High Street Banks vs Specialist FX Brokers: Which Is Right for Your Business?

The Hidden Cost of Using Your Bank for FX#

High street banks — Barclays, HSBC, NatWest, Lloyds — provide FX services to every business customer, but it is not their primary revenue focus. The result is exchange rate spreads that are typically 2-4% above the interbank mid-market rate for smaller transactions, plus explicit transfer fees of £10-30 per payment. On a £50,000 payment, a 3% spread costs £1,500 in margin versus the mid-market rate. Banks are convenient, the funds move quickly between your accounts, and there is no additional relationship to manage. But convenience has a measurable price, and for businesses making multiple foreign currency payments per month, the cumulative cost is significant.

What Specialist FX Brokers Offer#

Specialist FX brokers — including Convera (formerly Western Union Business Solutions), Moneycorp, OFX, and Wise Business — access the interbank FX market at tighter spreads than retail banks and pass much of that saving to business customers. Typical exchange rate margins from specialist brokers range from 0.3-1.5% depending on transaction size, currency pair, and how often you transact. For a £50,000 payment, the saving versus a bank can be £750-£1,250 per transaction. Specialist brokers also offer forward contracts, market orders, rate alerts, and dedicated account managers — services that most high street banks do not make easily accessible to SMEs.

Provider Comparison: Rates, Fees, and Services#

Wise Business is best known for near-mid-market rates on spot transactions with a transparent fee structure — typically 0.3-0.6% for major currency pairs. It is excellent for frequent smaller payments (£500-£50,000) but has limited forward contract functionality. OFX offers competitive rates on transfers from around £1,000, dedicated account managers for larger clients, and good coverage of emerging market currencies. Moneycorp provides strong forward contract services and is well-suited for businesses hedging regular export receipts or import payables. Convera (formerly Western Union Business Solutions) operates at enterprise scale with comprehensive hedging products. For very large transactions (£500,000+), a direct relationship with a bank FX desk can offer competitive rates, but below that threshold specialist brokers are almost always better value.

When Your Bank Still Wins#

There are genuine scenarios where using your bank for FX makes sense. If you are making very occasional foreign payments (fewer than 6 per year) at small amounts (under £5,000), the administrative overhead of maintaining a specialist broker relationship may not be worth the saving. For time-critical same-day payments where funds need to move between your own accounts instantly, your bank's internal FX may be faster. Some businesses also prefer consolidating all financial relationships with one institution for simplicity. These are valid reasons — just be honest that you are paying a premium for them rather than assuming your bank is competitive.

How to Choose Based on Your Transaction Profile#

The right answer depends on your transaction volume, average deal size, and what tools you need. For businesses making 1-5 foreign currency payments per month under £20,000 each: Wise Business or OFX typically offer the best combination of competitive rates and low friction. For businesses with £50,000-£500,000 monthly FX volume: Moneycorp or OFX, with a forward contract capability, is usually the right fit. For businesses with over £500,000 monthly volume or complex multi-currency treasury requirements: Convera or a direct bank FX relationship warrants investigation. AskBiz tracks your FX transaction history and flags when your total monthly volume would qualify for better rates from a specialist provider.
