What Is a CBDC (Central Bank Digital Currency)?

Bottom line: a digital version of national money

A CBDC (Central Bank Digital Currency) is a digital form of fiat money issued by a central bank — the same "national money" as the yen or dollar, usable digitally.

Key points

- Issued by a central bank (the Bank of Japan, for the yen)

- Value fixed to the fiat currency (1 digital yen = 1 yen)

- Unlike Bitcoin, the price does not move

- Different issuer from a private stablecoin

How it differs

IssuerPrice
Crypto (BTC etc.)None (decentralised)Volatile
StablecoinPrivate companyPegged to fiat
CBDCCentral bankThe fiat itself

Japan's situation

The Bank of Japan has run digital-yen experiments. Nothing is decided — it's a careful study phase. Relatedly, Japan is seeing movement on yen-pegged stablecoins.

Don't confuse it with crypto

A CBDC is centrally managed national money; whether it even uses a blockchain is a design choice. Treat it as separate from decentralised crypto.
