The more important story is that India did not just build a popular payments product. It built a public digital rail that changed how consumers pay, how merchants accept money, and how financial services can be distributed at scale.

Launched in 2016, UPI was designed to connect multiple bank accounts through a single mobile application and enable peer to peer and merchant payments on a common infrastructure layer. That design choice mattered. UPI did not force the market into one closed wallet, one winning bank, or one dominant product architecture. It allowed banks, fintechs, merchants and consumers to participate on the same rail.

A decade later, the scale is difficult to ignore. In FY 2025 to 2026, UPI processed more than 24,162 crore transactions, with value exceeding ₹314 lakh crore. More than 700 banks are live on the system, and the Ministry of Finance says UPI accounts for nearly 49% of global real time payment transaction volume.

But scale is not the only reason UPI matters. The more interesting question is what kind of scale it created.

UPI did not begin by digitising large corporate payments. It digitised everyday life. Grocery stores, tea stalls, pharmacies, restaurants, cab drivers, freelancers and small merchants could accept digital payments without card machines or heavy acceptance infrastructure. Consumers did not need cards. Merchants did not need expensive hardware. Banks did not need to own the front end app to remain part of the transaction.

That is why UPI dominates payment volume but not payment value. According to RBI’s Payments System Report for December 2025, reported by Economic Times, UPI accounted for 85.5% of India’s payment transaction volume in the second half of 2025, but only 9.5% of transaction value. RTGS, by contrast, accounted for only 0.1% of transaction volume but 68.6% of transaction value.

This is not a weakness. It shows exactly where UPI sits in the payments stack.

UPI owns the high frequency, low value layer of the economy. RTGS continues to dominate large value transfers. Other systems continue to serve their own use cases. India’s payments architecture has not become a one rail market. It has become a layered system where UPI has changed the default behaviour for everyday payments.

The strategic lesson is that UPI solved for interoperability before monetisation. In many digital markets, companies first build closed ecosystems and then try to extract economics from users or merchants. UPI reversed that logic. It created the shared rail first. Competition then moved to the customer interface, reliability, rewards, merchant acquisition and adjacent financial products.

This has also created a new challenge. UPI is open infrastructure, but usage has concentrated around a few large apps. PhonePe and Google Pay remain the two largest UPI apps, with around 45% and 33% market share respectively, according to Moneycontrol’s April 2026 report.

That is not surprising. In platform markets, users cluster around interfaces they trust. Merchants prefer apps that customers already use. Scale reinforces itself. But it does create a strategic tension: how does an open public rail remain competitive when the consumer interface is concentrated?

The second challenge is monetisation. UPI has created enormous public value, but private value capture is less straightforward. Banks support the infrastructure. Fintech apps compete for users. Merchants benefit from low friction acceptance. Consumers receive convenience. The system works extremely well as infrastructure, but direct payment economics remain thin.

That is why the next decade of UPI will likely be less about payments alone and more about financial services around payments. Credit on UPI, merchant lending, working capital, subscriptions, insurance distribution, loyalty, identity linked services and cross border remittances may become more important than the payment transaction itself. The payment becomes the entry point. The economics come from what sits around it.

The third challenge is trust. As digital payments become part of daily economic life, fraud control, dispute resolution, cyber security and consumer education become core infrastructure issues. The government has pointed to safeguards including device binding, two factor authentication through PIN, daily transaction limits, restrictions on certain use cases, and NPCI’s AI and machine learning based fraud monitoring solution for banks.

This is where UPI’s second decade becomes more complex than its first. Adoption can be driven by convenience. Resilience requires governance, uptime, security and trust at national scale.

The final opportunity is global. UPI is now live in more than eight countries, including the UAE, Singapore, Bhutan, Nepal, Sri Lanka, France, Mauritius and Qatar. India has also signed agreements with 23 countries for cooperation on digital public infrastructure.

But global expansion should not be seen as simple replication. UPI worked in India because of a specific mix of banking access, mobile adoption, regulatory support, merchant density, consumer pain points and public infrastructure thinking. Other countries may want the outcome, but the operating model will need local adaptation.

That is why the real export is not just UPI as a payment product. It is the playbook: build interoperable rails, allow public and private actors to participate, reduce transaction friction, and let innovation happen on top of shared infrastructure.

UPI’s first decade proved that public digital infrastructure can change payment behaviour at national scale.

Its next decade will test whether India can convert payment scale into sustainable economics, safer rails, stronger financial services and global infrastructure influence.

The first phase was about adoption.

The next phase will be about value capture, resilience and trust.
