Effect of Central Bank Digital Currencies (CBDCs) on the Global Financial System's Stability in Kenya

Introduction/Main Objectives: Central Bank Digital Currency (CBDC) is an electronic form of banknotes, but different from virtual currency or cryptocurrency which are not issued by the state, the CBDC issued and guaranteed by the central bank. The aim of this study is to investigate the impacts of CBDC on financial stability using a Vector Auto-regressive model. The endogenous variables in the VAR estimation contain the Central Bank Digital Currency Attention Index (CBDCA), composite stock price index, real exchange rate, and interest rate (BI7DRR). Background Problems: The presence of CBDC will change the objective of Bank Indonesia and influence the structure of the monetary policy, which is no longer focused on achieving a low and stable inflation rate but on achieving price stability. Novelty: Although CBDCs will be launched worldwide, there are a limited number of empirical studies that have analyzed their impact on financial stability, especially for the case study in Indonesia. In this paper, we also use the Vector Error Correction Model (VECM) model with stochastic volatility and Impulse Response Function to make a forecast and see the impacts of shocks on the financial variables. Research Methods: In this study, we used monthly time series data from January 2019 – January 2023. In order to find the correlation between CBDC and the financial market we used the Granger causality model and impulse response function analysis. Finding/Results: The results of this study prove that CBDC has a positive correlation with the real exchange rate, and financial markets such as stock or bond prices have a positive response to shocks in CBDC. Conclusion: In this study, we used monthly time series data from January 2019 – January 2023. We use empirical tests to examine the CBDC attention index in relation to index attention, exchange rates, interest rates and IHSG. Our empirical results show that in Granger causality there is no causal relationship between CBDC and other macroeconomic variables. whereas in the IRF analysis, the response to the CBDC shock tends to be stagnant, the FEVD results show short-term and long-term shock fluctuations in the CBDC and other variables. These results indicate that CBDC does not have a significant effect on the macroeconomic variables used as indicators of financial system stability, but on the contrary, people's attention to CBDC depends on the condition of the variables in the financial system. On the other hand, the development of CBDC depends on economic conditions. The uncertainty surrounding CBDC plays an important role in indicating that the introduction of CBDC brings significant changes to the economy.

The article studies the development of digital technologies in the global economy. It is determined that central bank digital currencies open up new opportunities in improving the efficiency of payment systems, reducing the cost of transactions in e-commerce, and increasing the level of financial inclusion. It has been found that the introduction of central bank digital currencies (CBDCs) may affect the deposit base of banks, potentially leading to increased costs and changes in their business models. However, beyond simple costs, a CBDC could also negatively impact the stability of the banking sector by expanding direct access to central bank liabilities, providing a public substitute for bank deposits, and altering bank business models. In general, competition for bank deposits from CBDCs may alter the architecture of the financial system, displacing the class of private debt, forcing banks to rely on alternative sources of financing, and possibly making the banking sector more vulnerable. The trilemma, which illustrates the fundamental principles of trade faced by central banks in managing CBDCs, has been analysed, demonstrating the complexity of balancing them in response to changes in financial technologies and economic expectations. According to Schilling, this trilemma asserts that a central bank managing a CBDC can achieve at most two of the following three objectives: financial stability, efficiency (optimal distribution of risks), or price stability. Choosing one of these objectives will inevitably lead to the sacrifice of at least one of the other two. It is concluded that digital central bank currencies are a new frontier in international monetary relations that can significantly change the way countries conduct cross-border trade, monetary policy, and financial cooperation. The impact of CBDCs on the financial sector can have far-reaching consequences, both positive and potentially negative. On the one hand, CBDCs promise to revolutionise the financial sector by improving the efficiency of payment systems, reducing transaction costs, and promoting greater financial inclusion. On the other hand, they can negatively impact the stability of the current financial system.

