Introduction to SGS Bonds and T-bills

1. What Are Singapore Government Securities (SGS) Bonds and T-bills?

Singapore Government Securities (SGS) bonds and Treasury bills (T-bills) are marketable debt instruments of the Government of Singapore. These debt instruments are backed by the full credit of the Singapore Government. The terms of issuance for T-bills and bonds are governed by the Local Treasury Bills Act and the Government Securities Act respectively.

The Singapore Government is obliged to pay the holders of SGS bonds and T-bills a fixed sum of money on the maturity date of the securities. SGS bonds and T-bills cannot be cashed in before their maturity dates, but investors can always sell them in the secondary market. SGS Primary Dealers are prepared to buy and sell SGS bonds and T-bills at any time during normal market trading hours.

As the fiscal agent of the Government, the Monetary Authority of Singapore (MAS) undertakes the issuance and management of SGS on its behalf

2. What Are The Types Of SGS?

T-bills are short-term debt securities that mature in one year or less from their issue date. They are bought and sold at a discount, i.e. at a price less than their face (par) value, and when they mature, the Government will pay the holder an amount of S$ equivalent to the face value of the security. Therefore, the interest earned on the T-bill is the difference between its purchase price and face (par) value. They are denominated at nominal values of S$1,000 and traded at a rate of discount basis. The Government currently offers only 1-year T-bills.

SGS bonds are longer-term debt securities, which pay a fixed rate of interest (called the coupon) every six months for the life of the securities and then their face (par) values upon redemption on maturity. They are  not issued at a discount unlike T-bills, and have typical maturities of 2, 5, 10, 15, 20 and 30 years.

Singapore Savings Bonds are non-marketable debt securities. For more information on Singapore Savings Bonds, please click here.

3. Why does the Singapore Government issue SGS?
Unlike many other countries, the Singapore Government does not need to finance its expenditures through the issuance of government bonds as it operates a balanced budget policy and often enjoys budget surpluses.

Singapore Government Securities (SGS) were initially issued to meet banks' needs for a risk-free asset in their liquid asset portfolios. Following efforts to enhance the efficiency and liquidity of the SGS market by MAS in 1998 as part of its strategy to develop Singapore as an international debt hub, the market has since grown significantly, making it one of the fastest developing bond markets in Asia. Currently, SGS bonds and T-bills are issued primarily to:

  • Build a liquid SGS market to provide a robust government yield curve for the pricing of private debt securities;
  • Foster the growth of an active secondary market, both for cash transactions and derivatives, to enable efficient risk management; and
  • Encourage issuers and investors, both domestic and international, to participate in the Singapore bond market.

Singapore Savings Bonds are issued to individuals to provide them with a long-term savings instrument.

Proceeds from SGS issuance are instead paid into a Government Securities Fund, from which any interest and principal repayments on the SGS are withdrawn. A document summarising the details of the Singapore Government's borrowing portfolio and its unique nature can also be accessed here.

4. Are SGS investments considered safe?
The long-term local and foreign currency debt ratings of the Singapore Government accorded by the various international credit rating agencies are listed below:







 Local Currency





 Foreign Currency






These international credit rating agencies assess a country's ability to meet financial commitments, such as interest payments or repayment of principal, on a timely basis. Singapore's consistent ratings indicate that it has a very strong credit rating with a minimal probability of default on its local currency debt obligations. From the perspective of individual investors, this means that SGS are among the safest possible investments to hold, and the principal value of their SGS investments is preserved if held to maturity. Individual investors should note that SGS bonds and T-bills sold before maturity will be at prevailing market prices that can be higher or lower than the purchase price.

5. When Are SGS Issued?
SGS are issued according to an issuance calendar published at the end of the preceding calendar year.

The issuance calendar contains the list of bonds that will be issued throughout the year and the key dates associated with each bond issuance. The amount of bond that will be issued will be announced one week prior to the auction. The calendar also includes the possible mini-auction dates for the year.

