Singapore Business Bank Accounts: Comparing Minimum Balance

Curious which option actually saves you cash: a legacy bank or a fintech challenger? This guide compares how traditional and fintech providers set that crucial threshold that affects real operating funds.

Minimum balance rules can make a big difference to payroll, supplier payments and tax outgoings. Some banks ask for S$1,000–S$5,000 or require a high average daily sum to waive monthly fees. Fintechs often advertise S$0 requirements but may add setup, FX or usage charges.

This article is a practical comparison of bank accounts and non-bank alternatives. Expect clear notes on waiver rules, fall-below fees and when charges trigger.

We’ll help you shortlist based on how much cash you keep, fee types, multi-currency needs and transaction patterns. Later sections match providers head-to-head so you can judge which setup fits your cash flow.

Key Takeaways

• Understand how a set threshold affects available cash for day-to-day needs.
• Compare traditional banks and fintechs on waivers, monthly charges and FX rules.
• “Cheapest” depends on fee interactions and how often you transact.
• Use the match-ups later to narrow options by currencies and fee profiles.
• Figures come from published pricing; promotions and waivers change over time.

Why minimum balance matters for Singapore SMEs and growing companies

How a set cash threshold changes what your company can spend each month is one of the simplest—and most overlooked—costs of running an account. Keeping funds at a set level effectively reserves working capital and reduces cash available for inventory, payroll and marketing.

Cash flow impact: working capital tied up vs available for spending

Holding S$5,000 to avoid a fall-below with UOB eBusiness, or S$1,000 for an OCBC Business Growth account, cuts liquidity for early-stage firms.

Scenario: if a startup keeps S$5,000 idle, that cash cannot pay suppliers or fund ads. The opportunity cost can slow growth.

Hidden costs: fall-below fees, monthly fees and waivers

Beyond the headline threshold there are fall-below fees, monthly service charges and annual charges. DBS may waive a S$40 monthly fee only at a S$10,000 ADB. Maybank uses a S$1,000 ADB rule.

Promotional waivers can mask long-run costs. Transaction pricing for FAST/GIRO and telegraphic transfers also adds up.

When a corporate bank relationship still pays

Strong relationships and legacy payment flows make a corporate bank account worth the extra cost for some firms. It gives credibility, local rails and specialised services.

Fintechs like Airwallex, Wise and Aspire often offer S$0 thresholds and suit variable cashflows, frequent international transfers and multi-currency needs.

How minimum balance rules work in a corporate bank account

Small wording changes can change your costs. Know the difference between an initial deposit and a minimum average daily requirement before you open an account.

Initial deposit versus average daily

The initial deposit is what you must place at opening. Some providers list S$0; others ask for S$1,000 at start.

The average daily measure is what the provider computes over a month. OCBC uses S$1,000 as an example; UOB commonly uses S$5,000.

How fall-below charges are calculated

Banks tally daily sums, average them, then compare that figure to the threshold. If the average falls short, a fall-below charge applies.

Even a few low days can tip the average and trigger a fee. That matters for seasonal sellers or firms with project-based receipts.

Waivers and promotional periods

Promotions vary: OCBC may have monthly fees waived for the first two months, UOB can waive fall-below penalties for 12 months, and CIMB often waives fees in the first year.

Model costs over 12 months — waived first months can hide ongoing charges that appear once the promotion ends.

“Confirm which fees are waived, for how long and what cancels the waiver.”

• Check which fees are waived and whether the waiver is automatic.
• Ask what actions void the promotion and whether transaction thresholds apply.
• Pick the option that matches your cashflow and transaction patterns.

Snapshot comparison of Singapore business bank account minimum balances

Here’s a quick overview that separates headline numbers from the fees that follow. Use this to compare what providers list as a threshold and what they actually charge when conditions are not met.

Traditional banks at a glance

OCBC Business Growth: S$1,000 threshold; S$10 monthly fee waived for the first two months. Fall‑below fees apply thereafter.

UOB eBusiness: S$5,000 threshold; fall‑below fee waived for 12 months and an annual fee of S$35.

Maybank FlexiBiz: S$1,000 threshold with a typical S$10 fall‑below charge.

DBS Business Multi‑Currency: headline S$0 threshold but a S$40 monthly service fee unless ADB ≥ S$10,000; annual fee S$50.

