CIMB Bank Taps ACI Worldwide to Advance Payment Transformation

OMAHA, Neb. & SINGAPORE--(BUSINESS WIRE)--ACI Worldwide (NASDAQ: ACIW), an original innovator in global payments technology, today announced that CIMB Bank, one of ASEAN’s leading banking groups and Malaysia’s second largest financial services provider, has chosen ACI’s payment solution to converge all account-to-account transactions—real-time, ACH, RTGS and cross-border—onto a single future-proof payments platform. As the industry pushes toward ISO 20022 standardization, this new ISO20022-native compliant platform—which serves as the foundation for CIMB Group’s regional payments platform, starting from its headquarters in Malaysia—empowers the bank with richer data exchange, straight through processing and insights that enhance interoperability, security and compliance. With the new unified solution, CIMB Bank will reduce the complexity of managing siloed legacy systems to achieve greater efficiency and agility while minimizing cost and risk.

“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. Aligned with ISO 20022 and powered by our partnership with ACI Worldwide, CIMB is positioning itself at the forefront of next-generation banking,” said Ros Aziah, Group Chief Technology Officer, CIMB Bank.

CIMB Bank and ACI Worldwide were recently recognized at The Asian Banker (TAB) Global Financial Technology Innovation Awards 2025 in the “Best Corporate Banking and Payment Technology Initiative in Asia Pacific” category. In its evaluation, TAB highlighted the technological differentiation and customer-centric approach demonstrated by CIMB Bank and ACI Worldwide in this project, which not only enhances security, scalability, and performance but also future proofs the bank to adapt quickly to rising customer expectations and evolving regulatory mandates.

“ACI is proud to be the strategic partner behind CIMB’s full-scale payment transformation—a complex, end-to-end overhaul that unified CIMB’s payment operations across real-time, high-value, low-value, and cross-border transactions onto a modern, enterprise-wide ISO20022 platform — and we are honored that our successful partnership has been recognized with a prestigious industry award. This partnership is a testament to how forward-thinking banks like CIMB can lead in a digital-first economy in Malaysia and across ASEAN,” said Leslie Choo, Senior Vice President, Managing Director – APAC, ACI Worldwide.
