The Hidden Margin: What UK Banks Really Charge to Send Money Abroad

Across 10 core global corridors, UK high-street banks extract an average 4.56% on international transfers, compared to 0.45% with transparent digital routes. On a £1,000 transfer, that is £41.10 lost to hidden exchange-rate markups and correspondent deductions that never appear on a fee line.

Add to that mortgage rates that remain stubbornly high and private rents climbing at 8.2 per cent, and it's clear this rare bit of good news isn't shared equally. Whether you actually feel better off this year depends entirely on where your money sits: tucked away in savings, tied up in a mortgage, or handed over each month to a landlord.
