Corporate Bond: Lending Money to a Company for a Fixed Rate of Return
How Singapore Investors Earn Predictable Interest Income Through Company Debt
A corporate bond is a debt instrument issued by a company to raise funds, under which the investor lends money to the issuer in exchange for regular fixed (or floating) interest payments, called coupons, and the return of the principal amount at maturity — making it fundamentally a loan to a business rather than ownership in it.

Key Takeaways
- Corporate bonds pay a fixed coupon rate, typically higher than Singapore Savings Bonds or SGS bonds, to compensate investors for taking on the issuing company’s credit risk.
- Singapore retail investors can access corporate bonds directly (minimum investment often $1,000–$250,000 depending on the issue) or indirectly through bond funds and bond ETFs listed on SGX.
- Credit ratings from agencies like Moody’s, S&P or Fitch (or the absence of a rating) are the single most important factor in assessing a corporate bond’s risk — unrated or high-yield bonds can offer 6%+ yields but carry meaningfully higher default risk.
- Corporate bond prices move inversely to interest rates: when Singapore and global interest rates rise, existing fixed-rate corporate bonds generally fall in price, and vice versa.
- Notable retail-accessible Singapore corporate bond issuers in recent years have included Astrea (private equity-backed bonds), Mapletree, CapitaLand, and various statutory boards and SGX-listed companies via public offers.
What Is a Corporate Bond?
When a company needs to raise capital — to fund expansion, refinance existing debt, or invest in new projects — it can either issue equity (selling ownership shares) or issue debt (borrowing money directly from investors). A corporate bond represents that second route: the company (the ‘issuer’) promises to pay bondholders a fixed coupon rate at regular intervals (usually semi-annually) and to repay the full principal, known as the face value or par value, when the bond matures.
For Singapore investors, corporate bonds sit between the near risk-free Singapore Savings Bonds (SSBs) and Singapore Government Securities (SGS) on one end, and equities on the other, in terms of both expected return and risk. Because a company could default on its obligations — something a government with taxing power is far less likely to do — corporate bonds typically pay a higher coupon than government bonds of similar duration, with the gap known as the ‘credit spread’.
Corporate bonds can be secured (backed by specific company assets) or unsecured, and can be senior (repaid first in a default) or subordinated (repaid only after senior creditors). These structural features materially affect both the yield offered and the recovery an investor can expect if the issuer runs into financial trouble.
How Do Corporate Bonds Work in Singapore?
Retail investors in Singapore have historically had limited direct access to corporate bonds, as many issues are structured for institutional or accredited investors with minimum investment sizes of $200,000 or more. However, several high-profile retail bond offers have opened this market up — Astrea bonds (backed by a diversified portfolio of private equity fund interests, structured by Temasek-linked Azalea Asset Management) have been offered to retail investors with minimums as low as $1,000, and have been heavily oversubscribed in past tranches.
Beyond direct retail bond offers, Singapore investors commonly gain corporate bond exposure through SGX-listed bond ETFs such as the ABF Singapore Bond Index Fund (which holds a mix of SGS and quasi-government bonds) or global bond ETFs covering investment-grade and high-yield corporate credit, as well as actively managed bond unit trusts available through platforms like Endowus, FSMOne, and various bank-distributed funds. These pooled vehicles solve the minimum investment size problem and provide instant diversification across dozens or hundreds of issuers, reducing single-issuer default risk.
| Bond Type | Typical SG Retail Access | Approx. Yield Range (2026) |
|---|---|---|
| Singapore Savings Bonds (SSB) | Direct, from $500 | 2.5% – 3.0% |
| Singapore Government Securities (SGS) | Direct via SGX or CPFIS, from $1,000 | 2.8% – 3.3% |
| Investment-grade corporate bonds | Mostly via funds/ETFs; some retail offers | 3.5% – 5.5% |
| High-yield / unrated corporate bonds | Mostly via funds; higher risk retail offers | 6.0%+ |

