Focus Layer: L2 Payments & Financial Rails (NPCI, UPI, RuPay)
Coverage Period: April 14-21, 2026

Executive Summary

This week’s L2 Payments & Financial Rails layer reveals India’s digital payments ecosystem continuing its unprecedented growth trajectory, with the IMF explicitly recognizing UPI as a global model for interoperability. The week also saw significant inclusivity developments, with Bank of Baroda partnering with Jio to bring banking to feature phone users—a critical gap in India’s digital financial inclusion. Meanwhile, the integration of RuPay credit cards with UPI marks a pivotal convergence of two payment ecosystems, potentially reshaping consumer credit access for millions.

Key Developments

1. IMF Recognizes UPI as Global Benchmark for Digital Payments

The International Monetary Fund has published explicit endorsement of India’s Unified Payments Interface (UPI) as a model for nations worldwide, marking a significant milestone for India’s digital public infrastructure. In its June 2025 Fintech Note titled “Growing Retail Digital Payments: The Value of Interoperability” and subsequent September 2025 feature in Finance & Development, the IMF described UPI as having “transformed the digital payments landscape in India” and noted it has become “the largest real-time payment system in the world by volume, processing more than 19 billion transactions every month.”¹

This recognition comes at a time when more than 40% of all payments in India are digital, with UPI accounting for the lion’s share—over 30 crore individuals and 5 crore merchants now use the platform. The IMF highlighted that UPI’s success demonstrates how interoperability can empower consumers, accelerate the shift away from cash, and foster innovation across the financial sector. The multilateral institution specifically credited India’s Digital Public Infrastructure approach, noting that “UPI did not succeed in isolation”—it built upon the foundation of Aadhaar and Jan Dhan Yojana, which together brought over 89% of Indian adults into the formal banking system.

The implications are twofold: first, India gains significant soft power and diplomatic leverage as other nations seek to replicate its model; second, NPCI International (NIPL) is positioned to accelerate UPI’s global expansion, with agreements already in place with financial entities in over 30 nations.

2. Bank of Baroda and Jio Launch Feature Phone Banking

In a potentially transformative move for financial inclusion, Bank of Baroda announced a partnership with Reliance Jio to launch bob World Lite—the first comprehensive mobile banking app designed specifically for feature phone users, available on the JioPhone Prima 4G device. This initiative directly addresses a critical gap in India’s digital payments landscape: while smartphone penetration has grown dramatically, hundreds of millions of Indians still use feature phones and have been largely excluded from mobile banking².

Unlike conventional banking apps that require smartphones, bob World Lite provides a full suite of everyday banking services on affordable feature phones. The partnership leverages Jio’s extensive digital reach across semi-urban and rural India combined with Bank of Baroda’s nationwide banking footprint. This aligns with the Reserve Bank of India’s vision for promoting inclusive digital payments and represents a direct response to the challenge of reaching the “last mile” in financial inclusion.

The development is particularly significant given that India’s digital payment infrastructure has historically assumed smartphone access as a baseline. By adapting banking services for feature phones, this initiative could unlock digital payments for populations previously excluded—potentially adding tens of millions of new users to the UPI ecosystem.

3. RuPay Credit Cards Integration with UPI Accelerates

The convergence of credit cards and UPI continued to gain momentum this week, with the integration now allowing RuPay credit cardholders to initiate payments using their credit lines directly through UPI. This feature combines the advantages of both credit cards (short-term credit facility) and UPI (instant, frictionless transactions), fundamentally changing how Indian consumers access credit³.

The development addresses a unique characteristic of India’s payment landscape: while credit card penetration remains lower than in developed markets, UPI adoption is massive. By enabling credit cards to work through the UPI interface, banks and card issuers can reach consumers who may have skipped traditional credit cards but are comfortable with UPI. Early data suggests this is particularly appealing to younger demographics and digital-native consumers who prefer the checkout experience of UPI over traditional card POS terminals.

This integration also creates new revenue streams for banks and payment gateways while potentially increasing credit card utility for issuers. For consumers, it offers a convenient way to access short-term credit without carrying physical cards or visiting ATMs.

4. India’s Credit-Invisible Population: The Next Frontier for Digital Finance

Economic Times analysis this week highlighted that 40-50 crore Indians remain credit-invisible or thin-file—lacking the traditional credit history that banks rely on for lending decisions. This represents one of the most significant challenges and opportunities for India’s financial infrastructure⁴.

India’s digital ecosystem captures detailed financial behavior through UPI transactions, bill payments, and recharge patterns—all providing signals of income stability and repayment discipline. The data shows that over 90% of India’s workforce is informal, lacking social security benefits, yet participating fully in the digital economy through UPI. The argument gaining traction among policymakers and fintech leaders is that this transaction data could serve as an alternative credit assessment mechanism, potentially unlocking credit for millions who would otherwise be excluded from formal credit markets.

This represents a significant cross-layer connection between L2 (Payments) and L5 (Sectoral Infrastructure), particularly in the context of credit bureaus and potential data-sharing frameworks. The challenge lies in balancing privacy concerns (relating to L7 Security) with the opportunity to extend financial inclusion.

5. International Expansion: UPI in 30+ Countries

India’s push to take UPI global continues to accelerate, with NPCI International (NIPL) now having agreements with financial entities in over 30 nations. This expansion positions UPI as a potential global standard for real-time payments, following the model of international card networks but with India’s unique value proposition: open, interoperable, and designed for emerging markets¹.

The international rollout faces challenges including regulatory approvals in different jurisdictions, currency exchange considerations, and building trusted partnerships with local financial institutions. However, India’s experience with managing a high-volume, high-frequency payment system at scale provides credibility that few other nations can match.

Cross-Layer Connections

This week’s L2 developments reveal significant interconnections with other DPI layers:

• L1 (Identity & Authentication): UPI’s growth is inseparable from Aadhaar-enabled onboarding and eKYC verification. The feature phone banking initiative specifically relies on Aadhaar verification for account opening.
• L3 (Documents & Data Exchange): Credit assessment using UPI transaction data requires APIs and data exchange frameworks that would interface with DigiLocker and account aggregators.
• L5 (Sectoral Infrastructure): The credit-invisible population challenge connects directly to the Open Credit Enablement Network (OCEN) and the broader credit infrastructure being built for MSME and consumer lending.
• L7 (Security & Privacy): As more financial data flows through UPI and credit assessment becomes more data-intensive, the DPDP Act implementation becomes critical for protecting consumer interests.
