My legacy bank accounts have various limits from £200-£500+ (with no obvious reason for them or way to find out what they are). There doesn’t seem to be any practical reason for restricting access to your own money or preventing you from lowering it if you prefer?
What’s Monzo’s limit and how can you see it? How can you change it?
I currently carry about 5 debit cards because sometimes I find myself on a Sunday evening needing cash and that’s the only way to get sufficient from an ATM.
(aside: why the hell don’t UK ATMs let you choose denominations in 2019?)
