Foreign transaction fees in Singapore: How they work (2026)

Key Takeaways:

• Foreign transaction fees are charges applied every time you pay in a currency other than SGD. On most Singapore cards, these reach up to 3.25%¹ per transaction.

• Each payment can carry multiple fee layers: a card network charge, a bank admin fee, and sometimes a dynamic currency conversion (DCC) markup on top.

• With a multi-currency corporate card like the Airwallex Corporate Card, you can pay directly from the currency you hold and avoid conversion fees altogether.

Foreign transaction fees are charges you pay every time you spend or send money in a foreign currency. For most Singapore businesses, they're a regular cost of operating internationally. But many business owners don't know exactly what they're paying or why.

This guide breaks down how foreign transaction fees work, what each layer costs, and what mistakes to avoid.

What are foreign transaction fees?

A foreign transaction fee is a charge applied whenever you pay in a currency other than your own. In Singapore, most banks add this fee to card payments made overseas or with international merchants online.

The fee is not one single charge; it is a combination of fees from different parties, including a card network fee and bank admin fee.

Card network fee

Visa and Mastercard each impose a currency conversion charge of 1%¹ on foreign transactions. This fee is applied on top of the exchange rate they use to convert your payment.

Bank admin fee

Your card-issuing bank adds its own administrative fee on top of the network charge. For major Singapore banks, this is 2.25%¹ of the transaction amount.

Together, these two charges make up the standard 3.25%¹ total you see on most Singapore card statements.

What about dynamic currency conversion?

Dynamic currency conversion (DCC) is a separate scenario. It occurs when an overseas merchant or ATM offers to convert your payment into SGD at the point of sale, rather than letting your card handle the conversion.

DCC sounds convenient — you see the charge in SGD immediately. But the merchant sets the exchange rate, and it is almost always less favourable than the rate your bank would apply. On top of that, additional charges from the merchant or their payment provider may apply.

The simple rule: always pay in the local currency when you are overseas. Let your card handle the conversion.

How do foreign transaction fees affect your business?

For businesses that make regular international payments, foreign transaction fees are a recurring operating cost. Here is where they tend to hit hardest.

Higher costs on every international payment

Every overseas payment your business makes carries the fee. That includes paying suppliers in China, subscribing to US-based software, running ad campaigns on global platforms, or booking travel for your team.

At 3.25%¹, a business spending S$20,000 a month on international transactions pays over S$600 in fees alone — before accounting for exchange rate markups.

Unpredictable exchange rates

Foreign transaction fees do not operate in isolation. The exchange rate your card network applies also shifts between the time you make a payment and when it settles. This makes it harder to forecast international costs accurately, particularly for businesses with recurring overseas expenses.

Hidden costs from double conversion

Most Singapore cards convert foreign currencies to USD first, then to SGD. This means two conversions happen on a single transaction, and each one carries the network's exchange rate spread on top of the stated fees.

If your business pays in currencies like JPY, EUR, or HKD, this double conversion can set you back a fair bit.

Complex expense management

When fees vary by transaction type, currency, and card, reconciling international expenses becomes harder. Teams travelling overseas, paying multiple vendors, or managing ad spend across currencies face inconsistent charges that are difficult to predict or categorise accurately.

How foreign transaction fees are calculated

Most foreign transaction fees are percentage-based, so the larger the payment, the more you pay. Understanding how each fee layer applies helps you see exactly what ends up on your statement.

Here are two examples using a business hotel payment in Hong Kong.

Example 1: Paying in the local currency (without DCC)

You travel to Hong Kong and pay HK$1,200 for a hotel stay at the front desk. You pay in HKD and let your card handle the conversion.

Here is how the fees apply:

This is the standard scenario for most overseas card payments on a Singapore Visa or Mastercard.

Example 2: Paying in SGD via dynamic currency conversion (with DCC)

You book the same hotel online and the payment terminal offers to charge you in SGD rather than HKD. You accept.

When you choose DCC, the merchant — not your bank — sets the exchange rate. That rate is almost always less favourable than what your card network would apply. Your bank then adds its own charges on top.

Here is how the fees apply for a debit card in a DCC transaction:

Note: for credit cards in a DCC transaction, the bank charge in step 3 is 1% rather than 2.8%, giving a total verified charge of 2%¹ — but the merchant's exchange rate markup is added on top of this, and it varies.

The key point is that the rate the merchant applies is almost always worse than what your bank would have applied in a standard transaction, meaning DCC typically costs more overall regardless of card type.

The takeaway: Paying in the local currency and letting your card handle the conversion will almost always cost less than accepting DCC.

