Mexico’s peso is experiencing an unexpected surge in value, currently trading near a key 18 pesos per U.S. dollar threshold. This rebound follows a volatile period sparked by political shifts and economic uncertainty following the June 2024 elections and the U.S. presidential election. Despite fears of negative impacts from potential tariffs and policy changes, the peso has not only recovered but has become one of the best-performing emerging market currencies of the year, trailing only the Russian ruble, Hungarian forint, Czech koruna and Colombian peso in gains against the dollar. This report examines the factors driving this resilience and the challenges that may lie ahead for sustaining this positive trend.

The Mexican peso is nearing a key threshold, trading close to 18 pesos per U.S. dollar, following a sustained period of positive performance that has strengthened the currency.

Despite a challenging start to the year, when the peso fell from 16 to almost 21 pesos per dollar following the June 2024 elections and the subsequent reforms to the judiciary and autonomous organizations, coupled with Donald Trump’s victory in the November presidential election, the currency has rebounded significantly. Throughout the year, marked by tariff concerns and trade pressures, the peso appreciated by 15.6 percent.

This appreciation was surpassed only by the Russian ruble, which rose 42.1 percent, as well as the Hungarian forint, the Czech koruna, and the Colombian peso, which gained 21.1, 17.7, and 15.9 percent against the dollar, respectively.

The second half of the year has been particularly favorable for the peso, with a 7.9 percent appreciation in its exchange rate, trailing only Colombia and Hungary. This positive trend reflects Mexico’s resilience in the face of global economic headwinds.

Economists point to a combination of internal and external factors driving the peso’s unexpected strength, pushing it from a low of 21 pesos per dollar towards potentially breaking the 18-peso barrier.

Peso Defies Expectations Amid Trump Tariffs and Political Shifts

Despite the changes to Mexico’s autonomous organizations, the judicial reforms, and Donald Trump’s presidency, the peso has outperformed expectations, reversing the depreciation seen following these developments. This resilience is attributed to a series of favorable internal and external factors.


According to the Bank of Mexico’s (Banxico) Financial Stability Report, a primary driver of the peso’s appreciation is Mexico’s relatively successful navigation of trade tensions with the United States, particularly concerning tariffs and unilateral sanctions imposed by the Trump administration.

Banxico also highlighted the weakness of the U.S. dollar as a contributing factor to the peso’s gains.

Furthermore, the decline in U.S. interest rates, combined with low peso volatility, has boosted the “carry trade,” a strategy where investors borrow in currencies with low interest rates and invest in those with higher rates – and a key contributor to the peso’s recent appreciation. Mexico remains an attractive destination for carry trade activity, even with recent interest rate cuts.

With just over two weeks remaining in the year, the peso may even surprise the Ministry of Finance, which had projected an exchange rate of 18.7 pesos per dollar in its Economic Package. Beyond the carry trade and the year’s trade negotiations with the U.S., other factors contributing to the peso’s “renaissance” include:

  • A balance in external accounts.
  • Strong export performance, reaching $66.1 billion per month.
  • Foreign direct investment (FDI) exceeding expectations, totaling $40.9 billion at the end of the third quarter.
  • Remittance inflows, reaching $62 billion between October of the previous year and October of this year.

While stable economic fundamentals support the peso, sustaining levels below 18 pesos per dollar may prove challenging, as the interest rate differential between Mexico and the United States is “shrinking,” potentially curbing carry trade activity.

Adding to the uncertainty is the renegotiation of the USMCA trade agreement and its potential impact on the peso.
