Introduction
Under the new UPI merchant discount rate framework announced by the National Payments Corporation of India, transactions involving mutual funds, securities, stockbrokers and dealers will attract a substantially lower rate of 0.02 percent, capped at Rs 300, compared with the general 0.4 percent applying to other merchant payments above Rs 2,000. The framework takes effect from October 15, 2026.
Why Capital Markets Got a Lower Rate
The government has said the reduced rate is intended to keep the cost of digital investing low and encourage greater participation in formal financial markets. The reasoning is straightforward: investment transactions are typically high in value but low in margin for the intermediary, so applying the standard 0.4 percent rate would impose a disproportionate cost on a category of activity policymakers are actively trying to grow.
Rate Comparison
| Transaction Category | MDR | Cap |
|---|---|---|
| General P2M above Rs 2,000 | 0.4% | Rs 300 (for Rs 75,000+) |
| Mutual funds, securities, stockbrokers, dealers | 0.02% | Rs 300 |
| Essential services (railways, fuel, education, govt utilities) | Capped charge | Rs 5 above Rs 2,000 |
| P2M up to Rs 2,000 | Zero | - |
| P2P transfers | Zero | - |
What It Means in Practice
At 0.02 percent, a Rs 1 lakh mutual fund investment made via UPI would attract an MDR of Rs 20, versus Rs 400 under the general rate. For a Rs 10 lakh transaction, the Rs 300 cap kicks in, meaning the effective rate falls well below 0.02 percent on larger investments. Crucially, the MDR is collected on the merchant side, meaning investors themselves do not face a direct charge.
Who Bears the Cost
- The MDR is collected within the merchant side of the transaction, not from the consumer.
- It is distributed among the issuing bank, acquiring bank, payment service provider bank and UPI app.
- Payment aggregators are compensated from the acquiring side.
- NPCI has prohibited UPI apps from charging customers platform fees.
Implications for Brokers and Platforms
For brokerages and investment platforms that have built customer acquisition and transaction flows around zero-cost UPI, the introduction of any MDR represents a new line item, even at 0.02 percent. Platforms processing high volumes of small SIP transactions may find the impact minimal given most fall below the Rs 2,000 threshold entirely, while those handling larger lump-sum investments will see the Rs 300 cap limit their maximum per-transaction exposure.
Expert Insight
Payments and capital markets analysts note that the differentiated rate structure reflects a deliberate policy choice to avoid taxing financialisation, since India has spent years encouraging household savings to move from physical assets into mutual funds and equities. A 0.4 percent charge on investment flows would have worked directly against that objective, making the carve-out a logical if somewhat unusual feature of an MDR framework.
