T-Bill Singapore 2026: Complete Guide

Current Rates, How to Apply, and Q4 2026 Outlook

Singapore T-bills (Treasury Bills) are short-term government securities issued by the Monetary Authority of Singapore (MAS). The latest 6-month T-bill (BS26118E) cut off at 1.70% per annum at the September 10, 2026 auction — the highest yield of 2026 so far. Yields have recovered from a 2026 low of 1.46% in early July. This guide covers everything you need: current rates, how to apply via cash, CPF or SRS, and what to expect in Q4 2026.

What Is a T-Bill in Singapore?

A Treasury Bill (T-bill) is a short-term debt instrument issued by the Singapore Government. When you buy one, you are essentially lending money to the government. In return, the government pays you back the full face value at maturity — plus the yield earned.

Singapore T-bills are available in two tenors:

T-bills are issued at a discount to face value. If the cut-off yield is 1.70% and you invest S$10,000 in a 6-month T-bill, you receive approximately S$10,085 at maturity (S$85 in interest). The returns are fully exempt from income tax for Singapore residents.

T-bills are considered one of the safest investments available in Singapore. They are backed by the full faith of the Singapore Government and carry essentially zero credit risk. You can check out our Singapore T-bills 2026 guide for a deeper look at the mechanics.

Singapore T-Bill Rates 2026: The Full Year Story

This year has been a dramatic one for T-bill yields. Singapore T-bills started 2026 above 3%, riding the high interest rate environment that persisted from 2024 and 2025. But as the US Federal Reserve cut rates through H1 2026, MAS monetary policy eased alongside it — and T-bill yields fell sharply.

The low point came at the July 10, 2026 auction, where the 6-month cut-off yield hit just 1.46%. Since then, yields have been recovering. The September 10 auction printed 1.70% — the highest of 2026 — as inflation ticked up slightly and bond markets repriced rate cut expectations for Q4.

How to Apply for a Singapore T-Bill in 2026

There are three ways to apply for a T-bill in Singapore: via cash through your bank, via your CPF Ordinary Account (CPF-OA), or via your Supplementary Retirement Scheme (SRS) account. Here is how each works.

Option 1: Apply via Cash (ATM or Internet Banking)

This is the most straightforward method. You apply through your bank’s ATM or internet banking portal. The following banks support T-bill applications:

• DBS/POSB: ATM (select “More” → “Invest” → “SGS” → “T-Bills”) or digibank online
• OCBC: ATM or OCBC Online Banking → “Invest” → “SGS Bonds & T-Bills”
• UOB: UOB Personal Internet Banking → “Wealth” → “Unit Trusts & Bonds” → “SGS”

Funds are deducted from your linked bank account at the time of auction and returned to your account if your bid is not successful (or partially filled).

Option 2: Apply via CPF Ordinary Account (CPF-OA)

You can use your CPF Ordinary Account funds to buy T-bills. The current CPF-OA interest rate is 2.50% per annum. At a T-bill yield of 1.70%, the T-bill actually earns less than the guaranteed CPF-OA rate right now.

This means using CPF-OA for T-bills in September 2026 is not recommended. You would be giving up 2.50% CPF-OA returns for 1.70% T-bill returns. The math only works in your favour if T-bill yields rise above 2.50%.

If you are still interested, apply through your DBS/POSB ATM (select “CPF Investments”) or OCBC. Your CPF Board account must be linked to a bank account.

Option 3: Apply via SRS Account

Your Supplementary Retirement Scheme (SRS) account can also be used to invest in T-bills. SRS contributions earn just 0.05% in cash by default, so even the current 1.70% T-bill yield is a significant improvement.

SRS T-bill applications are made through your SRS operator bank: DBS, OCBC, or UOB. This is one of the most tax-efficient uses of SRS funds if you prefer capital preservation over growth. For growth-focused SRS investing, you might consider platforms like Endowus (referral code: 2V343), which offers diversified portfolios for SRS money.

Competitive vs Non-Competitive Bids

When applying, you choose between two bid types:

Recommendation: Use a non-competitive bid if you just want to earn whatever the market rate is. The risk of getting a zero allotment on a competitive bid is not worth it for most investors.

T-Bill vs SSB vs Fixed Deposit 2026: Which Pays More?

With T-bill yields well below their 2024-2025 highs, it is worth comparing your options. Here is how the main risk-free alternatives stack up in September 2026:

Key finding: The 6-month T-bill at 1.70% is competitive with 6-month fixed deposits. However, CPF-OA at 2.50% and some bank savings accounts with bonus rates can outperform T-bills without the auction complexity. The SSB wins for anyone with a 3–10 year horizon, offering 2.32% average over 10 years with full flexibility to redeem.

Should You Apply for a T-Bill in Q4 2026?

Whether to buy a T-bill depends entirely on what you are trying to achieve. Here is a quick decision guide for Q4 2026:

Rate outlook: T-bill yields have been rising since the July 2026 low. If the Fed keeps rates steady (or cuts more slowly than expected), Singapore T-bill yields could continue moving upward into Q4. The September 24, 2026 auction — just one day away — will be a key signal to watch.

You can set up a standing instruction with DBS/POSB to auto-apply for each T-bill auction using your savings account. This is known as T-bill laddering — a strategy where you invest in each auction automatically, so that a portion of your portfolio matures every 6 months.
