DPI Brief — September 28, 2026

The UPI merchant fee reaches the Supreme Court today (L2 — Payments). A bench led by Chief Justice of India Surya Kant, with Justices Joymalya Bagchi and V. Mohana, hears a PIL challenging the Centre’s 0.4% MDR on UPI person-to-merchant transactions above ₹2,000, seventeen days before the levy takes effect on October 15. The petition by advocate Anjan Datta attacks the September 14 notification and the September 15 framework on both process and design: no public consultation, no statutory safeguards, and an unexplained asymmetry — RuPay debit cards keep their “no charge” protection without any monetary ceiling while UPI above ₹2,000 gets levied. It asks the Court to require any future MDR classification to rest on evidence: merchant turnover, MSME status, actual margins, geography and ability to pay — not cliff-edge thresholds. The courtroom challenge lands amid widening street resistance: the All India Mobile Retailers Association has called a “No UPI Day” for October 2, petrol stations across Punjab plan to refuse UPI above ₹2,000 from October 16, and the Centre has ruled out a rollback even as it meets trader bodies. What no official has yet answered is the consumer question: with merchants free to pass the fee on, who actually ends up paying for “free” payments?

The rails get stress-tested while the fee is argued (L2 — Payments). As this brief publishes, bank unions have begun a three-day nationwide strike (September 28–30) pressing for a five-day week, hitting public-sector banks and regional rural banks; several banks kept counters open through Sunday so customers could clear work before September 30 half-yearly closing. The telling part for DPI watchers: UPI, ATMs and mobile banking are expected to keep running through the strike — branch banking is now the fragile layer, the digital rails the resilient one. That resilience has numbers behind it: an IMF assessment names UPI the world’s largest retail fast-payment system by transaction volume, and NPCI data put August at about 24.5 billion transactions worth ₹29.82 lakh crore — roughly 790 million payments a day — up from 17.8 million transactions in all of FY2016-17.

Subsidised LPG goes biometric from Thursday (L1 — Identity). From October 1, domestic LPG consumers must complete Biometric Aadhaar Authentication to keep receiving subsidy on refills; the unverified can still buy cylinders, but at full market price. The Petroleum Ministry reports 27.43 crore consumers — 89.9% of the active base — already authenticated, leaving roughly 3 crore to convert within days. The Hindu’s explainer walks through the options — fingerprint, iris or face — and what breaks without them. The worry is the record: as The Wire chronicles, successive governments insisted Aadhaar was not compulsory for LPG, and the requirement keeps returning by another door. De-duplication is a legitimate goal; the test is whether the ~10% who miss the deadline face friction rather than forfeiture of a cooking-fuel subsidy. Same identity window: free biometric updates for children’s Baal Aadhaar close on September 30, after which the fee applies.

AgriStack reaches scale in Gujarat as the Rabi dialogue opens (L5 — Sectoral). Gujarat’s Farmer Registry has crossed 63.35 lakh farmers, each record linking Aadhaar-based identity to verified land holdings — exactly the verified farmer-state dataset that AgriStack’s credit, insurance and procurement use-cases presuppose. Today and tomorrow, the National Conference on Agriculture for Rabi Campaign 2026 meets in Delhi with digital agriculture on the agenda; worth watching is whether other states publish registry coverage at Gujarat’s granularity. The consumer stake: a registry that verifies entitlements is a benefit; one that silently gates them is a single point of failure.

TRAI rewires prepaid recharge rules toward the buyer (L7 — Trust). The Telecom Consumers Protection (13th Amendment) Regulations, 2026 — notified September 22 — require operators to offer voice-and-SMS-only special tariff vouchers for every bundled validity of 30 days or less, at appropriately reduced tariffs, alongside a same-date monthly renewal voucher and true 30-day plans — twelve recharges a year instead of thirteen on the 28-day cycle. The rules followed a consultation that drew 1,132 responses, and the push gained force after parliamentarians flagged how the 28-day cycle quietly extracts an extra recharge each year. Plan design sounds minor; for prepaid-majority India it is the price of the network itself, and the trust layer just tilted it back toward the consumer.

CPGRAMS publishes its August scorecard (L6 — Governance). DARPG’s 52nd monthly CPGRAMS report counts 2,51,147 grievances received in August, average disposal time down to 13 days in 2026, and 1,38,801 new registrations — West Bengal (42,054), Uttar Pradesh (17,202) and Maharashtra (10,616) lead — with Common Service Centres now feeding the portal. The fine print deserves skepticism: a backlog of 93,864 cases persists, and “disposal” is not the same as “resolution” — 44% of grievances target the heavy-lift ministries (Rural Development, Labour and Employment, Financial Services) where closure quality is hardest to verify. Speed is improving; whether complaints actually get fixed remains a matter of trust.

Week ahead: Baal Aadhaar free-update deadline and half-yearly bank closing — September 30; LPG biometric authentication and other rule changes — October 1; AIMRA “No UPI Day” — October 2; UPI MDR switch — October 15; DPDP Consent Manager registration window — November 2026.