Central bank digital currencies (CBDCs) are been designed a ‘new normal’ for the world of finance in which payments (digital currency) can be made directly from one party to another without financial intermediaries regardless macroeconomic links. Digital currency has ushered the world of finance into uncharted waters as central banks and international institutions crumble to fine their feet’s in a fast moving stream of decentralised finance (DeFi) and global stablecoins. As central banks embark on the CBDCs journey, there are number of questions which must be address: What problems are CBDC’s expected to solve? How do current design thinking resolve these problems in Africa? Are there alternatives to CBDCs in Africa ? Broadly, CBDCs are expected to resolve inefficient and costly domestic and cross-border payments and settlement, ensure price stability and financial stability, retain monetary policy independence and digital de-dollarization. A qualitative descriptive design has been adopted in this study.Findings. Central bank digital currencies (CBDCs) well-designed in a new multilateral fair and just international monetary architecture has the potential to ensure price stability and financial stability in both advanced and developing economies in general, but more importantly would enable developing countries to regain some among of monetary policy independence. However, under the CBDCs design thinking within the framework of existing international monetary and financial architecture, no economy in Africa can withstand the powers of BigFintech, DeFi, global stablecoins and foreign sovereign digital currencies. This paper concludes that African countries must decide whether to cede their sovereign power to an independent monetary authority with single digital currency to manage under their control or cede their economic and financial destiny to unaccountable foreign BigFintech and/or foreign sovereign CBDCs in form of digital dollarization.

The article is devoted to the impact and role of digital currencies in ensuring the stability of the international financial system amid the digital transformation of the global economic space. It has been established that one of the key issues in contemporary financial regulation is the inherent dual nature of digital currencies, which manifests in their simultaneous function as instruments of financial innovation and as potential sources of instability in the absence of adequate monitoring and regulatory frameworks. Digital currencies (both private and state-issued, including CBDCs – central bank digital currencies) are gradually being integrated into the architecture of the international financial system and becoming a significant component thereof, with their role in ensuring stability encompassing several critical aspects. It has been substantiated that digital currencies contribute to the enhancement and optimisation of international settlements and payments, the reduction of transaction costs, and the increased transparency of financial operations, thereby mitigating systemic risks. By expanding access to financial services (financial inclusion) and strengthening monetary control by central banks over money circulation, digital currencies can reinforce the stability of financial markets, counteract currency and financial crises, and perform an anti-crisis function in preventing destabilising currency and financial factors. It is emphasised that the full realisation of the potential of digital currencies necessitates addressing new regulatory challenges, including cyber threats, destabilising capital flows between currencies, competition between state and private currencies, as well as risks of currency space fragmentation, which requires the establishment of coordinated regulatory frameworks. In conclusion, given appropriate regulatory frameworks, global coordination and the adaptation of financial infrastructure, digital currencies may become one of the key instruments for maintaining long- term stability and sustainable development within the international financial system. To fully realise their potential, it is necessary to account for emerging challenges – cyber threats, risks of capital flow destabilisation and currency competition – and to establish corresponding international regulatory frameworks. Digital currencies, under conditions of proper regulation and coordination, may serve as one of the principal instruments for sustaining stability and fostering sustainable development in the international financial system.

This study presents an in-depth investigation into cryptocurrencies and Central Bank digital currencies (CBDCs), focusing on implications for monetary policy and financial stability. An overview of CBDCs and cryptocurrency is evaluated by analysing their origins, significant characteristics, functionalities and roles in the economic ecosystem. A detailed assessment is carried out on the implication of cryptocurrency and CBDCs on monetary policy. The findings suggest that by facilitating decentralised and anonymous transactions, cryptocurrency deflates traditional monetary control and hence challenges the authority of central banks. In contrast, CBDCs are a better economic policy tool for central banks, thus probably raising policy effectiveness. Researchers analysed the implications of both virtual currencies on financial stability. They found that cryptocurrency poses a severe risk to financial systems due to its inherent volatility and instability. In contrast, they concluded that CBDCs offer a more viable alternative for enhancing financial stability by reducing the threat of financial disintermediation. The study concludes that cryptocurrency and CBDCs have the potential for transformation, but CBDCs align more with existing financial systems to support monetary policy and ensure financial stability. A comparative analysis was carried out to underline further that CBDCs provide, compared to cryptocurrencies, a more predictable and better-controlled environment for economic management, making them a more desirable option for central banks globally.

