Your cash balance in this currency is most likely not settled yet and that is why the withdrawal will created a margin loan. If you have recently executed a currency conversion or closed a position, the cash withdrawal of the proceeds will increase your margin loan on your margin type account until the trade has settled. This could take up to two (2) business days (T+2).
Please Note
- IBKR Ireland, IBKR Central Europe, and IB UK accounts are not allowed to withdraw funds on margin due to regulatory reasons.
