• Capital Guarantee: Since T-bills are issued by the Singapore government, your principal is fully guaranteed upon maturity.

How to Buy Singapore T-Bills: Step-by-Step Guide

Buying T-bills in Singapore is straightforward. You can invest using cash, Central Provident Fund (CPF) savings, or Supplementary Retirement Scheme (SRS) funds. Here is the complete step-by-step process:

Option 1: Buy T-Bills Using Cash

This is the most common method for retail investors. Follow these steps:

1. Check Auction Dates: Visit the MAS website (mas.gov.sg) to find the upcoming T-bill auction dates. Auctions are announced in advance, and you will need to submit your bid before the cut-off time.
2. Open a CDP Securities Account: If you do not already have one, you will need a Central Depository (CDP) account linked to your bank account. Most Singapore bank accounts can be linked to a CDP account.
3. Choose Your Bank: T-bill applications are submitted through your bank. Supported banks include DBS, OCBC, UOB, Standard Chartered, Maybank, and others. You can apply through internet banking, mobile banking apps, or in person at a branch.
4. Submit Your Bid: Log in to your bank’s internet or mobile banking platform and navigate to the T-bill application section. You can choose to submit a competitive bid (specifying your desired yield) or a non-competitive bid (accepting the average yield). Non-competitive bids are recommended for most retail investors.
5. Wait for Allotment: After the auction closes, MAS will determine the cut-off yield and allot T-bills to successful bidders. If you placed a non-competitive bid, you are almost guaranteed to receive your full requested amount.
6. Receive Your T-Bills: Successful allotments will be reflected in your CDP account. The T-bills will appear as a security holding.
7. Maturity and Payout: When the T-bill matures, the face value (S$100 per unit) will be credited directly to your linked bank account. The profit is the difference between the face value and your discounted purchase price.

Option 2: Buy T-Bills Using CPF Savings

You can use your Ordinary Account (OA) or Special Account (SA) savings to invest in T-bills. Here is how:

1. Check Your Investible Savings: Log in to the CPF Investment Scheme (CPFIS) portal or the CPF website to check your available investible savings. You must have at least S$20,000 in your OA or SA after setting aside the required basic amount.
2. Submit Application Through CPFIS Agent Banks: Applications for CPF-invested T-bills must be made through a CPFIS agent bank. The supported banks include DBS, OCBC, and UOB.
3. Follow the Same Auction Process: The bidding process is the same as for cash investments. Submit your application before the auction cut-off time.
4. Funds Automatically Deducted: If your bid is successful, the corresponding amount will be deducted from your CPF account.
5. Interest Earned Returns to CPF: When the T-bill matures, the proceeds and interest earned will be credited back into your CPF account.

Option 3: Buy T-Bills Using SRS Funds

If you have funds in your Supplementary Retirement Scheme (SRS) account, you can also use them to invest in T-bills:

1. Open an SRS Account: If you have not already done so, open an SRS account with one of the three participating banks (DBS, OCBC, or UOB).
2. Choose a SRS Operating Agent Bank: Select one of the SRS operator banks to handle your T-bill application.
3. Submit Your Application: Apply through the bank’s designated channel for SRS investments. Follow the same auction timeline as cash applications.
4. Proceeds Return to SRS: Upon maturity, the principal and interest will be credited back to your SRS account.

Eligibility Requirements for T-Bill Investment

To invest in Singapore T-bills, you must meet the following criteria:

• You must be at least 18 years of age.
• You must be a Singapore citizen, permanent resident, or a foreigner residing in Singapore.
• You must have a valid CDP account linked to your bank account.
• For CPF investments, you must meet the minimum investible savings requirement under CPFIS.
• For SRS investments, you must have sufficient funds in your SRS account.

Tips for Maximising Your T-Bill Returns

Here are some practical tips to help you get the most out of your T-bill investments in 2026:

• Use Non-Competitive Bids: Unless you are an experienced investor who closely monitors interest rate movements, non-competitive bids are the simplest and most reliable option. You are virtually guaranteed to receive your full allotment.
• Ladder Your Investments: Consider staggering your T-bill purchases across different auction dates to create a regular cash flow. This way, you always have T-bills maturing at regular intervals.
• Reinvest at Maturity: When your T-bills mature, reinvest the proceeds into a new T-bill auction to keep your money working for you.
• Compare With Other Options: While T-bills are excellent for short-term parking of funds, always compare the yields with Singapore Savings Bonds, fixed deposits, and other low-risk instruments to ensure you are getting the best return for your risk tolerance.
• Track Auction Dates: Keep a calendar of upcoming T-bill auctions so you never miss an opportunity. Bookmark the MAS website for the latest auction announcements.
• Consider the Opportunity Cost: Since T-bills cannot be redeemed early, ensure you will not need the funds during the tenor period. Match the T-bill tenor to your cash flow needs.

Frequently Asked Questions About Singapore T-Bills

1. Is it safe to invest in Singapore T-bills?

Yes, Singapore T-bills are among the safest investments available. They are issued by the Singapore Government, which holds a AAA credit rating from all three major credit rating agencies. Your principal is guaranteed upon maturity, and there is virtually zero default risk.

2. Can I lose money on T-bills?

If you hold your T-bills until maturity, you cannot lose money. You will receive the full face value of S$100 per unit. The only scenario where you could receive less is if you sell the T-bill on the secondary market before maturity at a price lower than what you paid. However, most retail investors simply hold T-bills to maturity.

3. How much can I invest in T-bills?

There is no maximum limit for individual T-bill investment. The minimum investment amount is S$100 per bid. However, in practice, the amount you receive depends on the auction demand and allotment. If there is high demand, you may not receive the full amount you requested.

4. Can foreigners buy Singapore T-bills?

Foreigners who are Singapore permanent residents or who hold valid work passes and reside in Singapore can invest in T-bills. You will need a CDP account and a Singapore bank account. Foreigners visiting Singapore on short-term passes are generally not eligible.

5. What is the difference between a competitive and non-competitive bid?

A competitive bid allows you to specify the yield you want. You will only be allocated T-bills if the final cut-off yield meets or exceeds your requested rate. A non-competitive bid does not specify a yield – you accept whatever the average yield is. Non-competitive bids are guaranteed to be filled (up to a certain limit), making them ideal for most retail investors.

6. Do I pay tax on T-bill interest in Singapore?

No, interest earned on T-bills is exempt from personal income tax in Singapore. This is one of the key advantages of T-bills compared to other interest-bearing instruments, though Singapore does not tax personal interest income in general.

7. Can I use T-bills as collateral for a loan?

Yes, in some cases, T-bills held in a CDP account can be used as collateral for margin trading or certain types of loans. However, policies vary by bank and financial institution. Check with your bank for specific details on T-bill collateral arrangements.

8. What happens if I need my money before the T-bill matures?

T-bills are not redeemable before maturity. If you need your funds early, you would need to sell the T-bill on the secondary market through a licensed broker. Selling before maturity may result in a loss or gain depending on prevailing market interest rates. This is why it is important to invest only money you will not need during the tenor.