Foreign transaction fees by bank in Singapore

The total foreign transaction fee you pay depends on your bank; every major Singapore bank charges a slightly different combination of network and administrative fees.

The table below shows the standard foreign transaction fee at the five largest card-issuing banks in Singapore:

The information in this table has been reviewed to be accurate as of 28 April 2026.

Notes on this table:

• Figures are for standard Visa/Mastercard credit and debit card payments made in a foreign currency

• HSBC's 2.5% figure applies to debit card transactions; credit card fees are not explicitly stated on HSBC's official fee page as a single total

• Standard Chartered's 3.5% applies to credit card foreign currency transactions; debit card overseas fees are also stated as up to 3.5%⁵

• These are standard rates; certain cards (e.g. travel cards) may carry different rates

Common foreign transaction fee mistakes to avoid

Most foreign transaction fees are avoidable (or at least reducible). These are the four mistakes that cost Singapore businesses the most:

Mistake 1: Accepting dynamic currency conversion

When an overseas terminal offers to charge you in SGD, it feels straightforward.

But as shown in the examples above, DCC means the merchant sets the exchange rate — and it is almost always less favourable than what your bank would apply. Always choose to pay in the local currency and let your card handle the conversion.

Mistake 2: Not checking your card's fee before you pay

Not all cards carry the same foreign transaction fee. Standard Chartered charges 3.5%⁵, while HSBC charges up to 2.5%⁴ — that makes a meaningful difference on large transactions.

Check the fee schedule for every card your team uses before assuming the rate is the same across the board.

Mistake 3: Using the wrong currency wallet on a multi-currency card

If your business holds a multi-currency card or account with balances in multiple currencies, always pay from the matching currency wallet.

Paying in USD from your USD balance incurs no conversion. Paying in USD from your SGD balance triggers a conversion — and the associated fees. This is a common oversight when teams manage spend across multiple currencies.

Mistake 4: Taking "no foreign transaction fee" claims at face value

Some card providers advertise zero foreign transaction fees. Read the fine print before assuming this applies to all transactions.

Some cards waive the bank admin fee but still pass on the card network charge. Others cap the waiver at a monthly spend limit or restrict it to specific currencies.

Confirm exactly which fees are waived, under what conditions, and whether the exchange rate applied carries a hidden spread.

How to reduce foreign transaction fees

Reducing foreign transaction fees comes down to two things: using the right card for international payments, and avoiding unnecessary currency conversions.

The most effective options include holding balances in foreign currencies so you pay without converting, using a card with no or low foreign transaction fees, and switching recurring international payments to bank transfers or local payment rails where possible.

Frequently asked questions (FAQs)

Is 3.25% a high foreign transaction fee?

For Singapore cards, 3.25% is the standard rate charged by most major banks. It may seem small on a single transaction, but it adds up fast for businesses making regular international payments. On S$50,000 of annual overseas spend, that is S$1,625 in fees alone — not including exchange rate markups.

What is the difference between a foreign transaction fee and a currency conversion fee?

A foreign transaction fee is a charge your bank adds for processing a payment in a foreign currency — it appears as a percentage on your statement. A currency conversion fee is a markup built into the exchange rate itself, applied by your card network when converting currencies. Both can apply to the same transaction, meaning you may be paying more than the stated fee percentage suggests.

Does paying in SGD overseas help me avoid foreign transaction fees?

No, it actually makes things worse. When you choose to pay in SGD at an overseas terminal, this triggers dynamic currency conversion (DCC). The merchant sets the exchange rate, which is typically less favourable than what your bank would apply. Your bank may also add additional charges on top. You are almost always better off paying in the local currency.

Do foreign transaction fees apply to online purchases from overseas merchants?

Yes, foreign transaction fees apply any time your card processes a payment in a foreign currency — whether you are physically overseas or shopping online from a Singapore-based device. If the merchant is based outside Singapore and bills in a foreign currency, the fee applies. This includes international software subscriptions, overseas supplier invoices, and global ad platforms.

Does Visa or Mastercard charge foreign transaction fees directly?

Both Visa and Mastercard charge a currency conversion fee of 1%¹ on foreign transactions. This is the network component of the total foreign transaction fee. Your bank then adds its own administrative fee on top — typically 2.25%¹ for major Singapore banks — bringing the combined total to 3.25%¹. The network fee alone does not cover the full amount you see on your statement.

How do I know if my card has a foreign transaction fee?

Check your card's terms and conditions document or your bank's official fee schedule. Look for terms like "foreign currency transaction fee", "overseas transaction fee", or "FX fee". Most Singapore banks publish these on their support pages. If you want to avoid the fee entirely, Airwallex Corporate Cards let you pay directly from the currency you hold, with no foreign transaction fee applied.
