HDFC Securities has announced that 98% of its digital transactions will be safe from the new UPI Merchant Discount Rate (MDR). MDR is a fee that banks and payment service providers charge merchants for processing digital payments. While many discount brokers are worried about these new costs, HDFC Securities says its unique payment mix protects it and its customers from price hikes.

From October 15, a new rule will apply a 0.02% charge on UPI transactions for capital markets. This includes money sent to stockbrokers and mutual funds. The fee is capped at ₹300 per transaction. This is lower than the usual 0.4% MDR for other shop payments above ₹2,000, but it still adds a new expense for the broking industry which previously enjoyed free UPI transfers.

Data from HDFC Securities shows they processed over 5.23 crore (52.3 million) transactions between January and August. Out of these, a massive 5.14 crore transactions happened through HDFC Bank-linked '3-in-1' accounts or net banking. Because these methods are not UPI-based, they do not fall under the new MDR rules. Only about 9.6 lakh transactions, or less than 2%, were done via UPI.

The '3-in-1' mandate is a special account that links a savings bank account, a demat account (where shares are kept), and a trading account. Because HDFC Securities is part of a large banking group, most of its clients already use this linked system for ease and speed. This internal banking route is now proving to be a big financial advantage.

This situation is very different for 'discount brokers' like Zerodha or Groww. In the wider broking industry, about 90% of transactions happen through UPI. Broker associations have told SEBI (the market regulator) that UPI accounts for two-thirds of all money added to trading accounts. These brokers are worried because they might have to pay the MDR fee even if a customer adds money but does not actually buy any stocks.

Dhiraj Relli, the MD and CEO of HDFC Securities, said that their customers prefer reliable channels that have naturally insulated them from this change. Since the cost impact is so low for them, the company does not plan to change its pricing for customers. This gives them a competitive edge over smaller brokers who may have to pass the costs down to the retail investor.

For bank officers, this story highlights the importance of 'bancassurance' and integrated banking models. When a broker is tied to a parent bank, they can move money through internal systems rather than relying on external payment apps. This keeps costs low and keeps the customer within the bank's own ecosystem.

SEBI has noted the concerns of the broking industry. The regulator mentioned it will examine these complaints to see if there are ways to ease the burden. For now, bankers and investors should watch if other bank-backed brokerages see similar benefits or if the industry pushes for a complete waiver of the UPI fee for security market trades.
