USD to MXN in August 2026: high, low, average
Updated September 26, 2026
The US dollar bought 17.064 Mexican pesos on average in August 2026. The month started at its high, 17.321 on August 3, and the peso strengthened from there: the low of 16.898 came on August 21, and the month closed at 17.008. From first to last fixing, the dollar lost 1.8% against the peso. The figures are cross rates from 21 European Central Bank reference fixings.
Fourteen down days
The dollar fell on 14 fixings and rose on 7. The largest single move was a fall of 0.56% on August 7, to 17.155. The range between the monthly high and low was 2.5%.
For anyone sending money to Mexico, this was a month where waiting cost pesos: each dollar converted into fewer pesos as August went on.

Remittances: what the numbers mean for families
Remittances from the United States are among the most common reasons people check this rate. For a family receiving dollars, a lower USD/MXN rate means fewer pesos for the same transfer. In August 2026 the best reference day was August 3, and the least favourable was August 21.
Over a year the effect is larger than over a month: the same dollar transfer brought noticeably fewer pesos in August 2026 than in August 2025. Senders who set a fixed dollar amount might check whether it still covers the same expenses in pesos.
For businesses
Mexican exporters paid in dollars received fewer pesos per dollar as the month went on. US companies paying Mexican suppliers in pesos paid more dollars. At the monthly average one peso was worth 0.058607 dollars.
Transfer services differ widely in the rate they apply. Checking the reference rate of the day before sending shows how much of the difference between the market and your quote is a fee.
Timing a transfer
Daily moves in the peso are often small, but they add up: in August the rate slipped on two days out of three. If you send money every month on a fixed date, you cannot pick the day, so compare providers instead. If you send occasionally, check the rate over several days and avoid converting right after a large move you do not understand.
What to do
- Look up the rate of your transfer date on the USD/MXN daily rates for August 2026 page.
- Open USD/MXN on the high day of the month to see the August 3 fixing.
- Compare the peso amount your family received with the reference rate of that day.
- See USD/MXN in 2026 for the trend of the year.
