Today, 130 countries are exploring a central bank digital currency (CBDC) — up from 35 in 2020, according to Atlantic Council’s CBDC Tracker. Using digital twins — replicas of a payment or settlement system — central banks can safely test the design, policies and potential wallet limits that could drive public adoption of CBDCs.
To test the effect of design options on retail CBDC adoption rates, network analytics firm FNA has used an agent-based model to build a digital twin of Spain’s retail payment ecosystem. Learning through simulation, CBDC stakeholders are able to iterate and test design options that support central bank aims, and prove attractive to consumers and merchants, ensuring the stability of the financial system.
