Cross-border payments for automotive suppliers: SWIFT, cards and stablecoins

For automotive suppliers, payment infrastructure is part of the supply chain. A delayed transfer may postpone shipment, create an FX mismatch or leave a distributor waiting for confirmation before goods can be released.

In 2026, international suppliers usually have three main options: bank transfers through SWIFT, card payments and digital-asset settlement, including stablecoins. Each solves a different business problem.

An expert perspective on the latter comes from Matt Higginson, distinguished partner at McKinsey and global leader of its blockchain and digital assets practice. His work focuses on digital payments, stablecoins and tokenized money for banks, fintech companies and financial infrastructure providers.

Three payment methods compared

1. SWIFT: best for established, high-value B2B relationships

Bank transfers remain the standard choice for large invoices between manufacturers, wholesalers and distributors.

Their main advantages are familiarity, established compliance procedures and suitability for high-value transactions. SWIFT has also become much faster: the network reported that around 75% of cross-border payments reached the beneficiary institution within 10 minutes in 2025.

However, the final credit may still depend on correspondent banks, local banking hours, currency conversion and the recipient bank’s internal processes.

Best suited for: large invoices, regular distributors and established counterparties.

2. Cards: best for smaller and urgent orders

Cards are convenient when a buyer wants to complete a payment immediately without arranging an international bank transfer. They can work well for samples, spare parts and relatively small online orders.

The main limitation is cost. Percentage-based processing fees become more noticeable as invoice size grows, while international payments may involve additional cross-border or FX charges. Card transactions can also be disputed through chargebacks.

Best suited for: smaller transactions where speed and convenience matter more than transaction cost.

3. Stablecoins: useful for 24/7 cross-border settlement

Stablecoins add another option to international B2B payments. They can move between wallets outside conventional banking hours and may reduce the number of intermediaries involved in a cross-border transaction.

McKinsey estimates actual stablecoin payment activity at around $390 billion annually, with B2B payments accounting for approximately $226 billion. This remains small compared with the global payments market, but shows that stablecoins are increasingly being used for commercial settlement rather than only crypto trading.

For an automotive supplier, the benefit is not simply “accepting crypto”. The practical value is having another payment rail when buyers and sellers operate in different countries, currencies and banking schedules.

Companies do not necessarily need to build blockchain payment infrastructure themselves. A specialised crypto payment processing platform can handle the technical layer required to accept and process cryptocurrency payments.

If a company accepts volatile digital assets rather than stablecoins, exchange-rate exposure becomes another consideration. In this case, automatic crypto conversion and settlement can be used to convert incoming assets into a more stable settlement asset according to the available payment infrastructure.

Best suited for: international transactions where 24/7 availability and alternative settlement rails are important.

Practical ranking by business scenario

1. Large recurring B2B invoices — SWIFT
The most conventional choice for long-term manufacturer and distributor relationships.

2. Small or urgent purchases — cards
Convenient when the customer needs to pay immediately and transaction size is relatively low.

3. International settlement outside banking hours — stablecoins
Worth considering when counterparties need another cross-border payment route and appropriate compliance processes are in place.

Which method should an automotive supplier choose?

There is no universal winner.

The right payment method depends on six factors:

1. invoice size;
2. countries involved;
3. settlement speed;
4. FX exposure;
5. transaction costs;
6. compliance requirements.

For many international automotive businesses, the most practical strategy is therefore not replacing one payment system with another, but maintaining several payment rails.

SWIFT remains strong for traditional B2B settlement. Cards provide convenience for smaller transactions. Stablecoins can complement both when a company needs 24/7 cross-border settlement and already has the necessary compliance and treasury processes.

The strongest payment infrastructure is ultimately the one that gives buyers several appropriate ways to pay while keeping settlement predictable for the supplier.
