IMF video clip with BIS director on CBDCs (at 24:00), https://meetings.imf.org/en/2020/Annual/Schedule/2020/10/19/...

> With cash, we don't know who is using the 100 dollar bill today ... a key difference with CBDC is that the central bank will have absolute control on the rules and regulations that determine the expression of that central bank liability .. also we will have the technology to enforce that ... if an advanced economy issues a CBDC, and someone in a 3rd country wants to use it, it will require the consent of the central bank of the residence of that person, therefore the degree of control will be far bigger.
