There are no coupon payments for T-bills.

Instead, T-bills are issued at a discount to the face (par) value. Face/par value refers to S$100 in principal amount of the T-bills applied for. The discount rate of the T-bills is the cut-off yield at the auction. The interest is paid at maturity and is the difference between the purchase price and the face value. 

Non-competitive Application

• In a non-competitive application, you only specify the amount you want to invest and not the yield. You may wish to choose this option if you wish to invest in the bond regardless of the return or are unsure of what yield to bid.
• Do note that in an auction, non-competitive applications will be allotted first, up to 40% of the total issuance amount. If the amount of non-competitive applications exceeds 40%, the T-bills will be allotted to you on a pro-rated basis.
• You will get the T-bills at the cut-off yield, which is the highest accepted yield of successful competitive applications.

Note: Submitting multiple non-competitive applications does not increase the chance of successful allotment. Allotment takes into account the aggregate total amount applied by each investor, and not the number of applications submitted by each investor.

Competitive Application

• If you wish to invest in the T-bills only if it yields above a certain level, you can submit a competitive application.
• In the application, you can specify the minimum yield you are willing to accept in percentage terms, up to 2 decimal places. Please be mindful not to submit in price terms.
• Please note that you may not get the full amount that you applied for, depending on how your application compares to the cut-off yield.
  

Note: A lower yield represents a more competitive application, as you are indicating that you will accept a lower interest rate. You can submit multiple competitive applications.

The sum of the competitive and non-competitive applications that may be allotted to an individual is capped at 15% of the issuance size of the T-bills auction.

In addition, the non-competitive application per individual is capped at S$1 million per T-bills auction. Please note that final allotment could be less than S$1 million per T-bills auction, if the total amount of non-competitive applications exceeds 40%, which will result in the T-bills being allotted to non-competitive applications on a pro-rated basis.

T-bills are issued at a discount to the face value.

The cut-off yield at an auction determines the cut-off price of the T-bills, based on the formula below:
D = M/365 X R
P = S$100 – D

Where:
D = full discount per S$100 face value
M = days to maturity
R = annual rate of discount (yield), expressed as %
P = dollar price per S$100 face value

For example, if the cut-off yield for a 6-month T-bills with 182 days to maturity is 4.00%, this translates to a cut-off price of S$98.005 (rounded to 3 decimal places) per S$100 in face value. This means that for every S$1,000 of T-bills that was allotted to you, your initial investment amount would be S$980.05.

For cash applications, funds will be deducted at the point of application. The discount to the face value of your allotted T-bills will be credited into your account within 1 – 3 business days after auction date.

For SRS applications, funds will be earmarked at the point of application, for subsequent deduction within 1 – 3 business days after auction date.

For CPFIS applications, funds will be deducted within 1 – 3 business days after auction date. For more information on how to invest using CPFIS, you may visit CPF website .

Note: Please check with your bank on the relevant transaction charges (if applicable) for using the different funds for application.

There are a few possible reasons why your application was unsuccessful. Some common reasons include:

• Joint CDP accounts cannot be used to buy T-bills. You will need to have an individual CDP Securities account as a holding account to deposit your allotted T-bills.
• Invalid or incorrect CDP account number entered during the application.
• The CDP account used does not have Direct Crediting Service activated.

In addition, please note that there is an allotment limit of S$1 million per individual per T-bills auction for non-competitive applications.

You may wish to check with your bank for the exact reason(s) why your application was rejected. 

T-bills are issued via a uniform-price auction. This means that all successful applications, whether non-competitive or competitive, will be allotted the T-bills at a uniform yield, which is the cut-off yield. The cut-off yield of the T-bills auction is the highest accepted yield of successful competitive applications submitted at the auction.

In a T-bills auction, allotment starts with the non-competitive applications, followed by the competitive applications:

• Non-competitive applications are allotted first, up to 40% of the total issuance amount. If the total amount of non-competitive applications exceeds 40%, the T-bills will be allotted to non-competitive applications on a pro-rated basis. However, to ensure that the final allotments are in denominations of S$1,000, adjustments will be made by the system on a randomised basis.
• The rest of the issuance amount will be awarded to competitive applications, starting from the lowest to the highest yields submitted.

