The peso ceded a little ground in Wednesday trading, with USD/MXN near 18.64 by the Mexico City close. Real-time feeds showed the pair moving in a day’s range between roughly 18.5110 and 18.6651, a tight band that kept recent gains intact but tilted the tape modestly in favor of the dollar.
The dollar’s broader tone was soft. The ICE U.S. Dollar Index hovered around 97.8, down about 0.3% on the day, which normally lends a hand to the peso but didn’t fully translate this session as traders squared positions ahead of U.S. data.

On the official side, Banxico’s FIX and DOF references for August 13 confirm a steady backdrop: the FIX series for the date and the DOF-published rate of 18.5657 anchor institutional pricing, while the “para pagos” reference—used to settle certain dollar-denominated obligations—printed 18.6683 around these dates. Those markers help explain why spot hovered close to mid-18s even as intraday flows moved the tape.
The global story is the U.S. rate path. Odds for a September Federal Reserve cut are now over 90% for a 25-basis-point move, with single-digit odds for 50 bps, according to market pricing tracked by CME’s FedWatch and reported by market desks.
What’s moving the bets
The recalibration followed cooler July U.S. inflation and softer labor readings, trends that have pulled the market toward at least a small cut. That dovish tilt got a louder political voice today when Treasury Secretary Scott Bessent said a 50-basis-point cut should be on the table in September and that policy rates may need to fall as much as 150–175 bps over time. Markets heard him—but still price the larger move as unlikely for now.
For Mexico, the external rate path meets a domestic easing cycle. Banxico reduced its policy rate to 7.75% on August 7, slowing the pace to a quarter-point after a series of larger moves. The board emphasized caution, balancing a cooling headline CPI with sticky core pressures. That stance keeps carry supportive for the peso, but narrows the cushion as the Fed inches toward easing.
The near-term setup
Tomorrow brings two data points that could shake the tree: July Producer Price Index at 8:30 a.m. ET and weekly jobless claims minutes later, both are habitually market-moving into FOMC meetings. A softer-than-expected PPI or a jump in claims would bolster cut odds and could cap dollar strength, while upside surprises may nudge USD/MXN higher into the weekend.
Short term, the peso’s technicals look fine: the week’s 18.51–18.66 range has contained price action, and the broader dollar drift remains lower. But positioning is sensitive to the September 16–17 FOMC. Any hint from officials that the larger cut is in play would likely steepen moves in high-beta FX, Mexico included.
