Abstract

Purpose

In this paper the interconnectedness among financial institutions and the level of systemic risks of four types of Chinese financial institutions are investigated.

Design/methodology/approach

By the means of RAS algorithm, the interconnection among financial institutions are illustrated. Different methods, including Linear Granger, Systemic impact index (SII), vulnerability index (VI), CoVaR, and MES are used to measure the systemic risk exposures across different institutions.

Findings

The results illustrate that big banks are more interconnected and hold the biggest scales of inter-bank transactions in the financial network. The institutions which have larger size tend to have more connection with others. Insurance and security companies contribute more to the systemic risk where as other institutions, such as trusts, financial companies, etc. may bring about severe loss and endanger the financial system as a whole.

Practical implications

Since other institutions with low levels of regulation may bring about higher extreme loss and suffer the whole system, it deserves more attention by regulators considering the contagion of potential risks in the financial system.

Originality/value

This study builds a valuable contribution by examine the systemic risks from the perspectives of both interconnection and tail risk measures. Furthermore; Four types financial institutions are investigated in this paper.

Abstract

Purpose

While previous literature has emphasized the causal relationship from liquidity to capital, the impact of interbank network characteristics on this relationship remains unclear. By applying the interbank network simulation, this paper aims to examine whether the causal relationship between capital and liquidity is influenced by bank positions in the interbank network.

Design/methodology/approach

Using the sample of 506 commercial banks established in 28 European countries from 2001 to 2013, the author adopts the generalized method of moments simultaneous equations approach to investigate whether interbank network characteristics influence the causal relationship between bank capital and liquidity.

Findings

Drawing on a sample of commercial banks from 28 European countries, this study suggests that the interconnectedness of banks within interbank loan and deposit networks shapes their decisions to establish higher or lower regulatory capital ratios in the face of increased illiquidity. These findings support the implementation of minimum liquidity ratios alongside capital ratios, as advocated by the Basel Committee on Banking Regulation and Supervision. In addition, the paper underscores the importance of regulatory authorities considering the network characteristics of banks in their oversight and decision-making processes.

Originality/value

This paper makes a valuable contribution to the current body of research by examining the influence of interbank network characteristics on the relationship between a bank’s capital and liquidity. The findings provide insights that add to the ongoing discourse on regulatory frameworks and emphasize the necessity of customized approaches that consider the varied interbank network positions of banks.

Abstract

Purpose

The purpose of this paper is to study the evolution of financial contagion between Eurozone banks, observing the credit default swaps (CDSs) market during the period 2009–2017.

Design/methodology/approach

The authors use a dynamic spatial Durbin model that enables to explore the direct and indirect effects over the short and long run and the transmission channels of the contagion.

Findings

The results show how contagion emerges through physical and financial market links between banks. This finding implies that a bank can fail because people expect other related financial institutions to fail as well (self-fulfilling crisis). The study provides statistically significant evidence of the presence of credit risk spillovers in CDS markets. The findings show that equity market dynamics of “neighbouring” banks are important factors in risk transmission.

Originality/value

The research provides a new contribution to the analysis of EZ banking risk contagion, studying CDS spread determinants both under a temporal and spatial dimension. Considering the cross-dependence of credit spreads, the study allowed to verify the non-linearity between the probability of default of a debtor and the observed credit spreads (credit spread puzzle). The authors provide information on the transmission mechanism of contagion and, on the effects among the largest banks. In fact, through the study of short- and long-term impacts, direct and indirect, the paper classify banks of systemic importance according to their effect on the financial system.

Abstract

Purpose

Shadow banks or non-bank financial intermediaries (NBFIs) are facilitators of credit, especially in emerging market economies (EMEs). However, there are certain risks associated with them, such as their unchecked leverage and interconnectedness with the rest of the financial system. In light of this, the present study analyses the impact of the growth of shadow banks on the stability of the banking sector and the overall stability of the financial system. The authors further examine the effect of the growth of finance companies (a type of NBFIs) on financial stability.

Design/methodology/approach

The study employs data of 11 EMEs (monitored by the Financial Stability Board (FSB)) for the period 2002–2020 to examine the above relationships. Panel-corrected standard errors method and Driscoll–Kray standard error estimation are deployed to conduct the analysis.

