Key takeaways
An FX markup fee is a percentage added on top of the mid-market exchange rate whenever you pay in a foreign currency. It's separate from, and often larger than, the transaction fee you see on your statement.
Banks and traditional corporate cards typically charge between 1.5% and 3% per foreign currency transaction on top of any other service fees.
For businesses that import regularly, whether from Alibaba, Korean beauty suppliers, or Japanese equipment manufacturers, this fee compounds quickly into a significant annual cost.
Choosing payment tools with low or zero FX markup, such as a corporate card with preferential exchange rates, can materially reduce your cost base.
The fee you probably aren't tracking
You placed a supplier order on Alibaba last Tuesday. The USD amount looked fine. Then the charge hit your account and something felt off. After checking, you realised the HKD equivalent was higher than expected, but you shrugged and moved on.
A large portion of the gap between what you expected to pay and what you actually paid is almost certainly an FX markup fee. While some may mistake it for a scam, it's actually standard banking practice. However, most merchants don't track it, and that silence can be expensive.
This article explains what an FX markup fee is, how it stacks up across different payment methods, and what businesses that import regularly can do to stop overpaying.
What is an FX markup fee?
When you pay for something in a foreign currency, such as in USD on Alibaba or JPY to a Japanese equipment supplier, your bank converts the amount to HKD using an exchange rate. The problem is that the rate your bank applies is almost never the real mid-market rate.
Instead, your bank adds a margin on top of that rate. That margin is the FX markup fee.
How it works in practice:
The mid-market USD/HKD rate is, for example, 7.78
Your bank applies a rate of 7.94
That difference of roughly 2% is the FX markup
However, it doesn't always appear as a line item. Often, it's embedded silently in the conversion rate itself
The result: you're paying more than the actual exchange rate every single time you transact in a foreign currency, and in many cases, you won't see it itemised on your statement.
FX markup fee vs foreign transaction fee: What's the difference?
These two terms are often used interchangeably, but they describe different charges:
Fee type
What it is
Typical range
FX markup fee
A margin added to the mid-market rate
1%–3%
Foreign transaction fee
A flat percentage charged per overseas transaction
1%–2%
Cross-border fee
A network-level charge (Visa/Mastercard) passed on to the merchant
0.4%–1%
In practice, many banks bundle these together or use one term to describe all charges related to foreign currency payments. What matters for your business is the total cost of conversion — how much are you paying above the mid-market rate, all in?
How much are banks and cards actually charging?
Rates tend to vary widely. Here's a general picture of what businesses typically encounter:
Traditional bank corporate cards: FX markup of 1.5%–3%, sometimes with an additional foreign transaction fee of 1%–1.5% on top
Consumer credit cards used for business: Similar markup range, plus potential cash advance fees if used for supplier payments
Fintech and neobank business cards: Often lower markups, with some providers offering rates close to mid-market
Wire transfers (TT payments): Banks typically apply a markup on the conversion rate plus a fixed transfer fee, often HK$100–HK$300 per transaction
Note: Exact rates vary by bank, card type, and account tier. Always check your card's terms or contact your bank directly to understand the full cost of foreign currency payments.
What this means for businesses that import regularly
The FX markup fee is a background cost that most businesses don't track as a line item, but for anyone importing stock or materials regularly, it can compound quickly.
Sourcing from Alibaba or overseas manufacturers
Hong Kong retailers and e-commerce merchants sourcing from Alibaba, Made-in-China, or directly from Mainland factories are typically paying in USD or RMB. If you're spending HK$200,000 per month on overseas stock and your card carries a 2% FX markup, that's HK$4,000 per month, and HK$48,000 per year, going silently to your bank before a single item hits your shelf.
Beauty industry: Korean and Japanese ingredient imports
Many businesses in the beauty and wellness sector in Hong Kong often rely on Korean and Japanese imports, from actives and packaging to professional tools and equipment. K-beauty distributors and Japanese professional equipment suppliers commonly invoice in KRW or JPY, two currencies where exchange rate volatility adds another layer of cost on top of the standard FX markup.
A salon or skincare retailer placing monthly orders worth HK$80,000 in KRW could be paying HK$1,200–HK$2,400 per month in FX fees alone, depending on their card's markup rate. Over a year, that's the equivalent of a month's ingredient budget.
The hidden compounding effect
The fee isn't just on the order total. If your supplier invoices in USD and you pay by credit card, you may encounter:
The FX markup on conversion
A foreign transaction fee on the card
A cross-border network fee from Visa or Mastercard
Potential late payment interest if cash flow is tight
None of these will necessarily be flagged separately, but they will make your supplier payments cost more than your quotes suggested.
How to calculate what FX markup fees are costing you
Here's how to do a rough calculation:
Add up your total monthly spend on foreign currency payments (supplier orders, overseas SaaS tools, international shipping, etc.)
Find your card or bank's FX markup rate (check the terms or ask your relationship manager)
That's a material operating cost, and one that doesn't show up in your P&L as "FX fees." It hides in your cost of goods.
What to look for in a lower-cost alternative
Not all payment tools are equal when it comes to FX. When evaluating options, look for:
Markup rate vs mid-market rate: The smaller the gap, the better. Some providers advertise "no foreign transaction fee" but still apply a markup on the rate itself, which is why it's important to check the all-in rate.
Transparency: Can you see the exchange rate applied before you approve the transaction?
Currency coverage: Does the card support the currencies your suppliers use — USD, CNY, JPY, KRW, EUR, GBP?
Spending controls and reconciliation: For businesses with multiple buyers or departments, can you set limits and pull clean transaction records for accounting?
FAQs
Is the FX markup fee the same as a foreign transaction fee?
Not exactly. The FX markup is embedded in the exchange rate itself; it's the difference between the mid-market rate and the rate your bank applies. A foreign transaction fee is an additional percentage charged separately. Some cards charge both; others charge only one.
Do all credit cards charge an FX markup?
Most traditional bank cards do, although the rate tends to vary. Some fintech and business payment cards offer lower markups or a rate closer to mid-market. It's good practice to always check the card's full fee schedule, instead of just checking the headline rate.
Can I avoid FX markup fees entirely?
It's difficult to eliminate them entirely, but you can reduce them significantly by choosing payment tools with lower markups and avoiding high-fee cards for overseas spend. Paying suppliers via local currency accounts (where possible) can also help.
How do I find out what FX markup my current card charges?
Check the fee schedule in your card agreement, or call your bank and ask specifically: "What exchange rate markup do you apply to foreign currency transactions?" Some banks quote this clearly, while others bury it in their terms.
Does the FX markup apply to online purchases too?
Yes. Any transaction processed in a foreign currency, whether in-store overseas or online with an international merchant, will typically trigger the FX markup.
The bottom line
The FX markup fee isn't complicated, but it is easy to ignore. For businesses that import regularly, whether from Chinese manufacturers, Korean beauty suppliers, or Japanese professional equipment brands, it's a cost that accumulates silently in your cost of goods.
Tracking it, understanding it, and choosing the right payment tools for overseas spend is one of the more straightforward ways to improve your margins without changing what you buy or who you buy from.
