The 2025 results of DBS, UOB and OCBC mark a decisive shift in how leading banks in Asia Pacific generate earnings, even as the transition remains anchored in traditional banking structures. Across all three institutions, roughly two-thirds of income continues to come from net interest income (NII), with the remaining one-third derived from fees, trading and insurance. What has changed is how that one-third behaves, as it now stabilises earnings when interest rates fall by capturing client activity across payments, investments, hedging and advisory services.

Despite a broad decline in benchmark interest rates, income across the three banks remained resilient. DBS maintained net interest income at SGD 14.5 billion (~$10.7 billion) while expanding fee income by 18%. UOB delivered record fee income of SGD 2.6 billion (~$1.9 billion) even as margins compressed and provisions increased. OCBC offset a 6% decline in net interest income with a 16% rise in non-interest income, bringing its non-interest income share to about 37% of total income. These outcomes show that activity across wealth, treasury and transaction banking now supports earnings when spreads weaken, rather than acting as a secondary contributor.

In a global context, this places Singapore’s banks between traditional Asia Pacific lenders and more diversified United States (US) and European universal banks. They remain more reliant on lending spreads than the largest global banks, yet are significantly more diversified than many regional peers. This positioning allows them to combine the stability of deposit-funded balance sheets with the flexibility of fee-based income, strengthening performance across different rate environments.

Deposits expanded faster than loans across all three institutions, increasing liquidity that was actively redeployed into advisory, investment and treasury activity. Wealth management income, customer flow treasury income and transaction-related fees all grew, showing how deposits are no longer held passively but are used to generate multiple streams of income. The differences between the banks lie in execution, with DBS emphasising speed and scale of activity, UOB focusing on deepening client transactions across the Association of Southeast Asian Nations (ASEAN), and OCBC maximising conversion of deposits into wealth and insurance products.

Liquidity becomes the engine of earnings at DBS

DBS reported net profit of SGD 11.0 billion (~$8.1 billion) on total income of SGD 22.9 billion (~$16.9 billion) despite a significant decline in benchmark rates. Average Singapore Overnight Rate Average (SORA) and Hong Kong Interbank Offered Rate (HIBOR) fell by almost two percentage points, compressing lending spreads, yet net interest income remained stable, indicating that funding growth and balance sheet management offset margin pressure.

“Deposit growth outpaced loan growth, and surplus liquidity was deployed into high-quality liquid assets,” said chief executive officer Tan Su Shan. She added that “income came from volume and activity rather than spread expansion,” confirming that liquidity now drives earnings through client activity rather than pricing alone. Deposits increased by SGD 64 billion (~$47.3 billion), largely in current and savings accounts, providing a stable and low-cost base for generating flows.

This liquidity is converted into fee-generating activity through wealth and treasury channels. Assets under management (AUM) reached SGD 488 billion (~$360.5 billion), with SGD 39 billion (~$28.8 billion) in net new money inflows, while fee income rose 18% to SGD 4.9 billion (~$3.6 billion). Treasury customer sales and trading income increased significantly, reflecting higher client demand for hedging and investment solutions. Deposits move through a clear process in which funding is transformed into advisory, trading and investment activity, increasing the income generated from each unit of liquidity.

The bank’s designation as a renminbi (RMB) clearing bank strengthens its role within regional settlement flows, particularly as intra-Asia trade expands. Tan stated that this role “links to diversification of settlement currencies rather than displacement of the US dollar,” with RMB functioning as “an additional operating currency.” Settlement balances generated from trade and investment activity create demand for foreign exchange, liquidity management and hedging services, reinforcing DBS’s position in cross-border financial flows.

Artificial intelligence (AI) expands the capacity of this system. Tan described AI as “an operating model transformation rather than a discrete revenue product,” highlighting its role in increasing the volume of work that can be processed across credit and advisory functions. More than 60% of staff use generative AI tools, while chief financial officer Chng Sok Hui noted that “isolating the direct financial contribution is difficult” because value appears in productivity gains. This allows DBS to handle more transactions and client activity without a corresponding rise in costs, strengthening efficiency.

Regional connectivity and discipline sustain UOB performance

UOB’s results show how the same model operates with greater emphasis on transaction depth across ASEAN, where trade and cash management flows form a core part of banking activity. The bank reported net profit of SGD 4.7 billion (~$3.5 billion) and operating profit of SGD 7.7 billion (~$5.7 billion), with record fee income of SGD 2.6 billion (~$1.9 billion) and strong treasury and investment banking performance offsetting margin compression.

“Across ASEAN, momentum towards deeper integration is growing. Trade, capital flows and cross-border investment continue to expand,” said chief executive Wee Ee Cheong. Trade loans grew 26% to SGD 45 billion (~$33.2 billion), while transaction banking accounted for close to half of wholesale income, showing that a large share of revenue comes from payments, trade finance and cash management. In Asia Pacific, these activities contribute a higher share of income than in many global banks, reinforcing UOB’s positioning within regional trade corridors.

Group chief financial officer Leong Yung Chee explained that margin pressure reflected “asset repricing and keen competition,” while the bank strengthened buffers in anticipation of potential risks. “We pre-emptively anticipated these risks, and the buffers allow us to navigate potential hotspots,” particularly in commercial real estate exposures. This approach ensures that balance sheet risks do not interrupt client activity, allowing transaction flows to continue even under stress.

