Dólar a Peso Mexicano: Precio HOY, 16 de marzo de 2026 y por qué sube

The Mexican peso saw a slight dip against the U.S. Dollar on Monday, March 16, 2026, trading at 17.86 Mexican pesos per dollar. This represents a modest decrease from Friday’s closing value, following weeks of dollar strength influenced by geopolitical tensions in the Middle East. The exchange rate is being closely watched by businesses and investors with exposure to both economies.

Factors Driving the Dollar’s Appreciation in Mexico

The dollar has experienced significant gains against the peso in early March 2026, a trend analysts attribute to the ongoing conflict involving the United States in the Middle East. This situation has impacted global oil prices and, the value of the Mexican peso. The peso’s recent performance reflects investor concerns surrounding regional instability and its potential economic repercussions.

The current exchange rate, nearing 18 pesos per dollar, is a level not seen since September 2025. October marked a turning point, with the peso regaining some strength as the dollar’s value began to decline. The recent shift underscores the sensitivity of the Mexican currency to international events and commodity markets.

Disruptions to oil trade in the Persian Gulf, particularly through the Strait of Ormuz – a critical transit point for approximately 20% of the world’s oil supply – have prompted investors to seek the relative safety of the U.S. Dollar over local currencies.

Exchange Rates in Mexico — March 16, 2026

Official Rate

• Tipo de cambio FIX (Banxico/DOF): $17.8368 MXN per U.S. Dollar.

These rates are subject to slight variations throughout the day due to internal adjustments and bank schedules. The ranges reflect minor differences based on banking policies and operating hours.

The Banxico FIX rate is a crucial tool for the Mexican financial market, establishing the official value of the peso against the U.S. Dollar. Banco de México (Banxico) calculates this value based on a weighted average of wholesale market quotes, ensuring transparency and stability for companies and individuals conducting foreign exchange transactions.

The FIX is determined each 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 for settling dollar-denominated obligations and contracts in Mexico.

Banxico Exchange Rate vs. Market Price: What’s the Difference?

The primary difference between the Banco de México (Banxico) exchange rate and the market price lies in how they are calculated and used:

Banxico Exchange Rate (FIX):

• It is a reference rate determined and published daily by the Bank of Mexico, typically 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 tends to be more stable.

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

• 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 throughout 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, by 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 it was 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 monetary policy. This causes the dollar exchange rate to have a downward trend against the Mexican peso during the day.
