Capital regulation,deposit insurance and bank risk: International evidence from normal and crisis periods

In this paper, we examine the impact of capital regulation on bank risk and the moderating role of deposit insurance on the relationship between capital regulation and bank risk during both normal and crisis periods. Using an international sample of banks from 111 countries, our results show that stringent capital regulation reduces bank default risk, in general, during normal growth period, and this effect is not conditioned by the existence of explicit deposit insurance. Further, stringent capital regulation in place during the pre-crisis period reduces bank default risk during the crisis period, and this effect is stronger for countries with explicit deposit insurance during the pre-crisis period. These results have important policy implications to design the optimal bank regulations.     

Reforms in Thai bank governance: The aftermath of the Asian financial crisis

This paper provides an empirical analysis of Thailand's bank governance reforms after the 1997 Asian financial crisis and then examines the stock market's response. Unlike the pre-crisis period, we find that the bank sector returns (or return volatilities) have become more Granger causal to the overall stock market in the post-crisis period. Announcements of bank governance reforms are also generally associated with significant change in bank sector returns. This adds to the proposition that improved bank governance is related to improved bank performance as measured by their bank stock returns.     

The non-monotonic impact of bank size on their default swap spreads: Cross-country evidence

This paper studies the drivers of bank's credit default swap (CDS) spread, taken as a measure of credit risk, by considering the impact of housing market along with a number of bank level determinants, such as regulatory capital, leverage, size, liquidity, asset quality and operations income ratio. We build upon a unique dataset consisting of 115 banks (during pre- and post-crisis periods) headquartered in 30 countries from both developed and emerging countries. Results suggest that CDS spread is driven by asset quality, liquidity and operations income ratio, while bank size is found to have a non-monotonic impact on CDS spread. If the bank is small, an increase in size reduces the average credit risk. If the bank is large enough, an increase in size raises the latter. From our results we derive the level of bank size that minimizes the CDS spreads. Financial institutions growing beyond this threshold are subject to higher credit risk, implying that smaller and medium sized banks are safer than large banks. When considering the estimates in the periods before and after the 2007 crisis, we further find a different extreme point of bank size in the former (approximately 1642 billion Euros) relative to a significantly lower level of optimal bank size (around 70 billion) in the post-crisis period, implying too-big-to-fail and too-big-to-save in the pre-crisis regime.     

Do bank bailouts affect the provision of trade credit?

We document that borrowers of banks that received capital support under TARP/CPP significantly increased their quarterly provision of trade credit (accounts receivable) during the crisis by 5.2%, while borrowers of other banks did not. The effect is strongest in 2008Q4, and larger for pre-crisis riskier, growth-oriented and bank-dependent firms and for firms that borrow from pre-crisis smaller, less profitable and better capitalized CPP banks. Our difference-in-differences analysis shows that the effect is caused by CPP and not by heterogeneity between firms, banks and time periods. Our study provides novel evidence that suggests a beneficial multiplier effect of bank bailouts.     

How Banks' Value-at-Risk Disclosures Predict their Total and Priced Risk: Effects of Bank Technical Sophistication and Learning over Time

Using a sample of eight large commercial banks from 1994 to 2000, Jorion (2002) finds that banks' VaR disclosures for their trading portfolios predict trading income variability. We extend Jorion's findings using a larger sample of 17 banks from 1997 to 2002 reporting trading VaRs under FRR No. 48 (1997). We find that banks' trading VaRs have predictive power for trading income variability that increases with bank technical sophistication and over time. We find that banks' trading VaRs have predictive power for a bank-wide measure of total risk, return variability, and for two bank-wide measures of priced risk, beta and realized returns.

Bank funding structures and risk: Evidence from the global financial crisis

This paper analyzes the evolution of bank funding structures in the run up to the global financial crisis and studies the implications for financial stability, exploiting a bank-level dataset that covers about 11,000 banks in the U.S. and Europe during 2001–09. The results show that banks with weaker structural liquidity and higher leverage in the pre-crisis period were more likely to fail afterward. The likelihood of bank failure also increases with pre-crisis bank risk-taking. In the cross-section, the smaller domestically-oriented banks were relatively more vulnerable to liquidity risk, while the large cross-border (Global) banks were more vulnerable to solvency risk due to excessive leverage. In fact, a 3.5 percentage point increase in the pre-crisis capital buffers of Global banks would have caused a 48 percentage point in their probability of failure during the crisis. The results support the proposed Basel III regulations on structural liquidity and leverage, but suggest that emphasis should be placed on the latter, particularly for the systemically-important institutions. Macroeconomic and monetary conditions are also shown to be related with the likelihood of bank failure, providing a case for the introduction of a macro-prudential approach to banking regulation.     

