The relationship between banking market competition and risk-taking: Do size and capitalization matter?

This paper addresses the effects of bank competition on the risk-taking behaviors of banks in 10 Latin American countries between 2003 and 2008. We conduct our empirical approach in two steps. First, we estimate the Boone indicator, which is a measure of competition. We then regress this measure and other explanatory variables on the banking “stability inefficiency” derived simultaneously from the estimation of a stability stochastic frontier. Unlike previous findings, this paper concludes that competition affects risk-taking behavior in a non-linear way as both high and low competition levels enhance financial stability, while we find the opposite effect for average competition. In addition, bank size and capitalization are essential factors in explaining this relationship. On the one hand, the larger a bank is, the more it benefits from competition. On the other hand, a greater capital ratio is advantageous for banks that operate in collusive markets, while capitalization only enhances the stability of larger banks under high and average competition. These results are of extreme importance when considering bank regulations, especially in light of the recent turmoil in the global financial markets.     

The ‘competition–stability/fragility’ nexus: A comparative analysis of Islamic and conventional banks

The ‘competition–stability/fragility’ nexus is one of the more debated issues in the banking literature. However, while there is ample evidence concerning the relationship between competition and stability/fragility in different countries and regions, no prior study investigates this in the context of Islamic and conventional banks. We do this using data on both types of banks drawn from 16 developing economies over the period 2000–12. We measure the lack of competition using the Lerner index, and stability using both accounting-based measures, comprising the Z-score and the nonperforming loan ratio, and market-based measures, including Merton's distance to default. We employ panel vector autoregression and two-stage quantile regression to estimate the relationship. Our results lend support to the competition–fragility hypothesis in both Islamic and conventional banks. We also find the magnitude of the market power effect on stability is greater for conventional banks than Islamic banks. Lastly, banks in the median quantile of stability have a greater ability to reduce credit risk through gaining market power than banks in the lower and upper quantiles.     

Bank Competition: Measurement,Decision‐Making,and Risk‐Taking

This paper investigates whether greater competition increases or decreases individual bank and banking system risk. Using a new text‐based measure of competition, and an instrumental variables analysis that exploits exogenous variation in bank deregulation, we provide robust evidence that greater competition increases both individual bank risk and a bank's contribution to system‐wide risk. Specifically, we find that higher competition is associated with lower underwriting standards, less timely loan loss recognition, and a shift toward noninterest revenue. Further, we find that higher competition is associated with higher stand‐alone risk of individual banks, greater sensitivity of a bank's downside equity risk to system‐wide distress, and a greater contribution by individual banks to downside risk of the banking sector.     

The interplay between quantitative easing,risk and competition: The case of Japanese banking

The Japanese economy is infamous for the magnitude of bank nonperforming loans that have originated back in the 1990s, whereas they are still causing controversies. Japan is also known for an extended quantitative easing programme of unprecedented scale. Yet the links between risk‐taking activities, quantitative easing and bank competition are largely unexplored. This paper employs, for the first time, the Boone indicator to measure bank competition in Japan to examine these underlying linkages. Given the scale of nonperforming loans, we explicitly measure bank risk‐taking based on a new data set of bankrupt and restructured loans. The dynamic panel threshold and panel Vector Autoregression analyses show that enhancing quantitative easing and competition would reduce bankrupt and restructured loans, but it would negatively affect financial stability. Given the recent adoption of negative rates in January 2016 by the Bank of Japan, our study provides new insights as clearly there is a trade‐off between quantitative easing and financial stability beyond a certain threshold. Caution, therefore, regarding further scaling up quantitative easing is warranted.     

Competition,Financial Intermediation,and Riskiness of Banks: Evidence from the Asia-Pacific Region

From a sample of commercial banks in the Asia-Pacific region over the 1994–2009 period, this study highlights that banks in less competitive markets exhibit lower loan growth and higher instability. Such instability is further followed by a decline in deposit growth, suggesting that Asian banks are also subject to indirect market discipline mechanisms through bank competition. This study therefore sheds light on the importance of enhancing bank competition to overcome bank risk and strengthen financial intermediation. Likewise, this study advocates the importance of strengthening market discipline to reduce bank riskiness regardless of the degree of competition in the banking industry.     

