CBDC offers legal tender sovereign backing directly on mobile handsets without bank intermediation.

India's Unified Payments Interface (UPI) is already the undisputed crown jewel of global instant retail payments. Why, then, has the Reserve Bank of India developed the Central Bank Digital Currency (e₹)? The answer lies in sovereign liability, programmable money, and offline transaction capabilities.

#Sovereign Currency vs Bank Deposits

When you hold funds in a commercial bank account and initiate a UPI transfer, you are transferring private commercial bank liability backed by deposit insurance up to ₹5 Lakh. When you hold e₹ in your digital wallet, it is a direct claim on the central bank balance sheet, functionally identical to physical paper cash.
