Specialist currency brokers typically offer better exchange rates than banks for large international transfers. On a £200,000 transfer, the difference between a bank margin of 1.5% and a broker margin of 0.3% is roughly £2,400 — money that stays in your pocket. See our full guide on why banks give worse exchange rates and use our exchange rate comparison tool to check the difference for your transfer amount.
Bank vs Currency Broker Rates for Large Transfers
Banks apply a fixed margin to the mid-market rate — typically 1–3% — that doesn’t shrink much for larger amounts. Specialist brokers operate differently: margins are negotiable, scale with transfer size, and often sit between 0.2% and 0.5% for high-value transactions.
| Provider type | Typical margin | On £200,000 (GBP/EUR at 1.18) | vs bank |
|---|---|---|---|
| High street bank | 1.0–2.0% | €231,500 | — |
| Online platform | 0.4–0.7% | €233,800 | +€2,300 |
| Specialist broker | 0.2–0.5% | €234,400 | +€2,900 |

What Is the Cheapest Way to Transfer Large Amounts Internationally?
The exchange rate margin is where the real cost sits — not the transfer fee. A £10 wire fee is irrelevant when the margin on a six-figure transfer costs hundreds or thousands of pounds. See our guide on what international transfers actually cost and our full guide to the best way to transfer large amounts internationally.
- Use a specialist broker that prices based on transfer size, not a flat margin
- Avoid converting at your bank without comparing against the mid-market rate
- Time the transfer — a 0.5% move on £200,000 is £1,000
- Ask for the margin explicitly, not just the rate
How to Protect a Large Transfer from Market Moves
GBP/EUR has swung by more than 5% in a single quarter multiple times in recent years. On a £300,000 property purchase, that’s a £15,000 difference. Three tools that reduce exposure:
- Forward contracts — lock today’s rate for up to 12 months. Useful when you know you’ll need to pay but the completion date is weeks away. See our full forward contracts guide.
- Target rate (limit) orders — set your target rate and the transfer executes automatically when it’s reached. No need to watch charts.
- Staged transfers — split a large amount into two or three tranches over weeks. This averages out short-term volatility. Set a rate alert between tranches.
What This Means for You
Buying property abroad
Lock the rate as soon as contracts are exchanged using a forward contract. This is the period where buyers most commonly lose money to currency moves. See our property buyers hub and buying property abroad guide.
Relocating or retiring overseas
Transfer savings in stages rather than all at once. See our expat money transfers guide for how to structure ongoing transfers.
Running a business with overseas costs
Fix rates against known invoices using forward contracts. See our guide on best way to pay overseas suppliers and currency hedging for UK SMEs.
Receiving funds from abroad
If you’re selling property overseas or receiving an inheritance, the same principles apply in reverse. See our guide on selling property abroad and bringing money to the UK.
