Overview
- Many lenders now quote roughly 44–48.5% TNA for 30-day deposits, with Banco CMF at 55% and several at 46% (VOII, Provincia de Tierra del Fuego, Reba), versus lows such as 35% at Santander, 31% at Banco Ciudad and 25% at Masventas.
- Channel gaps are wide: at Banco Nación a 30-day placement pays 44% TNA via home banking but 29.5% in branch, yielding about $32,547.95 versus $21,821.92 in interest on $900,000.
- Banco Nación introduced a remunerated savings account that credits interest daily at a 29% annual rate, offering immediate access to funds in exchange for a lower yield than fixed terms.
- The BCRA publishes a comparative table of TNA/TEM/TEA that savers use to shop offers, and the difference between top and low rates can add more than $5,000 in one month on modest sums.
- Illustrative returns show the dispersion: at 44% TNA, $1,200,000 earns about $43,397 in 30 days, while earning $1,000,000 in a month requires roughly $26.4 million at 46% versus $48.7 million at 25%.
