Did the Market Signal Impending Problems at Northern Rock? An Analysis of Four Financial Instruments

The academic literature has regularly argued that market discipline can support regulatory authority mechanisms in ensuring banking sector stability. This includes, amongst other things, using forward‐looking market prices to identify those credit institutions that are most at risk of failure. The paper's key aim is to analyse whether market investors signalled potential problems at Northern Rock in advance of the bank announcing that it had negotiated emergency lending facilities at the Bank of England in September 2007. A further aim of the paper is to examine the signalling qualities of four financial market instruments (credit default swap spreads, subordinated debt spreads, implied volatility from options prices and equity measures of bank risk) so as to explore both the relative and individual qualities of each. The paper's findings, therefore, contribute to the market discipline literature on using market data to identify bank risk‐taking and enhancing supervisory monitoring. Our analysis suggests that private market participants did signal impending financial problems at Northern Rock. These findings lend some empirical support to proposals for the supervisory authorities to use market information more extensively to improve the identification of troubled banks. The paper identifies equities as providing the timeliest and clearest signals of bank condition, whilst structural factors appear to hamper the signalling qualities of subordinated debt spreads and credit default swap spreads. The paper also introduces idiosyncratic implied volatility as a potentially useful early warning metric for supervisory authorities to observe.     

A Cross‐Country Analysis of the Bank Supervisory Framework and Bank Performance

Ongoing changes in the structure and nature of banking, as well as banking crises across the globe have focused the attention of policy makers on the appropriate structure, scope, and degree of independence of banking supervision. Key issues for banking supervision structure are whether there should be one or multiple supervisory authorities, and whether the central bank should be involved in bank supervision. The issue pertaining to the scope of supervision is whether bank supervisory authorities should supervise other financial service industries, including in particular securities and insurance. Finally, the issue regarding the independence of supervisory authorities is the degree to which bank supervisors should be subject to political and economic policy pressure and influence. How these issues are addressed is important, because policies that fail to provide for an appropriate bank supervisory framework may undermine bank performance and even lead to full‐scale banking crises. The intense interest policy makers have shown in these issues has not been matched, however, by researchers. In particular, there is very little systematic empirical evidence on how, or indeed whether, the structure, scope, or independence of bank supervision affects the banking industry. This paper addresses this gap in three respects. First, drawing on the existing literature, we discuss the various policy issues surrounding the structure, scope, and degree of independence of bank supervision. Second, we provide comparative information on the actual choices that have been made regarding these three aspects of supervision across a wide range of developed and emerging market economies. Third, using both country‐specific data for 55 countries in all parts of the world, and data for over 2,300 individual banks in those countries, we examine the relationship between the structure, scope, and independence of bank supervision and one key dimension of the banking industry – bank profitability. Our results indicate, at most, a weak influence for the structure of supervision on bank performance. In particular, we find some evidence that a single‐supervisor system enhances bank performance. However, following our discussion of the caution one must use in interpreting data on the supervisory framework, our re‐estimates using an alternative source of data on the structure of supervision failed to duplicate this result. Our results have a bearing on a key dimension of the policy debate on how to structure supervision. In particular, given the dearth of empirical evidence on the issues, advocates of one form or another of supervisory structure have asserted that a particular change is likely to affect (favorably or adversely, as the advocate sees fit) the performance of banks. Our results provide little support at best to the belief that any particular bank supervisory structure will greatly affect bank performance. This is significant, because it suggests that the on‐going debate might more broadly focus on the impact of the supervisory structure on other aspects of the health of the banking system, including individual bank safety and soundness, systemic stability, and the development of the banking system.     

资产价格波动与银行系统稳定

有关金融危机的理论研究表明,资产价格波动与银行脆弱性之间存在很强的相关性。资产价格波动主要通过信贷风险渠道、市场风险渠道、经纪业务收入渠道、为附属机构注资的风险渠道及“第二回合”渠道等传导渠道影响到银行系统的稳定。发生在斯堪的纳维亚和日本的银行危机证明,资产价格剧烈波动确实会造成严重的银行问题,所以为维持银行系统的稳定,监管当局应该密切关注资产价格可能出现的剧烈下跌对银行部门可能产生的风险并采取应对方法。     

金融深化是化解民间借贷危机的根本途径

以温州为代表的民间借贷危机的发生,折射出我国金融体制方面的制度性问题。金融压抑是民间借贷危机的根本原因,银行大企业集团等参与民间放贷对危机发生推波助澜,紧缩的货币政策是民间借贷危机爆发的导火索。金融深化是化解民间借贷危机的根本途径。民间借贷危机爆发,也倒逼金融体制要加快改革步伐,现在到了该放开金融领域进入和利率管制,打破现有银行垄断体制,建立由市场资金供求决定各种利率水平的市场利率体系的时候了。     

Europäische Streitbeilegungsmechanismen bei Meinungsverschiedenheiten zwischen nationalen Versicherungsaufsichtsbehörden

