Pros and cons
Nu Mexico
Pros
- Everyday account that organises money through savings pots
- Accessible savings paired with optional frozen savings structure
ZA Bank
Pros
- Instant FPS transfers cost nothing, and SWIFT transfers carry no ZA Bank fee.
- A minimum deposit of HKD 0, so a balance can start small and grow.
- Support runs on email, phone and chat, so help is not limited to the app.
Cons
- The headline rate of 0.01% ranks 447 of 473, so this is a place to keep money rather than grow it.
- A variable rate on an easy access account gives no term in which to lock a better rate for longer.
- Digital-only handling under free atm and digital only means no branch or counter service, so cash and paperwork happen in the app.
Who each suits
Nu Mexico
Who it suits
- People who prefer digital management for routine money
- People who like separate pots for everyday goals
ZA Bank
Who it suits
- Travelers and businesses, the audiences ZA Bank lists, who need easy-access money in 11 currencies.
- Holders who want a minimum deposit of HKD 0 rather than a barrier to opening.

Who should look elsewhere
- Readers shopping on listed rates, where Plazo ES shows 24.19% and AXI Card Tarjeta y Credito shows 21.59%.
