Digital currencies are redefining how the world perceives and transacts with money, signaling a potential shift toward a fully cashless economy. With the rise of cryptocurrencies like Bitcoin and Ethereum, global central banks have begun exploring the possibilities of a regulated digital currency, known as the Central Bank Digital Currency (CBDC). While several nations are in the research and development phase, countries like China have already entered pilot testing.
Digital currency carries all the essential functions of traditional cash—minus the physical form. While physical currency exists in both paper and electronic formats, digital currency is entirely electronic and can be accessed via smartphones or computers.
Users can make payments for goods or services using digital currency, just as they would with physical cash. For instance, instead of handing over cash or using a debit card, one can transfer digital currency to a retailer through a mobile phone—convenient, contactless, and efficient.
In the 1980s, equity stock and government bond trading relied on paper certificates. Today, this entire system operates digitally, offering greater speed, transparency, and efficiency. A similar transformation is anticipated with the adoption of digital currency, which can eliminate intermediaries and enable direct, peer-to-peer transactions that are faster, more accurate, and easily traceable.
Decentralized digital assets like Bitcoin and Ethereum already exist and are widely used, albeit outside the control of central banks. These currencies are powered by blockchain and distributed ledger technologies, allowing for secure and immutable transactions. Recognising this innovation, many governments are now considering creating regulated digital currencies, or CBDCs, to harness the benefits while maintaining regulatory oversight.
Digital currency is the umbrella term. Here’s how the subcategories differ:
Virtual Currency: A type of unregulated digital currency, typically controlled by its developers or a founding organisation. Examples include in-game currencies or loyalty points.
Cryptocurrency: A subset of virtual currency that uses cryptography for secure transactions and controlled supply. Cryptocurrencies can be decentralized (e.g., Bitcoin, Ethereum) or centralized (e.g., Facebook’s Diem).
A CBDC is a digital currency issued and regulated by a country’s central bank. Think of it as a cryptocurrency backed by the full trust and authority of a central bank like the RBI in India.
CBDC would function similarly to physical cash, with one key difference: once a CBDC transaction is completed, it cannot be reversed. This is because it uses blockchain, a secure and immutable ledger system. Unlike traditional payments that can be reversed due to technical errors or disputes, CBDC transactions are final.
Real-Time Payments: Domestic and international transactions can be completed instantly.
Cost Efficiency: Reduces reliance on intermediaries—especially useful in cross-border payments—leading to lower fees.
Round-the-Clock Access: Enables 24/7 financial transactions, irrespective of bank working hours.
Transparency & Traceability: Enhances accountability in financial flows, particularly in international transactions.
Financial Inclusion: Helps unbanked or underbanked populations to access digital financial services with minimal barriers.
Efficient Government Disbursements: Facilitates fast, targeted transfers during emergencies (e.g., pandemic relief), even to those without traditional banking access.
Learning Curve: Users need to understand how to open digital wallets and manage digital currency, which can be difficult for those with limited digital literacy.
Blockchain Cost: Cryptocurrencies like Bitcoin involve high energy consumption and transaction costs, making them less ideal for low-value transactions.
Price Volatility: Most digital currencies are highly volatile. However, CBDCs, backed by central banks, are expected to be more stable.
Implementation Complexity: Developing and deploying a nationwide CBDC is costly and time-intensive, requiring significant infrastructure overhaul and stakeholder alignment.
India remains a cash-dominated economy, particularly among SMEs and MSMEs, where many transactions are still made via cash or cheques. The anonymity of cash presents a challenge in introducing fully traceable digital currency.
Yet, India has consistently led in the adoption of digital infrastructure—from UPI to Aadhaar-enabled payments—making it well-positioned to pioneer CBDC deployment. The time is ripe for the Reserve Bank of India (RBI) to explore this opportunity and potentially lead the world in launching a fully functional CBDC.
