What this choice actually costs you
The exit test: month eleven of a twelve-month plan
Wei Lin parks $10,000 for a renovation planned in a year. A 12-month FD at 3.2% will pay her $320 at maturity; an SSB issue averaging 3% pays a touch less in its first year. On paper, the FD wins.
Then the contractor calls: payment due in month eleven. Breaking the FD forfeits accrued interest at most banks: she walks away with roughly her $10,000 and little or nothing else. Redeeming the SSB instead: full principal plus around $230 of accrued interest, minus a $2 transaction fee, credited by the start of the next month.
That is the whole comparison in one phone call. The FD's extra yield is real, but it is payment for a lock, and life does not always respect the lock. Price the lock honestly before you take the higher headline number.
Ten years locked vs a renewal gamble every twelve months
An SSB fixes all ten years of coupons the day it is issued, in a step-up ladder: lower in year one, rising to above-average by year ten, engineered so your average yield grows the longer you hold. Rate cuts after purchase cannot touch it.
The FD path is different: a great 3.2% promo lasts its term, then you reinvest at whatever the market pays. When central banks ease, renewal offers step down, and a saver rolling 12-month FDs takes that repricing risk ten times in a decade. The chart shows the mechanics: the FD starts ahead, and each renewal is a coin-flip the SSB never has to take.
This cuts both ways, honestly: if rates rise, the FD roller captures the increase while the SSB holder is anchored. But an SSB holder is never truly anchored: redeem next month for $2 and buy the newer, higher-coupon issue. The FD breaker cannot do the reverse without burning interest. The asymmetry always favours the SSB.
Safety fine print, and the ladder that uses both
Both products are safe; the guarantees differ above $100,000. Bank deposits are insured by SDIC up to S$100,000 per depositor per bank: a $250,000 FD at one bank leaves $150,000 resting on the bank itself, not the scheme. SSBs are direct obligations of the Singapore Government at any amount within the $200,000 individual limit. For six-figure cash, that distinction is worth respecting: fill the SSB limit, then spread FDs across banks in $100,000 slices.
The practical entry mechanics: SSBs are issued monthly, applications run roughly the 1st to the 25th via DBS/POSB, OCBC or UOB internet banking or ATMs, you need a CDP account, and oversubscribed issues are allotted in $500 blocks, so large applications may be partially filled in popular months. Interest is paid every six months and is tax-free for individuals, as is FD interest at licensed banks.
The strategy most Singapore savers land on: emergency fund and undated goals into SSBs (staggered across a few issues so redemptions are granular), dated obligations into the best FD promo you can find for exactly that term, and every new SSB issue's rate checked once a month: if a new issue meaningfully beats one you hold, the $2 redemption fee makes upgrading nearly free. Interest from both products also stays outside your CPF and tax filings entirely, so there is no year-end admin either way.
