Do the business cycle and revenue diversification matter for banks’ capital buffer and credit risk: Evidence from ASEAN banks

We examine the association of the business cycle and revenue diversification with the banks’ capital buffer and credit risk for a sample of banks from the Association of Southeast Asian Nations (ASEAN) region from 1998 to 2018, using 2847 banking firm–year observations. We find that ASEAN region banks react anticyclically in adjusting their capital buffer levels and credit risk. We find revenue diversification benefits and that banks, through revenue diversification, can reduce their credit risk while achieving capital savings when confronting economic downturns. Our results offer support for the Basel III accord. However, the relations revealed are somewhat moderated by the regulatory quality, competition, and phase of the business cycle encountered by ASEAN region banks.     

Income diversification and risk: Does ownership matter? An empirical examination of Indian banks

We examine the impact of ownership on income diversification and risk for Indian banks over the period 2001–2009. We investigate both the determinants of non-interest income and the impact of diversification on various profitability and insolvency risk measures for public sector, private domestic, and foreign banks. We document that ownership does matter in the pursuit of non-interest income. Relative to private domestic banks, public sector banks earn significantly less fee-income, while foreign banks report higher fee income. Public sector banks with higher levels of governmental ownership are significantly less likely to pursue non-interest income sources. Fee-based income significantly reduces risk, measured by profitability variables, for public sector banks. Default risk is also reduced for these banks. From a regulatory perspective, it appears that diversification benefits India’s public sector banks. Our research has implications for the changes in the risk profile for banks in emerging banking markets pursuing non-interest revenue sources.     

The effects of loan portfolio concentration on Brazilian banks’ return and risk

This paper tests whether diversification of the credit portfolio at the bank level leads to better performance and lower risk. We employ a new high frequency (monthly) panel data for the Brazilian banking system with information at the bank level for loans by economic sector. We find that loan portfolio concentration increases returns and also reduces default risk; the impact of concentration on bank’s return is decreasing on bank’s risk; there are significant size effects; foreign and state-owned banks seem to be less affected by the degree of diversification. An important additional finding is that there is an increasing concentration trend after the breakout of the recent international financial crisis, specially after the failure of Lehman Brothers.     

In Banking,Is Small Beautiful?

The state‐led resolution of the 2007‐2009 financial crisis has proven to be costly. Calls are being heard in Belgium, the Netherlands and Switzerland to cap the size of domestic banks. Is small beautiful? In this policy paper, we first match bailing out cost data to the relative size of banks for a sample of 14 countries and 29 banks. An important observation is that some countries with relatively small banks faced large bailout cost when correlated systemic risk affected many banks. Secondly, we call to the attention that capping the size of banks can have an unintended effect: a lack of credit risk diversification. Risk diversification is needed to reduce the costs of financial distress, which are quite significant in the banking industry. If reducing public bail out costs is the right objective, capping the size of banks is not the best tool. So as to keep large banks that provide highly skilled employment opportunities in a services economy, we discuss four policy options that help to ensure financial stability: independence and accountability of bank supervisors, prompt corrective action mechanisms, burden sharing across countries, and an end to the too‐big‐to‐fail doctrine.     

Economic value,competition and financial distress in the European banking system

In this paper we examine the impact of a large number of factors at the bank level (liquidity and credit risks, asset size, income diversification and market power), at the industry level (banking concentration) and macro-level (real GDP growth) on bank financial distress using an unbalanced panel of 308 European commercial banks between 1996 and 2009. The observations falling below a given threshold of the empirical distribution of the Shareholder Value Ratio proxy bank financial distress. We employ a panel probit regression and, given the presence of overlapping data giving rise to residual autocorrelation, we use the Bertschek and Lechner (1998) robust estimator of the covariance matrix of parameters. We show that credit risk, liquidity risk and bank market power are the most influential determinants of distressed Shareholder Value Ratio. Finally we evaluate the model out-sample forecasting performance over the 2008–2009 crisis period.     

我国商业银行经营投资银行业务对风险影响的实证研究

本文以2009-2018年19家商业银行为研究对象,运用波动性分析、相关性分析及面板数据回归分析方法,考察了经营投资银行业务对银行风险的影响。研究结果表明,投资银行收入无明显周期性趋势,波动性明显高于利息净收入,经营投资银行业务会加剧银行业收入的不确定性,但由于收入占比较小,投资银行业务并非造成我国银行业收入波动的主要因素。多数银行的投资银行收入与利息净收入表现为正相关性,银行难以通过经营投资银行业务实现风险分散目的。投资银行业务对银行风险影响的回归结果较为显著,随着投资银行收入在银行收入结构中的权重越来越大,银行多元化收入程度随之加深,银行风险也随之下降。     

