134 countries representing 98% of global GDP are exploring CBDCs. China's e-CNY has millions of users and works offline. The Bahamas issued the first live retail CBDC in 2020. mBridge settles cross-border payments between four countries in real time. The question is not whether money will be digital. It already is. The question is who controls the code — and what that means for freedom, inclusion, sovereignty, and the future of finance.

Before we explain what CBDCs are and why they matter, we need to understand what money actually is — because the confusion about CBDCs largely stems from a confusion about money itself. Money is not a commodity. It is not intrinsically valuable. A banknote is a piece of cotton and linen fibre that costs a few cents to produce and is worth the number printed on it only because everyone agrees that it is. Gold was money not because gold is useful (it mostly isn't) but because everyone agreed to treat it as a store of value and medium of exchange. Money is a technology for encoding social trust at scale. Every innovation in monetary history has been an innovation in how that trust is encoded, who encodes it, and who verifies it.
The confusion around CBDCs begins with the term itself. A Central Bank Digital Currency is not one instrument — it is a category that encompasses fundamentally different designs serving fundamentally different purposes. Understanding the three types is the prerequisite for understanding the projects, the benefits, and the risks.
Direct digital cash — a digital banknote issued by the central bank and held directly by individuals and businesses. Works like physical cash but exists in a digital wallet. Examples: China's e-CNY, Bahamas Sand Dollar, Jamaica JAM-DEX, Eastern Caribbean DCash. The most impactful for financial inclusion. The most politically sensitive for privacy.
Digital central bank money for use between financial institutions — banks settling transactions with each other and with the central bank. Not held by individuals. Examples: BIS mBridge, Swiss Helvetia, Singapore Project Orchid. Lower political risk. Higher immediate efficiency gains. The natural first step for most advanced economies.
Multi-currency platforms where multiple central banks' digital currencies interoperate for real-time international settlement. Examples: mBridge (China, Hong Kong, Thailand, UAE), Nexus (Singapore-led), Project Mariana (BIS). The most transformative for global trade finance. The most geopolitically significant — potentially challenging dollar dominance in correspondent banking.
CBDCs with built-in conditions — a government transfer that can only be spent on food, not alcohol; a business loan that automatically repays when invoices are paid; a tax payment that settles instantly when income is earned. Not a separate type but a capability that CBDCs enable. The most powerful feature. The most philosophically controversial — money that tells you how to spend it.
The most advanced retail CBDC in the world by scale. The People's Bank of China launched pilot programmes in 2020, expanded to over 20 major cities, and used the 2022 Beijing Winter Olympics and 2024 Paris Olympics as global showcase events. The e-CNY uses a two-tier model: the PBoC issues digital yuan to commercial banks and payment platforms (Alipay, WeChat Pay), who then distribute to users. Crucially, it works offline — near-field communication (NFC) allows payments even without internet connectivity, addressing the digital divide. Foreign visitors can use e-CNY wallets without a Chinese bank account.
The programmability is where e-CNY becomes geopolitically significant. Government welfare payments can be programmed with expiry dates — use it in 60 days or lose it, stimulating consumption. Regional usage restrictions ensure money is spent locally. Sector restrictions channel spending to approved categories. This programmability makes e-CNY the world's most powerful fiscal transmission mechanism — but also its most watched surveillance concern. China has processed hundreds of billions in e-CNY transactions. The scale is real. The adoption is real. The strategic intent — to reduce dependence on the dollar in international trade and to extend yuan influence — is also real.
The world's first live retail CBDC, launched October 2020 by the Central Bank of the Bahamas. The impetus was specific to the Bahamian context: an archipelago of 700 islands with 390,000 people, where moving physical cash between islands is expensive and slow, and where significant populations lack bank account access. Sand Dollar addressed a concrete problem rather than a theoretical one — and that specificity is why it works.
Privacy was built into the design: Sand Dollar wallets have transaction limits that reduce the KYC (Know Your Customer) requirements for small amounts, making it genuinely accessible to unbanked citizens. Merchants and individuals transact via a mobile app with no bank account required. The wallets are held by authorised financial institutions — a two-tier model similar to China's. Sand Dollar's lesson for the world: a CBDC designed to solve a specific, clearly articulated problem for a specific population will succeed. A CBDC designed to demonstrate technological capability will not. The Bahamas did not launch a CBDC to compete with China or to pioneer monetary innovation. It launched one because its citizens needed a better payment system and this was the best way to deliver it.
The Eastern Caribbean Currency Union's DCash — issued by the Eastern Caribbean Central Bank (ECCB) — is the world's first live multi-country retail CBDC, serving eight island nations: Antigua and Barbuda, Dominica, Grenada, Montserrat, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, and Anguilla. DCash was designed to reduce the cost of remittances between islands (previously high), reduce cash handling costs for merchants and banks, and improve financial inclusion in small island economies where traditional banking is expensive relative to average incomes.
DCash experienced a technical outage in early 2022 — an important stress test that revealed the resilience requirements for CBDC infrastructure. The ECCB managed the outage, restored the system, and continued. The lesson: CBDC systems must be designed for resilience, not just performance, because downtime is a failure of public trust, not just a technical inconvenience. DCash has since stabilised and expanded. Its most significant innovation is demonstrating that a CBDC can operate across multiple sovereign jurisdictions sharing a common currency — a template that has implications for the EU digital euro and for ASEAN digital currency integration.
mBridge is the most important wholesale CBDC project in the world — and the most geopolitically significant. Launched under BIS Innovation Hub coordination with the central banks of China, Hong Kong, Thailand, and the UAE, mBridge enables real-time, peer-to-peer cross-border payments between participating central banks without correspondent banking intermediaries. The minimum viable product (MVP) was declared in June 2024, with live transactions settling in minutes rather than the 3–5 days that traditional correspondent banking requires.
