Why Do We Need One More Form of Digital Money- e₹ in Financial Markets?
Digital Forms of Money Today: The Missing Central Bank Digital Link
There are various ‘Digital Forms of Money’ available to the public today for ‘Store of Value and for Payments’, including Regular Bank Deposits of Commercial Banks accessed through Banking Apps and Debit Cards. Another widespread arrangement is payment transactions through ‘Credit Cards’ or ‘Closed Systems’ such as PhonePe, Google Pay, Paytm, Amazon Pay, BHIM, FreeCharge, JioMoney, Mobikwik, Airtel Money, and Pockets by ICICI Bank.
Furthermore, commercial banks, financial market utilities, and institutional participants have digital access to central bank reserves (such as Cash Reserve Ratio account maintenance with the RBI).
1. Present Payment Systems, Network Effects & Systemic Risk
Payment network effects increase the value of the network exponentially for participants and the public as adoption expands. However, these powerful network effects have generated severe market concentration and vulnerabilities:
Monopoly Power & Barriers to Entry
Network consolidation creates significant barriers to entry for newer fintech entities, even when they possess superior technology. Merging payment networks concentrates monopoly power, resulting in higher transaction costs imposed on small merchants and individuals.
Systemic Risk in Closed Private Systems
Concentration of the national payment rail in a handful of private enterprises heightens systemic risk. If a private payment giant experiences operational insolvency or technical failure, citizens and commerce face severe disruption. CBDC provides a resilient public alternative independent of private failures.
Friction in Cross-Border Remittances
Global supply chain integration and massive inbound remittances require efficient cross-border settlement. Current systems rely on correspondent banking (Nostro accounts) and multi-layered messaging, resulting in friction, delays, and exorbitant fees. CBDC simplifies and expedites cross-border flows.
Payments Vision 2025: Strategic Objectives
Payment systems underpin economic development, financial stability, and financial inclusion. Ensuring safe, secure, reliable, accessible, affordable, and efficient payment systems remains a core strategic goal of the Reserve Bank of India (RBI).
Over the past decade, India has engineered one of the most modern payment infrastructures globally across retail, fast, and wholesale segments. In doing so, the role of the RBI has transformed from being purely a regulator, operator, and facilitator to becoming the proactive creator of an environment for the structured development of India’s digital payments ecosystem.
2. Architecture, Process & Pilot Launch of the Digital Rupee (e₹)
The Central Bank Digital Currency is designed to coexist alongside all other forms of physical and electronic fiat currency for the short to medium term. Programmable money allows dynamic interest rate setting and advanced smart settlement features.
1. Retail CBDC: e₹-R (General Purpose)
Available to non-financial consumers, private sector enterprises, merchants, and the general public for daily retail commerce, P2P money transfers, and P2M consumer payments.
2. Wholesale CBDC: e₹-W
Restricted to selected financial institutions for high-value interbank transfers, call money market operations, short-term money markets, and government securities (G-Sec) market settlements.
RBI Phase-Wise e₹ (R) Pilot Implementation (Commenced 1st December 2022)
- State Bank of India (SBI)
- ICICI Bank
- Yes Bank
- IDFC First Bank
- (4 additional banks join in Phase 2)
- Mumbai
- New Delhi
- Bengaluru
- Bhubaneswar
Operational Mechanics of e₹ (R) Transactions:
- Closed User Group (CUG): The pilot operates within a CUG comprising selected participating merchants and customers across designated geographic locations.
- Exact Denomination Parity: e-Rupee tokens are issued in the exact same denominations as physical currency notes and coins (₹1 to ₹2,000 denominations).
- Two-Tier Intermediated Distribution: The RBI issues digital tokens, while commercial banks act as intermediary distribution points.
- Bank-Provided Digital Wallets: Users store and transact e₹ via specialized smartphone or laptop wallet applications hosted by participating banks.
- P2P & P2M Transaction Modalities: Supports Person-to-Person (P2P) transfers and Person-to-Merchant (P2M) retail checkouts using merchant QR codes displayed at shops and malls.
3. Value Proposition and Direct Benefits to the Public
Retains safety, instant settlement finality, sovereign backing, and inherent public trust identical to physical fiat cash.
Flexible legal tender usable even by unbanked individuals without requiring a commercial bank account, fostering true financial inclusion.
Immune to physical degradation; cannot be torn, burnt, soiled, or subjected to environmental wear and tear.
