Overview
- Banco de México’s FIX was 18.1903 MXN per USD, Colombia’s TRM was 3,273.49 COP per USD, and the Dominican Central Bank’s reference was RD$60.1698 buy / RD$60.6902 sell on Monday, October 5, 2026.
- Argentina’s informal markets moved lower that day with the blue closing at ARS 1,550 for sale and the MEP at about ARS 1,539.66 after falls of roughly 0.6 percent.
- Major Argentine banks showed mostly stable retail dollar quotes on the session, with Banco Nación, ICBC and Bica unchanged and Banco Provincia reporting a small drop, illustrating how bank windows can lag or differ from parallel rates.
- Reference rates are only benchmarks: banks, casas de cambio and digital platforms add spreads and fees and channels (cash, transfer, card, remittance) change the effective price a person or company pays or receives.
- The TRM is a certified average based on prior trading sessions, Banxico’s FIX is a settlement benchmark, and the BCRD posts buy/sell averages that can remain in force over weekends, so timing and method of calculation explain part of the gap between official numbers and retail quotes.
