“Can a mid-sized Spanish regional bank successfully modernise its consumer finance infrastructure via cloud-native platforms (Mambu) while remaining a fully licensed, self-operated bank across deposits, lending, and cards?”
Ibercaja Banco is a traditional Spanish savings-bank-origin institution that has been incrementally modernising its technology stack. The most notable embedded-finance signal is its adoption of Mambu to power consumer finance, indicating a move away from legacy core systems for at least part of its lending book. It has published PSD2 open banking APIs via Redsys, exposing itself as a data and payment-initiation source for third-party fintechs and aggregators. The bank continues to offer a full suite of traditional banking products — mortgages, SME credit lines, corporate cards, FX — under its own brand with little evidence of third-party embedded finance vendors beyond Mambu.
Ibercaja Banco discloses Mambu (consumer finance core) as its banking provider, according to the Embedded Finance Index 2026.
Ibercaja Banco does not disclose a bank charter of its own; its banking services are provided through Mambu (consumer finance core).
Ibercaja Banco processes payments through Ibercaja Payments (self-operated).
Ibercaja Banco's cards are issued through Ibercaja Banco (self-issued).
Ibercaja Banco's lending and capital products are provided by Mambu.
