Case Study: Bank of Tokyo-Mitsubishi UFJ achieves an 18% increase in service re-utilization and faster service delivery with IBM WebSphere Message Broker on System z

Large Bank in Japan increases re-utilization rate by 18 percent

Bank of Tokyo-Mitsubishi UFJ, Japan’s largest bank with 40 million personal accounts and 500,000 corporate clients, needed to deliver financial services anytime, anywhere and on any device while relying on its existing IT assets. To build a scalable, non‑disruptive Service-Oriented Architecture, the bank partnered with IBM and adopted IBM WebSphere Message Broker together with Linux on System z as the platform foundation.

IBM implemented a SOA platform using WebSphere Message Broker on IBM System z (zEnterprise) with SUSE Linux, providing an MQ‑based, high‑throughput messaging backbone and active‑active scalability. The solution streamlined operations (for example, collapsing a nine‑step credit‑card screening into a single branch operation), linked to the Zengin clearing system, expanded use from 3 systems/9 services to 23 systems/150+ services in 2.5 years, and delivered an 18% increase in service re‑utilization—speeding service launches and improving productivity.