Geographic Deregulation and Competition in the U.S. Banking Industry

We examine the effects of geographic deregulation on state‐level competition in U.S. banking markets over the period 1976‐2005. The empirical results confirm that the U.S. banks in general operated under monopolistic competition during the period examined. After partitioning the sample based on bank size we find that the market competition for large banks in Delaware, Oregon, and Rhode Island can be characterized as monopolistic while small banks in Arizona and Massachusetts seem to have operated under the conditions of perfect competition. The removal of geographic restrictions appears to have very limited and non‐uniform effect on state‐level competitive conduct. There is some evidence that the U.S. banking industry might have actually experienced a less competitive behavior in recent years due to increased market power of larger banks.     

存款保险、市场竞争与银行经营稳健性

本文基于银行存款市场空间竞争模型,探讨存款保险制度的实施效果和福利效应,及其与市场竞争政策的交互作用。研究表明,政府隐性担保尽管能够保障存款人利益,但会降低存款人对银行经营稳健性的要求,使得银行追求高风险高收益资产从而降低经营稳健性;而市场化的存款保险制度通过费率与风险挂钩的激励机制,能够有效提升银行经营稳健性,同时避免过高政策成本负担,实现较高的社会福利水平。随着市场竞争强化,引入风险差别费率保险制度,在提升银行经营稳健性和增进社会福利方面的效果逐渐增强。模型分析表明,当长期允许机构自由进出市场时,政府强化竞争政策短期可能降低银行的经营稳健性,但长期内高风险银行逐渐退出市场而更有效率的低风险银行进入市场,这种柔性市场退出机制使得银行业整体经营稳健性增强。因此,在金融市场中强化竞争政策,推行并完善当前市场化的风险差别费率存款保险制度,长期内有助于在保护存款人利益的同时,提升银行稳健性和社会福利。     

Competition,concentration and risk taking in Banking sector of MENA countries

This paper tests the relationship between competition and bank stability for 356 banks operating in the Middle East North Africa (MENA) countries during the period 2005–2012. Our results show that for the overall sample, a U-shaped relationship between competition and banks’ risk taking for MENA banks. The negative linear relationship between Z-Score and H-statistics in Gulf countries shows that an increase in competition leads to a reduction in the level of financial stability. In the case of other non-Gulf countries, the increase of competition in uncompetitive markets can lead to an increase in stability. The results confirm the importance of the market structure as an explanatory factor for financial stability, but also indicate that concentration is not associated with uncompetitive markets.     

Performance of the Life Insurance Industry Under Pressure: Efficiency,Competition, and Consolidation

This article investigates efficiency and competition in the Dutch life insurance market by estimating unused scale economies and measuring efficiency‐market share dynamics during 1995–2010. Large unused scale economies exist for small‐ and medium‐sized life insurers, indicating that further consolidation would reduce costs. Over time average scale economies decrease but substantial differences between small and large insurers remain. A direct measure of competition confirms that competitive pressure is lower than in other markets. We do not observe any impact of increased competition from banks, the so‐called investment policy crisis or the credit crisis, apart from lower returns in 2008.     

银行价格竞争、融资约束与企业研发投资——基于“中介效应”模型的实证研究

近年来我国利率市场化改革积极推进,实体经济发展积极向创新驱动转型,一个亟须研究厘清的关键问题是,银行业竞争如何驱动企业创新活动？本文关注银行价格竞争对企业创新的影响,以2013—2018年沪深两市的上市企业为样本,采用“中介效应”因果分析模型,实证检验了银行价格竞争对企业研发投资的影响,并识别出以融资约束为中介渠道的作用机制。研究发现,银行价格竞争不仅会提高银行的风险容忍度,直接增加R&D投资的信贷供给意愿,而且还会通过降低贷款价格和增加贷款可得性来缓解企业整体的融资约束,间接促进企业创新活动。这一机制在解除贷款利率管制之后以及在民营企业层面体现得更加明显。本文的研究结果对于深化金融市场化改革、改善金融服务实体经济效果以及实施经济创新驱动发展战略,具有明确的政策启示。     

Bank governance,regulation, supervision,and risk reporting: Evidence from operational risk disclosures in European banks

