1) Payment efficiency and competition
Faster, cheaper payments; instant, programmable disbursements; and lower-cost cross-border settlement.

2) Financial inclusion
A public digital option can widen access where private fees or fragmentation exclude users, provided the design and UX are strong.

3) Monetary sovereignty and innovation

4) Policy and crisis tools
Potential for sharper monetary and fiscal transmission, depending on design choices.
