UPI’s First Decade Is Over. The Next Challenge Is Making India’s Digital Payments Future Sustainable
Decades ago, settling your bills at the neighbourhood shop might have involved looking for some cash, waiting for change, or swiping a debit card. Today, all you need is a QR code and some tapping to do the same in seconds. While the Unified Payment Interface (UPI) was once a novel payment rail, it has evolved into much more: a ubiquitous digital infrastructure.
The UPI system was launched in April 2016 by the National Payments Corporation of India with oversight from the Reserve Bank of India in 21 banks. By March 2026, there were more than 700 banks live on UPI. In FY2025-26, UPI had processed over 24,161 crore transactions worth ₹314 lakh crore, almost 12,000 times the number of transactions that occurred in its first year.
But numbers alone only reveal the scope of the revolution. Numbers cannot capture the real success behind the phenomenon.
Today, with UPI entering its second decade, the challenge for India is not how it made digital payments mainstream. For that, the country has already done an exemplary job. The challenge is how India now makes its colossal digital payments ecosystem more sustainable, secure, inclusive, and internationally relevant.
How UPI Won the Everyday Payments Battle
UPI worked effectively since it offered an answer to a rather trivial question in an unexpectedly straightforward manner. In lieu of creating two separate payment systems for consumers and merchants, it introduced an additional layer that made bank accounts interoperable through the same interface.
As a result, a customer was able to transfer money straight from the bank account via a mobile phone, whereas a merchant could receive payments using QR code without installing any complicated card network.
It proved to be important since digital payments were no longer used exclusively by large businesses and urban consumers. They penetrated the world of kirana stores, food places, taxis, street vendors, utility payments and all other sorts of small payments which required cash until then.
Such scale of use is an illustration of this transition. According to government statistics, UPI made up around 85% of the digital transactions in India in the fiscal year of 2025-26. The number of users of this system was equal to 55.49 crore in June 2026.
Thus, UPI not only introduced digitalization of payments but normalized the concept of completing even a small transaction digitally.
The Secret Was Not Just Technology
UPI’s success could easily be described as that of technology. It is also the story of public infrastructure and policy coordination.
Banks, RBI, NPCI, fintech, mobile applications, and merchants all came together in an ecosystem. The government was able to boost its growth through its policies, while its bank to bank network meant that people would not have to change bank accounts to use it.
This resulted in a positive feedback loop. The more users there were, the more merchants used it. The more merchants used it, the more consumers got value out of using it. And more use of it would mean that banks and tech firms developed more products on top of the platform.
One way in which UPI differs from the traditional private payment system is in that regard. While customers may be using the app itself, the payment network goes beyond it.
From Payment Method to Economic Infrastructure
Perhaps the most significant change is happening under the surface of the transactions themselves.
UPI is gradually turning into an indispensable element of the way India’s formal and informal economy operates. A payment made to a vegetable vendor, a restaurant, a delivery boy or a small business creates a transaction record through which digital money trails while cash leaves hardly any traces.
These have consequences for financial inclusion, formalization of merchants and their access to financial products. Digital payments could become an instrument that facilitates the creation of transaction records and, possibly, even a financial history.
UPI has opened a new high-frequency channel for economic activity. Transactions are ongoing all the time in millions of consumers’ and merchants’ hands, so the payment data become a valuable source of information about shifting patterns of consumption and business.
None of this suggests that UPI should supplant traditional economic indicators. It does, however, suggest that the payment system has become an economic entity in itself.
The Global Story Has Already Started
UPI’s next chapter is not limited to India.
The system has increasingly attracted international attention because it offers an example of how a country can build interoperable digital payment infrastructure at population scale. Government data says UPI accounted for roughly 49% of global real-time payment transaction volume in 2025.
Its international expansion also creates an opportunity for India to influence how cross-border retail payments develop.
The ambition should not simply be to export an Indian payment app. The larger opportunity is to create interoperable payment connections that make it easier for Indian travellers, businesses and diaspora communities to transact internationally.
If domestic payments can be completed almost instantly, the next expectation will naturally be that international payments should become faster, cheaper and simpler too.
But Success Has Created a New Problem
UPI’s greatest hurdle might well be what made it so successful in the first place – size.
Any system that handles billions of transactions each month needs to be economically viable. As UPI has assumed the role of being at the core of India’s economy, the cost of keeping up and improving the infrastructure has risen accordingly.
That point has become extremely important this month, when the parliamentary standing committee pointed out a cost of operation of around ₹20,700 crore versus a government funding of ₹2,000 crore, and suggested a move towards a sustainable business model.
This is because one of the key advantages of UPI has always been its affordability. The Indian government recently reaffirmed that it wants to keep UPI free of charge for customers, while leaving open the possibility of introducing some merchant discount rate for higher transaction values.
India needs to walk a tightrope here: It cannot afford to compromise on UPI’s affordability, but also cannot assume that an infrastructure that supports hundreds of millions of people can grow indefinitely without a viable business model.
Security Will Become More Important Than Speed
While the core appeal of UPI for the first decade of its existence would be convenience, for the next decade it may turn out to be just as important as trustworthiness.
With the increase in the number of transactions, there is an increased risk of abuse from the criminals. This includes phishing, social engineering, fake payment instructions, account compromise and various AI scams targeting those individuals who might not know how to tell apart legitimate from fraudulent transactions.
Trust and security, however, should develop in tandem with convenience.
The future UPI experience should make it easier to spot fraudulent transactions while not making legitimate payments too cumbersome. Risk-based verification, advanced fraud protection and improved customer education will become key.
A payment platform can succeed only if its customers trust it to be both fast and reliable in case something goes wrong.
The Next UPI Should Be More Than a Payment Button
The next ten years of UPI would be about extending its capabilities through expansion.
RPA, credit facilities, international transfers, digital ID systems, account aggregation, and other financial services would form a wider network supported by interoperable rails.
However, it should be done without compromising the simplicity. The reason why UPI succeeded was due to the fact that it could be used without understanding its technological background. The future should see innovations that will keep this quality intact.
The user should not understand anything about API, payment rail, and authentication systems. All they should know is that the system works.

Inclusion Must Remain at the Centre
It is also dangerous to assume that digital adoption necessarily means inclusiveness.
In India, there are still those who encounter difficulties with smartphones, network availability, languages, digital illiteracy, disabilities, and lack of access to formal banking.
The next stage of the UPI system has to be more inclusive, including better support of regional languages, voice interface and limited network availability.
This does not mean just increasing transactions; this means making digital payments work for people who have previously been out of reach of formal finance.
What Comes Next
UPI’s first ten years have been all about establishing itself as an exemplary Indian digital payments system.
The next ten years will be about maturing the same.
Which means developing a sustainable economic model while keeping things affordable, making the system secure but not frictional, expanding the network globally without losing its interoperability, and using the system infrastructure to further financial inclusion, not merely growing the number of transactions.
Yet another sign that the system has progressed far came in July 2026 when UPI made new record in terms of number of transactions per month – 23.66 billion with total value of ₹29.88 lakh crore.
These numbers are indeed commendable. What would be the true test of UPI’s progress, however, is how the system continues to perform after reaching these unimaginably huge figures.
India has already built one of the world’s most important digital payment systems. The task now is to make sure that it can sustain its durability, security and inclusiveness for the next 100 million users and the next decade of India’s digital economy.
UPI revolutionized the Indian payments system.
Its future could define India’s presence in the global digital finance system.
