I don't see how it fixes the problem or how it is even remotely implemented. The local bank my cousin runs dwarfs the network of banks in the bahamas.
Implementing it amid hyperinflation doesn't really solve the problem of a collapse of pricing. Pricing and currency are allocators for production and consumption. A CBDC implemented amid that may have tools intended for control - but I don't really see it playing out that well.
We have a higher risk of a CBDC if they continue to hike. That not only pulls more liquidity out of the market, it causes a deflation of balance sheets against deposits. If I put $1000 in the bank, the bank needs to keep assets on hand to cover that in the event I make a withdrawl. If stocks, assets, and foreign currencies are deflating, that squeezes the bond market as the banks compete for assets.
At that point is when you could inject a form of alternative liquidity, such as a CBDC. Or, more likely, deficit spending as the politicians try to buy votes.
That's the other thing, here… there's a civil war going on between the fed and the government. The fed is tasked with two things - protecting the value of the dollar and managing inflation. While it does give the treasury a blank check to pretend bonds are backed when they aren't - the money printer is congress, ultimately.
If we ever got rid of the fed, congress would have to work from a budget constrained by tax revenues - which is abject heresy in the halls of D.C. The fed is being handed a mess by a bunch of howling monkeys and getting shit thrown at them for their trouble - so there is the possibility the fed will continue hikes if it is looking to go for a CBDC as that actually has a halfway coherent means of being applied. Though I still don't know what the legality of it would be.
