The Peso's Two-Week Slide: USD/MXN Climbs Toward 18.40 (Sept-Oct 2026)
Between September 22 and October 1, 2026, the dollar rose against the Mexican peso in nine of ten sessions, taking USD/MXN from 17.21 to 18.30. Relive the final, steepest stretch of the climb hour by hour.
For much of 2026 the Mexican peso was one of the steadier emerging-market currencies, and in mid-September Binance's USDT/MXN market — which tracks the dollar-peso exchange rate against a dollar stablecoin — was trading around 17.2. Then the dollar began to climb, and it barely paused for two weeks.
The replay picks up on Sunday, September 27, with the pair near 17.75 after a first leg higher. Monday brought another step: USD/MXN rose steadily through the European and US sessions and closed at 17.98. On September 29 it crossed 18 for the first time since early April, peaking near 18.13 in the afternoon. September 30 was a consolidation day, with dips toward 17.94 bought quickly.
October 1 delivered the high. The pair climbed through the European morning to around 18.24, paused, and then pushed to 18.38 in the 15:00 UTC hour. It closed the day at 18.30, the peso's weakest close since December 3, 2025 and above the 18.10 at which the pair ended 2025. On October 2 the dollar eased back to 18.18 as the move finally cooled.
Note the brief spikes down toward 17.90 in the 19:00 and 20:00 UTC hours on October 1. They reversed immediately and are a reminder that this is a thin market compared with the interbank one, where wicks in quiet hours can exaggerate what the wider market did. The useful signal is the staircase itself: a sequence of higher closes, each consolidation holding above the last, which is how a sustained currency trend usually looks from the inside.
