Globally, central banks have moved quickly. According to the Human Rights Foundation’s CBDC Tracker, more than 139 governments are researching, piloting, or assessing CBDCs, up from fewer than 40 in . In , IMF Managing Director Kristalina Georgieva summarized the trend clearly: fiat money is going digital, driven by the speed of crypto markets, tokenization, and modern payment systems. A OMFIF survey found that 72 percent of central banks expect to issue a CBDC, with about one third aiming to do so within five years.
Nigeria offers an early, practical case study. The eNaira was launched to improve payment efficiency, reduce cash handling, and expand financial inclusion. While adoption has been slower than initially hoped, the experience has been instructive. It showed that simply issuing a digital currency is not enough. Trust, ease of use, incentives, and compatibility with existing habits matter just as much as technology. For many Nigerians, stablecoins and mobile money apps have filled gaps that the eNaira has struggled to address, especially for cross-border payments and informal commerce.
China’s digital yuan shows how design choices continue to evolve. On , the e-CNY shifted from a digital cash model to a digital deposit structure. Verified wallets held through commercial banks began earning modest interest of about 0.05 percent annually. The People’s Bank of China framed this as a way to boost adoption by integrating the digital yuan into formal bank balance sheets backed by deposit insurance. By , cumulative transactions had reached 3.48 billion, totaling roughly 16.7 trillion yuan in value.
The United States has taken a different route. Rather than issuing a retail CBDC, it has focused on regulating privately issued dollar-backed stablecoins. On , the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act) created a federal framework requiring full reserve backing, regular disclosures, audits, and strict AML and KYC compliance. Additional state-level rules, including new licensing requirements in California effective , reinforce the U.S. preference for regulated private digital money rather than a state-issued alternative.
Europe sits somewhere in between. The European Central Bank completed its two-year preparation phase for the digital euro in and published a draft rulebook. A parliamentary decision is expected in the , with possible issuance by . Unlike China, the ECB has stressed that the digital euro should remain non-interest-bearing, functioning as digital cash rather than a competing savings instrument.
Outside government systems, stablecoins and cryptocurrencies continue to grow rapidly. Research from TRM Labs shows stablecoin transaction volume rose 83 percent between and , exceeding $4 trillion in the first seven months of . Visa estimates that cross-border payments settled in stablecoins reached about $5.7 trillion in . Institutional interest remains strong, with analysts projecting Bitcoin prices between $130,000 and $200,000 by the end of . Tokenization of real-world assets is also accelerating, with firms like BlackRock positioning it as a foundational shift in market infrastructure.
Together, these developments highlight a central tension. CBDCs prioritize state oversight, monetary control, and financial stability. Stablecoins emphasize regulatory clarity and global usability. Decentralized cryptocurrencies focus on openness, programmability, and access to yields that traditional banking rarely offers. In decentralized finance, lending and staking platforms averaged yields of about 8.2 percent in , far above most retail savings accounts.
Uncertainty remains. Regulations differ widely across borders, complicating interoperability. Consumer protection mechanisms for stablecoins are still being refined. The long-term impact of interest-bearing CBDCs, including China’s approach, is unproven. Nigeria’s eNaira experience underscores that adoption depends as much on incentives and real-world utility as on policy intent.
What is clear is the direction. Digital money is becoming part of everyday financial infrastructure. Initiatives like the BIS Innovation Hub’s Project Nexus, expected to advance in , aim to connect national payment systems while respecting local rules. The International Monetary Fund continues expanding its CBDC Virtual Handbook to guide policymakers through these trade-offs.
For individuals and businesses, this is no longer abstract. Understanding the differences between CBDCs, regulated stablecoins, and decentralized assets now affects payments, savings, and cross-border transactions. In , digital money is not a future experiment. It is infrastructure being shaped in real time.
