Maybe the option to buy major currenices off monzo and store them into their own pots. For example Im going on holiday to Italy and I see the euro is weaker than the pound and it will see to nicely when I travel in a few weeks to Italy I can purchase the euro at the monzo price and add it to my euro pot. Similar to forex but on a smaller scale.
I’m not sure that Monzo have any plans to allow you to hold currencies in your account. But it’s s nice idea.
Transferwise Borderless offers this, if you are interested.
I like the idea. And might be nice for set budgeting a holiday
