Overview
- The BCRA board approved the new methodology through Communication “A” 8359, updating the framework governed by Communication A 3500.
- The TCR will be calculated from on-screen transactions in A3 Mercados using a volume-weighted average, counting only trades of US$500,000 or more and excluding RFQ and broker-channeled deals.
- The rule replaces the prior system that relied on banks’ quoted prices gathered at three points during each trading day.
- The A 3500 reference rate is published at the daily close and serves as a key benchmark for bank accounting, futures contracts, and dollar-linked instruments.
- Local reports noted that the official dollar fell for a third straight session and the blue rate closed below the official for a tenth consecutive day.
