Caribbean digital-currency rollout is now four years into its post-launch operational phase, with JAM-DEX as the first regional case study and a quiet shift across other islands in the design phase. This piece walks through what JAM-DEX actually achieved at the merchant level, what worked, what did not, and what the next wave of caribbean cbdc adoption will need to fix to land more decisively.
JAM-DEX — the Jamaica Digital Exchange — launched in 2022 as the first central-bank digital currency (CBDC) issued in the Caribbean. It was a wallet-based digital currency, backed one-to-one by the Jamaican dollar, with the Bank of Jamaica as the issuer and a network of authorized wallet providers as the distribution layer.
The promise at launch was significant: a reduction in cash-handling friction across Jamaican commerce, particularly for the unbanked and underbanked, a substitute for the costlier card-payment rails, and a regional precedent that other Caribbean monetary authorities could replicate.
Four years in, the results are mixed and instructive.
What worked in JAM-DEX
The technical infrastructure worked. JAM-DEX wallet transactions clear in under two seconds, with no transaction fee, on a settlement rail that is fundamentally cheaper than the card networks. The cryptographic settlement model has not had a meaningful security incident. The wallet UX is acceptable — comparable to what a typical mobile-money customer expects, though not best-in-class.
Government distribution worked. Social-program disbursements that previously required cash queues at post offices or bank branches now flow into JAM-DEX wallets digitally. Recipients can spend the funds directly from the wallet without converting to cash. This category of digital-currency rollout — government-to-citizen flows — is the part that JAM-DEX has measurably improved over the legacy cash-distribution rails.
Inclusion has improved modestly. The wallet sign-up flow does not require a traditional bank account, which has brought a meaningful share of the previously unbanked Jamaican population into a digital-payments rail. This is a structural improvement that the card networks alone could not provide.
What did not work
Merchant adoption has been the persistent gap. Four years in, the share of Jamaican merchants accepting JAM-DEX is roughly 14% — a fraction of the share that accept card payments (about 67%) or cash (essentially 100%). The merchant economics did not pencil. The incremental customer base from accepting JAM-DEX was small enough, and the operational cost of integrating a new payment rail was high enough, that most Caribbean merchants chose not to.
Consumer-to-consumer adoption was strong, but consumer-to-merchant adoption stalled. Customers used JAM-DEX wallets to send money to family and friends, to settle informal debts, to handle splits at restaurants where the bill payer was paying the restaurant by card. But the wallet-to-merchant flow stayed thin.
The currency-of-account problem is real. Merchants who accept JAM-DEX still receive funds denominated in JMD, but the wallet flow does not integrate cleanly with the merchant card-payment dashboards. Reconciling JAM-DEX takings against card takings against cash takings adds operational overhead for the merchant. Most chose to skip the third rail.
What the next wave of caribbean cbdc adoption needs to fix
Adoption beyond JAM-DEX — the Bahamas Sand Dollar pre-dated JAM-DEX, and at least three other Caribbean monetary authorities are now in active design phases — needs to address the merchant integration problem head-on. A few specific requirements have emerged from the JAM-DEX experience:
Direct integration with merchant terminals matters. CBDC payment acceptance should be a checkbox in the merchant payment processor dashboard, not a separate wallet app the merchant has to manage. Caribbean CBDC adoption only scales if the merchant integration is invisible.
Settlement consolidation matters. The CBDC takings, the card takings, and the cash takings should all flow into the same merchant operating account on the same reconciliation timeline. Three separate settlement streams is operationally unsustainable for a small merchant.
Customer-side incentives matter. Card networks pay rewards to consumers for using cards. Cash carries no such incentive but is widely accepted. CBDCs need some equivalent — either consumer-side rewards or merchant-side cost savings passed through to consumers — to break the chicken-and-egg of cold-start adoption.
Regional interoperability matters. A JAM-DEX wallet that cannot transact with a Sand Dollar wallet or with the equivalent CBDC in a neighboring island captures only the within-country use case. Caribbean CBDC adoption will accelerate when the wallets interoperate across the regional borders that customers and merchants already operate across.
What this means for Caribbean merchants
For the typical Caribbean merchant in 2026, caribbean cbdc adoption is still a secondary consideration. Card and cash remain the primary acceptance channels. Mobile-money fills the niches that CBDC theoretically would. The next two to three years will tell whether the next wave of caribbean cbdc adoption can solve the merchant-integration problem that JAM-DEX did not.
In the meantime, the right posture for a Caribbean merchant is to ensure that whichever processor they run on is designed to add a CBDC rail when the regional infrastructure makes it economically rational. A processor that is locked into card-only acceptance becomes a liability as soon as caribbean cbdc adoption hits the inflection point.

The longer arc
The JAM-DEX experience suggests that caribbean cbdc adoption is a 10-year arc, not a 3-year one. The infrastructure is being built. The first wave taught the region what works and what does not. The second wave will likely address the merchant integration problem. The third wave will probably address regional interoperability. By the end of the decade, caribbean cbdc adoption will be a meaningful share of regional payments. For now, it is the smallest share — but the most strategically interesting to watch.
