How could a central bank digital currency affect financial privacy?

A central bank digital currency could make it easier for people to see what others are doing with their money, like looking through a window at a toy store.

Imagine you have a piggy bank where your allowance goes, that's like traditional money. Now, imagine the bank gives you a special kind of smart card, this is like a central bank digital currency, or CBDC. It lets you spend your money easily, just like using a credit card at the toy store.

If the piggy bank is private, only you know how much money you have and what you buy. But with a smart card, sometimes the bank can see what you're buying, it's like having a window in your piggy bank that lets others peek inside. This means the bank or maybe even other people might know when you buy candy instead of toys.

Sometimes this is okay, it helps keep things fair and safe. But if too many windows are open, it can feel like everyone knows what you're doing with your money. That’s why having some financial privacy is important, it's like having a curtain that you can pull down when you want to keep your toy choices a secret!