The impacts of risk-taking behaviour and competition on technical efficiency: Evidence from the Chinese banking industry

This paper tests the impact of risk and competition on efficiency in the Chinese banking industry over the period 2003–2013. Comprehensive types of risk-taking behaviour are considered including credit risk, liquidity risk, capital risk, and insolvency risk. Competition is measured by the Lerner index. The results are cross-checked using an alternative econometric technique as well as an alternative competition indicator. The findings show that the technical and pure technical efficiencies of Chinese commercial banks are significantly and negatively affected by liquidity risk. They further show that greater competition precedes declines in technical and pure technical efficiencies of Chinese commercial banks. The results suggest that Chinese bank efficiency is significantly affected by bank diversification, banking sector development, stock market development, inflation and GDP growth rate. The findings also indicate that, compared to state-owned commercial banks, joint-stock commercial banks and city commercial banks have lower technical and pure technical efficiencies.     

Credit risk transfer and contagion

Some have argued that recent increases in credit risk transfer are desirable because they improve the diversification of risk. Others have suggested that they may be undesirable if they increase the risk of financial crises. Using a model with banking and insurance sectors, we show that credit risk transfer can be beneficial when banks face uniform demand for liquidity. However, when they face idiosyncratic liquidity risk and hedge this risk in an interbank market, credit risk transfer can be detrimental to welfare. It can lead to contagion between the two sectors and increase the risk of crises.     

Interest margins and bank regulation in Central America and the Caribbean

This paper examines empirically the determinants of bank interest margins in Central America and the Caribbean over the period 1998–2014. A particular focus is set on the impact of differences in the regulatory environment and market structure across countries in explaining the interest margins of individual banks. Our results suggest that bank market power, operating costs, credit risk, and liquid asset holdings increase the margin between loan and deposit rates, while increased income diversification and GDP growth are associated with lower loan-deposit spreads. When considering information on banking regulation, we find strong evidence to support our main hypothesis that improvements in market quality and liberalization have a significant effect on interest margins. More specifically, reductions in entry requirements to banking, higher involvement of foreign banks, and increased financial statement transparency are associated with significant reductions in interest margins.     

Banks’ earnings: Empirical evidence of the influence of economic and financial market factors

The structure of income is a foremost address within research on banks’ performance, especially with regard to effects on the resilience of banks’ earnings. Indeed, given their central position in the economy, banks shall thrive to generate sustainable earnings and control for their potential volatility. Existing studies mostly consider the weight of non‐net interest income (nonNII) as opposed to the traditional NII income source. Such aggregated nonNII is found to increase earnings risk but more granular studies conflict. We propose an original investigation of the influence of economic and financial conditions on various income types, assuming that performance may actually be driven by both the income structure and external conditions. We focus European banks, which have long been allowed to diversify beyond retail banking. Out of a straight panel framework, we question if the influence of external conditions spreads to earnings components other than credit losses and trading income and if it does allow for diversification benefits among components. We find that each component actually evolves owing to its own equation. Furthermore, effects of single variables may cumulate over different components of earnings (e.g. GDP) or provide with diversification benefits. These effects are all the more important since they are not mitigated by operating expenses. Hence, over a regarded period, banks’ performance depends upon their structure of income and upon volatilities and correlations of influential variables. Besides controlling for ex‐ante volatility, our approach shows that a given structure of income is not necessarily more resilient than others but that selected non‐banking income may support a higher stability of Earnings     

Systemic Bank Risk in Brazil: A Comprehensive Simulation of Correlated Market, Credit, Sovereign and Inter-Bank Risks

