CBDC Adoption Patterns Will Track Institutional Trust

The three countries that have fully launched a retail CBDC—Bahamas, Jamaica, Nigeria—all show slow adoption, and Nigeria is the cleanest case. After four years, only 0.5% of the population uses the eNaira, 98.5% of wallets are inactive, and Nigerians have meanwhile moved roughly $59 billion through unauthorized stablecoins. The state could issue the eNaira; it could not manufacture the cultural legibility required to make it preferred.

The headline numbers for China's e-CNY are large—3.48 billion cumulative transactions, $2.37 trillion in volume by late 2025, 230 million individual wallets—and on the surface look like adoption at scale. They are not. Voluntary daily use remains low; most early users spent state-distributed promotional balances and stopped. Average wallet balances have been measured in single yuan. Citizens continue to prefer Alipay and WeChat Pay, which together hold roughly 90% of the mobile payment market. The PBOC's January 2026 reclassification of the e-CNY as interest-bearing deposit money was an institutional acknowledgment that voluntary adoption had stalled and required new incentives to compete with private incumbents. The relevant trust here is not general trust in the state but trust in the existing monetary rails as legible and adequate. Where the existing system already works, citizens stay with it.

The mandatory-rollout pattern is clearest in Russia, where the digital ruble began limited retail rollout in 2025 and is being phased in for government workers and welfare recipients through 2026. State payment channels are being moved onto the new instrument by administrative decision; voluntary citizen adoption outside the mandated channels remains uncertain. Brazil's Drex took a different turn—originally planned for a 2024 retail launch, the central bank scaled back retail ambitions and pivoted toward wholesale tokenization, a mid-trust society opting out of the retail CBDC ambition when technical and policy difficulties accumulated.

The high-trust cases support the marker from the other direction. The United States banned federal CBDC development by executive order in January 2025, with legislation reinforcing the ban passing the House in July 2025; the executive order cited surveillance, privacy, and sovereignty as grounds. Sweden's Riksbank, four-plus years into investigation, continues to defer; a 2023 government inquiry concluded there was insufficient social need. The Bank of Japan stated in June 2025 that it has no immediate plans for a digital yen. The Eurozone's digital euro project closed its preparation phase in October 2025 and is now targeted at potential issuance in 2029, contingent on 2026 legislation, with the project framed by European leaders as a monetary sovereignty response rather than a citizen-demand response. The one venue where CBDCs are doing meaningful volume—mBridge, the cross-border wholesale settlement network—is central-bank to central-bank, not citizen-to-merchant, and the marker is specifically about retail adoption.

Status reads as on-track. What would call this into question: mass voluntary uptake of a state-issued CBDC in a high-trust society, or organic citizen demand for the eNaira exceeding stablecoin alternatives in Nigeria. Neither is currently visible.
