Digital Rupee (e₹): India's CBDC Pilot, Explained

India is running one of the largest CBDC experiments in the world — and one of the most instructive, because it launched into a country that already solved instant payments. The digital rupee’s struggle isn’t technology; it’s finding a reason to exist next to UPI.

What the digital rupee is

The e₹ is a central bank digital currency issued by the Reserve Bank of India — a direct digital claim on the RBI, distributed through banks into customer wallets. Two parallel pilots have run since late 2022:

  • e₹-W (wholesale) — launched November 2022 for interbank settlement, initially targeting secondary-market government securities.
  • e₹-R (retail) — launched December 2022, expanded from an initial cohort of banks and cities to a multi-million-user pilot with person-to-person and person-to-merchant payments.

Both use a token-based design on permissioned infrastructure — consistent with every live CBDC worldwide (see the CBDC tracker for the pattern).

The UPI problem — and pivot

India’s Unified Payments Interface processes billions of transactions a month, is free for consumers, and works everywhere. A retail CBDC offering “instant digital payments” solves a problem Indians don’t have. Adoption numbers told that story early: after an initial push (reportedly aided by banks seeding wallets), organic daily usage stayed far below UPI’s scale.

The RBI’s response has been pragmatic rather than promotional:

  1. Interoperability with UPI QR codes — e₹ wallets pay at existing UPI merchants, removing the acceptance-network problem entirely.
  2. Offline payments — pilots for areas with poor connectivity, something UPI fundamentally can’t do (it needs the bank rails online). This is the digital rupee’s clearest differentiator.
  3. Programmability pilots — purpose-bound transfers like targeted subsidies and corporate expense controls (the constructive face of programmable money).
  4. Non-bank distribution — payment apps were permitted to offer e₹ wallets, widening beyond bank apps.

Why the wholesale track matters more

The quietly important work is e₹-W. India runs capital controls; cross-border settlement in central-bank money — without correspondent banks — is strategically valuable in a way domestic retail payments are not. The RBI has been explicit about exploring cross-border CBDC connectivity, and India’s participation in multi-CBDC bridge discussions aligns with the broader pattern: wholesale designs are where CBDCs make obvious sense; retail designs hunt for a use case.

How India compares

The common thread: every retail CBDC launches into competition with an entrenched, excellent private payment system, and has to find the gaps (offline, programmability, sovereignty) rather than win head-on. India is the cleanest demonstration because UPI is the world’s best incumbent.

What to watch

  • Whether offline e₹ moves from pilot to general availability — the first genuine UPI-beating feature.
  • Wholesale cross-border corridors (the RBI has signaled UAE and others).
  • Any move from “pilot” to formal launch — the RBI has consistently refused to commit to a date, and as of mid-2026 the e₹ remains officially a pilot.
