Abstract 

This paper examines how Central Bank Digital Currencies (CBDCs) are being developed today, 
looking at the reasons central banks are interested in them and the challenges involved in making 
them a reality. By analyzing case studies from around the world and recent academic insights, the 
paper identifies key economic, technological, and policy-driven factors encouraging CBDC 
adoption. It highlights the promise CBDCs have for improving monetary policy effectiveness, 
making payment systems faster and cheaper, and increasing financial inclusion. At the same time, 
it acknowledges significant risks, such as the possibility of weakening traditional banks, concerns 
about user privacy, and threats from cyberattacks. Through comparing different global CBDC 
projects, such as China’s digital yuan (e-CNY) and the Bahamas’ Sand Dollar, the paper 
demonstrates how each country's unique priorities and technological readiness shape their 
approaches to CBDCs. It underscores the need for clear regulations, seamless integration between 
systems, and cooperation across borders to ensure CBDCs are safe and effective. The paper also 
provides recommendations for future policy-making and research to support well-informed 
decisions in this fast-changing area. 

 
Keywords: Central bank digital currency (CBDC), Digital payment systems, Financial inclusion, Financial stability, Monetary policy,

1. Introduction 

The development of digital currencies has attracted considerable interest in recent years, largely driven by 
rapid technological progress and shifts in the global financial landscape. Digital currencies are generally divided 
into cryptocurrencies and stablecoins, with stablecoins specifically designed to maintain price stability by linking 
their value to traditional currencies or other assets (Dionysopoulos et al., 2024). Although stablecoins aim to offer a 
more stable alternative for everyday transactions, there remain ongoing concerns about their regulation and the 
adequacy of their asset reserves. 

Central Bank Digital Currencies (CBDCs) have become relevant to modern central banking for various 
economic and financial reasons. A key factor is the declining use of cash in many countries, prompting central 
banks to explore digital forms of currency to ensure continued public access to secure, risk-free money. Moreover, 
the rapid rise of private digital payment solutions, including cryptocurrencies and fintech innovations, has sparked 
concerns about potential threats to monetary sovereignty and financial stability (Genc & Takagi, 2024). CBDCs 
provide central banks with a way to maintain control over the payment infrastructure, ensure financial inclusion, 
and reduce reliance on private digital currencies (Di Iorio et al., 2024). 

An important aspect of CBDC adoption is their potential effect on monetary policy. By offering a digital 
alternative to cash and traditional bank deposits, CBDCs could significantly strengthen monetary policy 
effectiveness, giving central banks greater control over money supply and interest rates. They could also 
streamline cross-border payments, reducing costs and delays compared to existing financial networks (Kunaratskul 
et al., 2024). Despite these advantages, implementing CBDCs presents several notable challenges, such as the risk 
of weakening traditional banks, cybersecurity threats, and complex regulatory issues (Das et al., 2023). Widespread 
use of CBDCs might reduce bank deposits, potentially disrupting traditional banking operations and impacting 
banks' ability to provide credit. As digital instruments, CBDCs could become attractive targets for cyberattacks, 
requiring rigorous security protections to safeguard the financial system. Effective implementation also demands 
clear regulatory frameworks addressing privacy, data protection, and compliance with existing financial rules. 

This paper aims to investigate the main factors driving the development of CBDCs and evaluate their potential 
impacts on central banking and financial stability. It is organized into six sections. Following the Introduction, 
which outlines the background, relevance, and objectives of the study, Section 2 provides a conceptual overview of 
CBDCs, tracing their evolution and distinguishing them from cryptocurrencies and stablecoins. Section 3 explores 
the key motivations behind CBDC development, including monetary policy effectiveness, financial inclusion, and 
the preservation of monetary sovereignty. Section 4 examines global trends and policy approaches, presenting a

comparative analysis of CBDC strategies in selected countries. Section 5 discusses future perspectives and open 
questions, addressing unresolved policy, legal, and economic issues that require further research. Finally, Section 6 
concludes with a synthesis of key findings, policy recommendations, and directions for future research. 
 

