India moves to charge merchants fees on UPI, ending free-payments era

India is preparing to let banks and payment firms charge merchants a fee on UPI transactions, a shift that could close a decade-long run of free digital payments. Under proposals being weighed, a merchant discount rate of roughly 0.3–0.5% would apply only to larger transactions at big businesses—one option targets payments above 2,000 rupees—while consumer and person-to-person transfers stay free. Regulators frame the change as overdue: running servers, settling transactions, detecting fraud, and defending against cyberattacks all cost money the government has largely subsidized, and RBI governor Sanjay Malhotra bluntly notes that someone has to cover it.

UPI is enormous—23.6 billion transactions worth about $313.5bn in July alone, over 550 million users, and reach into 11 countries—built on shared public ‘plumbing’ run by a non-profit, with apps like PhonePe and Google Pay competing on top. The narrow fee design is deliberate: high-value payments are only ~4% of merchant volume but ~67% of value, so a targeted MDR could yield up to a billion dollars in new revenue without touching the neighborhood grocer. Brazil’s Pix, free for individuals but charging businesses modestly, shows such a model can coexist with rapid growth.

The risk sits in the design details. Research by economist Abhinav Motheram argues that merchant acceptance was a driver of UPI adoption, not just a byproduct, and warns that even a small fee could shift incentives for informal merchants on thin margins if charges eventually reach them—particularly in districts where acceptance networks are still thin. Network effects likely protect UPI from mass abandonment, but a 2024 survey found 75% of users say they’d quit if charged. The real test is whether pricing can fund the system while still protecting the marginal merchants being pulled into digital payments.
