Reinventing credit risk management with integrated analytics and intelligent decisioning

In 2022, Singapore-based United Overseas Bank (UOB) acquired Citibank’s retail banking businesses in Indonesia, Malaysia, Thailand and Vietnam – its largest acquisition in two decades. The deal added millions of customers and accelerated UOB’s regional retail growth ambitions by five years.

“Integrating the former Citibank retail portfolio was a pivotal moment for UOB – not just in terms of scale, but in setting a new benchmark in extending our risk management capabilities at scale,” says Jagan Kanthadai, Managing Director, Group Retail – Credit Risk Management at UOB.

In Thailand alone, the portfolio more than doubled, requiring rapid integration of data, systems and decisioning processes without compromising governance or risk standards. To manage this complexity, UOB launched its Credit Portfolio Management program, combining advanced analytics, automation and decisioning to support retail credit at a regional scale.

“The Credit Portfolio Management program, powered by SAS for Risk Modeling and Decisioning, has redefined our approach to credit risk – enabling faster, sharper and more dynamic decision-making across markets,” Kanthadai says. “With automation and real-time analytics, we’ve improved our agility, strengthened governance and delivered measurable gains in portfolio performance and financial returns.”

A scalable credit engine built on SAS

At the core of the program is the Credit Portfolio Engine, built on SAS technology, including SAS Viya, and deployed on-premises. It provides a single foundation for designing, deploying and governing retail credit strategies across cards and loans.

By unifying data management, analytics and decisioning, the platform supports the full credit lifecycle. Business teams use low- and no-code tools to design and launch strategies independently, while daily behavior scoring and risk segmentation ensure timely, consistent assessments aligned with regulatory expectations.

Thailand went live in December 2023, completing rollout by March 2024, followed by Malaysia in early 2025 and expansion to Vietnam. Each market began with core use cases such as risk segmentation, collections and dynamic credit limit strategies before scaling further. The program is on track to break even within 12 months.

Built on the cloud-native architecture of SAS Viya, the platform supports SAS and open-source models. High-performance batch execution via SAS Cloud Analytics Services, automated ETL workflows using SAS Studio Engineer and business rules through SAS Intelligent Decisioning enable seamless operations. Automated deployment with full audit trails strengthens governance and security, while data extraction consistently exceeds service-level targets.

Strategic impact across the region

The program represents more than a technology upgrade. A new operating model allows business teams to develop, test and deploy strategies faster with less reliance on specialist resources.

“This isn’t just a credit decisioning tool – it’s a foundation for future growth,” Kanthadai says. “With SAS, we’ve built a strategic asset that allows us to continuously innovate, respond faster to market conditions and deliver real business value.”

Working with SAS and regional partners, UOB has implemented challenger strategies across retail portfolios, including secured and unsecured collections. Real-time analytics enable faster testing and refinement, improving portfolio performance and reducing expected credit losses. Shared tools and analytics have reduced silos, standardized decisioning across Southeast Asia and strengthened resilience through advanced segmentation and large-scale scenario simulations.

As UOB advances its digital transformation journey, the SAS-powered Credit Portfolio Management program demonstrates how banks can build scalable, intelligent and future-ready operations.

“This program has strengthened our ability to manage risk not just as a control function, but as a driver of strategic value,” Kanthadai says. “With the right tools, insights and operational agility in place, we’re now better equipped to deliver timely, data-driven credit decisions that support both resilience and growth across the region.”

“SAS Viya allows organizations like UOB to operationalize analytics and decisioning at scale – securely, efficiently and in real time,” says Craig Jennings, Regional Vice President, Financial Services (Asia Pacific), SAS. “What we’ve built together isn’t just a platform; it’s a launchpad for continuous innovation in risk, collections and customer management across the region.”
