CIMB Bank, a Malaysian financial services provider, has partnered with ACI Worldwide to modernise its payments platform.

The collaboration will consolidate all account-to-account transactions onto one platform, enhancing efficiency and compliance for the bank’s operations, beginning from its Malaysian headquarters.

ACI Worldwide’s payment solution will serve as the “foundation” for CIMB Group’s regional payments platform.

This ISO20022-native compliant platform is set to enhance data exchange and processing for the bank, while offering insights to bolster interoperability, security, and adherence to regulations.

By unifying the payment infrastructure, the tech vendor anticipates increased operational agility and cost savings for the bank, through reduction in the complexity associated with managing disparate legacy systems.

The new platform is expected to deliver significant improvements in straight through processing for the bank.

CIMB Bank group chief technology officer Ros Aziah said: “CIMB’s payment transformation is a bold re-architecture of our core payments infrastructure to unify all payment flows.

“This enterprise-wide initiative is a cornerstone of our Forward30 Strategy, built to future-proof operations, accelerate digital convergence, and deliver seamless, secure, and intelligent payment experiences for both consumers and businesses.”

ACI Worldwide has half a century of experience in powering real-time payment schemes globally.

The paytech firm currently supports 26 domestic and pan-regional real-time schemes, including 11 central infrastructures across six continents.

CIMB Bank provides a comprehensive range of banking services, including consumer, commercial, wholesale, transaction and Islamic banking, as well as asset management.

The Kuala Lumpur-based lender had a market capitalisation of approximately RM75.2bn ($18bn) and 592 retail branch networks across ASEAN as of 31 March 2025.

It operates across Malaysia, Indonesia, Singapore, Thailand, Cambodia, Vietnam, Philippines, as well as beyond ASEAN in China, Hong Kong, and the UK.