Unlike volatile private cryptocurrencies, CBDC is governed directly by the RBI, eliminating speculative volatility and credit risk.
Freely convertible into physical cash or commercial bank deposits at a guaranteed 1:1 par value (though e₹ itself does not earn interest).
Private wallet balances and electronic commercial credits cannot legally or operationally replace sovereign CBDC digital money.
4. Comprehensive Risk Analysis of CBDC Deployment
1. Privacy Concerns & Anonymity vs. Cash
The central bank could potentially handle enormous databases of individual transaction footprints. Digital currencies cannot natively replicate the complete anonymity and privacy of physical cash transactions. Compromise of user credentials poses another severe institutional risk.
2. Disintermediation of Commercial Banks
A broad-based consumer shift to CBDC could significantly undermine commercial banks’ deposit base, restricting their ability to plough back funds into productive credit intermediation.
If e-cash expands without regulatory holding limits on mobile wallets, weaker banks will struggle to retain low-cost CASA (Current Account Savings Account) deposits.
3. Operational, Cybersecurity & Obsolescence Risks
- Rapid Technology Obsolescence: Accelerating technological change threatens CBDC architecture, demanding continuous high-cost capital upgrades.
- Operational Retraining: Intermediary bank staff must be groomed, certified, and retrained to operate securely in the CBDC ecosystem.
- Elevated Cyber Vulnerabilities: Demands perpetual penetration testing, firewall defenses, and cryptographic safeguards against sovereign cyber warfare.
- Central Bank Operational Burden: Substantial administrative, maintenance, and technical costs incurred by the RBI in managing CBDC issuance and clearing infrastructure.
5. Efficacy of Monetary Policy Implementation
Widespread migration of citizens to private digital currencies or stablecoins (cryptocurrencies pegged to external assets) threatens central banks with loss of monetary sovereignty and policy control. A sovereign CBDC establishes an essential direct transmission channel:
Central Bank Digital Currency does not alter the fundamental system of monetary policy; rather, it facilitates the timely, friction-free transmission of policy actions across economic agents. By introducing CBDC, the central bank can break through the ‘Zero Lower Bound’ constraint of physical cash during economic slumps, or curb inflationary pressures via positive policy interest rates.
Three Foundational Policy Design Dimensions for Central Banks:
- Remuneration Structure: Whether CBDC is Non-remunerated (bearing 0% interest, akin to cash) or Remunerated (bearing variable policy interest rates).
- Accessibility Horizon: Whether extensively accessible to the retail public like physical cash, or restricted to wholesale financial institutions like bank reserves.
- Anonymity vs. Identifiability: Whether unnamed/anonymous like physical bank notes, or identity-tracked with an immutable audit trail of account entries.
Tail-Risk: Acceleration of Systemic Bank Runs & Credit Costs
In normal economic conditions, economic agents (households, businesses, governments) prefer interest-bearing bank deposits over non-remunerated CBDC. However, during systemic tail-risk events or bank distress, CBDC serves as a risk-free safe haven guaranteed by the central bank.
The seamless digital transfer from bank deposits to CBDC could dramatically accelerate bank runs. If commercial banks lose durable liquidity to CBDC, they must compete aggressively for deposits by hiking deposit rates. This forces an increase in retail lending rates and a contraction in aggregate credit availability, impacting macroeconomic supply and demand.
6. Summary Impact of CBDC on Key Monetary Variables
| Monetary Variable | Non-Remunerated CBDCs | Remunerated CBDCs |
|---|---|---|
| Reserve Money | Yes / No | Yes |
| Money Supply | No | Yes |
| Velocity | No | Yes |
| Money Multiplier | Yes / No | Yes |
| Liquidity Conditions / LAF | Yes / No | Yes |
| Monetary Policy (Repo Rate) | No | Yes |
7. Conclusion & The Road Ahead
The Reserve Bank of India’s pilot launch of the Central Bank Digital Currency marks a historic milestone in India’s monetary evolution. CBDC holds immense promise by ensuring complete transparency, low transaction costs, and expanding digital financial access to a wider populace.
“While the intent of Central Bank Digital Currency and the expected benefits are well understood, in the absence of global precedence, extensive stakeholder consultation along with iterative technology design must take place. It is imperative to identify innovative methods and compelling use cases that will make Central Bank Digital Currency as attractive as cash, if not more.”
