银行盈利的宏微观因素——对中国银行业的实证研究

This paper seeks to examine the determinants of the profitability of the Chinese banking sector during the post-reform period of 2000–2005. The empirical findings from this study suggest that all the determinants variables have statistically significant impact on China banks profitability. However, the impacts are not uniform across bank types. We find that liquidity, credit risk, and capitalization have positive impacts on the state owned commercial banks (SOCBs) profitability, while the impact of cost is negative. Similar to their SOCB counterparts, we find that joint stock commercial banks (JSCB) with higher credit risk tend to be more profitable, while higher cost results in a lower JSCB profitability levels. During the period under study, the empirical findings suggest that size and cost results in a lower city commercial banks (CITY) profitability, while the more diversified and relatively better capitalized CITY tend to exhibit higher profitability levels. The impact of economic growth is positive, while growth in money supply is negatively related to the SOCB and CITY profitability levels.      

Charter value,risk-taking and systemic risk in banking before and after the global financial crisis of 2007-2008

ABSTRACT

We investigate how bank charter value affects risk for a sample of OECD banks by using standalone and systemic risk measures before, during, and after the global financial crisis of 2007–2008. Prior to the crisis, bank charter value is positively associated with risk-taking and systemic risk for very large ‘too-big-too-fail’ banks and large U.S. and European banks but such a relationship is inverted during and after the crisis. A deeper investigation shows that such a behaviour before the crisis is mostly relevant for very large banks and large banks with high growth strategies. Banks’ business models also influence this relationship. We find that for banks following a focus strategy, higher charter value amplifies both standalone and systemic risk for large U.S. and European banks. Our findings have important policy implications and cast doubts on the relevance of the uniform more stringent capital requirements introduced by Basel III.     

HOW DID STATE‐OWNED BANKS RESPOND TO PRIVATIZATION? EVIDENCE FROM THE INDIAN EXPERIMENT

ABSTRACT ** : The paper examines the response of banks to privatization. Using data on all state‐owned banks for the period 1990–2006, the findings indicate that fully state‐owned banks are significantly less profitable than partially privatized ones. The improvements in performance by partially privatized banks are, in fact, sustained after privatization. In addition, the analysis indicates that privatization improves profitability, efficiency and improves bank soundness, while lowering bank risk. While the improvement in bank risk is typically spread out over a much longer period, the progress in terms of profitability and economic efficiency typically occurs in the post‐privatization period.     

Too-Big-To-Fail: Why Megabanks Have Not Become Smaller Since the Global Financial Crisis?

ABSTRACT

More than ten years after the global financial crisis, what has happened to the ‘too-big-to-fail’ (TBTF) banks whose reckless behavior was among its preconditions, but which received public support and guarantees in the midst of that crisis? Insofar as this too-big-to-fail status helped create the crisis and then imposed costs on the rest of society, we would expect these banks to have shrunk. We investigate the evolution of 31 global-TBTF banks and find that their overall size has hardly recorded any substantial change. However, there is no sense of urgency in the flourishing post-crisis literature on TBTF banks about the need to contain their size; the prevalent view therein is that if properly regulated, the risks that arise from a financial system dominated by TBTF banks are manageable. This view rests on the same overly narrow theoretical underpinnings whose flaws were exposed in the crisis. We argue that too-big-to-fail banking is embedded in a set of self-reinforcing policies—consolidation, balance-sheet support through quantitative easing, favorable regulations, bank lobbying, and geo-economic and geo-political considerations—which explain why these banks have not shrunk and why they remain a threat to financial stability, well after the lessons of the crisis should have been learned.     

The Institutional Quality Effect on Credits Provided by the Banks

Research on developing economies is deficient in analysing institutional quality dimensions that are beyond standard determinants of the provision of credits by banks. This study fills this gap by adopting a broad-based modelling approach in examining the effects of institutional quality on credit provided by banks for a large sample of developing economies. A structural model, including balanced annual panel data from the World Bank World Development Indicators and Worldwide Governance Indicators for the period 2004 to 2017, was estimated using panel-corrected standard errors and two-stage least squares estimation techniques. The core variables determining the credit provided by banks were controlled for in the estimation phase. The findings showed that the rule of law, regulatory quality and the strength of legal systems are significant determinants of credit provided by banks, among other factors. Investments in improving institutional quality can be beneficial for credit diffusion by the banks. This study is distinct from previous empirical studies of the developing economies as it directs attention to institutional quality measures on bank credit expansion in an inclusive modelling framework. It makes a significant positive contribution to the finance institutional nexus literature in terms of understanding the value and role that institutional quality plays in fostering bank credit provision in developing economies.

