Central Bank Digital Currencies: Global Adoption Accelerates as Pilots Move to Scale in 2026

Central Bank Digital Currencies (CBDCs) have moved from experimental projects to significant implementations in 2026, with several major economies launching retail CBDCs and many more advancing from pilot to scale phases. According to data from the Bank for International Settlements (BIS) and the Atlantic Council CBDC Tracker, 114 countries representing over 95% of global GDP are now exploring CBDCs (up from 81% in 2023), with 19 G20 economies in advanced stages of development.

The CBDC Landscape Evolution

Implementation Status (March 2026)

• Fully Launched Retail CBDCs: 4 countries (Bahamas, Jamaica, Nigeria, Eastern Caribbean Currency Union)
• Pilot Phase: 21 countries including China, Sweden, UAE, Singapore, Thailand
• Development Phase: 32 countries including Eurozone, UK, Canada, Brazil, India
• Research Phase: 25 countries including US, Japan, Switzerland, Saudi Arabia
• No Action: 18 countries

Wholesale CBDC Progress

• Live Wholesale Systems: 12 countries including Singapore (Project Ubin+), Saudi Arabia (Aber), Thailand (Project Inthanon)
• Pilot Projects: 18 countries including Eurozone (Project Luna), US (Project Cedar+), UK (Project Rosalind)
• Research Stage: 28 countries

"We're witnessing the most significant innovation in money since the transition from commodity to fiat currency," states Agustín Carstens, General Manager of the BIS. "CBDCs represent not just a new payment instrument but a potential reshaping of the monetary and financial system architecture."

Design Choices and Trade-offs

Architecture Models

Countries are adopting different technical approaches:

Account-Based vs Token-Based

• Account-Based: 68% of retail CBDC projects (China's e-CNY, Sweden's e-krona)

  • Central bank maintains ledger of all holdings
  • Similar to traditional bank accounts but direct central bank liability
  • Easier interest rate transmission and negative rates implementation
  • Privacy concerns due to traceability

• Token-Based: 32% of retail CBDC projects (Bahamas' Sand Dollar, Eastern Caribbean's DCash)

  • Digital tokens represent value, similar to physical cash
  • Can offer greater anonymity options
  • More complex to prevent double-spending without central oversight
  • Interest rate transmission requires wallet-level mechanisms

Direct vs Indirect (Intermediated) Models

• Direct Model: 41% of projects

  • Central bank handles all aspects: onboarding, KYC/AML, transaction processing
  • Greater control but higher operational burden on central bank
  • Examples: Bahamas, Eastern Caribbean

• Indirect Model: 59% of projects

  • Private sector intermediaries (banks, fintechs) handle customer-facing functions
  • Leverages existing infrastructure and expertise
  • Central bank focuses on settlement and monetary policy
  • Examples: China, Sweden, Eurozone design

Technology Foundations

• Distributed Ledger Technology (DLT): 45% of projects (particularly wholesale CBDCs)
• Centralized Systems: 55% of projects (majority of retail CBDCs)
• Hybrid Approaches: Growing interest in combining benefits of both approaches
• Programmability Features: 38% exploring smart contract capabilities for automated payments
