For each IBKR account, you designate a single base currency that determines the account's statement and margin requirement translation currency. However, deposits and withdrawals may be made in any non-base currency in AUD, CAD, CNH/CNY, CHF, CZK, DKK, EUR, GBP, HKD, HUF, INR, JPY, MXN, NOK, NZD, SEK, SGD or USD.
US IRA margin accounts are never allowed to borrow currency and must pay in full with the native currency of the asset. This may be accomplished by converting currency before the trade. Integrated Investment Management Account features are not available for multi-currency cash accounts. However, multi-currency cash accounts may trade in multiple currencies by trading currencies through our IDEAL FX* network.
* IDEAL FX includes a suite of FX execution services including IDEAL and IDEAL PRO.
