Indian Overseas Bank has launched the IOB Digital Rupee app, a retail application for the central bank digital currency that lets customers hold e₹ wallets and make person-to-person and person-to-merchant payments. The IOB Digital Rupee app is interoperable with UPI and supports programmable CBDC features intended for grants and direct benefit transfers. The launch was announced on 9 November 2026.
The bank is joining a retail CBDC network that already includes private-sector and fintech wallets. HDFC Bank has offered interoperability between the digital rupee and UPI and has integrated CBDC into its SmartGateway payments stack, while MobiKwik has rolled out a full-scale CBDC wallet.
What the IOB Digital Rupee app offers
Customers can use the app to transact in the digital rupee through e₹ wallets, for transfers between individuals and for payments to merchants. UPI interoperability is intended to let those wallets work with the existing UPI acceptance network rather than sitting in a closed CBDC loop. The bank has also pointed to programmable CBDC, which can restrict or route funds for defined uses such as government grants and direct benefit transfers.
Programmable CBDC has been part of the Reserve Bank’s recent conversations with state governments on benefit delivery, as set out when Governor Sanjay Malhotra discussed the Unified Lending Interface, programmable CBDC and DBT with state finance secretaries. IOB’s app puts a public sector bank interface on that design, alongside the private-bank and fintech wallets already in the market.
Where it sits in the digital rupee rollout
The retail digital rupee remains a pilot that banks offer through their own applications. Each new bank app widens the number of customers who can open an e₹ wallet without leaving their primary bank. Interoperability with UPI is the feature that determines whether those wallets can be spent at the QR codes already on merchant counters. IOB has not, in the announcement reported, given a figure for how many customers will be onboarded at launch, and no such number is used here.
