Do bank regulation,supervision and monitoring enhance or impede bank efficiency?

The recent global financial crisis has spurred renewed interest in identifying those reforms in bank regulation that would work best to promote bank development, performance and stability. Building upon three recent world-wide surveys on bank regulation (,  and ), we contribute to this assessment by examining whether bank regulation, supervision and monitoring enhance or impede bank operating efficiency. Based on an un-balanced panel analysis of 4050 banks observations in 72 countries over the period 1999–2007, we find that tighter restrictions on bank activities are negatively associated with bank efficiency, while greater capital regulation stringency is marginally and positively associated with bank efficiency. We also find that a strengthening of official supervisory power is positively associated with bank efficiency only in countries with independent supervisory authorities. Moreover, independence coupled with a more experienced supervisory authority tends to enhance bank efficiency. Finally, market-based monitoring of banks in terms of more financial transparency is positively associated with bank efficiency.     

The impact of banking regulations on banks' cost and profit efficiency: Cross-country evidence

This paper uses stochastic frontier analysis to provide international evidence on the impact of the regulatory and supervision framework on bank efficiency. Our dataset consists of 2853 observations from 615 publicly quoted commercial banks operating in 74 countries during the period 2000-2004. We investigate the impact of regulations related to the three pillars of Basel II (i.e. capital adequacy requirements, official supervisory power, and market discipline mechanisms), as well as restrictions on bank activities, on cost and profit efficiency of banks, while controlling for other country-specific characteristics. Our results suggest that banking regulations that enhance market discipline and empower the supervisory power of the authorities increase both cost and profit efficiency of banks. In contrast, stricter capital requirements improve cost efficiency but reduce profit efficiency, while restrictions on bank activities have the opposite effect, reducing cost efficiency but improving profit efficiency.     

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.     

Politicians and financial supervision unification outside the central bank: Why do they do it?

An increasing number of countries show a trend towards a certain degree of consolidation of powers in financial supervision, which has resulted in the establishment of unified regulators, that are different from the national central banks. By contrast a high involvement of the central bank in supervision seems to be correlated with a multi-authorities regime (central bank fragmentation effect). This paper, using a simple application of a general common agency game, sheds light on which conditions the politicians prefer when implementing an unified sector supervision outside the central bank. From a theoretical point of view the quality of public sector governance plays a crucial role in determining the supervision unification. Focusing on the behaviour of the “good” policymaker (helping hand type), it will prefer a unified financial authority that is different from the central bank if the correspondent welfare gains-linked to at least one of the three effects: moral hazard, conflict of interest, bureaucracy—are considered higher respect to the information losses. The “bad” policymaker (grabbing hand type) will choose the single financial authority if the financial industry likes it, and the central bank is not a captured one. On the other hand, the paper tests the model, confirming the robustness of the institutional position of the central bank in explaining the recent trend in supervision consolidation, with an empirical analysis performed with ordered functions on an updated dataset.     

The impact of non-traditional activities on the estimation of bank efficiency: International evidence

This paper investigates the relevance of non-traditional activities in the estimation of bank efficiency levels using a sample of 752 publicly quoted commercial banks from 87 countries around the world, allowing comparison of the impact of such activities under different levels of economic development, geographical regions and other country characteristics. We estimate both cost and profit efficiency of banks using a traditional function that considers loans and other earnings assets as the only outputs, and two additional functions to account for non-traditional activities, one with off-balance sheet (OBS) items and the other with non-interest income as an additional output. Controlling for cross-country differences in regulatory and environmental conditions, we find that, on average, cost efficiency increases irrespective of whether we use OBS or non-interest income, although the results for profit efficiency are mixed. Our results also reveal that while the inclusion of non-traditional outputs does not alter the directional impact of environmental variables on bank inefficiency, regulations that restrict bank activities and enhance monitoring and supervision provisions improve both cost and profit efficiency.     

Two Naked Emperors?* Concerns about the Stability & Growth Pact and Second Thoughts about Central Bank Independence

This paper addresses two sets of issues relevant to current and prospective future E(M)U members: the consequences of the Stability & Growth Pact for fiscal‐financial sustainability and macroeconomic stability, and some risks associated with operational independence of the central bank. To be effective as a lender of last resort or to stabilise demand when short nominal interest rates are close to their zero lower bound, the central bank must coordinate and cooperate with the fiscal authorities. Central bank independence is unlikely to survive if such coordination and cooperation are not forthcoming.     

