Money has taken many forms throughout history, from shells and silver to paper bills. Today, digitalization is reshaping finance, moving transactions from physical to virtual mediums. Governments worldwide are actively planning to phase out cash. According to the Bank for International Settlements (BIS), nearly 90% of central banks are now developing Central Bank Digital Currencies (CBDCs). Future generations may no longer understand the concept of "cash on delivery," as all transactions will simply be changes in numbers on a screen.
Understanding CBDCs: Legal Tender, Digital Currency, and Cryptocurrency
There is no universal definition for a CBDC, but as the name implies, it is a digital currency issued by a central bank. From a Taiwanese perspective, it would essentially be a digital version of the New Taiwan Dollar. It holds the same legal status as physical cash. Each unit of CBDC represents a liability of the central bank and carries its own unique digital identifier.
Among the three common payment methods—cash, bank deposits (transfers), and electronic payments—CBDCs fall into the cash category. In simple terms, since a CBDC is cash you can't physically touch, it operates by moving value from your digital wallet or account to the recipient's during a transaction. In this way, its functionality closely resembles that of existing electronic payment systems.
The concept of CBDCs is closely related to cryptocurrencies. Both are virtual currencies, and many CBDC projects utilize Distributed Ledger Technology (DLT), like blockchain, to ensure transaction privacy and security (though this is not a mandatory feature). The key difference lies in their foundation: a CBDC is sovereign legal tender, its value guaranteed by the central bank. Cryptocurrencies, however, operate purely on market mechanisms, with their highly volatile value dictated by market sentiment. For instance, the value of Dogecoin can skyrocket or plummet based on a single tweet from a celebrity like Elon Musk.
The Need for CBDCs in an Age of Digital Wallets
With the rise of FinTech, diverse electronic payment methods are already deeply integrated into modern life. In major Chinese cities, physical cash is nearly obsolete. Statista data shows digital payment penetration in China is as high as 86.2%, and most transactions in South Korea are conducted via credit card or electronic payment. So why are governments still pushing for CBDCs, which seem to duplicate existing market offerings?
Unifying a Fragmented Payment Landscape
Imagine yourself at a local food stall, ready to pay for your meal with LINE Pay, only for the staff to apologetically say, "Sorry, we only accept JKOPAY!" This awkward scenario highlights two issues: the closed-loop nature of private payment networks (where money is trapped within one ecosystem) and the significant consumer and merchant friction caused by a fractured payment market.
A CBDC could, in theory, solve this. As its essence is digital cash, refusing to accept it would likely be illegal (though enforcement can be challenging, as seen with Nigeria's e-Naira). Banks and payment service providers would be compelled to integrate with the CBDC network to facilitate its use. This would break down barriers between different payment platforms, effectively creating a unified, national payment rail.
Enhancing Monetary Policy and Financial Oversight
But what if the payment market is already unified? In China, WeChat Pay and Alipay dominate over 90% of the mobile payment market. In Sweden, the Swish app is virtually the only payment method. Here, a CBDC's role isn't to fix fragmentation but to allow for greater oversight and control.
Without a CBDC, transaction data resides in the databases of private companies. For governments investigating crimes like terrorist financing, money laundering, or fraud, tracing flows across multiple, proprietary systems is incredibly difficult. A CBDC moves these transactions onto a platform where the central bank has direct visibility, simplifying financial supervision and regulation.
Furthermore, with a widespread CBDC user base, monetary policy could be implemented with unprecedented speed and precision. Imagine the central bank wants to stimulate a sluggish economy. Today, this involves lowering the discount rate, influencing interbank rates, and waiting for commercial banks to lower their deposit rates, hoping people will spend instead of save. With a CBDC, the central bank could theoretically impose a negative interest rate directly on digital wallets, instantly incentivizing consumption and investment. For social welfare, emergency relief funds or stimulus vouchers could be distributed instantly and directly to citizens' CBDC accounts, eliminating the need for physical queues or paperwork.
Reducing Costs in Developing Economies
For nations with less developed financial infrastructure, CBDCs offer a leapfrog opportunity. The Harvard Business Review notes that the U.S. spends $600 billion annually and employs 1.2 million people to maintain its ATM and cash-handling infrastructure. Developing countries adopting CBDCs can bypass these costly, soon-to-be-obsolete physical systems, requiring only internet connectivity to build a modern digital financial ecosystem.
Global CBDC Adoption: Emerging Economies Lead the Way
Many emerging economies are already piloting or have launched CBDCs, with some achieving significant maturity.
The Bahamas: Ranked first in retail CBDC maturity by PwC, The Bahamas was the first country to launch a CBDC globally. Its "Sand Dollar," introduced in October 2020, allows citizens to make payments via a mobile app or a physical card. For a nation of 390,000 people spread across 700 islands, the Sand Dollar reduces transaction costs, increases payment efficiency and security, and helps combat financial crimes like money laundering and counterfeiting.
China: China's CBDC, the Digital Currency Electronic Payment (DCEP), is currently in advanced testing phases. It is being distributed via lotteries, giving residents in certain pilot zones 200 RMB to试用 (try out). The issuance model mirrors that of physical cash: the People's Bank of China issues DCEP to commercial banks, which then distribute it to the public. Given China's already advanced digital payment landscape, analysts speculate that DCEP's primary goal is to gain access to comprehensive consumption data, ensuring the government maintains economic oversight in the digital age.
