Imposing fees on large merchants for UPI payments risks undermining the digital payment revolution in India. The success of UPI has been its simplicity and zero cost to all stakeholders. Introducing charges, even to big merchants, could prompt them to pass costs onto consumers or discourage UPI usage altogether.
Merchants may respond by increasing prices or reverting to cash transactions to avoid fees, which would hurt India's broader digitalization goals. Smaller merchants, while currently exempt, could eventually face spillover effects if the overall UPI ecosystem becomes less attractive.
Additionally, fee implementation could create uncertainty and complexity in transactions, reducing the ease and trust that fueled UPI’s rapid growth. Policymakers risk complicating payment convenience, which could slow down financial inclusion and innovation.
Critics argue alternative models could be explored to fund infrastructure without charging merchants, such as government subsidies or tiered fees that consider business margins. Maintaining a cost-free or low-cost payments landscape remains critical for sustaining India’s digital economy momentum.
