Central Bank Digital Currency in an Emerging Market Economy: Case of the Central Bank of the Republic of Türkiye

Central banks have historically been using traditional channels for communication and physical money for transactions, fulfilling the needs of previous millennia, while the evolution of technology, electronic devices, and needs in transactions necessitate the use of modern communication channels, such as X (formerly known as Twitter), as well as modern payment systems, such as central bank digital currencies (CBDC). Hence, this paper aims to unfold where the Central Bank of the Republic of Türkiye (CBRT), as an example of emerging markets, stands in informing the public about CBDC. To this end, it conducts an event study on the official X account of CBRT in English over 10.2020-12.2022 by utilizing Nvivo. The findings of the quantitative analysis of the tweets show that CBRT does not regard X as a primary communication channel and mainly shares links to publications from the official websites in X. Also, CBRT tends to adopt a ‘cold-turkey’ informative approach about CBDC with the public rather than ‘gradualism’. Consequently, CBRT should rigorously design a communication strategy that fulfills the needs of the modern economy and start addressing CBDC to raise awareness if a quick transition to digital currency is targeted.

Technology and monetary sovereignty: Understanding motivations for central bank digital currencies

Central bank digital currency (CBDC) projects have advanced the furthest in small or developing economies. In contrast, central banks in wealthy countries where technologies that fuelled this trend developed are holding back on such plans. What explains this divergence? I argue that CBDCs are attractive to states which see them as useful to increase and reinforce sovereignty over economic territory. They have thus been adopted in states with high currency substitution, large informal economies, or limited reach of the banking system. For similar reasons, wealthier states see less need for CBDCs. This paper contributes to understanding the impacts of digital money on the spatial dynamics of monetary politics.

A simple model of a central bank digital currency

We develop a general equilibrium model that highlights the trade-offs between physical and digital forms of retail central bank money. The key differences between cash and central bank digital currency (CBDC) include transaction efficiency, possibilities for tax evasion, and, potentially, nominal rates of return. We establish conditions under which cash and CBDC can co-exist and show how government policies can influence relative holdings of cash, CBDC, and other assets. We illustrate how a CBDC can facilitate negative nominal interest rates and helicopter drops, and also how a CBDC can be structured to prevent capital flight from other assets.

The impact of CBDC on a deposit-dependent banking system

We examine implications of a central bank digital currency (CBDC) for banks using business models particularly dependent on customer deposits. Employing unique customer data hand-collected from German savings and cooperative banks, we generate conversion rates for deposits into a CBDC. Even at moderate conversion rates, most banks would have experienced funding problems and lost profits if a CBDC had been introduced in most years from 2000 onward. Our results are relevant for commercial banks, contributing to better assessments of the impact of CBDCs on liquidity and profitability and help central banks to identify implementation costs for banks within historical and hypothetical interest rate environments.

Does news related to digital economy and central bank digital currency affect digital economy ETFs? Evidence from TVP-VAR connectedness and wavelet local multiple correlation analyses

The rapid and widespread digitalization of economies warrants a better understanding of its impact on society and economy. This study contributes to this new but important research agenda by examining how news on digitalization affects digital economy related exchange traded funds (ETFs). For this purpose, we first construct a digital economy attention index by utilizing Google Search Volume Index for several keywords. Then, using this index and two other indices that represent attention and uncertainty related to central bank digital currency (CBDC), we examine the time-varying connectedness and correlations between these three indices and digital economy ETFs. Our TVP-VAR frequency connectedness analysis shows that attention to and uncertainty around the CBDC and digital economy have strong connectedness with the ETFs in the short-term. The analysis also shows that CBDC and digital economy indices are mainly net transmitters of shocks while the majority of the ETFs are the net receivers of the shocks. The results of our wavelet local multiple correlation (WLMC) analysis show that the correlations between ETFs, digital economy and CBDC indices are time- and frequency-dependent. Moreover, both connectedness and correlations are affected by CBDC-related global events and COVID-19 pandemic. The time- and frequency-dependent relation requires active management of the portfolios containing digital economy related assets.