The performance of precious-metal mutual funds: Does uncertainty matter?

We studied the relative risk-adjusted returns and downside risk performance of precious-metal mutual funds (PMFs) in different uncertainty periods (pre-crisis, crisis and post-crisis) using propensity score matching techniques and difference-in-differences matching regression. For a sample of PMFs and global corporate funds quoted in USD over the period January 2005 to June 2015, we found that the relative performance of PMFs differed across uncertainty periods. Thus, they performed similarly to corporate funds in the pre-crisis period, they outperformed corporate funds regarding risk-adjusted returns but underperformed in terms of downside risk in the crisis period and they displayed a similar risk-return performance to corporate funds in the post-crisis period. Difference-in-difference estimates indicate that a shift from low to high uncertainty had a positive impact on risk-adjusted returns for PMFs, whereas this advantage dissipated when uncertainty was reduced. However, fluctuations in uncertainty had mixed effects on the relative downside risk associated with PMFs. This evidence has implications for investors who seek to gain exposure to precious metals using PMFs.     

The influence of accounting enforcement on earnings quality of banks: Implications of bank regulation and the global financial crisis

We study the effects of country-level accounting enforcement on earnings quality of banks and whether bank regulation substitutes or complements the effect of accounting enforcement on bank earnings quality. We also examine whether the influence of accounting enforcement on bank earnings quality changed after the global financial crisis. Using a sample of listed banks from 40 countries between 2001 and 2014, and abnormal loan loss provisions (ALLP) as our main proxy for earnings quality, we document a consistent and strong association between accounting enforcement and bank earnings quality. More specifically, an increase in accounting enforcement decreases the level of ALLP and decreases the propensity to manage earnings to avoid losses. Furthermore, we provide empirical evidence that bank regulation complements the effect of accounting enforcement on bank earnings quality. Finally, unlike in the pre-crisis period, we find a positive association between accounting enforcement and income-decreasing ALLP in the post-crisis period, which indicates that stronger accounting enforcement is associated with more conservative earnings and higher loan loss reserves. Overall, our results indicate that accounting enforcement reduces opportunistic earnings management.     

Do banks overstate their Value-at-Risk?

This paper is the first empirical study of banks’ risk management systems based on non-anonymous daily Value-at-Risk (VaR) and profit-and-loss data. Using actual data from the six largest Canadian commercial banks, we uncover evidence that banks exhibit a systematic excess of conservatism in their VaR estimates. The data used in this paper have been extracted from the banks’ annual reports using an innovative Matlab-based data extraction method. Out of the 7354 trading days analyzed in this study, there are only two exceptions, i.e. days when the actual loss exceeds the disclosed VaR, whereas the expected number of exceptions with a 99% VaR is 74. For each sample bank, we extract from historical VaRs a risk-overstatement coefficient, ranging between 19 and 79%. We attribute VaR overstatement to several factors, including extreme cautiousness and underestimation of diversification effects when aggregating VaRs across business lines and/or risk categories. We also discuss the economic and social cost of reporting inflated VaRs.     

The impact of state ownership on performance differences in privately-owned versus state-owned banks: An international comparison

