RBI Digital Rupee (CBDC) 2026: e-Rupee & Key MCQs

The Reserve Bank of India officially designated its central bank digital currency as the Digital Rupee, symbolized by e₹.

Section 2(a-iv) of the RBI Act was amended to include banknotes in digital form, making e₹ a direct sovereign liability of the central bank.

e₹-W launched on 1st November 2022 for interbank settlement of government securities, followed by e₹-R on 1st December 2022 for consumer retail payments.

The Digital Rupee is sovereign legal tender and a direct claim on the RBI, carrying zero risk of default or market volatility.

Retail e₹ mirrors physical cash notes and coins digitally, complete with digital serial numbers and unique central bank signatures.

In UPI, the payment involves bank-to-bank settlement across intermediary ledgers. In CBDC, the transaction itself is the ultimate final settlement.

Atomic DvP ensures that the transfer of government securities occurs if and only if the transfer of digital cash occurs, removing settlement default risk.

Direct CBDC linkages streamline bilateral trade invoicing in rupees, reducing transaction costs and exposure to foreign currency exchange risks.