2. Concept and Evolution of Central Bank Digital Currencies (CBDCs) 
Central Bank Digital Currencies (CBDCs) are digital forms of official currency issued and regulated by central 

banks. They provide a secure, government-supported alternative to physical cash and traditional electronic 
payment methods. Unlike decentralized cryptocurrencies, which operate independently of central authorities, 
CBDCs are fully integrated within existing financial systems and monetary policies, ensuring trust and regulatory 
oversight. Their main purpose is to modernize financial transactions, make payments more efficient, and support 
financial inclusion, particularly for populations with limited access to banking services (Iqbal et al., 2024). 

CBDCs have distinct characteristics that set them apart from other digital financial instruments. Since they are 
backed by central banks, CBDCs offer stability and function as legal tender, unlike cryptocurrencies which typically 
experience high volatility and lack intrinsic value (Singh & Yadav, 2024). Retail CBDCs are intended for general 
public use, facilitating everyday payments through digital wallets and bank accounts. Wholesale CBDCs, on the 
other hand, are designed for financial institutions to simplify and speed up interbank transactions. Additionally, 
CBDCs can include programmable features, enabling capabilities like smart contracts and automated payments, 
enhancing security and transparency in financial operations (Liu, 2024). 

Digital currencies have their roots in early electronic cash experiments from the 1990s, such as DigiCash and 
Mondex, which aimed to develop secure digital payment systems but did not achieve widespread adoption 
(Tommerdahl, 2025). The launch of Bitcoin in 2009 marked a significant turning point, motivating central banks to 
consider creating digital alternatives within their control (Liu, 2024). Growing popularity of cryptocurrencies and 
stablecoins, coupled with the global decline in cash use, further boosted interest in CBDCs (Soltaninejad et al., 
2024). According to research by Singh & Yadav (2024), more than 130 countries, representing over 98% of global 
GDP, are actively exploring CBDCs, with several already having operational systems. 
The table below outlines key milestones in the development of CBDCs:

CBDCs differ considerably from cryptocurrencies and other digital payment solutions in their structure, 

objectives, and regulatory frameworks (Tommerdahl, 2025). Table 2 contains a comparison of CBDCs, 
cryptocurrencies and stablecoins.

Unlike cryptocurrencies primarily used for speculation, CBDCs aim to be stable digital currencies directly 

backed by governments. Stablecoins, like USDT (Tether) and USDC, attempt to achieve price stability by pegging 
their value to traditional currencies or other assets. However, since stablecoins are issued by private entities, they 
carry risks related to issuer credibility and regulatory compliance, unlike CBDCs which benefit from explicit state 
backing (Pastor Sempere, 2025). 

The increasing momentum towards CBDC development represents a global shift toward digital financial 
infrastructure. Countries worldwide are evaluating CBDCs to improve payment efficiency, provide financial access 
to underserved populations, and strengthen monetary policy effectiveness. The COVID-19 pandemic emphasized 
the need for digital payment alternatives, accelerating CBDC research and testing. Nevertheless, introducing 
CBDCs involves managing challenges such as potential disruptions to traditional banking, cybersecurity threats, 
and regulatory complexities. Ultimately, the success of CBDCs will hinge on their ability to balance technological 
innovation with financial stability, ensuring broad acceptance and trust in the evolving digital economy. 
 

3. Motivations for Central Banks to Develop Digital Currencies 
The motivations behind developing Central Bank Digital Currencies vary considerably across different regions, 

shaped by economic, technological, and political factors. One major motivation for central banks is the potential to 
enhance the effectiveness of monetary policy. CBDCs offer central banks a more direct method to influence money 



Asian Business Research Journal, 2025, 10(9): 16-22

supply and interest rates compared to traditional monetary policy, which relies heavily on commercial banks and 
financial intermediaries. (Soltaninejad et al., 2024). 

Additionally, CBDCs can strengthen the resilience of the financial system by providing a government-backed 
alternative to private digital currencies. This is increasingly important with the rise of stablecoins—digital 
currencies pegged to fiat money—because they carry significant risks due to limited regulatory oversight and 
potential solvency issues (Conlon et al., 2024). Central banks see CBDCs as a secure and reliable option to mitigate 
the dependency on less regulated private digital assets. 