关于中央银行金融监管权边界的理论思考

中央银行应在多大程度上行使金融监管职能,长期以来一直是个理论上有争议的问题,在各国金融监管实践中也表现出不同的情况。然而,此次金融危机后,许多国家出台的金融监管体制改革方案都主张扩大中央银行的监管权限。本文拟对中央银行扩权的主要依据进行理论分析,并对我国金融监管框架的改革提一些建议。     

The central banker as prudential supervisor: Does independence matter?

We study whether central bank independence (CBI) and monetary policy arrangements can jointly influence the likelihood of policymakers assigning banking supervision to central banks. Our empirical analysis shows that, assuming a benevolent government, a higher degree of central bank operational (economic) independence is associated with a lower probability of supervisory powers being entrusted to the monetary authority. We interpret this result as deriving from governments’ fear of the risk of excessively discretionary monetary policy. However, there is evidence that – conditional on operational independence – central banks are more involved in supervision when they pursue tighter monetary policy goals (a specific aspect of political independence). Our interpretation is that the latter may represent a commitment to mitigate central banks’ discretion in the monetization of financial distress. Our study suggests that CBI can be relevant, not only for its alleged effects on macroeconomic variables, but also in influencing policymakers’ decisions on the allocation of banking supervisory powers.     

On the implications of market power in banking: Evidence from developing countries

This paper investigates how different degrees of market power affect bank efficiency and stability in the context of developing economies. It sheds light on the competition-stability nexus by documenting and analyzing the complex interactions between a tripod of variables that are central for regulators: the degree of market power, bank cost and profit efficiency, and overall firm stability. The results show that an increase in the degree of market power leads to greater bank stability and enhanced profit efficiency, despite significant cost efficiency losses. The findings lend empirical justification to the traditional view that increased competition may undermine bank stability, and may bear significant implications for stressed banking systems in developing economies.     

The future and dynamics of global systemically important banks

The purpose of this paper is to analyse some of the issues associated with supervision and regulation of global systemically important banks, G-SIB. The paper highlights the importance of managing liquidity risk and creating a global financial system that can minimise regulatory arbitrage by large financial institutions. The paper argues that, unlike some industries such as the airline industry in which risk has been contained and yet the size and capacity of aircrafts have increased, in the banking system, less progress has been made to contain financial risk and allow large banks to expand their global activities. The paper argues that G-SIB are able to continue remaining large provided that a globally integrated financial system ensures effective global supervision of these large banks. The paper compares the US banking crises in the 19th century and the subsequent emergence of the US Federal Reserve System to the possibility of establishing a world central bank and a global supervisory board. Such new global institutions will have the capacity to reduce regulatory arbitrage, increase effective supervision, reduce systemic and liquidity risk and create a more stable global financial system.     

Financial liberalisation,crisis, and restructuring: A comparative study of bank performance and bank governance in South East Asia

This paper examines the impact of changes in bank governance on bank performance for a sample of commercial banks operating in SE Asia between 1990 and 2003. We identify bank governance in terms of bank ownership and measure bank performance as rank order alternative profit efficiency, technical change, and productivity. The period was characterised by financial deregulation, the Asian crisis and bank restructuring programmes. To resolve financial distress, SE Asian authorities implemented inter alia bank privatisation programmes and widened access for foreign ownership. Our results tend to support bank privatisation and the repeal of state ownership on economic grounds. We suggest the potential benefits of foreign ownership may take longer to be realised. For domestic private-owned banks, the challenge is improving bank efficiency.

Cross-country determinants of bank income smoothing by managing loan-loss provisions

This paper studies the determinants of income smoothing by management of loan-loss provisions in banks around the world. Using a panel database of 3221 bank-year observations from 40 countries and controlling for unobservable bank effects and for the endogeneity of explanatory variables, we find that bank income smoothing depends on investor protection, disclosure, regulation and supervision, financial structure, and financial development. Results suggest there is less bank income smoothing not only with the strength of investor protection, but also with the extent of accounting disclosure, restrictions on bank activities, and official and private supervision, while there is more income smoothing with market orientation and development of a country’s financial system.     

