Mexican Peso Holds Steady After Banxico Rate Cut

In a late 2025 marked by peso-dollar volatility and monetary decisions, the Mexican currency concluded the week with marginal gains. This occurred immediately after the Bank of Mexico (Banxico) determined a reduction of 25 basis points in its benchmark interest rate. However, this optimism contrasts with warnings of structural risks and trade tensions led by President Donald Trump.

The Peso’s Paradox: Closing Figures After Banxico’s Decision

The Mexican peso, despite the decrease in interest rates, managed to maintain a marginal appreciation against the US dollar, closing on Friday, December 19, with different figures according to financial institutions. According to data from Banxico, the Mexican currency appreciated by 0.02 percent or 0.38 cents compared to its previous close.

The closing figures reported on December 19, 2025, were:

• Banxico close: The exchange rate stood at 17.99 pesos per dollar.
• Dow Jones close: The average quote was 18.01 Mexican pesos, implying a change of 0.04% compared to the previous day’s figure (18 pesos).
• Bank teller windows: According to data published by Banamex, the dollar sold for 18.47 pesos each.

In the weekly balance, the peso gained 0.07 percent or 1.32 cents. Additionally, the US dollar has accumulated a decrease of 0.02% in the last seven days and, in the last year, still maintains a decrease of 11.96%.

Context of Volatility and Forecasts

The analysis of the day showed that the volatility figure presented behavior clearly lower than that reflected in the data from the last year, showing fewer variations than usual at this time.

Gabriela Siller, director of economic analysis at Banco Base, detailed that, although the exchange rate trades near 18.00 pesos per dollar and downward pressures persist, the peso could enter a period of upward correction.

In the money market, the yield on the 10-year bond for the United States is 4.14 percent, while the 10-year bond in Mexico remains at a level of 8.91 percent.

In contrast to Mexico’s marginal appreciation, several emerging currencies depreciated:

• Russian ruble (0.42%).
• Philippine peso (0.30%).
• South Korean won (0.25%).
• Brazilian real (0.19%).
• Indonesian rupiah (0.17%).
• Turkish lira (0.14%).

At the same time, the dollar index (DXY), which measures the strength of the North American currency, reported an advance of 0.18 percent, at 98.60 whole units. The Bloomberg dollar index (BBDXY) added 0.15 percent at 1,209.32 units.

Mexico in the Global Storm: Solid Position Despite Uncertainty

Grupo Bursátil Mexicano (GBM) Casa de Bolsa warns that, although risks persist, Mexico is in a relatively solid position compared to other emerging economies.

The analysis highlights that the perception of a more moderate and pragmatic economic management has favored the narrative about the country, making it one of the preferred destinations in Latin America for international funds.

The Shadow of Donald Trump’s Tariffs and the USMCA

The reconfiguration of global trade, marked by tensions, has forced Mexico to prioritize a close relationship with the United States. However, the trade decisions of President Donald Trump have generated concern.

The recent warning to impose 30% tariffs on Mexican and European products—not counting sectoral tariffs, such as 25% on the automotive sector—has revived speculation among investors about a possible increase in tariffs applied to Mexican exports to the US market.

Given this outlook, the upcoming review of the USMCA acquires strategic relevance, as:

• The renegotiation could open new opportunities against Asian competitors.
• If it manages to provide certainty for investments linked to nearshoring, the country would consolidate its position as a preferred destination for the relocation of production chains.

Economic Perspectives and Structural Challenges

GBM analysts project limited economic advancement for this year, with an estimate of 0.5%, although they foresee more favorable conditions in the second half. Investment could experience greater dynamism, driven by programs such as the “Plan Mexico” and by the downward trend in interest rates.

Sectors such as consumption, technology (including integration with artificial intelligence), health, and fintech have shown resilience and are emerging as factors that open opportunities for both investors and markets.

Nevertheless, structural risks persist that limit the absorption capacity of the labor market, such as:

• The moderation in the generation of formal employment.
• The increase in underemployment.
• The risk that remittance flows could be affected by changes in US immigration policy.

According to GBM, these elements configure an environment of external volatility and internal institutional adjustments that will mark the close of 2025 for the Mexican economy.

Historical Notes on the Mexican Currency

The Mexican peso is the legal tender of Mexico and is the first currency in the world to use the $ sign, which was later adopted by the United States for the dollar.

This currency is the fifteenth most traded currency in the world, as well as the most traded in Latin America and the third on the continent only behind the US dollar and the Canadian dollar.

The abbreviation MXN is currently used to refer to the Mexican peso, but before 1993 the initials MXP were used. One Mexican peso equals 100 cents. There are coins of 1, 5, 10, and 20 pesos, and bills of 20, 50, 100, 200, 500, and 1,000 pesos.

The strength of the Mexican peso at the close of 2025 seems to rest on shifting sands: while Banxico has given the market a respite and the country maintains an appeal compared to emerging markets, the foundations are being tested by internal labor slowdown and, crucially, by uncertain US tariff policies. Will Mexico be able to capitalize on the nearshoring opportunity and mitigate geopolitical risks, or will the upward correction forecast by analysts mark the beginning of a trend change in 2026?
