Interbank rate: 17.36 MXN per USD (Oct 2023) ·
Bank buy range: 16.50 – 17.00 ·

The table below summarizes the exchange rates across various channels.

¿Cuánto vale $1 dólar en México hoy?

The short answer: one US dollar buys between roughly 16.50 and 18.00 Mexican pesos, depending on where you exchange it. The official interbank rate, published daily by Banco de México (Mexico’s central bank), was 17.36 in October 2023. But individuals almost never get that rate—banks add a spread for buying and selling.

Tipo de cambio interbancario actual

• Interbank rate: 17.36 MXN per USD (October 2023) – Banxico SIE market data
• This rate is used for large financial transactions, not for cash exchange.

Tasas de compra y venta en bancos principales

Mexican banks set their own buy and sell rates each business day. For example, Banamex offered a buy rate near 16.80 and a sell rate near 17.90 in the same period. BBVA and Santander publish similar ranges. The gap between buy and sell (the spread) is typically 1.00–1.50 MXN, representing the bank’s profit.

The pattern: spreads remain stable, making bank cash exchanges predictable.

¿Qué bancos pagan mejor el dólar en México?

Three leading banks dominate the retail exchange market. Their rates are close, but small differences can add up when converting larger amounts.

Rates are approximate for late 2023 based on published online data from Banamex, BBVA, and Santander. Always check the bank’s live rate before transacting.

The pattern: Banamex offers the highest buy rate (best for you when selling dollars), while BBVA has the lowest sell rate (best when buying dollars). Santander sits in between. BBVA Research notes that retail spreads at Mexican banks have remained stable, reflecting a competitive but profitable market for currency exchange.

¿Cuánto es $100 dólares en México?

Let’s put the numbers into a concrete example. Converting 100 US dollars yields different amounts depending on the rate you get.

• At the interbank rate of 17.36, 100 USD = 1,736 MXN — but you cannot get this rate directly.
• At a typical bank sell rate of 17.80 (e.g., BBVA), you would receive 1,780 MXN when buying pesos.
• At the Western Union rate of ~16.40 (including fees), 100 USD yields about 1,640 MXN.
• Using Wise with its mid-market rate near 17.30, 100 USD ≈ 1,730 MXN after the low fee.

The difference between the best and worst option for the same $100 is roughly 140 MXN — enough for a good meal in Mexico City.

The implication: digital transfers generally offer better value for larger amounts.

How to Get the Best Exchange Rate in Mexico

1. Check Banxico’s reference rate as a baseline — use Banco de México’s market portal.
2. Compare bank buy rates online for Banamex, BBVA, and Santander before going to a branch.
3. Use a digital service like Wise for transfers — it typically beats bank spreads by 1–2%.
4. Avoid exchanging at airports or hotels where spreads are widest.
5. Ask about commissions — some exchange houses add hidden fees.

Comparing these steps helps you keep more of your money.

What’s Clear and What’s Not

Confirmed facts

• Banxico publishes daily official rates every business day (Banco de México).
• Major banks offer live rates online and update them during business hours.
• 1 USD = 17.36 MXN was the interbank reference in October 2023 (Banxico SIE).

What’s unclear

• Actual cash rate at a specific branch may be different from the published online rate.
• Dólar blue rates in Mexico are unofficial, unregulated, and vary widely by vendor.
• The phrasing “a cuánto está el dólar” can refer to either the official interbank rate or the retail bank rate, causing confusion (Banco de México – market portal).

These uncertainties matter when planning a trip or transfer.
