Most of a currency conversion's cost never shows up as a line item. FX payment solutions are the tools and providers that convert money between currencies as it moves, and the strongest options run on transparent FX with no opaque markup. Others bake their margin into the exchange rate, where it's hard to see and harder to compare.

In the World Bank's latest Remittance Prices Worldwide report, sending $200 cost an average of 6.36% globally, and 14.99% when sent through a bank. Part of that cost sits in the exchange rate rather than the fee.

Below: where FX markups hide, how timing and settlement currency shape what you pay, and what to look for in an FX partner.

What is an FX payment solution?

An FX payment solution converts funds from one currency to another as part of a payment, payout, or transfer.

Behind these conversions sits an enormous market. According to the Bank for International Settlements' 2025 Triennial Survey, FX trading averaged $9.6 trillion per day in April 2025, up 28% from 2022, with the US dollar on one side of 89% of all trades.

Businesses use them to accept pay-ins in other currencies, pay suppliers and workers abroad, send remittances, and repatriate international revenue.

Where do FX markups hide?

FX markups hide in the gap between the mid-market rate and the rate you're actually given. The mid-market rate is the midpoint between what buyers bid and sellers ask on the wholesale market. Many providers quote a rate away from it and call the transfer "fee-free."

Regulators have pushed for clearer disclosure. EU Regulation 2019/518 requires card-based currency conversion charges to be expressed as a percentage markup over the European Central Bank's euro reference rates, a useful benchmark for any provider.

How does dynamic currency conversion affect cost?

Dynamic currency conversion lets a cardholder pay in their home currency instead of the merchant's currency, usually at a less favorable rate.

Card networks require the choice to stay with the customer. Visa's DCC guidance says merchants "must not choose on your behalf" and must display the amount in both currencies, the exchange rate, and any fees or markup.

DCC can look like found revenue, but the pattern we see most often is that customers surprised by a conversion rate dispute the charge or don't come back. That trade-off matters even more in travel, where FX markups on travel payments shape how guests feel about the whole booking.

Cross-border charges also face more issuer scrutiny, one reason international travel bookings get declined so often.

Should you price in multiple currencies?

Pricing in local currency makes checkout familiar, but it moves the FX decision onto your side of the ledger. You decide the rate, how often prices update, and who absorbs swings.

1. Fixed local prices. You set prices per market and absorb FX movement. Simple for customers, riskier for margins.
2. Dynamic local prices. Prices update with exchange rates. Customers see prices move.
3. Single-currency pricing. You price in one currency and let the customer's issuer convert. Lowest effort, least control.

Corridor volume usually decides the mix. High-volume markets justify local pricing and multi-currency payment processing; long-tail markets often don't.

How do settlement currency and conversion timing change what you pay?

Your settlement currency and the moment a rate gets locked can matter as much as the markup itself. A rate fixed at checkout and settled in seconds carries very little market risk; one fixed days later carries all of it.

• Settlement currency. Settling in your operating currency simplifies accounting; multi-currency balances avoid converting twice.
• Rate lock timing. Locking at the time of sale matches what the customer saw; locking at settlement leaves you exposed to the market.
• Conversion point. Converting once, as close to the recipient as possible, avoids stacked margins from intermediaries.

Each correspondent hop adds time and potentially another conversion, and knowing how cross-border payments work end to end makes those steps easier to spot.

What hedging basics should platforms know?

Hedging protects a platform from exchange rate moves between the time it earns money in one currency and the time it spends it in another.

• Spot contracts convert at today's rate for immediate delivery.
• Forward contracts lock a rate today for a future date, useful for known payables like supplier invoices.
• Natural hedging matches revenue and costs in the same currency so swings offset each other.
• Netting offsets payables and receivables in a currency before converting only the difference.

Shorter exposure windows reduce how much hedging you need in the first place.

How does faster settlement reduce FX exposure?

Faster settlement shrinks the window in which exchange rates can move against you. Funds that settle in seconds leave little time for the rate to drift.

Slow settlement also ties up capital, since platforms end up pre-funding accounts in multiple currencies. Coinflow settles on a regulated, dollar-denominated settlement layer customers never see, then converts once at the last mile.

Progress industry-wide has been slow. The Financial Stability Board's 2025 G20 cross-border payments progress report found the average global cost of remittances has barely changed and that 2027 targets are unlikely to be met on schedule.

How do you evaluate FX payment solutions?

Evaluate FX payment solutions on rate transparency first, then speed, coverage, and integration effort. A low headline fee means little if the rate carries a wide spread.

1. Rate transparency. Can the provider show its markup over mid-market per transaction?
2. Rate lock timing. Is the rate fixed at the time of sale or at settlement?
3. Corridor coverage. Does it support local rails in the countries you pay into?
4. Settlement speed. Seconds, same day, or multiple business days?
5. Compliance. Are sanctions screening and cross-border payments regulations handled for each corridor?
6. Integration. One API across pay-ins and payouts, or separate vendors per region?

How does Coinflow handle FX payments?

Coinflow is payments infrastructure that gives businesses one connection to every payment network, with transparent FX and no opaque markup. Cards, Apple Pay, Google Pay, ACH, SEPA, PIX, and more run through one API, with pay-ins in 160+ countries and instant payouts in 40+ countries.

Settlement happens at T+5 seconds, 24/7/365, weekends included, so rates don't drift while funds sit in transit. Instant payouts run on real-time payments (RTP), Push to Card, SEPA Instant, UK Faster Payments, and PIX. Merchants typically see 20–35% lower acceptance costs.

For remittance companies and other cross-border platforms, that means fewer conversion steps, less pre-funded capital, and real-time status on every payment. Know Your Customer (KYC), anti-money laundering (AML), and sanctions screening are built in. Integration is typically live in weeks, not quarters.

If you're comparing cross-border payment solutions, we'll map your current conversion costs corridor by corridor.

A rate you can check against mid-market protects your margins more than a low headline fee, so get the markup in writing from any FX partner you shortlist.