The geopolitical significance is direct: mBridge enables China, the UAE, and Thailand to settle trade transactions in their own currencies — bypassing the dollar correspondent banking system that currently processes most international trade. For countries that face US sanctions risk or simply wish to reduce dollar dependency, mBridge is the most technically credible alternative payment architecture yet developed. Saudi Arabia and Brazil have joined as observer members. Russia has expressed interest. The US response has been notably cautious — the Federal Reserve has not joined mBridge, and the US Treasury has flagged concerns about sanctions evasion risk. mBridge is simultaneously a payments efficiency project and a geopolitical infrastructure project — and which of those descriptions you emphasise depends entirely on which side of the dollar system you are on.
Switzerland's Project Helvetia is the most technically sophisticated wholesale CBDC in live production. The Swiss National Bank issues wholesale CBDC — CHF — on a distributed ledger platform (SIX Digital Exchange, SDX) for the settlement of tokenised financial assets: bonds, equities, and other instruments that have been issued as digital tokens on the same platform. Helvetia solves what is called the "delivery versus payment" problem in securities settlement: when you buy a bond, the bond and the payment traditionally settle on different systems with timing risk. Helvetia makes them settle simultaneously on the same ledger, in real time, with no settlement risk.
Major Swiss banks (UBS, Credit Suisse/UBS, Zürcher Kantonalbank) have transacted on the platform. The SNB has confirmed it as a live production system, not a pilot. Helvetia's narrow scope — wholesale only, securities settlement only — is precisely its strength. It solves a specific, technically clear problem with no political controversy about surveillance or privacy. Switzerland has demonstrated that a central bank can issue digital money on a distributed ledger for institutional use and that the financial system benefits immediately. This is the template for wholesale CBDCs globally.
1.4 billion adults globally remain unbanked. A CBDC wallet requires a smartphone and a national identity number — not a credit history, a minimum balance, or a bank branch nearby. The Bahamas, ECCB, and Jamaica have demonstrated that CBDC can reach populations that traditional banking excludes. For India, Indonesia, Nigeria, and dozens of other countries with large unbanked populations, this is the most compelling use case.
The global average remittance cost is 6.2% of the transferred amount — a toll on the most financially vulnerable families in the world. CBDC cross-border platforms like mBridge can settle in seconds at near-zero cost. The World Bank estimates that reducing remittance costs to 3% would save $20 billion annually. For families in the Philippines, India, Mexico, and Egypt who depend on remittances, this is not an abstract efficiency gain — it is food on the table.
Cross-border payments currently take 3–5 business days through correspondent banking chains with multiple intermediaries each extracting fees. Wholesale CBDCs settle in seconds with no intermediary and near-zero cost. Global trade finance — $12.4 trillion in annual cross-border flows — could be transformed. Project Helvetia's simultaneous delivery-versus-payment eliminates settlement risk that currently requires trillions in capital buffers across the financial system.
Negative interest rates are ineffective with physical cash — you simply withdraw and hold cash rather than pay the bank to keep your money. A CBDC can apply negative rates directly to digital holdings, making monetary policy more precise. Programmable stimulus with time limits ensures spending velocity. Direct transfers to citizens replace slow, leaky welfare systems. Central banks gain tools they have never had.
Approximately $2 trillion in illicit funds are laundered globally each year — largely through cash and correspondent banking opacity. A CBDC creates an immutable audit trail for every transaction. Tax evasion becomes structurally harder. Money laundering requires defeating the ledger rather than just moving cash. Corruption in government procurement can be tracked from payment to payee automatically. The compliance benefits are significant.
Countries whose populations use private digital payment systems (Alipay, M-Pesa, PayPal) are increasingly dependent on private corporations for core monetary infrastructure. A CBDC gives the state back its monetary sovereignty — the ability to operate the payment system without dependence on a private intermediary. For countries concerned about dollarisation, private stablecoin adoption, or cryptocurrency replacing local currency, a CBDC is the defensive response.
The privacy-efficiency trade-off is the central unresolved tension in CBDC design. The features that make CBDCs most useful for governments — transparency, programmability, traceability — are precisely the features that make them most threatening to individual freedom. China's e-CNY optimises for government visibility at the cost of individual privacy. The Bahamas Sand Dollar attempts to protect privacy through transaction limits and tiered KYC. The EU digital euro proposals have been significantly revised in response to European Parliament concerns about surveillance. There is no design that maximises both. Every CBDC is a political choice about where on the privacy-transparency spectrum a society should sit.
Bank disintermediation is the systemic risk that most CBDC designs have not adequately solved. If citizens can hold digital central bank money directly, why would they hold commercial bank deposits? Banks use deposits as the funding base for loans. If deposits migrate to CBDC wallets, banks either cannot make loans (credit crunch) or must find more expensive funding sources (higher lending rates). The two-tier model — where CBDCs are distributed through commercial banks — partially addresses this, but the fundamental tension remains: the better a retail CBDC is at serving citizens, the more it threatens the commercial banking system that currently serves them.
The geopolitical dimension of mBridge and cross-border CBDCs is the most consequential and least discussed risk. The dollar's role as the world's reserve currency gives the United States extraordinary geopolitical power — the ability to sanction countries by cutting them off from SWIFT and dollar correspondent banking. A world in which mBridge enables China, Russia, Iran, and their trading partners to settle transactions in their own currencies — outside the dollar system — is a world in which US sanctions power is substantially reduced. This is not a neutral technical development. It is a geopolitical architecture shift of the first order — and the countries building cross-border CBDC platforms know exactly what they are doing.
