High-yield savings accounts, September 2026 — what you’d really earn

The number on the poster is almost never the number you get. Tell the tool your balance and what you already do — credit salary, spend on a card, pay bills — and it computes each account’s real effective rate on your money, ranked by actual dollars. Re-audited against official bank pages for September, cut-off 1 September 2026. The big bonus accounts held steady this month; the movement is at the margins — Citi restructured its booster menu and MariBank added a salary bonus.

What changed since August

  • The big bonus accounts are static this month: OCBC 360 (Aug–Dec Save-bonus promo confirmed still running, max EIR 4.70%), UOB One, SC Bonus$aver, BOC SmartSaver, DBS Multiplier, UOB Stash, Trust and RHB all re-verified unchanged for September.
  • Citi restructured Interest Booster's menu — the wealth booster split into Invest +0.60% / Insure +0.60%, plus a new Borrow booster (+0.80%, S$500k home loan) and a birthday-month Celebrate booster (+0.10%), lifting the headline to 'up to 4.0%'. The everyday value is unchanged: 1.50% base on the first S$50k.
  • MariBank added a 0.20% salary-crediting bonus, lifting its banner to 'up to 3.08%' — the standing no-strings rate is still 0.88%. (OCBC also raised its Premier Dividend+ account's bonus from 1.30% to 1.70% total effective 1 Sep — a premier product outside this comparison.)
  • Watch item: Standard Chartered's Bonus$aver rate sheet is explicitly dated 1 Jul–30 Sep 2026, so a 1 Oct re-price is structurally possible — nothing announced yet. We'll re-check at the October refresh.

Comparing history? The August 2026 snapshot stays up unchanged.

The accounts, and their catches

Best for you

Standard Chartered Bonus$aver

Salary / card account
1.85%your EIR
Earns S$1,850/yr on S$100,000headline “up to 5.85%”
Medium execution riskWealth bonus lasts 6 mths

Salary ≥ S$3,000 (+0.90%) + S$1,000 card spend (+0.90%) → 1.85% EIR on first S$100k.

The 5.85% needs a S$24,000/yr insurance premium AND S$30,000 investment — and those wealth bonuses last only 6 months while the products run for years. Note: SC's current rate sheet is explicitly dated 1 Jul–30 Sep 2026 — the rates could re-price on 1 Oct; nothing is announced yet.

OCBC 360

Salary / card account
1.55%your EIR
Earns S$1,550/yr on S$100,000headline “up to 4.7%”
Medium execution riskWealth bonus lasts 12 mths

Salary ≥ S$1,800 + grow balance S$500 + S$500 card spend → 2.20% EIR on first S$100k (with the Aug–Dec Save-bonus promo). July max EIR was 4.45%.

OCBC added a Save-bonus promo (1 Aug–31 Dec 2026) that lifts the Save EIR from 0.40% to 0.65% (max EIR 4.45→4.70%) — but the bonus needs your balance to RISE by ≥S$500 every month, which gets progressively harder. The full 4.70% still also needs eligible insurance AND investment. A separate Grow bonus (+1.20%) exists for balances ≥S$250k — not modelled here. Confirm the current tiers on OCBC's page.

UOB Stash

No monthly tasks
1.50%your EIR
Earns S$1,505/yr on S$100,000headline “up to 2%”
Low execution risk

No salary or card needed — just keep your monthly average balance from falling. 1.50% EIR at S$100k.

The first S$10k earns only 0.05% and the 2.00% applies to the final S$30k tier. Balances above S$100k drop to base. Your balance must not decline month-on-month.

UOB One

Salary / card account
1.38%your EIR
Earns S$1,375/yr on S$100,000headline “up to 3.4%”
Medium execution risk

S$500 card spend + salary ≥ S$1,600 → 1.00% first S$75k, 2.50% next S$50k, 3.40% next S$25k. Max 1.90% EIR at S$150k.

The 3.40% applies only to the LAST S$25,000 tier — the true maximum effective rate is 1.90% at S$150k. Balances above S$150k earn the base rate.

BOC SmartSaver

Salary / card account
1.20%your EIR
Earns S$1,200/yr on S$100,000headline “up to 4.6%”
High execution riskWealth bonus lasts 6 mths

Salary ≥ S$3,000 (+0.50%) + card spend (+0.60% at S$750–2,500; +0.90% at ≥S$2,500) + 3 bills (+0.10%) on first S$100k.

