Model Answer

Merchant Discount Rate (MDR) is a fee paid by merchants to payment-system participants for processing digital transactions. From October 15, 2026, a 0.4% MDR will apply to specified UPI merchant payments above ₹2,000, while consumers and most small transactions remain exempt.

Why MDR has been introduced

1. Infrastructure costs rise with rapidly expanding transaction volumes. e.g: UPI processed 2,451 crore transactions in August 2026.
2. Financial sustainability is necessary for banks and payment providers maintaining UPI infrastructure.
3. Cybersecurity investment requires continuous spending as digital-payment fraud becomes sophisticated.
4. Service innovation needs sustainable incentives for payment applications and financial institutions.
5. System resilience requires investment in servers, fraud detection and customer support.
6. Reduced subsidy dependence can make the payment ecosystem financially sustainable over time.

Benefits and concerns

1. Small users remain protected as P2P payments continue to be free.
2. Small merchants remain protected under specified exemptions. e.g: Merchants receiving up to ₹1 lakh monthly through eligible UPI QR payments.
3. Everyday payments remain unaffected as merchant transactions up to ₹2,000 remain free.
4. Merchant costs may increase for businesses receiving larger-value payments.
5. Cost pass-through could indirectly affect consumers despite safeguards.
6. Digital adoption may slow if merchants encourage cash or alternative payment modes.

Way Forward

1. Periodically review MDR rates based on ecosystem costs and adoption.
2. Protect small merchants while preventing indirect charges on consumers.
3. Use ecosystem revenues to strengthen cybersecurity, grievance redressal and payment infrastructure.

UPI’s next phase requires balancing affordability with financial sustainability. A calibrated MDR framework can preserve inclusion while ensuring that India’s digital-payment infrastructure remains secure, innovative and resilient.