In the course of the reconstruction of the European financial supervisory framework all level 3-committees (namely CEIOPS for the insurance sector) were re-established as fully-fledged authorities of the European Union. These authorities are granted authority to take decisions with immediate effect towards national supervisors. The European Financial Supervisory Authorities, however, form but the upper level of the European micro-prudential supervisory system. The day-to-day supervision of the financial markets will remain to be vested in the national supervisory authorities. By retaining a system, in which the financial supervision takes place primarily at the national level, one also remains to be faced with problems, where insurance undertakings or insurance groups act under the jurisdiction of several national supervisors. Disagreements between these supervisors will, thus, remain to be commonplace. In order to dissolve such disputes, the European legislator has provided for a formalised dispute resolution procedure in granting EIOPA a power to settle disagreements.     

Assessing competitive conditions in the Greek banking system

This paper uses the Rosse-Panzar statistic to assess empirically competitive conditions in the Greek banking system over the period 1993–1995. The competitiveness of the banking system is evaluated using a non-structural estimation technique. The results indicate that bank revenues were earned as if under conditions of monopolistic competition. The gradual elimination of exchange controls, the capital movement liberalisation, the enactment of the Second Banking Directive of the European Union and the supervisory arrangements have been related to the competitive conditions of the Greek banking system.     

中国对外资银行的监管制度分析——以相关外资银行管理条例为视角

外资银行是中国银行业的重要组成部分,中国于1994年、2001年和2006年先后颁布的三个外资金融机构管理条例及其相应的实施细则,集中体现了中国对WTO承诺的履行和外资银行监管制度的发展,也标志着中国银行业(中国加入WTO过渡期最长的一个行业)从此进入完全开放的时代.2006年12月,中国在入世过渡期结束时采用的新《中华人民共和国外资银行管理条例》在市场开放、履行WTO承诺等各方面有了很大进展.不过中国仍然需要在对外资银行的审慎监管、法人银行导向、国民待遇落实和统一监管等问题上做出进一步的努力.     

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.     

Freeing Greece from capital controls: Were the restrictions enforced in time?

Recent developments in Greece have caused for the implementation of banking capital controls on the outflow of funds, a policy decision not uncommon, especially in emerging markets. However, the issues of the Greek economy, which seem to stem from the public sector but have been passed on to the banking sector, pose a unique challenge to researchers. In this paper, we employ VBanking, an object-oriented model for banking simulations to examine whether capital controls in Greece were enforced at the appropriate time. Additionally, we propose that the banking sector will not purge this regulation soon. Finally, we demonstrate the destructive effects of capital controls both on the financial system and on the real economy. We present the empirical results of our work, which suggest that the Greek authorities’ response to the deterioration of the banking sector was lagged.     

Corruption,soundness of the banking sector,and economic growth: A cross-country study

This paper explores the impact of corruption on both the banking sector and economic growth; we determine the impact using 76 macroeconomic data from various countries over the period 2002–2004. The results of various cross-sectional regressions provide substantial evidence that corruption significantly aggravates the problems with bad loans in the banking sector. In this study, we also find some evidence of a new channel through which corruption lowers economic growth: Corruption distorts the allocation of bank funds from normal projects to bad projects, which decreases the quality of private investments, hence it decreases economic growth.     

Banking Mergers: The Impact of Financial Liberalization on the Taiwanese Banking Industry

The objective of this paper is to examine the nature of the Taiwanese banking sector and to analyze the impact of financial liberalization on the Taiwanese banking industry. We present empirical evidence to show that the recent wave of bank mergers observed in other countries is also suitable for Taiwan. Based on empirical results for overall economies of scale and expansion path subadditivity, Taiwanese banks should obtain the benefit of scale economies by merging with other banks rather than expanding by opening more branches. Furthermore, we show that the Relative Market Power hypothesis—which postulates that greater market shares lead to higher profitability—finds empirical support in Taiwanese banking data after financial reforms were enacted.     

Credit booms,banking crises,and the current account

A number of papers have shown that rapid growth in private sector credit is a strong predictor of a banking crisis. This paper will ask if credit growth is itself the cause of a crisis, or is it the combination of credit growth and external deficits? This paper estimates a probabilistic model to find the marginal effect of private sector credit growth on the probability of a banking crisis. The model contains an interaction term between credit growth and the level of the current account, so the marginal effect of private sector credit growth may itself be a function of the level of the current account. We find that the marginal effect of rising private sector debt levels depends on an economy's external position. When the current account is in balance, the marginal effect of an increase in debt is rather small. However, when the economy is running a sizable current account deficit, implying that any increase in the debt ratio is financed through foreign borrowing, this marginal effect is large.     

