Expiration dates on CBDCs are proposed as a mechanism to artificially encourage consumption and spending during recessions or depressions, counteracting people's tendency to save due to economic uncertainty.
"the way to get us out of one is to encourage people to go out borrow money and spend that money but whenever there's a recession people are not spending money they're saving money they're scared of losing jobs they are not spending money and so how do you get people to grow the economy if no one wants to spend you put an expiration date on it because that's what will artificially encourage people to go out consume and spend their money or else they'll lose their savings"
