India Built Payments as Public Infrastructure Instead of Letting Companies Own It
Rather than a card network taking a cut of every transaction, the rails were built as public infrastructure with near zero fees. The economic consequences of that choice are still unfolding.
The Design Choice
In most economies the payment layer is privately owned. Card networks and processors sit between buyers and sellers and take a percentage of each transaction, which funds the infrastructure and produces substantial profit.
India took a different approach, building the core layers as public infrastructure: a digital identity system, an interoperable real time payment system, and a framework for individuals to share their own financial data with providers they choose.
Why Interoperability Is the Key Feature
The payment system allows anyone to pay anyone across different banks and apps, instantly, with charges on person to person transfers set at effectively zero.
The consequence is that no single provider owns the network. A merchant accepting payment does not need a relationship with the payer bank or app, and a user switching apps keeps the same payment address. That removes the network effect that normally lets a payment provider entrench itself.
Making the rails open and free prevented anyone from owning them. The competition moved to services built on top rather than control of the pipe.
What It Enabled
| Layer | Effect |
|---|---|
| Digital identity | Account opening at very low cost |
| Instant payments | Cash displaced even for tiny amounts |
| Data sharing framework | Lending based on verified cash flow |
The identity layer matters more than it appears. Verifying who someone is had been a major cost of opening an account, which is why serving low income customers was uneconomic. Cheap verification changed that arithmetic.
The payments layer displaced cash for very small transactions, because zero fees make a payment of a few rupees viable where a percentage fee would not be.
The data layer is the one with the most potential remaining. A person with no credit history but a verifiable record of income and payments can be assessed on that record, which extends credit to people the traditional system could not evaluate.
The Costs of the Approach
Free is not free. Someone funds the infrastructure, and with no transaction revenue the funding comes from the state and from banks required to participate.
That creates a sustainability question. Banks bear costs for transactions generating no direct revenue, which weakens their incentive to invest in reliability and service. The counterargument is that they gain deposits and customer relationships, and whether that fully compensates is genuinely contested.
There is also a concentration risk. Public infrastructure everyone depends on is a single point of failure, and outages affect the entire economy rather than one provider customers.
The Surveillance Question
A system where the state operates identity and payment infrastructure creates capability that deserves scrutiny. Transaction records tied to verified identity are a comprehensive picture of economic activity.
Safeguards depend on legal limits and their enforcement rather than on technical impossibility, and the concerns raised about mandatory linkage of identity to services are legitimate rather than hypothetical. Any assessment of the model should treat this as a real cost rather than an afterthought.
Why Other Countries Are Watching
The interest elsewhere is mainly about the fee structure. Card interchange represents a meaningful cost on commerce, and a public alternative demonstrates that the function can be provided far more cheaply.
The difficulty in replicating it is that countries with entrenched card networks face incumbents with strong incentives to resist, and consumers attached to rewards programmes funded by the fees being targeted. Building this where nothing existed was easier than replacing something that works.
The Bottom Line
India treated identity and payments as infrastructure rather than as products, which drove transaction costs toward zero and prevented any company from owning the rails. It extended financial access substantially, it shifted rather than eliminated the cost of running the system, and it created state capability that requires real legal constraint to remain benign.
