Summary


China leads by scale and ambition, with the e-CNY deeply embedded in domestic systems and actively pushing for cross-border utility.


India and Brazil are making steady but smaller strides in rollout and testing.


Japan is still in conceptual and pilot stages, motivated by domestic payment shifts.


Small economies like the Bahamas, Nigeria, and Jamaica have fully issued CBDCs, but adoption remains modest.


While China’s digital yuan stands out in breadth of deployment and strategic intent, it still faces hurdles in user acceptance, privacy perception, and global interoperability.
