In brief
- Two prototypes explored settlement with multiple central bank currencies.
- Access, jurisdiction and governance remained central design questions.
What the experiment established
On 22 March 2022, the BIS Innovation Hub and four central banks announced completed prototypes for Project Dunbar. Australia, Malaysia, Singapore and South Africa participated in the work. The experiment explored whether financial institutions could transact directly using several central bank digital currencies on one shared platform. The partners reported technical viability, with potential to reduce reliance on intermediaries.
Why revisit it
The difficult questions extended beyond software: which banks could participate, how national rules would apply, and who would govern shared infrastructure. For readers following international payments, Dunbar is a useful example of those competing requirements. Technical demonstrations alone do not establish a production service, universal access or measured savings for people sending money abroad. Those outcomes were not demonstrated by this announcement.
