Overview of the Mexican Peso’s Recent Movement

The Mexican peso experienced a slight decline against the US dollar on Tuesday morning, despite an initial advance. This shift occurred following the release of Mexico’s inflation data, which supports expectations of further interest rate adjustments by the Bank of Mexico (Banxico).

Spot Exchange Rate and Dollar Movement

The spot exchange rate currently stands at 18.6139 pesos per dollar, marking a decrease of 4.48 centavos or 0.24% compared to the previous day’s closing rate of 18.6587 pesos, as per Banxico’s official data.

The dollar’s value fluctuates between a high of 18.7386 pesos and a low of 18.6220 pesos. Meanwhile, the Intercontinental Exchange’s Dollar Index (DXY), which measures the dollar against a basket of six reference currencies, increased by 0.09% to 97.54 points.

Local Inflation Data

Mexico’s consumer price index (CPI) rose by 0.06% in August, aligning with market expectations. On an annual basis, the CPI increased by 3.57%, slightly above June’s rate but still within the official target range of 3% ±1 percentage point.

Regarding underlying prices, the monthly inflation rate was 0.22%, surpassing expectations. Annually, the underlying inflation rate remained at 4.23%, confirming ongoing challenges in price deceleration.

“A controlled inflation environment preserves purchasing power and offers stability, but the subtle signal of pressures on underlying inflation may suggest caution,” stated Felipe Mendoza, Financial Markets Analyst at digital broker ATFX.

During the previous meeting, Banxico reduced the magnitude of rate adjustments by a quarter percentage point. According to the meeting’s minute, the governing board may consider further reductions in the future.

Peso and National Budget

The peso had briefly appreciated earlier in the morning, as markets also absorbed the presentation of Mexico City’s President Claudia Sheinbaum’s national budget proposal for the upcoming year, unveiled late Monday.
