How is the exchange rate today?

Where to find the live USD/MXN rate

• Investing.com shows a live rate around 17.5598 and a previous close of 17.5101.
• Xe reports a mid-market rate of 17.4793 at 14:52 UTC.
• Wise shows a mid-market rate of about 17.56 MXN.

What is the difference between buy and sell rates?

The buy rate is what a bank or exchange house pays for your dollars; the sell rate is what they charge you for pesos. The gap between them is the spread — the institution’s profit. For example, Banamex might buy at 17.20 and sell at 17.80, a spread of 0.60 pesos per dollar.

How often does the official Banxico rate update?

Banco de México publishes the FIX exchange rate once per banking day at 12:00, based on wholesale FX quotations. The closing rate is computed at 2:10 p.m. from a weighted average of a random three-minute sample within a ten-minute window starting at 1:55 p.m.

The implication: always verify the rate that applies to your transaction before committing to an exchange.

How much is it to change dollars to pesos?

Using a currency converter for USD to MXN

Simply multiply the dollar amount by the current exchange rate. For example, $100 USD × 17.58 = 1,758 MXN (at the market mid-rate). Tools like Xe and Wise provide the mid-market rate, but the actual amount you receive will be less due to fees and spreads.

How to calculate the amount you will receive

If you are exchanging at a bank, use the bank’s sell rate (the rate at which they sell pesos). For $100 USD at a sell rate of 17.80, you get 1,780 MXN. But if the bank’s buy rate is 17.20, that means they are buying dollars from you at 17.20 — so you would get 1,720 MXN. Always use the rate that applies to your transaction.

What fees are included in the exchange rate?

Banks and exchange houses add a markup to the mid-market rate. This is often hidden in the spread. Online services like Wise charge a transparent fee. Some physical locations also charge a commission on top of the spread.

The pattern: the bigger the spread, the more you lose per dollar exchanged.

What is the best place to change dollars to pesos?

Comparing exchange rates at Mexican banks vs. currency exchange booths

• Mexican banks like Banamex and Banorte offer competitive rates for account holders, with buy rates around 17.20–17.40.
• Currency exchange booths in tourist areas often have worse rates, sometimes with spreads exceeding 1 peso per dollar. For a comparable guide on another currency, see our analysis of the US Dollar to Rupee Rate Today: Why INR is Falling & Forecast.

Online platforms like Wise vs. physical locations

Wise and Revolut use the mid-market rate with a small upfront fee, often beating physical exchange rates. For example, sending $1,000 USD via Wise might yield around 17,560 MXN, while a bank branch could give only 17,200 MXN — a difference of 360 pesos.

How to avoid high commissions and hidden fees

• Avoid exchanging at airports or hotels.
• Use a fee-free ATM card from a Mexican bank or a global account like Wise.
• Always ask for the total cost in pesos before agreeing to an exchange.
• Consider using online platforms with transparent fee structures.

The catch: convenience at airports or hotels carries a hidden tax of up to 5% per transaction.

Choose the right exchange method

• Use Wise or Revolut for online transfers — they offer mid-market rates with low fees.
• Withdraw from ATMs that are part of a major bank network, but avoid dynamic currency conversion.
• Compare buy and sell rates at multiple banks before exchanging cash.

Watch out for hidden fees

Some services advertise a “0% commission” but make up for it with a wide spread. For example, a booth that offers 17.00 MXN per dollar when the market is 17.58 is effectively charging a 3.3% fee. Always convert the rate you get to a percentage of the mid-market rate.

The implication: for amounts over $500, the savings from using a bank or online service can exceed $20 USD.

Five common exchange methods, one pattern: the spread determines the real cost.

Is it dollar or peso?

Understanding the difference between USD and MXN

The United States dollar (USD) and the Mexican peso (MXN) are two distinct currencies. The peso symbol ($) is used for both, which causes confusion. In Mexico, prices are often labeled with “$” but the currency is pesos. When you see “$100” in Mexico, it means 100 pesos, not 100 dollars.

Why the peso symbol ($) can be confusing

Both currencies use the same symbol. To avoid mistakes, look for the ISO code (MXN or USD) or the context. Online converters and bank statements always use the three-letter code.

How to distinguish between Mexican pesos and other peso currencies

The Mexican peso is often written as MXN, while Argentine pesos use ARS and Chilean pesos use CLP. The exchange rate for each is different. Always check the currency code when converting.

What is the official dollar rate at Banco Nación Argentina?

How the official rate differs from the blue dollar rate

Argentina’s central bank sets an official exchange rate that is typically lower than the parallel “blue dollar” rate. The gap reflects capital controls and restricted access to foreign currency.

Accessing the official exchange rate from Banco Nación

Banco Nación publishes its daily exchange rate on its website. The rate is updated regularly and serves as the benchmark for many official transactions.

Why Argentine peso rates are volatile

High inflation, political uncertainty, and foreign reserve challenges cause rapid shifts in the Argentine peso’s value. These conditions are specific to Argentina and not directly comparable to the Mexican peso.

How to Convert Dollars to Pesos: Step-by-Step Guide

1. Check the mid-market rate on Xe or Wise.
2. Decide your method — bank, online transfer, ATM, or cash exchange.
3. Compare the buy rate (if selling dollars) or sell rate (if buying pesos) at your chosen institution.
4. Calculate the total cost including any fees. Multiply the dollar amount by the applicable rate.
5. Execute the exchange — for online transfers, initiate the transfer; for cash, visit the bank or ATM.
6. Confirm the amount received in pesos and compare it to the mid-market rate to see the real cost.

The pattern: each step closes the gap between the advertised rate and what you actually receive.

The catch: no single method is perfect; the best choice depends on your specific transaction size and location.

The implication: always cross-check the rate you receive against the mid-market rate at the time of transaction.

The pattern: both the central bank and commercial services agree that the spread is the key variable for consumers.

For travelers and remittance senders, the choice is clear: use an online service like Wise for the best rate on transfers, or a Mexican bank account for cash withdrawals. Avoid tourist exchange booths and airport counters unless you are willing to lose 3–5% on every dollar. The peso’s value will fluctuate, but the cost of convenience is always a spread.
