Puerto Vallarta, Jalisco, July 18, 2026 – The U.S. dollar ended Friday’s Mexican trading session at 17.5233 pesos, according to Banco de México’s official closing data.
The rate was calculated shortly before 2:10 p.m. Central Time on Friday, July 17. It was up from Thursday’s close of 17.4223 pesos, an increase of about 0.58% in the USD/MXN rate. In practical terms, the peso lost roughly the same percentage against the dollar during the session.
As of 6:30 a.m. On Saturday, July 18, no later regular Mexican market closing time was available. Weekend quotes shown by banks, currency applications and exchange houses may differ from Friday’s interbank benchmark.
Banco de México also set Friday’s official FIX exchange rate at 17.5242 pesos per dollar, compared with 17.4418 on Thursday. The FIX is based on wholesale market quotations and is used for certain financial and legal calculations. It is not the rate most customers receive at a bank, ATM, or exchange counter.
Peso Loses Ground in a Risk-Off Session
The dollar traded between 17.5090 and 17.5370 pesos during Banco de México’s Friday observation period. The movement followed a broader shift toward safer assets as renewed conflict between the United States and Iran disrupted traffic near the Strait of Hormuz and pushed oil prices toward one-month highs.
The escalation coincided with a global stock-market decline led by technology shares. Investors often reduce exposure to emerging-market currencies during periods of geopolitical or financial stress, which can place pressure on the peso even when Mexico-specific news is limited.
The U.S. dollar index was nearly unchanged Friday and finished the week about 0.2% lower, according to global currency-market reporting. That suggests Friday’s peso decline was partly tied to weaker risk appetite rather than to a broad surge in the dollar against every major currency.
Higher oil prices can sometimes help currencies of petroleum-exporting countries. Friday’s trading, however, indicated that concerns over inflation and global supply disruptions outweighed any potential benefit to Mexico’s oil revenue.
Softer U.S. Inflation Limits the Dollar’s Lift
Recent U.S. inflation data continued to pull in the opposite direction.
The U.S. Bureau of Labor Statistics reported that consumer prices fell 0.4% in June after seasonal adjustment. Annual inflation slowed to 3.5%, while prices excluding food and energy were unchanged during the month and 2.6% higher than a year earlier.
Those figures reduced expectations that the Federal Reserve will raise interest rates at its July meeting. Market pricing on Friday placed the probability of an increase at about 14%, down from 25% a week earlier. The Federal Reserve’s next meeting is scheduled for July 28 and 29.
Lower expectations for U.S. rates generally reduce some of the dollar’s yield advantage. On Friday, that pressure was offset by demand for the dollar during the geopolitical and stock-market selloff.
Mexican Inflation, Industry and Trade Talks
Mexico’s annual inflation rate fell to 3.37% in June, down from 3.94% in May, according to INEGI’s consumer-price data. The reading was within Banco de México’s target range of 2% to 4%.
Banco de México held its benchmark interest rate at 6.50% on June 25 after cutting it in May. The relatively high Mexican rate remains a source of support for the peso, although the advantage could narrow if Banxico resumes rate cuts while the Federal Reserve remains on hold.
Recent economic figures have been less supportive. Mexico’s industrial activity declined 0.8% in May from April, reversing part of the previous month’s increase. Weaker domestic activity can limit demand for the peso, although one monthly report is not enough to establish a broader trend.
Trade policy also remains in focus. U.S. officials said negotiations with Mexico over the USMCA review were progressing pragmatically, but unresolved issues include automotive content requirements and rules for electronics, pharmaceuticals, and other strategic goods. A third round of talks is expected in Mexico City during the week beginning July 20.
How Friday’s Move Changes Everyday Conversions
At Friday’s official closing rate, US$1,000 was equal to approximately MXN 17,523 before fees.
The same US$1,000 was worth about MXN 17,422 at Thursday’s close. The one-day difference was approximately 101 pesos.
People receiving income, pensions or transfers in dollars gained modest purchasing power in peso terms. Residents earning pesos faced slightly higher costs when buying dollars, paying in dollar-denominated bills, or budgeting for travel to the United States.
Actual customer rates will be less favorable than the interbank benchmark in most cases. Banks, ATMs, credit card companies, remittance services, and exchange houses add their own spreads, commissions, or withdrawal fees. Puerto Vallarta exchange counters may also post different buying and selling rates depending on location and available cash.
The Calendar Behind the Next Move
Regular Mexican banking activity resumes Monday, July 20. The peso’s opening direction may depend on developments in the Middle East, oil market conditions, and the tone of the upcoming U.S.-Mexico trade meetings.
Mexico’s next scheduled inflation update is due July 23, when INEGI releases figures for the first half of July. U.S. interest-rate expectations will remain active ahead of the Federal Reserve’s July 28-29 meeting.
Anyone making a large conversion should check the provider’s final rate and total fees rather than relying only on the published interbank figure. Weekend quotations can change before Mexican banks reopen Monday.
