The Sistema de Seguro de Garantía de los Depósitos (SEDESA) covers eligible Argentine peso and US-dollar deposits at BCRA-licensed banks up to a per-depositor per-institution ceiling published by BCRA Comunicación A. The ceiling is inflation-indexed and is updated periodically — it has been raised repeatedly since 2018 to track ARS inflation, so the headline figure on a third-party page can be out of date within months. Verify the current peso ceiling on bcra.gob.ar or sedesa.gob.ar before relying on the cover. Membership is statutory for BCRA-licensed banks: Ualá Banco S.A. — the post-Wilobank entity — is a SEDESA member, and an eligible peso deposit there sits inside the same statutory envelope as a deposit at Banco Galicia or BBVA Argentina.
PSP wallets are not SEDESA-covered. Mercado Pago, Brubank, and Naranja X operate as BCRA-supervised Proveedores de Servicios de Pago under Comunicación A 6885 and successors. The PSP regime requires customer funds to be held in segregated accounts at custody banks — segregation protects funds from the failure of the PSP itself, but it is not deposit insurance. Recovery in a PSP failure depends on the segregation arrangement and the custody bank, not on a state-backed compensation scheme. The brand on the app is the same family of products consumers use every day; the licence on the receiving entity is categorically different from a chartered bank's.
FCI / Rendimientos balances are not deposits at all. The peso money-market funds Argentine fintechs market as Rendimientos, Ualá Bis, or Mercado Pago Inversiones are FCIs (Fondos Comunes de Inversión) regulated by the CNV (Comisión Nacional de Valores), not bank deposits. They are investment products: returns can fall, the fund administrator carries the credit and operational risk, and the balance is NOT covered by SEDESA. Treating a Rendimientos balance as equivalent to a savings account is the single most common Argentine retail-banking misread — it is an investment in a CNV-regulated fund that happens to track short-tenor BCRA-regulated peso instruments, not insured savings.