Corporate Bond Example
Suppose a Singapore-listed property group issues a 5-year corporate bond with a face value of $1,000 and a fixed coupon of 4.5% per annum, paid semi-annually. An investor who buys one bond at issue receives $22.50 every six months ($45 a year) in interest, and gets back the full $1,000 principal when the bond matures in 5 years — assuming the company does not default.
If interest rates rise after issuance and newly issued comparable bonds now offer 5.5%, the existing 4.5% bond becomes less attractive to new buyers, so its market price would typically fall below $1,000 (say to around $955) to make its effective yield competitive with the newer 5.5% bonds — this is the inverse price-yield relationship at work. An investor who holds to maturity and the issuer doesn’t default still receives the full $1,000 face value regardless of these price swings in between, which is why many retail bond investors plan to hold to maturity rather than trade bonds actively.
Advantages of Corporate Bonds
Predictable, contractual income. Unlike dividends, which companies can cut at will, bond coupon payments are a contractual obligation, giving investors more certainty over the income stream (absent default).
Higher yield than government bonds. Corporate bonds compensate investors with a credit spread over SGS and SSB yields, rewarding the additional default risk taken on.
Capital preservation focus. For investors prioritising return of capital over return on capital, investment-grade corporate bonds held to maturity offer a defined repayment date and amount.
Portfolio diversification. Bonds often behave differently from equities during market stress, and adding corporate bonds can reduce overall portfolio volatility, particularly in a balanced asset allocation.
Risks and Limitations
Default (credit) risk. The issuing company could fail to make coupon payments or repay principal, particularly for unrated or high-yield issuers; Singapore has seen notable defaults, such as Hyflux’s perpetual securities and medium-term notes, which left many retail investors with significant losses.
Interest rate risk. Bond prices fall when market interest rates rise, which can create mark-to-market losses for investors who need to sell before maturity.
Liquidity risk. Many Singapore corporate bonds trade thinly on the secondary market, making it difficult to sell before maturity at a fair price without a significant discount.
Call risk. Some corporate bonds are callable, meaning the issuer can redeem them early (often when rates fall), which can force investors to reinvest proceeds at lower prevailing yields.
Concentration risk in single-issuer bonds. Unlike a diversified bond fund, holding individual bonds from one or two issuers concentrates default risk — a lesson reinforced by the Hyflux and Swiber bond defaults in Singapore’s market history.
Corporate Bonds vs Singapore Government Securities (SGS)
| Factor | Corporate Bonds | Singapore Government Securities (SGS) |
|---|---|---|
| Issuer | Private or public companies | Singapore Government |
| Default risk | Varies by issuer credit quality — can be meaningful | Effectively zero — backed by the Singapore Government |
| Typical yield (2026) | 3.5% – 6%+ depending on credit rating | 2.8% – 3.3% |
| Retail accessibility | Limited — mostly via funds or select public offers | Good — direct access via SGX/CPFIS from $1,000 |
| Liquidity | Often thin on secondary market | Generally more liquid, actively traded |

The Bottom Line
Corporate bonds let Singapore investors earn a higher, contractual yield than government bonds by lending to companies rather than the state — but that extra yield comes with real credit, liquidity, and interest rate risk that the Hyflux and Swiber defaults made painfully clear. For most retail investors, accessing corporate bond exposure through a diversified bond fund or ETF, rather than individual issuer bonds, is the more prudent way to capture this asset class.
Frequently Asked Questions
Are corporate bonds safe in Singapore?
Safety depends entirely on the issuer’s credit quality. Investment-grade corporate bonds from strong, profitable companies carry relatively low default risk, while unrated or high-yield bonds carry meaningfully higher risk, as shown by past defaults like Hyflux.
What is the minimum investment for corporate bonds in Singapore?
It varies widely. Some retail public offers, like certain Astrea bond tranches, have had minimums as low as $1,000, while many institutional corporate bonds require $200,000 or more. Bond funds and ETFs typically have much lower minimums.
How do corporate bonds differ from Singapore Savings Bonds?
Singapore Savings Bonds are issued and guaranteed by the Singapore Government with step-up interest and the flexibility to redeem early without penalty, while corporate bonds carry issuer credit risk, usually have fixed terms without early redemption flexibility, but offer higher yields to compensate.
What happens if a corporate bond issuer defaults?
Bondholders become creditors in any restructuring or liquidation process and may recover only a portion of their principal, depending on the bond’s seniority and the company’s remaining assets — as seen in the Hyflux case, where retail bondholders received only partial recovery after a lengthy process.
Can I sell a corporate bond before it matures?
Yes, if it trades on a secondary market, but many Singapore corporate bonds are thinly traded, meaning you may need to accept a less favourable price to sell before maturity, especially during periods of market stress.