Findings

The results signify that the growth of the shadow banking sector and the growth of lending to the shadow banking sector are negatively associated with the stability of the banking sector and increases the vulnerability of the financial system (overall instability). This implies that the higher the growth of the shadow banks, the higher the financial fragility. Finance companies are also found to negatively affect financial stability. These findings are validated by different estimation methods and point out the risks posed by the NBFI sector.

Originality/value

The extant study builds a composite index (Financial Vulnerability Index (FVI)) to measure financial stability; thus, the findings contribute to the evolving literature on shadow banks.

Abstract

Purpose

In this paper, the authors use the balance sheet data to investigate the interconnectedness and risk contagion effects in China's banking sector. They firstly study the network structure and centrality of the interbank network. Then, they investigate how and to what extent the credit shock and liquidity shock can lead to the risk propagation in the banking network.

Design/methodology/approach

Referring to the theoretical framework by Haldane and May (2011), this paper uses the network topology theory to analyze the contagion mechanism of credit shock and liquidity shock. Centrality measures and log-log plot are used to evaluate the interconnectedness of China's banking network.

Findings

The network topology has shown clustering effects of large banks in China's financial network. If the Industrial and Commercial Bank of China (ICBC) is in distress, the credit shock has little impact on the Chinese banking sector. However, the liquidity shock has shown more substantial effects than that of the credit shock. The discount rate and the rollover ratio play significant roles in determining the contagion effects. If the credit shock and liquidity shock coincide, the contagion effects will be amplified.

Research limitations/implications

The results of this paper reveal the network structure of China's interbank market and the resilience of banking system to the adverse shock. The findings are valuable for regulators to make policies and supervise the systemic important banks.

Originality/value

The balance sheet data of different types of banks are used to construct a bilateral exposure matrix. Based on the matrix, this paper investigates the knock-on effects of credit shock triggered by the debt default in the interbank market, the knock-on effects of liquidity effects, which is featured by “fire sale” of bank assets, and the contagion effects of combined shocks.

Abstract

Purpose

The unhealthy drive for deposit in the banking sector has pushed many banks into unethical practices, thereby resulting in high-level corruption cases in the banking sector. The purpose of this study is to investigate the short- and long-run linkages between bank net interest income and deposit liabilities interacted with corruption, to establish the influence of corruption in deposit mobilisation drive of banks in Nigeria. Also, the study analysed the causal relationship between selected bank variables and fraud.

Design/methodology/approach

The study used quarterly data on selected variables from 1Q 1993 to 4Q 2017 sourced from Nigerian Deposit Insurance Corporation (NDIC) annual reports and Central Bank of Nigeria (CBN) Statistical Bulletin of various issues. Deposit Money Bank various deposit liabilities are interacted with a corruption index and used as the independent variables, while bank earnings serve as the dependent variable. Error Correction Model (ECM) and Engel Granger approach to co-integration technique were used to analyse the data.

Findings

The findings reveal that various bank deposit liabilities interacted with corruption index has a negative effect on bank profitability in the long run, though only corrupt fixed deposit is statistically significant at the 5 per cent significance level. Bank total asset, total loan and advances and fraud have a significant effect on bank profitability at 1 and 10 per cent significance level. The findings also reveal that banks profit from corrupt fixed deposit and demand deposit in the short run.

Social implications

Text

Originality/value

The literature is awash with bank lending corruption and various institutional factors such as competition among banks, credit bureau and information sharing about borrowers, bank supervisory policies, loan loss provisioning, bank ownership structure and regulatory environment and anti-corruption measures. The aspect of deposit mobilisation and corruption has not been well researched in literature; this study, therefore, fills the gap in the literature by examining the extent deposit money banks contributed to corruption in Nigeria through their cutthroat deposit mobilisation drive.

Abstract

Purpose

Despite the sophisticated regulatory regime established in Solvency II, analysts should be able to consider other less complex indicators of the soundness of insurers. The Z-score measure, which has traditionally been used as a proxy of individual risk in the banking sector, may be a useful tool when applied in the insurance sector. However, different methods for calculating this indicator have been proposed in the literature. This paper compares six different Z-score approaches to examine which one best fits insurance companies. The authors use a final dataset of 183 firms (1,382 observations) operating in the Spanish insurance sector during the period 2010–2017.

