UPI (Unified Payments Interface)

NPCI International's push to extend UPI beyond India is showing early commercial traction, with 1,486,537 cross-border transactions processed through December 2025 across an eight-country live network of over two million merchant acceptance points and a ninth market, Japan, entering trial on April 1, 2026.

India's central bank proposes a mandatory cooling-off window for high-value UPI and IMPS person-to-person payments, responding to a more than fortyfold increase in digital payment fraud losses between 2021 and 2025.

Worldline's CY2025 review of India's digital payments landscape quantifies UPI's expanding merchant footprint and shrinking average ticket size, reflecting the system's deepening role in everyday cash replacement.

The RBI frames the proposal around authorised push payment fraud, where victims are socially engineered into initiating transfers themselves. Transactions above ₹10,000 account for 98.5 percent of total reported fraud value.

FY26 volumes represented an 18 percent increase over FY25's 185.87 billion transactions. Merchant acceptance infrastructure expanded to 731.38 million UPI QR codes in 2025, a 15 percent year-on-year increase.

FASTag remains the primary toll payment method at standard notified rates. Commuters without a functional tag can pay via UPI at 1.25 times the regular toll fee.

CareEdge Advisory's April 2026 digital payments report finds India's payment system has reached structural digital maturity, with UPI processing over 218 billion transactions through February 2026 and digital channels accounting for 99.8 percent of all retail transaction counts in 9MFY26.

The launch extends UPI beyond retail payments into government benefit disbursement, connecting India's largest social security fund to its instant payment infrastructure.

The Reserve Bank of India's mandatory two-factor authentication requirement for all digital payments took effect on April 1, 2026. UPI services experienced widespread outages on the same day, with users at SBI, HDFC, and ICICI reporting failed transactions during financial year-end maintenance.

State Bank of India's annual closing maintenance reshaped UPI, IMPS, and internet banking services across India on April 1, coinciding with the activation of the RBI's mandatory two-factor authentication framework.

NPCI data shows UPI processed a record 22.64 billion transactions worth ₹29.53 lakh crore in March 2026. The result brings FY26's annual total to approximately 241 billion transactions.

RBI's Payments Vision 2028 proposes fifteen initiatives through December 2028, including the Payments Switching Service for bank migration, switch-on/off controls for all digital payments, shared liability for unauthorized transactions, electronic cheques, and a Cyber KRI framework for non-bank payment system operators.

EPFO 3.0 will connect India's provident fund system to UPI rails for the first time, enabling instant PF withdrawals through biometric verification with a per-transaction cap of INR 25,000. Trial runs on dummy accounts have been completed and a phased rollout starting April 2026 will expand UPI's function from retail payments into social security disbursement, adding a high-value transaction category to the platform.

NPCI BHIM Services introduced fingerprint and facial recognition authentication for UPI payments up to Rs 5,000, removing the PIN entry requirement that has contributed to an estimated 3 to 5 percent transaction failure rate. The feature launches on BHIM first with third-party UPI app integration expected to follow, arriving one week before the RBI's mandatory two-factor authentication rules take effect on April 1.

NPCI's UPI switching infrastructure experienced its fourth service disruption in March 2026, with hardware failure affecting transactions at HDFC Bank, SBI, Bank of Baroda, and Kotak Mahindra Bank on March 26. The recurring outages have prompted the Observer Research Foundation to call for structural resilience improvements as UPI processes over 20 billion monthly transactions.

IMPS daily transaction volumes have declined 22 percent from their mid-2024 peak as India's retail instant payment traffic consolidates onto UPI, which now processes more than 60 times IMPS's daily volume. With SBI introducing IMPS charges in February 2026 and average ticket sizes diverging sharply between the two systems, IMPS is transitioning from a mass-retail instant payment system to a higher-value interbank transfer channel.

The framework introduces risk-based verification across all domestic digital payment channels and expands approved authentication factors beyond SMS OTPs to include biometrics, device binding, and cryptographic keys. Compliance is required for domestic transactions by April 1 and for cross-border card-not-present transactions by October 1, 2026.

NPCI has partnered with Nvidia to develop a payments-native artificial intelligence foundation model using Nvidia's Nemotron architecture. The initiative extends NPCI's existing FiMI model, already deployed for UPI grievance handling, into fraud detection, dispute resolution, and operational optimization across India's digital payment network, which processes over 20 billion transactions monthly.

The composition of UPI traffic has shifted materially over the past year.

Government data released in March 2026 confirms UPI processed 81 percent of India's 22,168 crore retail digital payment transactions in FY2024-25. While UPI dominates retail volumes, NEFT continues growing at 32 percent annually in a higher-value corporate niche, and IMPS volumes decline below 340 million monthly as its retail role is absorbed by UPI. India's payment systems are separating into distinct tiers.
