The Dollar Exchange Rate in Mexico Today: A Simple Guide for August 20, 2026
What Is Happening with the Dollar Today?
Imagine you want to trade your US dollars for Mexican pesos (or vice versa). The "price" of the dollar changes every day, just like the price of apples or gasoline.
On Thursday, August 20, 2026, the official reference rate is 16.95 pesos for 1 US dollar. But depending on where you exchange your money, you might get a slightly different deal. This guide breaks down the numbers so you know exactly what to expect.
The "Official" Rate: What the Central Bank Says
The Banco de México (Banxico)—Mexico’s central bank, like the Federal Reserve in the US—publishes the official reference rate every day.
Important Point: How is this number calculated?
Banxico doesn’t just pick a number. They calculate an average of the rates used by big banks and financial institutions in the wholesale market (where huge amounts of money are traded). These are for transactions that settle in two business days. They pull this data from electronic trading platforms that represent the real market.
The Official Rate for Today: 16.95 MXN per 1 USD
Rates at Commercial Banks: Buying vs. Selling
When you walk into a bank branch, you will see two prices. Banks make money on the difference (the "spread").
Banamex (Citibanamex) Rates Today
| Action | Rate (Pesos per Dollar) | What This Means for You |
|---|---|---|
| Bank Buys Dollars | 16.41 | You sell your dollars to the bank. You get fewer pesos. |
| Bank Sells Dollars | 17.35 | You buy dollars from the bank. You pay more pesos. |
ELI5 Explanation: Think of the bank like a used car dealer. They buy your car (dollars) for a low price (16.41) and sell it to the next person for a high price (17.35). The difference is their profit for providing the service and taking the risk.
Sending Money Home: Remittance Rates
If you are sending money from the US to family in Mexico (remittances), you don’t use the "official" rate or the bank counter rate. You use a money transfer company. Each company sets its own rate.
Here is what the major players are offering today for sending USD to MXN:
1. Western Union
- Rate: 17.22 MXN per 1 USD
- Your recipient gets 17.22 pesos for every dollar you send.
2. MoneyGram
- Rate: 17.31 MXN per 1 USD
- Slightly better than Western Union today.
3. Wise (formerly TransferWise)
- Rate: 16.82 MXN per 1 USD
- Note: Wise often charges a low, transparent fee upfront but uses a rate closer to the "mid-market" (official) rate. The others might hide fees inside a worse exchange rate.
Pro Tip: Always check the TOTAL AMOUNT RECEIVED. A company advertising "Zero Fees" might give a terrible exchange rate (like 16.50), while one charging a $5 fee might give 17.30. Do the math:
Dollars Sent × Exchange Rate = Pesos Received.
The "Super Peso": Why a Strong Currency Isn’t Good for Everyone
Since 2023, the Mexican peso has been very strong against the dollar (trading around 16-17 pesos per dollar). People call this the "Super Peso."
While it sounds great—"Our money is worth more!"—it creates winners and losers.
Who Loses with a Strong Peso?
-
Families Receiving Remittances
- Scenario: Your uncle in the US sends $300.
- At 20 pesos/dollar (Old rate): You get 6,000 pesos.
- At 16.95 pesos/dollar (Today’s rate): You get 5,085 pesos.
- Result: You lost 915 pesos of buying power for the exact same $300 sent. If this continues all year, families lose significant purchasing power.
-
People Paid in Dollars, Living in Mexico
- Remote workers, freelancers, and retirees with US pensions see their local income shrink.
- Example: A $3,000/month pension bought 60,000 pesos before; now it buys ~50,850 pesos. Rent and groceries in pesos didn’t get cheaper, but the dollar income did.
- Exporters & Border Tourism
- Mexican factories selling goods to the US get fewer pesos for their dollars.
- US tourists find Mexico "more expensive" because their dollars buy fewer pesos, potentially reducing cross-border shopping and tourism.
Who Wins?
- Importers: Buying US machinery, tech, or grain is cheaper in peso terms.
- Mexican Travelers to the US: Your pesos go further in Dallas or Miami.
- Debt Payments: The government and companies with dollar-denominated debts pay less in pesos to service them.
Summary: Key Takeaways for Today
- Official Rate (Banxico): 16.95 MXN/USD (The benchmark average).
- Banamex (Bank Counter): Buy at 17.35 | Sell at 16.41 (Widest spread, convenient for cash).
- Remittances (Best for sending money home):
- MoneyGram: 17.31 (Best rate today)
- Western Union: 17.22
- Wise: 16.82 (Low fees, transparent pricing)
- The "Super Peso" Context: The peso has been strong since 2023. This hurts remittance recipients and dollar-earners in Mexico by reducing the peso value of their dollars.
Frequently Asked Questions (FAQ)
1. Why is the Banxico rate (16.95) different from the bank rate (17.35)?
The Banxico rate is a wholesale average for big institutions settling in 2 days. Banks add a markup (spread) to cover costs, risk, and profit for giving you cash instantly over the counter.
2. Which service should I use to send money to Mexico?
Compare the "Total Received." Today, MoneyGram (17.31) gives the most pesos per dollar among the three listed. However, check fees! If MoneyGram charges $10 fee and Wise charges $4, Wise might win on smaller amounts. Always calculate: (Dollars - Fees) × Rate = Final Pesos.
3. Will the "Super Peso" last forever?
No currency stays strong forever. It depends on interest rates (Banxico vs. Fed), oil prices, US economy health, and investor confidence. Most analysts expect some weakening eventually, but timing is impossible to predict.
4. I get paid in dollars but live in Mexico. How do I protect myself?
- Don’t convert all at once: Dollar-cost average (convert a bit every week/month).
- Keep a USD account: Use a bank (like Wise, or a US bank account) to hold dollars and only convert what you need for monthly expenses.
- Invest in peso assets: If you have savings, peso-denominated government bonds (Cetes) pay high interest rates (~10-11%), which can offset currency loss.
5. Is the "Tipo de Cambio FIX" the same as the rate I see on Google?
Yes, usually. The FIX rate (published by Banxico at 12:00 PM CT) is the official legal rate for tax and accounting purposes. Google/financial apps usually show the Spot Rate (current market price), which is very close to FIX but fluctuates by the second during market hours.
