Case Study: HSBC achieves 4x faster innovation with MuleSoft

HSBC turns to APIs to build the bank of the future

HSBC, one of the world’s largest banks serving over 40 million customers, faced rising regulatory pressure, higher customer expectations, and increased competition from fintechs. To remain a disruptor, the bank needed to securely unlock data from thousands of legacy systems, improve customer experience, and open new revenue channels by making core banking services available to internal and third‑party developers.

HSBC partnered with MuleSoft to adopt an API‑led approach, building reusable APIs for core services (cards, mortgages, payments), launching an Anypoint/API Community Manager developer portal, and enabling apps like Nudge and seamless third‑party integrations (e.g., embedded mortgage flows). The result: innovation accelerated 4x, development time fell by 75%, the portal spans 30+ markets and serves 30,000+ HSBC developers and thousands of external developers, with new functionality released every two weeks instead of quarterly.
