This paper examines the correlation of economic policy uncertainty (EPU) with nonperforming loans and loan loss provisions for 22 major developed countries over the 2008–2017 period.

The study used the Pearson correlation methodology to assess the correlation between EPU, bank nonperforming loans and loan loss provisions.

The findings reveal that EPU is negatively correlated with nonperforming loans and loan loss provisions in the banking sector of EU countries but not for non-EU countries. Also, EPU is negatively correlated with nonperforming loans in the banking sector of the most advanced economies – the G7 countries, while loan loss provisions are more responsive to changes in EPU than NPLs in EU countries.

The implication of the findings is that the correlation of EPU with loan loss provisions and nonperforming loans is influenced by regional characteristics.

This study is the first to analyze the association of EPU with bank nonperforming loans and loan loss provisions under regional classifications such as the EU, non-EU and the G7 countries. This study provides insights on how regional differences might explain the co-movement of EPU with bank nonperforming loans and loan loss provisions.

This study examines the impact of competition and concentration on bank income smoothing in Central and Eastern European (CEE) countries.

The two-step system GMM method was used to analyse the impact of competition and concentration on bank income smoothing in 17 CEEs from 2004 to 2015.

Loan loss provisions (LLPs) are negatively related to bank competition and concentration. The authors find no evidence for income smoothing using LLPs in a high-competition or high-concentration environment.

A limitation of the study is that the analysis was restricted to commercial banks. The authors did not examine investment banks or microfinance banks in this study. Also, not having access to databases does not allow them to include recent years in the study.

CEE commercial banks will likely keep fewer provisions or engage in under-provisioning when they face intense competition, and this can expose them to credit risk, which may threaten their stability.

This study is the first to investigate the effect of concentration and competition on income smoothing among CEE banks.

The purpose of this study is to discuss the role of central bank digital currency (CBDC), Fintech and cryptocurrency for financial inclusion and financial stability.

This study used critical discourse analysis to identify the benefits and risks of CBDC, Fintech and cryptocurrency for financial inclusion and financial stability.

Fintech, CBDC and cryptocurrency can increase financial inclusion by providing an alternative channel through which unbanked adults can access formal financial services. CBDC and Fintech services have the potential to preserve financial stability, while cryptocurrency presents financial stability risks that can be mitigated through effective regulation. This paper also identified some problems of CBDC, Fintech and cryptocurrency for financial inclusion and financial stability. This paper offered some insight about the future of financial inclusion and the future of financial stability.

Although CBDC, Fintech or cryptocurrency can extend financial services to unbanked adults and offer cost-efficient advantages, there are risk considerations that need to be taken into account when using CBDC, Fintech and cryptocurrency to increase financial inclusion and to preserve financial stability.

The literature has not identified the combined role of CBDC, Fintech and cryptocurrency for financial inclusion and financial stability. To the best of the author’s knowledge, this paper is the first paper to assess the combined role of CBDC, Fintech and cryptocurrency for financial inclusion and financial stability.

This paper aims to investigate the determinants of global interest in central bank digital currency (CBDC). It assessed whether global interest in sustainable development and cryptocurrency are determinants of global interest in CBDC.

Google Trends data were analyzed using two-stage least square regression estimation.

There is a significant positive relationship between global interest in sustainable development and global interest in CBDC. There is a significant positive relationship between global interest in cryptocurrency and global interest in the Nigeria eNaira CBDC. There is a significant negative relationship between global interest in CBDC and global interest in the eNaira CBDC. There is a significant positive relationship between global interest in CBDC and global interest in the China eCNY. There is a significant negative relationship between global interest in cryptocurrency and global interest in the Sand Dollar and DCash.

The literature has not empirically examined whether global interest in sustainable development and cryptocurrency are factors motivating global interest in CBDC. This study fills a gap in the literature by investigating whether global interest in sustainable development and cryptocurrency are factors motivating global interest in CBDC.

This article analyses the trend in women digital financial inclusion in Nigeria using some digital financial inclusion indicators obtained from the global Findex database for the year 2014, 2017 and 2021. The study also analyses the relationship between women digital financial inclusion and economic growth.

The data were analysed using the two-stage least squares (2SLS) and generalised method of moments (GMM) regression estimation methods. The women digital financial inclusion indicators are the percentage of women who (1) own a mobile money account, (2) made a digital payment, (3) received digital payments, (4) made or received a digital payment, (5) own a credit card and (6) own a debit card.

The trend analysis shows a sustained, although small, improvement in women mobile money account ownership during the period, while the other indicators witnessed a decrease in 2017 and an increase in 2021, except for women credit card ownership which remained at the same level during the period examined. There is a significant positive relationship between women digital financial inclusion and economic growth. Internet usage has a significant positive effect on women digital financial inclusion in Nigeria.

Greater digital financial inclusion for women can accelerate economic growth in Nigeria. Policymakers should encourage investment in fintech and broaden access to the Internet to increase women digital financial inclusion and economic growth in Nigeria. Policymakers and practitioners in Nigeria should also work collaboratively to increase digital financial inclusion for women due to its potential to increase economic growth in Nigeria.

