The Small Details Matter
At FX-cient, we help clients develop treasury strategies from a big-picture perspective. However, some of the greatest savings often come from getting the small details right.
One question I am frequently asked is:
"What is the best way to convert foreign currency when travelling?"
The answer depends on several factors, but if we look solely at foreign exchange (FX) spread and transaction costs, the following ranking generally applies, from least expensive to most expensive. Some of the following ranking can shift due to currency pairing and jurisdictional difference, which are beyond the scope of this article.
Ranking Consumer FX Conversion Methods
Assuming you do not already have access to the foreign currency you need, here are some of the most common ways to obtain it, ranked from least expensive to most expensive.
1. Exchange Currency with a Trusted Friend
The most cost-effective option is often overlooked.
If you know someone with the opposite currency needs, both parties can exchange funds directly at or near the mid-market rate, avoiding bank and card network fees altogether. This assumes both parties are trusted individuals exchanging personal funds in compliance with applicable laws and reporting requirements. This is the lowest-cost method in theory, provided there are no AML, legal, regulatory, counterparty, or relationship concerns. Note that it is legal to swap currencies between individuals within the USA or Canada but illegal in some other jurisdictions. If the swap is between entities in the US and in Canada, it would best be avoided given strict regulations, tax implications and compliance risks.
2. Use a No-FX Fee Credit Card with cash back reward feature
Many travel-oriented credit cards eliminate additional foreign transaction fees.
Keep in mind that "no FX fee" does not mean the conversion occurs at the true interbank rate. Visa, Mastercard and other payment networks still apply their own currency conversion spread.
3. Use a No-FX-Fee Debit Card at Foreign ATM
Withdrawing cash with a no-FX-fee debit card often provides competitive FX rates.
4. Multi-currency digital wallets such as WISE or Revolut
Depending on withdrawal amount and ATM fees, multi-currency wallets such as Wise or Revolut may be comparable to, or slightly more expensive than, no-FX-fee credit and debit card solutions.
WISE uses mid-market rate with zero built-in margin. That said, there are transparent variable and fixed transaction fees.
5. Use a standard home bank Debit Card at Foreign ATM
Withdrawing cash with a standard home bank debit card converts the foreign currency with a smaller markup plus a marginal flat fee.
6. Convert Currency Through Your Home Bank
Banks generally offer competitive rates, especially for larger amounts, although spreads vary significantly by institution and jurisdiction. Foreign ATM withdrawals may sometimes be less expensive because local currency is sourced within the destination market rather than through a domestic bank branch network. The fact is that foreign currencies are always more expensive for your domestic bank to source and carry than the destination banks.
7. Pay in Local Currency with Visa, Mastercard or Diners Club
For most purchases, selecting the local currency and allowing your card network to handle the conversion is usually preferable.
USD-denominated American Express cards are generally comparable.
8. Non-USD American Express Cards May Incur Additional Conversion Costs
This is a lesser-known consideration.
For American Express cards whose billing currency is not USD (for example CAD, GBP, TWD and many others), transactions in certain foreign currencies may involve an additional conversion step compared with typical Visa or Mastercard processing. AMEX would convert the foreign currency transaction into USD first before converting to the AMEX card base currency. In an example of a CAD AMEX card, a EUR transaction would be converted to USD first before being converted to CAD.
9. Always Select the Local Currency at the Point of Sale
When a merchant asks whether you would like to pay in your home currency or the local currency, choose the local currency.
Choosing your home currency triggers Dynamic Currency Conversion (DCC), allowing the merchant's payment processor to perform the conversion. This commonly results in an additional markup that can be substantially higher than your card issuer's standard FX spread.
10. Airport Currency Exchange Kiosks
Airport kiosks are convenient but frequently among the most expensive options.
In many cases, their rates can be materially worse than bank or card-network conversion rates. Depending on the currency pairing, the cost is comparable to DCC noted in #9.
FX Cost Is Only Part of the Equation
The cheapest conversion method is not necessarily the best overall solution. Treasury decisions, whether personal or corporate, should balance both cost and risk.
Travellers for leisure should also consider:
The cost of converting unused foreign currency back into their home currency.
The risk of carrying large amounts of cash.
Acceptance of different card networks in destination countries.
Fraud protection and chargeback rights.
Travel insurance benefits associated with credit and charge cards.
Rental car, trip interruption and accident coverage available through card programmes.
The Corporate Perspective
For personal travel, the financial impact of FX optimization may amount to tens or hundreds of dollars.
For multinational businesses operating in multiple currencies (beyond business travelling), the stakes are significantly higher.
What might be a few thousand dollars of foreign-currency spending on credit cards can translate into millions of dollars of supplier payments, intercompany settlements or customer receipts.
The same principles apply, but the savings scale dramatically.
FX-cient frequently identifies opportunities that reduce conversion costs by approximately 2%. On a USD 50 million foreign-currency program, that could represent an additional USD 1 million in cash flow. The opportunity varies by program structure, currency pairs and current banking arrangements.
Why Human Expertise Still Matters in the Age of AI
AI is an extraordinary tool and will continue to improve.
Treasury decisions often require context, nuance and an understanding of how a specific business operates.
Large language models are trained on broad public information and common scenarios. They can provide good general guidance, but they cannot fully understand the unique priorities, risk tolerances and operating realities of every organization.
At FX-cient, we combine treasury expertise with business-specific insight to help clients maximize savings, minimize risk and make better-informed financial decisions.
In treasury, the details do not just matter — they compound.
