Your Wise account should give you ABA/account details for a US dollar sub-account, so you can wire USD from your bank to the US "side" of your Wise account. Should cost next to nothing.

At the time I posted what you're replying to, Wise was not supporting US account details so it was not possible to initate an external ACH into the account (maybe a wire would have been possible). They have since fixed that.

The only disadvantage is that you have to hold a positive balance at Wise on which you earn no interest.

They are paying a bit over 1% on my EUR balance ATM which is better than nothing, if not a lot better. Varies by currency I expect. I would love to find some way to keep cash balances in EUR that were more or less keeping up with inflation but until I have my residency card here in PT I don't think I'm going to be able to create a brokerage account, so ATM I'm keeping cash in the Wise US account where it gets around 4%. Not thrilled with that since at any moment the Orange Blight might decide to block foreign currency transactions or do something stupid that devalues the USD another 15%. Maybe I could do something through IB though.
