Measuring systemic importance of financial institutions: An extreme value theory approach

This paper proposes a set of market-based measures on the systemic importance of a financial institution or a group of financial institutions, each designed to capture different aspects of systemic importance of financial institutions. Multivariate extreme value theory approach is used to estimate these measures. Using six big Canadian banks as the proxy for Canadian banking sector, we apply these measures to identify systemically important banks in Canadian banking sector and major risk contributors from international financial institutions to Canadian banking sector. The empirical evidence reveals that (i) the top three banks, RBC Financial Group, TD Bank Financial Group, and Scotiabank, are more systemically important than other banks, while we also find that the size of a financial institution should not be considered as a proxy of systemic importance; (ii) compared to the European and Asian banks, the crashes of the U.S. banks, on average, are the most damaging to Canadian banking sector, while the risk contribution to the Canadian banking sector from Asian banks is quite lower than that from banks in the U.S. and euro area; (iii) the risk contribution to Canadian banking sector exhibits “home bias”, that is, cross-country risk contribution tends to be smaller than domestic risk contribution.     

How does corporate social responsibility affect financial performance,financial stability,and financial inclusion in the banking sector? Evidence from Pakistan

This paper examines the impact of corporate social responsibility (CSR) on the financial performance, financial inclusion, and financial stability of the banking sector, focusing on annual data for 20 Pakistani commercial banks for the period 2008–2017. The results suggest that CSR, as well as age and size, has a positive impact on all three factors. However, high levels of leverage reduce financial inclusion and financial stability, while financial inclusion is also negatively associated with the tangibility of assets.     

Exploring the nexus between financial sector reforms and the emergence of digital banking culture – Evidences from a developing country

Several financial and banking sector reform programs were instituted in different countries over the last three decades. The underlining purpose of these reforms was largely to improve banking sector supervision and regulation, introduce bank privatization mechanism, introduce clearance and settlement systems, infuse competition and to stimulate financial innovation. The objectives of this study are to 1) review the relevant published literature and market survey reports on the financial & banking sector reforms undertaken in Pakistan and elsewhere, 2) analyze how these reform programs develop digital banking culture and increase financial inclusion in the country and 3) guide future research by putting forward a research agenda. The findings of the study suggest a link between the financial and banking sector reforms and the stimulation of financial innovation; the promotion of digital banking culture; and the infusion of financial inclusion in Pakistan. We discuss managerial/policy implications of the study, limitations and presents recommendations for future research.     

Financial liberalization,insurance market,and the likelihood of financial crises

This paper provides empirical evidence to investigate the direct impact of financial liberalization on the likelihood of currency/systemic banking crises, and examines the roles of insurance market, country risk, and economic conditional variables on the relationship between financial liberalization and financial crises in 39 countries. Our empirical results support that financial liberalization does have a significantly negative impact on the likelihood of currency/systemic banking crises, and that the indirect effects of insurance development and lower country risk decrease the probability of crises, but the indirect effect of economic conditional proxies is enhanced with the likelihood of a financial crisis. The policy implication is that the government or authority should strengthen the positive role of the insurance sector in order to combat financial crises.     

Shadow banking,insurance and financial sector stability

Motivated by the recent financial crisis and the near collapse of the insurance giant American International Group (AIG), we empirically study the link between the insurance sector, the size of the shadow system and financial stability across countries. Using the Z-score as a measure of financial stability and the ratio of insurance assets to GDP for 26 countries during the period 1998–2011, this paper shows that: (i) the insurance sector is negatively and significantly related to financial stability, and that (ii) using the shadow banking system as a channel, the insurance sector is detrimental to financial stability for countries with a high level of shadow banking assets.     

What is the net effect of financial liberalization on bank productivity? A decomposition analysis of bank total factor productivity growth

We employ a unique framework to quantify the net effect of financial liberalization on banks’ total factor productivity (TFP) growth through a decomposition analysis of two effects: a positive direct effect of financial liberalization on bank TFP growth; and a negative indirect effect operating through a higher propensity to systemic banking crisis. The empirical decomposition is based on a sample of 1530 banks operating in 88 countries over the period 1999–2011. We find that the net effect of financial liberalization on bank TFP growth is positive: the direct positive effect outweighs the negative one. An important policy implication flows from these findings.     

