Mexican Peso Hits Worst Weekly Decline Against US Dollar in Nearly Seven Months
The Mexican peso has experienced its worst weekly drop against the US dollar in nearly seven months. On Sunday, September 27, 2026, the dollar exchange rate stands at 17.68 pesos per dollar, according to data from Investing.com.
This depreciation of 2.65% against the dollar reflects the erosion of the carry trade appeal that had supported the peso for most of the year, experts say. The Monex financial group notes that the Mexican currency is under pressure following Banxico's decision to hold its benchmark interest rate at 6.50%, amid persistent expectations of a more restrictive Federal Reserve (the Fed) and a narrower rate differential.
The dollar exchange rate today, September 27, 2026, is expected to trade between 17.63 and 17.75 pesos per dollar, driven by the dollar's relative strength and caution around the rate differential. For payment of obligations, the buying price stands at 17.503 pesos, while for selling, it's 17.6425 pesos.
