I just want to point out that the situation of Hong Kongers fleeing the current regime in Hong Kong is quite challenging.
Perhaps your financial institutions could stop thinking about interest rates and the potential money involved, and start thinking about criteria that may be relaxed, for example, for people who have already started the permanent residency process?
Couldn't you allow these people to make an early withdrawal if you have proof that they started their permanent residency process? Would you rather continue to work hand in hand with totalitarian regimes?
