JPMorgan Chase & Co. told clients to trim Singapore bank exposure after DBS Group, OCBC and United Overseas Bank shed 4 to 5 per cent in a single session, dragging the Straits Times Index down 3.5 per cent to 5,412.96 points on Thursday as long-bond yields jumped on oil-linked inflation fears.
The note landed in a market already debating whether record first-half profits left Singapore lenders priced for perfection. DBS, trading near 2.9 times forward book according to exchange data cited by regional brokers, fell 4.7 per cent to S$73.85 on Thursday before easing another 0.7 per cent to S$73.36 on Friday. OCBC lost 4.3 per cent to S$29 on Thursday and finished flat Friday, while UOB slid 5.2 per cent to S$40.25 then slipped to S$39.96.
Funding costs versus fee income
Higher US Treasury yields do not automatically lift net interest margins when deposits reprice faster than loans, DBS senior FX strategist Philip Wee noted in a Thursday commentary tied to diesel and petrol prices testing 2026 highs. Wealth-management pipelines that padded first-half earnings may also revert if volatile markets slow mandate inflows, the JPMorgan team argued.
OCBC bore the brunt of a Citi downgrade earlier in the week, with analysts questioning whether Singapore-dollar rate optimism was overstated. For SMEs on floating-rate working-capital lines, the equity story matters because tighter bank capital markets often coincide with stricter covenant reviews on renewal season.
Friday’s quieter tape
Singapore shares ended Friday down 0.2 per cent at 5,401.89 as regional bourses mixed. Yangzijiang Shipbuilding rose 3.2 per cent to S$5.10, helping the STI components stabilise even as financials treaded water. DBS remained the most valuable name on the board by turnover, with S$711.9 million traded across 9.7 million shares, signalling institutions still adjusting rather than exiting wholesale.
What investors watch before Q3 prints
Trading desks now focus on net interest margin guidance, credit costs on commercial real estate exposures, and whether wealth fees normalise from exceptional highs. MAS stress tests published last week flagged thousands of HDB borrowers who could turn cash-negative if rates stay elevated, a reminder that bank equity and household balance sheets move on the same slope.
Retail holders of the lenders through CPFIS portfolios will see the volatility in October statements even if dividends hold; the question is whether payout ratios survive if mark-to-market losses on bond books widen into year-end reporting.