Another major motivation is the growing dominance of private digital currencies and stablecoins, such as 
Bitcoin, Monero, and Tether. These digital currencies operate beyond the control of central banks, posing 
significant risks to monetary sovereignty and financial stability (Chia, 2024). Countries facing high levels of 
currency substitution—where foreign currencies dominate local transactions—consider CBDCs crucial for 
maintaining monetary sovereignty. Issuing a state-backed digital currency can help these countries reduce reliance 
on foreign currencies and maintain control over their economic policies (Hilpert & Tokarski, 2024). 

CBDCs also offer significant potential to improve financial inclusion, providing digital financial services to 
populations without adequate access to traditional banking. Many people, particularly in developing countries, face 
barriers such as high costs, geographic isolation, or ineffective banking institutions. Accessible through mobile 
devices, CBDCs can serve as a low-cost, efficient financial inclusion solution (Ozili, 2024). By allowing individuals 
direct access to digital currency without requiring traditional bank accounts, CBDCs can decrease reliance on 
commercial banks and promote broader economic participation. Additionally, governments can use CBDCs to 
distribute welfare payments directly, reducing fraud, intermediaries, and transaction costs. 

Improving payment system efficiency is another immediate benefit of CBDCs. Traditional payment systems, 
especially for cross-border transactions, are often slow, expensive, and inefficient due to multiple intermediaries. 
CBDCs could streamline these processes by offering fast and affordable government-backed digital payments 
(Baltgailis et al., 2024). Integration with existing digital payment systems can facilitate seamless domestic and 
international transactions, benefiting consumers and businesses by significantly lowering costs and improving 
economic efficiency. 

CBDCs further support financial transparency, allowing regulators to monitor transactions in real-time and 
quickly detect suspicious activities. This feature aligns with global initiatives aimed at enhancing transparency and 
regulatory compliance. Nevertheless, privacy concerns are significant, as excessive oversight could discourage 
public adoption of CBDCs. 

Geopolitical factors also influence CBDC development. Countries recognize the strategic importance of digital 
currencies for maintaining economic independence. For instance, China has progressed significantly in developing 
its CBDC, while the European Union has taken a more cautious approach (Hilpert & Tokarski, 2024). CBDCs could 
potentially be employed in international trade to circumvent economic sanctions, emphasizing their geopolitical 
importance beyond domestic finance. 
 

4. Global Trends and Policy Approaches 
While central banks worldwide generally share similar goals when introducing Central Bank Digital 

Currencies (CBDCs)—such as improving payment systems, boosting financial inclusion, and safeguarding 
monetary control—the actual implementation strategies differ significantly across countries. These variations 
result from unique combinations of technological capabilities, financial structures, legal systems, and policy goals, 
reflecting each nation's specific economic and institutional contexts. 

China’s digital currency, the e-CNY, is among the most advanced CBDC projects globally. The People's Bank 
of China (PBoC) employs a two-tier distribution system, where commercial banks act as intermediaries, managing 
the issuance and circulation of the currency. This approach ensures a balance between state control and private-
sector participation (Wang, 2022). A major goal of the e-CNY is to reduce reliance on private digital payment 
services like Alipay and WeChat Pay, thereby strengthening the central bank’s influence in the domestic financial 
system. Additionally, the e-CNY aims to enhance the efficiency of cross-border transactions, aligning with China’s 
broader geopolitical goals, such as the Belt and Road Initiative. It also features managed anonymity, allowing the 
government regulatory oversight while preserving some transactional privacy. By September 2024, the e-CNY 
recorded a significant increase in usage, with the total value of transactions reaching approximately 7 trillion yuan 
(around 987 billion USD). This growth indicates the rising acceptance of the digital currency among Chinese 
citizens and businesses (Reuters, 2024). 

