In practice, Singapore green bond frameworks are commonly structured with reference to recognised voluntary standards such as the ICMA Green Bond Principles and, where relevant, the ASEAN Green Bond Standards (ICMA, 2021).

Our Methodology
The bonds and issuers in this guide were selected based on: (1) publicly verifiable green bond framework or issuance documentation; (2) issuer presence in the Singapore market; (3) relevance to different investor types — retail, institutional, and corporate. Yield ranges have been removed from the main table because secondary-market yields are volatile and vary by specific issue and date. Readers should verify current pricing independently.
How to Choose a Singapore Green Bond
- Define your investor type. Retail investors can access Singapore sovereign green bonds via SGX in smaller denominations. Most other green bonds require institutional minimums of SGD 250,000 or more.
- Check the framework and verification. Look for bonds with a Second Party Opinion (SPO) from an independent reviewer such as DNV, Sustainalytics, or CICERO. The ICMA Green Bond Principles are voluntary guidelines — alignment does not guarantee a specific return or risk level.
- Match your investment horizon. Green bond tenures range from 3 to 50 years. Short-duration bonds suit those uncertain about interest rate direction; long-duration bonds suit institutions with matching liabilities.
- Assess issuer credit quality. Singapore sovereign and statutory board bonds carry AAA ratings. Corporate issuers may carry lower ratings — check the credit rating before investing.
- Review use-of-proceeds carefully. Confirm what specific projects the bond funds and whether the issuer publishes impact reports.

FAQs
What is a green bond in Singapore?
A green bond is a fixed-income instrument where proceeds are exclusively used to finance or refinance projects with positive environmental outcomes. In practice, Singapore green bond frameworks are structured with reference to voluntary standards such as the ICMA Green Bond Principles and, where relevant, the ASEAN Green Bond Standards. Compliance is not legally mandated but is market-expected.
Can retail investors buy Singapore green bonds?
Retail investors can purchase Singapore sovereign green bonds (Green SGS) through SGX or selected banks, often in denominations from SGD 1,000. Most other green bonds are issued in institutional tranches (SGD 250,000+).
How are Singapore green bonds verified?
Issuers appoint an independent Second Party Opinion (SPO) provider — such as DNV, Sustainalytics, or CICERO — to verify that the bond’s framework and use of proceeds meet recognised standards. Post-issuance impact reports are also published by most Singapore green bond issuers.
What is the Singapore Green Bond Framework?
The Singapore Green Bond Framework, published by the Ministry of Finance in 2022, sets out the government’s approach to issuing sovereign green bonds, aligned with ICMA Green Bond Principles and the UN Sustainable Development Goals (MOF: www.mof.gov.sg/policies/fiscal/green-bonds/).
Are green bonds safer than regular bonds?
Green bonds carry the same credit risk as conventional bonds from the same issuer. The ‘green’ label refers to the use of proceeds, not to additional credit protection. Always assess issuer credit quality independently.
