Two Visions of Digital Money

By 2026 there is a real political contest underway over the future of digital money. Two competing visions are now actively in field deployment, and the choice between them has direct consequences for privacy, financial autonomy, and the relationship between citizens and states. **Vision 1: Central Bank Digital Currencies (CBDCs).** Sovereign-issued digital money, issued directly by a central bank and accessible to citizens through a state-controlled or state-licensed interface. Examples in actual deployment include China's e-CNY (digital yuan), Nigeria's eNaira, the Bahamas' Sand Dollar, India's e-Rupee, and the Eastern Caribbean's DCash. The European Central Bank is in the preparation phase for a Digital Euro. The Bank for International Settlements (BIS) is coordinating multi-CBDC settlement experiments via Project Agora and mBridge. **Vision 2: Private regulated stablecoins.** Privately-issued dollar (or other currency) tokens, fully backed by reserve assets, operating on public or permissioned blockchains, used directly by citizens via wallets. Examples include USDC, USDT, USDS, PYUSD, FDUSD. Regulatory frameworks like MiCA and the US GENIUS Act define the rules for these instruments to operate as legitimate payment infrastructure. The two models look superficially similar to a non-technical observer — both are "digital money on a phone" — but they differ profoundly in who issues them, who controls them, what they enable, and what they prevent. This lesson walks through the major CBDC deployments, the EU and BIS efforts, the explicit US anti-retail-CBDC stance under the Trump administration, and the structural reason this contest matters: programmability. State money can do things private money will not, and the question is whether you think that capability is good or bad.

Key terms

CBDC (Central Bank Digital Currency): Digital money issued directly by a central bank as a liability of the state, distinct from privately-issued stablecoins or commercial bank deposits. Can be wholesale (interbank) or retail (citizen-accessible).
e-CNY (Digital Yuan): China's CBDC, developed by the People's Bank of China starting around 2014. Cumulative transaction volume reached approximately 1.8 trillion yuan (~$250B) by mid-2024 and continues to grow. Most advanced major-economy CBDC pilot.
eNaira: Nigerian CBDC launched October 25, 2021 by the Central Bank of Nigeria. Adoption has been disappointing — low single-digit percentages of population — even as Nigerian stablecoin (USDT, USDC) usage flourished.
Sand Dollar: The Bahamas' CBDC launched October 20, 2020, the first formal CBDC launched by any sovereign country. Modest absolute adoption but high relative to population given the Bahamas' small size.
Digital Rupee (e₹): India's CBDC, with retail pilot launched December 1, 2022 (wholesale pilot November 2022). Reached over 1 million daily transactions in pilot zones by 2024-2025. Integrated with UPI QR codes for cross-rail payments.
Digital Euro: European Central Bank's proposed CBDC, in preparation phase since November 2023. Designed as a public alternative to private payments with holding limits to prevent bank disintermediation. Possible launch decision 2025-2026; politically contested.
Project Agora: BIS-led multi-CBDC settlement experiment launched April 2024 involving central banks of France, Japan, South Korea, Mexico, Switzerland, the UK, and the New York Fed plus private partners. Explores cross-border wholesale CBDC settlement. Notably excludes China and Russia.
mBridge: Multi-CBDC bridge project involving China, Hong Kong, Thailand, and UAE central banks. BIS stepped back from mBridge in late 2024 amid geopolitical considerations. Represents the China-aligned wing of CBDC cross-border infrastructure.
Executive Order 14178: Signed by President Trump on January 23, 2025, "Strengthening American Leadership in Digital Financial Technology" — explicitly prohibits establishment, issuance, or promotion of a US CBDC, dissolved the Biden-era digital asset working group, and codified US preference for private regulated stablecoins.
Programmability: The capacity for digital money to have rules embedded in or attached to specific units — expiry, category restrictions, automatic tax deduction, conditional spending, address-level freezes. Far more powerful for state CBDCs than for private stablecoins; absent from Bitcoin entirely.
