Multi-Currency Accounts: Advanced Features and Choosing the Right Provider

A multi-currency account is no longer a specialist product reserved for corporate treasury departments. The explosion of fintech alternatives — Wise, Revolut, Airwallex, and others — has put genuinely capable multi-currency banking within reach of any internationally mobile individual or business. But the quality of features varies enormously between providers, and for HNW clients managing substantial flows across currencies, the differences matter.

This guide goes beyond the basics and examines the features that distinguish excellent multi-currency banking from merely adequate: local IBAN availability, exchange rate mechanics, business payment capabilities, regulatory protection, and the trade-off between digital-only and traditional bank multi-currency accounts.

The Core Features That Matter

Number of Currencies Held

The headline number often cited in marketing — Wise holds 40+ currencies, Revolut holds 36 — is less important than which currencies are available and whether they can be held as real balances versus merely converted on demand.

Holding a real balance means your funds sit in the specified currency, on a dedicated account, earning no conversion until you choose to convert. This is essential for:

• Receiving payments in a foreign currency and holding them (e.g., rental income from a Cyprus property in euros)
• Paying in a foreign currency without triggering a conversion (e.g., paying a UAE contractor in AED)
• Holding currencies as a deliberate asset allocation decision

Some providers offer "conversion on spend" rather than true balance-holding — they convert from your base currency at the point of transaction. This is simpler to operate but removes the ability to manage currency timing.

Local IBANs Per Currency

A local IBAN — an account number in the local format for the relevant country — is essential for receiving payments that would otherwise incur SWIFT correspondent bank fees.

Wise: provides GBP (sort code/account number), EUR (IBAN), USD (routing number/account number), AUD, NZD, CAD, HUF, RON, TRY, and several others. The EUR IBAN is particularly valuable — EU SEPA transfers to a local IBAN are free or near-free.

Revolut: provides local GBP and EUR IBANs for UK and EEA residents. Some additional currency IBANs depending on the account tier. US virtual account numbers available for USD receiving.

Airwallex: specifically designed for business; provides local receiving accounts in the UK (GBP), EU (EUR), US (USD), Canada (CAD), Australia (AUD), Hong Kong (HKD), Singapore (SGD), and a growing list. Strong choice for businesses with multiple international payment corridors.

Citibank International Personal Banking: provides accounts in multiple currency accounts within the Citi relationship, accessible via Citi's global ATM/branch network. Fewer currencies than fintechs but full banking infrastructure.

HSBC Premier: global view account aggregation; currency accounts in GBP, USD, EUR, AUD, CAD, HKD, and others depending on jurisdiction. Significantly fewer currencies than Wise/Revolut but with full banking relationship support.

Exchange Rate: Interbank vs Bank Margin

The exchange rate applied when you convert between currencies is where providers most significantly differ:

Interbank (mid-market) rate: the rate at which banks trade currencies with each other. This is the rate quoted on Google/XE.com. No provider passes this rate without any margin — the question is how much margin is applied.

Wise: charges a small, transparent percentage fee (typically 0.4-2% depending on currency pair) and applies the mid-market rate as the base. The total cost is visible before you confirm.

Revolut Standard: applies mid-market rate in standard working hours; a small weekend surcharge applies (1-1.5%) because interbank markets are closed and Revolut carries the overnight currency risk.

High-street banks: typically apply a rate that includes a built-in margin of 2.5-4% above the interbank rate. For a client converting £100,000, this is a cost of £2,500-£4,000 versus a fee-based specialist of around £400-£2,000 depending on the currency pair.

Private bank forex: private banks may offer better rates than high-street retail banking for large conversions but are typically not as competitive as specialist currency brokers for the same amount. For conversions above £250,000, using a specialist currency broker (Caxton, Moneycorp, OFX) alongside a multi-currency account is often cheaper.

Daily and Monthly Limits

Free-tier multi-currency accounts carry conversion and withdrawal limits that may be inadequate for HNW use:

• Wise: no fixed conversion limit; very large transactions may be reviewed. ATM withdrawal limits apply (typically £200-£400/month free, then fees)
• Revolut Standard: currency exchange limit of £1,000/month at the interbank rate (free); above this, 0.5% fee. Premium and Metal tiers have no cap.
• Revolut Metal (£13.99/month): unlimited currency exchange at interbank rate, higher ATM limits

For HNW clients making large periodic conversions (annual property purchase, quarterly portfolio rebalancing), limits are less relevant since individual large transactions should go through a private bank or specialist broker regardless. Limits matter primarily for day-to-day transactional use.

Business Multi-Currency: Payroll, Mass Payments, API Integration

For business owners running internationally — paying staff in multiple countries, collecting customer payments in local currencies, reconciling multi-currency accounts — business-specific features become critical:

Airwallex: built for businesses with international payment needs. Mass payment capabilities (upload CSV for batch payments); API integration with accounting software; multiple currency payroll; virtual card issuance. Strong in the SME-to-mid-market segment.

Wise Business: competitive rates, international payroll and supplier payments, accounting software integration (Xero, QuickBooks). Better suited to SMEs than Airwallex for simpler payment needs.

Revolut Business: covers the basics — multi-currency accounts, international payments, expense management. Less sophisticated than Airwallex for complex business needs but strong UI.

Ebury: institutional-grade multi-currency for businesses with complex FX hedging needs alongside day-to-day transactions. FCA-regulated; offers forward contracts, options.

Regulatory Protection: The Critical Difference

This is the most important distinction that marketing materials often obscure.

FSCS deposit protection (UK): applies to deposits held with FCA-authorised banks and building societies. Covers up to £120,000 per institution per depositor (raised from £85,000 on 1 December 2025). If the bank fails, the FSCS pays out.

E-money safeguarding: applies to electronic money institutions (EMIs) like Wise, Revolut (UK), Starling (note: Starling is a licensed bank, so FSCS applies), and Monzo (FSCS-covered bank). EMIs must hold client funds in a segregated account with a recognised credit institution and must hold specific assets as a safeguard. If the EMI fails, the safeguarded funds should be returned to customers — but this is not the same as the FSCS guarantee. Recovery depends on the quality of the safeguarding arrangements, how the insolvency proceeds, and whether the safeguarded assets are intact.

In practice, well-capitalised and well-run EMIs have good safeguarding — the risk is not zero but it is materially lower than if funds were entirely unsegregated. For large balances, understanding this distinction matters.

Revolut's banking licence: Revolut obtained a UK banking licence in July 2024, meaning UK customer deposits with Revolut Bank UK are now FSCS-protected up to £120,000. However, Revolut operates multiple legal entities across different jurisdictions — ensure the account is with Revolut Bank UK if FSCS protection matters.

Wise's EMI status: Wise is an FCA-authorised EMI, not a bank. Safeguarding applies. For balances above the FSCS deposit limit, diversification across Wise and an FSCS-covered bank is prudent.

Physical Banking: When You Still Need a Branch

Multi-currency fintechs offer excellent digital experiences but have no physical presence. For some banking needs, a traditional bank relationship remains necessary:

• Notarised or certified bank references for property purchases abroad
• Cash deposits and withdrawals above ATM limits
• Complex credit facilities (mortgages, Lombard loans)
• Wire transfers to high-risk jurisdictions that require relationship manager approval
• Trade finance instruments (letters of credit, banker's acceptances)

For internationally mobile HNW clients, the optimal setup typically combines: a primary private banking relationship (HSBC International, Citi International, or equivalent) for significant balances and credit; a Wise account for efficient low-cost international transfers; and a Revolut Premium or Metal account for day-to-day multi-currency spending.
