Geoffrey, before Jan 2024 I never had any issues with SEPA transfers to IBKR. Every month I sent money and it arrived within a day all the time.
I’m getting salary to bunq, and for me using wise is unnecessary extra step which I can avoid.
For example, I sent money from Revolut account and Bunq one more time 25 Apr
25 Apr, 10;21 - money sent from Bunq to IBKR
25 Apr, 10:28 - money sent from Revolut to IBKR
25 Apr, 11:44 - money arrived to IBKR from Revolut
25 Apr, 21:01 - money arrived to IBKR from Bunq
As you can see, if everything works fine, money arrives so fast, especially with Revolut.
