UPI’s ₹16,000 crore MDR windfall could change the economics of digital payments

UPI processed ₹29.8 trillion worth of transaction in August, with merchant (person to merchant or P2M) payments accounting for roughly ₹9 trillion. Annualised, that is about ₹107 trillion of P2M value, of which roughly ₹72 trillion comes from transactions above ₹2,000. A 0.4% merchant discount rate (MDR) on transactions above ₹2,000 could theoretically generate nearly ₹28,000 crore. But after accounting for small-merchant exemptions, the ₹300 cap and concessional rates for categories such as fuel, telecom, insurance, railways and capital markets, industry estimates put the actual annual MDR pool closer to ₹16,000 crore.
