Background on Key Figures and Institutions

The Mexican peso appreciated against the US dollar on Tuesday, reaching its strongest level since mid-2024. This surge was driven by lower-than-expected local inflation, which bolstered expectations that the Bank of Mexico might pause its interest rate cutting cycle. Additionally, a generalized weakening of the US dollar played a role.

Monex Casa de Bolsa analysts predict the peso will trade within a range of 17.90 to 17.99 units overnight, supported by the resilience of the peso and the dollar’s weakness amid a lack of significant economic news during the upcoming trading session.

Mexican Peso’s Performance

At the close of trading, the exchange rate stood at 17.9156 pesos per dollar, marking a gain of 6.60 centavos or 0.37% compared to the previous close, according to data from Banco de México.

This appreciation brought the local currency to its best level since July 22, 2023, when it closed at 17.9408 pesos per dollar.

US Dollar’s Performance

In contrast, the US dollar index, which measures the performance of the US currency against a basket of major currencies, fell 0.34% to 97.94 points—its lowest level in over two months. The dollar weakened despite the US Gross Domestic Product (GDP) showing stronger-than-expected growth in the third quarter.

Initial estimates indicated a 4.3% increase in the GDP, significantly higher than economists’ forecast of 3.3%. This growth was fueled by robust consumer spending.

Local Inflation Data

On the domestic front, Mexico’s National Institute of Statistics and Geography (Inegi) reported that general inflation for the first half of December was 0.17%, falling short of analysts’ expectations of 0.30%. On an annual basis, inflation moderated to 3.72% from the previous 3.99%, remaining within the Bank of Mexico’s variability range.
