Today’s 6-month Singapore T-bill auction (BS26117A) is expected to deliver a cut-off yield near 1.55%–1.56%, continuing the downward drift from July’s 1.59% peak. But with Citibank now offering 2.00% p.a. on 6-month fixed deposits and the August 2026 Singapore Savings Bond (SSB) locking in a 2.25% 10-year average, Singapore retail investors face a real decision: is the T-bill still worth it?
This is an editorial analysis. Not financial advice. Data verified as at 27 August 2026.
What’s Happening at Today’s T-Bill Auction (BS26117A)?
Today marks the bi-weekly 6-month Singapore Treasury Bill (T-bill) auction. The issue code is BS26117A, with an issuance size of S$8.7 billion — the same as the previous auction on 13 August.
Based on the secondary market closing yield of 1.55% as of 20 August 2026, and the 3-month MAS bill cut-off yield of 1.47% on 18 August, the market is pricing in a yield close to — or slightly below — last fortnight’s 1.56% cut-off.
Applications for the previous auction surged to S$18.5 billion (from S$18.1 billion in July), signalling strong demand that could push the yield down further. The same issuance size against higher demand typically compresses the cut-off yield.
For Singapore investors who applied via ATM, internet banking, or CDP account by 9pm on 26 August, results will be announced today. Those who missed this round have until mid-September for the next auction window.

Why Are T-Bill Yields Sliding in August 2026?
On the international side, the US 10-year Treasury yield dipped to 4.65% as of 19 August, while the US 1-year yield eased to 3.98%. The Federal Reserve kept rates on hold at its July meeting but signalled it may maintain higher rates through 2026 — a “higher for longer” backdrop that limits how far Singapore yields can fall.
Domestically, Singapore’s 10-year government bond yield rose to 2.36% by mid-August, up from 2.28% two weeks earlier. This divergence — longer-dated yields rising while short-term T-bill yields compress — reflects a re-steepening of the yield curve, typically a sign investors are locking in longer duration at higher rates.
The demand side is equally important: with S$18.5 billion chasing S$8.7 billion of T-bills in the August 13 auction, the bid-to-cover ratio exceeded 2x. This level of oversubscription compresses the cut-off yield regardless of global rate conditions.

T-Bills vs Fixed Deposits vs SSBs: The August 2026 Showdown
Here’s the hard truth: for the first time in months, the 6-month T-bill is no longer the highest-yielding short-term option. Let’s compare.
| Product | Rate (p.a.) | Tenure | Min. Amount | Provider | Capital Safety |
|---|---|---|---|---|---|
| 6M T-Bill (Aug 27) | ~1.55% | 6 months | S$1,000 | MAS / Singapore Govt | Government-backed |
| 6M Fixed Deposit | 2.00% | 6 months | S$10,000 | Citibank | SDIC up to S$100K |
| 12M Fixed Deposit | 1.75% | 12 months | S$10,000 | Bank of China | SDIC up to S$100K |
| SSB Aug 2026 – 1-year | 1.52% | 1 year | S$500 | MAS / Singapore Govt | Government-backed |
| SSB Aug 2026 – 10-yr avg | 2.25% | Up to 10 years | S$500 | MAS / Singapore Govt | Government-backed + redeemable |
| OCBC 360 (promotional) | Up to 2.20% | Promotional period | S$1,000 | OCBC | SDIC up to S$100K |
| Maybank iSavvy / HSBC EGA | Up to 1.68% | Fresh funds promo | Varies | Maybank / HSBC | SDIC up to S$100K |

The gap is striking: Citibank’s 6-month fixed deposit at 2.00% p.a. outperforms the T-bill by approximately 0.45 percentage points. On S$50,000, that difference translates to roughly S$112.50 in extra interest over six months.

The Singapore Savings Bond: Long-Term Lock-In at 2.25%
The August 2026 SSB issuance (GX26090V) is the most compelling option for investors who don’t need their cash back within the next year. The 10-year average return of 2.25% p.a. significantly exceeds both T-bill yields and most fixed deposit options, and SSBs allow early redemption at any time without penalty — a flexibility no fixed deposit provides.
The 1-year return of 1.52% is admittedly lower than the T-bill yield, so for investors focused purely on the next 6 months, the SSB is not the optimal choice. But for those building a bond ladder — stretching idle cash across 1, 2, and 5-year horizons — the SSB is a natural complement to T-bills.
The September 2026 SSB is projected to offer a 10-year average of approximately 2.33%, based on secondary market levels as of mid-August.

