CBDCs.
Programmable government money, explained.

Section 1 · What a CBDC is

A Central Bank Digital Currency (CBDC) is a digital form of a country's official currency, issued and controlled directly by the central bank.

This is fundamentally different from:

• The dollars in your bank account. Those are a bank liability. The bank owes you dollars; the bank holds reserves at the Fed. You hold a claim on the bank.
• Bitcoin or other cryptocurrencies. No central issuer, no government backing, no programmable rules dictated by an authority.
• PayPal, Venmo, or Cash App. Private companies moving existing dollars between bank accounts.

A CBDC is government money going directly to citizens without commercial banks in the middle, at least in the retail-CBDC concept. The central bank issues the digital currency. The central bank can also write rules into how that currency works.

Section 2 · Who is building them

As of 2026, over 130 countries representing more than 98% of global GDP are exploring CBDCs verify×DON'T TRUST, VERIFYClaim: Over 130 countries representing more than 98% of global GDP are exploring CBDCs as of 2026.Verify at: Atlantic Council CBDC Tracker ↗ Source 1 in the list belowThe Atlantic Council maintains the most comprehensive public tracker of CBDC research, pilots, and launches..

Launched

• China (e-CNY, digital yuan): the largest live pilot. By end-November 2025, 230 million personal wallets had been opened through the e-CNY app, and cumulative transactions totaled 16.7 trillion yuan (PBoC figures reported by Xinhua, Dec 29, 2025) verify×DON'T TRUST, VERIFYClaim: By end-November 2025, 230 million personal wallets had been opened through the e-CNY app, and cumulative e-CNY transactions totaled 16.7 trillion yuan.Verify at: Xinhua, 数字人民币迎来重大调整 (Digital yuan undergoes major adjustment), Dec 29, 2025 ↗ Source 2 in the list belowPBoC publishes periodic statistics on e-CNY adoption.

It now reports wallets opened via the e-CNY app (180 million at end-July 2024, 230 million at end-November 2025), so the two figures are not directly comparable..
• Bahamas (Sand Dollar): launched 2020. The first CBDC live in a sovereign nation.
• Nigeria (eNaira): launched 2021. Adoption has been limited, though the eNaira remains live.
• Jamaica (JAM-DEX): launched 2022.
• Eastern Caribbean Currency Union (DCash): a regional CBDC across multiple Caribbean states.

Section 3 · What makes CBDCs different from current money

Programmability

Programmability is the feature most distinct from physical cash and from current bank money.

• Governments could program CBDCs to expire if not spent by a certain date, stimulating consumption directly.
• Governments could restrict CBDCs to specific spending categories: food but not alcohol, domestic goods but not imports, approved merchants but not others.
• Governments could implement automatic negative interest rates: your balance declines over time if you do not spend or invest.

None of these features exist in physical cash. CBDCs would make them technically possible.

Surveillance

Every CBDC transaction is visible to the issuing government. Physical cash transactions leave no record. Bank transactions leave records only at the bank, accessible to law enforcement through subpoena. A CBDC creates a complete transaction history for every citizen: who you paid, when, how much, for what.

Disintermediation

In a retail-CBDC model, citizens hold wallets directly with the central bank, no commercial bank required. This could make distributing stimulus payments, tax refunds, or benefits more efficient. It could also make freezing individual accounts easier; there is no commercial-bank intermediary to push back.

Section 4 · The case for CBDCs

The strongest arguments proponents make. These are real arguments. Dismissing them entirely misses the genuine inefficiencies in current payment systems that CBDCs could address.

• Bring unbanked populations into the financial system without requiring a commercial bank account.
• Reduce payment-processing costs by removing Visa and Mastercard interchange fees, which can be 1.5 to 3.5% on every retail card swipe.
• Speed up cross-border payments. Current SWIFT transfers take 1 to 5 days and cost meaningful fees; a well-designed CBDC could settle in minutes.
• Reduce money laundering and tax evasion through complete transaction visibility.
• Enable more precise monetary-policy implementation, including direct stimulus payments.

Section 5 · The case against

Financial surveillance

Complete transaction history available to the government has no precedent outside authoritarian systems. Even in democracies, the questions are: who controls the data, who can access it, under what legal standard, and with what oversight? The infrastructure does not distinguish between democratic and authoritarian governments. Once built, it is available to whoever holds power next.

Programmability risk

The same feature that could target stimulus to low-income households could target restrictions to political dissidents. Code is policy. Whoever writes the code writes the law. Expiring money or category-restricted money eliminates individual financial autonomy by design.

Banking-system disruption

If citizens move deposits from commercial banks to CBDC wallets, banks lose their funding base. Banks may need to raise deposit rates to compete or shrink their balance sheets. That reduces credit creation and lending capacity, which is how new business investment and home buying are financed.

Single point of failure

Current money is distributed across thousands of banks. A CBDC would concentrate the entire money supply in one government-controlled system. A successful cyberattack on that system would be catastrophic in a way that no bank-level attack ever could be.

Section 6 · CBDC vs Bitcoin

The comparison most relevant to this site:

The honest nuance

• Bitcoin is pseudonymous, not anonymous. Chain analysis can link addresses to identities once any address is associated with a real-world purchase.
• Some CBDC designs include privacy protections, though these are government promises rather than mathematical guarantees. Promises can be revoked by the next administration.
• Physical cash remains more private than either. The ongoing decline of cash use is itself part of why CBDCs are even on the table.

Section 7 · The US situation

The Federal Reserve's FedNow payment system (launched 2023) is not a CBDC. FedNow is an instant-payment rail between commercial banks, not a direct government-money product for citizens verify×DON'T TRUST, VERIFYClaim: FedNow is an interbank payment rail, not a CBDC.Verify at: Federal Reserve FedNow service page ↗ Source 5 in the list belowFedNow processes payments between commercial banks. Citizens still hold money at commercial banks; FedNow does not change that..

Congress has introduced legislation both proposing and prohibiting a US CBDC. The political situation as of 2026 is contested.

A US retail CBDC would require Congressional authorization. The Federal Reserve cannot launch one unilaterally. This is different from most other central banks, which have more unilateral authority.
