Bond Ladder Singapore — How to Build a Fixed Income Ladder (2026)
A bond ladder is a fixed income investment strategy where you divide your capital across bonds or fixed income instruments with staggered maturities — for example, 1-year, 2-year, 3-year, 4-year, and 5-year maturities. As each bond matures, you reinvest the proceeds into a new bond at the longest rung of the ladder, maintaining the laddered structure. For Singapore investors, bond ladders can be built using Singapore Savings Bonds (SSB), Singapore Government Securities (SGS), T-bills, or corporate bonds.

Why Build a Bond Ladder?
A bond ladder addresses two key fixed income challenges:
- Interest rate risk: Holding only long-duration bonds exposes you to price falls if rates rise. A ladder spreads duration so only a portion of your portfolio is exposed to any given rate environment.
- Reinvestment risk: Holding only short-duration instruments (e.g. all 6-month T-bills) means you may be forced to reinvest at lower rates when they mature. A ladder guarantees you participate in current high rates for the portion in longer-dated bonds.
A bond ladder provides predictable cash flows (maturing bonds at regular intervals) while maintaining flexibility to reinvest at prevailing rates.
How a Bond Ladder Works
Example Singapore bond ladder with SGD 50,000:
| Rung | Instrument | Amount | Matures |
|---|---|---|---|
| 1 | 6-month T-bill | SGD 10,000 | Oct 2026 |
| 2 | 1-year SSB | SGD 10,000 | Apr 2027 |
| 3 | 2-year SGS bond | SGD 10,000 | Apr 2028 |
| 4 | 5-year SSB | SGD 10,000 | Apr 2031 |
| 5 | 10-year SSB | SGD 10,000 | Apr 2036 |
When the T-bill matures in Oct 2026, you reinvest into a new 10-year instrument (or the longest rung you want). Over time, the portfolio consistently generates cash at each maturity and reinvests to maintain coverage across the yield curve.
Building a Singapore Bond Ladder
Singapore investors have excellent government-backed instruments for laddering:
- Singapore Savings Bonds (SSB): Flexible (redeem any month), step-up interest rates (longer holding = higher average yield), low minimum (SGD 500), up to SGD 200,000 per person. Ideal for the middle and long rungs. See our Singapore Savings Bonds guide.
- Singapore Government Securities (SGS): 2-year, 5-year, 10-year, 15-year, 20-year, and 30-year bonds. Tradeable on secondary market but held to maturity in a ladder. See our SGS guide.
- Treasury Bills (T-bills): 6-month (most common) and 1-year. Risk-free Singapore government paper. See our T-bill Singapore guide.
- Fixed Deposits: While not bonds, bank FDs with staggered maturities function similarly. See our Fixed Deposit Singapore guide.
- Corporate bonds: Higher yield but credit risk. See our Corporate Bonds Singapore guide.
SSB vs SGS vs T-bill Ladders
For most retail investors, an SSB-heavy ladder is simplest: no secondary market risk (SSB price doesn’t fluctuate), flexible redemption (useful if you need emergency cash), and step-up returns reward long holding. SGS bonds offer higher yields on longer maturities than SSB but are less flexible. T-bills anchor the short end of the ladder with the highest short-term risk-free rate.
Bond Ladder for Retirement Income
A bond ladder is particularly powerful for retirement planning. By matching bond maturities to your anticipated annual spending needs, you create a predictable income stream. Example: a retiree needing SGD 30,000/year builds a 10-rung ladder with SGD 30,000 maturing each year for 10 years. This eliminates sequence-of-returns risk for the fixed income portion of the portfolio, while equity holdings grow for the longer term.
Risks and Limitations
- Inflation risk: Fixed nominal returns lose purchasing power in high-inflation environments. Consider inflation-linked bonds or equities for the inflation-protection portion of your portfolio.
- Credit risk: For corporate bond ladders, issuer default can disrupt the ladder. Singapore government instruments have zero credit risk.
- Opportunity cost: In falling rate environments, shorter rungs of the ladder reinvest at lower rates, reducing overall portfolio yield.
- Complexity: Managing a multi-instrument ladder requires tracking maturities and reinvestment dates.
FAQ: Bond Ladder Singapore
What is a bond ladder and how does it work?
A bond ladder is a fixed income strategy where you buy bonds with staggered maturities (e.g. 1, 2, 3, 4, 5 years). As each bond matures, you reinvest into a new bond at the longest maturity, maintaining the laddered structure. This balances liquidity, interest rate risk, and reinvestment risk.
What instruments can Singapore investors use for a bond ladder?
Singapore Savings Bonds (SSB), Singapore Government Securities (SGS) bonds, Treasury Bills (T-bills), fixed deposits, and corporate bonds are all suitable. SSBs are the most flexible and retail-friendly option for the middle and long rungs.
How many rungs should a bond ladder have?
Common bond ladders have 5–10 rungs depending on your time horizon and the available maturities of instruments. A 5-rung ladder (1-2-3-5-10 years) is a practical starting structure for Singapore retail investors using SSBs and SGS bonds.
Is a bond ladder better than holding a bond ETF?
A bond ladder provides certainty of return of principal at each maturity and predictable income. A bond ETF has no fixed maturity — its price fluctuates with interest rates and its yield varies over time. For investors seeking predictable cash flows (e.g. retirees), a ladder is often preferable. For convenience and diversification, a bond ETF may suit.
Can I build a bond ladder with Singapore Savings Bonds?
Yes. SSBs are excellent for bond ladders because they have 10-year terms, step-up interest rates (higher average yield for longer holding), flexible redemption without penalty, and are backed by the Singapore government. You can build a ladder by subscribing to SSBs monthly and holding different cohorts to different maturities.
