Overview
- The BCRA online comparator updated Oct. 18–19 lists Reba Compañía Financiera at a 24% TNA and several other nontraditional lenders offering above 23%.
- Major banks report noticeably lower TNAs with Banco Provincia and Banco Macro around 21% for clients and Banco Nación about 19.25% for electronic placements.
- TNA is a nominal annual rate and monthly interest for a 30‑day deposit is roughly TNA × 30/365, so the headline percentage does not equal the exact month gain.
- Journalistic examples show practical differences: a 30‑day placement of $3,000,000 at 24% TNA yields about $59,178 while $4,500,000 at Banco Nación’s electronic rate yields about $71,198.63.
- Banks and digital lenders use short 30‑day fixed deposits to attract funds, so savers should verify the current rate, client status, minimums and contracting channel before placing money.
