The Mexican peso fell more than 1% against the US dollar on Monday, September 14, 2026, according to El Economista. The currency weakened to 17.15 per dollar, a level reported by La Jornada.
Two forces drove the move, El Economista reported. Rising tensions in the Middle East pushed investors toward safe-haven assets, and markets were positioning ahead of the Federal Reserve's expected rate decision later in the week. La Jornada noted that investors showed a preference for refuge assets over emerging-market currencies like the peso.
The peso's decline came at the start of a week in which the Fed's policy meeting was the central focus for currency markets. El Economista framed the combination of geopolitical risk and US rate expectations as the main drivers of the currency's slide.

Additional outlets, including Yahoo Finanzas, MILENIO, and El Informador, also reported the peso's retreat against the dollar on the same day, underscoring the broad market attention the move received.
What to watch next: the Federal Reserve's rate decision and any further developments in the Middle East, both of which could continue to shape the peso's direction this week.