In this study we present a comprehensive forward‐looking portfolio simulation methodology for assessing the correlated impacts of market risk, private sector and Sovereign credit risk, and inter‐bank default risk. In order to produce better integrated risk assessment for banks and systemic risk assessments for financial systems, we argue that reasonably detailed modeling of bank asset and liability structures, loan portfolio credit quality, and loan concentrations by sector, region and type, as well as a number of financial and economic environment risk drivers, is required. Sovereign and inter‐bank default risks are increasingly important in the current economic environment and their inclusion is an important model extension. This extended model is demonstrated through an application to both individual Brazilian banks (i.e., 28 of the largest banks) and groups of banks (i.e., the Brazilian banking system) as of December 2004. When omitting Sovereign risk, our analysis indicates that none of the banks face significant default risk over a 1‐year horizon. This low default risk stems primarily from the large amount of government securities held by Brazilian banks, but also reflects the banks' adequate capitalizations and extraordinarily high interest rate spreads. We note that none of the banks which we modeled failed during the very stressful 2007‐2008 period, consistent with our results. Our results also show that a commonly used approach of aggregating all banks into one single bank, for purposes of undertaking a systemic banking system risk assessment, results in a misestimate of both the probability and the cost of systemic banking system failures. Once Sovereign risk is considered and losses in the market value of government securities reach 10% (or higher), we find that several banks could fail during the same time period. These results demonstrate the well known risk of concentrated lending to a borrower, or type of borrower, which has a non‐zero probability of default (e.g., the Government of Brazil). Our analysis also indicates that, in the event of a Sovereign default, the Government of Brazil would face constrained debt management alternatives. To the best of our knowledge no one else has put forward a systematic methodology for assessing bank asset, liability, loan portfolio structure and correlated market and credit (private sector, Sovereign, and inter‐bank) default risk for banks and banking systems. We conclude that such forward‐looking risk assessment methodologies for assessing multiple correlated risks, combined with the targeted collection of specific types of data on bank portfolios, have the potential to better quantify overall bank and banking system risk levels, which can assist bank management, bank regulators, Sovereigns, rating agencies, and investors to make better informed and proactive risk management and investment decisions.     

Bank pay caps,bank risk,and macroprudential regulation

This paper studies the consequences of a regulatory pay cap in proportion to assets on bank risk, bank value, and bank asset allocations. The cap is shown to lower banks’ risk and raise banks’ values by acting against a competitive externality in the labour market. The risk reduction is achieved without the possibility of reduced lending from a Tier 1 increase. The cap encourages diversification and reduces the need a bank has to focus on a limited number of asset classes. The cap can be used for Macroprudential Regulation to encourage banks to move resources away from wholesale banking to the retail banking sector. Such an intervention would be targeted: in 2009 a 20% reduction in remuneration would have been equivalent to more than 150 basis points of extra Tier 1 for UBS, for example.     

Multinational Banks and the Global Financial Crisis: Weathering the Perfect Storm?

We use data on the 48 largest multinational banking groups to compare the lending of their 199 foreign subsidiaries during the Great Recession with lending by a benchmark of 202 domestic banks. Contrary to earlier and more contained crises, parent banks were not a significant source of strength to their subsidiaries during 2008–09. When controlling for other bank characteristics, multinational bank subsidiaries had to slow down credit growth almost three times as fast as domestic banks. This was in particular the case for subsidiaries of banking groups that relied more on wholesale funding.

Competition and financial stability in European cooperative banks

Cooperative banks are a driving force for socially committed business at the local level, accounting for around one fifth of the European Union (EU) bank deposits and loans. Despite their importance, little is known about the relationship between bank stability and competition for these small credit institutions. Does competition affect the stability of cooperative banks? Does the financial stability of banks increase/decrease when competition is higher? We assess the dynamic relationship between competition and bank soundness (both in the short and long run) among European cooperative banks between 1998 and 2009. We obtain three main results. First, we provide evidence in line with the competition-stability view proposed by Boyd and De Nicolò (2005). Bank market power negatively “Granger-causes” banks' soundness, meaning that there is a positive relationship between competition and stability. Second, we find that this fundamental relationship does not change during the 2007–2009 financial crisis. Third, we show that increased homogeneity in the cooperative banking sector positively affects bank soundness. Our findings have important policy implications for designing and implementing regulations that enhance the overall stability of the financial system and in particular of the cooperative banking sector.     

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.     

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.     

Credit risk and financial integration: An application of network analysis

Credit plays a significant role in the performance of the banking sector. This research relates financial integration to the credit risk of banks. We compute a measure of financial connectivity based on network statistics using syndicated loans. Using instrumental variable techniques for a panel of 39 countries over the periods of 1988 to 2014, we analyse the link between credit risk and financial integration. Our findings suggest that borrowing banks do not alleviate credit risk. Also, borrowing banks that are more active in the network also help to compound credit risk. However, the closeness centrality reveals a significant reduction in the credit risk of the borrowing banks. Our findings from individual countries reflect the significance of the country of operation of these banks in the international market.     

The effects of revenue diversification and cross border banking on risk and return of banks in Africa

The paper analyses the implications of revenue diversification and cross-border banking for risk and return. We sample 320 banks across 29 African countries and employ System GMM estimator as a methodological approach to shed further light on the diversification-stability nexus by examining the complex interaction between three key variables: cross-border banking, diversification and bank stability. The results suggest that exploration risk reduces diversification as the level of capital increases when banks cross border to diversify across revenue generating activities. Our analyses further show that, banks in Africa derive absolute benefits from diversification if they cross border and diversify their revenue base concurrently. These results are robust to a range of controls including alternative variable specifications, regulatory environment that bank operate and methodology.
