What is an international business bank account

An international business bank account enables UK businesses to send and receive payments in multiple currencies, hold foreign currency balances, and manage cross-border transactions. Some providers offer dedicated multi-currency accounts with separate IBANs for each supported currency. Others provide a standard sterling account with international payment capability and FX conversion at the point of transaction.

The UK exported approximately £855 billion in goods and services in 2023, according to ONS data. UK businesses engaged in international trade face FX conversion costs on every cross-border transaction. These costs vary significantly between providers: CMA9 banks typically apply a 2 to 3 percent margin above the interbank rate, while Wise charges 0.35 to 0.75 percent on the same transactions.

Wise Business versus HSBC for international payments

The two most common comparisons for UK businesses with international payment needs are Wise Business (lowest FX margins, no FSCS) and HSBC Business (higher FX margins, FSCS protected, global network).

Wise provides local account details in 10 currencies including USD, EUR, AUD, CAD, and SGD. Businesses can receive payments in those currencies without conversion, hold balances, and convert at mid-market rates with fees of 0.35 to 0.75 percent. For a business receiving USD 50,000 per month from US customers, the difference between Wise (0.5 percent) and HSBC (2.5 percent) represents approximately £800 per month in FX savings.

HSBC provides trade finance facilities including letters of credit, documentary collections, and trade loans that Wise does not offer. For businesses needing structured trade finance alongside international payments, HSBC is the stronger choice despite higher FX margins. Wise is not a bank - it is authorised as an electronic money institution. Customer funds are safeguarded but not FSCS protected.

IBAN and SWIFT for UK business accounts

UK bank accounts have IBANs in the format GB followed by check digits, bank code, sort code, and account number. All CMA9 banks provide IBAN details for UK business accounts. Wise Business provides local IBANs in multiple currencies, allowing US customers to pay a US-format account number in USD without triggering international wire fees on the sending side - a significant practical advantage for businesses receiving frequent small payments from overseas customers.

SWIFT international transfers are the standard mechanism for cross-border payments outside the SEPA zone. Most CMA9 banks charge separately for international SWIFT payments, typically £15 to £40 per transfer. Wise includes international transfers within its standard percentage fee structure with no flat fee on most currency pairs.

Multi-currency account versus sterling account with FX

A multi-currency account holds separate balances in each currency, enabling a business to receive USD, convert some to GBP for expenses, and hold the remainder in USD for future USD payments without converting twice. A sterling account with FX capability converts every incoming foreign currency payment to GBP at receipt and converts every outgoing foreign currency payment at sending.

For businesses with matched currency flows - receiving USD from customers and paying USD to suppliers - a multi-currency account avoids unnecessary double conversion. Wise, Revolut Business, and Airwallex offer true multi-currency accounts. CMA9 banks generally provide sterling accounts with international payment capability; separate foreign currency accounts can typically be arranged but are not standard.

Foreign currency balances: tax and accounting considerations

UK limited companies holding foreign currency balances must account for exchange gains and losses under HMRC foreign exchange rules. When the company converts foreign currency to sterling, or when the sterling value of a foreign currency balance changes at year-end, a foreign exchange gain or loss arises. These are taxable or deductible for corporation tax purposes.

Accounting software with multi-currency support - Xero, QuickBooks, and FreeAgent all include this - handles the calculations automatically if the bank feed is connected. Manual tracking of currency transactions without accounting software support significantly increases the complexity of tax preparation.

FSCS protection and international business accounts

HSBC, Barclays, and all other CMA9 banks are FCA-authorised with FSCS protection up to £85,000. Wise, Revolut, and Airwallex are FCA-authorised as e-money institutions - not banks - and are not FSCS protected. Businesses holding significant currency balances with non-bank providers should understand this distinction. A business holding £100,000 in a Wise account has no FSCS coverage on any of that balance. The same amount spread across HSBC and Barclays has full FSCS coverage on each portion.

International payments: regulatory framework in the UK

International payments from UK business accounts are regulated under the Payment Services Regulations 2017, which implement the EU Payment Services Directive 2 (PSD2) in UK law following Brexit adaptation. UK payment service providers must provide clear information on transfer fees, exchange rates, and execution times before a payment is initiated. The FCA supervises compliance for UK-authorised providers.

SWIFT, the international banking messaging network, is the primary infrastructure for cross-border payments outside the SEPA zone. SEPA covers 36 European countries and enables euro transfers with the same speed and cost as domestic UK payments. UK businesses with frequent EU payments can reduce costs substantially by using SEPA transfers rather than SWIFT for euro-denominated payments.

