E-Rupee: Exploring India’s Digital Currency Revolution


In March 2023, the Reserve Bank of India (RBI) made headlines with the revelation that the E-rupee, the digital representation of India’s legal tender, had a total circulation worth ₹16.39 crore. This groundbreaking development signifies a significant step in the digitization of currency in India. In this comprehensive blog, we will delve into the details of the E-rupee, its circulation, potential impact on the Indian economy, and the broader implications of this digital transformation. Join us on this journey as we explore the exciting world of India’s E-rupee.

Understanding the E-Rupee:

The E-rupee is the digital counterpart of the Indian rupee, akin to physical currency but in electronic form. It represents a fundamental shift in the way financial transactions are conducted, offering a more convenient and efficient means of exchange in an increasingly digital world.

Breaking Down the Circulation of E-rupee:

As of March 2023, the RBI reported a total E-rupee circulation of ₹16.39 crore. This impressive figure can be further categorized into two main segments: wholesale CBDC (Central Bank Digital Currency) and retail CBDC.

Wholesale CBDC:

This segment accounted for ₹10.69 crore of the total circulation. Wholesale CBDC plays a pivotal role in facilitating the settlement of secondary market transactions in government securities. This component was introduced in November 2022, marking a significant milestone in the journey towards a digital economy.

Wholesale CBDC, also known as CBDC (W) or e₹-W, serves as the backbone of large-scale financial transactions. It enhances efficiency, reduces settlement times, and minimizes the risk associated with traditional settlement processes. This development holds great promise for the financial sector, particularly in the realm of government securities trading.

With the wholesale CBDC system in place, financial institutions and government entities can conduct high-value transactions with ease and security. This not only streamlines the financial ecosystem but also reduces the reliance on physical currency, paving the way for a more sustainable and efficient economy.

Retail CBDC:

The retail CBDC component made up ₹5.70 crore of the E-rupee circulation. Launched in December 2022, the retail CBDC initially involved eight public and private sector banks. Over time, it has expanded its reach to include more banks and merchants, becoming interoperable with UPI (Unified Payments Interface) QR codes.

Retail CBDC, also known as CBDC (R) or e₹-R, is designed to enhance the ease of everyday financial transactions for consumers and businesses alike. It allows for quick and secure payments, reducing the reliance on physical cash and checks.

The introduction of retail CBDC has transformed the way individuals and businesses conduct transactions. Its integration with UPI QR codes has made it accessible to a broader audience, further accelerating the adoption of digital currency in India. This move aligns with the global trend toward reducing cash usage and promoting digital financial inclusion.

Most Circulated Denominations of E-rupee:

Among the various denominations of E-rupee, the ₹500 CBDC notes took the lead with a circulation of ₹2.71 crore. Following closely behind were the ₹200 notes, accounting for 1.16% of the total circulation. The remaining denominations, ranging from 50 paise to ₹100, constituted less than 1% of the circulation, each with varying levels of usage.

The prominence of the ₹500 CBDC notes highlights the role of E-rupee in larger-value transactions. These notes are favored for significant purchases, further emphasizing the versatility of digital currency. Whether it’s a high-value purchase, a business transaction, or an investment, the E-rupee offers a seamless and secure means of conducting financial activities.

The Evolution of E-Rupee

The journey of the E-rupee began with a pilot project that laid the foundation for its subsequent expansion and adoption.

Wholesale CBDC Pilot (CBDC (W) or e₹-W)

Introduced in November 2022, the wholesale CBDC pilot was initially limited to the settlement of secondary market transactions in government securities. This marked the RBI’s initial foray into the world of digital currency. The successful launch of this pilot laid the groundwork for more extensive use cases in the future.

The wholesale CBDC pilot is a testament to the RBI’s commitment to modernizing India’s financial infrastructure. It not only simplifies the settlement of government securities but also positions India as a leader in the adoption of digital currency for financial markets. This strategic move aligns with global efforts to digitize financial systems and reduce the reliance on traditional paper-based processes.

Retail CBDC Pilot (CBDC (R) or e₹-R)

Launched in December 2022 within a closed user group comprising participating customers, banks, and merchants, the retail CBDC pilot quickly gained traction. The initial participation of eight public and private sector banks was a significant milestone. Over time, thi s retail E-rupee has expanded its reach to more banks and achieved interoperability with UPI QR codes.

The retail CBDC pilot signifies a shift in how everyday transactions are conducted in India. It empowers consumers and businesses with a digital alternative to physical cash. This transition not only enhances convenience but also reduces the costs associated with handling and transporting physical currency. It’s a step towards a more efficient and inclusive financial ecosystem.

The Path to UPI Interoperability:

One of the pivotal developments in the E-rupee’s journey is its interoperability with UPI, a widely used payment system in India. The RBI Deputy Governor revealed that 13 banks were involved in the retail CBDC pilot for UPI interoperability. However, extending this feature to the remaining top 20–25 banks would take some more time.

The integration of E-rupee with UPI opens up a new dimension in digital transactions. It seamlessly bridges the gap between digital currency and the existing payment infrastructure. Consumers can make E-rupee payments using familiar UPI QR codes, making the transition to digital currency even smoother.

The move toward UPI interoperability reflects the RBI’s commitment to enhancing financial inclusion. By ensuring that E-rupee is accessible to a wide range of financial institutions, the central bank is taking steps to bring the benefits of digital currency to every corner of India. This inclusivity is vital in ensuring that all segments of society can participate in the digital economy.

