What a central bank digital currency would actually change

The Bank of England and HM Treasury published a consultation on a digital pound in February 2023. Buried in it was a proposed individual holding limit of somewhere between $10,000 and $20,000. Not a slogan, not a leak. A design parameter, printed, with reasoning attached.

That number tells you more about what a retail CBDC is meant to be than almost anything said about it since. It's a cap, and it exists because if people could shift unlimited balances from commercial bank deposits into a central bank liability, banks would lose the funding they lend against. The cap is an admission of the risk.

Start there, because most CBDC arguments are conducted without reference to what anyone has actually proposed.

Two completely different things share one acronym

Wholesale CBDC is a settlement asset for banks and financial institutions. Central banks already give commercial banks reserve accounts, so this is largely a plumbing upgrade. Tokenized reserves, faster settlement, cross-border experiments like the BIS work on multi-currency platforms. Almost nobody outside the payments industry has a view on this, and almost nobody should.

Retail CBDC is the one people argue about. A digital form of central bank money that ordinary people hold and spend. That's the Sand Dollar in the Bahamas, live since October 2020. That's Nigeria's eNaira, launched October 2021. That's the digital euro, which moved into a preparation phase in November 2023 and still awaits EU legislation.

When someone tells you China "launched a CBDC," they mean the e-CNY, which has been in expanding pilots across dozens of cities for years and has never been declared a full national rollout. When someone tells you the Fed is building one, check the date. The Fed's January 2022 discussion paper explicitly said it wouldn't proceed without clear support from both the executive branch and Congress.

Get the category right before you form an opinion. Half the disputes evaporate.

What the design documents actually say

Across the Bank of England, the ECB and most published work, the same architecture keeps appearing.

Intermediated, not direct. The central bank issues the money and runs the core ledger. Private firms handle the wallets, the apps, the onboarding, the customer checks. You wouldn't have an account at the Federal Reserve or the ECB. Your bank or a licensed payment provider would sit in front of it.

No interest paid. Both the digital euro and digital pound proposals treat the thing as a payment instrument, not a savings vehicle. Non-remunerated, deliberately, so it doesn't compete with deposits.

Holding limits. The $10,000 to $20,000 figure in the UK consultation. The ECB has discussed a limit too, without settling publicly on a number. Same logic in both cases.

Offline functionality. The ECB has said an offline mode would settle directly between devices with privacy comparable to cash for those payments. This is the part most often skipped in coverage, and it's the part that matters most to anyone worried about surveillance.

Legal tender status and merchant acceptance rules. The European Commission's 2023 legislative proposal paired the digital euro with a separate proposal protecting the legal tender status of cash. Those two documents came out together, on purpose.

The genuinely disputed parts

Three things are actually contested. The rest is noise.

Privacy. Central banks say they won't see personal transaction data, because the intermediated model puts private firms between them and you. The ECB has been specific about this. Critics respond that "the central bank can't see it" isn't the same as "nobody can see it," and that a system with a central ledger creates a capability that doesn't currently exist, regardless of who's promised not to use it. Both statements can be true simultaneously. A capability built under one legal framework outlives that framework.

Programmability. Designers of the digital pound and digital euro have said the central bank wouldn't restrict what you can buy. What they describe is programmability at the wallet layer, like standing orders or conditional business payments, chosen by the user or a private provider.

The counterweight is a comment that keeps getting quoted, and it's real. Agustín Carstens of the Bank for International Settlements, speaking on an IMF panel in October 2020, contrasted cash with a CBDC by saying the central bank would have "absolute control" over the rules governing its use, and the technology to enforce them. He was describing capability, not policy intent. People on both sides have read into it what they wanted.

Disintermediation. If enough money moves out of commercial banks, lending contracts. Holding caps address this in normal conditions. Whether caps hold up during a panic, when everyone wants the safest instrument at once, is an open question that supporters and skeptics both acknowledge.

The adoption problem nobody predicted

Nigeria is the useful case. The eNaira launched with real institutional backing and went nowhere. Usage stayed low enough that the central bank resorted to incentives and discounts to get people transacting. Even during the cash shortage of early 2023, when there was a direct practical reason to use it, it didn't take off.

The Bahamas has had the same difficulty. Existing payment rails work. Cards work. Mobile money works. Instant payment systems like Brazil's Pix and India's UPI solved the actual consumer problem without any new form of money.

That's the strongest practical argument against retail CBDC and it has nothing to do with surveillance. It's that the problem was already being solved by faster rails on top of existing bank money.

Where it stands, as of now

In the United States, an executive order in January 2025 directed agencies to stop work on establishing or issuing a CBDC. Separately, the Anti-CBDC Surveillance State Act passed the House in July 2025. An executive order can be reversed by the next administration. A statute is harder to undo. That distinction is the whole story of US CBDC policy and it's worth watching which one ends up governing.

Sweden's Riksbank ran an e-krona pilot for years and hasn't committed to issuing. The ECB's preparation phase continues and the legislation hasn't passed. The digital pound remains at the design stage with no decision to build.

Nothing is inevitable. Nothing is dead.

Commentary

What follows is opinion, not reporting.

The privacy concern is legitimate and the programmability concern is overstated in the near term but reasonable over a long horizon. Institutions change hands. The right question isn't whether the current designers intend anything sinister. It's whether the architecture makes a future abuse cheap, and a central ledger does make it cheaper than a world of cash and fragmented bank records.

The strongest defense of cash isn't a slogan about freedom. It's that a payment system with no offline, no-permission fallback has a single point of failure, and everyone learns this during an outage.

So the practical position is narrow. Support statutory protection for cash acceptance. Support a statute rather than an executive order if you want a US CBDC prohibition to mean anything. Read the holding limit, the remuneration decision and the offline design in any proposal before reacting to it, because those three parameters tell you what the thing is.

Don't confuse this with stablecoins

A dollar stablecoin is a private liability backed by reserves. A CBDC is a central bank liability. They're different instruments with different failure modes and different regulators. US policy in 2025 moved toward regulated private stablecoins while moving away from a government-issued retail digital dollar, which is a coherent choice whether or not you agree with it.

If you hold crypto, the thing that affects you is the stablecoin rulebook, not a digital pound that doesn't exist.

Keep some cash in the house anyway. That advice predates all of this and survives whichever way it goes.