In Europe, the European Central Bank (ECB) has adopted a structured and cautious approach to developing the 
digital euro. Unlike China's approach, the digital euro is designed to complement existing financial services rather 
than replace them. The ECB prioritizes maintaining financial stability, protecting against cyber threats, and 
ensuring data privacy. It also seeks to avoid undermining traditional banks by preventing widespread shifts from 
bank deposits to digital currency holdings Ceylan, 2024; Mayer, 2024). The recent research (2024) by OMFIF’s 
Digital Monetary Institute reveals that enthusiasm among European central banks for CBDCs is declining. Their 
study shows that only 13% of central bankers see CBDCs as a promising solution for cross-border payments, a 
sharp decrease from 31% the previous year. (Chambers, 2025). 

The United States Federal Reserve is carefully evaluating the feasibility and implications of a digital dollar, 
considering both retail (public use) and wholesale (bank-to-bank) applications. Initiatives like Project Hamilton, a 
joint effort between the Boston Federal Reserve and the Massachusetts Institute of Technology (MIT), are focused 
on technical factors such as transaction speed and scalability (He et al., 2022; Koparan, 2025). However, in his 
second presidency, Donald Trump has taken a firm stance against the development of a central bank digital 
currency (CBDC) in the United States, emphasizing concerns over financial surveillance and loss of individual 
privacy. Through Executive Order 14178, he officially prohibited any federal agency from issuing or promoting a 
CBDC. 

Smaller economies and emerging markets demonstrate diverse approaches. The Bahamas' Sand Dollar, 
launched in 2020, was one of the first operational retail CBDCs globally. It addresses unique geographical

challenges, integrating mobile wallet technology with offline transaction capabilities to support financial inclusion 
in remote areas (Soderberg et al., 2022). This case highlights how specific local needs can shape CBDC designs. 
Despite its pioneering status, adoption has been gradual, prompting recent initiatives to enhance its integration 
and usage. As of early 2024, approximately B$2.1 million in Sand Dollars are in circulation, accounting for less 
than 0.5% of the total currency supply. While around 120,000 digital wallets have been registered, this number 
includes both residents and tourists, reflecting the Bahamas' significant visitor numbers (Ledger Insights, 2024). 

Nigeria’s eNaira provides another perspective, utilizing a hybrid distribution model combining central bank 
issuance with commercial bank distribution. However, its rollout faced significant hurdles, including issues related 
to public trust, limited compatibility with existing digital services, and low digital literacy among users. These 
challenges underline the importance of public readiness and acceptance, beyond just technological implementation 

(Ceylan, 2024). As of October 2024, the total value of eNaira transactions reached approximately ₦18.32 billion, 
marking a 57% increase compared to the previous year. Despite this growth, overall adoption remains modest, with 
less than 0.5% of Nigerians utilizing the eNaira within a year of its launch (Vanguard Nigeria, 2025). 

Jamaica's JAM-DEX takes an innovative approach, leveraging blockchain technology and open-source 
platforms. The Jamaican government encourages private-sector participation in developing digital wallets and 
additional financial services. Public policy initiatives, including incentives for early adoption, aim to accelerate 
public acceptance and usage, demonstrating how government support combined with accessible technology can 
drive rapid behavioral change (Mu & Mu, 2022).

Globally, there is a clear distinction between countries focusing on retail Central Bank Digital Currencies 

(CBDCs) intended for everyday public use, and those prioritizing wholesale CBDCs for institutional or interbank 
transactions. Retail models have attracted significant political attention due to their potential to boost financial 
inclusion and modernize domestic payment systems. Meanwhile, several advanced economies are actively exploring 
wholesale CBDCs, particularly for cross-border and interbank settlements. For example, the mBridge project—
jointly led by the Bank for International Settlements (BIS) Innovation Hub with participation from China, 
Thailand, the UAE, and Hong Kong—focuses on enhancing cross-border payments and real-time settlements 
between central banks. These initiatives aim to reduce dependence on traditional correspondent banking networks 
and lessen the dominance of major global currencies in international payments (Mayer, 2024). 

