Expert Analysis

Felipe Mendoza, an analyst at ATFX Latam, stated: “The market continues to favor Mexico due to its interest rate differential and proximity to the US market, although bilateral political factors and the global dollar’s evolution will continue to shape the peso’s exchange rate.”

Monex Grupo Financiero added: “Looking ahead to overnight, we predict a range of 18.39 to 18.46 pesos per dollar, considering the dollar’s retreat but the yen’s strength, which is correlated with carry trade strategies involving pesos, pending the Fed’s policy announcement.”
