The three largest banks dominate Singapore's financial system, with combined market cap exceeding USD 169 billion at end of June 2024.

DBS, OCBC, and United Overseas Bank collectively controlled approximately 60% of Singapore's total banking assets and managed over SGD 1.2 trillion in customer deposits as of 2024, according to industry data compiled from multiple public sources. The trio's combined market capitalization stood at USD 169 billion at end-June 2024, reflecting their outsized influence within Singapore's financial system and the Straits Times Index, where they represented approximately 45% of the benchmark's weight in mid-2024.

Market Dominance in Assets and Deposits

The scale of the three institutions is best understood through their balance-sheet totals. DBS reported total assets of SGD 829 billion in 2024, followed by OCBC at SGD 625 billion and UOB at SGD 538 billion—a combined SGD 1.99 trillion in assets. This represents roughly 60% of all banking assets in the Singapore system, a share that has remained stable over the past decade as the banks have grown in lockstep with the broader economy. Customer deposits across the three banks exceeded SGD 1.2 trillion in 2024, providing a stable, low-cost funding base that underpins their lending and investment activities.

2024 Financial Performance: Fee Income and Profit Growth

The banks posted robust profitability in 2024, powered by fee-income expansion and higher trading revenues rather than lending margins. DBS reported total income of SGD 22.3 billion and a record net profit of SGD 11.41 billion, with return on equity (ROE) reaching 18%—among the highest of developed-market lenders. Wealth management was a standout driver: DBS's wealth-management fee income surged 45% year-on-year, supported by the bank's deployment of over 1,500 AI models across 370 use cases.

All three banks benefited from strong fee income and higher trading income, which offset a decline in net interest margins (NIM) as funding costs stabilised. Loan growth rebounded in 2024, with divergent trajectories emerging among the three. OCBC led with 9% year-on-year loan growth in the first half of 2025, driven by residential mortgages and corporate lending. UOB followed at 4%, supported by regional lending activity across ASEAN, while DBS recorded a more measured 3% increase, signalling cautious loan-book management amid uncertain economic conditions.

Capital Strength and Shareholder Returns

The banks' capital positions remain exceptionally strong, with Common Equity Tier 1 (CET1) ratios for all three exceeding 15%, well above the Monetary Authority of Singapore's systemic-buffer requirements. This capital strength has enabled generous shareholder returns even as balance sheets remain robust.

DBS raised its ordinary quarterly dividend to 60 cents per share and introduced a capital-return dividend of 15 cents per quarter for 2025 through 2027, reflecting surplus capital above regulatory needs. In November 2024, DBS also initiated a SGD 3 billion share buyback programme. Across the sector, analyst reports indicate that payout ratios are expected to increase to 60–70% in 2025, up from UOB's roughly 50% in 2023 and earlier years. The three banks' ability to sustain progressive dividends and buybacks while maintaining CET1 ratios above 15% underscores the structural strength of their balance sheets.

Digital Transformation and Regional Growth Outlook

The long-term growth trajectory of Singapore's big three banks is reflected in their asset expansion over the past decade. From 2014 to 2024, DBS's assets grew 88% (from SGD 441 billion to SGD 829 billion), UOB's rose 75% (SGD 307 billion to SGD 538 billion), and OCBC's increased 56% (SGD 401 billion to SGD 625 billion). This growth has been underpinned by sustained investment in digital transformation, with DBS's 1,500+ AI models serving as the most advanced example among the three.

Looking ahead, analyst ratings reflect differentiated outlooks. As of early 2026, DBS and OCBC carry "buy" ratings, while UOB is rated "hold." DBS has the highest target-price upside among the trio. A potentially significant tailwind is the possibility of capital inflows from Middle Eastern ultra-high-net-worth individuals seeking a stable banking jurisdiction, as Singapore continues to position itself as a safe harbour for regional wealth. The banks' strong capital positions, digital investments, and regional lending momentum position them for steady growth, though net interest margin pressure and divergent loan growth will require continued discipline in capital allocation and cost management.
