How are Singapore Government Securities (SGS) bonds different from the existing Singapore government bonds and should you invest in them?


The Singapore Savings Bonds (SGS) may have gained a lot of traction in popularity lately due to rising interest rates, but there's also another government bond that you can buy: the Singapore Government Securities bonds, or SGS Bonds.

What lies behind the appeal of these SGS bonds? What is the coupon rate offered? And should you jump in and invest in them, too?

What are SGS bonds?

SINGA bonds, or SGS bonds, are investment bonds issued by the Singapore government on 28 September 2021.

The purpose of launching these bonds is to raise capital to fund upcoming infrastructure improvement, green infrastructure projects, and to develop the debt market. There are three SGS bonds: SGS (Market Development), SGS (Infrastructure), and Green SGS (Infrastructure), but more on these later.

Unlike the SSB, which has a 10-year tenure, SGS bonds are more flexible: you can buy 2-year, 5-year, 10-year, 30-year, and 50-year tenure bonds.

SGS bonds also pay a fixed coupon rate, which is paid twice a year, or every six months, on 1 October and 1 April. SGS bonds are issued every month with different interest rates.

How do SGS bonds compare against other Singapore government bonds?

Given that SGS bonds are issued by the Singapore government bonds, you may be wondering how they compare against other government bonds including the Singapore Savings Bond (SSB) and Treasury Bill (T-bill)

Three SGS Bonds in total

As mentioned, there are three SGS Bonds in total: SGS (Market Development), SGS (Infrastructure), and Green SGS (Infrastructure). 

The main purpose of SGS (Infrastructure) is to raise capital to fund upcoming infrastructure improvement and expansion needs.

Meanwhile, Green SGS (Infrastructure) will be used to fund major infrastructure developments that are considered to be better for the environment, such as railways. If that has got all those ESG investors excited, you’ll have to wait a little longer for the bond to be issued. 

Rounding out the trio is the SGS (Market Development) bond, which was the OG SGS Bond, now renamed to make room for its two new siblings. This bond continues in its original mission, which is to foster the development of Singapore’s debt market.

In a nutshell, the SSB offers more flexibility, as you can redeem your bonds early. However, do note that the coupon rate increases yearly, with the last two or three years enjoying the highest coupon rate.

This also means that early redemption will cause you not to achieve the advertised average coupon rate. However, SSBs require only S$500 to start investing, and you can freely increase your investment in any amount you wish. 

Last but not least, T-bills are short-term bonds that last for either six months or a year and are issued at a discount to their face value, and investors will receive the full face value at maturity.

On the other hand, SGS bonds don't offer early redemption, which could be an issue for investors sensitive towards the long tenor of 30 years. However, you are free to trade your holdings on the secondary market - if you’re willing to accept not receiving the face value of your bonds in return.

You’ll need a higher capital to start investing - S$1,000 at least, with increments in multiples of S$1,000. To fund your SGS (Infrastructure) investment, you can use cash, the monies in your Supplementary Retirement Scheme account, or the balances in CPF.

Should you invest in SGS Bonds?

Generally speaking, government bonds are considered one of the best ways to balance your portfolio, given their low volatility and tendency to be negatively-related to the equities market. As such, holding some government bonds will offer some needed stability when the markets are roiling. 

Of course, not all government bonds are created equal, and at the risk of sounding hyperbolic, SGS bonds are one of the safest bonds you can invest in. It has a rating of AAA, which probably has something to do with the fact that it is backed by the Singapore government itself.

On the flipside, if you buy bonds expecting excitement, prepare to be disappointed. However, if you look upon SGS bonds, especially SGS (Infrastructure) as a twice-yearly money drip for the next 30 years, you may come away more than satisfied.
