RBI Governor Discusses Anonymity in Digital Currency


RBI Governor Shaktikanta Das emphasized the importance of avoiding permanent deletion of transactions in the e-rupee or central bank digital currency (CBDC). He highlighted that such deletion could render the digital currency anonymous, similar to paper currency, speaking at the BIS Innovation Summit.

Key Highlights of the Speech Delivered by RBI Governor:

  • CBDC Development: The RBI Governor highlighted ongoing efforts to enhance Central Bank Digital Currency (CBDC) functionality, aiming to enable offline transfers and introduce programmability to support financial inclusion objectives.
  • Privacy Concerns: Concerns regarding CBDC’s impact on privacy have been raised since its introduction in late 2022. Experts suggest that unlike cash, CBDC transactions may not offer anonymity due to their electronic nature.
  • Addressing Anonymity: The Governor proposed addressing anonymity concerns through legislation or technology solutions, such as implementing permanent deletion of transactions. The goal is to ensure CBDC offers the same level of anonymity as cash.
  • Preference for UPI: Despite RBI’s efforts in CBDC development, retail users continue to prefer the Unified Payment Interface (UPI) for their transactions.

What is E-rupee?

  • E-rupee is the same as a fiat currency and is exchangeable one-to-one with the fiat currency. 
  • Only its form is different. It can be accepted as a medium of payment, legal tender and a safe store of value.
  • The digital rupee would appear as liability on a central bank’s balance sheet.
What are the types of e-rupee?

Based on the usage and the functions performed by the digital rupee and considering the different levels of accessibility, CBDC can be demarcated into two broad categories —

Retail CBDC

  • It is an electronic version of cash primarily meant for retail transactions.
  • It will be potentially available for use by all — private sector, non-financial consumers and businesses — and can provide access to safe money for payment and settlement as it is a direct liability of the central bank.
  • However, the RBI has not explained how e-rupee can be used in merchant transactions in the retail trade.

Wholesale CBDC

  • It is designed for restricted access to select financial institutions.
  • It has the potential to transform the settlement systems for financial transactions undertaken by banks in the government securities (G-Sec) segment, inter-bank market and capital market more efficiently and securely in terms of operational costs, use of collateral and liquidity management.

What are the forms of CBDC?

The central bank says e-rupee, or CBDC, can be structured as

Token-based CBDC

  • It would be a bearer instrument like banknotes, meaning whosoever holds the tokens at a given point in time would be presumed to own them.
  • In a token-based CBDC, the person receiving a token will verify that his ownership of the token is genuine.
  • A token-based CBDC is viewed as a preferred mode for CBDC-R as it would be closer to physical cash.

Account-based system

  • It would require maintenance of record of balances and transactions of all holders of the CBDC and indicate the ownership of the monetary balances.
  • In this case, an intermediary will verify the identity of an account holder.
  • This system can be considered for CBDC-W.

What’s the model for issuance?

There are two models for issuance and management of CBDCs under the RBI’s consideration —

Direct model (single tier model)

  • The central bank will be responsible for managing all aspects of the digital rupee system such as issuance, account-keeping and transaction verification.

Indirect model (two-tier model)

  • An indirect model would be one where the central bank and other intermediaries (banks and any other service providers), each play their respective role.
  • In this model, the central bank will issue CBDC to consumers indirectly through intermediaries and any claim by consumers will be managed by the intermediary.

What are the advantages of e-rupee?

  • Reduction in operational costs involved in physical cash management,
  • It will foster financial inclusion,
  • It will bring resilience, efficiency and innovation in the payments system.
  • It will add efficiency to the settlement system and boost innovation in cross-border payments space and provide the public with uses that any private virtual currencies can provide, without the associated risks.

Can e-rupee be transacted in offline mode?

  • The offline functionality as an option will allow CBDC to be transacted without the internet and thus enable access in regions with poor or no internet connectivity.
  • It will also create digital footprints of the unbanked population in the financial system, which will facilitate the easy availability of credit to them.
  • However, the RBI feels in the offline mode, the risk of ‘double-spending’ will exist because it will be technically possible to use a CBDC unit more than once without updating the common ledger of CBDC.
  • But it can be mitigated to a larger extent by technical solutions and appropriate business rules including monetary limits on offline transactions.