Capital account liberalization and income inequality

This article makes both a theoretical and an empirical contribution to the literature on financial liberalization and income inequality. In the first part, we develop a tractable model that features agents with varying investment abilities and a banking sector. There are two possible interventions to liberalize the banking sector: first, a reduction in reserve requirements, and, second, an increase in the amount of foreign funds that can be used to finance domestic loans. Financial liberalization leads to enhanced banking sector efficiency and adjustments in interest rates affecting income of investors and savers, and, therefore, income inequality. Theoretically, the impact of financial liberalization on income inequality is ambiguous. Yet, the model suggests that financial liberalization will improve income distribution in countries where financial depth is high. Our empirical estimates confirm this conditional effect. More precisely, the estimates suggest that capital account liberalization only tends to lower income inequality if the level of financial depth, as measured by private credit over GDP, exceeds 25 percent.     

Financial sector structure and financial crisis burden

We consider an overlapping generations model in the presence of financial intermediation. The paper focuses on the analysis of the consequences of a sudden negative repayments shock on financial intermediation capacity and consequently on the economy as a whole. The model exhibits a property of the ‘chain reaction’ when a single macroeconomic shock can lead to the exhaustion of credit resources and subsequently to the collapse of the banking system. To maintain the capability of the system to recover, a regulatory intervention is needed even in presence of the state guarantees on agents’ deposits in the banks. We compare the results for an intermediated economy with those derived for the market economy and draw some broad conclusions regarding the crisis consequences depending on the financial sector structure. We also compare the model predictions with the stylised facts about the Russian financial crisis of 1998.     

How does banking sector globalization affect banking crisis?

A key feature of financial services liberalization is increasing banking-sector globalization.Using different measures to capture this phenomenon, the present study examines its impact on banking crisis for a dataset of 138 nations spanning the period 1998–2013, while controlling for other banking-industry specific, macroeconomic and external factors. Employing different econometric models and several robustness checks, I find greater banking sector globalization to reduce the occurrence of banking crisis. Moreover, greater bank asset concentration, diversification, credit flows, real interest rates, inflation rates, M2-to-foreign exchange reserves and nominal exchange rate depreciations significantly increase the likelihood of banking crisis, while higher bank profits, real GDP growth, economic development and economic freedom lower such chances. The results are further examined for nations across different levels of economic development and with different degrees of foreign bank penetration. The findings underscore that foreign bank presence provides greater financial stability in the banking industry of host nations.

Macro-Networks: An application to euro area financial accounts

This paper develops a financial network, designated the “Macro-Network”, that depicts the connections between the main financial and non-financial sectors of the economy in the various financial instruments of the euro area. The Macro-Network comprises of linkages across financial and non-financial sectors in each country. These country-level sector networks are then connected by the cross-border links between the individual banking sectors. Using the Macro-Network to simulate financial shocks, we find that the propagation effects depend on the underlying network structure, which evolves over time. After the financial crisis, bilateral linkages contracted sharply, reflecting the surge in counterparty risk and the de-leveraging processes. Nonetheless, our analysis suggests that even after this process, vulnerabilities remained in the euro area financial system, while a more diversified portfolio of cross-border exposures might mitigate the shock effects. We identify sectors which are most relevant for the propagation of financial shocks in the Macro-Network.     

Bank concentration and financial constraints on firm-level investment in Europe

This study examines the effect of bank concentration on financing constraints of non-financial firms in 14 European countries between 1992 and 2005. Using firm-level data we analyze financial constraints with the Euler equation derived from the dynamic investment model. We find that with a highly concentrated banking sector firms are less financially constrained. This result is robust to consideration of firm opacity, firm size, and business cycle. Relaxation of financial constraint while greater for firms in less opaque industries also accrues for firms in more opaque industries. Greater bank concentration is associated with less tight financial constraint during both expansions and recessions. Results overall are consistent with an information-based hypothesis that more market power increases banks’ incentives to produce information on potential borrowers. Findings are robust to consideration of country specific institutional factors.     

Determinants of risk in the banking sector during the European Financial Crisis

Risk assessment in the banking sector has been a prominent topic in the banking literature and has gained attention especially since the recent financial crises. In particular, the European crisis, which was the first since the formation of the Eurozone, underlined a number of significant problems and increased concerns on the tail or crash risk of banks. In the present study, we seek to examine whether information asymmetry, the importance of banks in the financial system and systemic risk play significant roles in the evolution of stock crashes in the banking sector. Information asymmetry is proxied by opacity, the importance of a bank in a financial network is proxied by network centrality, and systemic risk is proxied by clustering. The research framework considers a number of regulatory, reporting and financial market factors that have also been determined to relate to stock crashes and shows that all of the above factors are related to (idiosyncratic) stock crash risk under specific conditions.     

