Central banks are increasingly pondering whether to issue their own digital currencies to the general public, so-called retail central bank digital currency (CBDC). The majority of IMF member countries are actively evaluating CBDCs, with only a few having issued CBDCs or undertaken extensive pilots or tests. This paper shines the spotlight on the handful of countries at the frontier in the hope of identifying and sharing insights, lessons, and open questions for the benefit of the many countries following in their footsteps. Clearly, what can be gleaned from these experiences does not necessarily apply elsewhere. The sample of countries remains small and country circumstances differ widely. However, the insights in this paper may inspire further investigation and allow countries to gain time by building on the experience of others. Importantly, the purpose of this paper is not to evaluate the courses taken by different jurisdictions, but to study and discuss their key experiences and lessons. The paper studies six advanced CBDC projects, drawing on collaboration and exchanges with the respective central banks to get insights beyond what has previously been published. Unless a specific published source is cited, all information stems from interviews and workshops with members of CBDC project teams in each jurisdiction.

Major transformations in payment and settlements have occurred in generations. The first generation was paper-based. Delivery times for payment instruments took several days domestically and weeks internationally. The second generation involved computerization with batch processing. Links between payment systems were made through manual or file-based interfaces. The change-over period between technologies was long and still some paper-based instruments like checks and cash remain in use. The third generation, which has been emerging, involves electronic and mobile payment schemes that enable integrated, immediate, and end-to-end payment and settlement transfers. For example, real-time gross settlement systems have been available in almost all countries. DLT has been viewed as a potential platform for the next generation of payment systems, enhancing the integration and the reconciliation of settlement accounts and their ledgers. So far, experiments with DLT experimentations point to the potential for financial infrastructures to move towards real-time settlement, flatter structures, continuous operations, and global reach. Testing in large-value payments and securities settlement systems have partly demonstrated the technical feasibility of DLT for this new environment. The projects examined analyzed issues associated with operational capacity, resiliency, liquidity savings, settlement finality, and privacy. DLT-based solutions can also facilitate delivery versus payment of securities, payment versus payment of foreign exchange transactions, and efficient cross-border payments.
