Starting October 15, 2026, a 0.4% Merchant Discount Rate (MDR) will apply to UPI transactions exceeding ₹2,000. This regulatory change aims to fund infrastructure and security costs, creating a new revenue stream for banks and payment aggregators. Investors may monitor how payment firms adjust their business models and handle increased competition for merchant volumes.
The Indian government has finalized a new regulatory framework for Unified Payments Interface (UPI) transactions, introducing a 0.4% Merchant Discount Rate (MDR) on payments exceeding ₹2,000. This change, which comes into effect on October 15, 2026, follows amendments to the Payment and Settlement Systems Act, 2007. The move marks a significant shift for the digital payments ecosystem, as these transactions had previously been free for merchants and consumers.
Under the new guidelines, transactions up to ₹2,000 and all person-to-person (P2P) transfers will continue to be free. However, for higher-value merchant payments, the 0.4% fee will be shared across the payment chain. High-value transactions of ₹75,000 and above will be subject to a flat cap of ₹300 per transaction. Specific sectors also have unique structures: essential services like railways, telecom, and fuel payments will incur a flat ₹5 fee, while capital market transactions, such as investments in mutual funds or stocks, are set at a 0.02% rate.
Impact on Payment Aggregators
For payment aggregators, this regulatory shift provides a structured revenue model. Analysts anticipate that these companies may retain approximately 9 to 10 basis points (bps) of the fee, while the remaining portion is allocated to banks to cover infrastructure and security investments. Previously, banks often faced challenges in justifying investments in UPI infrastructure due to limited cost recovery. The new policy is designed to address this by ensuring that all participants in the ecosystem receive compensation for their services.
This development is expected to heighten competition among payment aggregators. With a set fee structure in place, companies will likely focus on aggressive merchant onboarding to increase transaction volumes, as total revenue will now depend on the scale of payments processed. Aggregators that successfully secure large merchant networks may see a direct impact on their fee-based income, whereas those with smaller or less active merchant bases might find it harder to maintain margins.
Investor Monitorables
While the introduction of fees is a positive for the financial sustainability of digital payments, there are inherent risks. Merchants in low-margin segments may experience slight cost adjustments, which could lead to resistance or shifts in payment preferences. Additionally, the industry is entering a phase where the "free-for-all" model is ending, potentially triggering short-term volatility as companies adjust their pricing strategies to remain competitive.
Investors may watch for how individual payment companies and financial institutions report these revenue streams in their upcoming quarterly updates. The key to long-term profitability for these players will be their ability to manage operational costs while scaling their merchant base under the new fee-sharing framework.