Typical S$750–1,000 card spend earns the 0.60% tier — the advertised 0.90% needs S$2,500 EVERY month. The 4.60% adds a 6-month insurance bonus tied to a large premium; a S$1,500 minimum average balance also applies.

GXS Saving Pockets

No monthly tasks
1.08%your EIR
Earns S$1,080/yr on S$100,000headline “up to 1.08%”
Low execution risk

1.08% p.a. credited daily, no salary, spend or lock-in.

Combined account/pocket balance limits apply (the overall cap is stated in the GXS app; the 0.88% modelled above S$100k is conservative — the page shows 1.08% with no tiering). Simple and liquid, but lower than a well-run task account.

Trust Bank (Flex plan)

Salary / card account
1.00%your EIR
Earns S$1,000/yr on S$100,000headline “up to 2.4%”
Medium execution risk

Pick any 3 monthly boosts: salary ≥ S$1,500 (+0.45%), 5×S$30 card spends (+0.20% NTUC member), ≥S$100k balance (+0.30%) etc., on top of 0.05% base.

The 2.40% headline needs the referral boost (+1.20%) or S$20k in TrustInvest (+0.70%) — the everyday salary+card+balance stack tops out around 1.00%. Plans are switchable monthly; balances above S$1.2m earn 0.05%.

DBS Multiplier

Salary / card account
0.92%your EIR
Earns S$925/yr on S$100,000headline “up to 4.1%”
Medium execution risk

Income + 1 category (card) → 1.80% on first S$50k only ≈ 0.925% EIR at S$100k. More categories + higher transaction value lift it.

The 4.10% needs income + 3 categories AND S$30,000+ monthly eligible transactions. With just salary + card at S$100k, half your balance drops to base rate.

Mari Savings

No monthly tasks
0.88%your EIR
Earns S$880/yr on S$100,000headline “up to 0.88%”
Low execution risk

0.88% p.a. credited daily, no tasks.

The banner now says 'up to 3.08%' — that's 0.88% base + a 1.60% 30-day new-user boost + 0.40% ShopeeVIP + a new 0.20% salary-crediting bonus. The standing no-strings rate is still 0.88%. Fully liquid.

Maybank Save Up

Salary / card account
0.88%your EIR
Earns S$875/yr on S$100,000headline “up to 4%”
Medium execution risk

RESTRUCTURED 1 Jul 2026: salary/GIRO + card = 2 products → 1.17% bonus EIR on first S$75k; a third product lifts it to 3.08% (+ base up to 0.25%).

Salary and GIRO together count as ONE product. The 4.00% headline is base + the 3.75% marginal bonus on the last S$25k tier only — Maybank's own maximum effective bonus rate is 3.08% with 3+ products. Bonus figures below exclude the small base interest (up to 0.25%). (September check: Maybank's product page was erroring server-side, but the official 29-May notice confirms the 1 Jul structure and no newer notice exists.)

Citi Interest Booster

Wealth-relationship
0.85%your EIR
Earns S$855/yr on S$100,000headline “up to 4%”
Medium execution riskWealth bonus lasts 12 mths

1.50% base on the first S$50k (attractive with no hoops); ≈0.01% above that tier. Booster menu restructured for September.

Citi restructured the boosters: Save +0.20%, Spend +0.20%, Invest +0.60%, Insure +0.60%, plus a NEW Borrow booster (+0.80%, needs a S$500k home loan) and a NEW Celebrate booster (+0.10%, your birthday month only) — that's how the headline reads 'up to 4.0%'. The 1.50% base on the first S$50k is the real everyday value; the account stays weak above S$50k.

RHB High Yield Savings Plus

No monthly tasks
0.78%your EIR
Earns S$775/yr on S$100,000headline “up to 1%”
Low execution risk

No monthly task at all. Tiered 0.70% / 0.80% / 0.90% / 1.00% → ≈0.78% EIR at S$100k (rates cut 1 Jan 2026).

RHB cut these tiers sharply effective 1 Jan 2026 (they previously ran 1.20–1.50%). The 1.00% applies only above S$100k — the effective rate on S$100k is ≈0.78%. No-hoop alternatives (UOB Stash, GXS) now pay more.