This paper discusses the multifaceted landscape of Central Bank Digital Currency (CBDC), examining its historical evolution, present implications, and prospects. Beginning with elucidating CBDC’s definition, the study underscores the importance of exploring its intricate dynamics. The evolutionary trajectory of CBDC is traced from its conceptual inception to critical milestones in its development, juxtaposed against traditional currency systems and cryptocurrencies. Furthermore, the paper analyzes the far-reaching implications of CBDC across economic, social, and international spheres. Economic ramifications encompass its impact on monetary policy and financial stability, while social implications touch upon issues of accessibility, inclusivity, and privacy. CBDC’s effects on global financial systems and cross-border transactions are scrutinized internationally. Subsequently, the study navigates the potential benefits and challenges inherent in CBDC adoption, emphasizing efficiency gains in payment systems and reductions in transaction costs, counterbalanced by technological hurdles and regulatory complexities. The prospect and potential scenarios surrounding CBDC adoption are also explored, including adoption trends, central bank roles, and stakeholder collaboration.

Purpose: This study sought to investigate the role of Central Bank Digital Currencies (CBDCs) in monetary policy transmission. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to the role of Central Bank Digital Currencies (CBDCs) in monetary policy transmission. Preliminary empirical review revealed that CBDCs enhanced monetary policy transmission by allowing faster, more direct, and more inclusive central bank interventions. Their effectiveness depended on infrastructure and trust, and while they offered significant benefits, risks like financial disintermediation required careful management. Unique Contribution to Theory, Practice and Policy: The Quantity Theory of Money (QTM), Interest Rate Channel of the Monetary Transmission Mechanism and the Financial Intermediation theory may be used to anchor future studies on Central Bank Digital Currencies (CBDCs). The study recommended phased CBDC implementation, updates to monetary theory, and practical safeguards to maintain financial stability. It also urged legal and regulatory reforms, promoted financial inclusion, and called for more research on CBDCs’ long-term economic impacts.

An overview of the definitions of central bank digital currency (CBDC), formulated by researchers of the International Monetary Fund (IMF), the Bank for International Settlements (BIS), the Bank of England, is presented, and the essence of the CBDC is revealed. It is stated that the existing electronic money is a digital form of obligations of financial intermediaries, and CBDC is a form of emission and obligations of central banks. The types and forms of CBDC are generalized, namely: retail or wholesale, account-based or token-based ones. The structure and functionality of the register, payment authentication, access to infrastructure, and governance are defined as factors taken into account during CBDC designing. Similar models of launching national CBDC by the Bank of England (economy-wide access or financial institutions access, and financial institutions plus CBDC backed narrow bank access) and BIS (direct, indirect, hybrid) are under consideration. The synthetic CBDCs are marked as a theoretical concept of CBDC. The overview of projects of the People's Bank of China – "e-renminbi", the Central Bank of the Uruguay – "e-peso", the Central Bank of the Bahamas – "sand dollar" and the Eastern Caribbean Central Bank affirm the interest of developing countries in launching national retail CBDCs. It was found that apart from the Riksbank with the successful "e-krona" project, most of the monetary authorities of developed countries (BIS, Bank of Japan, Bank of Canada, Deutsche Bank, FRS) are just planning or starting to experiment with the issuance of digital securities, which demonstrates their concern about the restructuring of the banking system and the changes of global role of traditional currencies. Among the positive consequences of the introduction of CBDC for the domestic banking system are the emergence of an alternative payment instrument, the implementation of effective monetary policy through increased influence on interest rates, and regulation of the legal regime of crypto currencies. At the same time, the introduction of CBDC involves certain changes in financial intermediation (replacement of the deposits of commercial banks with the CBDC, the performance of functions inherent to commercial banks by the central bank or fintech companies), and will require powerful technical capabilities, including those related to protection from cyber risks. The results of the study point to the need for a cautious approach to the implementation of the Ukrainian CBDC only after the NBU assesses the public demand for new forms of money and the impact of the launch of CBDC models on price and financial stability, and compares available payment technologies that can achieve the same goals as the CBDC.

