Digital rupee (e₹) and UPI: central bank money versus a payment rail
Why in news: The Reserve Bank of India updated its digital rupee FAQs as on 1 October 2026, setting out how e₹ differs from UPI.
The digital rupee (e₹) is India's Central Bank Digital Currency (CBDC): a digital form of the rupee note, issued by the Reserve Bank of India, held in a wallet and accepted as legal tender. The Unified Payments Interface (UPI) is a payment system that moves money between bank accounts. RBI's FAQs, updated on 1 October 2026, set out this difference.

Why this matters for UPSC
GS3 Indian economy, money and payment systems: Prelims can ask whether e₹ is legal tender, earns interest or can be programmed, and who runs UPI; Mains, whether a CBDC can improve welfare delivery without eroding privacy.
In short
The digital rupee (e₹) is central bank money in digital form, legal tender issued by the Reserve Bank of India, whereas UPI is a channel moving bank deposits.
The e₹ should complement UPI rather than compete with it, earning its place through programmable welfare and wholesale settlement while protecting users' privacy.
Why it matters
For a shopper, paying by UPI or by e₹ feels the same: scan a code and pay. The difference lies in what is held. A UPI user's money sits in a bank account, so it depends on that bank. An e₹ balance is a claim on the RBI itself, like a note in a purse, and it earns no interest. The bigger change is for welfare. A farmer can receive a subsidy that can be spent only at approved equipment dealers, so the money cannot be diverted and the farmer pays nothing upfront. The same feature worries critics, who fear that money with conditions attached gives the state too much say over how people spend.
Prelims pointers
- Section 22, RBI Act, 1934: the source of the RBI's statutory power to issue bank notes and manage the currency.
- RBI Concept Note (October 2022): design choices are retail or wholesale, direct or indirect model, token or account form, remuneration and anonymity.
- Token-based CBDC is the Concept Note's preferred form for retail use, being closer to cash; account-based CBDC may be considered for wholesale.
- UPI was launched on 11 April 2016 by the National Payments Corporation of India under the regulatory oversight of the RBI.
- UPI processed over 24,162 crore transactions in FY 2025-26, per PIB citing NPCI data.
- e₹ carries no interest because a deposit-like CBDC could draw funds out of banks and weaken credit creation, the Concept Note says.
Practise a UPSC-style question
With reference to the digital rupee (e₹) issued by the Reserve Bank of India, consider the following statements:
1. Being a digital form of the bank note, e₹ is legal tender under the Reserve Bank of India Act, 1934.
2. Balances held in an e₹ wallet earn interest at the savings deposit rate of the bank offering the wallet.
Which of the statements given above is/are correct?
- (a) 1 only
- (b) 2 only
- (c) Both 1 and 2
- (d) Neither 1 nor 2
Show the answer
Answer: (a) 1 only
Answer: (a) 1 only. e₹ is legal tender like a note, and like cash it pays no interest.
Statement 1: correct. Section 26 of the RBI Act, 1934 makes every bank note legal tender; e₹, the digital form of the note, is legal tender and a liability of the RBI.
Statement 2: incorrect. Given its cash-like features, no interest is payable on e₹ wallet balances, the RBI's FAQs state.
Eliminate: Statement 2 treats e₹ like a bank deposit, which it is not, so it is incorrect. Out: (b), (c).
Eliminate: Statement 1 follows from e₹ being a bank note in digital form, so it is correct. Out: (d).
Trap: Sounds right. Interest on a wallet balance seems natural for a bank app, but e₹ copies cash, which earns nothing.
Remember: e₹ = digital cash: legal tender, RBI liability, zero interest.
