It is because the basis of the reserve of CBDC is still the country's financial reserve. CBDC is just a digital version of cash.  The whole financial system and structure of the country are the same so of course, it will not change anything. Even Bitcoin and other cryptocurrencies cannot save anyone's fiat currency.  Because in order to save any fiat currency, the country needs to improve and develop having a positive gain on its GDP to strengthen its financial reserve.



I agree, the economic status of a country is the main reason of a certain fiat currency getting stronger or weaker.

just going by UK paper fiat currency.. of government money creation(bonds and QE)

when UK government want to create say $50b
they create a bond(agreement/loan) with bank of england(central).

this is where they will give the BoE 5.1b a year for 10 years(paid via tax revenue)

this digital $50b is created by BoE and sent to the government treasury account.. to be spent by government for public services. which ends up in circulation and bank(commercial) accounts of employees of public services and thus moves around to wherever they spend it next

this $50b generates $5b(10%) in tax revenue + more on the re-spends as it circulates within a year.

so now the banks(commercial) of the public now has combined extra $50b spread over customer accounts

this also means the government needs to print $2.5billion of bank notes at a print price of $25m(10p per $10 bank note)..
just so that banks(commercial) can have on hand 5% of account balance of the new amounts thats are $50b higher.. (so that ATM's are full to meet the 5% cashflow demands of withdrawals)

but the commercial banks have to buy those bank notes from the government at face value of combined $2.5b (not the governments print price)

so while the banks(commercial) hold $50b of new money. it cost them $2.5b  to end the story of the money creation process

by going CBDC the commercial banks can save themselves $2.5b every time a central bank or government wants to inject another $50b

however it means that the government treasury cannot collect on the $2.475b profit from the money creation. but still has to pay back the $5.1b a year to the BoE in repayments.

however..
by going CBDC the government can ,amdate that commercial banks monitor the income and outgoing of tier 2-3 wallets that are KYC and tax banded. and ensure the commercial banks report incomes over X so that the government can request tax from those accounts easier (send payment requests/invoices or go to court to get court order to mandate payment seizure) which is something not so easy to do in the old fiat way. thus the rich end up actually paying tax and not hiding it away as easily

.. well thats the theory and their best case scenario for CDBC

I agree with you that CBDC cannot rescue fiat because they are really one, CBDC is just digital version of Fiat and its strength depends on the economy of that country. But not all CBDCs will fail, like fiat. If the US launches its own CBDC then surely the US CDBS will have the same strength as their USD.

It's certain CBDCs aren't a solution for any countries' economies, because they are a digital copy of fiat currencies. If fiat didn't solve anything, why its digital format would? Crypto adopters are investing in bitcoin and its pairs mainly due to their profitability, but also because they don't trust what their governments promote and manage in financial terms. Since CBDCs are issued by governments, people will tend to see it in a negative way, just like they see their currently fiat national currencies.

CBDC will help achieve good results for the government because it will be able to track users' transfers and the size of their savings, which is not the required efficiency at present, since a large proportion of the liquidity is used in the black market. But we should not imagine that it may succeed in helping weak currencies on any level.
Another important point that CBDC may succeed in achieving is that stablecoins are forced to be abandoned on trading platforms and the use of CBDC instead. This will definitely help avoid market disasters like the one that happened with Luna Network and Ftx platform.

Just because CBDC and fiat are the same, doesn't mean it can't save fiat. In my opinion, CBDC was made to prevent people to convert their money into world of cryptocurrency as they heard that cryptocurrency is a game changer, many people got rich because of this, and a hassle free mode of payment. They might scared that these will happen because it will really affect fiat worth. In other words, CBDC is just a non volatile cryptocurrency with KYC verified users. So for me, it is made to save fiat as per my knowledge.

I am not a fan of the CBDC system. 

However, I must agree with the statement that the state can build an efficient financial system based on the CBDC system.

All large and medium-sized corporations use such a tool for managing the production and sale of goods (works, services) as budgeting.  The USSR and communist China also used a tool called a planned economy (based on five-year plans) to manage their countries.

CBDC, combined with mandatory product labeling, can form the basis of an incredibly accurate and efficient system for controlling production, sales and consumption.  It will be a system with positive and negative feedbacks, operating in a real-time system.

It is possible that such a system will function autonomouslyunder the control of artificial intelligence/.
