Below, I give you more details about this variation in the value of the US currency in Mexican lands.

FIX Exchange Rate in Mexico — Friday, June 5, 2026

The exchange rate to pay the obligations in US dollars was left for this June 5, according to Banxico, in 17.4755 pesos for each green currency.

The FIX exchange rate is determined by Banxico in banking business days from the average of the quotes of the exchange market wholesale and is announced at noon the previous day.

One fact to keep in mind is that the FIX exchange rate is a crucial tool for the financial market in Mexico, as it determines the official value of the peso against the US dollar. This value is calculated by the Bank of Mexico (Banxico)based on a weighted average of wholesale transaction prices. This process ensures that the exchange rate is representative of real market transactions, guaranteeing transparency and stability for companies and individuals that operate with currencies.

The determination of the FIX is carried out every banking business day starting at 12:00 p.m.and is officially published in the Official Gazette of the Federation (DOF) the next day. This information is vital, since it is what is used to settle obligations and contracts denominated in dollars that will be settled in Mexico. Thanks to this mechanism, both companies and individuals can plan and execute international transactions with a clear and regulated reference.

Banxico FIX and prices in banks: what reference to use?

He FIX exchange rate It is the official reference that Banxico calculates every business day based on a weighted average of wholesale operations in the exchange market. This value is subsequently published in the Official Gazette of the Federation (DOF) and is used for contracts, international payments, billing and other formal operations, making it the most reliable starting point for measuring the strength of the peso against the dollar.

However, the price that you see when you go to the bank is not exactly the FIX, but the market price (spot or window), which incorporates commissions, operating costs and the profit margin of each institution. Therefore, it is normal to find differences of a few cents between banks and exchange offices, even at the same time of day.

A practical way to use the FIX is to take it as a “baseline”: if the retail price is well above that value, it is a good idea to compare it with other options before completing your change.

Difference between official exchange rate and window price

To make better decisions, it is key to understand the difference between the official exchange rate (FIX) and the price applied to the public:

• The FIX is a reference rate calculated with a weighted average of wholesale operations during certain morning hours.
• It does not change in real time: once determined for the day, it remains fixed and is used to settle obligations in dollars within the Mexican financial system.
• The market price, on the other hand, moves all day according to supply and demand, economic news, central bank decisions and international capital flow.

At the window you will always see two prices: buys (what the bank pays you for your dollars) and sale (what the bank charges you if you want to buy dollars). The difference between the two is known as “spread” and is part of the institution’s profit.
