A puttable bond gives the bondholder — not the issuer — the right to sell the bond back to the issuer at a predetermined price before its maturity date, offering downside protection against rising interest rates or issuer credit deterioration. It’s the mirror image of a callable bond.

Key Takeaways
- The “put” option belongs to the investor, not the issuer — the opposite of a callable bond, where the issuer can force early redemption.
- Puttable bonds typically offer a slightly lower yield than an equivalent non-puttable bond, since the investor is effectively paying for the downside protection through a lower coupon.
- Singapore Savings Bonds (SSBs) function like a puttable instrument in practice — holders can redeem any amount, in any month, at face value plus accrued interest, with no penalty.
- True puttable corporate bonds are relatively uncommon in Singapore’s retail bond market compared to callable structures, which are more common among SGX-listed corporate and perpetual bonds.
- The put option becomes most valuable exactly when interest rates rise or an issuer’s credit risk deteriorates — precisely when investors most want the ability to exit.
What Is Puttable Bond?
A puttable bond has an embedded put option: on one or more specified dates before maturity, the holder can choose to sell the bond back to the issuer, usually at par value. This is a genuine investor-side right — the issuer must honour it if the holder chooses to exercise, unlike a callable bond, where the issuer holds all the discretion.
Because this optionality benefits the investor, a puttable bond’s fair value can be thought of as: value of a straight (non-optioned) bond + value of the embedded put option. Since the investor is receiving something valuable, the market typically prices puttable bonds with a slightly lower running yield than an otherwise identical bond without the put feature.
How Does It Work in Singapore?
Singapore Savings Bonds (SSBs) are the clearest real-world illustration for retail investors, even though they aren’t technically marketed using “puttable” terminology. An SSB holder can redeem any amount, in any month, receiving the full principal back plus accrued interest up to that point, with no penalty for early redemption — functionally very close to a puttable structure, since the decision to exit early sits entirely with the investor.
True corporate puttable bonds are rarer in Singapore’s retail market. Where they do exist, they’re often structured with put rights tied to specific dates or trigger events (such as a change of control at the issuer), rather than the “any month” flexibility SSBs offer.
Example
Consider a hypothetical 10-year puttable corporate bond with a put date at year 5, carrying a 3.5% p.a. coupon. If, by year 5, interest rates have risen and comparable newly-issued bonds yield 5%, the investor can exercise the put, redeem at par, and reinvest the proceeds into the higher-yielding new bond — instead of being stuck holding a below-market 3.5% bond for the remaining five years to maturity.
Advantages
- Downside protection in a rising-rate environment. The investor can exit and reinvest at a higher prevailing yield rather than being locked into a now-below-market coupon.
- Added flexibility and liquidity. Compared to a plain vanilla bond with no early-exit mechanism, a puttable structure gives the investor a built-in off-ramp.
- Effectively shorter holding-period risk. The realistic expected holding period can be shorter than the stated maturity, which can reduce duration risk for the investor.
Risks and Limitations
- Lower running yield. Investors give up some coupon income compared to a similar non-puttable bond, as compensation for the embedded protection.
- Secondary market liquidity can be thin. Not all puttable structures trade with deep liquidity between put dates in the Singapore market.
- Exercising the put isn’t automatic. Investors must actively submit redemption instructions within the specified window, or the opportunity is missed for that cycle.
- Issuer credit risk remains until settlement. The put option only protects you once it’s actually exercised and settled — credit risk is live up until that point.
Puttable Bond vs Callable Bond
| Aspect | Puttable Bond | Callable Bond |
|---|---|---|
| Option holder | Investor | Issuer |
| Typically exercised when | Rates rise / bond value falls (investor benefit) | Rates fall / issuer can refinance more cheaply |
| Yield vs a plain bond | Slightly lower (investor pays for protection) | Slightly higher (investor compensated for issuer’s option) |
| Singapore retail example | Singapore Savings Bonds function similarly | Common among many SGX-listed perpetuals and corporate bonds |
The Bottom Line
Puttable bonds hand the early-exit decision to the investor rather than the issuer. Singapore Savings Bonds already give retail investors this exact flexibility, worth remembering when comparing SSBs against fixed-term instruments like T-bills or fixed deposits.