The choice of technology also reveals significant differences. Countries like China and The Bahamas prefer 
centralized database systems, which provide easier management and regulatory compliance. In contrast, other 
regions prioritize distributed ledger technologies (DLT), favoring transparency, resilience, and interoperability. 
Notable projects such as Jamaica’s JAM-DEX, mBridge, and France’s Project Jura use blockchain-based DLT 
systems, reflecting a trend towards decentralized solutions (Lee et al., 2023). 

International institutions such as the International Monetary Fund (IMF) and the Bank for International 
Settlements (BIS) increasingly influence the standardization of CBDC practices, particularly among smaller 
economies. The IMF’s Virtual Handbook on CBDCs provides structured guidelines on evaluating readiness, 
covering legal, technological, and operational dimensions (IMF, 2024). Meanwhile, the BIS supports experimental 
initiatives focused on interoperability, security, and liquidity management across countries (Soderberg et al., 2022). 

Overall, although CBDCs represent a common goal among central banks to modernize financial systems for 
the digital era, their actual implementation follows diverse paths. These variations reflect not only differing 
national capabilities and policy goals but also deeper societal values around privacy, control, efficiency, and 
inclusion. Understanding these differences is crucial for shaping globally compatible, resilient, and flexible digital 
currency systems. 
 

5. Future Perspectives and Open Questions 
CBDCs represent a major step forward in the evolution of money. Many countries are already experimenting 

with or piloting CBDCs, but their long-term effects remain uncertain, raising important questions for researchers 
and policymakers about monetary policy, financial stability, and international finance. 

One critical area impacted by CBDCs is monetary policy. Introducing CBDCs could significantly change how 
money is created, distributed, and controlled. For instance, central banks could have real-time insights into money 
flows, allowing them to apply monetary tools with greater precision and effectiveness. This capability might help 
better manage inflation or deflation risks. Yet, this advantage comes with significant uncertainty. If CBDCs gain 
popularity, particularly if they pay interest, people might shift funds away from commercial banks to CBDC 
accounts. This could reduce banks' ability to create credit, fundamentally altering the banking system and giving 
central banks an outsized role that they might not be prepared to handle. Policymakers need to consider carefully 
how to maintain the essential functions of banks without restricting credit availability or overwhelming central 
banks. 

CBDCs might also affect monetary policy by changing how quickly money moves through the economy and by 
improving liquidity management. For example, China's digital yuan (e-CNY) has shown potential to speed up 
money circulation and enhance control over central bank reserves. CBDCs could also improve how effectively 
central bank interest rate changes influence the broader economy, especially if the digital currencies earn interest. 
However, the specific design—such as limits on holdings or whether CBDCs pay interest—will greatly influence 



Asian Business Research Journal, 2025, 10(9): 16-22

this effect. Key concerns remain around managing currency volatility and ensuring that monetary policy remains 
effective if traditional banking roles are diminished. 

Internationally, CBDCs could revolutionize cross-border transactions by tackling inefficiencies like slow 
processing times, high costs, and lack of transparency. Distributed ledger technology (DLT)-based CBDCs might 
allow almost instant peer-to-peer transactions internationally, significantly reducing costs by cutting out 
intermediaries. Despite these benefits, the lack of common legal and technical standards among different countries 
presents major challenges. Additionally, if a large economy’s CBDC becomes dominant globally, it could 
undermine monetary sovereignty in smaller or developing countries. 

Regulatory challenges also persist. The global spread of CBDCs is likely to be uneven, creating fragmented 
standards and increasing risks like regulatory arbitrage, which can compromise financial stability, capital controls, 
and anti-money laundering (AML) measures. Policymakers must decide whether to establish international 
standards through global institutions like the IMF or Bank for International Settlements, or whether regional 
alliances with shared frameworks are more practical. 

CBDCs further raise foundational legal and ethical questions, particularly regarding privacy and traceability. 
While programmable CBDCs could effectively combat money laundering or terrorism financing by allowing 
traceability, they might also infringe on privacy rights or enable surveillance if mismanaged. Additionally, there is 
uncertainty about how CBDCs should be legally categorized internationally—are they digital cash, electronic 
money, or a completely new type of asset? 

