Overview of the Mexican Peso’s Performance

The Mexican peso experienced a slight depreciation against the US dollar on Tuesday, as the greenback gained ground in a market that absorbed news of an agreement between the United States and Australia to bolster their independent supply chain for rare earths. The peso fell by 2.86 centavos, or 0.16%, to close at 18.4397 units per dollar, according to official data from Banco de México (Banxico).

Dollar’s Uptick

Experts from Monex Grupo Financiero highlighted that the dollar’s rise against its major counterparts was fueled by the news of a US-Australia agreement to strengthen their independent rare earths supply chain, free from Chinese influence. The market participants are now anticipating the release of US inflation figures for September by week’s end, as the government shutdown has suspended the dissemination of official indicators.

Geopolitical Factors and Local Indicators

Investors are keeping a close eye on the upcoming trade talks between Chinese and US officials, as well as any updates regarding the potential end to the ongoing US government shutdown. Meanwhile, Mexico’s economic activity contracted by 0.6% in September compared to the same month last year, according to preliminary INEGI data. When contrasted with August’s figures, the economy would have expanded by 0.1%.

Impact on the Mexican Economy

Felipe Mendoza, an analyst at ATFX, stated that the exchange rate remains within a technical range of 18.30 to 18.60 pesos per dollar, with a moderate depreciation bias in the short term due to lingering uncertainty surrounding local economic fundamentals.
