Currency in Circulation Reaches Record ₹42.7 Trillion as Proposed 0.4% UPI Fee Stirs Merchant Shift to Cash

India’s flagship digital payments network is facing an unexpected friction point as retail merchants resist new transaction levies, prompting an uptick in cash reliance across trade hubs. The debate centres on a framework to introduce a 0.4% Merchant Discount Rate (MDR)—capped at ₹300 per transaction—on person-to-merchant (P2M) Unified Payments Interface (UPI) payments exceeding ₹2,000.

Although the levy is designed to support the escalating maintenance and infrastructure expenses of the ecosystem, retail shopkeepers operating on wafer-thin margins are pushing back. Many are displaying "cash only" notices or actively splitting customer bills to avoid breaching the ₹2,000 ceiling.

Merchant Resistance and the Zero-MDR Dilemma

Since its rollout in 2016, UPI has transformed Indian commerce, processing roughly 242 billion transactions over the latest financial year. However, the zero-cost architecture that drove widespread adoption has become an expensive burden for payment infrastructure operators.

According to operator data, the National Payments Corporation of India (NPCI)—collectively owned by retail banks—incurs approximately ₹200 billion ($2.1 billion) in annual network maintenance costs. Government budgetary subsidies, which stood at ₹20 billion for the current fiscal cycle, bridge only a fraction of that expenditure.

While policymakers emphasized that consumer transfers (person-to-person) and ticket sizes below ₹2,000 remain entirely fee-free, shopkeepers argue they cannot absorb transaction cuts:

• A national survey of 32,000 businesses conducted by LocalCircles revealed that 83% of merchants are unwilling to bear the proposed MDR costs.
• Regulated retailers, such as pharmacies selling medicines under capped Maximum Retail Prices (MRP), cannot mark up products to offset transaction fees.
• In essential and regulated segments such as railways, fuel, telecom, insurance, and agricultural inputs, a flat fee of ₹5 per transaction above ₹2,000 has been earmarked to minimize price disruption.

Following significant pushback from merchant associations, authorities postponed the initial mid-October rollout until after the festive season to avoid disrupting peak retail demand.

Cash Defies the Digital Boom

The pushback arrives at a time when physical currency holdings in India remain extraordinarily resilient. Despite eight years of digital payments expansion following the 2016 banknote withdrawal, data released by the Reserve Bank of India (RBI) shows currency in circulation reached a record high of ₹42.7 trillion ($448 billion) at the end of September 2026.

Key macroeconomic trends underscore the persistence of physical money:

• Currency in circulation is now roughly 2.3 times higher than pre-demonetisation levels.
• India's cash-to-GDP ratio has hovered back near 12%, returning to levels seen a decade ago and ranking among the highest of major emerging economies.
• RBI data indicates that even as UPI handles high-frequency daily retail volume, cash usage continues to expand at double-digit annual rates, fueled by the informal economy, festive demand, and agricultural trade.

Economists and former policymakers have expressed caution regarding the timing of the fee. Former NITI Aayog Vice-Chairman Rajiv Kumar warned that while transactions under ₹2,000 account for 96% of UPI transaction volume, higher-value transactions represent approximately 66% of the system's monetary value. Imposing MDR on this segment risks driving high-ticket retail settlement back into unrecorded cash transactions.

Market and Sector Impact

For Indian equity investors and financial sector participants, the fee debate creates mixed crosscurrents:

Fintech and Payment Aggregators: Listed digital payment companies and merchant acquirers have operated under unprofitable transaction models for years. Analysts estimate that a structured MDR on high-value retail payments could inject up to $1 billion in annual ecosystem revenues, aiding monetization for payment service providers if adoption remains intact.

Banking Infrastructure: Sponsoring banks stand to recoup server, anti-fraud, and clearing expenses that currently run at substantial losses. However, if merchant pushback results in bill-splitting or cash conversion, transaction ticket sizes may fragment, raising processing volumes without matching revenue gains.

Tax Transparency and Retail Margins: Small traders cite rising scrutiny from tax authorities alongside transaction fees as catalysts to return to paper currency. As retail chains balance consumer convenience against operating margins, the transition from government-subsidized digital rails to self-sustaining commercial rails remains one of the defining tests for India's digital public infrastructure.