     

Management Behaviour in Vietnamese Commercial Banks

This study identifies managerial behaviour in Vietnamese banks between the years 2000 and 2014, based on the managerial framework of banks, as identified by Rossi et al. ( 2009 ). This framework is built on the interrelationships between efficiency, risk, capital and diversification. This study uses the Z‐score to measure insolvency risk, the SFA to estimate cost efficiency, the ratio of total equity to total assets to capture bank capital and the HHI index to measure the diversification of revenue and earning assets. The results from the 3SLS estimator indicate that revenue diversification has an insignificant impact on insolvency risk, capital ratio and cost efficiency, but earning assets diversification has a negative effect on these three variables, supporting ‘classical diversification’, ‘economic capital’ and ‘monitoring’ behaviours. Moreover, a decline in cost efficiency leads to a rise in insolvency risk, implying ‘bad management’ behaviour; an increase in risk results in a reduction in cost efficiency, indicating ‘bad luck’ behaviour; and a reduction in capital ratio in the poorly capitalised banks leads to a growth in risk, suggesting ‘moral hazard’ behaviour. The results remain strongly robust when using an alternative risk measurement (the loan loss provision ratio) and an alternative SFA model.     

The supply of and demand for accounting information

The article analyzes the use of accounting information in Russia. We assess reporting behaviour in the lending process for a sample of Russian companies in the years 1999–2004 and postulate that Russian companies manage their earnings in order to avoid showing losses when applying for bank financing. Once a credit has been granted, companies are predicted to manage earnings because of the bank's monitoring activities. By means of univariate and multivariate analysis we are able to attribute the discontinuity around a zero target in the earnings distribution with firms’ response to the banks’ assessment of accounting performance. This implies that financing considerations affect the reporting incentives of Russian companies.     

Determinants of bank cost efficiency in transition economies: evidence for Latin America,Central and Eastern Europe and South-East Asia

In this study, we adopt Wang’s (2002) heteroscedastic stochastic frontier model, which allows us to investigate bank cost efficiency and to measure the marginal effects of some variables on both the level and the variability of inefficiency. In recent years, the financial crisis has significantly affected the banking systems of the transition countries. Hence, the efficiency is of major importance for the stability of the banks. Regarding the determinants of efficiency, we find evidence that banks that follow a more cautious strategy, characterized by lower risk appetite and average expectations on profitability, have higher cost efficiency. We also find that traditional deposit-taking and loan-making still remain the most efficient activity of the banks. Additionally, the results showed that a higher Gross Domestic Product growth rate implies an increase in the inefficiency level, indicating an unsustainable bank management behaviour, which in periods of economic growth adopts policies that can generate inefficiency in order to gain market share and to obtain higher bonuses. Country cost efficiency results show significant differences. The banking systems in transition countries in South Eastern Asia appear to have a higher cost efficiency level. Also, the effects of the financial crisis were less significant in this region.     

Global banking,global crises? The role of the bank balance-sheet channel for the transmission of financial crises

We examine whether shocks to leveraged creditors with cross border holdings have an incidence on debtor countries׳ risk of suffering financial turmoil. We construct a new proxy of shocks to international banks׳ balance-sheets using credit ratings and the structure of their international assets. This allows us investigating the effect of (foreign) bank balance-sheet shocks on domestic financial turmoil in a large sample of 146 developed and emerging economies from 1984 to 2011. Our proxies of shocks towards bank balance-sheets are strong predictors of systemic banking crises in their debtor countries. Confirming these results, bilateral bank flows significantly decrease when creditor banks׳ assets are hit by negative shocks, as measured by credit rating downgrades from third-party countries. Short-term liabilities towards global banks appear to increase roll-over and funding risks, thereby amplifying the impact of shocks to foreign lenders’ balance-sheets. Domestic banking sectors vulnerabilities, such as illiquid assets and a low deposit-asset ratio, are found to increase crisis contagion risk. In contrast, a high level of global liquidity attenuates the transmission of shocks to international banks׳ assets to debtor countries.     

