CBDC Privacy Concerns: What Governments Aren’t Telling You
Central bank digital currencies are coming. Over 130 countries are working on them. The pitch sounds reasonable: faster payments, financial inclusion, modernizing money.
But there’s something most governments don’t emphasize: CBDCs give the state unprecedented visibility into how you spend your money. Every transaction. Every purchase. Recorded forever.
This isn’t conspiracy thinking. It’s the architecture.
💡 Key Takeaways
- CBDCs are government-issued digital currencies, not cryptocurrencies
- Most CBDC designs give central banks direct access to transaction data
- “Programmable money” means your spending can be restricted or controlled
- China’s e-CNY already imposes spending limits and tracks all transactions
- Privacy-preserving alternatives like Zcash exist for those who want financial freedom
What Are CBDCs?
A Central Bank Digital Currency is digital money issued by a central bank. Think of it as a digital version of cash, except it isn’t really like cash at all.
Cash is anonymous. You hand someone a bill. No record exists. The transaction ends.
CBDCs are the opposite. Every transaction can be recorded. The central bank sees the flow of funds. Depending on the design, they might see every purchase you make.
CBDCs vs Cryptocurrency
People sometimes confuse CBDCs with cryptocurrency. They’re fundamentally different:
| Feature | CBDCs | Bitcoin/Zcash |
|---|---|---|
| Issuer | Central bank (government) | Decentralized network |
| Control | Centralized | No single controller |
| Supply | Central bank decides | Fixed by protocol |
| Surveillance | Built into design | Bitcoin public; Zcash optional privacy |
| Programmability | Government can restrict | User controls their money |
CBDCs give governments more control over money. Cryptocurrencies take control away from governments and give it to individuals.
The Surveillance Risk
Here’s what makes CBDCs different from existing digital payments.
When you use a credit card, your bank sees the transaction. Visa processes it. The merchant gets paid. Multiple private companies have partial information.
With a CBDC, the central bank can potentially see everything. One entity. Complete visibility. Every transaction you ever make, aggregated in one database.
Why This Matters
You might think: “I have nothing to hide.”
Consider what complete financial surveillance enables:
Profiling. Your spending patterns reveal your politics, your health, your relationships, your beliefs. You bought books on organizing protests? Visited a therapist? Donated to a controversial cause? All recorded.
Discrimination. Insurance companies could adjust rates based on your eating habits. Employers could screen you based on how you spend. Landlords could judge you by where you shop.
Control. A government that doesn’t like what you’re doing can simply turn off your ability to spend. No court order needed. Just freeze the account.
This already happened. In Canada in 2022, the government froze bank accounts of people who donated to the trucker convoy protests. Roughly 200 accounts totaling C$7.8 million were frozen without court orders. A federal judge later ruled the action was “unreasonable and ultra vires.”
Now imagine that power built directly into the money itself.
⚠️ Not Hypothetical
China’s e-CNY already features tiered wallets with spending limits, mandatory identity verification for larger transactions, and direct central bank access to all transaction data. The infrastructure for financial surveillance exists today.
Programmable Money: The Real Danger
CBDCs aren’t just trackable. They’re programmable.
What does that mean? The central bank can set rules about how money is spent.
Examples of Programmability
Spending limits. China’s e-CNY already does this. Low-verification wallets cap at 2,000 yuan per transaction and 5,000 yuan per day. Higher limits require full identity verification.
Expiration dates. Money could expire if not spent by a certain date. Stimulus payments that must be used within 90 days. Savings discouraged by design.
Category restrictions. Your CBDC could be blocked from certain purchases. No alcohol. No gambling. No donations to organizations the government dislikes.
Geographic restrictions. Money that only works in certain areas. Welfare payments that can’t be spent outside your district.
Social credit integration. China is reportedly exploring linking e-CNY access to social credit scores. Low score? Limited spending ability. This isn’t paranoia. Government documents describe this integration.
Who Controls the Rules?
Here’s the question nobody asks: who decides what’s “allowed”?
Today it might be obvious restrictions. Tomorrow it might be carbon budgets. Or political speech. Or religious donations. Or support for opposition candidates.