6. How Are SGS Bonds and T-bills Issued?
SGS bonds/T-bills are issued via uniform-price auctions.

This means that successful bids (whether competitive or non-competitive) are allotted at the same yield, which is the highest accepted yield (cut-off yield) of bids received at the auction.

7. What Role Do Primary Dealer Banks Play In An SGS Bonds and T-bills Auction?
Primary Dealers are appointed to act as specialist intermediaries in the SGS and S$ money markets. Only Primary Dealer banks can participate directly in the SGS bond and T-bill auctions. Other market participants, including individual investors, will submit bids through one of the Primary Dealers. Primary Dealers are also obliged to provide liquidity in the SGS market by quoting prices on all SGS bond and T-bill issues under all market conditions. Click here for a list of the Primary Dealers. 

8. What Is The Difference Between Competitive And Non-Competitive Bids?

Investors can choose to submit a competitive or non-competitive bid when participating in an SGS auction.

In a competitive bid, investors specify the price (expressed in terms of percentage yield) that they are willing to pay for the SGS bond/T-bill. Investors may or may not be allotted the bond, depending on whether their submitted yields are higher or lower than the cut-off yield. In the context of SGS bonds/T-bills, a lower yield represents a more competitive bid as the investor is indicating that he/she will accept a lower return.

In a non-competitive bid, the investor does not specify a price (expressed in terms of percentage yield). This indicates that he/she is willing to accept the bond at any price as determined by the auction.

In the auction, MAS will allot the non-competitive bids first before moving on to the competitive bids, starting from the lowest to highest yields. The total non-competitive allotment is limited to 40% of the issue on offer. If the amount of non-competitive bids exceeds 40%, the SGS bonds/T-bills will be allotted to the non-competitive bidders on a pro-rated basis.

9. How Are The Coupon Rates For SGS Bonds And Discount Rates For T-bills Determined During An Auction?
The coupon rate for a newly issued SGS bond, also known as the primary issuance, is the cut-off (or highest accepted) yield of successful bids submitted at the auction, rounded down to the nearest 0.125%, or 0.125%, whichever is higher. Should the coupon rate be lower (or higher) than the cut-off yield, the purchase price would be lower (or higher) than 100% of the bid amount. The difference would be credited (or debited) into/from the individual investor's bank account. For T-bills, the cut-off yield is not rounded down, and is equivalent to the discount rate.

10. What Are The Specific Features Of The Coupon Payments?

SGS bonds pay interest on a semi-annual basis. In the event that the payment date falls on a public holiday, the coupon will be paid out on the next business day.

For coupon accruals, the interest accrues from the previous coupon date (inclusive) to the settlement date (exclusive). SGS trades ex-coupon three working days prior to the coupon date.

11. What Is A Reopening Of A SGS Bond Issue? How Are Reopened SGS Bonds Different From Newly-Issued SGS Bonds?
MAS may choose to issue a new SGS bond or to reopen an existing bond as a benchmark or non-benchmark issue. Re-opening refers to issuing an additional amount of an existing bond on top of its existing outstanding size in the market. This existing bond would already be available in the secondary market and its market price would take into account capital gains and accrued interest. Only SGS bonds (not T-bills or Singapore Savings Bonds) are subject to reopening. 

The difference between newly issued and reopened SGS bonds is that even after the auction, reopened bonds retain the same maturity date and coupon that they had when they were first issued. If an existing bond is reopened as a benchmark issue, the remaining term-to-maturity of the re-opened bond will be different from that of the original benchmark bond. For instance, MAS re-opened an existing 5-year bond issue N500100X as a 2-year benchmark bond on 1 November 2002. When N500100X was first issued on 1 February 2000, it had a term-to-maturity of 5 years, but when it was re-opened as the 2-year benchmark bond on 1 November 2002, it had a remaining term-to-maturity of 2 years and 4 months. 

