When the RBI issued payment bank licenses in 2015, the concept seemed promising. A new category of bank focused purely on payments and deposits — no lending allowed — operating at lower cost with digital-first models to serve the underbanked.

Bharti Airtel, Vodafone Idea, India Post, Paytm, Fino, and Reliance Industries all launched payment banks. They were supposed to complement traditional banks by focusing on small-value transactions, remittances, and basic savings accounts for people outside the formal banking system.

Seven years later, the payment bank experiment is looking less successful than originally hoped. Several have shut down. Others are struggling financially. The few that remain viable have had to pivot significantly from their original models.

The Business Model Problem

Payment banks can accept deposits and facilitate payments, but they can’t lend. All deposits must be parked in government securities or deposited with other banks. This creates a fundamental profitability challenge.

Traditional banks make money primarily through net interest margin — the spread between what they earn from lending and what they pay on deposits. Payment banks don’t have that revenue stream.

Instead, they depend on:

• Transaction fees from payments processing
• Cross-selling financial products from partners
• Value-added services built on top of the banking platform
• Interchange fees from card transactions

None of these revenue sources, individually or combined, has proven sufficient to sustain the business model at scale. Transaction fees in India’s digital payments ecosystem are minimal due to regulatory caps and competitive pressure. Cross-selling financial products produces limited revenue when your customer base is primarily low-income users making small transactions. Value-added services remain largely aspirational.

The result is that most payment banks lose money. Airtel Payments Bank reported losses for years before recently approaching break-even through aggressive cost management. Paytm Payments Bank has been heavily subsidized by its parent company. Others simply gave up.

UPI Undermined the Value Proposition

When payment banks launched, India’s digital payments landscape looked different. UPI didn’t exist yet. Digital payments meant wallets, cards, or proprietary bank systems.

Payment banks positioned themselves as digital-first alternatives that would make payments easier and more accessible than traditional banks. That value proposition made sense in 2015.

By 2017, UPI was live. By 2019, it dominated. By 2026, UPI processes over 12 billion transactions monthly and is the default digital payment method for most Indians.

UPI is bank-agnostic, interoperable, and free for consumers. Any bank account can send and receive UPI payments. Payment banks offered nothing distinctly better in the UPI era. The convenience advantage they were supposed to provide evaporated.

Limited Deposit Growth

Payment banks are allowed to accept deposits up to ₹2 lakh per customer. This limit, designed to distinguish them from full-service banks, turned out to be a significant constraint.

Customers comfortable keeping meaningful money in a bank account want the services of a full bank — lending, credit cards, investment products. Those who only need basic payment and savings services often don’t maintain large balances.

Payment banks have struggled to grow deposit bases beyond initial customer acquisition drives. Without significant deposits, they lack the scale needed to make transaction-based revenue models work.

RBI data shows that total deposits across all remaining payment banks are a tiny fraction of the banking system’s overall deposits. They haven’t become meaningful players in deposit mobilization.

Regulatory Constraints

The restrictions that define payment banks — no lending, limited deposit size, constrained investment options — make sense from a financial stability perspective. But they also limit business model flexibility.

Payment banks have lobbied for relaxation of rules, particularly around lending. Allow small-ticket personal loans or credit. Let deposit limits increase. Permit a wider range of investment instruments.

The RBI has been cautious. The payment bank category was created specifically to be a narrow, low-risk subset of banking. Expanding it too much would blur the distinction with small finance banks or full commercial banks.

This leaves payment banks stuck. The original model doesn’t work financially, but regulatory constraints prevent pivoting to something more viable.

What’s Surviving

Two payment banks have found relatively stable models:

India Post Payments Bank benefits from massive distribution through post offices and serves a genuine financial inclusion role in areas where banking access is limited. It’s not profitable, but it operates as a public service rather than a commercial venture.

Airtel Payments Bank tied payments to Airtel’s core telecom business, creating cross-selling opportunities and benefiting from Airtel’s customer base. By keeping operations lean and integrating tightly with the parent company, it’s approaching viability.

Others have exited or remain loss-making. Vodafone Idea shut down its payment bank in 2022. Aditya Birla Idea Payments Bank closed in 2019. Paytm Payments Bank has faced regulatory challenges and continues operating primarily as infrastructure for its parent company’s fintech platform rather than a standalone business.

The Underlying Miscalculation

The payment bank concept assumed that digital payments would remain fragmented and that specialized institutions focused on payments could carve out profitable niches. That assumption was wrong.

UPI unified India’s digital payments into an interoperable network where any bank can participate on equal terms. Specialized payment-focused institutions don’t have an inherent advantage.

The second miscalculation was around serving low-income customers profitably. Financial inclusion is socially valuable, but providing banking services to customers making small, infrequent transactions is expensive relative to revenue generated. Without cross-subsidy from higher-margin products (which traditional banks have through lending), the economics don’t work.

Where This Leaves Financial Inclusion

Payment banks were supposed to advance financial inclusion. Their limited success doesn’t mean financial inclusion has stalled — it means other mechanisms have been more effective.

Jan Dhan accounts, UPI, and the banking correspondent model have brought hundreds of millions into the formal financial system. Traditional banks, incentivized and sometimes mandated to serve rural and low-income customers, have expanded reach.

Payment banks were one experiment among many. It didn’t work as well as hoped, but other approaches did.

The Bigger Lesson

Specialized institutional categories work when they provide clear advantages over general-purpose competitors. Small finance banks have a distinct value proposition around serving segments that traditional banks underserve, with lending capabilities that make them financially sustainable. Payment banks had neither a clear advantage nor a sustainable business model.

Creating new banking categories sounds innovative, but unless they solve a problem existing institutions can’t or won’t solve, they struggle to find viability.

India’s payment bank experiment was worth trying. It taught useful lessons about digital financial services, regulatory design, and the challenges of serving low-income customers profitably. But as a long-term model, it’s fading. Don’t expect many new payment bank licenses or significant growth from existing ones. The category served its purpose as an experiment. The experiment has largely concluded.