This paper investigates the direct and joint effects of bank governance, regulation, and supervision on the quality of risk reporting in the banking industry, as proxied for by operational risk disclosure (ORD) quality in European banks. After controlling for the endogeneity between bank stability and risk reporting quality, we find that banks having a higher proportion of outside board directors, lower executive ownership, concentrated outside non-governmental ownership, and more active audit committee, and operating under regulations promoting bank competition (i.e., less stringent entry to banking requirements) provide ORD of higher quality. In addition, we find that the contribution of bank supervisors to the enhancement of ORD quality depends on the ownership structure of the bank. Specifically, powerful and independent bank supervisors mitigate the incentives for entrenched bank executives to withhold voluntary ORD. Moreover, bank supervisors and largest shareholders perform substitutive roles in monitoring the bank management's compliance with mandatory ORD requirements. For the sake of enhancing risk reporting quality in banks, our findings recommend sustaining board independence, enhancing audit committee activity, easing entry to banking requirements, and promoting a more proactive role for bank supervisors.     

Securitization,competition and monitoring

We analyze the impact of loan securitization on competition in the loan market. Using a dynamic loan market competition model where borrowers face both exogenous and endogenous costs to switch between banks, we uncover a competition softening effect of securitization that allows banks to extract rents in the primary loan market. By reducing monitoring incentives, securitization mitigates winner’s curse effects in future stages of competition thereby decreasing ex ante competition for initial market share. Due to this competition softening effect, securitization can adversely affect loan market efficiency while leading to higher equilibrium profits for banks. This effect is driven by primary loan market competition, not by the exploitation of informational asymmetries in the secondary market for loans. We also argue that banks can use securitization as a strategic response to an increase in competition, as a tool to signal a reduction in monitoring intensity for the sole purpose of softening ex ante competition. Our result suggests that securitization reforms focusing exclusively on informational asymmetries in markets for securitized products may overlook competitive conditions in the primary market.     

Explaining banking stability in Sub-Saharan Africa

The study examined banking stability in Sub-Saharan Africa. The results reveal that banking spread (Net Interest Margin – NIM) is the main determinant of stability and the major means to achieve stability during crises periods. We however find the existence of a threshold effect in NIM.Crises in the banking sector consistently showed to reduce stability. While the results show that high percentage of foreign banks reduce stability, we find foreign banks help stabilize the banking sector in periods of crises. The results show that diversification could also have a positive impact on stability (Z-score) even though this relationship was not robust enough. The results also largely support the competition-fragility view. Particularly, we find that less competition during crises periods can help improve stability. Again, we find evidence for both concentration-stability and concentration-fragility hypotheses depending on the stability measure used. We however find that when large banks in concentrated markets are well regulated, stability could be improved. Weak regulatory environment reduces stability (Z-score) directly and matters during crises periods. Our results are robust to the use of different indicators of stability and estimation methods.     

银行竞争提高了企业投资水平和资源配置效率吗？——基于分支机构空间分布的研究

银行贷款是我国企业融资的重要方式,在企业生产经营中发挥着举足轻重的作用。2006年和2009年,我国先后两次放松了商业银行分支机构市场准入规制,银行分支机构空间分布发生了较大变化,银行竞争水平和服务实体经济能力明显提升。本文利用2001-2012年国家统计局工业企业数据,以企业周边银行分支机构的数量衡量银行竞争水平,研究银行竞争对企业投资的影响。研究发现,银行分支机构数量的增加显著提高了企业投资水平和投资效率。进一步研究表明,银行分支机构数量增加对企业投资效率的提升作用主要表现在投资不足的企业和非国有企业中,企业融资约束降低和代理冲突减弱是银行竞争提高企业投资效率的主要原因。本研究拓展了银行竞争以及企业投资和资源配置效率的相关文献,对供给侧结构性改革和银行业高质量发展具有启示意义。     

The role of strategic interactions in risk-taking behavior: A study from asset growth perspective

This study uses panel data on Vietnamese commercial banks from 2008 to 2018 in order to investigate the role of strategic interactions in determining bank risk-taking behavior by considering bank asset growth. The results suggest that aggressive competition is less favorable for banks striving for stability and that a high value of competitive strategy measure (as a proxy for strategic interactions) encourages risk-taking incentives. We also find that the distributional effects of strategic interaction on bank risk-taking because of asset growth reveal that the uncertainty in strategic-interaction-driven profits diminishes in banks with higher growth. This finding is consistent with the idea that when competition becomes more aggressive, bank restructuring should focus on increasing total assets by merging and acquiring small- and medium-sized banks to stabilize the banking sector. Furthermore, the results demonstrate that banks with low leverage or under regulatory pressure engage in more risk-taking. Therefore, policymakers may not implement a tighter capital requirement that contributes to a heightened level of risk. The results are robust to alternative measures of risk-taking and monetary policy stance as well as different econometric specifications.     

