_Cross-border B2B payments are transfers between businesses in different countries, usually with a currency conversion along the way. This guide explains why they still cost 2-3.5% and can take days, which fees make up the bill, and how stablecoin rails fit alongside banks. [See how Tempo supports cross-border payments](/solutions/cross-border-payments/)._

SWIFT gpi and the ISO 20022 migration have made international payments faster and easier to track, and many wires now arrive within hours. Costs have moved less. A [Bank of Canada study](https://www.bankofcanada.ca/wp-content/uploads/2026/10/sap2026-49.pdf) of 2021 to 2024 data found bank margins of 2-3.5% on the payments Canadian businesses send abroad, and final settlement can still take days in some corridors.

For a finance team paying suppliers in several countries, those margins and delays show up as higher cost of goods, cash held in transit and extra buffers to cover late arrivals.

## What are cross-border B2B payments?

Cross-border B2B payments are transfers of money between businesses in different countries, such as a U.S. manufacturer paying a supplier in Canada or a parent company funding a subsidiary in Mexico.

Most move as bank wires through the correspondent banking network, though card networks, payment service providers and stablecoin rails also carry them. They differ from consumer remittances in size and frequency: business payments are larger, often tied to invoices, and need data that accounting teams can reconcile. The broader guide to [cross-border payments](/learn/cross-border-payments/) covers the rails in more detail.

## Why cross-border B2B payments take days to settle

Fewer than half of cross-border B2B payments settle within one business day, according to the [Financial Stability Board](https://www.fsb.org/uploads/P091025-1.pdf), and some routes take much longer. The delays come from the banking chain and from the receiving bank.

### The intermediary banking chain

[Correspondent banks](/learn/correspondent-banking-services-for-payouts/) hold accounts with one another so that money sent through one can be paid out at another. When the sending bank has no relationship with the recipient's bank, one or more intermediary banks connect them. Most chains are short, with an [average of one intermediary bank](https://www.bis.org/publications/swift-gpi-data-indicate-drivers-fast-cross-border-payments), and [longer chains](https://www.swift.com/swift-gpi-driving-payments-revolution) don't always add time, though they often add cost.

What travels is the payment instruction, not the money. Each bank settles its leg by adjusting balances on its own books and on its own schedule, which can delay final settlement.

### Compliance holds, cutoff times and FX windows

Once the instruction reaches the destination bank, most remaining delays happen there:

- **Compliance checks.** Sanctions alerts, suspected fraud and incomplete payment data can trigger manual review before the bank credits the payment.
- **Business hours.** A payment that arrives after hours waits for the next business day. One that lands the Friday before a holiday weekend may not be credited until Tuesday.
- **FX windows.** Currency conversion follows set cutoff times and, in some markets, fixed daily rates. Late payments roll over to the following business day.

Many payments on traditional rails finalize within a business day. The ones that take longer usually hit several of these conditions at once.

## The main cost drivers behind cross-border payment fees

The cost of a cross-border payment builds up across each stage of the transfer. With B2B cross-border payments reaching [$34.8 trillion in 2025](https://assets.fxcintel.com/newsletter/FXC%20Intelligence%202026%20Cross-Border%20Payments%20Market%20Sizing%20Report.pdf), small percentages add up to large sums.

### The cross-border fee stack

Several charges can apply to a single payment:

- **Sending bank wire fee.** The originating bank charges the payer for initiating the transfer. The guide to [wire transfer fees](/learn/wire-transfer-fees/) compares typical charges.
- **Intermediary bank fees.** Each correspondent bank in the chain can deduct its own charge.
- **Receiving bank fee.** Beneficiary banks may charge to receive payments. The [FSB reports](https://www.fsb.org/uploads/P091025-1.pdf) this ranges from about 1.3% for payments under $500 to about 0.1% for payments over $20,000.
- **Compliance or investigation fees.** Banks may charge when a payment is flagged for manual review or a discrepancy needs resolving.

### FX markups: the largest hidden cost

When a bank converts currency, it usually builds a margin into the exchange rate it quotes. The margin does not appear as a separate line item, so it is easy to miss, and it is typically the largest single charge. In the Bank of Canada study, the FX spread made up [more than 75%](https://www.bankofcanada.ca/wp-content/uploads/2026/10/sap2026-49.pdf) of what banks charged.

