Investors using UPI for mutual fund SIPs or stock-market-related payments need to understand a new MDR-related cost highlighted in the supplied report. According to the report, a Merchant Discount Rate (MDR) of 0.02% has been introduced for payments linked to mutual funds and stock purchases.

The important point for investors is that the charge is described as being payable by the brokerage firm or Asset Management Company (AMC), rather than being directly deducted from the customer's UPI payment as a separate MDR charge.

However, experts cited in the report believe that financial intermediaries could eventually pass some of the additional cost on to customers indirectly.

So, while an investor may not immediately see a separate MDR line item while making a UPI payment, the broader cost structure of investment services could potentially be affected.

What Is the New 0.02% MDR Rule?

MDR, or Merchant Discount Rate, is a charge associated with processing certain digital payments.

According to the supplied information, the applicable MDR for UPI payments involving mutual fund investments and stock purchases has been set at 0.02%.

This means the charge works out to ₹2 for every ₹10,000 of transaction value.

For example:

These figures simply illustrate the mathematical impact of a 0.02% rate.

Who Is Supposed to Pay the MDR?

This is the most important part of the rule for retail investors.

According to the supplied report, the MDR liability falls on the brokerage firm or AMC handling the transaction.

Therefore, if an investor makes a mutual fund or stock-related payment through UPI, the report does not describe the 0.02% MDR as a direct additional charge that must necessarily be paid separately by that investor at the time of payment.

Instead, it becomes a payment-processing expense for the relevant financial intermediary.

Why Could Investors Still Be Affected?

Even when a charge is imposed on a business rather than directly on a customer, that business may have to decide how to manage the additional expense.

Brokerage companies and AMCs process a large volume of investment transactions. A very small percentage charge on an individual payment can therefore add up when applied across a substantial transaction base.

Experts cited in the supplied report suggest that these institutions could eventually recover some of this additional expense through their broader pricing structures.

This is why investors could experience an indirect impact even if the MDR is not separately collected from them during each UPI transaction.

What About a ₹10,000 Monthly SIP?

Consider an investor running a mutual fund SIP of ₹10,000 every month.

At an MDR rate of 0.02%, the charge mathematically associated with one ₹10,000 transaction would be:

₹10,000 × 0.02% = ₹2

If the same transaction occurs every month, the corresponding amount across 12 monthly transactions would be ₹24.

For a ₹25,000 monthly SIP, 0.02% works out to ₹5 per transaction, or ₹60 across 12 transactions.

Again, these calculations show the value of the MDR associated with the transaction. They do not establish that an investor will necessarily be charged these amounts directly.

What If You Invest ₹50,000 Through UPI?

At 0.02%, a ₹50,000 transaction corresponds to an MDR amount of ₹10.

Similarly, the calculation for ₹1 lakh comes to ₹20.

The percentage is small, but the aggregate cost can become more meaningful for financial institutions processing a very large number of transactions.

That is the main reason experts are examining whether intermediaries will absorb the expense or adjust other charges over time.

Could Brokerage Charges Increase?

The supplied information does not establish that brokerage firms or AMCs have already increased charges by a specific amount because of the new MDR.

Therefore, investors should not assume that a 0.02% MDR automatically means their brokerage fee, SIP amount or investment cost will rise by exactly 0.02%.

The possible consumer impact is described as indirect.

An intermediary could potentially absorb the expense, adjust another fee or change its pricing model, depending on the applicable regulations and its commercial policy.

Does This Mean Your SIP Investment Will Be Reduced?

Not necessarily.

For example, if you have a ₹10,000 mutual fund SIP, the existence of a 0.02% MDR does not by itself establish that only ₹9,998 will be invested and ₹2 will automatically be deducted from your investment.

According to the supplied report's framing, the MDR is payable by the AMC or brokerage firm.

Whether investors eventually face any separate or indirect additional cost would depend on how financial institutions respond to the expense and what charges they are permitted to pass on.

Why the Rule Matters Despite the Small Percentage

A rate of 0.02% appears extremely small when viewed on a single transaction.

For an individual ₹10,000 payment, it is only ₹2.

However, payment-processing economics work differently at scale. If lakhs of transactions are processed, even a small percentage can translate into a substantial overall expense for the institutions involved.

This is why the rule could matter to brokerage firms, mutual fund companies and other investment intermediaries even when its direct impact on one investor appears minimal.

What Investors Should Check

Investors using UPI for mutual fund or stock-market transactions should pay attention to the fee structure communicated by their brokerage firm or AMC.

If any institution changes its charges, investors should check exactly what the new fee is, why it is being collected and whether it is related to payment processing or another service.

The central point from the supplied report is that a 0.02% MDR applies to the specified UPI transactions and is described as payable by brokerage firms or AMCs.

Experts believe some of the cost could ultimately reach customers indirectly, but that does not mean every investor will automatically see a 0.02% charge added to each SIP or stock purchase.

For investors, the actual financial impact will therefore depend on how individual AMCs, brokers and other intermediaries handle the additional payment-processing cost.
