Singapore T-Bills Investment Guide 2026: How to Buy Treasury Bills

Last updated: July 2026 | SeaMoneyTips

Singapore T-bills (Treasury bills) are among the safest short-term investments available to retail investors in Singapore. Issued by the Monetary Authority of Singapore (MAS) on behalf of the Singapore Government, these instruments offer a low-risk way to park surplus cash while earning competitive yields. In this Singapore T-bills investment guide for 2026, we explain what they are, how MAS auctions work, how to buy them via ATM or internet banking, current yields, the T-bill vs SSB comparison, tax treatment, and pros and cons. If you want a capital-guaranteed alternative to fixed deposits, T-bills deserve a spot in your portfolio.

Whether you are a beginner exploring how to start investing in Singapore or an experienced investor looking for a safe haven during volatile markets, Singapore Treasury bills give you government-backed returns with maturities of six months or one year. This guide walks you through every step.

What Are Singapore T-Bills?

Singapore T-bills are short-term debt instruments issued by the Singapore Government through the MAS. They are sold at a discount to face value and redeemed at full face value at maturity, with the difference representing your return. For example, if you buy a $1,000 T-bill at $970, you receive $1,000 at maturity, earning $30 over the tenor.

Two tenors are currently offered:

6 month T-bill Singapore – the most popular tenor, auctioned roughly every two weeks.
1 year T-bill – auctioned quarterly, suited to investors who want a slightly longer lock-in for marginally higher yields.

T-bills are backed by the full faith and credit of the Singapore Government, which holds the highest sovereign credit rating (AAA) from all three major rating agencies. This makes them one of the safest investments available anywhere. You can learn more about the official issuance calendar on the SGS website.

How MAS T-Bill Auctions Work

Singapore Treasury bills are sold through regular auctions conducted by MAS. The auction process determines both the cutoff yield and the allocation for each bid. Understanding the two bidding methods is essential before you participate.

Non-Competitive Bidding

Non-competitive bidding is the simplest method and is recommended for most retail investors. You specify only the amount you want to invest (minimum $1,000, in multiples of $1,000) without stating a desired yield. You are guaranteed an allocation at the cutoff yield determined by the auction, subject to availability. Non-competitive bids are limited to $1 million per auction.

Competitive Bidding

Competitive bidding requires you to specify both the amount and the yield you are willing to accept. Bids are filled from lowest yield (highest price) to highest yield until the issuance amount is exhausted. If your stated yield is above the cutoff, your bid is rejected entirely. This method is favoured by institutions and sophisticated investors who want to lock in a specific return.

The cutoff yield – also known as the t-bill yield Singapore rate that headlines the news – is the highest accepted yield at each t-bill auction Singapore event. Full auction results, including the cutoff yield, competitive and non-competitive allocation amounts, and bid-to-cover ratio, are published on the SGS auction results page shortly after each auction closes.

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

Buying Singapore T-bills is straightforward once you have a Central Depository (CDP) account linked to your bank. Here is the step-by-step process to buy via ATM or internet banking.

Open a CDP account. If you do not already have one, apply through the CDP website or via your brokerage. Your CDP account is where your T-bills will be held.
Link your CDP account to your bank. Most major banks in Singapore (DBS/POSB, OCBC, UOB) allow you to link your CDP account through their internet banking portal.
Check the auction calendar. Visit sgs.gov.sg for upcoming SGS T-bill auction dates. The MAS publishes a quarterly calendar with auction dates and tenors.
Place your bid. Log in to your bank’s ATM or internet banking platform. Navigate to the ‘Singapore Government Securities’ or ‘Bonds and SGS’ section, select the upcoming SGS T-bill auction, choose non-competitive or competitive bidding, enter the amount (minimum $1,000), and confirm.
Wait for auction results. Auctions typically close on a specified afternoon. Results are published the same day or the next business day. If you used non-competitive bidding and your bid was within limits, you will receive a full allocation.
Check your CDP statement. Allotted T-bills are credited to your CDP account. You can verify your holdings through the CDP online portal or your bank’s investment section.
Receive payment at maturity. At maturity, the face value is credited to the bank account linked to your CDP. No action is required from you.

For investors comparing T-bills with longer-term government instruments, our Singapore Savings Bonds (SSB) guide explains how SSBs differ in tenor, liquidity, and yield structure.

Current Singapore T-Bill Yields (2026)

T-bill yields in Singapore track closely with market interest rates and the Singapore Overnight Rate Average (SORA). In 2026, the 6 month T-bill Singapore yield has generally traded in the range of 3.0% to 3.6% per annum, while the 1 year T-bill has offered a small premium above the 6 month tenor. Yields fluctuate with each auction based on demand, global rate expectations, and liquidity in the banking system.

Because yields are determined by the market rather than fixed in advance, the t-bill yield Singapore investors earn can vary from one auction to the next. Always check the most recent auction results before placing your bid to set realistic expectations.

T-Bill vs SSB: Which Is Better?

Both Singapore T-bills and Singapore Savings Bonds are government-backed, but they suit different investor needs. The t-bill vs ssb comparison below highlights the key differences.

Feature	Singapore T-Bills	Singapore Savings Bonds
Issuer	Singapore Government (MAS)	Singapore Government (MAS)
Tenor	6 months or 1 year	Up to 10 years
Minimum investment	$1,000	$500
Interest payment	Discount at purchase, paid at maturity	Semi-annual coupons
Early redemption	No – held to maturity	Yes, any month with no penalty
Liquidity	Locked until maturity	Monthly exit option
Yield structure	Fixed per auction	Stepping up over time
Best for	Short-term cash parking	Long-term flexible savings

In short, choose T-bills when you have a defined short horizon and can lock your funds for 6 or 12 months. Choose SSBs when you want flexibility and the option to redeem without penalty. Many investors hold both to balance liquidity and yield.

Tax Treatment of Singapore T-Bills

Profits from Singapore T-bills are exempt from income tax for individual investors. This means the full discount you earn at maturity is yours to keep, with no tax deducted. This tax exemption applies to Singapore citizens, permanent residents, and non-residents alike, provided the investment is held in a personal CDP account.

This favourable treatment makes T-bills especially attractive compared to taxable alternatives. For context, our guide to structured deposits vs fixed deposits in Singapore explains how other instruments handle tax and capital guarantees differently.
