European banking integration, ten years after

Ten years ago, the White Paper on the Completion of the Single Market announced the integration of European banking markets. the purpose of this essay is to identify four public issues that remain to be addressed. Home country control of international banks need to be complemented by host country control. the deposit guarantee schemes should be modified by rendering insured deposits ‘first order claim’. A European authority is needed to ensure that banks do not exploit domestic rents to subsidise international activities. Finally, tax evasion is a fourth issue that remains to be addressed.     

Strategic Management of Cost Efficiencies in Networks: Cross-country Evidence on European Branch Banking

This paper examines the role of cost efficiencies on efficient management of branch networks in the contemporary European commercial banking industry. The analysis, which could be generalised to other industries, indicates that larger banks are more likely to have heavily utilised branch networks than smaller banks and to exhibit fewer cost efficiencies from building more branches. The finding of this result within each country suggests the role of internal firm size regardless of competitive conditions. The similar cross‐country finding suggests the impact of factors such as market structure/concentration levels and type of non‐price competition. Larger banks can generate less income per unit asset deployed. Cross‐border efficiency might be improved by greater use of banks with under‐used networks by banks with over‐used networks.     

A New Development Database. Deposit Insurance around the World

In the past two decades, in a series of banking crises aroundthe world, banks have become systematically insolvent. Thesecrises have occurred in developed and developing economies alike.To make such financial system breakdowns less likely and tolimit their costs if they occur, policymakers feel the needfor financial safety nets. These include such policies as implicitor explicit deposit insurance, a lender of last resort functionof the central bank, bank insolvency resolution procedures,and bank regulation and supervision. Of these policies, explicitdeposit insurance has been gaining popularity in recent years.Since the 1980s the number of countries with explicit depositinsurance schemes almost tripled, with most OECD countries andan increasing number of developing economies adopting some formof explicit depositor protection. In 1994 deposit insurancebecame the standard for the newly created single banking marketof the European Union. Establishing an explicit deposit insurancescheme became part of the generally accepted best practice advicegiven to developing economies.     

Are foreign banks more profitable than domestic banks? Home- and host-country effects of banking market structure, governance, and supervision

Using both bank- and country-level data on banking sectors from 70 countries over the period 1992-2006, this paper empirically investigates the joint home- and host-country effects of banking market structure, macroeconomic condition, governance, and changes in bank supervision on foreign bank margins. We find that foreign banks are more profitable than domestic banks when they operate in a host country whose banking sector is less competitive and when the parent bank in the home country is highly profitable. Moreover, when foreign banks operate in a host country with lower growth rates of GDP, higher interest and inflation rates, and more stringent regulatory compliance with Basel risk weights, their margins increase. Specifically, changes in bank supervision of a parent bank’s ownership restrictiveness in the home country significantly increases foreign bank margins, while supervisory changes in regulatory compliance with Basel risk weights in the host country enhances foreign bank margins.     

Cross‐Border Bank M&As and Risk: Evidence from the Bond Market

The impact of cross‐border bank M&As on bank risk remains an open question. Though geographically diversifying bank M&As have the potential to reduce the risk of bank insolvency, they also have the potential to increase that risk due to the increase in risk‐taking incentives by bank managers and stockholders following these transactions. This paper empirically investigates whether cross‐border bank M&As increase or decrease the risk of acquiring banks as captured by changes in acquirers' yield spreads. This paper also investigates how differences in the institutional environments between bidder and target countries affect changes in yield spreads following M&A announcements. The study finds that bondholders, in general, perceive cross‐border bank M&As as risk‐increasing activities, unlike domestic bank mergers. Specifically, on average, yield spreads increase by 4.13 basis points following the announcement of cross‐border M&As. This study also finds that these yield spreads are significantly affected by the differences in investor‐protection and deposit insurance environments between the transacting countries. However, the study does not find that the regulatory and supervisory environment in the home countries of the transacting parties significantly affects the changes in yield spreads. The overall evidence suggests that regulators should judge the relative environment in both the home and the host countries in evaluating the associated risks of an active multinational financial institution and in setting the sufficiency of the banks' reserve positions.

跨国银行并表监管与金融隐私权的冲突及制衡

在金融全球化、金融一体化、金融自由化和金融集团化的趋势下,包括发达国家和发展中国家在内的很多实力雄厚的大银行纷纷走出国门,进行全球扩张和跨国并购,成为国际金融市场上的跨国银行.这种跨国银行的产生和经营给普通的银行监管带来挑战,为了避免对跨国银行监管漏洞的存在从而危及整个国际金融体系的稳健,巴塞尔委员会提出了跨国银行并表监管的核心监管原则.但是在母国具体实施跨国银行并表监管过程中,会遇到东道国保护金融隐私权的法律障碍.因此,由于金融信息披露和金融信息交流所引发的并表监管和金融隐私权保护之间的冲突是不可避免的,为了整个国际金融体系的稳定就必须对两者的冲突进行价值和机制制衡.     