Regulation,supervision and deposit insurance for financial cooperatives: an empirical investigation

This paper analyses the impact of different regulation and supervision approaches, as well as deposit insurance schemes, on the development of financial cooperatives in developing countries, using random and fixed effects estimators. Information on laws regulating financial cooperatives, the supervisory approaches adopted, and deposit insurance schemes in sixty-five developing countries were collected—mostly—from original legislations for the period 1995–2014. Key findings suggest that indicators of financial cooperative development are positively correlated with the existence of a specialized regulation; supervision under non-bank financial supervisory authorities; and the presence of deposit insurance schemes, while general cooperative society’s regulations and banking regulations are negatively correlated with financial cooperatives’ indicators. These results are robust after controlling for economic and institutional factors as well as potential endogeneity bias.     

East German capital stock deficits remain high

Conclusion Since the government cannot anticipate any more precisely than private investors which sectors will turn out to be particular growth areas in the future, it should not follow a course of sector-oriented structural policies — not even in east Germany. The achievement of virtually similar investment conditions as in west Germany has, given the investment in infrastructure over the past five years, come a long way. Since infrastructural consolidation takes time, however, and since, as west German regional policy experience has shown, an adequate infrastructure alone is no guarantee for average or above-average growth of a particular region, broadly based investment support measures were, for a time, sensible. In order to gradually allow for the market selection process to take over and to reduce the burden on public spending, however, consideration should now be given to tightening investment support measures. With all the problems that selecting particular sectors to support brings with it, one must acknowledge that, given the specifics of the east German transformation process, the manufacturing sector was — and continues to be — exposed to the greatest pressures. For this reason, support should be concentrated in this area, especially since various spillover effects from manufacturing can be expected to manifest themselves in other areas, such as services.

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.     

Banking deregulation and innovation

We document empirical support for a key micro-level channel—innovation by young, private firms—through which financial sector deregulation affects economic growth. We find that intrastate banking deregulation, which increased the local market power of banks, decreased the level and risk of innovation by young, private firms. In contrast, interstate banking deregulation, which decreased the local market power of banks, increased the level and risk of innovation by young, private firms. These contrasting effects on innovation also translated into contrasting effects on economic growth. Our study suggests that the nature of financial sector deregulation crucially affects its potential benefits to the real economy.

Does interest rate and its volatility affect banking sector development? Empirical evidence from emerging market economies

This study investigates the relationship between interest rate, interest rate volatility, and banking sector development in 12 emerging market economies located around the world. For this purpose, panel data analysis was conducted using annual data from 1980 to 2014. In parallel to the financial development literature, which asserts that banking sector development, as a broad and complex concept, cannot be measured by a single indicator, this study adopts a set of measures of banking sector development. The empirical results reveal that while interest rate has a positive impact on all banking sector indicators, this relationship weakens at higher interest levels, showing a concave relationship between interest rate and banking sector development. In addition, the empirical results provide evidence that interest rate fluctuations have a negative impact on most banking sector development (BSD) indicators, suggesting that the banking sectors of emerging countries are vulnerable to interest rate risks. Furthermore, all measures of the banking sector indicators are positively affected by economic growth rates, while this association weakens at higher levels of income, confirming a nonlinear relationship. Thus, the results have important implications for policymakers in improving the banking system and promoting the economic growth of these emerging economies.     

Heterogeneous market structure and systemic risk: Evidence from dual banking systems

This paper investigates how banking system stability is affected when we combine Islamic and conventional finance under the same roof. We compare systemic resilience of three types of banks in six GCC member countries with dual banking systems: fully-fledged Islamic banks (IB), purely conventional banks (CB) and conventional banks with Islamic windows (CBw). We employ market-based systemic risk measures such as MES, SRISK and CoVaR to identify which sector is more vulnerable to a systemic event. We also compute weighted average GES to determine which sector is most synchronised with the market. Moreover, we use graphical network models to determine the most interconnected banking sector that can more easily spread a systemic shock to the whole system. Using a sample of observations on 79 publicly traded banks operating over the 2005–2014 period, we find that CBw is the least resilient sector to a systemic event, it has the highest synchronicity with the market, and it is the most interconnected banking sector during crisis times.     

中国银行业结构性全要素生产率增长研究

在深化银行业供给侧结构性改革背景下,如何科学评价银行业的结构性全要素生产率(TFP)增长具有重要意义。区别于早期针对个体样本的技术性TFP增长研究,本文通过构建并分解加总的Luenberger生产率指标对我国银行业以及不同类型银行的结构性TFP增长及来源进行有效评价。结果显示,研究期间,我国银行业的结构性TFP增长表现良好,其中,整体技术进步是主要驱动力;进一步分解发现,制度创新改善和加总的个体技术进步推动了银行业结构性TFP增长。在整体效率变化方面,加总的个体技术效率变化和结构效率变化都有待提高,其中,范围效率变化是抑制结构效率改善的主要因素。考虑不同类型银行,制度创新变化对所有类型银行的结构性TFP增长都影响显著,加总的个体技术变化对股份制和地区性银行的结构性TFP增长贡献更突出;加总的个体技术效率变化、结构效率变化、范围效率变化和规模效率变化对不同类型银行的结构性TFP增长作用有限。
