The peso started September with a quiet gain. Mexico’s currency closed Monday at 18.6428 per dollar, a 0.10% improvement from 18.6615 on Sunday’s reference, according to data cited from Banco de México and market reporting. The day’s range ran from 18.6028 to 18.6694. The US Dollar Index eased about 0.10% to 97.67, reflecting a softer greenback.

Mexican peso today
Liquidity was thin with U.S. markets closed for Labor Day, and traders were squarely focused on a heavy labor data slate that could reset Federal Reserve expectations. The JOLTS job-openings report arrives Wednesday, Sept. 3, ADP private payrolls follow Thursday, Sept. 4, and August nonfarm payrolls land Friday, Sept. 5. Those releases shape the Fed’s dual-mandate view and near-term rate path.
A local consultant summed up the tone: support sits around 18.60 and 18.50, and the lack of catalysts made for a calm session given the U.S. holiday. That read aligns with Monday’s narrow trading band.
What’s driving sentiment now
Two U.S. factors framed Monday’s trade. First, Friday’s PCE inflation report held headline year-over-year at 2.6% while core PCE ticked to 2.9%—steady enough to keep hopes alive for a Fed cut, but not weak enough to settle the debate.
Second, markets are digesting a federal appeals court ruling that found most Trump-era tariffs imposed under the International Emergency Economic Powers Act to be unlawful, while delaying their effect to allow for a Supreme Court appeal. That legal backdrop matters for the peso: if tariffs fade, trade frictions ease; if they persist or morph, uncertainty lingers.
On the dollar side, the DXY at ~97.7 underlines a modest headwind for USD across majors—one reason the peso could edge up on a quiet day.
Banxico outlook and what to watch
Fresh private-sector surveys tied to Banxico’s expectations show analysts trimmed their year-end 2025 USD/MXN call to 19.50 (from 19.80) and now see the policy rate at 7.25% (from 7.50%), implying another 50 bps of cuts before December if the data cooperate. Banxico’s Aug. 7 decision already lowered the overnight rate to 7.75%. The evolving rate differential with the Fed will steer carry appeal—and the peso—with each incoming datapoint.
For readers, the takeaway is practical: a stable-to-firm peso near 18.6–18.7 helps importers and travelers in the short run, but the week’s U.S. labor numbers can quickly nudge that range. If payrolls surprise strongly and push Treasury yields up, the dollar typically receives a bid; if they underwhelm, the peso can find more support—especially with Banxico signaling measured easing and inflation trending toward its target.
