Global retail CBDC pilot comparison matrix — Africa, Caribbean, Asia, UK

Wiki route

This entry sits under fintech index as the cross-jurisdiction comparison matrix for the seven most-cited live or in-design retail CBDC programmes. It complements the per-jurisdiction deep dives at Nigeria eNaira, Bahamas Sand Dollar, Jamaica JAM-DEX, BoE digital pound consultation, and e-CNY supply-chain expansion by enabling side-by-side reading rather than narrative-by-narrative reading. For architecture context see CBDC multi-tier architecture overview, CBDC three operating paradigms, and four core trade-offs in CBDC architecture selection; for the four-country adoption curve see CBDC adoption curve 2026; for the wholesale-bridge layer see mBridge and BIS Project Agorá.

[!info] TL;DR Seven retail-CBDC programmes anchor the 2026-05 public dataset: Sand Dollar (Bahamas, live 2020-10, longest-running), e-CNY (China, live pilots from 2020-04, largest-by-registered-wallets), DCash (ECCB, pilot 2021-03, discontinued 2024-01), eNaira (Nigeria, live 2021-10, canonical adoption-failure case), JAM-DEX (Jamaica, live 2022-07, cleanest small-economy adoption), Bakong (Cambodia, live 2020-10, technically a payment-system + quasi-CBDC hybrid), and digital pound (UK, design phase since 2024, no decision to launch). Read across the matrix the structural pattern emerges: technology vendor choice (Bitt vs eCurrency Mint vs in-house) is downstream of distribution-incentive design, legal-tender status correlates with explicit legislative authorisation rather than market acceptance, and adoption percentage tracks distribution-channel-ownership (PBoC’s state-bank mandate, NCB Lynk anchor, vs Bahamas multi-AFI dilution, vs Nigeria DMB+MMO incentive misalignment).

Why a seven-pole comparison

The single-issuer narrative (“retail CBDCs are working in some places, failing in others”) is correct but unhelpful — it does not isolate which design choices drive which outcomes. By placing all seven programmes side-by-side on statute / issuance model / wallet model / KYC tiers / adoption / technology vendor / interoperability, the structural correlations become visible. The matrix view also shows the DCash discontinuation as not a one-off failure but the visible tail of a pattern (small-economy + multi-AFI + Bitt-vendor + no anchor wallet + no enrolment incentive) that also constrains Sand Dollar and eNaira. For the broader CBDC vs private-rail competitive backdrop see EM crypto dollarization pattern and gray-market dollar formalization.

Matrix A · Statute, regulator, launch status

The earliest mover is Bahamas (2020-10) nation-wide and e-CNY (2020-04) pilots; the latest live programme is JAM-DEX (2022-07). The only discontinued programme is DCash (2024-01) — a cautionary data point, since DCash used the same Bitt vendor as Sand Dollar and eNaira. The UK is the only programme of the seven not yet committed to launch. Note: e-CNY pilots predate the Sand Dollar’s nation-wide launch by ~6 months, but PBoC has not declared “national launch”; e-CNY remains in an extended-pilot phase covering 26+ cities.

Matrix B · Legal-tender status and currency anchor

The legal-tender split runs Jamaica > Bahamas > UK proposal > Nigeria > China > Cambodia > DCash. Jamaica’s BoJ Amendment Act 2022 is the cleanest dedicated-CBDC legislation; the UK would require primary legislation it has not yet introduced; China amended the PBoC Law in 2020; Nigeria leaned on pre-existing currency-issuance authority and is unique in never passing CBDC-specific legislation despite the eNaira being live for 4+ years.

Matrix C · Issuance and distribution model (direct vs intermediated)

Distribution-channel-ownership is the binding adoption variable. JAM-DEX’s Lynk and e-CNY’s state-bank mandate aligned distribution incentives; Sand Dollar’s interoperable-AFI model is structurally clean but dilutes any single AFI’s marketing incentive; eNaira’s DMB+MMO stack had universally weak incentives (DMBs see eNaira as cannibalising fees, MMOs see it competing with their own e-money); DCash discontinuation traces to the same dilution dynamic plus operational vulnerability. The UK PIP/ESIP design has not been launch-tested.

Matrix D · KYC tier structure and per-wallet limits

Tier-1 caps as inclusion-targeting: every live programme attempted a low-friction tier for the unbanked; no live programme reports tier-1 dominance — the IMF Working Papers on Sand Dollar and eNaira both note that tier-2 (ID-verified) users dominate actual usage. The inclusion design is structurally correct but did not bind on the unbanked at the scale targeted. The UK digital pound, uniquely, considers a per-person holding cap (£10K-£20K) instead of a tiered-KYC structure — this is the biggest single design divergence across the seven programmes.

