Overview

• The BCRA’s September 4 table lists 55% TNA for 30-day fixed terms at Banco CMF and Reba, equivalent to roughly 4.58% monthly.
• Large banks show lower quotes: Nación and Macro at 47% TNA, Credicoop 47%, ICBC 47.7%, Provincia and BBVA 45%, and Santander 38%.
• At 55% TNA, a $1,000,000 deposit for 30 days generates about $45,205 in interest, according to published calculations.
• Following the 2024 removal of deposit-rate floors, banks freely reprice offers, with digital and non-client promotions often leading.
• The central bank publishes TEM, TNA and TEA to let savers compare real short-term returns, and many current quotes exceed 2025 inflation estimates reported by the market.