Central bank digital currencies and financial stability in a modern monetary system

Central Bank Digital Currency and Financial Stability

This paper aims to examine the revolutionary impact of digital technologies—specifically blockchain systems and central bank digital currencies (CBDCs)—on modern financial architecture and the processes of global economic integration. These technologies are rapidly transforming the structure and functioning of both national and international financial systems, placing states, markets, and institutions before new opportunities and challenges within the contemporary economic landscape. Blockchain technology, as one of the core components of Industry 4.0, is widely applied in areas such as peer-to-peer (P2P) transactions, trade finance, smart contracts, digital asset tokenization, and data protection. This research highlights its influence on the functional structure of financial markets, particularly in the context of international payments, transaction transparency, and cybersecurity. Simultaneously, the study explores the evolving role of traditional financial institutions—especially central banks—in the digital age. In Georgia, the emergence of blockchain-based startups in areas like payments, digital contract management, and data security is already evident, positioning this technology as a potential driver of economic transformation in the country. CBDCs, as digital currencies issued by central banks and directed both toward the general public (retail CBDC) and financial institutions (wholesale CBDC), differ from other digital innovations by serving as a strategic instrument that bridges monetary policy, sovereign currency systems, and international financial relations. In addition to blockchain, this study analyzes the potential role of CBDCs in global economic integration—specifically how they support the optimization of cross-border payment systems, increase financial inclusion, and strengthen digital sovereignty, particularly for developing economies. Furthermore, it addresses the geopolitical and regulatory complexities that accompany the global implementation of these technologies. Methodologically, the research employs a mixed-methods approach. The impact of blockchain is evaluated using financial market indicators from Yahoo Finance and Bloomberg, as well as global digital governance indices. The analysis of CBDCs relies on documentary review, including reports from international organizations (e.g., IMF, BIS, World Bank), academic literature, and regulatory frameworks developed by central authorities. The paper is structured as follows: the first section discusses the theoretical and practical aspects of blockchain technology; the second section focuses on the technological and policy foundations of CBDCs; the third section examines their impact on areas such as international trade, financial policy, monetary independence, and cybersecurity. Finally, the case of Georgia is presented as an example of the combined influence of blockchain and CBDCs in an emerging economy. The study’s main conclusion demonstrates that the integration of blockchain and CBDCs is transforming the rules of the game in financial markets. The technological architecture is shifting to a new digital paradigm, where fast, low-cost, and secure transactions are replacing traditional financial intermediaries. Simultaneously, the role of central banks is being strengthened in monetary and credit policy, while their responsibilities regarding cybersecurity and data protection are also expanding. Successful implementation of CBDCs will significantly enhance both domestic financial stability and participation in global monetary relations—provided that international cooperation, legal frameworks, and technical standardization are effectively developed. Similarly, the application of blockchain technology—particularly in Georgia—requires a strategic vision and infrastructure support to harness its potential not only for improving financial products but also for fostering economic development and integration into the global system. Therefore, this paper confirms that the digital technology revolution—namely blockchain and CBDCs—represents not only a technological shift but a profound structural transformation in the global financial architecture, requiring integrated policy approaches and coordinated actions at both national and international levels. Keywords: Blockchain technologies, digital currency, central bank, financial markets, economic integration, Georgian economy, CBDC, international trade, monetary policy.
