Early warning systems and systemic banking crises in low income countries: A multinomial logit approach

This paper estimates an early warning system (EWS) for predicting systemic banking crises in a sample of low income countries in Sub-Saharan Africa. Since the average duration of crises in this sample of countries is longer than one year, the predictive performance of standard binomial logit models is likely to be hampered by the so-called crisis duration bias. The bias arises from the decision to either treat crisis years after the onset of a crisis as non-crisis years or remove them altogether from the model. To overcome this potential drawback, we propose a multinomial logit approach, which is shown to improve the predictive power of our EWS compared to the binomial logit model. Our results suggest that crisis events in low income countries are associated with low economic growth, drying up of banking system liquidity and widening of foreign exchange net open positions.     

宏观审慎政策协调能否抑制国际性银行危机传染？——基于跨境金融关联视角的实证研究

本文基于跨境金融关联视角对宏观审慎政策能否抑制国际性银行危机传染这一重要的理论与实践问题进行了实证研究。选取亚洲金融危机和全球金融危机时期遭受冲击的10个代表性国家作为样本,构建Logit模型和多元回归模型探讨本国及具有金融关联的国家协调实施宏观审慎政策对本国系统性银行危机传染的影响。研究表明,具有金融关联的国家出现金融危机会显著增加本国系统性银行危机的发生概率,具有金融关联的国家实施宏观审慎政策对本国信贷的影响比对房价的影响更明显,本国及具有金融关联的国家协调实施宏观审慎政策会显著降低本国系统性银行危机的发生概率。在调整银行危机指标及考虑贸易关联和流动性风险的影响后,研究结果依然保持稳健。本文的研究结论揭示了加强宏观审慎政策协调有助于维护全球金融稳定,对于中国政策当局强化宏观审慎管理具有极其重要的政策含义。     

Bank regulation,property prices and early warning systems for banking crises in OECD countries

Early warning systems (EWS) for banking crises generally omit bank capital, bank liquidity and property prices. Most work on EWS has been for global samples dominated by emerging market crises where time series data on bank capital adequacy and property prices are typically absent. We estimate logit crisis models for OECD countries, finding strong effects from capital adequacy and liquidity ratios as well as property prices, and can exclude traditional variables. Higher capital adequacy and liquidity ratios have a marked effect on the crisis probabilities, implying long-run benefits to offset some of the costs that such regulations may impose.     

Financial markets development,business cycles,and bank risk in South America

In this paper, we examine whether banking crises or business cycles affect the influence of financial markets development on bank risk in a sample of 37 publicly listed commercial banks in seven South American countries over a 22-year period between 1991 and 2012. Banking crises in this region offer a natural setting in which the impact of financial markets development on bank risk is examined. We find that financial markets development improves banks’ capitalization ratio and reduces their exposure to non-traditional banking activities, suggesting that financial markets development on average reduces bank risk. In addition, banking crises and business cycles appear to moderate the impact of financial markets development on bank risk. In the aftermath of banking crises, banks appear to concentrate more on their core traditional banking activities.     

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.     

Dynamical macroprudential stress testing using network theory

The increasing frequency and scope of financial crises have made global financial stability one of the major concerns of economic policy and decision makers. This has led to the understanding that financial and banking supervision has to be thought of as a systemic task, focusing on the interdependent relations among the institutions. Using network theory, we develop a dynamic model that uses a bipartite network of banks and their assets to analyze the system’s sensitivity to external shocks in individual asset classes and to evaluate the presence of features underlying the system that could lead to contagion. As a case study, we apply the model to stress test the Venezuelan banking system from 1998 to 2013. The introduced model was able to capture monthly changes in the structure of the system and the sensitivity of bank portfolios to different external shock scenarios and to identify systemic vulnerabilities and their time evolution. The model provides new tools for policy makers and supervision agencies to use for macroprudential dynamical stress testing.     

