Shares of Singapore’s major banks have come under significant pressure in recent weeks, raising questions about the city-state’s reputation as a financial safe haven amid global market turbulence. The Straits Times Index (STI), which had been one of Asia’s stronger performers this year, has dropped 6.6 percent from its peak over the past five weeks, driven largely by declines in DBS Group Holdings, Oversea-Chinese Banking Corporation (OCBC), and United Overseas Bank (UOB). Together, these lenders make up more than half of the benchmark index, and their combined market value fell by approximately US$22.4 billion last week alone.

Market participants attribute the sell-off to growing concerns about the banking sector’s near-term outlook. Rising bond yields have dampened the attractiveness of the banks’ dividend returns, while potential losses on their bond holdings are expected to weigh on upcoming earnings reports. These factors have prompted several Wall Street firms to issue warnings about downside risks. For instance, JPMorgan Chase highlighted that higher long-term bond yields could lead to significant mark-to-market losses on banks’ trading portfolios, as well as negatively impact capital-raising activities for Southeast Asian financial institutions.

Other major global banks have taken a cautious stance on Singapore’s banking sector: Citigroup downgraded OCBC to a sell rating and maintained a sell rating on UOB, while HSBC revised its outlook on Singapore stocks to neutral, citing stretched valuations and pressure on the real estate sector due to tightening financial conditions.

Despite the recent sell-off, Singapore’s banking shares remain relatively expensive compared to regional and global peers. DBS, the largest lender in Singapore, continues to trade at about 16.9 times its projected 12-month forward earnings, well above the MSCI Financials index average of 13.2 times.

Some analysts warn that the risk extends beyond the banking sector, with potential for broader market declines if banks’ earnings or capital distributions weaken significantly. “The risk is a longer sell-off that spreads beyond the banks, or earnings and capital returns that start to weaken,” said Alex Ho, a sales trader at CMC Markets Singapore. Upcoming earnings results in November are regarded as a key test for the sector.

Nevertheless, not all investors share a pessimistic view. Some strategists point to Singapore’s solid economic growth prospects and government initiatives aimed at invigorating the equity market as factors that could limit further downside risk. Jen-Ai Chua, an Asia equity research analyst at Julius Baer, noted that there are currently no clear signs of rising bad loans, a typical hallmark of banking sector downturns, while loan growth remains steady. She added that the market may continue to experience volatility during October, but fundamentals do not yet point to a broad-based crisis.

As Singapore’s financial sector navigates these headwinds amid ongoing global uncertainties, investor focus remains firmly on the upcoming earnings season to gauge the resilience of the banking sector and its wider implications for the STI benchmark.
