Singapore T-Bill Maturity Guide 2026: Reinvest, Switch to SSB or Fixed Deposit?

What every Singapore investor should do when their 6-month or 1-year T-bill matures — current rates compared, step-by-step reinvestment guide.

When your Singapore T-bill matures, the principal and interest are credited back to your bank account or CPF-OA within 2 business days. At current rates (October 2026), 6-month T-bills are yielding approximately 1.95% p.a., while Singapore Savings Bonds (SSB) offer around 2.70% for the first year — making SSB the higher-yielding option for liquid cash unless you specifically need T-bill flexibility. Here’s how to decide what to do with your proceeds.

What Happens When Your T-Bill Matures in Singapore

Singapore Government Treasury Bills (T-bills) are short-term securities issued by the Singapore Government through the Monetary Authority of Singapore (MAS). They come in two tenures: 6-month (26-week) and 1-year (52-week). When a T-bill reaches its maturity date, the process is automatic — no action is required from you.

For cash-funded T-bills (DBS/OCBC/UOB/SRS accounts): The full face value (i.e. what you applied for) is credited back to your designated bank account within 1–2 business days of the maturity date. Because T-bills are sold at a discount, the “interest” is the difference between your application amount and the face value — you receive the full face value at maturity, not your application amount plus separate interest.

For CPF-OA T-bills: The proceeds (principal + implied interest) are returned to your CPF Ordinary Account automatically on the maturity date. While your funds are invested in T-bills, the CPF-OA accrued interest of 2.5% p.a. is suspended — this is an important consideration discussed further below.

Once the proceeds are back in your account, you face a simple but important decision: roll over into another T-bill, switch to a Singapore Savings Bond, park in a fixed deposit, or invest in longer-duration assets for passive income Singapore generation.

Current T-Bill Rates vs Alternatives (October 2026)

Before deciding what to do with your maturing T-bill proceeds, it helps to compare the current yield environment across Singapore’s main short-term savings instruments. The table below summarises the key rates as at October 2026.

Should You Reinvest in Another T-Bill?

Reinvesting in another T-bill makes sense in specific circumstances. The primary advantage of T-bills over SSBs and fixed deposits is their auction-based flexibility — you can apply through DBS/OCBC/UOB, via internet banking with your CPF-OA funds, or through your SRS account. However, at current October 2026 yields, T-bills at ~1.95% are not the highest-yielding liquid option available for free cash.

Reinvest in T-bills if:

• You want a fixed 6-month window to reassess your financial plans (salary bonus incoming, BTO payment, insurance renewal, etc.)
• You are investing through CPF-OA and the T-bill cut-off yield is expected to consistently exceed 2.5% — the current CPF-OA baseline
• You prefer the simplicity and government backing of T-bills with no application admin for SSBs
• You already have your SSB allocation maxed out at the SGD 200,000 personal limit

Skip the T-bill reinvestment if:

• Current cut-off yields are below 2.5% — at this point, leaving the money in CPF-OA earns the same or more with zero opportunity cost
• You have headroom in your SSB allocation and the SSB rate significantly exceeds T-bill yields (as is currently the case)
• The money is needed within 4 weeks — T-bill applications close 1–2 weeks before the auction date

T-Bill vs Singapore Savings Bonds (SSB) 2026

The Singapore Savings Bond is issued monthly by MAS and offers step-up interest that increases year-on-year. For most retail investors in October 2026, the SSB is the better alternative when your T-bill matures — here’s why:

The key advantage SSBs have over T-bills right now: SSB 1-year average rates (~2.70%) meaningfully exceed T-bill 6-month yields (~1.95%). If you have available SSB allocation (individual limit: SGD 200,000; household limit: SGD 400,000), switching from T-bills to SSBs on maturity gives you roughly 75 basis points more return per year.

On a SGD 50,000 portfolio, that differential is approximately SGD 375 extra per year (SGD 1,350 in SSB vs SGD 975 in 6M T-bill).

