Your funds in pots are held as cash, but now you can opt to switch the funds to “assets”, which currently means the world index - I’m assuming they’re planning to add more options.
Edit: sorry, not thinking straight. You hold balances in each currency. You can select whether to move from Cash to Assets for each currency. I use my euro and dollar balances like pots, so I was getting muddled. You can switch any currency balance to Assets.
So I’ve played with this a bit and decided it’s not for me.
Firstly, the fee is too high.
Then I don’t really understand the advantage to having an investment as a quasi cash balance.
It also seems wise hasn’t thought it through, because switching from Assets to Cash takes “up to 2 working days”, but I just used the debit card to withdraw 97% instantly and have left the 3% remaining to switch to cash. Hmm.
