Whereas first-generation digital currencies deployed by consortia of trade gamers might solely ship incremental modifications such because the discount in cash motion costs and decreasing the price of capital for unbanked, adoption throughout nations by way of CDBC 2.zero holds the potential to unlock vital worth out there for first-movers to seize.

In our latest work, we’ve got analyzed key notable tasks and developments round Digital Currencies, distilling them into key Digital Forex archetypes, see exhibit 1.  

Exhibit 1: archetypes and design concerns of digital currencies (Credit score: BCG)

All through our evaluation, we’ve got developed and utilized the Complete Social Affect framework (see exhibit 2) to know the societal worth chain influence of the introduction of digital currencies in addition to potential results of adoption by nations, central banks, companies, and particular person customers. Particular underlying drivers have been outlined and evaluated for every TSI dimension.
