Question
Which one of the following statements about Unified Payments Interface (UPI) and Central Bank Digital Currency (Digital Rupee) is NOT correct?
AUPI is a real-time payment system but Digital Rupee is akin to sovereign paper currency.
BIn case of UPI, settlement for end users happens instantly as the money gets immediately debited or credited but in case of Digital Rupee, there is no settlement as the wallet balance gets transferred to another wallet.
CUPI transactions are recorded by banks and reflected in bank statements but in case of Digital Rupee, no data is captured in bank statements as transactions are from one wallet to another.
DIn both the cases (UPI and Digital Rupee), the liability lies with the users and their respective banks.
Each Statement — Verified Against RBI Framework
A
✓ Correct statement
UPI is a real-time payment system but Digital Rupee is akin to sovereign paper currency.
Correct.• UPI = a payment system/rails — it moves money between bank accounts in real time. The money itself remains bank money (demand deposits).
• Digital Rupee (e₹) = the currency itself — issued by RBI as legal tender, equivalent in value to paper currency. Just as a ₹500 note is sovereign currency, a ₹500 Digital Rupee is sovereign currency — but in digital form.
The key distinction: UPI is a method of payment; Digital Rupee is a form of money.
✓ Correct — UPI = payment rails · Digital Rupee = sovereign currency in digital form
UPI moves bank money · Digital Rupee IS the money · Analogous to NEFT/RTGS (payment systems) vs physical cash (currency)
B
✓ Correct statement
In UPI, settlement happens instantly; in Digital Rupee, there is no settlement as wallet balance transfers to another wallet.
Correct.• UPI: Money moves from Payer’s bank account → Payee’s bank account. Banks settle with each other (even if near-instantly for end users). There is an underlying interbank settlement process.
• Digital Rupee: The e₹ itself moves from one digital wallet to another — like handing a ₹500 note to someone. The currency transfers directly, requiring no settlement between banks. The transaction is final when the wallet balance changes.
✓ Correct — UPI has settlement between banks · Digital Rupee = cash-like direct transfer, no settlement
Think of UPI as a cheque clearing process (fast) · Digital Rupee as handing over a ₹100 note — the currency itself moves
C
✓ Correct statement
UPI transactions reflected in bank statements; Digital Rupee transactions not captured in bank statements.
Correct.• UPI: All transactions flow through banks (debits and credits to bank accounts). Banks record every transaction → reflected in account statements.
• Digital Rupee: Transactions occur between digital wallets — similar to cash transactions between individuals. Just as a ₹1,000 cash payment doesn’t appear in your bank statement, a ₹1,000 Digital Rupee transfer doesn’t automatically appear in a bank statement (though CBDC wallets are separately maintained and may have their own records).
Note: This also has implications for financial privacy and AML/KYC compliance — an important policy debate around CBDCs.
✓ Correct — UPI appears in bank statements · Digital Rupee = cash-equivalent, no bank statement entry
Digital Rupee transactions are wallet-to-wallet · Like cash, not recorded in bank statement · CBDC wallets are separate from bank accounts
D
✗ NOT Correct — The answer to eliminate
In both UPI and Digital Rupee, the liability lies with the users and their respective banks.
Incorrect — the liability structure is fundamentally different between UPI and Digital Rupee:• UPI: The bank deposits (money in savings accounts) are liabilities of the respective commercial banks. When you pay via UPI, your bank’s liability to you decreases and the payee’s bank’s liability to the payee increases. NPCI operates the rails.
• Digital Rupee: The e₹ is a direct liability of the Reserve Bank of India — the central bank and currency issuer. Just as a physical ₹500 note is an RBI liability (“I promise to pay the bearer a sum of ₹500”), the Digital Rupee is an RBI liability. Commercial banks are NOT liable for Digital Rupee transactions — they only serve as distribution intermediaries.
Statement D is wrong because it says liability lies with “users and their respective banks” in BOTH cases. For Digital Rupee, liability lies with the RBI — not with commercial banks.
✗ Wrong — Digital Rupee liability = RBI (not commercial banks)
UPI = liability of commercial banks (deposits) · Digital Rupee = liability of RBI (sovereign currency issuer) · Banks only distribute e₹, not liable for it · This is why CBDC is called “central bank” digital currency
UPI vs Digital Rupee — Complete Comparison
| Feature | UPI | Digital Rupee (e₹ / CBDC) |
| Nature | Payment system/rails — moves bank money | Sovereign currency — IS the money itself |
| Issued by | NPCI (National Payments Corporation of India) | RBI (Reserve Bank of India) |
| Liability | Commercial banks (deposits are bank liabilities) | RBI (digital currency is RBI’s direct liability) |
| Settlement | Interbank settlement required (fast but necessary) | No settlement needed — currency itself moves (wallet to wallet) |
| Bank statements | Yes — all UPI transactions appear in bank account statements | No — wallet-to-wallet like cash, not in bank statements |
| Underlying money | Commercial bank money (deposits) | Central bank money (equivalent to physical currency) |
| Analogy | Like NEFT/RTGS/cheque — a payment mechanism | Like physical cash — the currency itself, but digital |
| Privacy | Full bank record exists · Traceable | Programmable privacy possible · Closer to cash |
Memory Trick
🧠 The Core Distinction — Liability
Digital Rupee = RBI’s liability, not the bank’s: Every physical ₹100 note says “I promise to pay the bearer ₹100” — signed by the RBI Governor. The Digital Rupee is the same promise, in digital form. The commercial bank just distributes it — like a post office delivering money — the bank is not responsible for the value.
UPI = bank deposits → bank’s liability: Your ₹10,000 in a savings account is the bank’s liability to you (the bank owes you ₹10,000 on demand). UPI moves these bank liabilities between accounts. If the bank fails, deposit insurance (DICGC) kicks in — not RBI directly.
Why “Central Bank” in CBDC matters: CBDC = Central Bank Digital Currency. The “central bank” part means the RBI bears the liability — not commercial banks. This is the most important conceptual distinction and the basis of option D being wrong.