The UK left the SEPA payment zone when it left the EU, meaning UK banks are no longer direct SEPA participants. However, euro payments to the SEPA zone are still processed as cross-border euro transfers by UK banks using correspondent banking arrangements. Wise and Revolut maintain SEPA access through their European entities, which can provide faster and cheaper euro transfers for UK businesses than traditional bank SWIFT routes.

International business account: what businesses need one

Not every business trading internationally requires a specialist multi-currency account. A UK business that invoices overseas customers in sterling and receives sterling payments does not need international banking infrastructure beyond a standard UK account with international payment capability.

A multi-currency account becomes materially beneficial when: the business receives payments in a foreign currency from overseas customers and needs to hold that currency before converting; the business pays overseas suppliers in their local currency; the business employs staff in other countries and pays salaries in local currency; or the business trades across the Northern Ireland and Republic of Ireland border with regular euro-denominated transactions.

For UK businesses with occasional international transactions (fewer than 10 per month at low values), the simplest approach is a standard sterling account at any major bank, using the bank's standard international transfer service despite higher margins. The administrative complexity of a multi-currency account may outweigh the FX savings at low transaction volumes.

Frequently asked questions

International payments and UK regulation

International payments from UK business accounts are governed by the Payment Services Regulations 2017. These regulations require UK payment service providers to supply clear information on transfer fees, exchange rates, and execution times before a payment is initiated. The FCA supervises compliance for all UK-authorised providers.

SEPA - the Single Euro Payments Area - covers 36 countries and enables euro transfers with domestic speed and cost. The UK left the SEPA payment zone on leaving the EU, meaning UK banks are no longer direct SEPA participants. However, Wise and Revolut maintain SEPA access through their European entities, providing faster and cheaper euro transfers for UK businesses compared to traditional bank SWIFT routes. For UK businesses with frequent EU payments, this is a meaningful cost difference: a SEPA credit transfer within the eurozone costs pence, while a SWIFT euro transfer from a UK bank typically costs £15 to £30 plus the FX margin.

Businesses trading internationally should also be aware of HMRC foreign exchange rules. When a UK limited company converts foreign currency to sterling, or when the sterling value of a foreign currency balance changes at the accounting year end, a taxable exchange gain or deductible exchange loss arises. Accounting software with multi-currency support handles these calculations automatically when connected via open banking to the business account.

What is the best business bank account for international payments in the UK?

For low FX margins, Wise Business offers the lowest transaction costs with local account details in 10 currencies. It is not FSCS protected. For FSCS protection and trade finance alongside international payments, HSBC Business provides the strongest combination. The right choice depends on transaction volume, currency mix, and whether trade finance or FSCS protection is the priority.

Do UK business banks charge for international transfers?

Yes. CMA9 banks typically charge a flat fee of £15 to £40 per international SWIFT transfer plus a 2 to 3 percent FX margin above the interbank rate. Wise charges a percentage fee of 0.35 to 0.75 percent with no flat fee on most currency pairs. Revolut Business includes a monthly allowance of fee-free transfers on paid plans.

Can a UK limited company hold a foreign currency account?

Yes. CMA9 banks including HSBC, Barclays, and NatWest offer foreign currency accounts for UK limited companies. Wise Business provides equivalent multi-currency functionality with lower FX margins and faster setup.

Is Wise Business FSCS protected?

No. Wise is authorised by the FCA as an electronic money institution, not a bank. Customer funds are safeguarded in segregated accounts at regulated banks but are not eligible for FSCS protection. In the event of Wise failing, customer funds are subject to recovery under the e-money safeguarding regime rather than the FSCS compensation scheme. The safeguarding regime requires funds to be held in dedicated accounts ring-fenced from the institution's general creditors, but the recovery process is more complex and less certain than the FSCS scheme which provides straightforward compensation up to £85,000 per institution per legal entity. For businesses holding large balances with Wise, this distinction is material. For businesses using Wise primarily for transaction cost reduction on payments that flow through quickly rather than being stored as balances, the practical risk difference is lower.

What IBAN do I give international customers?

UK business accounts have IBANs in the format GB followed by check digits, bank code, sort code, and account number. Your bank provides the full IBAN in online banking account details. Wise Business additionally provides local account details in USD, EUR, AUD, CAD, and other currencies, enabling international customers to pay using local transfer methods without international wire fees.