Illustration

Here is a stylised example to illustrate the allotment process for T-bills, which assumes:

Total Issuance Size of T-bills	S$20,000
Total Non-competitive Applications Received	S$8,000
Total Competitive ApplicationsReceived	S$18,000

 

For this example, the allotment will be as follows:

• The non-competitive applications will be allotted first. As the non-competitive applications of S$8,000 is within 40% of the issuance size (i.e. S$8,000), the non-competitive applications will be fully allotted. This means that everyone who submitted a non-competitive application will be allotted the amount that they had bid for, capped at S$1 million per T-bills auction.
• The competitive applications will be allotted next based on the remaining auction amount of S$12,000. The applications will be allotted starting with the lowest yield, and move to the next lowest yield and so on until the remaining auction amount of S$12,000 is reached.

Competitive or Non-competitive	Application amount	Allotment amount	Cumulative allotment amount	Remarks
Non-competitive applications (A)	S$1,000	S$1,000 (fully allotted)	S$1,000
Non-competitive applications (B)	S$3,000	S$3,000 (fully allotted)	S$4,000
Non-competitive applications (C)	S$4,000	S$4,000 (fully allotted)	S$8,000
Total of Non-competitive applications	S$8,000	S$8,000 (100% of non-competitive applications allotted)	S$8,000	In this example, the non-competitive applications were 100% allotted as the total amount of non-competitive applications was within 40% of the total issuance amount.
Competitive applications at 1%	S$3,000	S$3,000 (fully allotted)	S$11,000	All applications at this yield were fully allotted as it is below the cut-off yield.
Competitive applications at 2%	S$4,000	S$4,000 (fully allotted)	S$15,000	All applications at this yield were fully allotted as it is below the cut-off yield.
Competitive applications at 3%	S$4,000	S$4,000 (fully allotted)	S$19,000	All applications at this yield were fully allotted as it is below the cut-off yield.
Competitive applications at 4%	S$5,000	S$1,000 (pro-rated allotment)	S$20,000	Applications at 4% are pro-rated as the total issuance size has been reached. 4% becomes the cut-off yield for this auction. Approximately 20% of competitive applications at this cut-off yield were allotted.
Competitive applications at 5%	S$2,000	-	-	Applications at this yield were not allotted as the total issuance size has been met.
Total of Competitive applications	S$18,000	S$12,000	S$20,000	4% becomes the cut-off yield for this auction.
In summary
Total of both Non-competitive and Competitive applications	S$26,000 (Non-competitive S$8,000, Competitive S$18,000)	S$20,000 (Non-competitive S$8,000, Competitive S$12,000)	S$20,000	Cut-off yield = 4%.

In this example, the cut-off yield is 4%. All allotted applications, non-competitive and competitive, will receive the same cut-off yield of 4%.

In a uniform-price auction, successful non-competitive and competitive applications will be allotted the T-bills at the Cut-off Yield and Cut-off Price. The Cut-off Yield refers to the highest accepted yield of successful competitive applications, and the Cut-off Price refers to the price corresponding to the Cut-off Yield. See question on "How do I compute my initial investment amount for my T-bills based on the cut-off yield?" for the formula to compute the cut-off price.

If you have placed a non-competitive application, you may refer to the % of Non-Competitive Applications Allotted for the percentage of allotment given to non-competitive applications for the auction. If you have placed a competitive application at the Cut-off Yield, you may refer to the % of Competitive Applications at Cut-off Allotted for the percentage of allotment given to applicants who bid exactly at the cut-off yield for the auction.

Do note that in the event of over-subscription, individual allotments will be adjusted on a randomised basis to ensure that allotments are in denomination of S$1,000.

For more information on the competitive bidding behaviour in an auction, you may also refer to the Median Yield and Average Yield. The Median Yield refers to the yield corresponding to the median of successful competitive applications, while the Average Yield refers to the sum product of the amount of successful competitive applications and the respective application yields, divided by the total amount of successful competitive applications. The results for each T-bills issue may differ depending on investors’ bidding behaviour.

For individual investors, if your application for the T-bills was successful, the T-bills holding will be reflected in your respective accounts after the issuance date.

