UPI transaction volume growth has decelerated to 23.5% in the first four months of fiscal year 2027, down from 33.5% a year ago. The slowdown coincides with the passage of the Taxation and Other Laws (Amendment) Bill, 2026, which creates a framework for potential merchant fees. Government officials have clarified that UPI will remain free for regular consumers and person-to-person transfers.
The Unified Payments Interface (UPI) has witnessed a notable slowdown in transaction volume growth during the first four months of the current fiscal year. Data indicates that growth fell to 23.5% between April and July 2026, a decline from the 33.5% growth recorded during the same period in the previous year. This deceleration marks a shift from the rapid expansion seen in recent years and has sparked discussions regarding the financial sustainability of the digital payments ecosystem in India.
Legislative Changes and the Merchant Fee Debate
The slowdown in growth happens alongside active discussions regarding the Merchant Discount Rate (MDR). MDR is the fee that businesses pay to payment processors for handling digital transactions. To encourage the adoption of digital payments, this fee was waived for UPI transactions in 2020.
On August 6, 2026, the Lok Sabha passed the Taxation and Other Laws (Amendment) Bill, 2026. This legislation provides an enabling legal framework that allows for the potential introduction of MDR on certain electronic payment modes, including UPI. The legislative move aims to ensure the long-term financial health of the payment infrastructure, which has seen massive demand as UPI processes over 23 billion transactions monthly.
Impact on Fintechs and Market Expectations
For fintech companies and payment service providers, the current zero-fee model presents challenges. These firms have invested heavily in building and maintaining the infrastructure required to support billions of transactions. Industry players have frequently noted that the lack of a revenue stream from high-value transactions limits their ability to continue expanding their merchant networks and offering incentives. The current growth deceleration is viewed by some in the industry as a sign that the aggressive cashback and incentive-driven expansion model may be reaching its natural limits as companies shift their focus toward profitability.
Despite the legislative change, government authorities have emphasized that the consumer experience will remain unchanged. UPI transactions for regular users and person-to-person (P2P) transfers will continue to be free. If an MDR is introduced, it is expected to be nominal, threshold-based—potentially applying only to transactions above a certain value like ₹2,000—and restricted to a specific set of larger merchants. The actual rules, including the threshold limits and specific fee structures, will be decided by the NPCI-led UPI and Services Steering Committee.
For investors and market participants, the next critical update will be the specific guidelines released by the NPCI regarding the implementation of any fees. Tracking how the market adapts to potential merchant-side charges, without affecting the widespread consumer adoption that has made UPI a household name, will be key to understanding the future of the digital payments sector.
