Singapore SGS bonds are tradeable government bonds issued by the Monetary Authority of Singapore (MAS) that pay you a fixed coupon twice a year for terms running from 2 up to 50 years. They sit alongside Singapore Savings Bonds and Treasury bills, but they behave differently: the coupon is locked in at the auction, the price moves daily on the secondary market, and you can lose money if you sell before maturity when yields have risen. As of June 2026 the 10-year SGS benchmark yield was hovering near 2.0%. This guide walks through what you actually get, the minimum you need, the auction mechanics, and whether an SGS bond beats the Savings Bond or a fixed deposit for your money.
SGS stands for Singapore Government Securities. An SGS bond is a marketable bond: MAS borrows your money, pays you a fixed coupon every six months, and returns your principal at maturity. Because Singapore carries a AAA credit rating from all three major agencies, the credit risk on these bonds is about as low as it gets in the bond world.
Three families exist. SGS (Market Development) bonds are the bread-and-butter issues sold to deepen Singapore's bond market, with tenors of 2, 5, 10, 15, 20, 30 and (more recently) longer. SGS (Infrastructure) and Green SGS (Infrastructure) bonds are issued under the SINGA framework to fund major long-term projects, with tenors stretching to 50 years; the green issues fund environmentally focused infrastructure. For an individual investor they trade and pay coupons the same way, so the choice comes down to the tenor and yield on offer.
The word 'bond' here matters. Unlike a Singapore Savings Bond, an SGS bond has no capital-protection feature. Its price floats on the open market, so the moment yields move, the resale value of your bond moves the other way.
The minimum to buy an SGS bond at auction is S$1,000, and you bid in multiples of S$1,000. The coupon is fixed for the life of the bond and paid twice a year, so a 10-year bond pays 20 coupons in total before returning your principal.
Yields are set at each auction and shift with the wider rate environment, so date-stamping matters. As of 17 June 2026 the 10-year SGS benchmark yield was around 2.0%, down from the roughly 3% level that prevailed through 2024. For comparison, the June 2026 Singapore Savings Bond tranche carried a 10-year average return of about 2.11%. Always check the live auction or the daily SGS prices on the MAS website before you bid, because the figure you read in any article is a snapshot, not a promise.
There are two doors in: the primary auction and the secondary market. At auction you apply through the ATM, internet banking or a branch of DBS/POSB, OCBC or UOB. On the secondary market you trade existing bonds through those same banks or on the Singapore Exchange (SGX) through your brokerage, paying the price the market sets that day.
You can fund an SGS bond purchase with cash, SRS or CPFIS-OA funds. Using SRS is popular because it lets idle SRS cash earn a government-backed yield instead of the token 0.05% it otherwise sits at. Using CPF is allowed under CPFIS-OA, but weigh the SGS yield against the CPF OA's own 2.5% floor before you move the money out.
SGS bonds are sold through a uniform-price auction. You can place a competitive bid, where you state the maximum yield you will accept, or a non-competitive bid, where you skip the guesswork and accept whatever yield the auction settles at.
Non-competitive bids are filled first, up to a published cap, before the remaining bonds are allotted to competitive bidders from the lowest yield upward. The auction stops at a single cut-off yield, and everyone, whether they bid competitively or not, receives that same cut-off yield. For most retail investors a non-competitive bid is the simpler route: you get the market-clearing yield without risking being shut out by pitching too aggressive a number.
If demand is heavy, non-competitive bids can be scaled down (allotted on a pro-rated basis), so a large order may not be fully filled. You can model what a given coupon does to your money over the years with the compound interest calculator.
Bond prices and yields move in opposite directions. If interest rates rise after you buy, newer bonds pay more, so the market value of your older, lower-coupon bond falls. Sell then and you book a capital loss. If rates fall, your bond is worth more and you could sell at a gain.
Hold an SGS bond to maturity and this price swing does not bite: you collect every coupon and get your full principal back (barring a Singapore government default, which the AAA rating makes extraordinarily unlikely). The price risk only matters if you might need to cash out early. This is the single biggest difference from a Savings Bond, which you can always redeem at face value with no capital loss.
All three are MAS-issued and government-backed, but they suit different jobs. SGS bonds lock in a long-dated fixed coupon. Singapore Savings Bonds give you flexible, penalty-free exits with no capital loss. Treasury bills are short zero-coupon instruments sold at a discount.

| Feature | SGS bonds | Singapore Savings Bonds | T-bills |
|---|---|---|---|
| Tenor | 2 to 50 years | Up to 10 years | 6 months or 1 year |
| Return form | Fixed semi-annual coupon | Step-up interest, paid every 6 months | Bought at discount, no coupon |
| Minimum | S$1,000 | S$500 | S$1,000 |
| Capital loss if sold early | Yes, price moves with rates | No, redeem at par anytime | Possible if sold before maturity |
| Early exit | Sell on secondary market | Monthly redemption, no penalty | Sell on secondary market |
| Fund with | Cash, SRS, CPFIS-OA | Cash, SRS (no CPF) | Cash, SRS, CPFIS-OA |
| Holding cap | None | S$200,000 per person | None |
An SGS bond fits if you want to lock in the current yield for a long horizon and you are confident you will not need the money before maturity. Retirees building a ladder of fixed coupons, or anyone matching a known future liability (a child's university bill in 15 years, say), are the natural fit.
If you might need the cash at short notice, or you cannot stomach seeing a paper loss when rates jump, a Savings Bond or a fixed deposit is the calmer choice. Compare the running rates first using our best fixed deposit rates guide and the fixed deposit vs investing calculator before committing your money for a decade or more.
SGS bonds are backed by the Singapore Government, which holds a AAA credit rating from all three major agencies, so the risk of default is extremely low. The real risk is price risk: if you sell before maturity after rates have risen, you can book a capital loss. Held to maturity, you get every coupon and your full principal back.
The minimum bid at an SGS bond auction is S$1,000, and you invest in multiples of S$1,000. There is no maximum holding limit, unlike Singapore Savings Bonds which cap you at S$200,000 per person across all tranches.
Yes. You can fund SGS bonds with cash, SRS funds, or CPF Investment Scheme Ordinary Account money. SRS is a common choice for idle SRS cash. If using CPF, compare the SGS yield against the CPF Ordinary Account's guaranteed 2.5% before moving the money out.
SGS bonds pay a fixed coupon, run as long as 50 years, and trade at a market price that can fall below what you paid. Singapore Savings Bonds have a step-up rate, a 10-year tenor, and can always be redeemed at face value with no capital loss, but are capped at S$200,000 per person.
