Should I Consider SBDEC25 GX25120E?
In a declining interest rate environment, banks are steadily adjusting their deposit rates. For instance, the UOB Stash Account is set to lower its interest rate to 1.5% per annum starting 1 December 2025.
If this downward trend continues over the next decade, the Singapore Savings Bonds (SSBs) become a compelling option. The current issue offers an effective return of 1.85% per annum when held for the full 10-year term, providing a relatively stable and predictable yield in contrast to falling bank rates.
All things considered, if no better alternatives emerge, this month’s SSB issue could be a worthwhile place to park my funds for the long haul.
