Expert Analysis

“The market continues to favor Mexico due to its interest rate differential and close trade ties with the United States, although bilateral political factors and the global dollar’s evolution will continue to shape exchange rate movements,” said Felipe Mendoza, analyst at ATFX Latam.

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