OCBC has deployed its agentic AI platform HELIOS (Holistic Wealth Lifecycle Insights & Ongoing Surveillance) to redesign its customer due diligence process and support private banking onboarding under its AI, digital and data (ADD) agenda. The platform enables Bank of Singapore, OCBC’s private banking arm, to complete account opening in 15 business days, compared with an industry median of about six weeks. The deployment comes as regulators and banks seek to shorten private banking onboarding timelines while maintaining strong risk controls. The Monetary Authority of Singapore (MAS) is working with the Private Banking Industry Group to reduce account opening timelines to within one month by the end of 2026. OCBC’s approach moves due diligence earlier in the customer journey, allowing risk assessment and information gathering to begin before a relationship manager (RM) formally engages a prospective customer. Compliance moves ahead of the first client meeting Private banking onboarding traditionally follows a sequential process. RMs first identify and engage prospective clients, gather initial information and submit source-of-wealth documentation before compliance teams begin detailed screening and risk assessment. HELIOS changes this sequence by using intelligence gathering, relationship-network mapping and automated assessment capabilities to complete a significant portion of customer due diligence before an RM engages a prospective customer. OCBC said the system can gather at least 70% of the information required before the first client meeting. It then identifies the remaining gaps for the RM to clarify with the prospective customer. This gives RMs more complete information on a client’s background, source of wealth and potential risks before the first conversation, reducing repeated exchanges between customers, RMs and compliance teams. According to OCBC, HELIOS comprises five AI agents. Four have been rolled out, covering prospective customer research, onboarding recommendations, lead generation and independent checking. The fifth agent, which will support ongoing post-onboarding monitoring, remains under development. The prospective customer research agent searches information in multiple languages, including Chinese, Thai, Japanese and Arabic. It also draws on local and provincial news sources. This is important in cross-border private banking because corporate, legal and adverse-media information may be available only in local languages or local publications. The independent checking agent reviews information produced by the other agents and helps identify inaccurate information, unreliable sources or potential hallucinations before it is used in the review process. Human judgement remains central to the process. OCBC said RMs and internal review teams retain ultimate accountability for review, judgement and decision-making. Jason Moo, Chief Executive of Bank of Singapore, said the platform’s effectiveness comes from embedding compliance expertise into the system from the outset. “The beauty of the system was that it was built by compliance, not by the tech person or the business side, because they could already build their standards into the system,” he said. The approach reflects a key challenge for regulated institutions adopting AI: improving efficiency while preserving regulatory judgement and control. Bank of Singapore Market Head Justin Ho, who is already using HELIOS, said the platform can provide an in-depth report on a prospective customer’s source of wealth before onboarding begins. This keeps compliance and front-office teams aligned earlier and reduces the need to return repeatedly to customers for clarification of documentation details. OCBC cited one case involving a prospective customer with a past drug-related offence and prison term. The customer initially appeared to fall outside the bank’s risk appetite. HELIOS found further information showing that the individual had subsequently established a pharmaceutical company and undertaken charitable activity. The system presented this additional context for human review instead of making the onboarding decision itself. The example shows how the platform can give reviewers a fuller picture while leaving the final judgement with bank staff. Compliance becomes a relationship intelligence channel Beyond faster onboarding, HELIOS gives compliance teams a role in identifying potential business leads. OCBC said HELIOS can identify and surface high-quality leads to RMs by analysing customer information and relationship networks. The bank described this as a first for a Southeast Asian bank, with its compliance function providing leads to relationship managers. The capability maps relationships around a prospective client and identifies connections that may warrant further review by RMs. These may include associated entities, counterparties, suppliers and customers. The information can reveal potential relationships that may not be visible through a conventional onboarding review. This changes how compliance contributes to the wealth management process. The function can provide risk intelligence that supports relationship development alongside its traditional review role. Loretta Yuen, OCBC’s Head of Group Legal and Compliance, said HELIOS enables the bank to identify potential concerns earlier, assess financial crime risks more holistically and uncover connections that may not otherwise be obvious. She described the shift as a change in the role of compliance, from enabling business activity to also originating opportunities. Moo said the bank is prioritising speed and completeness during the early rollout. Around 50 clients have so far gone through HELIOS, but he said the immediate focus is on improving the quality and speed of onboarding, with usage expected to expand as the rollout progresses. OCBC said the objective is not to reduce compliance resources. Automation is intended to give compliance professionals more time for deeper analysis, advisory work and the review of insights produced by the platform. Scaling AI across the wealth lifecycle HELIOS is the latest deployment under OCBC’s broader AI, digital and data strategy. The bank expects to spend more than SGD 1 billion annually on technology over the next three years as it expands its digital capabilities. The platform builds on earlier AI initiatives in wealth management. OCBC’s generative AI coaching programme for wealth advisers doubled weekly customer appointments compared with peers who had not completed the programme and generated a 50% uplift in revenue compared with the previous three months. Bank of Singapore also previously deployed an AI-powered source-of-wealth tool embedded into KYC workflows. The tool reduced average preparation time for source-of-wealth reports from 10 days to one hour by automating information extraction, structuring and follow-up identification. HELIOS is initially being rolled out across Singapore, Hong Kong and Dubai, with the rollout at Bank of Singapore expected to be completed by the third quarter of 2026. The platform will subsequently extend to OCBC Premier Private Client customers in consumer banking by the end of the year. The bank also plans to extend HELIOS into ongoing customer monitoring. This would allow it to identify changes in customer risk profiles and support more timely compliance reviews. What comes next OCBC has demonstrated two applications of its Next Frontier strategy within the same month: an AI-enabled customer engagement model through Avatar banking by OCBC WoW and an AI-enabled compliance platform through HELIOS. The next challenge is execution at scale. Faster onboarding will need to translate into stronger client acquisition and conversion, while compliance-generated leads will need to demonstrate their value beyond initial identification. The larger test will be whether HELIOS can maintain accuracy, regulatory judgement and customer trust as it handles more complex cases and expands across customer segments. Its early deployment shows how compliance can become involved earlier in private banking relationships while retaining human accountability for decisions.
