Investing in Singapore's banking sector has proven highly rewarding over the past five years, with DBS Group (SGX: D05), OCBC Limited (SGX: O39), and UOB Limited (SGX: U11) shares posting significant gains.

Both DBS and UOB shares reached new historic highs yesterday, July 9, 2026, hitting S$70.27 and S$44.19, respectively.

This strong performance, however, has made their valuations appear less attractive than in the past.

This analysis explores key considerations for long-term investors, whether they are adjusting existing holdings or initiating new positions.

Drivers of the Banking Rally

The impressive multi-year surge in bank shares can be attributed to several key factors.

Elevated interest rates from 2022 to 2024 substantially widened the banks' net interest margins, leading to robust growth in net interest income and record-breaking profits.

Significantly, the banks have continued to report earnings near peak levels even as interest rates have moderated.

Their first-quarter results for 2026 demonstrate sustained, substantial profitability: DBS reported earnings of S$2.9 billion, followed by OCBC at S$2.0 billion and UOB at S$1.4 billion.

Returns on equity remained strong, with DBS leading at 17.0%, OCBC at 13.0%, and UOB at 11.5%.

Shareholders have also enjoyed a generally rising dividend trend over the past five years, further enhanced in some periods by special dividends and share repurchases.

These dividends are underpinned by robust capital positions, as evidenced by their high common equity tier one ratios: DBS reported 14.8%, while both UOB and OCBC reported 15.2% as of March 31, 2026.

Looking Beyond the Share Price

A high share price does not inherently signal overvaluation.

Investors must also evaluate the underlying earnings growth that has accompanied these record price levels.

If corporate earnings continue to expand, it is logical for the share price to rise accordingly.

Therefore, when observing record-high share prices, the pertinent question is whether fundamental business improvements have kept pace with the price appreciation.

Key Priorities for the Long Haul

Going forward, investors should monitor not just earnings growth but also the quality of those earnings.

Are the banks successfully expanding their non-interest income sources?

Dividend payout ratios also warrant attention; the three banks currently return approximately 50% to 60% of their earnings to shareholders as dividends.

Given their solid capital buffers and management's commitment to shareholder returns, these dividends are anticipated to persist.

Furthermore, all three institutions maintain prudent lending standards, reflected in high-quality loan portfolios.

This is most clearly seen in their low non-performing loan ratios, which range from 0.9% to 1.5%.

The Primary Threat: Declining Rates

The most significant risk for the banks is a sustained decline in interest rates, which would compress net interest margins and pressure net interest income.

However, this potential headwind could be mitigated by growth in fee-based income from wealth management, treasury activities, and, for OCBC, insurance contributions.

Additionally, further expansion across the region and the associated growth in loan volumes could help offset the impact of narrower margins.

Evaluating the Major Players

DBS Group distinguishes itself through digital banking leadership, increasing earnings diversification—especially from wealth management—and a capital return dividend program expected to continue through 2027.

OCBC Limited shows steady momentum in its wealth management operations and maintains a notably conservative balance sheet, with a non-performing loan ratio of 0.9%, the lowest among its peers.

The bank also provides business diversification through its insurance arm, Great Eastern.

UOB Limited offers investors exposure to the broader ASEAN economic region as it integrates its acquisition of Citigroup's regional consumer business.

While subject to execution risk, this acquisition could unlock future growth opportunities in regional banking.

Assessing Current Valuations

Valuations for DBS and OCBC have become more elevated following their strong share price rallies.

DBS now trades at 2.8 times book value and 17.6 times forward earnings, significantly above its five-year averages of 1.7x and 10.9x.

Similarly, OCBC's current price-to-book and forward price-to-earnings ratios of 1.9x and 15.1x are well above their historical averages of 1.2x and 9.6x.

These richer valuations are also reflected in dividend yields.

OCBC's trailing dividend yield is 3.6%, while DBS offers a trailing yield of approximately 4.4%.

UOB's valuation appears relatively less stretched.

The bank trades at 1.4 times book value and 11.8 times forward earnings, only slightly above its five-year averages of 1.2x and 9.5x.

It currently offers a trailing dividend yield of 4.1%.

Given that all three banks have delivered respectable and improving returns on equity, the current valuation levels may be seen as justifiable.

Timing the Market: To Wait or Not?

Investors could wait for a share price pullback to secure a more attractive valuation and a larger margin of safety.

However, building a position gradually over time is often a more prudent strategy than attempting to time the market perfectly. This approach allows investors to participate in potential future price appreciation while maintaining ownership in these high-quality banking businesses.

Pitfalls to Avoid

A common error is to avoid owning excellent companies simply because their share prices are at all-time highs.

That said, investors should remain conscious of current valuations and not make investment decisions based solely on dividend yield.

Most importantly, do not let short-term fluctuations in interest rates deter you from holding these fundamentally sound banks for the long term.