银行业危机:金融泡沫视角的分析

自20世纪80年代以来,银行业危机爆发越显频繁。然而,通过对银行业危机内部形成机理分析可以发现,银行业危机的爆发其实是伴随着金融泡沫的形成与破灭这一过程的。在金融泡沫的形成过程中,银行往往会给一些高风险行业发放贷款,从而增加银行经营风险;而在金融泡沫破灭之后,这将直接或间接地导致银行产生大量的不良贷款,从而使银行业危机最终爆发。因此,我国应尽快化解国有商业银行的不良资产;完善银行微观治理结构;建立和完善金融监管机制。     

国际资本流动“突然停止”、银行危机及其产出效应

国际资本流动突然停止是新兴市场国家金融全球化和金融开放早期面临的重要障碍。本文运用20个新兴市场国家1976~2006年间的面板数据,考察突然停止和银行危机对宏观经济产出的影响。研究发现:突然停止或银行危机都不必然导致产出的大幅下降;如果银行部门不发生系统性的危机,突然停止对产出没有显著影响;给定国际资本流动不出现大幅的逆转,银行危机对产出的影响也不显著;突然停止和银行危机的叠加则对产出造成严重的负面冲击,经济增长率显著下滑。研究结论有重要的政策含义,表明构建一个稳固的银行体系对于一国金融开放和金融自由化过程中的经济安全至关重要。     

How resilient is the German banking system to macroeconomic shocks?

Macroeconomic stress testing studies often rely on rather short sample periods due to the limited availability of banking data. They may fail to appropriately account for the cyclicality in the interaction between the banking system and macroeconomic developments. In this paper, we use a newly constructed data set on German banks’ income and loss statements over the past 39 years to model the interaction between the banking sector and the macroeconomy. Our VAR analysis indicates that the level of stress in the banking sector is strongly affected by monetary policy shocks. The results rationalize the active behavior of central banks observed during periods of financial market crises.     

The Twin Crises: Determinants of Banking and Currency Crises in the Turkish Economy

Several twin crises occurred in the Turkish economy in the last three decades. In this article, we aim to analyze the link between banking and currency crises and to illustrate the essential determinants of these twin crises by developing a multivariate logit model for the period 1990–2013. The empirical findings show that Turkish currency crises are mainly due to excessive fiscal deficits, rises in short-term external debt, overvaluation of Turkish lira, and external adverse shocks; banking crises are primarily caused by excessive money supplies and bank short positions. The empirical findings also indicate that banking crises lead to currency crises, and vice versa.     

Measuring aggregate risk: Can we robustly identify asset-price boom–bust cycles?

We investigate the extent to which it is possible to detect asset-price booms and banking crises according to alternative identification strategies and we assess their robustness. We find some evidence that house price-booms are more likely to turn into costly recession or to trigger a banking crisis than stock-price booms. Resorting both to a non-parametric approach and a discrete-choice (logit) model, we analyze the ability of a wide set of indicators to robustly explain costly asset-price booms. According to our results, real long-term interest rates and real stock prices tend to increase the probability of a costly housing-price boom, whereas real GDP tends to increase the probability of a costly stock-price boom. Interestingly, the credit-to-GDP gap indicator, sometimes put forward in the literature as a key reference for setting countercyclical capital buffers, does not seem to be a robust leading indicator of costly booms or banking crises.     

政策连续性、非金融企业影子银行化与社会责任承担

基于2006-2017年非金融类A股上市公司数据,本文考察了非金融企业影子银行化对社会责任承担的影响,并进一步研究了政策连续性对非金融企业影子银行化与社会责任承担之间关系的影响。研究发现,非金融企业影子银行化会抑制社会责任承担行为,且这种效应在市场套利动机强、公司治理水平较低、外部融资能力弱的企业中更为明显。政策连续性程度提高会减弱非金融企业影子银行化与社会责任承担之间的负向关系。因此,本文提出抑制经济“脱实向虚”,增强政策稳定性和连续性,促进实体经济平稳发展的政策建议。     

Lessons from the Tequila Crisis

This paper draws several important lessons from the Tequila Crisis of 1994 and 1995. The overriding lesson is that the dynamics of financial crises in emerging market countries differ from those in industrialized countries because institutional features of their debt markets differ. Several policy lessons for emerging market countries also emerge from the analysis: (1) pegged exchange-rate regimes are extremely dangerous, (2) strong prudential supervision of the banking system is critical for prevention of financial crises, (3) financial liberalization must be managed extremely carefully and (4) different policies are needed to promote recovery in emerging market countries than those that are applicable to industrialized countries.     

Financial crises and emerging stock markets volatility: do internal factors matter?

This paper has two central aims. The first one is to deal empirically with the effects of financial crises on emerging stock markets volatility. The second objective consists in testing if the level of stock market development affects this relationship. For this purpose, we estimate a static panel data model for a sample of nine emerging economies from January 1990 to December 2006. We consider three types of financial crises, i.e. banking, currency and twin crises. Our empirical results suggest that the onset of financial crises strongly increased stock market volatility. In addition, we find that the biggest impact is exerted by twin crises. When dealing with the second objective, our results show that the market size and the liquidity level can attenuate the effects of banking and currency crises, but not the one associated to twin crises. Nevertheless, the degree of stock market integration seems to reduce the effects of banking, currency and twin crises on stock market volatility.     

