How Central Bank Digital Currencies Could Reshape Money

130 Countries Exploring Digital Cash—And Not One Has Figured It Out

As of late 2024, 134 countries representing 98% of global GDP were actively researching, developing, or piloting central bank digital currencies, according to the Atlantic Council's CBDC Tracker. Eleven countries had fully launched a CBDC, led by Nigeria's eNaira and the Bahamas' Sand Dollar. China's digital yuan (e-CNY) had processed over $250 billion in transactions across 26 pilot cities. The European Central Bank was deep into the preparation phase for a digital euro. Yet the United States, issuer of the world's reserve currency, remained in the research stage with no firm launch timeline. The gap between ambition and implementation reveals that creating digital government money is far more complex than the technology alone.

What a CBDC Actually Is

A CBDC is a digital form of a country's fiat currency, issued and backed by the central bank. It is not cryptocurrency. The distinction matters.

Wholesale vs. Retail CBDCs

Two fundamentally different architectures exist, targeting different users and purposes.

Wholesale CBDCs are restricted to financial institutions. Banks use them to settle interbank transactions—replacing or supplementing existing real-time gross settlement systems. The Bank of France, Swiss National Bank, and Monetary Authority of Singapore have conducted successful wholesale CBDC experiments.

Retail CBDCs are available to the general public—digital cash that individuals and businesses can hold in wallets, spend at merchants, and transfer to each other. Retail CBDCs are where the policy debates concentrate because they directly affect citizens.

• Retail CBDCs could provide unbanked populations with government-backed digital wallets (1.4 billion adults globally lack bank accounts)
• Government stimulus payments could reach recipients instantly—no checks, no bank processing delays
• Programmable money could enable automatic tax collection or expiring stimulus that must be spent within a timeframe
• Cross-border payments—currently slow and expensive—could settle in seconds between CBDC-equipped nations

China's Digital Yuan: The Largest Experiment

China launched e-CNY pilot programs in 2020 and has expanded them steadily. By mid-2024, the digital yuan had been used for over $250 billion in cumulative transactions across 26 cities. Government employees in pilot cities receive portions of their salary in e-CNY. Merchants are incentivized to accept it through lottery promotions and subsidies.

The digital yuan's controlled anonymity model represents Beijing's answer to the privacy question: small cash-like transactions remain private, but the government retains the ability to trace large flows for anti-money-laundering and tax enforcement. Western democracies view this model with suspicion.

The Digital Euro Project

The European Central Bank entered its "preparation phase" for a digital euro in November 2023, targeting a potential launch no earlier than 2028. The design priorities reflect European values: strong privacy protections, offline functionality, and free basic use for consumers. Holdings would be capped—possibly at €3,000 per person—to prevent bank runs during financial crises.

The ECB has emphasized that a digital euro would complement cash, not replace it. The European Parliament is drafting legislation to ensure cash remains legal tender indefinitely. This dual approach addresses concerns from civil liberties organizations and older populations less comfortable with digital-only transactions.

The Disintermediation Risk

If citizens can hold money directly at the central bank via a CBDC, why keep deposits at commercial banks? This question terrifies bankers and fascinates economists.

• During a financial crisis, depositors could instantly move money from a commercial bank to a CBDC wallet—a digital bank run faster than any in history
• If deposits leave banks, banks have less money to lend, potentially contracting credit and slowing economic growth
• Central banks might need to become direct lenders to businesses and consumers—a role they're not designed for
• Holding limits and zero-interest CBDC designs are specifically intended to mitigate this risk

Every CBDC design involves tradeoffs between financial stability, monetary policy effectiveness, privacy, and financial inclusion. No country has found the perfect balance.

Privacy: The Unresolved Tension

Cash is anonymous. Every physical dollar bill changes hands without creating a record. A CBDC could replicate this anonymity—but governments have little incentive to design untraceable digital money when traceable money helps fight tax evasion, money laundering, terrorism financing, and sanctions violations.

The European Central Bank has proposed a tiered privacy model where transactions below a threshold (possibly €300) leave no digital trail, while larger transactions are visible to compliance systems. The U.S. Federal Reserve has stated it would not pursue a CBDC without explicit Congressional authorization and robust privacy protections—a position that reflects both genuine privacy concerns and political resistance to expanding government financial surveillance.

The Geopolitical Dimension

CBDCs are not just monetary tools. They are instruments of geopolitical influence. China's digital yuan could facilitate trade settlements that bypass the U.S. dollar and, by extension, U.S. financial sanctions. The mBridge project—a cross-border CBDC platform connecting China, Thailand, the UAE, Saudi Arabia, and Hong Kong—processed $22 million in real transactions during its 2022 pilot. If successful at scale, it could reduce dependence on the SWIFT messaging system that the U.S. leveraged to sanction Russia after its invasion of Ukraine.

The race to deploy CBDCs is ultimately a race to define the future architecture of money—who controls it, who sees it, and who can be excluded from it.