Bank profitability and macroeconomic conditions: Are business models different?

The paper investigates the impact of macroeconomic conditions on the profitability of EU banks by testing for differential effects according to the business model. We group banks into three business models using a hierarchical cluster analysis and find that using clusters based on the share of assets invested in loans reveals heterogeneity in the sensitivity of bank profitability to economic growth across business models. Our main result is that GDP growth, credit growth, and the risk-free yield curve influence profitability as expected, but we also find that the effect of GDP growth is only significant for banks that have a high and medium share of assets invested in loans, and not for banks that hold large portfolios of securities. This difference depends on the impact of growth on asset write downs, especially those on loans and, to a lesser extent, on revenues. The results suggest that studies relating bank profitability to macroeconomic conditions should take the heterogeneity of business models into account.     

Economic effects of positive credit information sharing: the case of Korea

In many countries, in addition to negative credit information such as loan default and arrears, positive credit information is also exchanged on a voluntary and reciprocal basis. Employing optimal credit decision models of profit maximizing banks, and utilizing a unique dataset of 2?million consumer loan obligors in Korea, we investigate the economic effects of sharing positive credit information in addition to negative credit information already exchanged. We find that the discriminatory power of the credit scoring model improves significantly. We proceed to investigate the economic effects of the information gap in a competitive credit market by assuming two representative banks that differ only in the level of credit information sharing. The bank that utilizes negative information only suffers from deterioration of the borrower pool and reduced profit, as high credit risk borrowers are more concentrated on this bank due to underpricing of risks. Our finding suggests that banks have incentives to voluntarily participate in the positive information sharing mechanism, since even a small difference in discriminatory power stemming from the information gap may lead to a significant fall in profitability as the distribution of borrower quality changes endogenously due to adverse selection problems.     

Social aspirations in European banks: peer-influenced risk behaviour

We test a sample of 3,586 banks from 33 European countries to determine whether performances above or below a social aspiration level (median performance of peer banks) influence banks’ aggregate risk levels. Our results are consistent with the behavioural theory of the firm and prospect theory in that we find that bank performance below a bank’s social aspiration level is followed by increased aggregate risk, i.e. risk-taking behaviour in the subsequent year. Although under-performing banks tend to be risk-takers, large banks and banks with high aggregate risk levels tend to limit the increase in their aggregate risk levels.     

WINDOW GUIDANCE BY THE BANK OF JAPAN: WAS LENDING CONTROLLED?

Over the period 1961–1991, the Bank of Japan (BOJ) attempted to directly control the volume of commercial bank credit by providing lending targets for selected banks. This policy of “window guidance” (WG) applied to only a subset of lending institutions. The guided banks involved were under no legal obligation to heed the BOJ's requests. Using actual WG data to city banks, two questions are addressed. First, did city banks comply with WG (the “compliance hypothesis”)? Second, was WG successful in controlling economywide lending or did lending adjustments by other financial institutions simply displace the lending of guided banks (the “displacement hypothesis”)? The empirical results show a high degree of compliance in the first two decades of the program and evidence of weakening in the final years. The displacement hypothesis is rejected, particularly in the early period of highly regulated financial markets. (JEL E58, E51, E52)     

Microeconomic determinants of acquisitions of Eastern European banks by Western European banks1

A considerable number of Western European banks acquired banks in Central and Eastern Europe from the mid‐1990s onwards. The question is whether or not this will improve the efficiency and profitability of the Central and Eastern European banking sectors. We test the relative strength of the efficiency versus the market power hypotheses by investigating the bank‐specific characteristics of the banks involved in the cross‐border acquisitions. We also examine the determinants of the post‐acquisition target banks’ performance. Our results indicate that large Western European banks have targeted relatively large and efficient Central and Eastern European countries (CEEC) banks with an established presence in their local retail banking markets. We find no evidence that cross‐border bank acquisitions in the CEEC are driven by efficiency motivations. The evidence supports the market power hypothesis, raising concerns about the optimal balance between foreign ownership and competition.     