Existing studies did not analyse the trends in women digital financial inclusion. Existing studies did not empirically analyse the impact of women digital financial inclusion on economic growth in Nigeria. The present study fills this gap in the literature.

This paper investigates the global and local interest in Internet information about cryptocurrency and the Nigeria central bank digital currency, which is also known as eNaira.

Granger causality test and GMM coefficient matrix methodologies were used.

There is sustained increase in global and local interest in Internet information about eNaira in the first six weeks after eNaira adoption. Local interest in Internet information about cryptocurrency in Nigeria exceeded global interest in Internet information about cryptocurrency. The south-east region had the highest interest in cryptocurrency information followed by the south-south, the north-central, the north-east, the north-west and the south-west regions. In contrast, the north-east region had the highest interest in Internet information about eNaira, followed by the north-west, the north–central, the south-west, the south-south and the south-east regions. Nigeria recorded the highest global interest in Internet information about cryptocurrency and eNaira, while Japan and Brazil recorded the lowest interest during the period. The correlation results show a significant and positive correlation between interest in cryptocurrency information and interest in eNaira information. The Granger causality results show that global interest in cryptocurrency information causes both global and local interest in eNaira information. Also, local interest in cryptocurrency information causes global interest in eNaira information. The GMM regression coefficient matrix shows a significant positive relationship between interest in cryptocurrency information and eNaira information.

There are few studies on CBDC in country-specific contexts. This study adds to the literature by examining the Nigerian context.

This paper aims to investigate the correlation between banking sector non-performing loans (NPLs) and the level of sustainable development.

Pearson correlation test statistic was used to assess the correlation between bank NPLs and sustainable development.

There is a significant positive correlation between banking sector NPLs and the level of sustainable development measured by the sustainable development index (SDI). The significant positive correlation is evident in European countries and in countries in the region of the Americas. There is a significant negative correlation between banking sector NPLs and achieving SDG3 and SDG7 in African countries and European countries. There is also a significant negative correlation between NPLs and achieving SDG10 in European countries. There is a significant positive correlation between banking sector NPLs and achieving SDG4 and SDG7 in the region of the Americas. There is also a significant positive correlation between NPLs and achieving SDG10 in African countries and in countries in the region of the Americas.

The present study is unique and different from other studies because it used a unique SDI to capture the level of sustainable development. The analysis is also unique because it covers several regions, which have not been covered in previous studies.

This 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.

Two-stage least squares regression and granger causality test were used to analyze the data.

Inflation 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.

There 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.

This paper examines the association between corporate governance and financial inclusion in terms of correlation. This paper examines whether countries that have a strong corporate governance environment also experience better financial inclusion outcomes.

The indicators of financial inclusion are automated teller machines (ATMs) per 100,000 adults, bank accounts per 1,000 adults and bank branches per 100,000 adults, while the indicators of corporate governance are extent of corporate transparency index, the extent of director liability index, the extent of disclosure index, the extent of ownership and control index, the extent of shareholder rights index, minority investors protection index and ease of shareholder suits index. The association was analyzed using Pearson correlation analysis and granger causality test.

Strong corporate governance is significantly associated or correlated with better financial inclusion outcomes. The regional analyses show that corporate governance has a significant positive association with financial inclusion in Asian countries and in Middle East countries. However, a positive and negative association was observed between some indicators of corporate governance and financial inclusion in European countries, North American countries, South American countries, African countries and in Middle East and North Africa (MENA) countries, implying that strong corporate governance has a positive and negative association with financial inclusion depending on the indicators of corporate governance and financial inclusion used. There is also evidence of uni-directional granger causality between corporate governance and financial inclusion.

Little is known about the association between corporate governance and financial inclusion. This paper is the first to examine this association.

This paper aims to investigate the association between financial inclusion and sustainable development in a global context.

The study used two datasets, and employed the Pearson correlation analysis and granger causality test to examine the correlation and pairwise causality between financial inclusion and sustainable development.

High levels of financial inclusion (in terms of higher commercial bank branches per 100,000 adults) is significantly associated with higher electricity production from renewable sources, higher industry productivity, higher adult literacy rate and higher renewable electricity output. Also, higher financial inclusion is significantly associated with low combustible renewables and waste. There is a uni-directional granger causality between global interest in internet information about sustainable development and global interest in internet information about financial inclusion, particularly in the period after the global financial crisis but before the COVID-19 pandemic.

The correlation between financial inclusion and sustainable development depends on the indicators employed to measure financial inclusion and sustainable development. The results support global calls for greater financial inclusion and the speedy attainment of the sustainable development goals for the good of all people, the environment and for the planet.

This paper is the first study in the literature to analyze the link between financial inclusion and sustainable development using global data. This study contributes to the existing literature by investigating the association between financial inclusion and sustainable development in a global context.
