When a company in Latin America makes an international payment, a supplier payment to Asia, an inter-company settlement in Europe, or a trade finance operation with U.S. partners, it rarely pays only the visible fee. There is a parallel cost, silent and almost universally overlooked: the bank spread on the exchange rate.

The spread is the difference between the real market exchange rate (known as the mid-market rate or interbank rate) and the rate the bank actually offers its corporate client. That gap does not appear on any invoice. It is not labeled "commission." And yet it is entirely real, and in many cases, the single largest cost in the entire transaction.

In practice, banks acquire currencies at the interbank rate and sell them to clients at a marked-up rate that, according to industry data, ranges from 2% to 5% at major global banks, and can reach up to 10% of total transaction value on certain cross-border payment corridors in Latin America. For a company moving hundreds of thousands of dollars monthly in international payments, that percentage translates to tens of thousands of dollars lost annually, none of which ever appeared in a budget line.

The Structural Problem: LATAM Pays More Than the Rest of the World

Latin America is not just any region on the international payments map. It is one of the most expensive.

The reasons are structural: chronic currency volatility in markets like Argentina, Brazil, and Colombia; highly fragmented regulatory frameworks that differ dramatically from country to country; deep reliance on the correspondent banking system with its chain of intermediaries; and a legacy financial infrastructure not built for speed or transparency.

The result is an ecosystem where spreads on LATAM corridors are significantly wider than in developed markets. While in Europe or North America a specialized platform can approach the true interbank rate with margins of 0.5% to 2%, on routes like USD/BRL, USD/MXN, or USD/COP hidden costs accumulate layer by layer.

According to cross-border payment industry analysis, sending $10 million per month via traditional banking rails can leave around $333,000 in transit as floating capital, on top of the FX spread and wire fees of $25 to $50 per transaction. The cost of that idle capital, calculated at 5% annually, amounts to $75,000 to $125,000 per year that simply evaporates.

The Layers of Hidden Cost: What Your CFO Should Know

The bank spread is only the first layer. In B2B international payments across LATAM, hidden costs organize into at least four levels.

1. The FX markup The bank acquires currencies at the real interbank rate and sells them to the client at a margin that is rarely disclosed explicitly. On a $1,000,000 transaction with a 3% spread, that is $30,000 that disappears without appearing on any visible document.
2. Wire and international transfer fees Every SWIFT or international wire transfer carries a flat fee ranging from $25 to $50 per operation. For companies processing hundreds of monthly payments, the cumulative volume is material.
3. Correspondent banking fees Within the SWIFT system, an international transfer may pass through two, three, or even four correspondent banks before reaching its destination. Each one charges a fee, and in many cases those fees are unknown in advance.
4. Float cost or capital in transit Traditional bank settlement takes between one and five business days. During that period, capital is immobilized. For high-volume operations, the cost of that money in the air is a real financial liability.

Why this problem hits harder in LATAM than in other regions

Three factors make the impact of bank spread disproportionately severe in Latin America.

Currencies like the Argentine peso, Peruvian sol, Colombian peso, and Brazilian real experience movements that naturally widen spreads. Banks compensate for that risk with higher margins, which are ultimately absorbed by corporate clients.

Unlike markets with modern instant payment infrastructure, international payments in LATAM still depend heavily on the SWIFT system with all its intermediaries and associated costs.

In most countries across the region, no regulation requires banks to explicitly disclose the margin they apply over the exchange rate.

The alternative that the region's most sophisticated companies are adopting

Over the past three years, a growing number of B2B companies in LATAM have begun migrating their international payments to infrastructure outside the traditional banking system. The driver of this shift is stablecoins, digital assets pegged to the value of the dollar or other currencies, which allow value to be transferred instantly, transparently, and at minimal transaction cost.

For companies that make international payments regularly,  importers, exporters, businesses with regional operations, corporate treasury managing multiple entities, the combination of stablecoins with specialized OTC platforms represents a complete reconfiguration of the cost model: no hidden spread, no immobilized capital, no opacity in exchange rates.

How Linka solves this problem

Linka is the platform built for B2B companies in Latin America that need to move international capital without paying the hidden costs of the traditional banking system.

It operates on stablecoin rails to offer real-time settlement with transparent exchange rates close to the mid-market rate, eliminating the spread that banks apply without disclosing it. A company in Colombia paying a supplier in Mexico, or a treasury settling between entities in Peru and Brazil, can execute it with Linka in minutes with full visibility over the real cost of every operation.

No intermediaries. No immobilized capital. No surprises in the exchange rate.

Bank Spread is an undeclared tax on international trade

For B2B companies operating in Latin America, bank spread is not a technical footnote. It is a structural cost with direct impact on profitability, competitiveness, and the ability to scale international operations.

The good news is that, for the first time in the history of the regional financial system, real, tested, and regulated alternatives exist that allow companies to make international payments with full exchange rate transparency, real-time settlement, and costs that are a fraction of what the traditional banking system charges. Linka is one of those alternatives, built for LATAM and operating across the entire region.

The question is no longer whether it is possible to eliminate the hidden spread. The question is how much longer your company can afford not to.
