United Overseas Bank Limited

UOB generates recurring net interest income supported by a CASA ratio of approximately 58.5% in FY2025 and an 8.5 million-customer ASEAN franchise post-Citi integration. FY2025 total income fell to S$11.8B from S$14.3B in FY2024 as net interest margins compressed, illustrating rate-cycle sensitivity in the underlying income stream.

UOB operates across three segments (Group Retail, Group Wholesale Banking, and Global Markets) and has added wealth management and trade finance as growth verticals. All product lines are within banking and correlated to the same interest rate and credit cycle, with no segment above 50% but no truly uncorrelated revenue streams.

Singapore accounts for approximately 60% of group profit, with Malaysia, Greater China, Thailand, and Indonesia providing secondary contributions across UOB's 19-country network. No region outside Singapore contributes more than 10-15%, and the bank is targeting a more balanced 50% Singapore and 30% ASEAN contribution by 2026 as Citi integration synergies mature.

UOB's cost-to-income ratio stood at 43.5% in H1 2025, the highest among Singapore's three major banks (DBS 38.5%, OCBC 38.9%), indicating below-peer operating efficiency. The Citi integration added approximately 5,000 employees and integration costs that have weighed on the cost base, with operating leverage improvements expected as the integration matures.

Net interest income from the loan and deposit book provides the core recurring revenue, complemented by growing fee income from trade finance (trade loans +26% in FY2025) and wealth management (wealth income +14% in FY2025). The revenue base is mission-critical to commercial customers but remains sensitive to interest rate cycles and credit costs.