This paper examines how government ownership and government involvement in a country’s banking system affect bank performance from 1989 through 2004. Our study uncovers an interesting pattern of changing performance differences between state-owned and privately-owned banks around the Asian financial crisis. We find that state-owned banks operated less profitably, held less core capital, and had greater credit risk than privately-owned banks prior to 2001, and the performance differences are more significant in those countries with greater government involvement and political corruption in the banking system. In addition, from 1997 to 2000, the 4-year period after the beginning of the Asian financial crisis, the deterioration in the cash flow returns, core capital, and credit quality of state-owned banks was significantly greater than that of privately-owned banks, especially for the countries that were hardest hit by the Asian crisis. However, state-owned banks closed the gap with privately-owned banks on cash flow returns, core capital, and nonperforming loans in the post-crisis period of 2001–2004. Our findings can best be explained by Shleifer and Vishny’s [Shleifer, A., Vishny, R.W., 1997. A survey of corporate governance. J. Finance 52, 737–783] corporate governance theory on state ownership of firms and Kane’s [Kane, E.J., 2000. Capital movement, banking insolvency, and silent runs in the Asian financial crisis. Pacific-Basin Finance J. 8, 153–175] life-cycle model of a regulation-induced banking crisis.     

Dynamic technical and allocative efficiencies in European banking

This paper examines the performance of European banks during the pre-crisis and post-crisis periods, both in terms of technical and allocative efficiencies. We use an innovative Bayesian dynamic frontier model that: (1) distinguishes between short-run and long-run performance; and (2) provides impulse response functions to examine the dynamic effect of shocks in technical and allocative inefficiencies. Based on a rich sample of European banks, we show that while there was a drop in efficiency for most countries following the crisis, the long-run results suggest improvement both in terms of technical and allocative efficiencies. The impulse response functions also show that in the case of shocks in the system, banks seem to revert back to these long-run allocative efficiency scores. We discuss the results in terms of the current financial crisis and provide interesting implications for the European banking industry. We also discuss the determinants of technical and allocative efficiencies. (We would like to thank Professor Allen N. Berger and Professor Andy Mullineux for their valuable comments on the early version of this paper.)     

Endogenous crisis dating and contagion using smooth transition structural GARCH

Detecting contagion during financial crises requires the demarcation of crisis periods. We develop a method for endogenously dating both the start and finish of crises, along with measuring contagion effects. Identification is achieved by coupling smooth transition functions with structural GARCH. In an application to US equity, bond and REIT returns for 2001–2010, we identify four phases; a pre-crisis period to July 2007, two phases of crisis up to and following October 2008, and a post-crisis phase from mid-May 2009. We detect significant contagion during the crisis and find evidence that the post-crisis period has not returned to pre-crisis relations.     

Income smoothing among European systemic and non-systemic banks

There is scant research on the financial reporting behaviour of global systemically-important banks (G-SIBs) and non-global systemically-important banks (non-G-SIBs). We examine the link between financial reporting and financial system stability given the understanding that income smoothing is a stability mechanism for banks. We empirically examine whether the way G-SIBs use loan loss provisions (LLPs) to smooth income differ compared to non-G-SIBs and the incentive to do so. We examine 231 European banks and find that income smoothing is pronounced among G-SIBs in the post-crisis period and pronounced among non-G-SIBs in the pre-crisis period. Also, G-SIBs exhibit greater income smoothing when they: (i) have substantial non-performing loans, (ii) are more profitable and meet/exceed minimum regulatory capital ratios (iii) engage in forward-looking loan-loss provisioning and during recessionary periods. The implication of our findings is that capital regulation and abnormal economic fluctuations create incentives for systemic banks to use accounting numbers (loan loss provisions) to smooth income, which also align with the financial system stability objective of bank regulators. Our findings are useful to accounting standard setters in their evaluation of the role of reported accounting numbers for financial system stability, given the current regulatory environment in Europe which focuses on systemic banks.     

Institutions and Deposit Insurance: Empirical Evidence

Do banks’ responses to changes in deposit insurance vary across countries even if the countries have comparable institutions? If so, by how much? Using data on the financial performance of large banks in 15 financially and economically developed countries, we find that where deposit insurance has an effect, it is large and varies depending on the level of economic freedom, rule of law and corruption in the bank’s home country. As in prior papers, we show that during stable economic periods, increases in deposit insurance are associated with higher bank risk, both problem loans and leverage. In most, but not all, cases stronger institutions temper these effects. The institutions’ effects are substantial. For example, average changes in the rule of law double the impact of a change in deposit insurance on bank leverage. We contribute to the substantial literature in this area by showing that the institutional effects are significant even across a set of countries with comparable institutions; by conducting a careful calibration of the economic significance of the effects; by providing evidence that during stable periods changes in deposit insurance only affect bank risk and not other measures of performance; and finally by showing that the effects of both deposit insurance and institutions vary across stable and crisis economic periods. The stable period results are consistent with the moral hazard effects of deposit insurance, while the crisis period results are consistent with endogeneity concerns that poor bank performance could drive changes in regulations.     

