Singapore Passive Income Yield Ladder [August 2026]: T-Bills vs FD vs SSB vs MMF vs Endowment

Singapore short rates have held above 2.5% for most of 2026 after the 2023 to 2024 rate rise. The result is a genuine passive income ladder for SGD-denominated savings, with Treasury bills, fixed deposits, Savings Bonds, and money market funds all delivering yields that beat the historical average of the last decade. Endowment plans remain a specific-use vehicle rather than a pure yield play. This guide compares the five options on yield range, lock-in period, and downside risk, refreshed for August 2026.

TL;DR: T-bills 2.9 to 3.5% highest; SSB 2.5 to 3.0% first-year safest; MMF 2.8 to 3.4% most liquid

Highest yield right now: 6-month T-bills at 2.9 to 3.5% cut-off yield range in 2026, based on recent auction outcomes. Government-backed and tax-free for individuals.

Safest with government backing: Singapore Savings Bonds at 2.5 to 3.0% first-year interest and 2.8 to 3.2% 10-year average. Principal guaranteed monthly.

Most liquid: Money market funds at 2.8 to 3.4% net yield with T+1 to T+3 redemption. Small credit risk from underlying instruments.

Certainty at booking: Fixed deposits at DBS, UOB, OCBC 2.6 to 3.2% on promotional 6-to-12-month tenors. SDIC insured to S$100,000 per bank.

Long-term guaranteed capital: Endowment plans 2.8 to 4.0% guaranteed IRR plus non-guaranteed bonuses, but 3-to-25-year lock-in and steep early exit penalties.

Yields refresh monthly. As of August 12, 2026. Verify current yields directly with MAS, DBS, UOB, OCBC, and each fund manager before committing capital.

Treasury bills, in detail

MAS Treasury bills are short-duration Singapore Government debt instruments. They are auctioned regularly and yield a discount to face value paid at maturity.

How they work. You bid on a T-bill at auction. The bid can be competitive (specifying a yield you are willing to accept) or non-competitive (accepting the average cut-off yield). At maturity, you receive S$1,000 per bill. Interest is the difference between purchase price and maturity value.

2026 yield history. 6-month T-bill cut-off yields have ranged 2.90 to 3.50% across auctions in the first half of 2026, with typical auctions clearing around 3.0 to 3.3%. 1-year T-bills have cleared 2.80 to 3.40%. Yields respond to MAS monetary policy and global rate expectations.

Access and mechanics. Bid via DBS, OCBC, or UOB internet banking, SRS operator if using SRS funds, or CPFIS if using CPF Ordinary Account funds. Auctions occur twice per month for 6-month T-bills, quarterly for 1-year T-bills. Minimum S$1,000, increments of S$1,000. Settlement 2 business days after auction result.

Pros: Highest yield among government-backed instruments; tax-free for individuals; short duration limits interest rate risk.

Cons: Yields determined at auction (uncertain until result); secondary market resale before maturity may result in capital loss; not automatically renewed; some administrative work per bidding cycle.

Best for: Cardholders with S$1,000+ per lot to deploy, comfortable with auction mechanics, targeting 3 to 6 month time horizon per lot.

Confirm current auction calendar and results at MAS Bonds and Bills.

Fixed deposits, in detail

Fixed deposits at DBS, UOB, and OCBC (and second-tier banks) are the most familiar SGD passive income vehicle for retail savers.

How they work. Deposit a fixed sum for a fixed tenor at a fixed interest rate. At maturity, principal plus interest is returned. Early break generally forfeits interest.

August 2026 promotional rates. Top-tier promotional rates on 6-to-12-month tenors at DBS, UOB, and OCBC have ranged 2.6 to 3.2% in mid-2026, with occasional 3.3 to 3.5% spikes when banks compete for balance sheet ahead of quarter end. Rates on 18-to-24-month tenors have been 2.5 to 3.0%. Second-tier banks (Maybank, RHB, ICBC, Bank of China Singapore, HL Bank) occasionally offer 10 to 30 basis points higher.

Minimum tier structure. Promotional rates typically require S$10,000 to S$20,000 minimum with the target tenor. Below-tier deposits earn the standard (much lower) rate.

Pros: Yield certain at booking; SDIC insurance to S$100,000 per bank per depositor; simple to set up via internet banking; no mark-to-market volatility.

Cons: Locked capital for tenor; opportunity cost if rates rise; forfeit interest if broken early; promotional rates change frequently.

Best for: Cardholders who want certainty and simplicity; balances up to SDIC limit; horizons matched to available tenors.

