The Securities and Exchange Board of India (SEBI) has announced that it will probe the new UPI merchant discount rate (MDR) framework that will take effect on 15 October. The revised structure, which adds an extra fee on large fund transfers, has raised questions among discount brokers about the cost implications for their clients. Discount brokers argue that the additional UPI charges will disproportionately burden them, as the fees are levied on every large transfer and are not covered by any insurance after the transaction is completed.
They also point to the complexity of quarterly settlement cycles, which could further inflate operational costs and reduce the margins available for retail traders. For everyday investors, the outcome of SEBI’s investigation could translate into higher brokerage fees and a dampening of trading activity. If the new MDR is upheld, the cost of executing large orders on the NSE could rise, potentially pulling some investors away from high‑volume trades that feed the Nifty and Sensex indices.
A reduction in trading volume might also affect liquidity and volatility in the market. Investors should keep an eye on SEBI’s final ruling, which could either confirm the new fee structure or mandate adjustments to protect market participants. Until then, brokers and retail traders may need to reassess their cost structures and consider alternative payment methods to mitigate the impact on their portfolios.