For reopened bonds, the amount debited at auction applications will be 115% of the bid amount to take into account capital gains and accrued interest, since the market price of the reopened bond is only known after the auction. If the purchase price of the reopened bond is lower (or higher) than 115% of the bid amount, the difference would be credited (or debited) into/from the individual investor's bank account.

Investors interested in applying for reopened SGS bonds should view this document for further details.


12. What Affects SGS Bond/T-bill Prices?
The price of a SGS bond or T-bill is what the market is willing to pay for it - it is the market's estimate of its value. While the prices of SGS bonds and T-bills ultimately reflect the balance between the forces of demand and supply, several factors underpin the market’s pricing assessment. Macroeconomic factors such as expectations of future interest rate levels and currency movements, technical pricing analysis and tactical positioning all have an influence over SGS bond and T-bill prices. SGS Bonds and T-bills that are selling at a price above their face value are said to be selling at a premium, while those with prices below face value are said to be selling at a discount.

13. Where Can I Obtain Daily And Historical SGS Bond/T-bill Prices?
SGS bond/T-bill prices are published once a day and are available from 6:00pm at this link. Published prices reflect the bid rates quoted by SGS primary dealers.

Historical SGS Bond/T-bill prices can also be found here.


Purchasing and selling SGS

14. What Is The Minimum Investment Amount For SGS Bonds/T-bills?
The minimum denomination to purchase SGS bonds/T-bills is S$1000, and you can invest in multiples of S$1000.

15. Can My CPF Funds Be Used To Buy SGS Bonds/T-bills?
Under the CPF Investment Scheme (CPF-IS), you can use the full balance in your Ordinary and Special Account savings to buy SGS bonds/T-bills. Applications using CPF funds have to be made in person at applicable bank branches. For more information about CPF-IS rules, go to http://mycpf.cpf.gov.sg/Members/home.htm.

SRS funds can be used to buy SGS bonds/T-bills. From February 2019, applications using SRS funds can be made electronically, via SRS Operators’ internet banking portals. With electronic applications, SRS Operators will no longer accept applications for SGS bonds/T-bills using SRS funds at bank branches.

17. Can Non-Residents Buy SGS?
There are no restrictions to non-residents purchasing SGS. Both Singaporeans and foreign residents can invest in SGS.

18. Are Capital Gains And Interest From SGS Taxable For Individual Investors?
Capital gains are not taxed in Singapore, and SGS interest income accrued to individual investors is currently exempt from tax. Furthermore, for all SGS issued between 28 Feb 1998 and 31 Dec 2023 (both dates inclusive), interest on SGS earned by non-residents who do not have any permanent establishments in Singapore is also tax-exempt.

19. How Do I Purchase SGS Bonds/T-bills?
You may purchase SGS bonds/T-bills either at primary auctions or in the secondary market.

i) At a Primary Auction

After the auction announcement, the most convenient way for individual investors to submit bids for SGS bonds/T-bills would be through DBS/POSB, OCBC or UOB ATMs or internet banking portals.

For cash applications, investors may submit bids through banks’ ATMs or internet banking portals. Similar to an IPO application, you will need a valid individual CDP account number. Joint CDP accounts cannot be used to bid at primary auction.

For applications using SRS funds, individual investors may submit bids through SRS Operators’ (i.e. DBS/POSB, OCBC or UOB) internet banking portals from February 2019 onwards. Please note that with the launch of electronic applications, SRS Operators will no longer accept applications for SGS/T-bills in-person at bank branches or through ATMs.

Applications using CPF funds have to be made in person at applicable bank branches. For more information about CPF-IS rules, go to http://mycpf.cpf.gov.sg/Members/home.htm.

A summary of application modes is provided in the table below.

SGS Bonds/ T-bills
  • ATM
  • Internet Banking
  • Internet Banking
  •  In person at bank branch


Applications for SGS bonds/T-bills open from 6pm on auction announcement date and close at 9pm one day before the date of auction, subject to the operating hours below.

