Artificial intelligence has become the defining competitive battleground for Singapore’s banks. But while both DBS and OCBC are investing heavily in AI, their latest announcements reveal two distinctly different philosophies.
Under CEO Tan Su Shan, DBS is doubling down on enterprise-wide AI transformation, embedding generative and agentic AI across virtually every function of the bank. Meanwhile, newly appointed OCBC CEO Tan Teck Long is taking a more customer-centric approach, using AI to deepen wealth management relationships while continuing to invest heavily in human bankers.
Although both strategies aim to improve productivity and customer experience, they reflect different priorities for the next era of banking.
DBS: AI as the Operating System of the Bank
DBS has spent more than a decade building AI capabilities, giving it a considerable head start over many global peers.
Speaking this year, CEO Tan Su Shan said the bank’s AI and data initiatives generated approximately S$1 billion in economic value in 2025, demonstrating that AI is no longer an experimental technology but a core business driver. The bank has deployed more than 430 AI use cases supported by over 2,000 machine learning models across risk management, operations, customer service and software engineering.
The next phase is even more ambitious.
Rather than simply introducing chatbots, DBS is embedding generative AI and agentic AI into customer journeys and employee workflows. Internal platforms such as DBS-GPT allow staff to access institutional knowledge instantly, while AI assistants increasingly automate routine work and support decision-making.
Tan has repeatedly emphasised that AI should augment people rather than replace them. She argues that successful AI adoption requires cultural transformation, leadership commitment and responsible governance alongside technology investments.
For DBS, AI is becoming the operating system of the bank itself.
OCBC: AI that Enhances Human Relationships
OCBC’s latest announcements tell a different story.
Rather than focusing on enterprise-wide automation, the bank unveiled an AI avatar application designed specifically for wealth management customers. The digital assistant aims to improve client engagement and make financial advice more accessible while complementing relationship managers instead of replacing them.
Perhaps more revealing than the AI launch itself was what came alongside it.
OCBC announced plans to hire 600 additional relationship managers over the next three years, signalling that it sees AI as a tool that strengthens human advisory capabilities rather than substitutes for them.
Under CEO Tan Teck Long, the bank appears to be prioritising personalised service in one of Singapore’s fastest-growing banking segments—wealth management. AI becomes an enhancement to customer experience, while human expertise remains central to delivering advice and building trust.
Different Priorities, Same Destination
Although both banks embrace AI, their strategic emphasis differs.
DBS is investing across the entire organisation. AI is transforming software development, operations, risk management, compliance, internal productivity and customer service. Its long-term vision is to become an AI-native bank where intelligent systems support almost every business process.
OCBC’s recent initiatives are more outward-facing. AI is being applied where customers directly experience its benefits, particularly in wealth management, while the bank simultaneously expands its frontline advisory workforce.
The contrast reflects each institution’s competitive strengths.
DBS is leveraging years of technology investment to industrialise AI across the enterprise.
OCBC is using AI to differentiate its high-touch wealth management franchise without diminishing the value of human relationships.
What This Means for Singapore Banking
The divergence illustrates a broader trend across financial services.
The first wave of digital transformation focused on moving banking online. The next wave is about making every interaction smarter through AI.
DBS believes competitive advantage will increasingly come from embedding AI throughout the organisation to improve productivity and decision-making at scale.
OCBC believes AI’s greatest value lies in creating richer customer experiences while enabling bankers to spend more time on meaningful conversations.
Neither approach is mutually exclusive. In fact, they may converge over time.
Enterprise AI without exceptional customer experiences risks becoming invisible to clients. Conversely, customer-facing AI ultimately depends on strong internal data, infrastructure and governance.
The real winners will be banks that successfully combine both.
The Bigger Picture
Singapore’s banking leaders are no longer asking whether AI should be adopted—they are deciding where it creates the greatest strategic advantage.
DBS is betting that AI becomes foundational infrastructure across the entire bank.
OCBC is betting that AI enhances the human relationships that define premium banking.
Both approaches highlight an important reality: the future of banking is unlikely to be humans versus AI. Instead, it will belong to institutions that best combine artificial intelligence with human expertise to deliver faster, smarter and more personalised financial services.
