法定数字货币运行的国际实践及启示

以比特币为代表的私人数字货币虽本质上不具备货币职能,但已对现行的货币与金融体系构成了巨大挑战。为应对这一挑战,各国央行正在积极研发或推行法定数字货币。对相关国家法定数字货币运行实践比较的结果表明:现有的法定数字货币大多以区块链技术为基础并由本国央行集中发行,主要采用双层运营体系;批发型设计有利于提高运行效率和金融安全,零售型设计则更有利于应用场景推广以满足不同需求;能否稳定币值事关法定数字货币试点成败。我国在研发法定数字货币的过程中应遵循稳步、安全、可控原则,尽快制定法定数字货币的相关法律法规,加大数字货币技术创新的研究力度,丰富应用场景,深化法定数字货币研发的国际合作。

Introducing New Forms of Digital Money: Evidence from the Laboratory

Central banks may soon issue currencies that are entirely digital (CBDCs) and possibly interest bearing. A strategic analytical framework is used to investigate this innovation in the laboratory, contrasting a traditional “plain” tokens baseline to treatments with “sophisticated” interest-bearing tokens. In the experiment, this theoretically beneficial innovation precluded the emergence of a stable monetary system, reducing trade and welfare. Similar problems emerged when sophisticated tokens complemented or replaced plain tokens. This evidence underscores the advantages of combining theoretical with experimental investigation to provide insights for payments systems innovation and policy design.     

Money in the time of crypto

This paper investigates the evolution of cryptocurrencies. By nature and essence, Bitcoin challenged and implicitly threatened central bank money and its role in the monetary system. Meanwhile, central banks have been studying cryptocurrencies and launched pilot projects on their own digital currency, the Central Bank Digital Currency. Until recently, most economists considered Bitcoin merely as a speculative asset; however, the El Salvador decision in 2021 to establish it as a legal tender (through the Bitcoin Law) questions the status quo perception of Bitcoin. Given El Salvador’s legal obligation by law of their acceptance, allowing tax payments to the government and debts to be settled using Bitcoin, the Bitcoin Law challenges the boundaries of money. In light of the El Salvador experience, we consider different perspectives on the nature of money, allowing us to reject or include Bitcoin inside the money spectrum.     

Return spillover analysis across central bank digital currency attention and cryptocurrency markets

Many central banks have now developed their digital currencies in response to the challenges posed by the proliferation of decentralised digital cryptocurrencies. However, little is known about the effects of the introduction of central bank digital currencies (CBDCs) on extant digital cryptocurrencies. This paper, therefore, aims to identify both the time- and frequency-domain spillover effects among cryptocurrency markets and a newly developed central bank digital currencies attention index (CBDCAI) by using two TVP-VAR-based spillover models. Our results demonstrate that CBDC attention significantly impacts cryptocurrency markets. Also, most investors in cryptocurrency markets are more likely to trade in the short term. The results of this study contribute to helping investors and investment institutions effectively avoid investment risks, reduce losses, and predict the return of some cryptocurrencies. Also help policymakers better understand the impact of markets and policies, and provide a reference for them to formulate policies.     

Digital currencies in financial networks

We introduce a central bank digital currency (CBDC) in the network of financial accounts. Simulating a shift of deposits by both households and non-financial corporations from the banking sector to the central bank, we model the different responses of the affected institutional sectors. We find that the introduction of CBDC generates funding shortages in banks, which may propagate to other sectors. In addition, significant adjustments in the balance sheets of all sectors trigger large moves in securities prices and induce changes in the financial network structure. Finally, we extend the analysis to the introduction of a crypto financial asset (stablecoin) issued by either a domestic or a foreign entity.     

Investigating individual privacy within CBDC: A privacy calculus perspective

Central Bank Digital Currencies (CBDC) are a digital innovation based upon distributed ledger and smart contract technology. In this paper we examine how potential users of CBDC technology willingly disclose their personal information. The researchers conducted an online quantitative survey which investigates the privacy perceptions of consumers. Using the privacy calculus theory lens, this study looks at the potential benefits of CBDC and how these influence user perceptions towards privacy disclosure. While this research suggests that participants in the study had negative perceptions in relation to the disclosure of personal information, many were willing to offset these concerns if there are significant benefits in the usage of CBDC. Factors such as ease of use, convenience, availability, and credibility were viewed as key benefits in this scenario. Thus, future banking strategies and marketing approaches need to consider these components to foster CBDC adoption.     

Central bank digital currency: A systematic literature review using text mining approach

Central bank digital currency (CBDC) is seen as a possible next step in the evolution of money, offering a more stable unit of account, a more efficient medium of exchange, and a safer way to store value. However, since it began to get significant attention from academics and practitioners a few years ago, many concerns about how a central bank may build an efficient CBDC and how it would impact a country's current financial system still remain unanswered satisfactorily. Based on the combination of text mining and systematic review methods, this work presents a thorough literature assessment of 191 academic papers on CBDC in order to identify major research issues and knowledge gaps that may be addressed in the future. We find seven primary research themes linked to CBDC including (1) Central bank, (2) CBDC and other digital currency, (3) CBDC and money markets, (4) CBDC and monetary policy, (5) CBDC design and technologies, (6) CBDC and payment system, and (7) CBDC and financial stability and regulatory. The finding helps provide both overall and in-depth views of the current state of research in digital fiat currency topics, as well as drawing some important implications and suggestions on directions for the future research.     

The impact of central bank digital currency news on the stock and cryptocurrency markets: Evidence from the TVP-VAR model

This study employs a non-linear framework to investigate the impacts of central bank digital currency (CBDC) news on the financial and cryptocurrency markets. The time-varying vector autoregressive (TVP-VAR) model developed by Primiceri (2005) is estimated based on weekly data from the first week of January 2015 to the last week of December 2021. The vector of endogenous variables in the VAR estimation contains the Central Bank Digital Currency uncertainty index (CBDCU), cryptocurrency policy uncertainty index, S&P 500 index, VIX, and Bitcoin price. The TVP-VAR model’s time-varying responses demonstrated that the reactions of the cryptocurrency market to central bank digital currency announcements vary remarkably over time. The impacts of the CBDC shocks on the financial market have been increasingly visible during the COVID-19 pandemic. According to the time-varying forecast error decompositions, CBDCU and VIX shocks have accounted for most of the variance in cryptocurrency uncertainty and Bitcoin return shocks, notably during the COVID-19 period.