The entry and the activity level of foreign banks in Italy: An analysis of the determinants

Although the theory of multinational banking has pointed out the importance of local profit opportunities, the empirical evidence is still poor and deserves further investigation. To this end, we analyse entry decisions and activity levels of foreign banks operating in Italy between 1983 and 1998. We consider 22 OECD countries, 10 of which had at least one bank (branch or subsidiary) in Italy. Entries and activity levels were related to the degree of economic integration as well as to the financial market features of the home country relative to Italy.Unlike other studies, besides economic integration, the relative profitability of the banking activity proves to be a significant variable in that it highlights the importance of local market conditions. In the past decade, increased competition in the Italian banking sector has reduced these profit opportunities, driving foreign banks towards more innovative sectors of financial intermediation.     

差别化存款保险费率与银行风险承担——基于我国农村银行的经验证据

本文拓展了Freixas and Rochet(2008)的理论模型,证明存款保险差别化费率机制对银行风险承担具有抑制作用,在此基础上选取我国农村银行为研究对象,运用2015—2019年某省119家法人投保机构进行实证检验。研究发现:引入差别化费率设计显著降低了农村银行的风险承担;这一作用存在异质性,对于自身风险承担水平较低、资产规模较大的农村银行来说,抑制作用更为明显。进一步研究发现,差别化费率机制在一定程度上缓和了农信社改制短期内对农商行风险可能造成的不利影响。本文结论对加强存款保险制度的早期纠正功能、防范化解金融风险以及深化农村金融机构改革具有一定的理论意义和参考价值。     

Bank globalization and efficiency: Host- and home-country effects

Analyzing 126 countries for 1995–2013, we investigate the link between bank globalization and efficiency from the perspective of both host and home countries. We find strong and consistent evidence that foreign bank entry is associated with lower efficiency in host countries (host-country effect), while foreign expansion in the banking sector improves the efficiency of banks at home (home-country effect). We further observe that the effect of bank globalization is dependent on the regulatory and institutional regimes of the respective host (home) countries. Specifically, stringent activity restrictions, tight supervision, fewer limitations on foreign banks, lower market entry barriers, and less government interference all help mitigate the efficiency loss from foreign bank entry. Less supervision power, multiple supervisors, more restrictions on foreign banks, and a competitive banking market are all conducive to the higher efficiency gain of incumbent domestic banks from the respective country’s outward investments in the banking sector. Moreover, we find that the adverse impact on efficiency from foreign bank presence is less pronounced for less risky, more profitable, and larger banks, while banks that are more efficient, more profitable, taking on more risk, and/or smaller gain more efficiency from their country’s foreign expansion.     

Banking crises and market discipline: International evidence

This paper analyzes the effect of banking crises on market discipline in an international sample of banks. We also evaluate how bank regulation, supervision, institutions, and crisis intervention policies shape the effect of banking crises on market discipline. We control for unobservable bank, country, and time specific effects using a panel data set of banks from 66 countries around 79 banking crises. The results suggest that on average market discipline weakens after a banking crisis. This weakening is higher in countries where bank regulation, supervision, and institutions promoted market discipline before the banking crisis, and where a more accommodative approach is adopted to resolve it.     

银行监管和股东属性对银行风险的影响——基于新兴经济体的监管数据分析

银行监管按世界银行的标准划分为总体监管和12类分项监管;银行大股东属性包括政府类、金融企业类、外资类等.总体监管可以有效地降低银行风险;大股东为工业类、金融类企业的银行能够更好地控制风险,而家族类银行的风险程度较高;通过对分项监管进行研究可以发现,加强对所有权、资本要求、经营活动限制、外部审计要求、流动性、存款保险制度、退出及监管效率八个方面的监管可降低银行总体风险,而加强准入、内部管理、资产分类配置、信息披露这四类监管反而会增加银行总体风险.     

Banking regulation and the output cost of banking crises

Using a cross-section time-series of 47 banking crisis episodes in 35 industrial and emerging market economies between the 1970s and 2003, this study analyses the relationship between banking regulation and supervision, and the severity of banking crises measured in terms of the magnitude of output loss. The empirical results show that countries that provide comprehensive deposit insurance coverage and enforce strict bank capital adequacy requirements experience a smaller output cost of crises. Restrictions on bank activities also influence the severity of crises. The results, however, do not suggest that there is a significant impact of bank supervision. In addition, there is no robust evidence that the magnitude of the output cost of crises depends on the extent of banks’ financial intermediation.     

