The BCRA has approved a new methodology for calculating the benchmark exchange rate, currently provided for in Communication A 3500. It will become effective on January 1, 2026. This update enhances transparency and representativeness, helping market participants to operate under more equal terms.
The new methodology was developed by taking into account the opinions of different market sectors, as gathered during the public consultation launched by the BCRA on November 5, 2025.
This significant change promotes a fairer financial environment by replacing the previous scheme based on rate surveys with a methodology based on actual transactions weighted by volume. This new method for calculating the benchmark exchange rate increases the transparency and representativeness of the indicator, strengthening the robustness of the data used by financial institutions and domestic and international forward markets.
By implementing this measure, the BCRA is in line with the international standards adopted by other central banks worldwide, promoting greater modernization and objectivity in the calculation of the benchmark exchange rate for the benefit of all market participants.