  • 6pm to 9pm on the day of auction announcement; and
  • 7am to 9pm on Mondays to Saturdays (excluding Public Holidays).

For new bond issues, the full bid amount will be debited or earmarked from your bank account or SRS account respectively at the point of application.

For reopened bonds, the amount debited or earmarked will be 115% of the bid amount. If the purchase price of the reopened bond is lower (or higher) than 115% of the bid amount, the difference would be credited (or debited) into/from your bank account, or SRS account for applications using SRS funds. If the bank is unable to debit the difference from your bank account or SRS account, the bank is entitled to sell the bond at the prevailing market price and refund the proceeds to your bank account or SRS account.

After the auction, MAS will announce the aggregate auction results at 1 pm on the date of the bond auction. You will be able to view the results on SGS website. Successful investors will receive a statement notification from CDP (for cash applications) or their SRS Operator (for applications using SRS funds), typically within 1 week from the date of bond issuance.
For more information on SGS bonds/T-bills applications via the local banks, please refer to the table below for their contact details.

ii) In the Secondary Market

Investors can also buy or sell SGS bonds in the secondary market on the Singapore Exchange (SGX). To do so, you need to have a securities trading account at a brokerage firm and an individual CDP securities account. If you wish to invest in SGS bonds using SRS funds in the secondary market, you need to link the SRS account to the brokerage account and choose to pay for the transaction using funds from SRS accounts. Trading SGS bonds on SGX would incur transaction and brokerage costs. For more information, you may refer to http://www.sgx.com/fixedincome/sgs.

If you wish to buy or sell T-bills in the secondary market, you can approach the main branch of any of the SGS dealer banks (typically DBS, OCBC and UOB) to buy/sell your holdings at the available market price.

20. As An Individual Investor, Where Are My SGS Investments Custodised? 
If you are purchasing SGS using cash, your SGS investments will be custodised at the Central Depository (CDP). As CDP also custodises individual investors’ investments in Singapore-listed equities, investors have the convenience of a single custodian for both equity and SGS investments. It is free of charge to open a CDP account – find out more at http://www.sgx.com/wps/portal/sgxweb/home/depository.

If you are purchasing SGS using SRS funds, your SGS investments will be custodised by your respective SRS Operator (i.e. DBS/POSB, OCBC or UOB).

21. How Do I Make/Receive Payments For My SGS Transactions And Receive Interest/ Principal Payments?
For primary auction applications via the ATM or internet banking, payment will be deducted from the bank account that you use to make the application. For applications using cash, interest and principal payments on SGS will be paid to the bank account linked to your CDP account. For applications using SRS, interest and principal payments will be made into your SRS account.

For secondary market transactions, to facilitate payment/receipt of funds for the purchase/sale of SGS bonds or T-bills, you should open an account with the bank or broker that you intend to transact with.

22. Can I Sell My SGS Bonds/T-bills Before Maturity?
Yes. You can sell your SGS bonds before maturity either on the Singapore Exchange (SGX) or through one of the local banks (i.e. DBS/POSB, OCBC, or UOB).

For SGS bonds that were purchased using CPF funds or SRS funds, please ensure that your brokerage account is linked to the CPF or SRS account so that you can sell the bonds that are custodised at the CPF agent bank and SRS Operator respectively.
T-bills do not trade on the SGX. To sell T-bills before maturity, please approach one of the local banks (i.e. DBS/POSB, OCBC, or UOB).

Please note that prices of SGS bonds/T-bills vary day to day according to market conditions, you may not be able to sell your SGS bonds/T-bills for the same price that you paid for them.

23. Are There Any Fees For Custodising SGS Investments at CDP, CPF agent bank or SRS Operators?
CDP does not charge fees for custodising SGS investments.
CPF agent banks charge custody fees. Please approach the CPF agent banks for more details.
SRS Operators do not charge fees for custodising SGS investors.


