How do you learn Treasury bills quickly and correctly? Begin with the idea of paying less today to receive a stated face value at maturity. A Treasury bill, commonly called a T-bill, is a short-term government debt security. Singapore Government Securities T-bills are issued by the Singapore Government, normally with six-month or one-year maturities. Instead of paying regular coupons, they are issued at a discount to face value and pay that face value at maturity under their terms. This eduKateSG Finance Quick Notes lesson explains the difference between what you pay, what you receive and what happens if you need to sell before maturity.
- Issuer: the Singapore Government for Singapore Government Securities T-bills.
- Tenor: the length of time until maturity; Singapore T-bills are typically six months or one year.
- No coupon: T-bills do not provide periodic coupon payments.
- Discount: you pay less than the face value under the relevant issue pricing.
- Maturity: under the security terms, the stated face value is paid at maturity.
- Auction: investors apply under competitive or non-competitive bidding rules.
- Liquidity: an early sale has market-price risk, so T-bills are not identical to on-demand cash.
Teaching paragraph 1 — distinguish the face value from the purchase price. Imagine a six-month government T-bill with a face value of S$1,000. Suppose for classroom illustration the discount purchase price is S$990. If you hold it until maturity and receive the S$1,000 face value, the difference is S$10 before any relevant transaction costs or adjustments. There is no separate semiannual coupon in this example. The return comes from the difference between the price paid and the amount received at maturity. This is a hypothetical price, not an actual Singapore auction outcome or a promised yield.
Teaching paragraph 2 — calculate the holding-period return. Use (maturity amount − purchase price) ÷ purchase price × 100. Here the numerator is S$1,000 − S$990 = S$10; dividing S$10 by S$990 gives about 1.01% over the whole holding period. If the term is approximately six months, that is not the same as a 1.01% annual yield. Official auction yields follow specified market conventions and exact dates, so do not casually double a half-year figure and label it the official cut-off yield. For beginners, understand the cash difference first, then learn the appropriate annualised convention.
Teaching paragraph 3 — understand why a sale before maturity is different. Suppose a person holds a T-bill that would pay S$1,000 at maturity, but urgently needs money before then. They may seek to sell it on the secondary market. The price available at that moment depends on market conditions, including interest rates, time remaining and demand. They might receive less than expected, and the instrument may not be as convenient to sell as withdrawing money from an ordinary bank account. The stated maturity value does not promise you a particular selling price tomorrow. Before buying, check whether the term matches when you will need the cash.
The One-Line Treasury Bill Formula
Simple holding-period gain = amount paid at maturity − purchase price. With a fictional S$1,000 face value and S$990 purchase price, the simple gain at maturity is S$10. The corresponding simple holding-period rate is S$10 ÷ S$990 × 100 ≈ 1.01%. This rate excludes any fees or unusual terms and is not an official auction yield or annualised return.
Your First S$1,000 T-bill Example
- Fictional T-bill face value: S$1,000.
- Illustrative term: six months.
- Hypothetical discount purchase price: S$990.
- Periodic coupon: none.
- Amount paid at maturity under the terms: S$1,000.
- Simple difference: S$10.
- Simple holding-period return: approximately 1.01%, before any applicable costs.
The example is deliberately small so you can see how discounting works. Real primary-market issues are allotted through auctions, with prices and yields determined by the actual auction outcome. Use the Monetary Authority of Singapore’s official information to check current issuance details rather than a fixed rate printed in an old study note.
How T-bills Differ from Coupon Bonds
A conventional coupon bond may pay stated interest periodically and repay principal at maturity. A Singapore T-bill has no coupon, so an investor normally obtains the return by buying at a discount and receiving face value at maturity. Both are debt instruments, yet their tenor, payment structure and market risks can differ. Some longer-term government bonds pay interest every six months, while T-bills do not. See How to Learn Bonds Quickly and Correctly for the conventional bond model.
How Long Do Singapore T-bills Last?