The point isn’t whether current governments would abuse this power. The point is that the power exists at all. And once built, it doesn’t go away when administrations change.

Research and Development
137 countries representing 98% of global GDP are exploring CBDCs. In 2020, that number was 35.
United States
In July 2025, Congress passed the Anti-CBDC Surveillance State Act, prohibiting the Federal Reserve from issuing a retail CBDC directly to the public. The U.S. has instead focused on regulating private stablecoins.
This represents a rare instance of preemptive resistance to financial surveillance infrastructure.
Case Study: China’s e-CNY
China’s digital yuan is the most developed CBDC and the clearest preview of what surveillance money looks like.
The Architecture
The e-CNY uses a two-tier system. The central bank issues currency to commercial banks, which distribute it to users. But unlike traditional banking, the People’s Bank of China maintains visibility into all transactions.
Key features:
Tiered wallets. Full identity verification unlocks higher spending limits. Anonymous transactions are capped at small amounts.
Mandatory tracking. Even “anonymous” wallets require a phone number, which in China links to real identity through SIM card registration.
Spending controls. Wallet holders can create sub-wallets with spending limits and conditions. The government can implement similar controls at the system level.
Integration potential. The e-CNY architecture allows for integration with other government systems, including social credit.
What This Means
A Human Rights Foundation analysis concluded that the e-CNY gives the Chinese Communist Party “unparalleled insight into the Chinese people’s finances and significant levers to carry out punitive state action.”
The e-CNY isn’t a payment system. It’s a control system that happens to process payments.
ℹ️ Managed Anonymity
China calls its approach “managed anonymity.” Small transactions get some privacy. But the central bank retains the ability to trace any transaction when it wants to. Privacy exists at the government’s discretion, not as a right.
The Privacy Trade-offs
CBDC proponents argue there are legitimate reasons for transaction visibility.
The Arguments For Surveillance
Anti-money laundering. Tracking transactions helps catch criminals and terrorists.
Tax compliance. Visible transactions make tax evasion harder.
Fraud prevention. Suspicious patterns can be flagged and stopped.
Financial stability. Central banks need data to understand the economy.
Why These Arguments Fall Short
The problem isn’t that these goals are illegitimate. It’s that CBDC surveillance is disproportionate.
Cash already exists for anonymous transactions. Criminals use it. Most cash users are not criminals. The existence of privacy doesn’t prevent law enforcement from catching criminals through investigation.
CBDCs replace a system where privacy is the default with one where surveillance is the default. That’s a fundamental shift in the relationship between citizens and the state.
And here’s what the surveillance advocates never mention: existing anti-money-laundering systems already catch significant criminal activity. Banks already file suspicious activity reports. The current system isn’t perfect, but it doesn’t require universal surveillance of all citizens.
The European Approach: Privacy Theater?
The European Central Bank claims the digital euro will include privacy protections.
Promised Features
- Offline transactions with “cash-like” privacy for small amounts
- No direct central bank access to individual transaction data
- Limits on data retention by payment processors
The Concerns
Privacy advocates remain skeptical:
Conditional privacy. The proposed privacy only applies to small, offline transactions. Online transactions and larger amounts remain fully visible.
Law enforcement access. Even “private” transactions can be traced when authorities request it. Privacy exists until someone decides it shouldn’t.
Mission creep. Rules can change. What’s private today may not be tomorrow. Once the infrastructure exists, expanding surveillance becomes a policy choice, not a technical limitation.
During the ECB’s public consultation, 41% of all comments focused on privacy concerns. Europeans clearly worry about this. It’s unclear whether those concerns will translate into genuinely private money.
The Alternative: Privacy-Preserving Cryptocurrency
CBDCs represent one vision of digital money: state-controlled, surveilled, programmable.
Cryptocurrency represents another vision: decentralized, private (in some cases), owned by the user.
Why Zcash Matters in a CBDC World
Zcash uses zero-knowledge proofs to enable truly private transactions. Not “managed anonymity” where the central bank can look when it wants to. Mathematical privacy that no one can break.
