Treasury Bills (T-bills): What Are They And How You Can Buy Them

T-bills can be a good substitute for fixed deposit accounts

One of the simplest ways to keep your excess savings is to leave it in your bank savings account. But that may not give you sufficient returns to beat inflation over the long term, especially as some savings accounts may only give as low as 0.05% per annum (p.a.) interest.

On the other hand, savings accounts with higher interest rates, such as multiplier savings accounts, may not only give you less interest as you save more, but they may also make you jump through more hoops to get the higher interest rates.

One option to earn a higher return on your excess money is to invest in the Treasury Bills issued by the Singapore Government. These debt instruments allow you to earn a higher return that is based on the current market environment.

Here’s what you need to know about Treasury bills (T-bills) and how you can buy them in Singapore.

Treasury Bills (T-Bills) Are One Of The Four Types Of Singapore Government Securities (SGS)

The debt securities that are issued by the Singapore government are collectively known as Singapore Government Securities (SGS). These SGS are considered safe investments as they are fully backed by the Singapore government, which has the strongest credit rating accorded by international credit rating agencies, signifying the lower risk of default.

There are four types of SGS: Treasury bills (T-bills), SGS bonds, Singapore Savings Bonds (SSB), and Cash Management Treasury Bills (CMTBs).

Treasury bills (T-bills) are short-term bills that are offered in either a 6-month or 1-year tenor. They are also called “zero coupon bonds” because they don’t pay interest during the life of the bond. Instead, they are sold at a discount to their face value, which the investor will get back at full value upon maturity.

For example, if you applied successfully for $1,000 worth of 1-year T-bills at 2% interest per annum, you would only need to pay around $980. When the bond matures, you will receive the full lump sum of $1,000, which includes the $20 interest.

Treasury Bills (T-Bills) Are Issued To Develop Singapore’s Debt Markets

The Treasury bills and SGS bonds (Market Development) are issued by the government primarily to develop the local debt markets. The issuance of these bonds serves three main reasons.

The first is to build a liquid SGS market to provide a robust government yield curve to serve as a benchmark for the pricing of private debt securities.

Second, is to foster the growth of an active secondary market for both cash transactions and derivatives to enable efficient risk management.

And the third reason is to get both domestic and foreign issuers and investors to participate in the Singapore bond market.

Features of T-Bills

Treasury bills (T-Bills) have their own unique features, and here’s what you need to know.

The T-Bills can be bought by both institutions and individuals, including non-residents, over the age of 18 years old.

The minimum investment amount in T-bills is $1,000, with subsequent increments of $1,000. There is no maximum amount that an individual can hold, but there are limits—up to $1 million in non-competitive bids—for each auction.

The T-bills are sold on a uniform price auction method, which requires settlement within T+3 days.

T-Bills And SGS Bonds Are Sold Under A Uniform Price Auction Method

As opposed to the Singapore Savings Bond (SSB), which is based on a “quantity ceiling” format, the SGS and T-bills are issued via a uniformed-price auction. Successful bids or applications will be given out at the uniformed yield, which is the highest accepted yield (or cut-off yield) of successful competitive bids submitted at the auction.

When applying for T-Bills or SGS bonds, investors will be required to choose between making a competitive or non-competitive bid.

Competitive Bid Vs Non-Competitive Bid

A competitive bid is one that requires you to specify the price (to be expressed in terms of percentage yield, up to two decimal places) that you are willing to pay for the SGS bonds or T-bills. A lower yield represents a more competitive bid.

A non-competitive bid is one in which you do not need to specify a price and instead will be allotted the SGS bonds or T-bills at a uniform yield based on the results of the competitive tenders. This could be a better choice for retail investors, who might not know enough to put in a competitive bid.

Additionally, all non-competitive bids will be satisfied first, before the balance is then awarded to those who have submitted competitive bids. You stand a higher chance of securing your allotment with a non-competitive bid.

Should You Invest In T-Bills?

Given that individual investors can buy different kinds of bonds, here are some factors to think about if you want to add T-bills to your portfolio.

T-bills are a safe, short-term investment option that can be used for diversification of your investment portfolio. It allows you to receive a fixed interest payment at maturity.

Nevertheless, investments in T-bills or bonds generally might not generate sufficient returns to beat inflation in the long term. Therefore, the T-bills should be considered in totality with your other assets rather than being the only choice of investment.

Additionally, as the interest rates are determined based on a uniform-price auction, there is no certainty as to the interest rate that you will receive when you apply for T-bills. In the worst-case scenario, you may have to accept negative interest-bearing T-bills.

Lastly, selling the T-bills before maturity may result in losses as the bond prices may fluctuate depending on the market interest rate environment.
