Dollar to Mexican Peso Today: USD/MXN Exchange Rate – Nov 27, 2025

The Mexican peso continued to demonstrate strength against the U.S. dollar this weekend, trading at 18.30 pesos per dollar on Saturday, November 29, 2025. This represents no movement in the currency pair, and analysts anticipate little fluctuation in the near term, with the peso remaining at a relatively low level compared to recent highs.

Mexico’s central bank, Banco de México, determines the official exchange rate by calculating an average of wholesale quotes from various exchange transaction platforms and significant electronic media, for transactions settling on the second business day. This methodology aims to provide a transparent and representative benchmark for currency valuation.

Over the past two years, the peso has maintained a relatively solid position against the dollar, a trend that was briefly interrupted by the election of Claudia Sheinbaum as president. Her victory initially caused the peso to fall, pushing its value above 20 pesos per dollar. However, the currency has since rebounded firmly, returning to levels below 19 pesos. This resilience underscores the peso’s underlying strength despite political shifts.

Why Has the Dollar Price Fallen in Mexico?

The U.S. dollar experienced a significant decline in Mexico on Wednesday, October 15, according to financial analysis firm Monex. This drop is attributed to political and economic uncertainty in the United States, particularly tensions between the administration of Donald Trump and China, and the resulting increase in tariffs. The situation highlights how geopolitical factors can quickly influence currency valuations.

The dollar has risen 0.65% over the past week, but remains down 6.84% for the year to date, a considerable decrease. The Mexican peso has appreciated 0.19% in recent days, continuing its positive trend against the dollar.

The dollar opened at 18.45 pesos per dollar on Wednesday, October 22, 2025, and may experience slight increases by the close of trading. These fluctuations are typical in the foreign exchange market.

Exchange Rate in Mexico — November 25, 2025

Official Rate

• FIX Exchange Rate (Banxico/DOF): $18.4308 MXN per U.S. dollar.
• Spot Market: $18.499700 MXN per dollar in the early hours of the day, with a previous close of $18.3832 MXN. Another recorded average was between $18.0191 – 18.6904 MXN.

As a result, the dollar is being purchased for approximately $18.0191 MXN and sold for around $18.6904 MXN, depending on the financial institution. These values may vary slightly throughout the day due to internal adjustments and bank schedules.

The Banxico FIX rate is a crucial tool for the Mexican financial market, as it determines the official value of the peso against the U.S. dollar. Banco de México calculates this rate based on a weighted average of wholesale quotes, ensuring transparency and stability for companies and individuals operating with foreign exchange.

The FIX is calculated 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.

What Economic Data from the U.S. Influenced the Peso’s Trend Today?

U.S. economic data influencing the peso’s trend on Wednesday, November 26, 2025, primarily centered on the consumer price index (CPI) figures for the month of August:

• The CPI rose 0.2% month-over-month and 2.7% year-over-year, matching the previous month’s reading and falling below analysts’ expectations (a consensus of 2.8% annually). Core inflation, excluding food and energy, advanced 0.3% monthly and 3.1% annually, showing a rebound in services and housing.
• This data reinforced expectations of a potential interest rate cut by the Federal Reserve (Fed) in September. Traders bet that the Fed would take action given the moderate inflation, weakening the dollar and favoring the Mexican peso during the session.
• Attention was also paid to the extension of U.S. tariffs on China and a busy agenda of other indicators that could influence future Fed decisions, such as wholesale inflation, retail sales, and consumer confidence, although that data had not yet been released today.
• The start of September was also marked by low trading volume due to the Labor Day holiday in the U.S., which amplified exchange rate movements in Mexico.
• Markets also monitored pending economic reports in the U.S., including retail sales and employment figures, as well as the uncertainty generated by trade and political disputes.

In summary, the peso’s appreciation was primarily due to U.S. inflation coming in lower than anticipated, favoring expectations of a less restrictive monetary policy by the Fed and weakening the dollar in international markets today.

What Was the Dollar’s Closing Price in Mexico on November 25?

The dollar closed at 18.3547 pesos in Mexico on Monday, November 24, 2025, according to average data from banks and interbank records announced by Banco de México (Banxico) and specialized media. This value represents the weighted average with which transactions were settled at the end of the trading day.

The official FIX exchange rate for settling dollar-denominated obligations, published in the Diario Oficial de la Federación (DOF), was 18.4308 pesos per dollar for the same day.

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 Exchange Rate (FIX):

• 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 foreign 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, bank rate, window rate):

• It is the value at which dollars are actually bought and sold in 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.

Therefore, 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’s Quotation Today?

U.S. inflation directly influences the trend of the Mexican peso today, Wednesday, November 26, 2025, by modifying market expectations about the Federal Reserve’s (Fed) monetary policy and the dollar’s behavior:

• U.S. inflation affects the peso’s quotation, 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.
• Thus, low inflation in the U.S. today drives 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 session.