• For cash applications: You can check your CDP notification statement via CDP Internet  after 6pm on issuance date. If you have opted for paper statements from CDP, the statements are typically mailed to investors from the 4^th business day of each month. Please note that every 10 units on the CDP statement represents S$1,000 in face value of your T-bills holdings. For questions on your CDP account or CDP statement, please contact CDP at 6535 7511.
• For SRS applications: You can check the statements from your SRS Operator (DBS/POSB, OCBC and UOB are SRS operators).
• For CPFIS-OA applications: You can check the CPFIS statement sent by your agent bank (DBS/POSB, OCBC and UOB are CPFIS agent banks).
• For CPFIS-SA applications: You can check your CPF statement.

This can happen if there is an over-subscription for non-competitive applications (i.e. the total amount of non-competitive applications exceeds 40% of the issuance size). In this situation, the allotment to non-competitive applications will be pro-rated, with individual allotments adjusted on a randomised basis such that allotments are in denomination of S$1,000.

This may also happen if you have made a competitive application at the cut-off yield.

Illustration
Suppose a T-bills auction receives a total of S$15,000 in non-competitive applications for a total issuance size of S$30,000.

As the non-competitive applications of S$15,000 exceeds 40% of the issuance size (i.e. S$12,000), the allotment to non-competitive applications will be pro-rated by approximately 80% (S$12,000/S$15,000). This means that everyone who submitted a non-competitive application will have their allotments pro-rated and adjusted on a randomised basis to ensure that allotments are in denomination of S$1,000.

Competitive or Non-competitive	Application amount	Allotment amount	Cumulative allotment amount
Non-competitive application (A)	S$1,000	S$0 (not allotted)	S$0
Non-competitive application (B)	S$2,000	S$1,000 (partially allotted)	S$1,000
Non-competitive application (C)	S$3,000	S$3,000 (fully allotted)	S$4,000
Non-competitive application (D)	S$4,000	S$4,000 (fully allotted)	S$8,000
Non-competitive application (D)	S$5,000	S$4,000 (partially allotted)	S$12,000
Total of Non-competitive applications	S$15,000	S$12,000 (Approximately 80% of non-competitive applications allotted)	Applications are pro-rated by approximately 80%, with individual allotments adjusted on randomised basis to ensure that allotments are in denominations of S$1,000.

For cash applications: You will receive a combined refund on the (i) non-allotted amount, and (ii) discount on the face value of T-bills which you have been allotted.

Using a 6-month T-bills with a cut-off yield of 4.00% and cut-off price of S$98.005 (rounded to 3 decimal places) per S$100 in face value as an example. If you have submitted a non-competitive application of S$2,000, and was only allotted S$1,000, you will receive a combined refund of (i) S$1,000 of your non-allotted amount, and (ii) discount on the face value of T-bills, which would be S$19.95.

Note: The discount rate of the T-bills is the cut-off yield at the auction.

For CPFIS and SRS applications: Only the settlement amount (allotted amount net of the discount) will be deducted from your respective accounts.

Using the same example above, if you submitted a non-competitive application of S$2,000 and was only allotted S$1,000, only the settlement amount of S$980.05 will be deducted from your account. 

No, you are not able to redeem your T-bills prior to maturity.

However, you can sell your T-bills in the secondary market through DBS, OCBC or UOB by visiting their branches. You should indicate whether you are using cash, SRS or CPFIS funds. Please note that prices in the secondary market may change day-to-day according to market conditions, and may be higher or lower than what you had paid for.

On maturity, the principal amount will be credited to your respective account by the end of the day, typically after 6pm.

• For cash applications: The principal amount will be credited to your designated Direct Crediting Service bank account. If you cannot remember which bank account is linked to your CDP account, you can check using the CDP internet service or refer to the header section in your monthly CDP account statement to find out.
• For SRS applications: The principal amount will be credited to your SRS account.
• For CPFIS-OA applications: The principal amount will be credited to your CPF Investment Account.
• For CPFIS-SA applications: The principal amount will be credited to your CPF SA account.

Please note that should the maturity date fall on a day when MAS’ electronic payment system is not in operation, the transaction will take place on the next business day.
