governments are already converting from physical currencies to digital currencies

and it makes sense - it's cheaper, more traceable and more controllable. digital currencies are programmable - purely physical are not

i wrote a thread about how virtually central banks are moving to digital currencies - via retail & wholesale CBDCs:

decentralized digital Euro will not work, because the ECB needs to have full control over it

retail CBDCs are direct central bank liabilities on the balance sheet. so "neutral market infrastructure" would not work, because the ECB needs to have full control over it. you can also imagine how many regulations need to be accounted for by the implementation

it most likely won't use a public blockchain for base implementation, and it's definitely not like stablecoins ๐Ÿ˜„

digital euro also needs to support offline payments, which isn't currently widely supported in DeFi. Zero Knowledge Proofs enable some potential solutions for this, but I don't believe that that's with what the ECB is going with now

real world and financial asset tokenization is ongoing worldwide, with transactions mostly settled in CBDCs

government and corporate bonds are the most common RWA to be tokenized

>80% of central banks plan to operate the DLT/blockchain for wholesale CBDCs themselves, hinting an in-house blockchain solution, and not a public and permissionless ledger

User

however, even if CBDCs are implemented using blockchain - it's unlikely to be a public, permissionless blockchain like Ethereum

>50% of central banks in both, advanced and emerging economies are considering using DLT for wholesale CBDCs

this means that wholesale CBDC is likely to be implemented using some form of blockchain technology - much more likely than the retail CBDC

only 6% of advanced economies (AE) central banks and 40% of emerging economies (EM) central banks are considering distributed ledger technology (DLT) as an implementation layer for retail CBDCs

here, consider DLT = blockchain

91% of central banks are working on CBDCs, but not on a public blockchain

85 out of 93 central banks (โ‰ˆ94% of global economic output) are engaged in some form of CBDC work

however, don't expect CBDCs to be implemented on permissionless blockchains like Ethereum

thus, wholesale CBDC is a tokenized/digital version of central bank reserves used by the financial market infrastructure (FMI) and banks

it also lives on the liability side of the central bank

User

wholesale CBDC will be used by financial institutions only, such as commercial and central banks for interbank and market settlement

wholesale CBDC will only be transacted between select financial institutions - it's not something you'd use as a regular business or consumer

retail CBDC will be used for day-to-day payments, similar to the ones you do with with a credit card. this is the type of CBDC you can use for business and consumer transactions, such as paying for a supermarket purchase

wholesale CBDC vs retail CBDC - what's the difference?

there's two types of central bank digital currencies (CBDC): retail CBDC and wholesale CBDC

โž– retail CBDC = used for ordinary transactions. digital version of the cash

โž– wholesale CBDC = used for interbank/financial institution settlement. tokenized central bank reserves

retail CBDC is central bank money, so converting bank deposits into digital Euro changes the composition of the monetary base - fewer commercial bank reserves at the central bank, more central bank CBDC liabilities

retail CBDC conversions settle in reserves

ECB plans to limit the amount of digital Euro CBDC a wallet can hold

this means you will be limited the amount of digital EUR you can own

this applies only to retail European Central Bank CBDC, not wholesale. the idea is to prevent excessive outflows of deposits from banks
