Why Your Bank Charges More Than the Exchange Rate Says (and How to Avoid It)

Your bank statement shows a $0 wire fee. Your supplier in Shanghai or São Paulo still receives 2–3% less than the rate you saw quoted online the morning you sent the payment. No line item explains the difference, because the difference was never in a line item, it was built into the rate itself before the transfer left your account.

The trick is in the rate, not the fee

Most CFOs and treasurers checking international payment costs look for the wrong thing: a transfer fee, a wire charge, a "commission" field on a statement. Banks know this, which is why the visible fee is often small or advertised as $0. The actual margin sits in the exchange rate the bank applies to convert your currency, and it's almost never disclosed as a percentage next to the transaction.

Here's how it works. On the morning you initiate a $100,000 payment, the mid-market rate — the one you'd see on Reuters or XE.com is public and identical for everyone. Your bank does not use that rate. It applies its own, adjusted rate, typically 1–3% worse than the mid-market rate. On a $100,000 payment, that gap alone is between $1,000 and $3,000 money your company loses before any wire fee is even applied. The bank doesn't need to itemize it, because from an accounting standpoint, it isn't a fee. It's just "the rate."

This is not unique to one bank or one corridor. It's structurally how correspondent banking prices FX for corporate clients, and it scales with volume: a company making dozens of international payments a month is repeating this loss every time, usually without a clean way to measure it against the real market rate.

Why traditional banking makes this hard to see and harder to fix

The opacity isn't accidental; it's a byproduct of how cross-border payments are built. A payment routed through correspondent banking can pass through one, two, or three intermediary banks before it reaches the recipient, and each one can apply its own small deduction along the way. None of those deductions show up on your outgoing wire confirmation they surface only when your supplier reports receiving less than expected.

Regulators have flagged this as a systemic gap, not just a customer-service annoyance. A 2025 Financial Stability Board progress report on the G20's cross-border payments roadmap found that B2B payment transparency the share of providers actually disclosing cost and speed to end users before a transaction sits at just over a third, well below other payment categories. In other words, the businesses moving the most money internationally are, structurally, the ones with the least visibility into what it actually costs them.

Comparing rates after the fact doesn't fix the underlying problem either. By the time your finance team reconciles what your supplier received against what you sent, the payment has already settled there's no way to renegotiate a rate that's already been applied.

How Linka removes the spread instead of trying to shrink it

Linka enables B2B companies to settle international payments in under 24 hours using stablecoin infrastructure (USDC/USDT), with fully transparent costs a commission between 2% and 6% depending on volume, and no hidden FX spread layered on top of that number.

The structural difference is where the margin lives. Instead of routing your payment through a chain of correspondent banks that each apply an undisclosed markup, Linka settles the transaction on stablecoin rails and charges a single, disclosed commission up front. There is no second number hiding inside the exchange rate the commission you're quoted is the cost you pay, and it's the only cost. Settlement also happens in under 24 hours, which removes the additional risk of rate movement during a multi-day SWIFT transfer a real cost for companies with fixed-price supplier contracts negotiated months in advance.

This doesn't make Linka free Linka is not "sin intermediarios," it is a transparent one. What it removes is the guesswork: a treasurer can calculate the exact cost of a payment before sending it, compare that number against the mid-market rate, and know that figure won't move once the transaction is confirmed.

What the data says about the size of the problem

Three data points are worth putting in front of your CFO:

1. Bank FX markups on cross-border transfers typically run 1–3% above the mid-market rate, adding $1,000–$3,000 in invisible cost on every $100,000 payment before any wire fee (Cobo, Cross-Border Transactions: Global Payments Guide, 2026).
2. In the Financial Stability Board's 2025 monitoring of the G20 cross-border payments roadmap, P2P payments originating from Latin America and the Caribbean were among the segments farthest from the retail cost target, roughly four percentage points off pace (FSB, Consolidated Progress Report, October 2025).
3. The G20's own target retail cross-border payment costs below 1%, with no corridor above 3% was set for 2027, and a December 2025 BIS assessment concluded the industry is unlikely to hit that deadline on current trajectory (Bank for International Settlements, December 2025).

None of these numbers are Linka's estimates. They come from payments-industry analysis and the regulators tracking the problem directly, and they point to the same conclusion: the spread is not shrinking on its own.

FAQ

Why doesn't my bank show the FX spread as a separate fee? Because accounting-wise, it isn't classified as a fee it's the exchange rate the bank chooses to apply. Banks are not required in most jurisdictions to disclose that rate as a percentage above the mid-market rate, so it appears simply as "the rate," not as a cost line.

How can I calculate the real spread my bank is charging? Compare the rate your bank applied on a completed transfer against the mid-market rate published by a source like Reuters or XE.com at the time you sent the payment. The percentage difference between the two, multiplied by your transfer amount, is your hidden cost.

Does a "$0 wire fee" bank account mean international payments are free? No. A $0 advertised wire fee typically means the bank recovers its margin entirely through the exchange rate spread instead of a visible charge the cost still exists, it's just not itemized.

How is Linka's commission different from a bank's FX spread? Linka's commission (2%–6% depending on volume) is the entire cost, disclosed before you send the payment. There is no additional markup hidden inside the exchange rate on top of that commission.

Does settlement speed actually affect cost, or just convenience? It affects cost directly for companies with fixed-price contracts. A payment that takes several days to settle exposes your company to currency movement during that window a real, if variable, cost on top of any spread.

Is this only a problem for large payments? No, the spread is percentage-based, so it applies proportionally regardless of size. It becomes more material in absolute dollar terms as payment volume grows, which is why it matters most to companies making recurring international payments.

The first step is measuring your own spread

If your treasury is still absorbing hidden FX costs on international payments, the first step isn't switching providers it's measuring the actual spread on your last ten transactions against the mid-market rate at the time each one settled. That number, not a sales pitch, is what should drive the decision. Linka's team can run that analysis with you reach out at linka.xyz.