Efficiency and risk in European banking

We assess the inter-temporal relationship between bank efficiency, capital and risk in a sample of European commercial banks employing several definitions of efficiency, risk and capital and using the Granger-causality methodology in a panel data framework. Our results suggest that lower bank efficiency with respect to costs and revenues Granger-causes higher bank risk and that increases in bank capital precede cost efficiency improvements. We also find that more efficient banks eventually become better capitalized and that higher capital levels tend to have a positive effect on efficiency levels. These results are generally confirmed by a series of robustness tests. The results have potentially important implications for bank prudential supervision and underline the importance of attaining long-term efficiency gains to support financial stability objectives.

Institutional structures of financial sector supervision,their drivers and historical benchmarks

This paper studies institutional structures of prudential and business conduct supervision of financial services in 98 high and middle income countries over the past decade. It identifies possible drivers of changes in these supervisory structures using the panel ordered probit analysis. The results show that (i) more developed, small open economies with better public governance tend to integrate their supervision, especially the prudential one; (ii) more financially developed countries integrate more their supervision; however, greater development of the non-bank financial system leads to less integrated prudential supervision but not business conduct supervision; (iii) the lobbying power of concentrated and highly profitable banking sectors significant hinders business conduct integration; (vi) countries that experienced financial crises integrate their supervisory structure relatively more and (v) greater central bank independence could cause less integration of prudential supervision, but not necessarily of business conduct supervision.     

Inflation targeting: Is IT to blame for banking system instability?

In light of the financial crisis, the practice of inflation targeting (IT) has been blamed for authorities’ failure to respond to the increase in financial systemic risk and to the development of asset bubbles. However, utilizing a rich database containing nearly 5500 commercial banks from 70 countries (among which, 22 are IT) for the period 1998–2012, this paper argues that on average, inflation targeting national banking systems (i) are more stable; (ii) possess sounder systemically important banks; and (iii) are less distressed than (or at least as distressed as) other banks during periods of global liquidity shortages. Our results are robust to a series of tests, such as when we compare countries with the same legal origins or control for the delegation of bank supervision responsibility to bodies other than the central bank. Overall, we conclude that IT cannot be blamed for contributing to financial fragility.     

Risk management,corporate governance,and bank performance in the financial crisis

The recent financial crisis has raised several questions with respect to the corporate governance of financial institutions. This paper investigates whether risk management-related corporate governance mechanisms, such as for example the presence of a chief risk officer (CRO) in a bank’s executive board and whether the CRO reports to the CEO or directly to the board of directors, are associated with a better bank performance during the financial crisis of 2007/2008. We measure bank performance by buy-and-hold returns and ROE and we control for standard corporate governance variables such as CEO ownership, board size, and board independence. Most importantly, our results indicate that banks, in which the CRO directly reports to the board of directors and not to the CEO (or other corporate entities), exhibit significantly higher (i.e., less negative) stock returns and ROE during the crisis. In contrast, standard corporate governance variables are mostly insignificantly or even negatively related to the banks’ performance during the crisis.     

Monetary policy games,financial instability and incomplete information

In the aftermath of the recent global financial crisis, monetary authorities, while pursuing traditional objectives, such as the control of inflation, are also eager to promote financial stability. In this paper, we model the strategic interaction of the central bank and the financial sector and explore a simple monetary policy game with perceived substantial risks to financial stability, where the central bank can be of two types, one pursuing strict inflation-targeting and the other concerned with affecting the expectations formed by the financial sector participants; however, the financial sector is unsure which, due to incomplete information. The conclusion is that for small shocks to inflation there is a pooling equilibrium, whereas for larger shocks there is separation. In the latter case, the central bank that has an explicit financial stability concern is willing to exercise more muted control to inflation in order to reinforce the safety of the financial sector.     

Do Markets Care about Central Bank Governor Changes? Evidence from Emerging Markets

Based on a new daily data set for 20 emerging markets over the period 1992–2006, we examine the reactions of foreign exchange markets, domestic stock markets, and sovereign bond spreads to central bank governor changes. We find that the replacement of a central bank governor negatively affects financial markets on the announcement day, which is in line with the hypothesis that newly appointed central bank governors suffer from a systematic credibility problem at the beginning of their tenure. We also find some evidence that changes in perceived central bank independence affect markets.