CIMB SME: S$0 threshold with no fall‑below fee and monthly charges waived in year one (then S$8).

Fintech and non‑bank providers at a glance

Wise: S$0 threshold, one‑time S$99 set‑up fee and transaction FX fees from ~0.26%.

Aspire: S$0 threshold, free local transfers and straightforward pricing for SMEs with cross‑border needs.

Airwallex: S$0 threshold; free local transfers, SWIFT cost ~S$20–35 and FX spreads around 0.4–0.6%.

Revolut: S$0 threshold; plan‑based limits and variable fees depending on subscription tier.

YouBiz: S$0 threshold, supports nine currencies and applies variable usage fees.

• Quick take: Traditional providers cluster around S$1,000–S$5,000 thresholds. Fintechs mostly list S$0 but monetise via FX, plans or transfer fees.
• Notable exceptions: DBS shows a S$0 opening threshold but enforces meaningful monthly service charges unless ADB is high. CIMB offers a rare S$0 option with no fall‑below fee.
• What headline numbers hide: transaction pricing, waiver expiry, FX spreads and SWIFT or agent fees. For a deeper comparison, see this compare business bank accounts guide.

Traditional banks compared by minimum balance and fall-below fees

Below is a side‑by‑side look at five legacy providers and the costs that matter: threshold rules, fall‑below exposure, monthly and annual charges, and what each waives.

OCBC Business Growth

Threshold: S$1,000. Fall‑below: S$15 when ADB Monthly: S$10, waived for first two months. International transfer ~S$30 + agent fees.

Note: S$1,000 is manageable for many SMEs, but costs recur after the waiver ends.

UOB eBusiness

Threshold: S$5,000. Fall‑below: fee waived for 12 months. Monthly/annual: S$15 monthly, S$35 annual when conditions unmet.

Note: A higher threshold ties up cash and reduces flexibility for startups.

Maybank FlexiBiz

Threshold: S$1,000. Fall‑below: S$10. Outward remittance attracts commissions and agent/cable charges.

DBS Business Multi‑Currency

Threshold: S$0 headline but a S$40 monthly fee applies unless ADB ≥ S$10,000. Annual fee S$50. International transfers ~S$30.

Note: This creates a de facto soft threshold for firms that want to avoid the service charge.

CIMB SME

Threshold: S$0 with no fall‑below fee. Monthly fee waived for 12 months, then S$8. Free local FAST/GIRO; international transfer ~S$15.

• Decision tip: For primarily local SGD ops, CIMB, OCBC or Maybank can work. For frequent international payments, compare the full fee stack rather than the headline threshold.

Fintech and non-bank providers with no minimum balance requirements

Removing a required float frees working capital, but it means costs appear in transactions, FX and plans rather than held cash.

Wise Business

Wise Business offers a S$0 opening and supports 40+ currencies for holding and paying. There is a one‑time S$99 setup fee and FX fees from ~0.26%.

Best for: paying overseas contractors and multi‑currency payroll without tying up funds.

Aspire Business Account

Aspire lists no required float, no monthly charge and fee‑free local transfers. It supports local details in SGD, USD, GBP and EUR.

International transfers use SWIFT or local rails and can start from about US$8, so check transfer fee profiles.

Airwallex Business Account

Airwallex Business Account suits global‑first firms. It supports 20–23+ currencies with local rails, free local transfers and SWIFT costs around S$20–35.

Revolut Business and YouBiz

Revolut moves costs into plan limits and per‑transfer charges; free allowances exist but FX outside allowances can add fees.

YouBiz offers no monthly fee, nine currency support and variable transfer costs with tight FX spreads (0.1–0.4%).

“If you need predictable monthly spend, compare plan pricing; if low FX friction matters, compare spreads.”

• Zero float keeps cash agile, ideal for startups with uneven income.
• Fintechs rarely offer branches or cash handling—factor that into your service needs.

OCBC Business Growth vs UOB eBusiness account for startups

Choosing between OCBC Business Growth and UOB eBusiness often comes down to how much runway you can afford to lock away. Startups should compare cash tied up with waiver length and transaction costs.

Minimum exposure and first-year fee risk

OCBC requires S$1,000 and waives the S$10 monthly fee for the first two months. If the monthly average falls below S$1,000, a fall-below charge (about S$15) can apply.