Financial crisis,structure and reform

In this study, we examine the relationship between the structure of financial systems and financial crises. Using cross-country data on financial structures and crises, we find that there is a significant short-term reversal in development of the banking sector and the stock market during both bank crises and market crashes, with the corporate bond market moving in the same direction as bank credit. However, the results are significant for countries with market-based financial systems but not for countries with bank-based financial systems. Emerging markets have mainly bank-based financial systems, which may explain why these markets require more time to recover from economic downturns after a financial crisis. Therefore, we argue that governments should emphasize a balanced financial system structure as it helps countries to recover from financial crises more quickly compared with countries that lack such balanced structures.     

Financial crisis,Omori's law,and negative entropy flow

The 2008 global financial crisis has revived great interest in early warning system (EWS) models for reducing the risks of future crises. Existing EWS models employ aggregated variables that cannot examine the nonlinear dynamics of participating players on scales smaller than a country in unstable, non-equilibrium economies. To help understand the mechanism of financial crises and identify new robust indicators for financial crises and economic recessions, in this work, we take an “anatomical” approach, i.e., to examine the income structures of different sectors of an economy separately, as well as to analyze the exposure networks associated with Fannie Mae/Freddie Mac, Lehman Brothers, and American International Group. We show that the losses in exposure networks can be modeled by a two-parameter Omori-law-like distribution for earthquake aftershocks. Such a distribution suggests that losses will be widespread around crises or recessions. Indeed, around crises or recessions, the heavy-tailed distributions for the negative income cluster are even heavier than those for the positive income cluster. Consequently, the entropies associated with the distribution of the negative income cluster exceed that of the positive income cluster. Moreover, instability propagates from the crisis initiating sector to other sectors. Therefore, the anatomical approach developed here can indeed shed some light on the detailed dynamics of financial crises and economic recessions, and the distribution and entropy approaches can help predict economic downturns.     

The use of blanket guarantees in banking crises

Policymakers often use guarantees on bank liabilities to prevent or contain bank runs during systemic banking crises, but their success has been debated. Using a sample of 42 episodes of banking crises, this paper finds that blanket guarantees do help to reduce liquidity pressures on banks, but only partially since they do not stem withdrawals from non-residents. Withdrawals following the announcement of guarantees are much more pronounced for non-resident liabilities than for foreign-currency denominated deposits—which may also be held by residents—suggesting that the results on non-residents are not driven by foreign-currency risk but by concerns about the government’s ability and commitment to honor the guarantee to non-resident liability holders.     

Costs of financial instability, household-sector balance sheets and consumption

Extant work on costs of financial instability focuses on fiscal costs and declines in aggregate GDP following banking crises. We estimate effects of banking and currency crises on consumption in 19 OECD countries, showing consumption plays an important role in the adjustment following a crisis, and effects are not captured solely by the impact of crises on standard consumption determinants, income and wealth. Additional effects, attributable to factors such as time-varying confidence, uncertainty and credit rationing, are aggravated by high and rising leverage, despite financial liberalisation easing liquidity constraints. High leverage implies that banking crises taking place now could have greater incidence than in the past.     

The real effect of banking crises: Finance or asset allocation effects? Some international evidence

This paper analyzes whether the decline in economic growth that follows a banking crisis occurs because of a reduction in the amount of credit available (finance effect) or a worsening in the allocation of investable resources (asset allocation effect). We use a sample of more than 2500 industrial firms in 18 developed and developing countries that experienced 19 systemic banking crises between 1989 and 2007. The results indicate that banking crises negatively affect firms’ intangible investments, which intensifies the economic downturn. The negative growth effect produced by the worsening of the investment allocation is stronger in countries with highly developed financial systems and institutions.     

Does financial connectedness predict crises?

The global financial crisis has reignited interest in models of crisis prediction. It has also raised the question whether financial interconnectedness—a possible source of systemic risk—can serve as an early warning indicator of crises. In this paper, we examine the ability of connectedness in the global network of financial linkages to predict systemic banking crises during the 1978–2010 period. Our results indicate that increases in a country’s own connectedness and decreases in its neighbours’ connectedness are associated with a higher probability of banking crises after controlling for macroeconomic fundamentals. Our findings suggest that financial interconnectedness has early warning potential, especially for the 2007–2010 wave of systemic banking crises.
