DBS, OCBC, and UOB reported net interest margins between 2.12% and 2.00% despite rate cuts and trade disruptions.

Average NIM of 2.1% Reflects Divergent Performance Across Banks

Singapore's three largest banks—DBS Group Holdings, Oversea-Chinese Banking Corp. (OCBC), and United Overseas Bank (UOB)—reported a simple average net interest margin of approximately 2.1% in the first quarter of 2025, based on disclosed quarterly figures. The headline NIMs ranged from 2.12% at DBS to 2.00% at UOB, with OCBC reporting 2.04% for the same period. The computed average of 2.053% rounds to 2.1%.

DBS posted the highest margin at 2.12% in Q1 2025, a decline of nine basis points year-on-year, though net interest income rose 2% as balance-sheet growth offset margin erosion. UOB held NIM steady at 2.00%, supported by 6% loan growth that lifted net interest income 2% year-on-year. OCBC reported a 23-basis-point drop to 2.04%, with net interest income falling 4% year-on-year. In August 2025, OCBC revised its full-year NIM guidance downward to 1.90–1.95%, citing headwinds from global trade disruptions and lower interest rates.

Deposit-to-Loan Spreads Cushion Impact of Easing Rates

The resilience of Singapore bank NIMs in 2025 was underpinned by structural dynamics in deposit-to-loan spreads. The US Federal Reserve cut rates by 25 basis points in December 2025, its third reduction of the year, yet domestic benchmark rates declined more gradually. The Monetary Authority of Singapore maintained its policy stance throughout 2025, limiting the pass-through of global rate cuts into Singapore-dollar lending rates.

According to SingaporeWallStreet analysis, deposit pricing remained competitive across the sector, preventing a rapid erosion of funding-cost advantages. This asymmetric adjustment—where deposit costs fell more slowly than loan yields—preserved net interest margins even as the absolute level of rates declined. Fitch Ratings noted that much of the margin compression had already occurred by early 2026, with any further narrowing likely to be modest.

The impact of US tariff policy on loan portfolios remained contained. As of 30 June 2025, nonperforming loan ratios across the three banks ranged from 0.9% to 1.6%, with coverage ratios between 88% and 156%. Banks assessed the direct impact of US tariffs on their loan books as limited, though second-order effects remained difficult to quantify given the evolving policy environment.

Bank Strategies: Hedging, Insurance, and Fee Income Offset NII Decline

Each of the three banks deployed distinct strategies to mitigate net interest income pressure, reflecting their diversified business models.

DBS leveraged hedging programmes to moderate NIM erosion through the rate cycle. The bank reported record total income of S$5.91 billion in Q1 2025 and record pre-tax profit of S$3.44 billion. Wealth management fees reached record levels, driven by Singapore's position as a regional wealth hub and growing affluence across Southeast Asia. DBS's geographic diversification across 19 markets provided additional revenue streams less correlated to domestic rates. The bank declared S$0.75 per share in dividends, including S$0.15 in capital return, up from S$0.54 a year earlier.

OCBC benefited from its integrated bancassurance model through subsidiary Great Eastern Holdings. Insurance earnings—dependent on underwriting discipline and investment performance rather than short-term rate movements—provided a natural hedge against banking cyclicality. Non-interest income grew 15%, fully offsetting the decline in net interest income. The bank's wealth management unit saw assets under management surge to a record high, while total non-interest income rose 10% in Q1, boosted by stronger fees, improved trading income, and better insurance performance.

UOB maintained stable NIM at 2.00% through a combination of loan growth and cost discipline. Net profit of S$1.5 billion was unchanged year-on-year. Net interest income increased 2%, supported by 6% loan growth across wholesale and retail banking. Net fee income rose 20% year-on-year to a record S$694 million. UOB held a Common Equity Tier 1 ratio of 15.5%, positioning it to absorb macroeconomic risks while maintaining dividend payouts.

Across all three banks, capital positions remained robust. As of 30 June 2025, transitional CET1 ratios ranged from 15.3% to 17.0%, while fully loaded ratios stood between 15.1% and 15.3%.

2026 Outlook: Further NIM Compression but Better than 2025 Pace

Analysts project continued NIM compression through 2026, though at a slower pace than in 2025. An RHB research analyst estimates net interest margins could narrow by approximately nine basis points year-on-year in 2026, compared with an estimated 17-basis-point decline in 2025. Under a base-case scenario with central banks cutting 50–100 basis points more over 2026, NIMs could compress an additional 10–20 basis points before stabilizing, according to analysis published by Maxthon.

Fee income is expected to provide a partial offset, with analysts projecting 8–12% growth in 2026 as capital markets activity improves. Loan volumes are forecast to increase 3–5%, with lower borrowing costs stimulating demand. Overall profitability is expected to decline 5–10% from 2025 peaks but remain well above historical averages.

The Monetary Authority of Singapore's policy stance is likely to remain accommodative, with firm domestic growth and gradually rising inflation limiting sharp declines in benchmark rates. Deposit pricing is expected to adjust in an orderly manner. Strong capital positions across the three banks—enabling continued hedging programmes and dividend maintenance—are expected to support profitability above long-term averages, even as the rate cycle continues to shift.
