# Mexican Peso plunges as US-Mexico interest rate differential reduces

> The Mexican peso fell about 1.8% to 17.99 per dollar on October 1 as stalled US-Iran talks weakened sentiment. Rising US Treasury yields strengthened the dollar, with the Dollar Index near 101.17. Banxico Governor Victoria Rodriguez said the depreciation stays within existing inflation forecasts.

## Why it matters

Geopolitical uncertainty and higher US yields are pushing the peso lower, raising the peso cost of imported feed for Mexican buyers. Energy-linked risk premium may also affect broader commodity sentiment.