With Zcash shielded transactions:
- No one sees who sent money
- No one sees who received it
- No one sees the amount
- The network verifies validity without revealing data
This isn’t about hiding crimes. It’s about maintaining the privacy that cash provided before everything went digital.
The Choice
The next decade will determine whether digital money means surveillance or freedom.
CBDCs offer convenience at the cost of privacy. Every transaction recorded. Spending potentially controlled. Your financial life visible to the state.
Privacy cryptocurrencies offer an exit. Money that works like digital cash. Spend what you want. Where you want. Without asking permission.
Both will exist. The question is which one you’ll use.
Protecting Your Financial Privacy
Short-term
Use cash while you can. Cash remains anonymous. Use it for transactions where privacy matters.
Limit digital payment data. Every card swipe creates a record. Be intentional about what you want tracked.
Learn about privacy tools. Understand how Zcash, Monero, and other privacy technologies work before you need them.
Long-term
Self-custody cryptocurrency. Hold some value in cryptocurrency you control. Not on exchanges. In your own wallet.
Support privacy legislation. Some jurisdictions are pushing back against surveillance. Support them.
Normalize privacy. The more people use privacy tools, the less suspicious privacy becomes. Use shielded transactions even when you “don’t need to.”
✅ Privacy Is Not Suspicious
Using privacy tools is not evidence of wrongdoing. Cash is private. Encryption is legal. Financial privacy is a human right recognized in international law. You don’t need to justify wanting privacy.
Frequently Asked Questions
Are CBDCs the same as cryptocurrency?
No. CBDCs are centralized government money. Cryptocurrencies are decentralized.
CBDCs are controlled by central banks. They can change the rules, freeze accounts, and monitor transactions.
Cryptocurrencies like Bitcoin and Zcash are controlled by protocol. No single entity can change the rules or freeze your funds.
CBDCs are the government’s vision of digital money. Cryptocurrency is the alternative.
Will CBDCs replace cash?
This is the concern. CBDCs could accelerate the decline of cash, leaving citizens with no anonymous payment option.
Some central banks claim CBDCs will complement cash, not replace it. But the trend is clear: cash usage is declining globally. Once a critical mass of transactions moves to CBDCs, maintaining cash infrastructure becomes expensive.
Sweden, a pioneer in cashless payments, is now requiring businesses to accept cash, recognizing the danger of eliminating it entirely.
Can I avoid CBDCs?
Possibly, depending on your jurisdiction.
Options include:
- Using cash while available
- Using decentralized cryptocurrency
- Using peer-to-peer transactions
- Living in jurisdictions that haven’t implemented CBDCs
However, if CBDCs become mandatory for tax payments, government benefits, or business transactions, avoiding them entirely becomes difficult.
The best protection is building alternatives before you need them.
Why should I care if I have nothing to hide?
Because privacy isn’t about hiding crimes. It’s about autonomy.
Do you want your insurance company knowing your diet? Your employer knowing your politics? Your landlord knowing where you shop?
Do you want a future government, whose values you might not share, having a complete record of every financial decision you ever made?
Privacy isn’t about hiding. It’s about controlling who knows what about you. Once you lose that control, you don’t get it back.
Are any CBDCs actually private?
Some central banks claim to offer privacy features. Examine these claims carefully.
“Privacy” in CBDC context usually means:
- Limited privacy for small transactions
- Privacy from other users, not from the central bank
- Privacy that can be overridden by law enforcement
This is not the same as mathematical privacy where no one can see your transactions.
True privacy means no one can trace your transaction, including the issuer. No CBDC offers this.
Conclusion: The Infrastructure Matters
The debate about CBDCs isn’t really about convenience or financial inclusion. It’s about what kind of infrastructure we build for the next century.
Build surveillance infrastructure and surveillance will happen. Maybe not today. Maybe not by your preferred government. But eventually.
Build privacy infrastructure and privacy becomes possible. Not guaranteed. But possible.
CBDCs represent a choice to build surveillance into the foundation of money itself. Once built, that infrastructure doesn’t go away. It just waits for someone to use it.
The alternative exists. Privacy cryptocurrencies like Zcash prove that digital money doesn’t require surveillance. The math works. The technology is here.
The question is whether enough people will choose it before the choice is made for them.