Are Competitive Banking Systems More Stable?

Using the Panzar and Rosse H-statistic as a measure of competition in 45 countries, we find that more competitive banking systems are less prone to experience a systemic crisis and exhibit increased time to crisis. This result holds even when we control for banking system concentration, which is associated with higher probability of a crisis and shorter time to crisis. Our results indicate that competition and concentration capture different characteristics of banking systems, meaning that concentration is an inappropriate proxy for competition. The findings suggest that policies promoting competition among banks, if well executed, have the potential to improve systemic stability.     

How Does Cross‐Border Activity Affect EU Banking Markets?

Cross‐border activity in the EU is widely viewed as a necessary condition for the implementation of a single banking market and therefore as a positive factor for the enhancement of competition and cost performance in the region. In this paper, we analyse the relevance of this view by investigating whether cross‐border activity really promotes competition and cost efficiency in EU banking markets. We also consider the potential role of a bank's mode of entry by comparing existing domestic banks that foreign banks take over (mergers and acquisitions) with new branches created by foreign banks, often through subsidiaries (greenfield operations). We consider the impact of cross‐border banks on cost efficiency (measured by the stochastic frontier approach), profitability (assessed through return on assets) and competition (measured by the Lerner index). We find that greenfield banks enhance cost efficiency and competition, while mergers and acquisitions hamper competition and cost efficiency. Therefore, our results suggest that EU authorities should promote only greenfield banks rather than all cross‐border entries.     

Deposit market competition,wholesale funding,and bank risk

Empirical research on the effect of bank competition on bank risk has so far produced very inconclusive results. In this paper we revisit this long-standing debate and propose a new empirical approach that is concentrated on the relationship between deposit market competition and bank risk. This approach closely follows the traditional theoretical views of the competition and risk relationship and is focused on testing the classical moral hazard problem of the bank: deposit market competition raises the optimal risk choice of the bank by raising the costs of bank liabilities. Since banks can substitute between retail and wholesale funding, we relate deposit market competition to wholesale market conditions and examine their joint effect on the risk of bank assets. The analysis is based on a unique, comprehensive dataset, which combines retail deposit rate data with data on bank characteristics and data on local deposit market features for a sample of 589 US banks. Our results support the notion of a risk-enhancing effect of deposit market competition.     

特许权价值、市场结构与银行风险承担

银行业的风险程度关系到整个经济体的稳定与发展,控制风险是银行经营的重要目标之一。目前对银行风险承担的研究主要从特许权价值和市场竞争的角度分别展开分析。本文以156家中国商业银行为研究对象,同时分析了银行特许权价值、市场竞争程度对银行风险的影响。通过实证分析,我们发现目前影响我国商业银行特许权价值的因素主要来自银行因素而非市场因素;在没有控制内生性的前提下,发现银行特许权价值有效地约束了银行风险,而市场竞争的加剧增加了银行风险行为;在控制银行风险和特许权价值内生性后,发现特许权价值对中国商业银行风险的约束效应基本不存在。因此,要维持银行业的稳定,需要规范银行的竞争行为,提高特许权价值的风险约束效应。     

Competition in dual markets: Implications for banking system stability

This paper investigates whether Islamic and conventional banks' stability is differently impacted by competition in dual markets where the two bank types operate alongside each other. Using a sample of 123 Islamic and 647 conventional banks from 29 countries for a period between 2010 and 2018, we find robust evidence that competition erodes the stability of conventional banks only. The stability of Islamic banks is not impacted specifically where religion is more prevalent. Focusing more deeply on religiosity and the institutional environment, such as the ease of doing business and economic freedom, we also find that such factors matter in differently shaping the competition-fragility nexus for the two types of banks.