The other critical advantage: SSBs can be redeemed any month with no penalty, typically with proceeds credited within 2 business days. This makes them more liquid than fixed deposits and as flexible as T-bills for practical purposes. For more on SSB mechanics, see the Singapore Savings Bonds guide.

When T-bills still win over SSBs:

• Your SSB personal limit (SGD 200,000) is fully utilised
• T-bill yields spike above SSB rates during market stress periods (this happened briefly in 2023)
• You want CPF-OA investment (SSBs cannot be purchased with CPF-OA funds — only T-bills and SGS bonds can)

T-Bill vs Fixed Deposits 2026 Comparison

Fixed deposits are the traditional alternative, but in today’s rate environment they sit below both T-bills and SSBs for most tenures. The best 12-month fixed deposit rates from major Singapore banks hover around 1.70–1.85% in October 2026 — lower than the 6-month T-bill rate of ~1.95%.

There are two scenarios where fixed deposits still make sense on T-bill maturity:

1. Promotional rates: Occasionally, banks offer short-term FD promotions (e.g. 2.5% for a 3-month tranche for new-to-bank funds) that beat T-bill yields. These typically require fresh-fund conditions. Watch for these on GoBear or bank apps.
2. Convenience: If you are not already set up for T-bill applications and don’t want to manage SSB applications, a standard FD is still better than leaving cash in a savings account earning 0.05%.

What CPF-OA T-Bill Investors Should Do

If you purchased T-bills using your CPF Ordinary Account funds, the maturity decision is slightly different. CPF-OA earns a guaranteed 2.5% p.a. — the government-mandated floor rate. This is also the hurdle rate that your T-bill investment must beat to justify the transfer.

At current T-bill yields of ~1.95% for 6-month bills, you are actually earning less than if you had left the money in CPF-OA. The math:

• SGD 50,000 in CPF-OA at 2.5% = SGD 1,250 per year
• SGD 50,000 in 6M T-bill at 1.95% = SGD 975 (annualised equivalent)
• Difference: SGD 275 less per year in T-bills

The CPF-OA T-bill strategy made strong sense in 2023 when T-bill yields exceeded 3.8%. At current 2026 yields, the optimal move when your CPF-OA T-bill matures is to not reinvest — simply let the proceeds return to CPF-OA and earn the guaranteed 2.5% until yields recover above 2.5%.

How to Reinvest Your T-Bill Proceeds Step-by-Step

Whichever option you choose, here’s how to act quickly when your T-bill proceeds land.

Option A: Buy the Next T-Bill (Cash)

1. Log into your DBS/POSB iBanking → Invest → Bonds & T-Bills → Apply for T-bill
2. Check the upcoming auction date on the MAS website (auctions are typically every 2–3 weeks)
3. Submit a competitive or non-competitive bid by the application deadline (usually 9pm on the business day before auction)
4. Results are announced the next business day; allotment credited within 2 days

Option B: Switch to Singapore Savings Bonds

1. Applications open on the 1st of each month and close around the 26th
2. Apply via DBS/OCBC/UOB iBanking → Investments → Singapore Savings Bonds
3. Minimum application: SGD 500; increments of SGD 500; maximum SGD 200,000 per person
4. Interest is paid every 6 months directly to your bank account

Option C: Open a Fixed Deposit

1. Compare rates on bank apps or GoBear — check promotional rates for new-to-bank funds
2. Use FSMOne for access to multi-bank FD rates through a single platform (see our FSMOne referral code for a sign-up bonus)
3. Note the maturity date carefully and set a calendar reminder to roll over or redeploy

Option D: Deploy into Income-Generating Assets

If your T-bill proceeds form part of a larger cash buffer and your emergency fund is already adequate, consider whether redeploying into dividend-paying S-REITs or ETFs makes sense for your financial goals. Use our Singapore retirement calculator to model how different deployment decisions affect your long-term retirement outcomes.

For reference, Singapore’s best S-REITs currently yield 5–7% annually — significantly higher than T-bill rates, though with more volatility and capital risk. This is a separate decision from your cash management strategy and not suitable for funds you may need within 12 months.