The programmability of CBDCs introduces additional ethical dilemmas. For instance, currencies could be 
programmed to expire, restrict certain purchases, or fluctuate in value based on their use. While these features 
could be beneficial for targeted economic stimulus, they also risk misuse or overly intrusive controls by authorities. 
Determining the appropriate governance model for programmable money remains an open question. 

Another key concern is the potential impact of CBDCs during financial crises. If people view CBDCs as safer 
than bank deposits, they might quickly withdraw funds from commercial banks in stressful times, leading to 
accelerated bank runs due to the instantaneous nature of digital transactions. Although measures like transaction 
limits or withdrawal fees could mitigate this, their effectiveness is still unproven. 

CBDCs might also blur the boundaries between monetary and fiscal policy. For example, direct distribution of 
CBDCs to households during economic crises could stabilize incomes but raises questions about central banks 
encroaching on government roles. This could threaten central bank independence, prompting the need for updated 
legal frameworks and clear accountability standards. 

Given these complexities, CBDC development demands extensive interdisciplinary research covering 
macroeconomics, legal frameworks, cybersecurity, and ethical considerations. Policymakers must thoughtfully 
evaluate not just the technical designs, but also the broader implications for democracy, national sovereignty, and 
global cooperation.

In short, CBDCs could significantly transform our financial systems, but they come with major challenges. 

Success won't just depend on technological advancements—it also requires careful governance, international 
cooperation, and smart regulation. Future research needs to tackle these tough issues head-on to ensure that 
introducing CBDCs strengthens rather than disrupts our monetary and financial stability. 
 

6. Conclusion 
This paper explores how Central Bank Digital Currencies (CBDCs) have been developing globally, examining 

their motivations, design challenges, and the strategies being adopted worldwide. It provides a thorough look at 
contemporary trends shaping digital monetary innovation. The findings suggest that CBDCs offer significant 
potential benefits, such as improving the effectiveness of monetary policy, increasing financial inclusion, and 
enhancing the efficiency of cross-border payments. However, achieving these benefits requires careful consideration 
of technological, legal, economic, and geopolitical factors.

One important conclusion from this research is that there's no universal approach to CBDCs; each country's 
design and implementation must align with its unique institutional and economic conditions. Additionally, CBDCs 
have the potential to significantly alter the financial landscape by transforming traditional banking structures. This 
raises critical questions about the future roles of central banks, the process of money creation, and financial 
intermediation. Key technological decisions—like choosing between centralized databases or distributed ledger 
technologies and opting for token-based or account-based systems—greatly impact issues such as privacy, system 
resilience, and interoperability. 
The study provides several policy recommendations: 

• Developing clear legal and regulatory frameworks to ensure CBDC systems remain transparent, secure, 
and interoperable. 

• Designing CBDCs to support existing financial intermediaries, preventing disruptions such as 
disintermediation and potential credit contractions. 

• Establishing international standards and encouraging cross-border cooperation to prevent market 
fragmentation and ensure global financial stability. 

• Implementing layered privacy and identity protocols that achieve a balance between user privacy and 
regulatory requirements. 

This research contributes to the expanding discussion on CBDCs by bringing together various perspectives on 
digital currency evolution within the context of central banking. It emphasizes a comprehensive approach that 
integrates macroeconomic considerations, technological design, and governance structures. 
Looking forward, several areas require further research: 

• Empirical studies investigating how CBDCs influence monetary policy mechanisms and their broader 
macroeconomic effects. 

• Legal research exploring the cross-border legal status of CBDCs and their integration into existing 
financial regulations. 

• Interdisciplinary analyses addressing privacy, ethical considerations, and programmability to respond to 
societal concerns regarding surveillance and autonomy in digital finance. 

• Developing simulations and stress-testing models to assess CBDC performance under crisis scenarios, 
including digital bank runs and geopolitical tensions. 

Ultimately, while CBDCs hold transformative potential to modernize public monetary systems for a digital future, 
their success depends heavily on how effectively central banks, governments, and international organizations 
manage the delicate balance between innovation, stability, and national sovereignty.