Central bank digital currency, economic growth and inflation

PurposeThis study aims to investigate the effect of CBDC issuance on economic growth rate and inflation rate in Nigeria. We are interested in determining whether the rate of economic growth and inflation changed significantly after the issuance of a non-interest bearing CBDC in Nigeria.Design/methodology/approachTwo-stage least squares regression and granger causality test were used to analyze the data.FindingsInflation significantly increased in the CBDC period, implying that CBDC issuance did not decrease the rate of inflation in Nigeria. Economic growth rate significantly increased in the CBDC period, implying that CBDC issuance improved economic growth in Nigeria. The financial sector, agricultural sector and manufacturing sector witnessed a much stronger contribution to gross domestic product (GDP) after CBDC issuance. There is one-way granger causality between CBDC issuance and monthly inflation, implying that CBDC issuance causes a significant change in monthly inflation in Nigeria. The implication of the result is that the non-interest bearing eNaira CBDC is not able to solve the twin economic problem of “controlling inflation which stifles economic growth” and “stimulating economic growth which leads to more inflation.” Policy makers should therefore use the eNaira CBDC alongside other monetary policy tools at their disposal to control inflation while stimulating growth in the economy.Originality/valueThere are no empirical studies on the effect of CBDC issuance on economic growth or inflation using real-world data. We add to the monetary economics literature by analyzing the effect of CBDC issuance on economic growth and inflation.

On the Potential Hedging Instruments Against Central Bank Digital Currency Uncertainty and Attention Indices

We study dynamic conditional correlations of Central Bank Digital Currency (CBDC) uncertainty and attention indices with US dollar futures, 1-year US government bond, and gold futures. We find that USD futures hedges CBDC uncertainty, while the US bond hedges the CBDC uncertainty index subsequent to 2019. Interestingly, gold does not hedge CBDC uncertainty. The CBDC attention index exerts a negative effect on the other assets. These results are important for portfolio management.

OPTIMAL CENTRAL BANK DIGITAL CURRENCY DESIGN FOR EMERGING ECONOMIES

The growth of digitalisation presents the possibility for Central Bank Digital Currency (CBDC) to emerge as a secure and efficient payment method. However, despite the benefits, CBDC implementation needs to be adapted to the capabilities and needs of each country. This study uses meta-strength, weakness, opportunity, and threat (meta-SWOT) analysis to assess the internal strengths and weaknesses, as well as the external opportunities and threats, to determine the most optimal CBDC design for emerging economies. In analysing internal aspects, CBDC allows for an efficient payment system, followed by a more effective monetary policy. Furthermore, the technology creates the possibility to boost financial inclusion and trace many illicit activities. However, to achieve that, high investment costs and privacy issues must be accommodated, followed by technological risks such as the digital divide and electrical outages. Turning to external aspects, growing technology, the network effect, enthusiasm for CBDC, and the impracticality of cash usage have become catalysts for CBDC development. Despite these opportunities, central banks should be wary of the threat of cyberattacks, quickening bank disintermediation, legal issues within their respective countries, and competition with private crypto companies. Altogether, the most optimal CBDC design in emerging economies is retail and wholesale coverage, interest-bearing (wholesale) and noninterest-bearing (retail) remuneration, account-based and token-based paymentsystems, a traceable degree of anonymity, hybrid architecture, a Decentralised Ledger Technology (DLT) ledger system, and domestic and cross-border scope. These results are supported by rigorous examination of global CBDC research and development.

Cross-Border Payments with Retail Central Bank Digital Currencies

Cross-Border Payments with Retail Central Bank Digital Currencies

Retail CBDC purposes and risk transfers to the central bank

The issuance of retail central bank digital currency (CBDC) involves a transfer of risk from commercial banks to the central bank. Mechanisms that limit the transfer of risk, such as an unattractive interest rate, a quantity ceiling or the non-convertibility of cash and reserves into CBDC, are likely to discourage the use of CBDC as a medium of exchange and thus defeat the purpose of issuing CBDC.
