Banks in Singapore have a feature where customers can lock part of their current/checking account balance so it can’t be transferred out digitally.

To unlock it, the customer has to either wait through a cooldown period or go through extra verification. The main use case is fraud/scam protection.

Would this kind of feature actually improve deposit stickiness for the bank? ---- My Thinking is that if a customer voluntarily locks part of their balance, they may be less likely to move that money quickly to another bank or spend it. But I’m not sure if banks would treat this as meaningful from a funding or retention perspective. Would this have any real impact on deposit behavior?
