The important thing about a UPI payment is what the customer does not have to coordinate: which bank the recipient uses, which participating app they prefer, or whether a branch is open. The network supplies a common route between accounts. Competing services can meet on the same payment infrastructure. [1] [2]
Launched in 2016, the Unified Payments Interface became one of the most consequential pieces of India’s digital infrastructure during the Modi years. Its success also has a longer institutional history than a launch ceremony can convey.
Built on institutions already in place
NPCI developed UPI on the earlier Immediate Payment Service infrastructure. RBI had helped establish NPCI in 2008 with ten core promoter banks. Banks, the regulator and the network operator therefore brought existing systems and responsibilities to the new interface. [1] [2]
The pilot began in April 2016 with 21 member banks. Public availability followed in August as participating banks released their applications; the BHIM app arrived in December. UPI and BHIM are consequently different things: the former is the shared payment system, the latter an application using it. [4]
This distinction explains why adoption could extend beyond a single government-backed app. Banks and other participating providers could develop their own customer interfaces while using the common network. RBI’s account of digitalisation describes the role of third-party applications working with payment service providers to connect users to UPI. [3]
A change in everyday payment infrastructure
By 2023–24, UPI accounted for 79.6% of the volume of retail payments in RBI’s comparison. A separate Finance Ministry review recorded more than 15,547 crore BHIM-UPI transactions between January and November 2024. These are dated measures of use, rather than forecasts about what the system might eventually achieve. [3] [5]
The units require care. Transaction volume counts payments, including repeated use by the same person. It cannot be read as a count of unique users. The value moving through a payment system is also not an addition to national income: money can pass between accounts repeatedly without representing newly produced goods or services.
Government backing belongs in this history, alongside NPCI’s engineering, RBI’s oversight, banks’ integration and the applications and merchants that made the network usable. Assigning the entire system to one politician would erase much of the work that explains its growth.
Reliability remains part of the same story. At the 2018 launch of UPI 2.0, RBI Governor Urjit Patel emphasised the need to protect the network’s security as it expanded. A payment interface earns its place in daily life each time the transfer works, the recipient can identify it and a problem can be resolved. Scale makes those ordinary requirements more demanding. [2]
