Peso ends the week at 18.16 per dollar, its worst since March

The Mexican peso ended Friday, Oct. 2, 2026, at 18.1637 per dollar, according to Banco de México figures that La Razón reproduces. The currency, which Mexico's central bank tracks daily, gained about 0.7 % on the day and broke four straight sessions of losses. Markets do not reopen until Monday, Oct. 5.

Even so, between Sept. 28 and Oct. 2 the peso had its worst week since March 2026. It had closed at 17.7072 per dollar on Friday, Sept. 25, so the gap is 45.65 centavos, around 2.6 %, using the closes published by La Razón. Other measures put it as high as 2.74 %, because the source and the cutoff time differ.

The Friday rebound coincided with the U.S. jobs report: 29 000 nonfarm jobs in September and 4.2 % unemployment, according to the Bureau of Labor Statistics. Grupo Financiero Monex had expected 89 000, as this outlet reported the same Friday.

According to Investing.com México, the weak figure reduced expectations that the Federal Reserve would raise rates again in October. A day earlier, on Thursday, the currency reached 18.43 per dollar, its weakest level of 2026 so far, per the same source.

Kapital Grupo Financiero, cited by Investing.com, argues that the structural risk for the currency is a narrowing gap between Mexican and U.S. interest rates. Banxico's benchmark rate has stood at 6.50 % since its Sept. 24 decision.

Next on the calendar is the minutes of that decision, which by Banxico's usual schedule would come out Oct. 8, and the September inflation index from INEGI, Mexico's statistics institute, which it has scheduled for the same day.