Design/methodology/approach

In the first stage, the authors opt for a root mean squared error (RMSE) criterion to evaluate which of the various mean and SD estimates that are used to compute the Z-score best fits the data. In the second stage, the authors estimate and compare the explanatory power of the six Z-score measures that are considered by using an ordinary least squares (OLS) regression model. Finally, the authors report the results of the baseline equation using the system-GMM estimator developed by Arellano and Bover (1995) and Blundell and Bond (1998) for dynamic panel data models.

Findings

The authors find that the best formula for calculating the Z-score of insurance firms is the one that combines the current value of the return on assets (ROA) and capitalization with the SD of the returns calculated over the full sample period.

Research limitations/implications

The main limitation of the research is that it addresses only the Spanish insurance sector, and consequently, the implications of the findings must be framed in this institutional context. However, the authors think that the results could be extrapolated to other countries. Future research should consider including different countries and analyzing the usefulness of aggregated insurer-level Z-scores for macroprudential monitoring.

Practical implications

The Z-score may be a useful early warning indicator for microprudential supervision. In addition to being an indicator of the soundness of insurers simpler than those established in the current regulation, the information provided by this accounting-based measure may help analysts and investors obtain a better understanding of insurance firms' risk factors.

Originality/value

To the best of the authors’ knowledge, this study is the first to examine and compare different approaches to calculating Z-scores in the insurance sector. The few available results on the predictive power of the Z-score are mixed and focus on the banking sector.

研究目的

雖然在償付能力標準II 內已建立了精密的監管制度,但分析人員應可以考慮以不太複雑的指標,來分析保險公司的穩健程度。Z-分數的估量在銀行業一向作為是個體風險的代理而使用,而Z-分數如應用於保險業,或許會成為有用的工具。唯在文獻裏,學者和研究人員提出了不同的方法來計算這個指標。本文比較六個不同的Z-分數估量方法,以研究出最適合保險公司的方法。我們使用一個最終數據集,包括在2010年至2017年期間在西班牙保險業界營運的183間公司(1382 個觀察)。

研究設計/方法/理念

在首個階段,我們選擇使用一個方均根誤差(RMSE) 標準來衡量用來計算Z-分數的各個平均值和標準差估量中哪個最適合使用於有關的數據。在第二個階段, 我們以普通最小平方 (OLS) 迴歸模型,去估計並比較被考慮的六個Z-分數估量的解釋力。最後,我們以Arellano與Bover (1995), 以及Blundell與Bond (1998) 為動態追蹤資料模型而發展出來的系統-廣義動差估計推定量,來發表我們基線方程式的結果。

研究結果

我們發現,計算保險公司Z-分數的最佳公式是把資產收益率及資本總額的現值,和在整個樣本期間計算出來的囘報的標準差結合起來的公式。

研究的局限/含意

我們研究主要的局限為:研究只涉及西班牙的保險業;因此,研究結果的含意,必須在這個體制的背景框架下來闡釋。唯我們相信研究結果或許可外推至其它國家。未來的研究,應考慮納入不同國家作為研究對象,並分析保險公司層面的集成Z-分數的功用,以求達到宏觀審慎監控的目的。

實際意義

Z-分數或許就微觀審慎監管而言是一個有用的早期警告器。這些以會計為基礎的估量而提供的資訊,除了較現時規例内已建立顯示保險公司穩健程度的各個指標更簡單外,還會幫助分析人員和投資者更了解保險公司的風險因素。

研究的原創性/價值

據我們所知,本研究為首個研究,去探討並比較保險業內的Z-分數的計算方法。以前關於Z-分數預測能力的,為數不多並可供取閱的研究結果均不統一;而且,這些研究都聚焦探討銀行業。

Abstract

The authors estimate systemic risk in the Korean economy using the econometric measures of commonality and connectedness applied to stock returns. To assess potential systemic risk concerns arising from the high concentration of the economy in large business groups and a few export-oriented sectors, the authors perform three levels of estimation using individual stocks, business groups, and industry returns. The results show that the measures perform well over the study’s sample period by indicating heightened levels of commonality and interconnectedness during crisis periods. In out-of-sample tests, the measures can predict future losses in the stock market during the crises. The authors also provide the recent readings of their measures at the market, chaebol, and industry levels. Although the measures indicate systemic risk is not a major concern in Korea, as they tend to be at the lowest level since 1998, there is an increasing trend in commonality and connectedness since 2017. Samsung and SK exhibit increasing degrees of commonality and connectedness, perhaps because of their heavy dependence on a few major member firms. Commonality in the finance industry has not subsided since the financial crisis, suggesting that systemic risk is still a concern in the banking sector.