Nigeria: Africa's largest economy launched the e-Naira in October 2021. However, its rollout has faced challenges. A significant drawback is that both sender and receiver need a bank account, yet only about half of Nigeria's population is banked. Furthermore, widespread public distrust in the government has hampered adoption.
Cambodia: Noting its high smartphone penetration but low bank account ownership (only 22% of those over 15 have an account), the National Bank of Cambodia partnered with Japanese blockchain startup Soramitsu. In October 2020, they launched "Bakong," an electronic payment platform. Although the country does not officially classify Bakong as a CBDC, its success in expanding financial inclusion in rural areas led PwC to rank Cambodia second globally in retail CBDC maturity.
Laos: Laos has recently begun its CBDC journey, signing a contract with Soramitsu in October to explore developing its own digital currency system.
The Developed World's CBDC Dilemma
Why is Soramitsu, a Japanese company, helping other nations build CBDCs while Japan itself lags in development? It's not that advanced economies are inactive—countries like South Korea and Sweden are in testing phases. However, the adoption of CBDCs presents unique and more significant challenges in developed nations.
Clashing with Established Interests
The features of a CBDC heavily overlap with those offered by private electronic payment platforms and commercial bank apps. From the financial industry's perspective, a state-backed CBDC could threaten their existing revenue streams. More critically, the central bank could potentially displace commercial banks in areas like small-scale lending. This risks accusations of government overreach into market mechanisms (as seen with suspicions that China's DCEP was used to curb the power of tech giants like Ant Group). The powerful political and commercial lobbying power of the financial sector can fundamentally delay or derail CBDC projects.
Furthermore, competitive capital markets drive fintech innovation by rewarding problem-solvers with high returns. A government-monopolized payment system could lack this competitive drive, potentially leading to less efficiency and slower innovation over time.
From a consumer standpoint, if people already have mature, convenient payment apps they are happy with—often supplemented by attractive shopping discounts and rewards—what is the incentive to switch to a government-issued CBDC?
Privacy and Security Concerns
The debate around privacy is paramount in democratic societies. Recent controversies in Taiwan over the privacy implications of the SMS-based contact tracing system highlight how citizens value their personal data. A CBDC would grant the government visibility into all user transactions. Any internal data leak or external hack would immediately escalate into a severe crisis. Implementing a CBDC requires an exceptionally high degree of public trust and robust technical security, necessitating rigorous legislative scrutiny. In most developed democracies, unless there is a overwhelming political incentive (e.g., a major security breach in a private payment platform causing public outrage), leaders may be reluctant to invest political capital in such a contentious project. 👉 Explore secure financial platforms
Will Taiwan Adopt a CBDC?
Taiwan began its CBDC testing in October 2020, but a full launch remains a distant prospect. Central Bank Governor Yang Chin-long has outlined three prerequisites for issuance: a solid legal framework, robust and mature technology, and support from a wide range of stakeholders.
Currently, the transaction processing capacity of Distributed Ledger Technology (DLT) is still unable to meet the demands of real-time, high-frequency, large-volume retail payments in Taiwan. Furthermore, although the Institute for Information Industry reported that mobile payment usage reached 60% in the second half of 2020, this penetration rate is still lower than that of the U.S. (82%) or China (86%). Taiwan's existing financial infrastructure is well-developed, cash usage remains strong, and platforms like LINE Pay and JKOPAY operate without major issues or significant financial crime events.
In summary, unless a CBDC offers features significantly superior to the current payment ecosystem, there is currently little incentive for either the public or policymakers in Taiwan to aggressively pursue a central bank digital currency. So, for the foreseeable future, we can all continue to enjoy the tangible feeling of holding physical cash.
Frequently Asked Questions
What exactly is a Central Bank Digital Currency (CBDC)?
A CBDC is a digital form of a country's sovereign currency, issued and backed by its central bank. It is legal tender, just like physical cash or coins, but exists only in electronic form. Each unit is a direct liability of the central bank, making it a secure and state-guaranteed means of payment.
How is a CBDC different from using LINE Pay or Alipay?
The key difference is the issuer and the nature of the money. LINE Pay and Alipay are private payment platforms that facilitate transactions using money from your linked bank account or credit card. The digital balance you see is a claim on a commercial bank. A CBDC would be digital cash issued directly by the central bank itself, making it a direct claim on the state, not a commercial intermediary.
What are the biggest advantages of a CBDC?
Major advantages include unifying fragmented payment markets, increasing financial inclusion for the unbanked, reducing the costs of printing and handling physical cash, and allowing for more precise and efficient implementation of monetary policy by central banks.
What are the main concerns surrounding CBDCs?
Primary concerns involve user privacy, as transactions could potentially be monitored by the state; cybersecurity risks of a centralized financial system; disruption to the traditional banking sector; and the challenge of achieving widespread public adoption when private alternatives already exist.
Could a CBDC completely replace physical cash?
While possible in the very long term, a complete replacement is unlikely in the near future. Many countries envision a dual system where CBDCs co-exist with physical cash to ensure everyone, including the elderly and those without digital access, can participate in the economy.
Which countries are leading in CBDC development?
Emerging economies like The Bahamas (Sand Dollar), Nigeria (e-Naira), and those in the Eastern Caribbean are among the first to fully launch retail CBDCs. Major economies like China (DCEP) are in advanced pilot stages, while many others, including the Eurozone and UK, are in research or development phases. 👉 Learn more about global financial trends