The Monetary Authority of Singapore lists Singapore Government Securities T-bills with six-month and one-year tenors. The exact issue dates, auctions and maturity dates are given in the official calendar and security details. A six-month T-bill is not guaranteed to mature on the same day of the month after exactly 180 days; use its actual issue and maturity dates. Choosing a term is partly a cash-flow decision: if you need the money in three months, a six-month maturity may not match that need.
What Is an Auction?
In a T-bill auction, eligible investors submit bids through prescribed channels. A competitive bid specifies a yield the investor is willing to accept; a non-competitive bid does not specify a yield and accepts the cut-off yield if allotted under the auction rules. The cut-off yield is determined by the auction, and allocations are subject to the relevant limits and procedures. Non-competitive does not mean guaranteed allotment in every circumstance. Learn the difference before treating an application as a confirmed purchase.
How Much Can an Individual Apply For?
As described by MAS, individuals can generally apply for Singapore T-bills from S$1,000 face value and in multiples of S$1,000. Current application methods, account requirements and auction limits depend on the official rules and participating banks. Cash, Supplementary Retirement Scheme funds or CPF Investment Scheme funds may be eligible, subject to the relevant account rules. Do not assume funds from each source carry the same opportunity costs or accessibility restrictions.
What Does ‘No Coupon’ Mean?
A zero-coupon-style T-bill does not send periodic interest payments into your bank account while you hold it. Instead, the return built into its purchase and maturity values is realised according to the instrument’s payment structure. It is therefore unsuitable to describe it as a product that pays you a fixed monthly salary. If you want money available each month, the schedule of actual receipts must be examined, not imagined.
Why an Advertised Yield Is Not a Cash Payment
A yield is a rate for comparing returns under defined assumptions; it is not automatically the amount credited to your account. A T-bill’s purchase price, face value, exact dates and market yield are related through established pricing conventions. The first correct question is ‘How much do I pay and what is due at maturity?’ The second is ‘How is that return annualised?’ Do not multiply an official percentage by the full face value for an arbitrary number of months without checking the calculation method.
T-bills Versus Singapore Savings Bonds
Both Singapore T-bills and Singapore Savings Bonds are backed by the Singapore Government, but their structures differ. A T-bill normally matures in six months or one year and has no coupon. A Singapore Savings Bond has a longer maximum tenor and permits redemption in specified monthly windows under its own conditions. Savings Bonds can be more flexible when a person may need the principal back before the final maturity date, whereas a T-bill holder needing cash early may have to sell at a market price. Check fees and account rules too.
T-bills Versus Savings Accounts
Money in a suitable bank deposit account may be withdrawable according to its account conditions, while a T-bill has an established maturity and separate secondary-market mechanics. The products can also differ in applicable deposit protection and interest or yield arrangements. A government-backed debt obligation should not automatically be described as the same thing as a bank deposit. For emergency savings, accessibility and timing deserve attention alongside a yield comparison.
What Can Affect a T-bill Sold Early?
- Changes in market interest rates and prevailing yields.
- How much time remains until maturity.
- Market demand and available buyers.
- Costs or spreads involved in a secondary-market sale.
- The investor’s particular account and transaction arrangements.
The Singapore Government’s backing supports the contractual obligation at maturity, but secondary-market prices may still move. An investor who has to sell early can experience a different outcome from someone who holds to maturity. If you cannot afford a price change or a delay in receiving funds, assess the product’s liquidity carefully.
The Beginner’s Checklist Before Applying
- Find the issuer and exact security type.
- Check the auction, issue and maturity dates.
- Understand whether the bid is competitive or non-competitive.
- Confirm the face amount, minimum application and funding source.
- Check how the auction’s yield and purchase price are determined.
- Know how the maturity proceeds will be credited.
- Confirm what happens if you need to sell before maturity.
Common T-bill Mistakes
- Thinking a T-bill pays a monthly coupon.
- Confusing face value with the amount paid at auction.
- Treating a half-year holding-period percentage as the official annual auction yield.
- Assuming a non-competitive bid is an unconditional guarantee of allotment.
- Believing maturity value and early-sale price must be identical.
- Treating T-bills as unrestricted on-demand emergency cash.
- Using outdated auction data to predict a future issue’s yield.