Abstract

Purpose

Based on the agency and resource dependence theories, this study aims to investigate whether nomination committee (NC) characteristics could serve as key attributes for reducing environmental, social and governance (ESG) disputes and whether NC composition affects the appointment of ESG-friendly directors to the board.

Design/methodology/approach

This study focuses on a sample of 30 global systemically important banks from 2015 to 2021. The authors estimate panel data models with fixed effects, clustering heteroskedastic standard errors at the bank level to account for the serial correlation of the dependent variables for each bank.

Findings

Banks’ exposure to ESG controversies can be reduced when NC members have specific skills, in particular when at least one member of this committee also belongs to the sustainability committee and is a foreign director. Moreover, banks’ ESG disputes decrease when the NC members are younger, while the share of independent NC members has a negative impact. Finally, a positive influence of NC composition and its members’ features as well as the appointment of ESG-friendly directors on the board is found.

Originality/value

The findings are particularly useful during periods such as the current one, when there is growing attention to both banks’ corporate governance, the subcommittees’ role and functioning and social and environmental issues. This study shows that the NC is important in reducing the likelihood of banks incurring ESG disputes and in appointing more ESG-friendly directors. NC effective functioning and its members’ qualities serve as a key attribute for fulfilling objective assessment and improving board effectiveness.

Abstract

Purpose

Existing public–private partnership (PPP) literature that explicitly adopts neo-institutional theory, tends to elucidate the impact of isomorphic pressures and organizational fields and structuration on PPP projects. This paper advances this literature by presenting the institutional work and micro-level dynamics through which actors initiate and implement a new form of project delivery. The authors show how actors enact responses to institutional structuration in the expansion and transformation of an airport from a public entity into a PPP in Saudi Arabia.

Design/methodology/approach

The authors use a single case study design that offers an empirically rich and thick description of events such as the dynamic processes, practices and types of institutional work carried out by actors and organizations to deliver the project under investigation.

Findings

Religious symbolic work as social integration triggered system integration work, which expanded the power capabilities of individual actors leading the project. Repair work then followed to alleviate the negative effects of disempowering the agency of actors negatively affected by the PPP model and to streamline the project implementation process.

Practical implications

This research offers several practical implications. For PPPs to operate successfully in contexts similar to the Gulf region, policymakers should provide strong political support and be willing to bear a considerable risk of losses or minimal outcomes during the early phases of experimentation with PPPs. Also, policymakers should not only focus their attention on technical requirements of PPPs but also associate new meanings with the normative and cultural-cognitive elements that are integral to the success of PPP implementation. In order to design strategies for change that are designed to fit the unique cultural and sociopolitical settings of each country, policymakers should empower capable individual actors and provide them with resources and access to power, which will enable them to enforce changes that diverge from institutionalized practices.

Social implications

This research connected the PPP literature with theoretical frameworks drawn from neo-institutional theory and power. It would be valuable for further research, however, to connect ideas from the PPP literature with other disciplines such as psychology and social entrepreneurship. PPP research examines a recent phenomenon that can potentially be combined with non-traditional streams of research in analyzing projects. Expanding the realm of PPP research beyond traditional theoretical boundaries could potentially yield exciting insights into how the overall institutional and psychological environments surrounding projects affect their initiation and implementation.

Originality/value

The paper contributes new insights regarding the roles of religious symbolic work, allied with social and system integration of power relations in implementing PPP projects. It suggests a theoretical shift from structures and organizational fields – macro- and meso-levels of analysis – to individuals – micro-level – as triggers of new forms of project delivery that break with the status quo.
