Key Takeaways
- Fixed income securities are a core asset class alongside equities, giving Singapore investors predictable income and capital preservation at maturity.
- In Singapore, the main fixed income instruments retail investors can access are SGS bonds, T-bills, Singapore Savings Bonds (SSBs), and corporate bonds listed or distributed through banks and brokers.
- Credit quality varies widely — SGS bonds carry the Singapore Government’s AAA rating, while corporate bonds range from investment-grade to high-yield.
- Bond prices move inversely to interest rates, meaning fixed income portfolios still carry interest rate risk despite their reputation as ‘safe’ investments.
- MAS and the Monetary Authority regulate the issuance and distribution of fixed income products sold to Singapore retail investors.
What Is Fixed Income Securities?
Fixed income securities are, at their simplest, loans turned into tradeable paper. When an investor buys a fixed income security, they are lending money to the issuer — the Singapore Government, a statutory board, a bank, or a corporation — in exchange for a promise of regular interest payments and the return of the original principal when the security matures. The ‘fixed’ in the name refers to the scheduled, contractually defined nature of these payments, in contrast to equities, where dividends are discretionary and prices float with no promised return of capital.
For Singapore retail investors, the fixed income universe has expanded significantly over the past decade. Where SGS bonds and T-bills were once mostly the domain of institutions, retail investors can now buy Treasury bills and SGS bonds directly through ATMs and internet banking via the primary auction, hold Singapore Savings Bonds with full flexibility to redeem monthly, and access corporate bonds either through retail bond offerings or bond funds and ETFs if the minimum investment size for direct corporate bonds (often SGD 250,000) is out of reach.
Fixed income securities matter in a portfolio because of what they are not: they are not equities. Their defined maturity and contractual interest payments provide a ballast against the volatility of stocks, and for retirees or investors nearing a financial goal, that predictability of return is often more valuable than the higher expected returns equities offer over the long run.
How Does Fixed Income Securities Work in Singapore?
Singapore’s fixed income landscape is layered by credit quality and accessibility. At the top sits Singapore Government Securities (SGS), long-dated bonds issued by the Singapore Government and considered essentially free of default risk given the government’s AAA credit rating and strong fiscal reserves. Treasury bills (T-bills) are the short-dated cousin, maturing in 6 or 12 months, auctioned regularly and bought by many Singaporeans as an alternative to fixed deposits. Singapore Savings Bonds (SSBs) are a retail-only instrument backed by the government, offering step-up interest rates over a 10-year tenor with full capital guarantee and the unique flexibility to redeem any month without penalty.
Below sovereign paper sit corporate bonds, issued by Singapore-listed companies, banks, and REITs to fund operations or refinance debt. These carry credit risk that varies by issuer — a bond from a blue-chip bank carries far less default risk than one from a smaller, highly leveraged property developer. MAS requires prospectus disclosure for most retail bond offerings and imposes minimum investment sizes on many corporate bonds specifically to limit retail exposure to products that may be harder for ordinary investors to assess for credit risk.
Across all these instruments, price and yield move in opposite directions. When the Fed or MAS tightens monetary policy and interest rates rise, existing fixed income securities with lower coupons become less attractive and their market prices fall, even though the issuer’s creditworthiness hasn’t changed. This interest rate sensitivity is why fixed income, despite its reputation for safety, still carries genuine price risk if sold before maturity.
Singapore investors can access fixed income through several channels. SGS bonds and T-bills are bought at primary auction via ATMs, internet banking, or a CPF Investment Scheme account, with no commission charged at auction. Singapore Savings Bonds follow a similar monthly application process, subject to an individual allotment cap that can be scaled back when demand runs high relative to the amount on offer. Corporate bonds, by contrast, are typically distributed through private banking channels or retail bond offerings accompanied by a prospectus, or accessed indirectly through unit trusts and bond ETFs that pool many issuers together, which lowers the minimum capital needed to build a genuinely diversified fixed income allocation.
Fixed Income Securities Example
A Singapore investor builds a SGD 60,000 fixed income allocation split three ways. SGD 20,000 goes into a 10-year Singapore Savings Bond with an average yield of around 2.9% per annum if held to maturity, chosen for its flexibility and capital guarantee. Another SGD 20,000 goes into a 6-month T-bill yielding roughly 2.6% at the latest auction, chosen for short-term liquidity. The remaining SGD 20,000 goes into an investment-grade Singapore bank bond yielding 3.4% over a 5-year tenor, accepting slightly more credit risk for a higher coupon.
Across the SGD 60,000 allocation, the investor earns a blended yield of roughly 3.0% per annum, receives semi-annual coupons from the SSB and corporate bond, and has staggered maturities so that capital becomes available at different points, rather than being locked up in a single long-dated instrument.
Advantages of Fixed Income Securities
- Predictable income. Coupon payments are contractually scheduled, giving investors a clearer sense of expected cash flow than dividend-paying equities.
- Capital preservation at maturity. Holding a bond to maturity returns the full principal (barring default), unlike equities where there is no guaranteed floor.
- Portfolio diversification. Fixed income often moves differently from equities, cushioning a portfolio during stock market downturns.
- A range of risk levels to choose from. Singapore investors can select anywhere from essentially risk-free SGS and T-bills to higher-yielding corporate bonds, matching the instrument to their risk appetite.
Risks and Limitations
- Interest rate risk. Bond prices fall when interest rates rise, which can produce a paper loss if the holder needs to sell before maturity.
- Credit/default risk. Corporate bond issuers can default, and Singapore has seen notable retail bond defaults in past years — this risk does not exist with SGS bonds or SSBs.
- Inflation risk. A fixed coupon loses real purchasing power if inflation runs above the bond’s yield over its life.
- Liquidity risk. Many Singapore corporate bonds trade thinly, making it harder to sell a large position quickly without moving the price.
- Reinvestment risk. When a bond matures or is called, reinvesting the proceeds at a lower prevailing rate reduces future income.

The Bottom Line
Fixed income securities give Singapore investors a toolkit for predictable income and capital preservation that equities simply cannot match, but the toolkit spans a wide range of risk — from essentially risk-free SGS bonds and T-bills to corporate bonds that can and occasionally do default. Building a sound fixed income allocation means matching the right instrument’s credit quality, tenor, and liquidity to your own time horizon and need for flexibility, not simply chasing the highest advertised yield.
Frequently Asked Questions
What are fixed income securities in simple terms?
Fixed income securities are debt instruments, such as government bonds or corporate bonds, where an investor lends money to the issuer in exchange for scheduled interest payments and the return of principal at a set maturity date.
Are Singapore fixed income securities safe?
Safety depends on the issuer. Singapore Government Securities, T-bills, and Singapore Savings Bonds carry essentially no default risk given the government’s AAA credit rating, but corporate bonds carry credit risk that varies by issuer and can result in losses if the issuer defaults.
What is the minimum amount to invest in Singapore fixed income securities?
Singapore Savings Bonds have a minimum investment of SGD 500, while SGS bonds and T-bills typically require a minimum of SGD 1,000, making government fixed income accessible to most retail investors.
Do fixed income securities lose value when interest rates rise?
Yes. Existing bonds with lower coupons become less attractive when interest rates rise, causing their market price to fall, even though the issuer’s creditworthiness has not changed — this is known as interest rate risk.
Can retail investors buy corporate bonds in Singapore?
Yes, though many corporate bonds carry high minimum investment sizes (often SGD 250,000) aimed at accredited investors, so retail investors more commonly access corporate bond exposure through bond funds or ETFs instead.
