Core Banking System

A core banking system is the back-end platform that processes deposits, loans, payments, and account updates for a bank. It serves as the system of record for customer accounts and balances.

Core systems handle transactions, interest calculations, and ledger postings across channels. Modern cores increasingly expose APIs for digital and fintech integrations.
