CBDCs are pretty much just fully digitized dollars with likely far more restrictions. Not sure about the economic impact being good or bad, but it's surely bad for the privacy of the masses.
There is one big economic impact : banks.
If you own a cdbc, you will have cut off the intermediary, the bank, and you will own something straight from the federal reserve or central bank.
There will be no more need for the banking system to hold fiat .
This is a huge economic impact.
Personally, I don't believe big democracies like Europeans and USA will let per
People own a lot of cbdc, specially due to the banking system lobby (they will be much affected)
And no government want a financial crisis.
Maybe in countries like China and Russia where rights are more restricted and there is a bigger control from the government over the economy it is possible there cbdc will grow faster.
