Understanding Central Bank Digital Currency: Implications and Benefits for India

Introduction

In the 1980s, American Nobel Laureate James Tobin proposed the creation of Federal Reserve Banks in the United States, advocating for a public medium that offers the convenience of deposits and the safety of currency. This concept was revisited in a keynote address by Shri T Rabi Sankar, Deputy Governor of the Reserve Bank of India (RBI), on July 22, 2021, during a webinar organized by the Vidhi Centre for Legal Policy in New Delhi. The address, which is provided below for reference, seeks to clarify the implications and details surrounding digital currency.

The objective of this analysis is to simplify the understanding of digital currency and its future impact on monetary markets. For this, various sources will be referenced to ensure accuracy and a clear comprehension of the subject. The RBI's Deputy Governors are recognized as some of the most knowledgeable central bank executives globally, reflecting the credibility of the information presented.

The Significance of Digital Currency

The evolution of digital currency has generated considerable interest, especially as it inherits the benefits of private virtual currencies while mitigating their social and economic drawbacks. The contemporary dialogue surrounding digital currency includes discussions on its unique appeal, encompassing private digital currencies and the digitized versions of transactions like bonds and communications.

Central bank digital currency (CBDC) retains the valid advantages of private currencies without the adverse effects associated with them. To understand CBDC thoroughly, it is essential to address the fundamental question: What is currency?

Understanding Currency

As societies transitioned from hunting and gathering, their material needs surged, leading to the emergence of the barter system. However, barter could not meet the rising demand for convenience, resulting in the adoption of gold and silver coins. Historical evidence, such as clay tablets from Mesopotamia and paper currency from 11th-century China, illustrates the evolution of money, which manifested as either commodities with intrinsic value or as debt instruments.

When money lacks intrinsic value, it must represent a claim on valuable commodities or other debt instruments. Thus, currency is fundamentally a debt instrument recognized by its issuer. The statement from the keynote address emphasizes this point: "It offered stability to the currency due to the credit rating of a sovereign which was far ahead of an individual. Secondly, paper currency involves seigniorage – the difference between the intrinsic value and the representative value, which should accrue to the Government for public spending."

From this, we define currency as a form of money issued exclusively by a sovereign or a central bank. It functions as both a liability of the issuing central bank (and sovereign) and an asset for the public.

What Is Central Bank Digital Currency?

According to the Deputy Governor, "A CBDC is the legal tender issued by a central bank in digital form. It is the same as a fiat currency and is exchangeable one-to-one with fiat currency, differing only in form."

The distinction between CBDCs and private digital currencies must be clarified. Unlike private digital currencies, which lack issuer transparency and legitimacy, CBDCs are sovereign currencies represented digitally and are recorded as liabilities on a central bank's balance sheet.

Justifying the Need for CBDC

The growing interest in CBDCs is evident from a 2021 survey conducted by the Bank for International Settlements (BIS), where 86% of central banks reported researching CBDC potential, 60% engaged in technology experimentation, and 14% initiated pilot projects. The motivations for adopting CBDCs include:

Aiming to counteract declining paper currency usage, as seen in Sweden.
Enhancing the efficiency of currency issuance in cash-prevalent jurisdictions such as Denmark and Japan.
Meeting public demand for digital currencies in light of the rising use of private virtual currencies.

The emergence of private digital currencies from unidentified origins has prompted global central banks to consider legal and regulated digital currency options.

The Potential Benefits of CBDC

For exporters, receiving payments in digital currency eliminates intermediaries and associated risks. Additionally, the swift nature of CBDC transactions leads to final payments not subject to dispute.

India has experienced significant growth in digital payment innovations, achieving an impressive compound annual growth rate (CAGR) of 55% over the past five years. The Unified Payments Interface (UPI) exemplifies the country's capabilities, allowing transactions of as little as one rupee. This success raises the question: Should India consider CBDC implementation?

Insights from Payment Surveys

A pilot survey conducted on retail payment preferences across six cities revealed that cash remains the primary choice for transactions under ₹500. However, preference shifts toward digital methods for transactions between ₹2,000 and ₹5,000 and beyond, reflecting a growing acceptance of digital currency.

The Entry of Private Digital Currencies

The proliferation of private digital currencies, despite their lack of sovereign backing, highlights the necessity of a central bank digital currency. As Christine Lagarde, President of the European Central Bank, stated, "Central banks have a duty to safeguard people's trust in our money."

The rationale for CBDCs is evident — they are essential not only for enhancing payment systems but also for protecting citizens against volatile private virtual currencies.

Addressing the Anticipated Challenges

Questions surrounding the necessity for CBDC in India persist. Key considerations include its impact on the existing banking system, and potential risks associated with its rollout. The introduction of CBDC may alter the dynamics of bank deposits, leading to speculation about the need for bank credit.

As we envision a future with both CBDCs and traditional bank deposits, it is anticipated that interest-bearing bank deposits will remain preferable over time. Moreover, managing the demand for CBDC in conjunction with traditional banking could maintain market balance.

Technological Preparedness and Regulatory Framework

To effectively introduce digital currency on a population level, considerations such as internet accessibility, telecommunication infrastructure, and equitable distribution must be addressed.

The RBI is currently prioritizing a phased implementation of CBDCs and is engaged in exploring potential use cases with the least disruption. Key aspects under examination include:

The purpose and scope of CBDCs: Retail versus wholesale payments.
The choice of underlying technology: Distributed ledger versus centralized systems.
Validation mechanisms: Token-based or account-based.
Distribution methods: Direct issuance by RBI versus through commercial banks.
The extent of anonymity and privacy.

Legislative aspects impacted by CBDCs encompass several acts, including the Reserve Bank of India Act, 1934, the Coinage Act, 2011, and the Information Technology Act, 2000.

Conclusion

The introduction of CBDCs offers notable advantages, such as reducing dependency on cash, fostering greater efficiency, and minimizing settlement risks. Potential benefits must be weighed against associated risks, as the RBI aims to enhance India's leadership position in payment systems.

As India advances in digital currency initiatives supported by robust technological infrastructure, it is plausible to anticipate a dynamic transition toward a centralized digital currency framework, propelling the nation into a leading role in the global digital economy.
