Most money today is already digital. Paychecks arrive by direct deposit, and purchases are made by card or phone. Yet that money is created by commercial banks, not by the government. A central bank digital currency, or CBDC, would be something new: digital money issued directly by a country’s central bank, the electronic equivalent of cash.

How a CBDC Differs

The balance in a bank account is a promise from that bank. It is safe because of regulation and deposit insurance, but it is still a private company’s liability. Physical cash is different. A banknote is a direct claim on the central bank. A CBDC would carry that same status in digital form. It also differs from cryptocurrencies. Bitcoin has no issuer and a price that swings widely. Stablecoins are issued by private companies. A CBDC would be official legal tender with a fixed value, backed by the state.

Why Central Banks Are Interested

Supporters see several benefits. Payments could become faster and cheaper, especially across borders, where transfers are still slow and expensive. People without bank accounts could gain access to digital payments through a simple phone wallet. Central banks are also responding to competition. As cash use declines and private digital currencies grow, they worry about losing influence over the money that people actually use. A public option would keep central bank money relevant.

The Concerns

Privacy is the most common objection. Cash is anonymous, while a digital currency run by the state could, depending on its design, allow the government to see or even restrict how people spend. Designers have proposed safeguards, but public trust is hard to win. Banks have their own worry. If households moved large amounts of savings out of bank deposits and into central bank money, banks would have less to lend, and in a crisis the shift could happen very fast. Many proposals include limits on how much a person may hold. Cybersecurity is a further risk for a system an entire country would depend on.

Where Things Stand

A few countries have launched CBDCs. The Bahamas introduced the Sand Dollar in 2020, and Nigeria followed with the eNaira in 2021, though public adoption in both has been limited. China has run the largest experiment with its digital yuan, and the European Central Bank has been developing a digital euro. The United States has moved in the opposite direction. A January 2025 executive order barred federal agencies from establishing or promoting a CBDC, with policy favoring privately issued dollar stablecoins instead.

Conclusion

Central bank digital currencies raise a basic question about who should issue money in a digital age: the state, private banks, or technology companies.
