What Are T-bills In Singapore?

Before you learn how to buy T-bills in Singapore, you first need to know what it is. For those who want to earn a high return on their excess money, investing in SG T-bills that are issued by the government is an incredible idea.

These debt instruments do wonders to help individuals enjoy a high return based on the market environment.

Treasury bills are known as Singapore Government Securities or SGS, which are considered suitable investments since they are backed by the government. Singapore has a high credit rating according to international credit rating agencies, which means that the country has a low risk of defaulting.

There are four types of SGS: SHS bonds, Singapore Savings Bonds, Cash Management Treasury Bills, and Treasury bills or T-bills.

These are short-term bills that are offered in a 6-month or 1-year tenor. Another term for T-bills is “zero coupon bonds” since they don’t have an interest during the life of the bond. Instead, T-bills are sold at a discount to their face value. This means that investors will get back its full value upon the maturity of the T-bills.

For instance, if you learn how to buy Singapore treasury bills and were successful in getting S$5,000 worth of 6-month T-bills at 2% per annum, you only need to pay S$4,900. Once your T-bills mature, you will receive a S$5,000 lump sum, which includes S$100 interest.

Why do people clamor over how to buy Singapore T bills?

The government issues T-bills and SGS bonds mostly to build a liquid market and provide a robust government yield curve, which can serve as a benchmark for the corporate debt market.

Aside from that, it can also help grow a very active secondary market that works both for cash transactions and derivatives. This enables good risk management.

Finally, T-bills were launched to encourage investors and issuers in Singapore and all over the world to participate in the Singapore bond market.

In short, learning how to buy T bills Singapore is a way for individuals to lend money to the Singapore government so it can develop local debt markets.

How Does T-bill Work In Singapore?

On each issue, the T-bill interest rate changes and this rate is only determined during the auction.

As an example, we’ll take a look at the latest 6-month T-bill issued by MAS on 4 January 2024, which has a cut-off yield of 3.74% per annum. In comparison, it has a lower cut-off yield than the t-bill issues on 5 January of the previous year which was at 4.2% per annum.

Here’s more information about the T-bill issued on 4 January 2024.

Announcement date 27 December 2023
Auction date 4 January 2024
Issue date 9 January 2024
Maturity date 9 July 2024
Total amount allotted S$6.1 billion
Cut-off yield (T-bill interest rate) 3.74% per annum

What Are Competitive And Non-competitive Bids?

When understanding how to buy T bills Singapore, the T-bill competitive bid needs investors to specify the price that they’re willing to pay for the T-bills or SGS bonds. This should be expressed in terms of percentage yield up to two decimal places. A lower yield is equal to a more competitive bid.

Meanwhile, a non-competitive T-bill Singapore bid is one where investors don’t need to specify the price, they are willing to buy. Instead, they will be allotted SGS T-bills at a uniform yield based on the results of the tenders. This can be a great option for retail investors who still can’t get the hang of competitive bids.

Keep in mind that all non-competitive bids will be prioritised before the balance is awarded to people who have submitted competitive bids. Therefore, your chance of getting a T-bill will be higher if you secure your allotment through a non-competitive bid.

MAS allocates up to 40% of the total issuance of T-bills to non-competitive bids. Because of this, individuals who applied for non-competitive bids may not get the full allocation since only around S$1.92 billion in T-bills were released while the bids that were submitted totaled approximately S$2.4 billion. Therefore, the ratio of non-competitive bid allotment was only 77.78%.

So, if you made a non-competitive bid to buy T bills, you may only get half the amount you bid for.

Meanwhile, MAS allocates the remaining S$2.88 billion worth of issuance to competitive bids until the issuance has been fully allocated. The 3.9% per annum cut-off yield is derived from this.

When it comes to how to buy Singapore t bills, you never really know what the Singapore treasury bills interest rate will be after auctions are announced.

Thankfully, there’s a way you can estimate rates by looking at data from the MAS website.