Effective rates are computed on your stated balance from the tasks you toggle — the honest number, not the headline. Snapshot verified 1 September 2026; rates and bonus terms change without notice and the bank’s current T&C always governs. Wealth-linked rates assume you bought a qualifying product and last only 6–12 months.

Why the headline lies

  • Marginal-tier deception — UOB One’s 3.40% applies only to the last S$25,000 slice; the true maximum on S$150k is 1.90%. Maybank’s 4.00% headline is the marginal rate on its last S$25k tier — the bank’s own maximum effective bonus rate is 3.08%.
  • Booster-menu inflation — Citi’s new “up to 4.0%” needs a S$500,000 home loan for its biggest booster and even includes a +0.10% booster that applies only in your birthday month. The dependable part is the 1.50% base on the first S$50k.
  • Wealth bonuses expire — SC Bonus$aver’s 5.85% and BOC’s 4.60% run for just 6 months, while the insurance or investment you bought to unlock them runs for years.
  • Rising-balance traps — OCBC 360’s Save bonus needs your balance to grow S$500 every month, which gets harder the longer you hold.
  • Quiet cuts and quiet windows — RHB’s no-hoop tiers were halved effective 1 January 2026, Maybank restructured Save Up from 1 July — and SC’s current Bonus$aver sheet is explicitly dated only to 30 September, so watch for a 1 October re-price.
  • Execution risk — a rate is worth nothing in a month you miss the salary code, GIRO date, or card-posting window. A reliable 1.50% can beat a fragile 1.95%.

Where should money above S$100k go?

An adviser can help you:

  • Split cash across banks so deposit insurance actually covers it, and park the overflow sensibly
  • Weigh a savings account against a fixed deposit, T-bill or SSB for money you won’t touch
  • Judge any wealth-linked bonus honestly — whether the insurance or investment stands on its own merits

Quick answers

What is the best high-yield savings account in Singapore in September 2026?For a S$100,000 balance with salary credit, a rising balance and card spend — and no new wealth purchase — OCBC 360 delivers about 2.20% effective interest (its Save-bonus promo runs to 31 December 2026) and Standard Chartered Bonus$aver about 1.85%. For no monthly tasks, UOB Stash reaches about 1.50% effective and GXS pays 1.08% flat. All structures were re-verified against official bank pages on 1 September 2026.
What changed in the Citi Interest Booster account?Citi restructured the booster menu: the old combined wealth booster is now split into Invest (+0.60%) and Insure (+0.60%), joined by a new Borrow booster (+0.80%, requiring a S$500,000 home loan) and a Celebrate booster (+0.10%, birthday month only) — lifting the advertised ceiling to 4.0%. The everyday value is unchanged: a strong no-hoop 1.50% base on the first S$50,000, weak above that.
Is MariBank's 3.08% savings rate real?The 3.08% banner is a stack: 0.88% standing base + a 1.60% new-user boost (first 30 days only) + 0.40% for ShopeeVIP members + a new 0.20% salary-crediting bonus. The rate every existing customer earns with no conditions is 0.88%.
Will Standard Chartered Bonus$aver rates change in October 2026?Possibly — SC's current rate sheet is explicitly dated for 1 July to 30 September 2026, which creates a natural 1 October re-pricing window. Nothing has been announced. We re-check every account monthly; leave your email in the rate-alert box to be notified.
How much of my savings is protected by deposit insurance in Singapore?SDIC protects up to S$100,000 per depositor per bank, combined across savings, current and fixed deposits at that Scheme member. Most account bonuses also stop above S$100,000–150,000, so overflow cash is often better split across banks or placed in a fixed deposit or T-bill.

Official sources

Effective rates are computed on the balance and tasks you select, using each bank’s published tier and bonus structure verified 1 September 2026(the Maybank revision notice and Citi Interest Booster page re-verified manually in a browser the same day; Maybank’s Save Up product page was returning a server error at the check, so its structure is confirmed from the bank’s official 29 May notice). Maybank figures exclude its small tiered base interest (up to 0.25% p.a.) because the base tier split is not published on the programme page — actual earnings will be slightly higher. Estimates are for comparison and education only — bank eligibility, transaction recognition and bonus calculations remain subject to each institution’s prevailing terms, and rates change without notice. Insurance and investment products carry separate suitability, cost, risk and liquidity considerations and should never be bought for a savings bonus alone. Not financial advice — verify the latest official source before acting.