Should You Still Apply for T-Bills in August 2026?
Yes — but with eyes wide open. Here is the TKN framework for deciding:
Apply for T-bills if: You want direct government backing, your cash amount is below S$10,000 (below the Citibank FD minimum), you have already maxed your SSB allocation (S$200,000 lifetime limit), or you need the 6-month maturity cycle to match a specific liability.
Consider the 6M FD (Citibank 2.00%) if: You have S$10,000 or more in available cash, can lock it for exactly six months, and are comfortable with SDIC insurance as your capital protection mechanism. The yield advantage of 0.45 percentage points is meaningful at scale.
Consider the SSB if: You have a 3–10 year horizon for idle funds, want to avoid reinvestment risk, or are building a laddered portfolio with Singapore government-backed instruments.

What Happens After Today’s Auction Results?
MAS will announce the cut-off yield for BS26117A later today. Successful applicants receive their T-bill on 1 September 2026 (the issue date), with the T-bill maturing in March 2027.
If you applied via cash (bank account), the full bid amount was deducted at application; the discount amount is returned to your account after allotment. If you bid via CPF OA funds, interest accrues only on the actual T-bill principal during the tenure.
We will update our live T-bill auction results tracker once MAS publishes today’s cut-off yield.
Bottom Line for SG Investors
Today’s T-bill auction (BS26117A) is expected to deliver a yield near 1.55% — still a solid, government-backed return for short-term cash. But in August 2026, T-bills are no longer the default best option. Citibank’s 6-month fixed deposit at 2.00% and the August 2026 SSB’s 2.25% 10-year average both present materially better alternatives depending on your time horizon and minimum investment.
Don’t apply for T-bills on autopilot. The landscape shifts every fortnight. If you have S$10,000 or more and can lock it for six months, the fixed deposit is winning in August 2026.
Frequently Asked Questions
What is today’s Singapore T-bill auction?
Today (27 August 2026) is the bi-weekly 6-month Singapore T-bill auction with issue code BS26117A. The issuance size is S$8.7 billion. Results are expected from MAS later today, with the T-bill issued on 1 September 2026.
What is the expected cut-off yield for today’s T-bill auction?
Based on the secondary market closing yield of 1.55% on 20 August 2026 and trends from recent auctions, the expected cut-off yield is approximately 1.55%–1.56% p.a. High demand (S$18.5 billion bids vs S$8.7 billion issuance in the previous auction) may push it slightly lower.
Is the T-bill the best place to park cash in Singapore right now?
Not necessarily. Citibank currently offers 2.00% p.a. on 6-month fixed deposits (minimum S$10,000), outperforming the T-bill. The August 2026 SSB offers a 2.25% 10-year average with full redemption flexibility. T-bills remain attractive for amounts below S$10,000 or for those who prefer direct government backing over SDIC insurance.
How does the T-bill compare to the Singapore Savings Bond?
For the short term (6 months), the T-bill’s ~1.55% yield is slightly higher than the SSB’s 1.52% first-year rate. However, the SSB offers a significantly better 10-year average of 2.25% p.a. and allows early redemption without penalty — making it better for idle cash with no fixed short-term deadline.
What is the minimum amount to apply for a Singapore T-bill?
The minimum application is S$1,000, in multiples of S$1,000. You can apply via ATM, internet banking (DBS/POSB, OCBC, UOB), or mobile banking using cash, CPF OA, or SRS funds. Applications for today’s auction closed at 9pm on 26 August 2026.
Can I use CPF funds to invest in T-bills?
Yes. CPF Ordinary Account (OA) funds can be invested in T-bills under the CPF Investment Scheme (CPFIS). However, CPF OA earns a guaranteed 2.5% p.a. — so using OA funds for T-bills yielding ~1.55% effectively costs you the 0.95 percentage point differential. This is generally not recommended unless T-bill yields significantly exceed 2.5%.
When will today’s T-bill results be announced?
MAS typically announces T-bill auction results on the auction day in the late afternoon or early evening. Results for BS26117A will be published at mas.gov.sg on 27 August 2026. Successful applicants receive their T-bill allocation on 1 September 2026.
What is the next Singapore T-bill auction after today?
The next 6-month T-bill auction is expected in mid-September 2026. MAS publishes the full auction calendar at mas.gov.sg/bonds-and-bills/auctions-and-issuance-calendar. Check our tracker for the exact date once confirmed.
Is Singapore Savings Bond or T-bill better for CPF funds?
Neither is generally recommended for CPF OA funds, since the CPF OA guaranteed rate of 2.5% p.a. exceeds current T-bill yields of ~1.55% and the SSB 1-year rate of 1.52%. The SSB 10-year average of 2.25% still falls slightly below the CPF OA rate. Leave CPF funds in CPF where they earn the guaranteed 2.5% unless you have a specific CPFIS-eligible strategy.
