The Supreme Court’s decision not to grant an interim stay on the proposed 0.4 per cent Merchant Discount Rate on specified UPI merchant transactions above Rs 2,000 keeps the issue open for closer judicial scrutiny. While the court has sought responses from the Centre, RBI and other authorities, the larger question is whether a payment system that has become central to everyday commerce should now carry an additional transaction cost for certain users. The government’s position that ordinary UPI users will not be directly charged needs to be weighed against the impact on merchants, especially small businesses, who may ultimately have to absorb or pass on the cost.
UPI’s success has been built on simplicity, speed and low-cost digital payments. Introducing a charge on higher-value merchant transactions could alter that equation, even if the levy is limited in scope. For large businesses, the additional cost may be manageable, but for smaller merchants operating on thin margins, every transaction-related expense matters. At the same time, the sustainability of the UPI ecosystem cannot be ignored, and the payment infrastructure, banks and technology providers involved in processing these transactions also require viable economic models. The challenge, therefore, is to strike a balance between sustaining the digital payments infrastructure and preserving the affordability that helped UPI become a mass platform.
The Supreme Court’s intervention provides an opportunity to examine the issue beyond the immediate question of whether the levy should be stayed. The authorities need to explain clearly why the charge is necessary, how it will be collected and who will ultimately bear its economic burden. Transparency will be particularly important to prevent the cost from being quietly transferred to consumers through higher prices or other charges. As the court considers the legal challenge, the policy debate should remain focused on protecting the gains of digital payments while ensuring that the economics of the system do not undermine the very convenience and accessibility that made UPI a national success.
