The weekend is approaching and, in recent days, one of the most searched topics has been the price of the dollar in Mexico. For this Saturday, March 7, 2026, the exchange rate is located at 17.80 pesos per dollara figure significantly higher than that recorded in recent months and which reflects a notable increase in recent days. Below, I share more details about it.

Why has the Price of the Dollar increased in Mexico?

For this beginning of the month of March 2026, the dollar has had a fairly significant rise in Mexico. No, it is not your imagination nor is it an isolated event, since it seems that the situation still has a long time to go. This is a drop in the value of the Mexican peso due to the conflict between the United States and the Middle East, which has affected oil prices and that modifies the value of the Mexican peso, leaving it on the floor in recent days..

This price, which is almost 18 Mexican pesos for each dollar that is exchanged, is something that has not been seen since September 2025, October being the month in which the price of the dollar began to fall in Mexico and the Mexican currency became a little stronger.

Let us remember that the war has paralyzed the oil trade in the Persian Gulf, because almost 20% of the world’s oil traffic passes through the Strait of Hormuz and investors prefer to take refuge in the dollar rather than in any local currency.

Exchange Rate in Mexico — March 7, 2026

Official quote

• FIX exchange rate (Banxico/DOF): $17.6770 MXN per US dollar.

These values ​​may vary slightly throughout the day due to internal adjustments and schedules of each institution. The ranges reflect slight differences due to hours and internal bank policies.

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.

What is the difference between the Bank of Mexico exchange rate and the market price?

The main difference between the exchange rate of the Bank of Mexico (Banxico) and the market price is the way they are calculated and used:

Banxico (FIX) exchange rate:

• It is a reference rate that the Bank of Mexico determines and publishes daily, usually around noon.
• It is calculated from a weighted average of quotes collected from the wholesale exchange market during three specific periods in the morning, considering operations that reflect prevailing market conditions.
• The FIX is used to settle payment obligations in foreign currency, banking operations, contracts and settlements, and is the official reference in billing and institutional operations.
• It remains fixed until the next business dayso it is not updated in real time, and is usually more stable.

Market price (spot, bank, over-the-counter exchange rate):

• It is the value at which dollars are actually bought and sold in banks, exchange houses or financial platformsand may differ between institutions.
• This price varies constantly during the day according to supply and demand, economic expectations, monetary policy, news, and international factors.
• It is usually a little higher for the public because it includes commissions, profit margin, operating costs and risk, which is why at the counter it is higher than the FIX, and each bank offers different purchase and sale prices.

Therefore, when you consult a bank price, there is usually a difference of cents (sometimes greater) compared to the FIX value. The FIX helps provide order and transparency to the Mexican market, but it does not determine the final price of each individual operation.

How does inflation in the US affect the price of the Mexican peso today?

US inflation directly influences the trend of the Mexican peso today, Tuesday, February 3, 2026modifying market expectations about the monetary policy of the Federal Reserve (Fed) and the behavior of the dollar:

• Inflation in the US directly affects the price of the Mexican peso, especially on days like today. If the US inflation turns out to be lower than expectedas happened today, generates the expectation that the Federal Reserve (Fed) could cut interest rates or not upload them soon. This weakens the dollar against other currencies and generally strengthens the Mexican peso.
• Thus, the Low inflation in the US today drives the strength of the Mexican pesoas it reduces global demand for dollars and adds pressure on US authorities to avoid tightening their monetary policy. This causes the dollar exchange rate to have a downward trend against the Mexican peso during the day.