From me to you: Measuring connectedness between Eurozone financial institutions

This paper aims to analyse the tail risk spillover between banks, insurance companies and the shadow banking system in the Eurozone contest. These intra-sectoral interdependencies between financial market participants have contributed to the spread of instability in the financial system. Therefore mapping these links is important for policy-makers to provide supervisory tools and can be a key input into the design of macroprudential policies. For this purpose, we adopt the Tail-Event driven NETwork (TENET) risk model. The TENET is a useful method to map the tail interconnection between the three sectors and to provide systemic risk measures that take into account the “too big to fail” and “too big to interconnected” concepts. The results suggest that each financial sector has a significant impact on the other. By comparing the contribution of each sector, we show that banks are the largest emitters of risk. However, also shadow banking firms are systemic important, given their high level of connection. The work provides a clear view of risk spillovers and interconnection dynamics during the crisis providing a meaningful ranking of the systemic important financial institutions.     

德国利率市场化改革的特点与其金融业发展

利率市场化是指金融机构在货币市场经营融资的利率由市场供求来决定,它包括利率决定、利率传导、利率结构和利率管理的市场化。文章考察了德国利率市场化改革的特点及其对金融业发展的积极影响。德国利率市场化改革分步骤平稳推进。改革后,在全能银行模式下德国金融业没有出现象美、英那样的银行集中倒闭危机;银行贷款在非金融部门融资中仍居于主导地位,而住户部门的金融资产结构发生显著变化;德国的货币政策主要是通过改变银行的流动性来影响金融市场利率,进而间接影响银行信贷政策以及实体经济。     

Decomposing the effects of financial liberalization: Crises vs. growth

We present a new empirical decomposition of the effects of financial liberalization on economic growth and on the incidence of crises. Our empirical estimates show that the direct effect of financial liberalization on growth by far outweighs the indirect effect via a higher propensity to crisis. We also discuss several models of financial liberalization and growth whose predictions are consistent with our empirical findings.     

Credit risk transfer and financial sector stability

In this paper, we study credit risk transfer (CRT) in an economy with endogenous financing (by both banks and non-bank institutions). Our analysis suggests that the incentive of banks to transfer credit risk is aligned with the regulatory objective of improving stability, and so the recent development of credit derivative instruments is to be welcomed. Moreover, we find the transfer of credit risk from banks to non-banks to be more beneficial than CRT within the banking sector. Intuitively, this is because it allows for the shedding of aggregate risk which must otherwise remain within the relatively more fragile banking sector. Therefore, regulators should act to maximize the benefits from CRT by encouraging the development of instruments favorable to the cross-sectoral transfer of aggregate credit risk (including basket credit derivatives such as collateralized debt obligations). Finally, we derive the optimal regulatory stance for banks relative to non-bank financial institutions. We show that a level playing field approach is sub-optimal. Regulatory stances should be set to actively encourage cross-sector CRT, first because of the higher fragility of the banking sector and second to induce banks to incur the costs of CRT which otherwise lead them to undertake an insufficient amount of CRT.     

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.     

Financial Sector transparency and net interest margins: Should the private or public Sector lead financial Sector transparency?

This study examines the effect of private and public sector led financial sector transparency on bank interest margins across eighty-six economies. Using a two-step dynamic system generalized method of moments, least square dummy variables, fixed effects and bootstrap quantile panel models between 2005 and 2016, the findings of the two-step GMM are reported as follows. First, results reveal that financial sector transparency whether led by private or public sector reduces interest margins. Second, while no statistical evidence was found on which of the two (private or public sector led transparency) is more effective in dealing with bank interest margins, public sector-led financial transparency is found to be more consistent in reducing bank interest margins across many more economies. Third, the study shows that the effect of financial sector transparency is visible at lower and middle levels of bank interest margins implying that economies with lower and moderately high bank interest margin level can benefit more from policies targeted at improving transparency in the financial sector. These findings imply that the sampled countries must enact policies and laws that deepen and expand financial sector transparency in order to potentially reduce bank interest margins for the good of banking market participants and society at large.     

中国金融部门杠杆周期分析——基于1998-2018年的数据证明

结合中国经济金融体系发展实践,以银行部门（其他存款性公司）总资产/实收资本作为代理指标分析中国金融部门杠杆率的周期性特征,并对周期形成原因进行探究,对我国金融部门杠杆周期与金融周期的顺周期性进行检验。结果显示：在观测期内,中国金融部门杠杆经历了多个短周期,短周期长度在9～16个季度（约2～4年）不等,并经历了至少1次中周期,中周期时间约为35个季度（约9年）;我国金融部门杠杆周期与国家金融监管政策密切相关;我国金融部门的杠杆周期与金融周期并不必然表现为顺周期性。因此,我国应当更加注重金融监管政策和信贷政策的配合协同,科学反映金融部门杠杆情况,维护金融稳定,防止发生系统性金融风险。