Future Prospects and Expansion of E-rupee:

With UPI interoperability successfully implemented, the focus now shifts to increasing the volume of E-rupee transactions. Currently, the daily volume of E-rupee transactions stands at around 15,000. The RBI’s goal is to elevate this number to one million (10 lakh) transactions, signifying the central bank’s commitment to driving the adoption of digital currency.

Scaling up transactions to one million per day represents a significant growth opportunity for E-rupee. It requires a multi-pronged approach that involves raising awareness, building trust, and expanding the network of institutions and businesses that accept E-rupee payments.

The benefits of achieving this target are far-reaching. Firstly, it reduces the reliance on physical currency, which can be costly to produce and manage. Secondly, it enhances transparency in financial transactions, making it easier to track and combat illicit activities such as money laundering and tax evasion. Lastly, it positions India as a leader in the global digital currency landscape, opening up opportunities for cross-border transactions and collaborations.

Impact on Financial Inclusion:

One of the notable aspects of the E-rupee’s journey is its potential to boost financial inclusion in India. The digitization of currency has the power to reach underserved and remote areas, making financial services accessible to populations that were previously excluded from the formal financial system.

In rural India, where traditional banking infrastructure may be limited, digital currency can fill a crucial gap. It enables people to make payments, receive salaries, and access financial services using mobile phones, even in areas with limited access to physical bank branches.

Moreover, the interoperability of E-rupee with UPI is a game-changer in this regard. UPI has already gained significant popularity in India for its simplicity and accessibility. Now, with E-rupee integrated into the UPI ecosystem, individuals in both urban and rural areas can use digital currency for a wide range of transactions.

Financial inclusion also extends to small and medium-sized enterprises (SMEs). These businesses are the backbone of India’s economy, and their ability to access digital financial services can lead to increased efficiency and growth. E-rupee’s ease of use and reduced transaction costs can be a boon for SMEs, enabling them to participate more actively in the formal economy.

Security and Regulatory Framework for E-rupee:

As the adoption of digital currency grows, so does the importance of security and a robust regulatory framework. The RBI has been proactive in addressing these concerns.

Security measures are a top priority to protect consumers and the financial system from cyber threats. Secure blockchain technology powers E-rupee transactions, ensuring transparency and immutability. Blockchain guarantees that it records transactions unalterably, providing a high level of security and trust.

Furthermore, the RBI has established a regulatory framework to govern the issuance and use of E-rupee. This framework includes measures to combat fraud, ensure compliance with anti-money laundering (AML) and know-your-customer (KYC) regulations, and safeguard the integrity of the financial system.

The regulatory framework also addresses issues related to consumer protection. It sets guidelines for dispute resolution, fraud prevention, and the responsibility of financial institutions in safeguarding customer funds. These measures are essential to build trust in digital currency and protect consumers from potential risks.

International Collaboration:

The journey of E-rupee doesn’t stop at India’s borders. The international dimension of digital currency is gaining momentum, and India is actively exploring opportunities for collaboration and engagement with other countries.

Cross-border transactions using digital currency have the potential to revolutionize international trade and finance. They can reduce the time and costs associated with traditional cross-border payments, making it easier for businesses to engage in global commerce.

India’s participation in international discussions and collaborations related to digital currency aligns with its aspirations to be a global leader in financial innovation. As digital currency becomes increasingly integrated into the global financial system, India is positioning itself to benefit from and contribute to this evolving landscape.

Challenges and Concerns:

While the journey of E-rupee is marked by promise and potential, it is not without challenges and concerns.

One of the foremost concerns is cybersecurity. The digital realm is fraught with threats, including hacking, phishing, and malware attacks. Protecting the integrity of the E-rupee system is of paramount importance. The RBI and financial institutions must continually invest in cybersecurity measures to safeguard the digital currency ecosystem.

Another concern is the digital divide. While digital currency offers numerous advantages, it may exclude those who do not have access to the internet or digital devices. Bridging this gap is essential to ensure that all segments of society can benefit from E-rupee.

Additionally, the rapid adoption of digital currency may raise issues related to data privacy and surveillance. Striking the right balance between security and privacy is a challenge that regulators and policymakers must grapple with.


The introduction and rapid expansion of India’s E-rupee represent a significant leap towards a digital future. The E-rupee comprises wholesale and retail components, offers UPI interoperability, and targets ambitious growth, reshaping Indian transactions. As the nation embraces the digital currency revolution, the E-rupee symbolizes financial progress and innovation.

In a world where the digital economy is becoming increasingly dominant, India’s E-rupee serves as a beacon of modernization. It offers convenience, efficiency, and inclusivity, making financial transactions more accessible to all. While we observe the ongoing transformation of India’s digital currency landscape, it becomes evident that the E-rupee represents more than just a currency—it serves as a driving force in reshaping our attitudes and practices regarding money in the digital era.

As India progresses toward a cashless future, the E-rupee will shape its financial landscape significantly. This success reflects the RBI’s vision and the adaptability of Indian society. In the coming years, we anticipate the E-rupee’s integration into daily life, from local shop transactions to global financial dealings. Its influence will extend far and wide.

The journey has just begun, and the destination is a cashless, digitally empowered India. Stay tuned as we continue to explore the limitless potential of the E-rupee in transforming India’s financial ecosystem, and witness firsthand the digital currency revolution unfold before our eyes.
