
Step 1: Look at the Data — Comparing Peso to Other Latin Amercian Currencies
First, some hands-on, real data. For comparison, let's pull up the five major Latin American currencies most often mentioned alongside the peso:
- Mexican Peso (MXN)
- Brazilian Real (BRL)
- Argentine Peso (ARS)
- Chilean Peso (CLP)
- Colombian Peso (COP)
Open your browser and go to XE Currency Charts or Bloomberg Currency. Select USD as your base, and then each currency above. Here's what my screen looked like (imagine this picturing the last six months up to June 2024):

What do you see? The main thing that jumps out (and caught me off guard the first time): the Mexican peso stayed surprisingly strong against the dollar compared to the BRL, CLP, ARS, and COP. The ARS (Argentine peso), in particular, is in freefall—no joke, a couple times I thought my screen glitched, but it’s just their financial reality.
Practical Comparison Table: Year-to-Date Exchange Rate Movements (2024)
| Currency | 2024 Change vs USD (%) | Current USD Rate (Jun 2024) | Key Comments |
|---|---|---|---|
| MXN – Mexican Peso | +2.7% | ~17.2 MXN = 1 USD | Most stable, even strengthening slightly |
| BRL – Brazilian Real | -6.1% | ~5.5 BRL = 1 USD | Weaker, volatile with political changes |
| CLP – Chilean Peso | -4.7% | ~925 CLP = 1 USD | Volatile, weakened in early 2024 |
| COP – Colombian Peso | -5.2% | ~4,125 COP = 1 USD | Weakened after strong 2023 |
| ARS – Argentine Peso | -48% (official), far worse parallel | ~900 ARS = 1 USD (official); ~1,200 (blue) | Major collapse; dual market rates |

Small story: Last time I paid a Mexican freelancer, he told me his earnings grew in dollar terms over the year—while my Argentine friend lost half her real purchasing power. That sort of day-to-day impact really puts the chart above into perspective!
Step 2: The "Why" Behind Peso's Relative Strength
This is where my pragmatic, slightly-skeptical side kicks in: why is the Mexican peso doing so much better than its neighbors? In one interview, Gabriel Lozano (Chief Economist at J.P. Morgan Mexico) said, “The peso is liquid, heavily traded, and benefitting from nearshoring—factories moving from Asia to Mexico. Investors see pesos as a safe-ish bet in Latin America.” (Reuters, July 2023)
Exchange rates are driven by:
- Interest rates and central bank policy (Mexico kept higher rates, attracting capital); see Banxico
- Political and economic stability (Mexico’s elections caused some blips, but overall, it's steadier than Argentina or Chile)
- Trade relationships with the US (USMCA effect; increased trade volume)
- Speculation/market liquidity (the peso is the most traded in LATAM, so it's less prone to sudden slides)
By contrast, Argentina’s currency fell off a cliff due to runaway inflation and controls (check the daily drama on Dólar Hoy!), while Brazil sees swings every election cycle.
One time I exchanged pesos in Mexico City, and the rate changed during the transaction due to a central bank announcement. The point? Even a "stable" currency like the peso can get rocky with the right (or wrong) newsflash.
Industry Context: "Verified Trade" Standard Differences Across LATAM
While we're talking currencies and cross-border deals, it's crucial to note international trade doesn't always mean the same thing, legally or practically, everywhere. Here's a table I pulled together, comparing standards for "verified trade" (often key for customs, WTO, and anti-fraud enforcement)—this gets surprisingly bureaucratic!
| Country | Legal Definition | Key Law/Document | Regulatory Authority |
|---|---|---|---|
| Mexico | Commercial exchange with legal documentation and SAT approval | Customs Law Art. 36–51, SAT Guidance (SAT) | SAT (Mexican Tax Administration Service) |
| Brazil | Legally registered import/export, documented and reported to Receita Federal | Customs Law (Lei 10.637/2002), IN 1227/2012 | Receita Federal do Brasil |
| Argentina | Registered, fiscalized cross-border exchanges | Código Aduanero, AFIP Reg. | AFIP (Federal Administration of Public Revenue) |
| Chile | Trade with certified customs and SII documentation | Ley de Aduanas, SII protocols | SII (Internal Revenue Service), Aduanas |
| OECD / WTO (standard) | Documented supply of goods/services, invoice and customs declaration | WTO Customs Valuation Agreement (WTO) | National Customs + WTO supervision |

Case Study: Mexico vs. Brazil in Dispute Over Verified Trade
Say Company A (Mexico) sells car parts to Company B (Brazil). If a shipment is delayed and B wants to delay payment, it may claim “unverified” trade because their Receita Federal office lacks certain e-docs that SAT in Mexico already approved. According to trade lawyer Alfredo Nava (from a conference I attended), “such disputes often hinge on differences in invoice validation—Mexico prioritizes SAT digital seal, Brazil wants Receita Federal registry. A shipment could be legitimate in Mexico and flagged in Brazil just for missing a code, risking a tariff or even a fine.”
This actually happened to a friend—I had to help them fax (yes, fax) extra paperwork to São Paulo. The headaches of mismatched standards!
What Do Central Banks and Global Authorities Say?
Both IMF and OECD exchange rate trackers note the peso’s outperformance in 2023–2024, especially compared to the ARS and BRL. The Banco de México regularly reports “peso stability” and increased trade with the United States as key factors. Meanwhile, the WTO’s customs valuation rules (see the WTO Customs Valuation Agreement) allow some local flexibility—but the more “verified” your paperwork, the more likely you’ll get quick customs clearance.
My Take: Lessons Learned and Currency “Fit”
So, is the Mexican peso stronger or weaker than major LATAM currencies against the dollar? Recent, verifiable data shows—despite a volatile world—the MXN is, hands-down, the strongest and steadiest Latin American currency over the past year. It hasn’t just resisted devaluation; it's become the “favorite child” of international capital and pragmatic businesspeople.
If you’re trading, investing, or just traveling, the peso’s stability is a real practical advantage. But relying too much on any currency is risky (speaking from experience—remember that “stable” Turkish lira?). Watch out for regulatory snags like mismatched customs docs, especially if you’re bridging Mexico, Brazil, and Argentina. Double-check paperwork, use real-time currency tools, and—frankly—stay skeptical when things look “too stable,” as currency fortunes can turn on a dime.
Conclusion & Next Steps
Quick recap: The Mexican peso is, as of mid-2024, the strongest and most stable currency in Latin America versus the dollar—outshining Brazil, Chile, Colombia and Argentina by a wide margin. Verified trade practices and currency legalities can vary massively across borders, with each country’s tax and customs authorities enforcing slightly different documentation for proof. Always cross-check the latest legislation (such as the Mexican Customs Law) for up-to-date requirements. And because real life always trumps textbook learning, ask around, check today’s rates (XE.com), and learn from others’ headaches (or your own).
Next steps—if you’re moving money, trading, or planning business abroad in Latin America, start with a double-check of your home bank’s FX rates, scan your customs requirements, and keep an eagle eye on both official and practical (on-the-ground) obstacles. The world of pesos isn’t perfect—but it’s a lot more robust than you might expect!