Take a U.S. company paying a Canadian supplier $20,000:

| Item              | Value                           |
| ----------------- | ------------------------------- |
| Amount sent       | $20,000 USD                     |
| Mid-market rate   | 1.40 CAD per USD                |
| Bank FX markup    | 2%                              |
| Rate applied      | 1.40 × 0.98 = 1.372 CAD per USD |
| Supplier receives | $27,440 CAD                     |

At the mid-market rate the supplier would receive $28,000 CAD. The markup leaves it with $27,440 CAD, a difference of $560 CAD, or $400 USD, that never appears on a fee schedule.

### Prefunding and trapped liquidity

Banks and payment providers [prefund](/learn/prefunding/) accounts abroad so they hold enough local currency to pay out on demand. That cash cannot be used elsewhere while it sits in foreign accounts, and providers recover the cost through the fees they charge customers.

## How stablecoins change cross-border B2B settlement

Stablecoin rails add a second settlement system that runs alongside wires and ACH. Value moves together with the payment instruction, so the settlement leg does not pass through a chain of correspondent banks, and it runs on weekends and outside banking hours.

### Fewer intermediaries in the settlement leg

A stablecoin transfer settles directly between the sender's and recipient's wallets on the network. That reduces the need for prefunded accounts in each destination and removes intermediary bank fees from the settlement leg.

Banks and providers still handle the edges. Converting local currency to stablecoins and back depends on [on- and off-ramps](/learn/stablecoin-on-off-ramps/) that follow local banking hours, payouts to a supplier's bank account still use domestic rails, and capital controls, licensing and the legal treatment of stablecoins vary by country.

### Dollar-denominated network fees

On payment-focused networks, network fees are priced in dollars rather than a volatile gas token, which makes the cost of each payment easier to forecast. FX conversion and ramp fees remain separate and depend on the provider and corridor.

## Where Tempo fits

Tempo is a Layer 1 network for stablecoin payments that businesses can add to their existing banking setup for the settlement leg of cross-border B2B payments.

- **Settlement in under a second.** Stablecoin payments settle onchain in under a second with no re-orgs, 24/7, while conversion and bank payouts follow their own timelines.
- **Dedicated payment lanes.** [Reserved blockspace for payments](https://docs.tempo.xyz/protocol/blockspace/payment-lane-specification) keeps payment traffic from competing with unrelated network activity.
- **Fees in stablecoins.** [Network fees](https://docs.tempo.xyz/protocol/fees) are paid in supported USD stablecoins, with sub-cent fees for standard transfers and no separate gas token to hold.
- **Invoice references onchain.** [Transfer memos](/learn/transfer-memos/) carry a 32-byte reference, such as an invoice ID or ISO 20022 data, to help match payments with offchain records.

FX conversion, ramp and payout partners, compliance and the legal review of each corridor remain the customer's responsibility. [Talk to the Tempo team](/contact/) about your cross-border B2B flows.

## FAQ

### What are cross-border B2B payments?

Cross-border B2B payments are transfers between businesses in different countries, such as paying an overseas supplier or settling with a foreign subsidiary. They usually involve currency conversion and move through correspondent banks, card networks or payment providers.

### Why do cross-border B2B payments take days?

Each bank in the correspondent chain settles its leg on its own schedule, and the receiving bank can hold a payment for compliance review, business hours or FX cutoffs. A payment that arrives late on a Friday before a holiday weekend may not be credited until Tuesday.

### What is the biggest cost in a cross-border B2B payment?

The FX markup is usually the largest charge. A Bank of Canada study found it made up more than 75% of what banks charged Canadian businesses on payments sent abroad.

### Are stablecoin rails a replacement for traditional banking?

No. Stablecoin rails run alongside correspondent banking, and businesses still need bank accounts and on- and off-ramp providers to move between stablecoins and local currency.

### Is stablecoin settlement cheaper than a wire transfer for B2B payments?

The onchain settlement leg usually costs less than a wire because it skips intermediary bank fees. The full cost of a stablecoin payment also depends on the on- and off-ramp providers, FX conversion and local payout partners involved.
