UOB posted net profit of SGD 1.4 billion ($1 billion) for the first quarter of 2026, up 2% quarter-on-quarter but down 4% year-on-year. Lower benchmark rates compressing lending margins have made fee, treasury, wealth, cards and trade-related income more important to earnings resilience. Wee Ee Cheong, deputy chairman and chief executive officer, said the bank had moved from integrating Citibank's regional consumer portfolio to deepening activity across the enlarged franchise, with the systems and platform work from the Citi acquisition now largely complete. "We are moving into the next phase now: unlocking the value of our enlarged customer base to reshape the group towards a more diversified, fee-driven mix anchored on connectivity, trade and cash, lifestyle solutions like credit cards, and wealth," he said. Net interest income fell 4% year-on-year to SGD 2.3 billion ($1.7 billion), while net interest margin (NIM) narrowed to 1.82% from 2.00% a year earlier. Net fee income rose 2% quarter-on-quarter to SGD 637 million ($470 million), driven by wealth management and loan-related fees, while trading and investment income rebounded on stronger treasury flows and market activity. The retail current and savings account (CASA)-to-deposit ratio stood at 58% and the wholesale ratio at 60%, while assets under management (AUM) rose 5% year-on-year to SGD 198 billion ($147 billion). The invested AUM ratio improved from 40% to 42%, wealth income expanded 6% and card billings grew 7%. The balance sheet remained stable, with the non-performing loan ratio at 1.5%, total credit costs at 26 basis points and Common Equity Tier 1 at 15.3%. Lower rates sharpen the fee-led shift NIM compression explains why UOB’s post-integration strategy now matters more. As lending margins fall, the bank must generate a larger share of earnings from the depth and activity of customer relationships, rather than from loan spreads alone. Leong Yung Chee, group chief financial officer, described the NIM movement as "consistent with the prevailing rate environment, but also offset by proactive management of our funding cost." UOB guided for full-year 2026 NIM of 1.75% to 1.80%, below the first-quarter level. Leong said margins had stabilised over the past two quarters and that any further downside should remain limited. The CASA deposit franchise gives UOB both a funding buffer and a commercial base for cross-selling. Leong said UOB's focus on CASA reflected lower deposit costs, stronger customer stickiness and more opportunities to cross-sell. Wealth and digital distribution test the fee opportunity Wee described the existing eight-million-plus customer base as the most immediate wealth opportunity, ahead of new client acquisition, arguing that competitors would find it harder to replicate that embedded regional scale. The improvement in investment penetration matters because moving more customers from deposits into investment products is central to UOB's wealth income target. Wee set a target of doubling wealth income by 2030, using 2025 as the reference point. The bank's immediate priorities include improving invested AUM penetration, strengthening advisory, investing in relationship manager talent and building cross-border capabilities across ASEAN and North Asia. Digital distribution should help UOB scale that effort beyond traditional relationship-manager coverage, including through smaller recurring investments on its app. UOB's approach to artificial intelligence (AI) also fits the bank's push to work smarter and more efficiently as it deepens relationships across its enlarged ASEAN franchise. "AI for us is not artificial intelligence, it's actually augmented intelligence," Wee said. About 30,000 staff now have Microsoft Copilot access, extending AI tools beyond specialist technology teams. UOB has also moved technology and innovation employees into Singapore's Punggol Digital District, where they will work on digital banking capabilities for ASEAN markets. The move supports the bank's efforts to serve more customers through digital channels, including UOB TMRW, its mobile banking app, while improving productivity, customer service and risk management. Trade, transaction and treasury support activity-led income Wee identified trade, CASA, transaction banking and cash management as the main opportunities in RWA-light wholesale banking, with liability management also central to the model. These businesses generate income from payments, cash management, trade finance, hedging and liquidity needs across the same regional client relationships. Trade loans grew 19% year-on-year, while wholesale customer treasury income rose 11%. The Johor-Singapore Special Economic Zone, where UOB has helped facilitate more than SGD 5.8 billion ($4.3 billion) in foreign direct investment, shows how regional connectivity can feed deposits, cash management, foreign exchange and advisory income. The same volatility that complicated the lending environment also supported client demand for hedging, treasury and trading solutions. Balance sheet discipline remains the guardrail UOB entered 2026 after a year of prudence and pre-emptive provisioning. That discipline remains central to the current strategy: the fee-led growth argument holds only if the bank avoids chasing volume at the expense of credit quality. Capital and liquidity remained strong, giving the bank room to support customers through uncertainty while maintaining discipline. Asset quality remained stable at group level, but UOB still faces pockets of risk. The bank identified Greater China real estate as a watchpoint, while direct Middle East loan exposure remained below 2% of the total book. UOB said it was watching second-order effects on energy costs, logistics, inflation, growth and demand. Leong said the bank would continue to monitor conditions and adjust its assumptions: "We need to be watchful and adjust accordingly if things deteriorate." The execution test With the heavy work of the Citibank integration largely complete, the harder task is now commercial rather than technical. Wee said UOB's 8.5 million customers should not be underestimated, noting that the customer base is now larger than Singapore's population and continues to grow. The bank must deepen those relationships in ways that generate recurring fee-led income fast enough to offset the decline in lending margins. UOB enters the next phase with the platform, customers and balance sheet to pursue the shift. The next few quarters will show whether the Citi integration can support a more durable, relationship-led ASEAN banking model.