Calculating returns on SGS investments

24. How Do I Calculate The Returns On My SGS Bond/T-bill Investment?
There are different measures of returns for bonds.

1) One simple way of calculating bond return is to take into account capital gains and interest received. 

If you bought a fixed rate 10-year bond paying a 4% coupon with a face value of S$100, you will receive semi-annual interest equal to (S$100 x 0.04 / 2) = S$2.00.

(i) Assume you had bought the bond at a primary auction at S$100 and sold it 1 year later.
(a) If the bond had appreciated in price to S$102,
Return = [(102-100)+4]/100 *100 = 6%

(b) If the bond had fallen in price to S$98,
Return = [(98-100)+4]/100 *100 = 2%

(ii) If the bond was a reopened bond instead of a new bond, the coupon rate would have already been set. The purpose of the auction is then to determine the yield, which would impact the amount paid up-front for the bond. If the yield turns out lower (higher) than the coupon rate, the amount paid for the bond would be higher (lower) than S$100.

Using the above 4% coupon bond, assume that it had been re-opened at a yield of 3.5%. Because the yield is lower than the coupon rate, the price paid would have to be higher, at S$105. If the bond fell in price to S$103 one year later and you sold it, Return = [(103-105)+4]/105 *100 = 1.90% 

2) The current yield of a bond relates its annual coupon interest to its market price. If the market price of a 10-year bond with a 4% coupon is S$98, its current yield would be (4 / 98 x 100%) = 4.08%, which is more than the coupon rate of 4%. Conversely, if its market price is S$102, the current yield would be (4 / 102 x 100%) = 3.92%, which is less than the coupon rate of 4%.

3) Yield-to-maturity, by far the most widely used return measure in the bond market, combines the coupon income of a bond and the capital gain or loss from holding the bond to maturity. It also considers the timing of the bond's cash flows and interest-on-interest, although it assumes that the coupon payments can be reinvested at an interest rate equal to the yield-to-maturity.

An example, assume that you bought a bond with 1-year left at a price less than the face value of the bond e.g. S$95. The coupon interest of the bond is S$4. The capital gain at maturity is (S$100-S$95) = S$5.00. Therefore9, the total gain for you is S$9.00. The bond's yield-to-maturity is (9 / 95 x 100)% = 9.47%.

Treasury bills do not have coupon payments and are issued at a discount. Therefore, the yield that you get upon the maturity of the bill is the difference between the purchase price and the maturity price. For example, if you pay S$95 for a Treasury bill with a face value of S$100 at an auction for a 1-year Treasury bill, your yield to maturity, or amount earned if you hold the bond for one year, is (S$100-S$95) / 95 x 100 = 5.26%.

25. What Is The Relationship Between Bond Prices And Bond Yields?
Bond prices and yields move in opposite directions. To illustrate this concept, let us assume that you are holding a bond of 1-year maturity that you bought at S$900. At maturity, you will receive your principal of S$1,000. Assume the bond does not pay any coupon, so your yield to maturity is 11.1% at the moment:
[S$(1,000-900) / S$900] x 100 = 11.1%.

If the bond price falls to S$850, the yield to maturity on this bond will be higher:
[S$(1,000-850) / S$850] x 100 = 17.6%

Likewise, when the bond price rises to S$950, the bond's yield to maturity will fall:
[S$(1,000-950) / S$950] x 100 = 5.3%

Intuitively, if you bought your bond when interest rates were at 4%, a rise in interest rates to 6% will mean that you will be able to sell your bond at a lower price than what you paid for it. This is because investors can buy new bonds that will give them a higher yield (i.e. 6%). The price of your bond will therefore decline. On the other hand, if interest rates fell, investors will find your bond attractive relative to new bonds with lower yields. Therefore, the price of your bond will rise.
