Save on international money transfers

When you send or receive an international transfer with your bank, you might lose money on a bad exchange rate and pay hidden fees as a result.
This is because banks hide a fee in the exchange rate, which means that you will spend more on international money transfers than you should.
We recommend using Wise (formerly TransferWise) which is often cheaper. For example, a 500 USD to EUR transfer could be up to 70% cheaper with Wise versus select providers*.
