A couple threads out there, if you’re in the US, this thread is the most relevant
I did IBKR, and they weren’t exactly thrilled to have me only use them for forex, but they didn’t close my account or anything (and then I ended up using them for other stuff, so go figure)
In my opinion IBKR has a rabid compliance department. They offer forex but I believe they intend it for internal arbitrage and hedging, so if you use it to transfer foreign currency to other accounts you may own they get quite uptight about it. I think they don’t want to deal with the compliance burden imposed by the US government so they will potentially threaten to close your account.
However, as far as I can tell even the Portuguese version of Coinbase, for example, requires you to trade in USD. Maybe there is a European equivalent of Coinbase to convert the EURC stablecoin to euros. I don’t know of it.
I used my cash management account at Fidelity to transfer funds for the investment and found they were very helpful. I have heard Schwab was also helpful. etrade, which I attempted to use, was not so helpful however.
It’s not a loaded question, but are you totally ok transferring more than a couple of $k on Wise? Every time I tried it went into some compliance check status so I quickly abandoned the attempts. Even with official banks with physical offices and named human CEOs it is often difficult to trace and recover your own money. What with fintechs with AI a the helm?
I transfer my funds from Santander Bank in the US in dollars to my Bison Account in Portugal in Euros. Bison Bank exchanges the dollars to euros at a reasonable rate upon receipt of the dollars and Santander charges me 40 dollars per wire transfer. Santander offers to exchange dollars to euros for free (?) before transfer but I find their exchange rate is significantly higher (several points higher than Bison) in the end costing much more.