UOB asks for S$5,000. It waives fall-below penalties for 12 months and suspends the S$15 monthly fee during that period. After year one the ADB rule reinstates fee triggers and a S$35 annual fee may apply.

Day-to-day transactions, payroll and quotas

OCBC includes 80 free FAST/GIRO items, then GIRO ≈ S$0.20 and FAST ≈ S$0.50. International transfers cost roughly S$30 plus agent fees and there’s a S$50 early closure fee within 12 months.

UOB charges FAST ≈ S$0.50 and GIRO ≈ S$0.20 but may offer rebates. Payroll-heavy startups should model how quickly free allowances are used.

Decision checklist for the business owner

• Cash test: Can you keep S$5,000 idle for runway? If not, OCBC is simpler.
• First-year plan: Confirm waived first months and when fees return.
• Transactions: Map expected monthly FAST/GIRO volumes and international transfers against quotas and per‑transfer costs.

DBS Business Multi-Currency Account vs Airwallex vs Wise for multi-currency needs

If your firm invoices or pays in multiple currencies, the right multi-currency account can cut conversion losses and simplify reconciliation.

Currencies supported and receiving details

DBS Business Multi-Currency Account supports SGD plus a defined set of 9–13 foreign currencies and offers standard local receiving details for key markets.

Airwallex Business Account holds 20–23+ currencies and supplies local account details in many corridors, making collections straightforward.

Wise Business lets you hold 40+ currencies with local details in nine+ markets, ideal for global receipts and simpler reconciliation.

FX pricing: bank spreads vs fintech mark-ups

Banks often embed spreads and vary rates by channel. DBS may apply better online pricing but charges more in-branch; FX fees online can be negligible, otherwise a tiered markup applies (for example 1/8% with set minimums).

Fintechs publish percentage-based mark-ups. Airwallex typically charges ~0.4% on major pairs and ~0.6% on others. Wise uses a mid-market model with fees from ~0.26% and transparent routing costs.

International transfer fees and local rails

DBS commonly routes via SWIFT with an outward fee ~S$30 and possible intermediary charges. This can add to the effective cost per transfer.

Airwallex uses local-rail corridors with S$0 fees on many routes and SWIFT only where needed (S$20–35). Wise prices per route and tends to be cost-competitive on most corridors.

When a multi-currency option beats an SGD-only solution

Choose the DBS route if you need a corporate bank presence, local branch services and can meet ADB rules to avoid the S$40 monthly fee.

Pick Airwallex for operational multi-currency services, local receiving details and low-cost local rails.

Choose Wise when transparent FX, broad currency holding and predictable transfer fees are priorities.

Decision rule: pick the option that matches how often you transact in foreign currencies and whether you value a full bank ecosystem or lean fintech services.

CIMB SME Account vs Maybank FlexiBiz for low-balance businesses

For firms that run lean, the fine print on low‑threshold offerings determines real monthly costs.

Minimum exposure: S$0 vs S$1,000 and what it costs each month

The cimb sme account lists S$0 and carries no fall‑below fee. That means firms can run near‑zero without recurring penalties.

The maybank flexibiz account typically uses an ADB of S$1,000. If the ADB falls short, a S$10 fall‑below fee may apply and recur each month.

Monthly fees, waived first months and remittance pricing

CIMB waives monthly charges for the first 12 months, then applies about S$8 per month. It also offers unlimited free FAST and GIRO transfers.

Maybank often has no routine monthly maintenance fee, but it monetises via fall‑below charges and layered remittance costs. Overseas transfers can show as commission + agent + cable fees (examples: ~S$20 overseas, ~S$10 to Malaysia in some snapshots).

Local transfers and typical transaction patterns

For firms that send many local payments, unlimited free FAST/GIRO at CIMB cuts per‑month spending more than a zero opening requirement alone.

Conversely, a low‑transaction consultancy that keeps steady sums may prefer Maybank for its regional reach, provided the ADB stays above the S$1,000 trigger to avoid the S$10 monthly fee.

“Confirm how the average daily figure is calculated and whether rebates require unusually high ADBs.”

