Peso Mexicano Hoy: Dólar Subió a 17.92 por Tensiones en Medio Oriente (14 Marzo 2026)

The Mexican peso is experiencing volatility on Saturday, March 14, 2026, influenced by rising oil prices and geopolitical tensions. Following an increase in Brent crude prices – surpassing $100 USD due to U.S. Tensions in the Middle East – the official FIX exchange rate reached 17.9218 pesos per dollar, according to data from Banxico.

While trading began at 17.84 pesos, the day closed with upward pressure, pushing the currency to 17.95 pesos in international markets. This fluctuation is a response to global energy uncertainty, directly impacting Mexican banks, where the selling rate is approaching 18.50 pesos.

Why Has the Dollar Price Risen in Mexico?

The dollar has seen a significant increase in value against the peso in Mexico at the start of March 2026. This isn’t an isolated incident and the trend appears likely to continue. The situation stems from a decline in the value of the Mexican peso due to the conflict involving the United States and the Middle East, which has impacted oil prices and, the peso’s value.

This price, nearing 18 pesos per dollar, is a level not seen since September 2025. October marked the beginning of a period where the dollar’s price in Mexico decreased and the Mexican currency strengthened. The current situation underscores the peso’s sensitivity to global geopolitical events.

The ongoing conflict has disrupted oil trade in the Persian Gulf, as approximately 20% of the world’s oil traffic passes through the Strait of Hormuz. Investors are seeking the relative safety of the dollar over local currencies.

Exchange Rate in Mexico — March 13, 2026

Official Rate

• FIX Exchange Rate (Banxico/DOF): $17.8368 MXN per U.S. Dollar.

These rates may vary slightly throughout the day due to internal adjustments and bank schedules. The ranges reflect minor differences due to banking policies and operating hours.

The Banxico FIX exchange rate is a crucial tool for the Mexican financial market, determining the official value of the peso against the U.S. Dollar. This value is calculated by Banco de México (Banxico), based on a weighted average of wholesale market quotes. This process ensures the exchange rate is representative of actual market transactions, guaranteeing transparency and stability for companies and individuals operating with foreign currencies.

The FIX is determined each banking business day starting at 12:00 hours and is officially published in the Diario Oficial de la Federación (DOF) the following day. This data is vital as it is used to settle obligations and contracts denominated in U.S. Dollars that are to be liquidated in Mexico.

What is the Difference Between the Bank of Mexico Exchange Rate and the Market Price?

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

Banxico (FIX) Exchange Rate:

• It is a reference rate determined and published daily by the Bank of Mexico, 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 transactions that reflect prevailing market conditions.
• The FIX is used to settle obligations in foreign currency, banking operations, contracts, and settlements, and is the official reference in invoicing and institutional operations.
• It remains fixed until the next business day, so it is not updated in real time and is generally more stable.

Market Price (spot exchange rate, banking rate, at the window):

• It is the value at which dollars are actually bought and sold at banks, exchange houses, or financial platforms, and 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 slightly higher for the public due to including commissions, profit margins, operating costs, and risk, which is why it is higher at the window than the FIX, and each bank offers different buying and selling prices.

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

How Does Inflation in the U.S. Affect the Peso Exchange Rate Today?

U.S. Inflation directly influences the trend of the Mexican peso today, Sunday, March 8, 2026, modifying market expectations about the Federal Reserve’s (Fed) monetary policy and the behavior of the dollar:

• U.S. Inflation directly affects the exchange rate of the Mexican peso, especially on days like today. If U.S. Inflation is lower than expected, as occurred today, it generates the expectation that the Federal Reserve (Fed) may cut interest rates or not raise them soon. This weakens the dollar against other currencies and generally strengthens the Mexican peso.
• low inflation in the U.S. Today boosts the strength of the Mexican peso, as it reduces global demand for dollars and puts pressure on U.S. 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.
