New Merchant Discount Rate (MDR) rules for select UPI transactions are set to take effect on October 15, 2026. While the broader framework introduces charges on Person-to-Merchant (P2M) transactions exceeding ₹2,000, specific provisions for capital market activities aim to limit the impact on retail investors.
Understanding the New UPI MDR Structure
Under the new guidelines, eligible P2M UPI transactions above ₹2,000 will generally incur a 0.4% MDR, capped at ₹300. However, capital market transactions, including mutual fund investments and stock purchases, have been placed in a distinct category, attracting a significantly lower MDR of 0.02%, also capped at ₹300 per transaction.
Crucially, the National Payments Corporation of India (NPCI) has clarified that applicable MDR will be borne by merchants and cannot be passed on as a separate UPI charge directly to consumers. Person-to-person (P2P) transfers and P2M transactions up to ₹2,000 will continue to have zero MDR.
Impact on Mutual Fund SIPs and One-Time Investments
For mutual fund investors, the distinction between recurring and one-time payments is vital:
- Mutual Fund SIPs via UPI AutoPay: Investments set up through UPI AutoPay or recurring mandates will not attract the prescribed MDR on the automated transaction. This means existing monthly SIPs linked to UPI AutoPay can continue without any additional charge.
- One-Time Mutual Fund Purchases: Eligible one-time mutual fund purchases made through UPI will fall under the 0.02% capital market MDR. For instance, a ₹5,000 investment would incur an MDR of ₹1, and a ₹10,000 transaction would imply ₹2, assuming the cost is passed on by the intermediary.
How Stock Investments Are Affected
Stock market investors using UPI for eligible payments will also see the 0.02% capital market MDR applied. A ₹50,000 stock purchase, for example, would result in an MDR of ₹10 at this rate, with larger transactions subject to the ₹300 cap.
Expert Opinions on Investor Impact
Brokerages and financial experts generally anticipate a limited direct impact on retail investors:
Jefferies suggests that the new framework is unlikely to materially alter the economics of retail investing through SIPs or stocks. Their analysis primarily focuses on the revenue opportunity for payment companies rather than forecasting a significant increase in investment costs for individual investors.
Dhiraj Relli, MD & CEO of HDFC Securities, highlighted the importance of the separate, lower rate for capital market transactions. "The decision to carve out capital market transactions into their own category at just 0.02%, capped at Rs. 300, is a considered decision to protect retail access to markets," Relli stated, suggesting the practical impact on stockbroking clients should remain minimal.
Concerns Raised by Brokers
While the direct cost to investors might be low, some industry figures have raised concerns specific to brokers. Zerodha founder Nithin Kamath pointed out that brokers could incur an MDR even if money transferred to a trading account does not result in an actual trade. Kamath suggested a lower cap, such as ₹5 or ₹10 per transaction, would be more reasonable for the broking industry than the ₹300 cap.
Key Takeaways for Investors
For investors, the critical point is that the new UPI MDR rules do not impose a blanket charge on all mutual fund SIPs or stock investments. Recurring investments through UPI AutoPay remain exempt from MDR. Eligible one-time capital market payments will incur a low 0.02% rate, with the ultimate cost to investors depending on whether intermediaries (brokers, mutual fund platforms, and AMCs) absorb this charge or pass it on.