• Who it suits: CIMB works well for low‑cash, high‑local‑transfer firms. Maybank fits firms needing Malaysia rails or regional services if they can maintain the ADB.
• Pre‑opening check: Ask how ADB is computed and whether any remittance rebates demand balances that mismatch your stage.

Beyond minimum balance: fees that change the true cost of a bank account Singapore businesses use

Fixed thresholds are only part of the story; recurring charges often decide which option truly costs less.

Monthly and annual fees quickly eclipse one‑off fall‑below charges. DBS, for example, lists a S$40 monthly fee (waived at S$10,000 ADB) and a S$50 annual fee. Early closure penalties (DBS S$50

Transaction fees bite next. Local transfers commonly cost ~S$0.20 for GIRO and ~S$0.50 for FAST after free quotas. CIMB stands out with unlimited free FAST/GIRO; fintechs like Airwallex use S$0 local rails on many corridors.

Overseas payments and hidden addons

Telegraphic transfers usually combine an initiating fee, intermediary charges and agent or cable fees. Expect S$20–35 for SWIFT routing on some services and S$30+ on traditional rails.

“Audit fees by usage, not by headline number.”

• Model monthly totals: maintenance, per‑transfer, early closure and SWIFT/agent fees.
• Check waiver mechanics: ADB waivers act as a hidden float requirement.
• Factor occasional branch services (cashier’s orders, amendments) into annual cost.

Choosing the right account for your business stage and spending pattern

Decide by modelling how a typical month and a tight month affect real cash and fees. Start by mapping your cash flows, currencies and integration needs before you compare product pages.

Best-fit scenarios for startups, SMEs and scaling companies

Startups usually favour flexibility: low held cash and S$0 opening rules, simple onboarding and free local transfers.

Established SMEs often prefer predictable monthly charges, local branch services and a fuller corporate bank ecosystem.

Scaling companies need multi‑currency features, strong integrations (Xero, QuickBooks, NetSuite) and fine-grained payment controls.

Decision checklist: minimum, features, integrations and transaction volume

• Trade off kept cash vs recurring monthly fees and fall‑below triggers.
• Compare per‑transfer costs against expected volume and FX frequency.
• Confirm required services: payroll, cards, approvals and accounting integration.
• Check opening requirements and promo expiry dates to avoid surprises.

Practical shortcuts for comparing options in the present market

Shortlist three contenders, model one normal month and one worst month, then total fees including waivers and FX spreads.

Tip: validate live promotions and integration tests before you commit — operational fit beats marketing claims.

What you typically need to open a corporate bank account in Singapore

Getting your paperwork ready halves onboarding time. Gather personal ID and company formation papers before you start the online form or visit a branch.

Common documents and KYC requirements

Most providers ask for proof of identity and proof of address for all signatories, directors and majority shareholders.

At company level you will usually supply the certificate of incorporation, share register or certificate of shareholding, the constitution (Memorandum & Articles) and, where needed, a board resolution.

Why both sets matter: personal documents confirm who controls funds; company papers show legal ownership and authorised signatories.

Online onboarding vs branch visits: what to expect

Many fintechs allow quick opening via document upload and a selfie. This route suits time‑poor founders and simple ownership structures.

Traditional corporate bank teams may ask for in‑person verification for complex shareholding, foreign directors or regulated industries. Wet‑ink signatures and due diligence visits still occur.

• Prepare consistent company names across all documents.
• Use current utility bills for address proof.
• Map your shareholding to a clear chart to avoid follow‑ups.

Opening friction is a real cost — the fastest account to open can be a strategic stopgap while you set up longer‑term services.

Conclusion

A pragmatic choice looks at 12 months of costs, not the headline opening requirements.

The core takeaway: pick the bank account that leaves the most usable cash after realistic monthly fees and FX or transfer charges are modelled.

OCBC vs UOB: weigh S$1,000 held cash against S$5,000 runway needs and waiver lengths.

DBS vs Airwallex vs Wise: compare monthly service fees and ADB waivers with fintech rails and FX spreads.

CIMB vs Maybank: note CIMB’s S$0 option with unlimited FAST/GIRO versus Maybank’s ADB trigger and regional remittance costs.

Action step: pick one primary account for day‑to‑day operations and add a specialist secondary for multi‑currency receipts or low‑cost transfers.

Final note: always confirm the latest published fee schedule and eligibility at the point of application, as providers can change pricing over time.
