    Many SMEs maintain substantial cash balances to cover payroll, supplier payments and unexpected expenses. The challenge is that these funds can sit idle for weeks or months, earning little to no return while inflation erodes its value.

    Interest-bearing business accounts solve this by turning everyday balances into a low-effort source of extra income, and without locking in funds or compromising liquidity.

    Traditional current accounts provide transactional flexibility but pay no interest. Interest-bearing business accounts combine full banking functionality with earnings on idle cash.

    How do interest-bearing business accounts work?

    Interest-bearing business accounts enable businesses to earn returns on eligible account balances. Depending on the account structure, interest rates, eligibility requirements and access to funds may vary.

    For businesses, these accounts can offer a way to generate additional income from cash that may otherwise remain idle while still supporting broader cash management objectives. They can be particularly relevant for businesses that maintain working capital buffers, hold funds for upcoming expenses, or experience fluctuating cash flow throughout the year.

    OCBC’s Business Growth Account* and Multi-Currency Business Account allow eligible businesses to opt in to earn interest on qualifying balances via the interest rate promotion^. With tiered rates, daily calculation, and monthly crediting, these interest-bearing business accounts deliver practical financial outcomes: higher cash reserves, reduced borrowing costs, improved profitability, and stronger resilience for growth.

    OCBC Business Growth Account

    OCBC’s Business Growth Account features a straightforward tiered interest structure, available to customers who opt in to the interest rate promotion^ either during or after account opening (rates as of the current promotion, subject to T&Cs). :

    ●    First S$50,000: 0%
    ●    Next S$100,000 (S$50,001 to S$150,000): 0.30% p.a.
    ●    Balances above S$150,000 (up to S$1 million cap): 0.50% p.a.

    Interest is calculated daily and credited monthly. There is no lock-in and funds remain fully accessible for payroll, supplier payments, or investments.

    Example calculation (illustrative):

    Assuming a consistent daily end-of-day balance of S$250,000 throughout the year:

    ●    First S$50k: S$0
    ●    Next S$100k at 0.30%: ~S$300/year
    ●    Remaining S$100k at 0.50%: ~S$500/year 

    Total estimated annual interest: ~S$800

    Interest is calculated daily based on end‑of‑day balances and credited monthly. Actual interest earned may vary depending on daily balance fluctuations.

    OCBC Multi-Currency Business Account 

    The Multi‑Currency Business Account offers similar benefits for USD holdings, with tiered interest rates available to customers who opt in to the interest rate promotion^, whether at the point of account opening or after the account has been opened (rates as of the current promotion, subject to T&Cs):

    ●    First US$150,000: 0%
    ●    Next US$350,000 (up to US$500,000): 0.50% p.a.
    ●    Above US$500,000 (up to US$1 million): 0.80% p.a.

    Businesses can open the Multi-Currency Account alongside the SGD account at no extra setup fee, making it ideal for importers, exporters, or companies receiving foreign payments.

    How idle cash can turn into real earnings

    The core value of an interest-bearing business account is simple: make your cash work harder without taking on risk or sacrificing control.

    Instead of letting surplus funds sit idle between payroll cycles, project payments, or seasonal peaks, businesses earn passive returns. Over time, this compounding effect builds meaningful reserves. For a solopreneur or early-stage startup with S$80,000–S$150,000 in average balances, the 0.30% tier already generates useful extra income. Scaling businesses with higher balances access the 0.50% (SGD) or 0.80% (USD) tiers for greater impact.

    Key financial advantages include:

    ●    Direct boost to profitability: Interest earned is pure additional revenue.
    ●    Full liquidity with no lock‑in or penalty: Funds remain accessible for day‑to‑day business needs whenever required.
    ●    One consolidated account: Earn interest while using the same account for daily transactions, without needing to maintain separate accounts for spending and savings.
    ●    Inflation hedge: Even modest rates help offset rising costs in Singapore’s economy.

    Unlike fixed deposits, these accounts maintain full liquidity. Need funds for an unexpected opportunity or expense? Transfer them instantly via FAST, GIRO, or the OCBC Business app.

    Choosing the right interest-bearing business account

    Tips for selecting business accounts:

    ●    Expected average balances and currency needs
    ●    Transaction volume (OCBC offers 80 free GIRO and 80 free FAST transactions a month)

    ●    Overall ecosystem value (debit card, payments, insurance perks)

    OCBC’s solution is suitable for growth-oriented SMEs due to low entry barriers, strong digital business banking experience via OCBC Velocity and seamless SGD and foreign currency account integration.

    Optimisation tips:

    ●    Opt in for interest rate promotion during application^.
    ●    Monitor balances to stay above key tiers.
    ●    Pair SGD and USD accounts for natural hedging.
    ●    Use app alerts to monitor cash flow.

    FAQS
    Common questions
    What is the minimum balance needed to start earning interest with OCBC?

    With the Business Growth Account, interest is earned only if you opt in to the interest rate promotion. Under this promotion, interest begins on balances above S$50,000, with the first S$50,000 earning 0%. For USD balances, the Multi-Currency Business Account also requires opting in to the promotion, and interest starts on amounts above US$150,000.

    When you opt in, a higher minimum balance requirement applies, and a fall‑below fee may be charged (S$50 for SGD accounts / US$50 for USD accounts) if the required monthly average balance is not maintained.

    Can I opt in to earn interest on both the Business Growth Account and the Multi-Currency Business Account?

    Yes. Both accounts can be opened simultaneously at no additional setup fee, making it straightforward for businesses with both SGD and USD cash flows to earn interest across both currencies from a single banking relationship.

    How is interest calculated and when will I see it in my account?

    Interest accrues daily based on your end-of-day balance and is credited to your account monthly. As interest is calculated daily, even short-term balance increases contribute, you don't need to maintain a high balance for the entire month to benefit.

    Will I lose access to my funds once I opt in to earn interest?

    No. Unlike fixed deposits, there is no lock-in period on either the OCBC Business Growth Account or OCBC Multi-Currency Business Account. Funds remain fully accessible at all times, you can transfer or spend as normal without any penalty or delay.

    Is the interest rate promotion suitable for a business that's just starting out?

    It can be, depending on your cash position. The interest rate promotion is most beneficial if your average balance regularly exceeds S$50,000. However, early-stage businesses with lower balances can still open a Business Growth Account or Multi-Currency Account without opting into the promotion initially. This allows you to start managing your finances and transactions first, and opt in to the interest rate promotion later when your balances grow to a level where you can benefit from earning interest.
