India's NPCI zeroed UPI fees to win small vendors
India's NPCI built UPI as a mandatory shared rail and set the merchant fee to zero, driving adoption among small vendors.

the move
Before 2016, moving money digitally in India meant navigating a fragmented landscape of separate bank apps, mobile wallets, and card networks that didn't talk to each other — a customer of one bank often couldn't pay a merchant or friend banking elsewhere without friction, delay, or fees. Card networks, the dominant model for digital merchant payments worldwide, charged merchants a Merchant Discount Rate on every transaction, which was enough to keep many small vendors — street stalls, tea shops, local vegetable sellers — from accepting digital payment at all.
The Reserve Bank of India and NPCI launched the Unified Payments Interface as a pilot on April 11, 2016, in Mumbai, with 21 member banks, built as an open protocol layered on top of the existing Immediate Payment Service infrastructure rather than as a separate competing network.
UPI's design forced interoperability by construction: it was built as a shared open standard that all participating banks connect to, so a payment from any bank's app reaches any other bank's customer using a simple virtual payment address instead of account numbers — commoditizing what card networks kept as a fee-generating layer between banks and merchants. Then, on the recommendation of the Nandan Nilekani committee on digital payments, the government mandated in January 2020 that the Merchant Discount Rate on UPI transactions be set to zero. That single choice removed the exact cost that h
why it works
- Zero fees removed the exact cost that kept small vendors off digital payment.
- Interoperability meant one QR code worked for every bank and customer.
- Universal zero-cost acceptance made adoption a rational default for vendors.
- Adoption itself created value that outweighed the forgone fee revenue.
what transfers
When adoption of a shared network is the goal, removing the per-transaction fee can drive scale that a fee-charging model never reaches.
what came after
UPI grew from 93,000 transactions in 2016 to over 250 billion a year by 2025, worth $3.4 trillion in transaction value. UPI became the world's largest real-time digital payment system by transaction volume, reportedly processing roughly half of all digital transactions globally by 2025, and its interoperable, zero-fee-rail model has been studied and partially exported to other countries building national instant-payment systems.