Verify current rates at DBS Fixed Deposit, UOB Fixed Deposit, and OCBC Time Deposit.

Singapore Savings Bonds, in detail

Singapore Savings Bonds are a MAS-issued retail bond designed as a safe long-duration savings vehicle for Singapore residents.

How they work. Buy in any monthly issue with S$500 minimum. Interest is paid every 6 months. Rate steps up over 10-year term to match Singapore Government Securities yields. Redeem any month with no penalty and receive principal plus accrued interest.

August 2026 tranche. The SSB tranche opening for application in August 2026 offers first-year interest and 10-year average return that varies month to month. Recent tranches have offered approximately 2.5 to 3.0% first-year interest and 2.8 to 3.2% 10-year average return. Check the exact rate for the current tranche at the MAS SSB latest issue page at the start of each application window.

Personal holding limit. S$200,000 across all SSB issues per individual. This binds for larger savers; supplement with T-bills or FD above the limit.

Pros: Government-backed; principal guaranteed at any redemption month; step-up interest rewards holding to 10 years; tax-free.

Cons: Lower first-year interest than T-bills or top FDs; monthly redemption window (not instant); S$200,000 cap.

Best for: Long-horizon savers who want capital-guaranteed passive income and monthly liquidity; savers uncomfortable with auction mechanics of T-bills.

Money market funds, in detail

SGD money market funds are mutual funds that invest in short-duration high-quality fixed income instruments and offer near-cash liquidity.

How they work. Buy fund units at the daily NAV. The fund invests in Singapore Treasury bills, bank fixed deposits, government-issued paper, and select commercial paper. Distributions are typically monthly. Redeem any business day; funds settle T+1 to T+3.

2026 yields. Major SGD MMFs including Fullerton SGD Cash Fund, Phillip Money Market Fund, Nikko AM Shenton Money Market Fund, and Lion-Nomura Japan Growth Fund's cash counterpart have yielded 2.8 to 3.4% net of management fee in mid-2026. Management fees typically 0.15 to 0.30% per annum.

Access. Buy through banks (DBS, UOB, OCBC), through the fund manager direct, or through robo-advisers (Endowus, StashAway, MoneyOwl, Syfe Cash+) that wrap MMF portfolios.

Pros: Yield close to T-bill without lock-in; daily liquidity; no auction mechanics; simple monthly compounding.

Cons: Small NAV volatility possible if underlying instruments experience credit event; management fee erodes yield; not government-guaranteed (though most SG MMFs hold high-grade paper).

Best for: Cardholders wanting close-to-T-bill yield with instant access; emergency fund parking; short-horizon savings.

---

Endowment plans, in detail

Endowment plans are insurance products that combine long-term savings with a life insurance component.

How they work. Pay a single premium (or regular premiums) for a defined term (3 to 25 years). Receive back a guaranteed maturity value plus non-guaranteed bonuses. Some plans allow partial withdrawal or premium holidays.

2026 yield range. Guaranteed IRR on the guaranteed portion of most 2026 SGD single-premium endowments has been 2.8 to 4.0% depending on term and insurer (Great Eastern, AIA, Manulife, NTUC Income, Singlife). Non-guaranteed bonuses lift projected total IRR to 3.5 to 4.5%. Actual delivered IRR depends on insurer par fund performance.

Pros: Guaranteed capital return at maturity; life insurance rider covers death benefit; discipline of long-term saving; some plans offer tax-relief on SRS or CPF-based premiums.

Cons: Long lock-in (3 to 25 years); steep early surrender penalty (often 30 to 50% haircut in first 3 years); less transparent fees; distribution channel commissions embedded; non-guaranteed portion depends on par fund performance.

Best for: Specific goals with long horizons (child education fund, guaranteed maturity for retirement bucket); cardholders who value life insurance component; SRS or CPF holders looking for guaranteed capital return with insurance rider.

Not for: Pure yield chasing; savings you may need in 5 years or less; anyone uncomfortable with early exit penalties.

What this means in practice

A Singapore saver with S$100,000 in idle SGD cash in August 2026 might structure as:

• S$30,000 in a 6-month T-bill for yield certainty at auction cut-off (targeting 3.0 to 3.3%)
• S$30,000 in Fullerton SGD Cash Fund or Endowus Cash Smart Core for daily liquidity (targeting 2.9 to 3.2% net)
• S$25,000 in a Singapore Savings Bond August 2026 tranche for long-duration principal-safe holding (2.5 to 3.0% first year, stepping up)
• S$15,000 in a promotional 12-month FD at UOB or OCBC (targeting 2.9 to 3.1%)

Weighted average yield ~2.9 to 3.1% net, with a mix of liquidity across daily (MMF), 6 months (T-bill), monthly (SSB), and 12 months (FD).

