India Prepares Revenue Model for Its Dominant Payments Network

A Policy Turning Point

India's legislature has passed a bill that creates the legal infrastructure for merchants to pay transaction fees on the country's Unified Payments Interface, the government-built rails that now carry more than 23 billion payments each month. The move ends a policy that has kept merchant acceptance entirely free since early 2020, when authorities eliminated fees to drive adoption of the digital system.

The legislation itself does not mandate specific charges or define which transactions would incur costs. Instead, it establishes the regulatory architecture that would allow such fees to be introduced later through executive action. That approach gives policymakers flexibility to calibrate fee structures while the market adjusts to the shift.

UPI processed 23.66 billion transactions in July, moving 29.88 trillion rupees, figures from the National Payments Corporation of India show. Those volumes have made the network a cornerstone of India's retail economy, but they have also sharpened a years-long debate over how to fund the infrastructure, operations, and security investments required to maintain and expand the system.

The Economics Behind Free Payments

When India scrapped merchant discount rates in January 2020, the decision was rooted in a calculation that widespread adoption mattered more than immediate revenue. The government relied on direct subsidies and incentive programs to cover costs borne by banks and payment platforms, betting that ubiquity would unlock broader economic gains.

That wager succeeded in driving penetration. UPI is now accepted at street vendors, chain retailers, and nearly every point of sale in urban India. But as transaction counts have climbed into the tens of billions monthly, banks and fintech operators have argued that the zero-fee model has become economically unsustainable. Infrastructure upgrades, fraud detection systems, and server capacity all require capital, and the subsidy framework has not kept pace with the network's scale.

At DailyTechWire, we have tracked similar tensions in other markets where government-backed payment systems attempt to balance public-good objectives with private-sector sustainability. The Indian case is distinctive because UPI was designed from the outset as open infrastructure, with multiple competing apps riding the same interoperable rails.

Who Pays, and How Much

The legislation leaves critical design questions unanswered. Market analysts expect that any fee regime will target higher-value transactions rather than applying uniform charges across all payment types. Jefferies, an investment bank, published estimates suggesting that fees of 15 to 30 basis points on larger transactions could generate between 50 billion and 100 billion rupees in annual revenue by fiscal year 2028, roughly 525 million to 1.05 billion dollars.

Bernstein, another brokerage, noted in a recent report that transactions above 2,000 rupees account for only about four percent of payment volumes but nearly 70 percent of transaction value. A tiered structure that exempts small merchants and low-value payments would preserve the consumer-facing simplicity that has made UPI popular while creating a revenue pool large enough to fund network expansion.

Indian officials have signaled in recent weeks that any merchant charges would likely be confined to larger businesses, according to local reporting. That approach mirrors strategies in other markets where regulators have sought to avoid burdening micro-enterprises with transaction costs that could push them back toward cash.

Industry Response and Incentives

Executives at fintech companies and payment processors have welcomed the legislative shift. Amrish Rau, who leads Pine Labs, a prominent fintech firm, wrote publicly that the ability to recover a portion of infrastructure costs from merchants would enable continued investment in technology, innovation, and cybersecurity. Rau framed the policy change as essential to achieving deeper penetration and supporting UPI's international rollout.

The network is already live in Singapore, the United Arab Emirates, and France, and Indian authorities have positioned its global expansion as both a commercial opportunity and a diplomatic tool. A sustainable funding model at home would make the case for adoption abroad more credible, particularly in markets where governments are wary of relying on payment infrastructure that depends on indefinite subsidies.

Competitive Dynamics and Revenue Distribution

Two platforms dominate UPI transaction volumes. PhonePe, owned by Walmart, and Google Pay together handle nearly 80 percent of payments on the network, data from NPCI shows. How any merchant fee regime distributes revenue among issuing banks, payment apps, and network operators will determine whether those market leaders capture meaningful new income or simply pass fees through the system.

The competitive structure of UPI is unusual. Unlike closed-loop systems where a single company controls the network and reaps associated revenue, UPI is an open standard. Multiple apps compete on user experience and merchant relationships, but the underlying infrastructure is shared. That design has fostered innovation and prevented monopoly, but it also complicates revenue-sharing arrangements.

Banks have long argued that they shoulder the bulk of compliance and settlement costs while app operators capture user relationships and data. Any fee framework will need to address those tensions if it is to secure buy-in from all participants. The legislation gives regulators room to negotiate those allocations without locking them into statute.

Regional and Global Implications

India's decision to introduce a revenue model for UPI carries implications beyond its borders. Countries that have adopted or are considering similar instant-payment systems will watch closely to see whether merchant fees slow transaction growth or simply shift the cost burden without dampening usage.

The move also tests a broader thesis about digital public infrastructure. Advocates of government-built payment systems argue that they can deliver inclusion and interoperability more effectively than private networks. Critics counter that such systems struggle with sustainability once subsidies run out. India's experience over the next two years will provide evidence for both sides of that debate.

For now, the legislation is a signal rather than a final blueprint. Regulators must still design fee schedules, decide which transactions to exempt, and negotiate revenue splits among ecosystem participants. The details of those decisions will determine whether UPI enters a new phase of financial stability or faces fresh tensions between public mission and private incentive.