Multiple safety net regulators and agency problems in the EU: Is Prompt Corrective Action partly the solution?

Prompt Corrective Action (PCA) provides a more efficient mechanism for dealing with problem banks operating in more than one European country. In a PCA framework, a bank's losses are likely to be substantially reduced. This reduction in the losses to deposit insurance and governments will improve the problem of allocating those losses across the various insurance schemes and make it less likely that any deposit insurer will renege on its obligations in a cross-border banking crisis. This paper presents a stylized mechanism aimed at dealing with the cross-border agency problems that arise in supervising and resolving cross-border banking groups in the European Union (EU). The authors assume that PCA policies have been implemented by the national supervisors and explore the institutional changes needed in Europe if PCA is to be effective as an incentive compatible mechanism. The paper identifies these changes starting with enhancements in the availability of information on banking groups to supervisors. Next, the paper considers the collective decision making by supervisors with authority to make discretionary decisions within the PCA framework as soon as a bank of a cross-border banking group falls below the minimum capital standard. Finally, the paper analyzes the coordination measures that should be implemented if PCA requires the bank to be resolved.     

Deposit insurance and subsidized recapitalizations

The 2007–2009 financial crisis saw a vast expansion in deposit insurance guarantees around the world and yet our understanding of the design and consequences of deposit insurance schemes is in its infancy. We provide a new rationale for the provision of deposit insurance. In our model the banking sector exhibits both adverse selection and moral hazard, which implies that the social benefits of bank monitoring must for incentive reasons be shared between depositors and banks. Consequently, socially too few deposits are made in equilibrium. Deposit insurance – or, equivalently, bank recapitalization – corrects this market failure. We find that deposit insurance should be funded not by banks or depositors but out of general taxation. The optimal level of deposit insurance varies inversely with the quality of the banking system. Hence, when the soundness of the financial sector is uncertain, governments should consider supporting deposit insurance schemes and undertaking subsidized recapitalizations.     

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.     

The Taxation of Banking in an Integrating Europe

The banking sector is subject to explicit taxation and to bank regulation and supervision with quasi-fiscal implications. The assignment of national fiscal policy rights and duties regarding international banks in the EU varies with the fiscal instrument and with whether the international bank owns foreign branches or subsidiaries. Decentralized national policy-making in the EU gives rise to fiscal burdens on banks that differ internationally and with the national origin of banks in the same country. This paper discusses the international aspects of the overall fiscal regime facing banks in the EU and it evaluates some avenues for reform.     

What do premiums paid for bank M&As reflect? The case of the European Union

We analyze the takeover premiums paid for a sample of domestic and cross-border bank takeovers in the European Union between 1997 and 2007. We find that acquiring banks value profitable, high-growth and low risk targets. We also find that the strength of bank regulation and supervision as well as deposit insurance regimes in Europe have measurable effects on takeover pricing. Stricter bank regulatory regimes and stronger deposit insurance schemes lower the takeover premiums paid by acquiring banks. This result, presumably in anticipation of higher compliance costs, is driven by domestic deals. Similar qualitative results are found for both the entire sample and the sample of publicly traded targets.     

The spread of deposit insurance and the global rise in bank asset risk since the 1970s

We construct a new measure of deposit insurance generosity for many countries, empirically model the exogenous international influences on the adoption and generosity of deposit insurance and use a novel econometric method to explore the causal chain from the expansion of deposit insurance generosity to increased overall lending, increased lending to households, increased banking system leverage, and more severe and frequent banking crises. Greater deposit insurance generosity robustly produces greater overall lending relative to bank assets and more lending to households relative to both bank assets and GDP, and results in higher banking system leverage. Our estimates, however, are not conclusive regarding whether greater deposit insurance generosity resulted in greater total loans relative to GDP or in more frequent or severe banking crises.     

Do weak supervisory systems encourage bank risk-taking?

Weak bank supervision could give banks the ability to shift risk from themselves to supervisors. We use cross-border bank mergers as a natural experiment to test changes in risk and the impact of supervision. We examine cross-border bank mergers and find that the supervisory structures of the partners’ countries influence changes in post-merger total risk. An acquirer from a country with strong supervision lowers total risk after a cross-border merger. However, total risk increases when the target bank is located in a country with relatively strong supervision. This result is consistent with strong host regulators limiting the risky activities of their local banks. Foreign-owned competitors could then engage in the risky projects, especially if the foreign banks’ supervisors are not strong. An acquirer entering a country with strong supervision appears to shift risk back to its home country. The results suggest that bank supervisors can reduce total banking risk in their countries by being strong.
