Currency exchange Singapore: A complete guide for businesses (2026)

Key takeaways:

• Singapore is the world's third largest foreign exchange centre, but most businesses are still paying more than they need to through hidden markups and transfer fees.

• Every currency exchange method adds a margin on top of the interbank rate: the real cost is that margin plus any transfer fees combined.

• Airwallex lets businesses convert at 0.4% to 0.6% above interbank, saving you up to 80% on FX fees as compared to traditional banks. You also get free transfers to 120+ countries via local payment rails.

Currency exchange in Singapore is competitive by global standards. The city-state ranks as the world's third largest foreign exchange (FX) centre, with average daily trading volumes of US$1.485 trillion as of April 2025.¹

This guide covers how currency exchange works in Singapore, which methods are available to businesses, what each one actually costs, and how to reduce FX fees as your cross-border payment volumes grow.

How currency exchange works in Singapore

When you exchange currency in Singapore, the rate you receive is never quite the rate you see on Google.

That figure on Google (known as the interbank rate, or mid-market rate) is the wholesale rate that banks use when trading currencies with each other. It is the true value of a currency before anyone takes a cut.

Most providers add a margin on top of that rate to cover their costs. That margin is called a spread, and it is how most money changers and banks make their money on currency exchange. On top of the spread, some providers also charge a flat fee per transaction.

The real cost of any currency exchange is the spread plus the transfer fee combined.

A provider advertising zero transfer fees may still have a wide spread built into the rate, meaning you pay more without realising it. Checking both figures before you transact is the only way to compare providers fairly.

Currency exchange options in Singapore

Singapore businesses have three main options for exchanging currency: licensed money changers, banks, and digital multi-currency platforms. Here’s a quick overview:

Option 1: Licensed money changers

Money changers offer competitive rates for cash exchanges, particularly at high-traffic hubs like The Arcade at Raffles Place and People's Park Complex in Chinatown, where competition between counters keeps spreads tight.

There are no transfer fees. The limitation for businesses is scale: money changers deal in physical cash, which is impractical for regular supplier payments, payroll, or invoice settlement.

Option 2: Banks

Banks are the default for most Singapore businesses making international transfers. They are familiar and offer the full suite of business banking services alongside FX.

The trade-off is cost: banks typically embed a 1–2% markup into the rate they quote you, and telegraphic transfers via SWIFT attract flat fees of S$10–S$40 per transaction,³ plus potential correspondent bank deductions in transit.

Option 3: Digital multi-currency platforms

Fintech platforms offer the tightest spreads and the lowest transfer fees of the three options. Providers publish their FX margins upfront (typically well under 1% above the interbank rate) rather than embedding them in an opaque quoted rate.

For example, Airwallex converts currencies at 0.4% above the interbank rate for major currencies and 0.6% for all other currencies. This saves you up to 80% on FX fees compared with traditional banks.

How much does currency exchange cost in Singapore?

The real cost of currency exchange is rarely the figure advertised. To understand what you are actually paying, you need to combine the spread with any transfer fees.

The example below shows how the three methods compare on a single S$10,000 conversion to US dollars, using an indicative interbank rate of S$1 = US$0.76.

Figures are illustrative. Actual rates and fees vary by provider and transaction date.

Note that the gap widens as transaction size and frequency increase.

A business making S$50,000 in monthly supplier payments at a bank's 1.5% spread pays roughly S$9,000 per year on transfer fees. If you’re using a fintech with a 0.5% spread, you’ll pay S$3,000, giving you S$6,000 of savings.

One additional cost to watch for is dynamic currency conversion (DCC). This applies when you or your team use a card overseas and are offered the option to pay in Singapore dollars instead of the local currency.

DCC typically comes with a poor exchange rate and hidden markups. Always choose to be charged in the local currency to avoid it.

Where to exchange currency in Singapore

For one-off or cash needs, licensed money changers remain a practical option.

Competitive hubs like The Arcade at Raffles Place and People's Park Complex in Chinatown tend to offer tighter spreads than airport or hotel counters, where rates are typically worse due to lower competition and captive demand.

How businesses can reduce FX costs in Singapore

The biggest FX savings for businesses come not from finding a slightly better rate on any single transaction, but from changing how you structure your payments altogether. Here are the most effective steps to take:

1. Check the all-in cost, not just the headline rate

Before sending any payment, compare the offered exchange rate against the interbank rate and add any transfer fees on top.

A provider advertising zero transfer fees may still have a wide spread built into the rate. The only number that matters is how much your recipient receives.

2. Hold foreign currencies rather than converting immediately

If your business regularly receives payments in USD or EUR, holding those balances in a multi-currency account means you avoid converting back to Singapore dollars and then converting again when you need to pay a foreign supplier.

Each unnecessary conversion costs you the spread twice.

3. Match incoming and outgoing currencies

Where possible, pay in the same currency you collect.

A Singapore business that invoices US clients in USD can use that balance to pay US-based SaaS subscriptions, Google or Meta ad spend, or Chinese suppliers quoting in US dollars without converting back to Singapore dollars first.

Every conversion you avoid is an FX cost that you save on.

4. Use local payment rails instead of SWIFT

SWIFT transfers attract flat fees and can involve deductions from intermediary banks in transit. Providers that route payments via local rails in the destination country — such as ACH in the US or SEPA in Europe — are faster and cheaper for most corridors.

5. Consolidate payments into batches

If you are paying multiple overseas suppliers, consolidating into a single batch transfer reduces per-transaction overhead and makes reconciliation easier for your finance team.

Frequently asked questions (FAQs)

Where is the best place to exchange currency in Singapore?

It depends on what you need the currency for. For cash exchanges, licensed money changers at competitive hubs like The Arcade at Raffles Place and People's Park Complex tend to offer tighter spreads than banks or airport counters. For business payments, a fintech platform like Airwallex gives you better rates, lower fees, and the ability to send funds directly without handling cash.

How much does currency exchange cost in Singapore?

The cost depends on the method and provider. Money changers typically add a spread of 0.5–1.5% above the interbank rate with no transfer fees. Banks add a spread of around 1–2% and charge S$10–S$40 per telegraphic transfer. Digital platforms generally offer spreads well under 1%; Airwallex, for example, charges 0.4% to 0.6% above interbank, saving you up to 80% on FX fees compared to traditional banks.

Is it better to use a bank or a money changer for business payments in Singapore?

For one-off cash needs, a money changer at a competitive hub is usually cheaper than a bank. For regular international payments, neither is ideal. Banks are expensive at scale and money changers are not set up for digital transfers. A digital multi-currency platform is better suited to businesses making frequent cross-border payments.

What is the interbank exchange rate and why does it matter for businesses?

The interbank rate is the rate at which banks trade currencies with each other. It is the baseline before any provider adds their margin. Checking the interbank rate before any transaction lets you see exactly how much markup you are paying — and compare providers fairly.

How can my business avoid hidden FX fees in Singapore?

Compare the offered rate against the interbank rate before transacting. Look for providers that publish their FX margin upfront rather than embedding it in a quoted rate. Holding foreign currency balances in a multi-currency account also helps you avoid unnecessary conversions and the fees that come with them. Airwallex shows the full cost before you confirm any transaction.

Is Airwallex licensed to operate in Singapore?

Yes. Airwallex (Singapore) Pte. Ltd. is licensed by the Monetary Authority of Singapore (MAS) as a Major Payment Institution under the Payment Services Act 2019. You can verify this on the MAS website.
