What do you mean by Digital Rupee? In this context, explain the working and progress of India's Central Bank Digital Currency (CBDC).
Syllabus: Indian economy — mobilization of resources; inclusive growth
Three things: define the Digital Rupee, explain how it works, and give the progress of the pilots. The working half is where most answers go thin, and where the marks are, so be specific about the token model, the two-tier distribution and what makes it different from a bank deposit or UPI.
- Define with the three properties that matter: sovereign liability, legal tender, digital form.
- Explain the architecture — wholesale and retail, two-tier distribution through banks, token-based wallets, anonymity and offline capability, programmability.
- Give dated progress and then the honest assessment of why adoption remains small next to UPI.
What it is. The Digital Rupee, or e-rupee, is India's Central Bank Digital Currency: a sovereign currency issued by the Reserve Bank in digital form. It is a liability of the RBI, not of a commercial bank, it is legal tender, and it is exchangeable at par with cash and bank deposits. That distinguishes it from a bank deposit, which is a claim on a bank, from UPI, which is a messaging layer that moves deposits, and from a private cryptocurrency, which has no issuer standing behind it.
How it works
- Two variants. Wholesale CBDC (e₹-W), for settlement between financial institutions, and retail CBDC (e₹-R), for person-to-person and person-to-merchant payments.
- Two-tier distribution. The RBI issues to banks; banks distribute to users through CBDC wallets. The central bank does not maintain retail accounts, so the existing banking relationship is preserved.
- Token, not account. e₹-R is issued in the same denominations as notes and coins and held as digital tokens in a wallet, so it behaves like cash rather than like a balance.
- Cash-like features. It bears no interest, and it is designed for a degree of anonymity in small transactions and for offline functionality in areas of poor connectivity, which UPI cannot offer.
- Programmability. Because the token can carry conditions, CBDC can be restricted to a purpose, a merchant category or a validity period, which is what makes it interesting for subsidy delivery.
Progress
- Pilots began with wholesale on 1 November 2022, for settlement of government securities transactions, and retail on 1 December 2022, in closed user groups of customers and merchants.
- The retail pilot was progressively widened to more banks, cities and use cases, reaching several million users, with interoperability with UPI QR codes so that a CBDC wallet can pay at an existing merchant.
- Programmability has been tested for targeted transfers, including tying funds to specified purposes such as agricultural inputs and subsidised food, so that the money can only be spent where it was intended.
- Cross-border and wholesale applications are being explored, and the RBI has repeatedly said there is no target date for a full launch, since the pilots are designed to learn rather than to scale.
Assessment. Volumes remain a small fraction of UPI, and this is unsurprising: UPI already works, is free at point of use, and there is little reason for a consumer to switch. The genuine case for CBDC in India is therefore not retail payments but the things UPI cannot do, offline transactions, programmable public expenditure and cheaper cross-border settlement, and the risks that must be managed are disintermediation of bank deposits, privacy of transaction data, and cyber resilience.
Value addition that earns marks
- The clean one-line differentiator: UPI moves commercial bank money, CBDC is central bank money. Very few answers state this precisely, and it settles half the question.
- Legal basis matters: the RBI Act was amended through the Finance Act, 2022 to include currency in digital form within the definition of bank note, which is what makes e₹ legal tender.
- Programmability tested for subsidy and welfare delivery is the policy-relevant frontier, and it connects directly to the PDS case study in the same year's GS4 paper.
- Flag the risk honestly: full-scale retail CBDC could drain bank deposits in a stress episode, which is why design caps and non-remuneration are deliberate choices.
Where answers lost marks
- Describing CBDC as a cryptocurrency or as blockchain-based by necessity. The design is technology-neutral and the token is a sovereign liability.
- Confusing e-RUPI, a prepaid voucher, with e₹, the central bank digital currency. They are different instruments.
- Quoting user or transaction numbers without a date. Give the figure with its as-of date or describe the trend instead.