Wealth and digital channels reinforce these flows by expanding participation. Wealth income grew 14%, with assets under management reaching SGD 201 billion (~$148.5 billion), while digital platforms increased access to investment products. Wee noted that “digital wealth momentum in the mass affluent market remains very strong,” indicating that advisory services are reaching a broader client base beyond traditional private banking segments.

The model’s economics are most visible in cross-selling dynamics. Wee explained that “trade encourages cross-selling. If you do trade, you do foreign exchange, and you can package hedging and cash management. The broader wallet has implications for how we share the business.” Each client interaction therefore generates multiple revenue streams, increasing income per relationship and strengthening overall profitability.

Integration across wealth and insurance drives OCBC income

OCBC demonstrates the highest level of conversion within the flow-based model, where integration across banking, wealth and insurance allows the bank to capture a larger share of client activity. The bank reported profit before tax of SGD 9.12 billion (~$6.7 billion) and net profit of SGD 7.42 billion (~$5.5 billion), with non-interest income rising 16% as net interest income declined.

“Despite the challenges, the bank delivered a new high in income. We needed all cylinders firing,” said group chief executive officer Tan Teck Long. Deposits rose 10% to SGD 428 billion (~$316.0 billion), forming a substantial base of liquidity that can be converted into advisory and investment activity.

This conversion is evident in wealth performance. Invested assets exceeded 60% of total assets under management, while wealth management fees rose 33% to SGD 1.23 billion (~$0.9 billion), contributing more than half of total fee income. This shows a high level of effectiveness in turning deposits into investment mandates, placing OCBC at the more diversified end of Asia Pacific banks.

Group chief financial officer Goh Chin Yee highlighted the drivers of this outcome. “Record pre-tax profit was driven by record total income, well-managed expenses and lower allowances. Non-interest income more than compensated for the decline in net interest income.” He added that “wealth management fees and customer flow treasury income hit new highs,” confirming that client activity across investment and hedging channels is central to earnings.

Insurance adds a further layer of monetisation. Great Eastern contributed SGD 1.13 billion (~$0.8 billion) in profit, embedding long-duration income within the broader wealth ecosystem and increasing the share of recurring, capital-light income.

Technology and trade expand and scale the flow system

Across DBS, UOB and OCBC, the operating model follows a consistent sequence in which deposits increase liquidity, liquidity becomes operating balances, and these balances are used to generate income through wealth, treasury and transaction activities. DBS focuses on increasing the speed and scale at which this process runs, UOB deepens the number of transactions within its regional network, and OCBC maximises how much of each deposit is converted into higher-value products.

Artificial intelligence strengthens this system by increasing capacity. At DBS, widespread adoption of generative AI allows more credit, servicing and advisory work to be processed at the same time. UOB uses AI to improve response times and support digital distribution of wealth products across its regional franchise. OCBC applies AI to enhance how effectively deposits are converted into investment and insurance solutions.

Trade and settlement flows extend this system across markets. DBS’s renminbi clearing capability links settlement balances directly to foreign exchange and hedging activity. UOB’s trade growth reflects its role in regional supply chains, where transaction banking supports payments, liquidity management and trade finance. OCBC connects trade, wealth and insurance across its network, allowing a single client relationship to generate multiple forms of income. These dynamics reflect broader Asia Pacific trends, where strong deposit bases and intra-regional trade flows support the expansion of activity-driven income.

Strong asset quality supports the durability of the model

The sustainability of this system depends on maintaining asset quality while increasing activity levels. DBS absorbed a non-performing real estate exposure while maintaining strong allowance coverage, indicating that growth in flows has not weakened underwriting discipline. UOB set aside SGD 615 million (~$0.5 billion) in additional general allowances, prioritising stability and ensuring that transaction and advisory activity can continue without disruption. OCBC maintained a non-performing loan ratio of 0.9% alongside a fully phased-in common equity tier 1 (CET1) ratio of 15.1%, providing a strong capital base to support expansion.

Across all three banks, risk management supports the flow-based model by protecting liquidity generation and client activity rather than maximising loan growth. Balance sheets are managed to absorb volatility while sustaining the continuous cycle of deposits, flows and advisory income.

Flow based banking defines the next phase of growth

The 2025 results indicate that DBS, UOB and OCBC are converging towards a model in which competitive advantage is determined by how effectively liquidity is converted into multiple streams of client activity. Relative to global peers, they combine the balance sheet strength typical of Asia Pacific banks with a growing ability to generate fee-based income, positioning themselves between traditional spread-driven lenders and more diversified universal banks.

The next phase of competition will centre on three capabilities. The first is the ability to capture and retain operating balances linked to settlement and trade flows, particularly as intra-Asia trade continues to expand. The second is the efficiency of conversion, reflected in wealth penetration, treasury income and cross-product engagement. The third is the capacity to scale these activities through technology without a corresponding increase in costs. Banks that combine these capabilities will sustain stronger earnings quality, positioning themselves as core intermediaries of capital movement across an increasingly interconnected Asia Pacific financial system.
