UPI may remain free for users, but a proposed merchant charge could still affect prices.
The Parliament has cleared an amendment that enables banks to levy a Merchant Discount Rate (MDR) on certain UPI transactions, reopening a debate over who should bear the cost of India's hugely popular digital payment system. Finance Minister Nirmala Sitharaman has said consumers and person-to-person payments will remain free, and that no MDR framework has yet been finalised. The Editorial Team of Behind The Headlines reports that economist Ajit Ranade has challenged the argument that a merchant-only charge would have no impact on consumers. He says merchants could eventually absorb the cost or pass it on through higher prices.
The debate matters because UPI has become part of everyday life, from paying ₹20 for tea to transferring money to an auto driver. More than 85% of person-to-merchant UPI transactions are small-ticket payments, according to Ranade, making the absence of a transaction cost one of the reasons UPI became as convenient as cash. UPI processed nearly 24 billion transactions worth around ₹30 trillion in July, underlining how deeply the system is embedded in India's economy. Ranade also points out that maintaining UPI is not free: banks, payment companies and NPCI incur costs for servers, cybersecurity, fraud prevention, dispute resolution and settlement, with industry estimates putting the annual cost at around ₹20,000 crore.
The government, however, argues that the amendment does not itself introduce an MDR. It only creates the legal possibility of one being introduced later, with the UPI and Services Steering Committee headed by NPCI expected to determine its scope and structure. Sitharaman has said any future MDR would apply only to a limited category of merchant transactions above a prescribed threshold, while ordinary low-value payments would continue to remain free. Ranade's argument is that the larger question is not simply whether consumers see a fee on their UPI screen, but whether merchants eventually build the cost into the prices they charge. He has suggested that government support, including a transparent reimbursement mechanism, could help cover UPI's infrastructure costs without directly charging merchants.
What is MDR?
Merchant Discount Rate (MDR) is a fee associated with processing a digital payment. It is generally paid by the merchant to the entities involved in processing the transaction rather than being displayed as a direct charge to the customer.
The important distinction in the current UPI debate is that MDR does not automatically mean consumers will be charged for making a UPI payment.
The government has explicitly said consumers will continue to make UPI payments without a transaction charge.
The concern raised by Ranade is more indirect.
If a merchant has to pay a fee for accepting digital payments, the merchant has two broad choices:
absorb the additional cost, or
recover some or all of it through prices.
That is why the economist calls the argument that MDR cannot affect consumers “incorrect logic.”
Why was UPI kept at zero MDR?
Zero MDR helped make UPI extremely simple.
A customer could pay ₹50 to a small shopkeeper without either side having to think about a payment fee. That simplicity helped UPI compete with cash, particularly for everyday transactions.
The absence of a visible transaction cost also encouraged merchants to accept digital payments without worrying that every small transaction would reduce their margins.
This low-friction model became one of UPI's biggest strengths.
But who pays for UPI?
There is another side to the debate.
UPI may be free for users, but operating the infrastructure behind billions of transactions costs money.
Banks and payment companies have to maintain technology infrastructure, while the broader ecosystem spends on cybersecurity, fraud detection, settlement and handling payment disputes.
Ranade estimates the industry's annual UPI-related cost at around ₹20,000 crore, while government reimbursement currently covers only a fraction of that amount.
His argument is therefore not that UPI has no cost.
It is that the existence of a cost does not automatically mean the person making the payment should be charged for it.
Why does the government want the option of MDR?
The amendment gives policymakers more flexibility over how UPI's growing infrastructure costs are funded.
The government has not announced a universal UPI fee.
Instead, the legislation removes the legal restriction that had kept MDR at zero for UPI and RuPay payments, allowing a future framework to be considered.
A separate report indicates that discussions could focus on payments above ₹2,000 made to large merchants, potentially leaving the overwhelming majority of UPI transactions unaffected. However, this remains part of the emerging policy discussion and should not be treated as a final MDR structure.
The bigger question: should UPI be treated like public infrastructure?
This is at the heart of Ranade's argument.
UPI is no longer simply another payment product offered by banks or fintech companies.
It has become a major part of India's digital public infrastructure.
Its wider benefits include easier digital transactions, greater formalisation of businesses, stronger transaction records and potentially better access to digital financial services.
Ranade compares the model with Aadhaar, where the government does not charge citizens every time they use authentication because the wider benefits of having a widely used digital system are considered more important.
He has also argued that the cost of cash should be considered when comparing payment systems. Cash requires printing, transportation, storage, security, ATM infrastructure and physical handling.
In that sense, a free digital payment system can also generate savings and efficiencies elsewhere in the economy.
So, will consumers eventually pay more?
Not directly through a UPI transaction fee, based on the government's current position.
But the possibility of indirect costs cannot be completely dismissed.
If a merchant is charged MDR, the effect will depend on:
the size of the MDR;
which transactions are covered;
whether small merchants are exempt;
whether large merchants absorb the cost;
and whether businesses eventually reflect the additional expense in their prices.
That makes the final design of any MDR framework more important than the simple question of whether UPI itself remains “free”.
What happens next?
For now, UPI users can continue to make payments without a transaction charge.
The government has said that no MDR framework has yet been finalised and that any future structure will be considered by the relevant UPI and Services Steering Committee headed by NPCI.
The real policy challenge is therefore finding a sustainable way to fund an infrastructure that handles billions of transactions without undermining the very feature that made UPI successful: simplicity and zero-friction payments.
The question India now faces is not simply “Who should pay for UPI?”
It is “How can India keep the world's most widely used instant-payment system affordable without making its enormous infrastructure costs unsustainable?”
