The bank will be stronger than before if it wants to launch a new crypto under the auspices of the local government, centrally it often becomes the pros and cons in the crypto world where each has an advantage that considers and hopes that crypto is always decentralized on the other hand banks always oppose all reasons with security, it is a scheme that has been read because they want global control even though it is complicated to follow lust only with power.
Not just the banks, but the country in which the blockchain technology is adopted. Nonetheless, it would not really change much if we are referring to decentralization as the centralized aspect is something we most definitely will not stop seeing for now.
However, we have to understand that in cases like this, even with the centralization, there is always a huge transparency which I believe will curb a whole lot of things and most especially when it comes to corruption, but the thing is even at points like this, it totally still depends on the government anyway but one thing I know for sure is that government will never accept decentralization as they always love the control.
