Digital public infrastructure and the next wave of fintech
Shared rails for identity, payments and data are changing who can build financial services — and who gets to use them.
· 1 min read
Several large emerging economies have taken a distinctive approach to digital finance: rather than leaving every layer to private companies, the state or a public-private body builds shared rails that anyone can plug into.
The three layers
Why it changes the competitive map
When onboarding and payments become cheap utilities, the competition shifts to what is built on top: credit, insurance, savings and business tools. Smaller players can compete with incumbents on product rather than distribution.
The risks
- Concentration — a single outage affects the whole economy.
- Privacy — data-sharing must be genuinely consent-based.
- Exclusion — people without devices or documents can be left further behind.
“Public rails, private innovation: the model works when governance is as carefully designed as the technology.”
