Entering the middle of the week, it is time to see how the U.S. currency has moved in Mexico. For this Wednesday, August 26, the price of the dollar in Mexico is 16.9278 Mexican pesos, a figure that has increased slightly following the drop to 16.90 over the previous weekend. It is also important to note that the FIX exchange rate will be released around midday.
This means that if you exchange dollars at a bank counter or currency exchange office, you will see buying and selling prices slightly above or below that level, depending on the institution. The market has remained relatively stable in recent weeks, moving within a range of around 16.90 to 17.30 pesos per dollar, with small daily variations.
FIX Exchange Rate in Mexico — Wednesday, August 26, 2026
The FIX exchange rate for settling obligations in U.S. dollars on Wednesday, August 26, according to Banxico, is 16.9660 pesos per U.S. dollar.
This exchange rate is determined by Banxico on banking business days based on the average of wholesale foreign exchange market quotations and is announced at midday on the previous day.
| Bank | Buying Price | Selling Price |
|---|---|---|
| Afirme | 16.00 | 17.60 |
| Banco Azteca | 16.50 | 17.74 |
| Bank of America | 16.0256 | 17.9211 |
| Banorte | 15.80 | 17.30 |
| Grupo Financiero Multiva | 17.00 | 17.00 |
| BX+ | 16.4461 | 17.4611 |
One point to keep in mind is that the FIX exchange rate is a crucial tool for Mexico’s financial market because it determines the official value of the peso against the U.S. dollar. This value is calculated by the Banco de México (Banxico), based on a weighted average of wholesale transaction quotations. This process ensures that the exchange rate is representative of actual market transactions, providing transparency and stability for companies and individuals conducting foreign-exchange operations.
The FIX rate is determined every banking business day starting at 12:00 p.m. and is officially published in the Official Gazette of the Federation (DOF) the following day. This figure is important because it is used to settle obligations and contracts denominated in dollars that are paid in Mexico. Through this mechanism, both companies and individuals can plan and conduct international transactions using a clear and regulated reference.
Banxico’s FIX Rate and Bank Prices: Which Reference Should You Use?
The FIX exchange rate is the official reference that Banxico calculates every banking business day based on a weighted average of wholesale transactions in the foreign-exchange market. This value is subsequently published in the Official Gazette of the Federation (DOF) and is used for contracts, international payments, invoicing, and other formal transactions, making it the most reliable starting point for measuring the strength of the peso against the dollar.
However, the price you see when visiting a bank is not exactly the FIX rate, but rather the market price (spot or over-the-counter rate), which incorporates commissions, operating costs, and each institution’s profit margin. Therefore, it is normal to find differences of several cents between banks and currency exchange offices, even at the same time of day.
A practical way to use the FIX rate is to treat it as a “baseline”: if the retail selling price is significantly above that value, it is worth comparing other options before completing your exchange.
Difference Between the Official Exchange Rate and the Retail Bank Rate
To make better decisions, it is important to understand the difference between the official exchange rate (FIX) and the price applied to the public:
- The FIX is a reference rate calculated using a weighted average of wholesale transactions during certain morning hours.
- It does not change in real time: once determined for the day, it remains fixed and is used to settle dollar-denominated obligations within Mexico’s financial system.
- The market price, on the other hand, moves throughout the day according to supply and demand, economic news, central-bank decisions, and international capital flows.
At a bank counter, you will always see two prices: buying (what the bank pays you for your dollars) and selling (what the bank charges you if you want to buy dollars). The difference between the two is known as the spread and is part of the institution’s profit.

Frequently Asked Questions (FAQ) About the Exchange Rate in Mexico
What factors determine the exchange rate between the U.S. dollar and the Mexican peso?
The exchange rate between the U.S. dollar and the Mexican peso is determined primarily by the law of supply and demand in financial markets.
Macroeconomic factors such as central-bank interest rates (the Federal Reserve and Banco de México), inflation, economic growth, political stability, and foreign investment flows directly influence demand for one currency relative to the other, causing its value to adjust continuously.
How does the price of oil affect the value of the Mexican peso?
The Mexican peso is considered a commodity-linked currency. Since Mexico is an important producer and exporter of oil, when international crude prices rise, the country is expected to receive more foreign currency, which tends to strengthen the peso against the dollar. Conversely, a decline in oil prices generally tends to weaken the national currency.
What role do remittances play in the peso’s stability?
Remittances represent a significant inflow of foreign currency into Mexico, primarily from the United States. By increasing the supply of dollars in the domestic economy, these flows help support the value of the peso and provide a financial cushion that helps stabilize the currency during periods of external volatility.