Matrix E · Adoption metrics — registered vs active vs population

Cambodia Bakong is the outlier. Its 40-60% adoption figure reflects that Bakong is technically a payment-system + interoperability layer that absorbed the existing QR-payment market, not a pure central-bank-liability retail CBDC. The number is genuine on the payment-system reading but not directly comparable to Sand Dollar / eNaira / JAM-DEX adoption metrics. JAM-DEX is the cleanest small-economy success on a percentage-of-population basis among comparable pure-retail-CBDC peers. e-CNY is the largest absolute but small daily-active percentage, similar to the registered-vs-active gap in eNaira. DCash discontinuation is the only outright failure terminal-case.

Matrix F · Technology vendor and underlying tech

The Bitt vendor cluster (Sand Dollar / eNaira / DCash) covers three of the four worst adoption outcomes in the table. The eCurrency Mint deployment (JAM-DEX) is the cleanest small-economy outcome. In-house (e-CNY) and Soramitsu (Bakong) are the two non-Bitt/non-eCurrency Mint paths and both have stronger adoption — but with very different distribution models, so vendor choice is not the binding variable. The pattern is more “distribution design constrains vendor outcome reach” than “vendor capability determines adoption.” For more on the vendor / governance interaction see four core trade-offs in CBDC architecture selection.

Matrix G · Cross-border interoperability

Cross-border CBDC adoption is concentrated in two programmes: e-CNY (via mBridge + GBA HK link) and Bakong (via PromptPay + ASEAN QR). The five remaining retail-CBDC programmes (Sand Dollar, DCash, eNaira, JAM-DEX, digital pound) have no cross-border CBDC integration as of 2026-05. This is the largest single gap in the small-economy retail-CBDC story — Caribbean and West-African programmes that would most benefit from cross-border remittance corridors have no CBDC-level bridge.

Matrix H · Issuance ↔ distribution incentive alignment scorecard

The single most powerful predictor of adoption among the live programmes is whether a single anchor distributor or wallet has aligned commercial incentive to push the CBDC. Jamaica’s Lynk = NCB Financial Group commitment; China’s state-bank mandate + AliPay/WeChat absorption; Cambodia’s Bakong-as-payment-system network effect. The three weakest cases (DCash, eNaira, Sand Dollar) all fail this test for different reasons (operational fragility, incentive misalignment, and incentive dilution respectively).

Why these dimensions

The eight matrix axes (statute, legal tender, issuance model, KYC tiers, adoption, technology vendor, cross-border, incentive alignment) were chosen because they map directly to the gating variables in the BIS/IMF CBDC adoption literature:

1. Statute / legal tender — determines legal enforceability and acceptance ceiling (theoretical max market share).
2. Issuance / distribution — determines who gets paid for distribution (the binding rate-of-adoption variable).
3. KYC tiers — determines accessibility floor for the unbanked (theoretical inclusion ceiling).
4. Adoption % — measures realised outcome (the only metric the public cares about).
5. Technology vendor — determines operational risk (DCash failure tied to vendor-platform fragility under load).
6. Cross-border — determines whether the CBDC has any role beyond domestic payments.
7. Incentive alignment — predicts the rate-of-adoption variable better than any other single measure.

Statute and legal tender are necessary but not sufficient; incentive alignment is sufficient when present (JAM-DEX, e-CNY, Bakong) and decisive when absent (eNaira, DCash, Sand Dollar). This is the central empirical finding the matrix view reveals that a per-jurisdiction narrative obscures.

Reading the matrix

• The Bitt vendor cluster pattern: Sand Dollar, eNaira, DCash all used Bitt and all underperformed. The vendor is not the binding variable — distribution-incentive design is — but the vendor cluster correlation is striking enough that future small-economy programmes likely diversify vendors.
• The “first ever” vs “best outcome” divergence: Bahamas was first (2020-10-20 nation-wide) but JAM-DEX (2022-07) has the cleanest adoption percentage. Speed-to-launch does not predict adoption quality.
• DCash as the canonical failure: discontinued 2024-01 after a two-month outage in 2022 and persistent low adoption. The DCash post-mortem is now the most-cited case in the BIS CBDC operational-risk literature.
• e-CNY as the registered-vs-active gap: 180M+ registered wallets and single-digit-million daily active is a 25-50× gap; the same pattern (smaller in scale) is visible in eNaira. Registered wallets do not equal active users in any retail CBDC.
• digital pound as the indefinite-design-phase pattern: the BoE’s “design phase, not commitment to launch” framing is politically convenient and may keep the programme in design phase indefinitely without formally cancelling, mirroring the Riksbank’s e-krona path.
• Bakong as the payment-system-CBDC hybrid: Bakong achieves the highest adoption-percentage of any programme in the matrix precisely because it absorbed the existing QR-payment market rather than competing with it — an option not available to a pure CBDC that competes with existing payment rails (UK Faster Payments, Brazil Pix, India UPI).
