Even as government considers MDR charge on UPI, data shows cash usage quickening in economy

The Hindu's recent analysis revealing a consistent deceleration in UPI transaction value growth since FY22, coupled with currency with the public growing at a faster pace, presents a fascinating paradox in India's digital payment journey. This trend emerges at a critical juncture when the government is contemplating reintroducing Merchant Discount Rate (MDR) on UPI transactions — a move that could fundamentally alter the economics of digital payments in India. To understand the significance, we must trace the historical trajectory. UPI, launched by NPCI in April 2016, revolutionized digital payments through its interoperable, real-time, mobile-first architecture. The game-changer came in January 2020 when the Finance Ministry, exercising powers under Section 10A of the Payment and Settlement Systems Act, 2007, mandated zero MDR for UPI and RuPay debit card transactions. This policy decision, aligned with the government's Digital India vision and the recommendations of the Ratan Watal Committee (2016) and Nandan Nilekani Committee (2019), aimed to accelerate digital adoption by removing cost barriers for merchants and consumers. The results were spectacular: UPI transaction volume surged from 1.3 billion in FY20 to over 84 billion in FY23, with value crossing ₹139 lakh crore. However, the current slowdown signals maturation challenges. The deceleration in value growth — despite volume expansion — suggests smaller ticket sizes per transaction, indicating UPI's penetration into low-value daily purchases (vegetable vendors, auto-rickshaws, kirana stores) where cash traditionally dominated. Simultaneously, currency with public growing faster (₹34 lakh crore as of March 2024 vs ₹28 lakh crore pre-demonetization) reflects persistent cash preference for high-value transactions, informal sector dealings, and as a store of value — a behavioral pattern documented by RBI's Currency and Finance reports. Key stakeholders face complex trade-offs. NPCI and payment service providers (PSPs) like PhonePe, Google Pay, Paytm bear infrastructure costs without direct revenue from UPI, creating sustainability concerns. Banks, mandated to maintain payment infrastructure under RBI's Payment and Settlement Systems Act, 2007, argue zero MDR disincentivizes investment. The Finance Ministry must balance fiscal prudence (MDR revenue potential) against political economy considerations — any merchant-facing charge could trigger resistance from small traders, a crucial electoral constituency. RBI's Payments Vision 2025 targets 3x digital payment volume growth by 2025, but this slowdown threatens that trajectory. Constitutionally, this intersects with Article 300A (property rights — merchants' right to conduct business without undue burden), Entry 45 of Union List (banking), and the broader Directive Principles under Article 38 (promoting welfare through financial inclusion). The MDR debate also touches on federalism — states have historically opposed central mandates affecting local trade. Economically, persistent cash usage undermines tax compliance (GST evasion), monetary policy transmission, and financial inclusion goals. The World Bank's Global Findex 2021 noted India's account ownership at 78%, but usage remains low. Socially, cash dependence excludes marginalized groups from formal credit histories. Internationally, India's UPI model — now exported to Singapore, UAE, France, Sri Lanka — faces credibility questions if domestic growth stalls. Future implications are profound. If MDR is reintroduced (likely tiered: zero for small merchants, charged for large), it could stabilize payment ecosystem economics but risk adoption slowdown. Alternatively, the government may explore alternative funding — transaction fees on high-value UPI, government subsidies for digital infrastructure, or monetizing data (with consent under DPDP Act, 2023). RBI may accelerate CBDC (e₹) pilots as a sovereign digital alternative. For aspirants, this encapsulates the tension between policy intent, market dynamics, and behavioral economics — a recurring theme in India's governance challenges.
