Government Bond: Lending to the State for Singapore’s Safest Fixed Income Return

How Singapore Government Securities (SGS) Work and Why They Anchor Every Conservative Portfolio

A government bond is a debt security issued by a sovereign government to raise funds, under which the government promises fixed periodic interest payments and full repayment of principal at maturity. In Singapore, these are called Singapore Government Securities (SGS), widely regarded as the country’s lowest-risk investable asset because repayment is backed by the full faith and credit of the Singapore Government.

Key Takeaways

• Singapore Government Securities (SGS) Bonds have tenors of 2, 5, 10, 15, 20, 30 and 50 years, and are distinct from Singapore Savings Bonds (SSBs), which are a separate, more retail-friendly product.
• SGS yields serve as the benchmark ‘risk-free rate’ against which Singapore investors measure the attractiveness of S-REIT yields, corporate bond yields, and dividend stock yields.
• As at 2026, SGS 10-year yields have generally traded in the 2.8%–3.3% range, reflecting Singapore’s AAA sovereign credit rating from all three major rating agencies.
• SGS can be bought directly through SGX via a brokerage account, through CPFIS (using CPF OA/SA savings), or indirectly via bond ETFs such as the ABF Singapore Bond Index Fund.
• Unlike SSBs, SGS bonds generally cannot be redeemed early at face value — selling before maturity means selling at the prevailing market price, which can be above or below par depending on interest rate moves.

What Is a Government Bond?

A government bond is how a sovereign state borrows money from investors rather than, or in addition to, taxation. The government issues bonds with a stated face value, coupon rate, and maturity date; investors who buy these bonds receive regular coupon payments (usually semi-annually) and get their principal back when the bond matures.

In Singapore’s case, the Monetary Authority of Singapore (MAS) issues Singapore Government Securities (SGS) on behalf of the Government. Crucially, Singapore does not need to borrow to fund its annual budget — the government runs a structural fiscal position that does not require bond proceeds for spending. SGS is instead issued primarily to develop a liquid domestic bond market, to provide a risk-free benchmark yield curve for pricing other Singapore-dollar debt (including corporate bonds), and to support the investment needs of CPF funds, insurance companies and other institutions needing long-dated, risk-free assets.

This is an important nuance: because the Singapore Government does not need the money, SGS carries essentially zero default risk, reinforced by Singapore’s AAA credit rating from Moody’s, S&P and Fitch — one of a small handful of countries holding a top rating from all three agencies.

How Do Government Bonds (SGS) Work in Singapore?

SGS is issued across a range of tenors — 2-year, 5-year, 10-year, 15-year, 20-year, 30-year, and even 50-year bonds — through a regular auction calendar published by MAS. Retail investors can apply for new SGS issues through the same channels used for Singapore Savings Bonds (via ATMs, internet banking, or the SGX CPF Investment Scheme), with a minimum investment of $1,000, and can also buy existing SGS bonds on the SGX secondary market through a regular brokerage account.

Many investors confuse SGS Bonds with Singapore Savings Bonds (SSBs), but they are structurally different products. SSBs are specifically designed for retail investors, with step-up interest rates and the unique ability to redeem early in any given month without penalty (aside from a small transaction fee), receiving back the full principal. SGS Bonds, by contrast, are the standard tradable government bond and do not offer this early-redemption flexibility — selling before maturity means selling at whatever the secondary market price happens to be, which moves inversely with interest rates.

Government Bond Example

Suppose an investor buys $10,000 worth of a newly issued 10-year SGS bond carrying a coupon of 3.0% per annum. They will receive $150 every six months ($300 a year) in coupon payments for 10 years, and get back the full $10,000 principal at maturity, assuming they hold to term — a near-certain outcome given Singapore’s sovereign credit standing.

If the investor instead needs to sell this bond after 3 years, and market interest rates for comparable new 7-year SGS bonds have risen to 3.5% in the meantime, the market price of the original 3.0% bond would typically trade below its $10,000 face value (perhaps around $9,650) to make its effective yield-to-maturity competitive with the newer, higher-coupon bonds available. The investor would realise a capital loss on sale in this scenario, illustrating that even the safest bonds carry interim price risk if sold before maturity.

Advantages of Government Bonds (SGS)

Near-zero default risk. Backed by Singapore’s AAA sovereign rating, SGS is considered one of the safest fixed income instruments available to Singapore-based investors.

Benchmark for pricing everything else. The SGS yield curve is the reference point used to price corporate bonds, mortgage rates, and to assess whether S-REIT and dividend stock yields offer adequate compensation for additional risk.

CPFIS and institutional eligibility. SGS qualifies as an approved CPFIS investment and is a core holding for insurance companies and pension funds needing long-duration, risk-free assets to match liabilities.

Diversification against equity risk. Government bonds often provide portfolio ballast during equity market downturns, since they do not carry company-specific business risk.

Risks and Limitations

Interest rate risk. SGS prices fall when market interest rates rise, and longer-tenor bonds (like 30-year SGS) are considerably more sensitive to rate changes than short-tenor bonds, creating potentially large mark-to-market swings.

Low absolute yield relative to risk assets. SGS yields of roughly 2.8%–3.3% are meaningfully lower than long-term equity or REIT return expectations, meaning SGS alone is unlikely to meet most investors’ long-term wealth growth goals.

Inflation risk. Because SGS coupons are fixed, periods of unexpectedly high inflation erode the real (inflation-adjusted) purchasing power of both the coupon income and the eventual principal repayment.

No early redemption flexibility. Unlike SSBs, SGS cannot be redeemed early at face value — investors needing liquidity before maturity must sell on the secondary market at the prevailing price, which may be a loss.

Opportunity cost in rising-rate environments. Locking into a long-tenor SGS bond at a fixed rate means missing out if rates subsequently rise further, since the bond’s coupon doesn’t adjust upward.

The Bottom Line

Singapore Government Securities are the risk-free anchor of the local fixed income market, offering near-certain repayment backed by a AAA sovereign credit rating, and serving as the benchmark against which every riskier Singapore asset — from corporate bonds to S-REITs — is measured. The trade-off for that safety is a modest absolute yield and the loss of flexibility if you need to exit before maturity, which is why many retail investors prefer the equivalent-safety, more flexible Singapore Savings Bond for shorter-term savings goals.
