Supreme Court declines to halt Oct. 15 UPI MDR rollout, seeks legal clarity

Signals to track

• Court hearing outcome in four weeks, especially findings on legal authority, constitutional basis and interim collection permission.
• Formal notification specifying MDR rate, caps, merchant-size exemptions, payer, recipient, tax treatment and effective enforcement date.
• NPCI, RBI, bank and PSP implementation circulars covering transaction routing, settlement, reconciliation and surcharge disclosure.
• Statements from merchant associations, large marketplaces and fuel, grocery, pharmacy and transit operators on pass-through or acceptance restrictions.
• Changes in UPI transaction mix, payment failures, merchant acceptance rates and migration to cards or cash after Oct. 15.
• Government signals of reimbursement, subsidy, tax relief or differentiated MDR for small merchants and priority sectors.
• Model blended payment acceptance costs by UPI share, ticket size, merchant category and acquiring contract; prioritize high-UPI, low-margin formats.
• Prepare checkout and POS capabilities for compliant fee disclosure, surcharge restrictions, payment-method steering rules and rapid rate-table updates.
• Renegotiate acquiring and PSP agreements for MDR pass-through mechanics, dispute liability, settlement timing, data reporting and volume-based rebates.
• Test targeted migration offers toward cards, wallets, bank transfer rails, store credit or cash for low-margin transactions without degrading conversion.
• Segment merchant network exposure: micro-merchants and franchisees may require temporary fee support, revised commissions or centralized acquiring arrangements.
• Establish a legal-and-policy response plan for alternative outcomes, including paused collection, retrospective adjustments and customer refunds.
