The Paytm Payments Bank episode highlights the risks of concentration in India's digital payments ecosystem. Critically examine.

On 31 January 2024, the RBI used Section 35A of the Banking Regulation Act, 1949 against Paytm Payments Bank Ltd. (PPBL). It barred fresh deposits, wallet top-ups and FASTag credits, citing "persistent non-compliances" [1]. The episode showed how depending on one platform can turn a single firm's lapse into a wide shock. Even so, its root cause was compliance, not concentration alone.

Concentration risks the episode exposed

• Single point of failure: Paytm bundled its bank account, wallet, FASTag and UPI services in one entity, so one order froze all of them together [1].
• Consumer disruption: Users and small merchants had to find alternatives at short notice. The RBI extended the cut-off to 15 March 2024 [2].
• The "too big to discipline" dilemma: The regulator had to balance enforcement against keeping payments running. The RBI had to take additional steps, including moving Paytm's UPI handles to other banks [3].
• Ecosystem lock-in: Until December 2024, PPI wallets could be used on UPI only through the issuer's own app. This tied customers to that issuer [4].

Limits of the concentration argument

• Compliance was the trigger: The action followed audit findings and continued supervisory concerns [1]. Concentration made the damage bigger, but it did not cause the action.
• The system held up: UPI and other payment networks kept working, and users moved to other banks with little systemic disruption [3].
• Legal separation worked: Wallets are payment systems under the Payment and Settlement Systems Act, 2007 and need separate RBI authorisation [4]. One97 therefore applied for a fresh PPI licence. It got in-principle approval in November 2026, with final authorisation subject to conditions [5].
• Regulatory correction: The RBI now lets full-KYC PPI holders use third-party UPI apps, which reduces dependence on the issuer [4].

The episode shows that concentration turns one firm's compliance failure into a problem for all its users. The smooth migration and step-by-step relicensing, however, show that the regulator can handle such shocks. Going forward, India needs:

• mandatory continuity and portability plans for large fintechs;
• wider interoperability;
• compliance built into product design;
• graded supervision.

This can keep India's digital payments both inclusive and resilient, in line with SDG 8.10 and the RBI's twin goals of innovation and stability.