A second scenario: a saver with S$500,000 must diversify beyond the S$200,000 SSB cap and the S$100,000 SDIC per-bank cap:

• S$200,000 across two SSB tranches (single individual cap)
• S$100,000 in T-bill ladder rolling every 3 months
• S$100,000 in a promotional FD at DBS or UOB
• S$50,000 in a second-tier bank promotional FD (Maybank, RHB, or Bank of China)
• S$50,000 in an SGD money market fund

Weighted yield ~2.9 to 3.2% with each instrument sitting within its safety envelope.

A third scenario: a saver in their 30s with a 20-year horizon and a young child, looking for a child education fund. Endowment plan at S$50,000 to S$100,000 single premium, projected total IRR 3.5 to 4.2%, guaranteed IRR 2.8 to 3.5%, with education marker maturity dates aligned to college years. Complement with SSB for principal-safe portion and equity index ETFs for growth exposure.

ShopBack does not offer cashback on T-bill purchases, SSB subscriptions, fixed deposit bookings, or MMF units directly since these are non-merchant financial instruments. What ShopBack does offer is cashback on Singapore online spend at hundreds of merchants including grocery, dining, and travel bookings, which frees up more cash for the yield ladder above.

When this does NOT apply

• You need capital in less than 1 month. Locked instruments (FD, T-bill) do not fit. Use MMF or SSB (monthly redemption) instead.
• You want equity-like returns. The whole ladder is fixed-income. Expected returns are capped by prevailing SGD short rates. For higher returns, add equity index ETFs and accept market risk.
• Your income sits mostly in USD, EUR, or other non-SGD currency. SGD instruments may create FX risk against your primary spending currency. Consider USD T-bills or your home-currency equivalents.
• You are near retirement and need income now. Endowments with long tenors do not fit. SSB with monthly interest payments or FD interest payouts to bank account do fit. Consult a financial planner on drawdown structure.
• You are in high tax bracket in a country other than Singapore. SG tax-free treatment of T-bill and SSB interest for SG-resident individuals may not apply to foreign residents. Check your home country tax treatment.
• You want inflation-hedged return. None of these instruments guarantee real (inflation-adjusted) return. If Singapore CPI runs 3.0 to 3.5% (as it has in 2024 to 2026 periods), a 3.0% nominal yield is close to break-even in real terms.

Are Singapore T-bills better than fixed deposits in 2026?

T-bill yields have generally been 20 to 50 basis points higher than top promotional FD rates in 2026 on comparable tenor, though the gap varies. T-bills are government-backed and tax-free; FDs offer certainty at booking with SDIC insurance to S$100,000 per bank.

Are endowment plans a good passive income option in Singapore in 2026?

Endowments offer 2.8 to 4.0% guaranteed IRR plus non-guaranteed bonuses (projected 3.5 to 4.5% total IRR), but lock capital for 3 to 25 years with steep early exit penalties. Suit specific goals, not pure yield chasing.

What is the safest passive income option in Singapore?

Singapore Savings Bond, backed by the Singapore Government with principal guaranteed at any redemption month. T-bills are similarly government-backed but require holding to maturity for guaranteed return.

How do I buy a Singapore T-bill in 2026?

Via DBS, OCBC, or UOB internet banking, SRS operator (for SRS funds), or CPFIS (for CPF OA funds). Auctions run twice monthly for 6-month T-bills. Minimum S$1,000, increments of S$1,000.

Can I redeem Singapore Savings Bonds early?

Yes, any month, with no penalty. Principal returned plus accrued interest to redemption date.

What is the minimum investment for T-bills, FD, SSB, and MMF in Singapore?

T-bill S$1,000; FD S$1,000 to S$20,000 depending on tier; SSB S$500 with S$200,000 lifetime cap per individual; MMF S$1,000 to S$5,000; endowment typically S$10,000 to S$50,000 single premium.

Should I ladder T-bills or lock in a longer fixed deposit in 2026?

Ladder T-bills if you expect rates to stay elevated or rise. Lock a 12-to-18-month FD if you expect Singapore short rates to fall in the next 12 months.

Are Singapore T-bill interest payments taxable?

T-bill interest for individuals is not taxable in Singapore. Same treatment for SSB interest and bank deposit interest to individuals.