Effects of international institutional factors on earnings quality of banks

We examine the relation between legal, extra-legal and political institutional factors and earnings quality of banks across countries. We predict that earnings quality is higher in countries with legal, extra-legal and political systems that reduce the consumption of private control benefits by insiders and afford outside investors greater protection. Using a sample of banks from 35 countries during the pre-crisis period from 1993 to 2006, we find that all five measures of earnings quality studied are higher in countries with stronger legal, extra-legal and political institutional structures. We also find that banks in countries with stronger institutions are less likely to report losses, have lower loan loss provisions, and higher balance sheet strength during the 2007–2009 crisis period. Our findings highlight the implications of country level institutional factors for financial reporting quality and are relevant to bank regulators who are considering additional regulations on bank financial reporting.     

Market power in CEE banking sectors and the impact of the global financial crisis

The aim of this study is to undertake an up-to-date assessment of market power in Central and Eastern European banking markets and explore how the global financial crisis has affected market power and what has been the impact of foreign ownership. Three main results emerge. First, while there is some convergence in country-level market power during the pre-crisis period, the onset of the global crisis has put an end to this process. Second, bank-level market power appears to vary significantly with respect to ownership characteristics. Third, asset quality and capitalization affect differently the margins in the pre-crisis and the crisis periods. While in the pre-crisis period the impacts are similar for all banks regardless of ownership status, in the crisis period non-performing loans have a negative effect and capitalization a positive effect only for domestically-owned banks.     

Foreign banks and credit stability in Central and Eastern Europe. A panel data analysis

We examine whether foreign and domestic banks in Central and Eastern Europe react differently to business cycles and banking crises. Our panel dataset comprises data of more than 250 banks for the period 1993–2000, with information on bank ownership and mode of entry. During crisis periods domestic banks contracted their credit base, whereas greenfield foreign banks did not. Also, home country conditions matter for foreign bank growth, as there is a significant negative relationship between home country economic growth and host country credit by greenfields. Finally, greenfield foreign banks’ credit growth is influenced by the health of the parent bank.     

Religiosity and bank earnings management: Revisiting international evidence

The modernization theory forecasts a sharp declining effect of institutionalized religion on human behavior owing to the extensive economic development. However, this prediction is rejected and proved that religious values and beliefs have a pervasive influence on individual conduct. Based on this salient evidence, we examine the influence of religious social norms on bank earnings management behavior with regard to ongoing economic development. We use 20,715 bank-year observations from 1318 listed banks of eight geographical regions. We, further, employ an updated dataset of 2007–2021 to resemble the economic prosperity time period. Our study discards the prediction of the modernization theory and reveals that banks located in countries with high religiosity are less likely to manage their reported earnings. While comparing conventional banks with Islamic ones, conventional banks are found to be less prone to the earnings management practice than that of their Islamic counterparts. We also find religiosity to have a greater magnitude of effect on the accounting manipulation in the crisis period than in the post-crisis one. The cross-regional differences in religious values bring differential effects on this unethical practice. Our results are robust with the alternative measures of earnings management and alternative model specifications.     

How using derivatives affects bank stability in emerging countries? Evidence from the recent financial crisis

Based on banks exclusively from emerging countries over the whole period 2003–2011, this paper aims to investigate whether the use of derivative instruments are responsible in the amplification of the recent and global financial crisis. To do that, we measure the effect of derivatives use on stability of banks from emerging countries during normal period “the pre-crisis period”, 2003–2006, and turbulent period “the crisis and post-crisis period”, 2007–2011. We use the Generalized Methods of Moments (GMM) estimator technique developed by Blundell and Bond to estimate our regressions.The main findings show that contrarily to forwards and swaps – which are not disruptive factors – futures and especially options, weaken the stability of banks from emerging countries. The major conclusion is that only options and futures can be considered as risky derivatives and partly responsible in the intensification of the last financial crisis.
