Official US dollar exchange rates moved across four Latin American economies on 12 October 2026.

In Venezuela, the official rate exceeded 876 bolívares per dollar, continuing an upward trend that reduces citizen purchasing power [^1]. In Argentina, Banco Nación quoted the official dollar at 1485 pesos for purchase and 1535 pesos for sale [^2]. The Mexican peso gained 0.87% against the dollar measured against the prior Friday close published by Banco de México [^3].

Peru's central bank reported the official dollar closed at 3.4460 soles on 9 October 2026, after opening at 3.4530 [^4]. Commercial lender BCP offered retail rates of 3.525 soles buy and 3.540 soles sell on 12 October [^5].

Banco de México meeting minutes have strengthened market expectations of further interest rate cuts, which would reduce the peso's investment attractiveness [^6]. Laura Clavijo, Bancolombia Head of Economic Research, estimated the fair exchange rate value for the Colombian peso at 3600 COP per US dollar [^7].