The link between the federal funds rate and banking system distress: An empirical investigation

We investigate the association between deviations of the monetary policy rate from its benchmark, and systemic risk between 2001 and 2017. We adopt an impulse response function framework that uses the local projections method model proposed by Jorda (2005). We find that paying interest on reserves by the Fed beginning in 2008 introduced a monetary policy regime shift between the period that the Fed did not pay interest on reserves and the period that it did. Consequently, while we identify a positive and significant link between deviations of the policy rate from its benchmark and systemic risk in the former period, this link was broken in the latter period. During the former period, upsurges in the fed funds rate raised bank costs and increased bank distress. In contrast, during the latter period, interest payment on reserves exceeded the policy rate, except for 2009Q1, and as a result, banks did not expand lending in response to the Fed's reserve injections, instead, holding large amounts of excess reserves. This practice produced greater bank profitability and reduced bank liquidity risk and credit risk, without increasing systemic risk.     

Standby Letters of Credit and Bank Default Risk

This paper examines the relationship between Australian banks' use of standby letters of credit, an off-balance sheet direct credit sub stitute, and default risk on bank liabilities. We find strong support for the sub-optimal investment (or under-investment) hypothesis. Riskier banks, defined as those with higher CD premiums, and those with higher proportions of long-maturity liabilities make greater use of SLCs than less risky banks. However, there is little evidence of a feed-back effect from SLCs to bank default risk     

Monetary policy and bank lending in a low interest rate environment: Diminishing effectiveness?

This paper analyses the effectiveness of monetary policy on bank lending in a low interest rate environment. Based on a sample of 108 large international banks, our empirical analysis suggests that monetary policy is less effective in stimulating bank lending growth when interest rates reach a very low level. This result holds after controlling for business and financial cycle conditions and different bank-specific characteristics such as liquidity, capitalisation, funding costs, bank risk and income diversification. We find that the impact of low rates on the profitability of banks’ traditional intermediation activity helps explain the subdued evolution of lending in the period 2010–14.     

The determinants and profitability of switching costs in Chinese banking

This article models the determinants of bank switching costs in China in terms of bank characteristics and non-bank variables. It also determines the contribution of switching costs to banks’ profits. Using a sample of 151 banks over the period 2003–2013 it reports a positive relationship between bank profitability and switching costs. The main result is that bank size measured by total assets has a complex relationship with switching costs. Competition between small banks creates the incentive for lock-in and increased switching costs whereas very large banks are less exercised by lock-in and switching costs.     

Large lending and banks performance. Is there any relationship? Empirical evidence from US banks

Large lending in the banking industry has sparked concerns about banks’ efficiency performance, particularly, if it is related to their credit risk, as trade credit, provided by large, creditworthy firms. We provide evidence of a rather neglected issue regarding the impact of large lending on banks’ efficiency using cost and profit stochastic functions. A unique dataset was constructed concerning all US banks collected from the Statistics on Depository Institutions report compiled by the Federal Deposit Insurance Corporation. Our sample contains US banks tracked yearly for the period 2010–2017, creating an unbalanced panel of year observations. An econometric framework based on nested non-neutral frontiers was developed to estimate the influence and the decomposition of large lending on the three banks’ performance aspects. Moreover, different types of frontiers aiming at the cost and profit sides have been investigated, and the associated elasticities have been calculated. We notice that large lending plays a crucial role in banks’ technical efficiency. Variations among different frontier models, type of bank and size, banks’ ownership structure, and macroeconomic conditions appear to be present. By considering all capital adequacy asset quality management earnings liquidity parameters, we notice that banks’ financial strength affects banks’ efficiency.     

Current Account Imbalances or Too Much Bank Debt as the Main Driver of Gross Capital Inflows? Spain During the Great Financial Crisis

Abstract:

In contrast to the widespread view which posits that large current account deficits and net international debt were at the epicenter of the crisis in the Euro Zone, with diverging competitiveness playing a central role, this article points to the huge volume of bank credit that banks refinanced in international markets.

With a focus on the Spanish economy, we ground our view in an analysis linking gross—not net—capital flows, bank credit, and gross external debt, which provides more adequate information about a country’s international financing patterns and its external exposure.

The main conclusion of this article is that the principle driver of gross external debt in Spain was bank credit, with accumulated current account deficits accounting for less than 50 percent of gross external debt. Other consequences in keeping with this view are: the measures of economic policy required to sort out current account imbalances—particularly wage devaluation to improve competitiveness—may do more harm than good and they do not prevent the problem of too much bank credit from occurring again, and the residence of debt holders in the Euro Zone crisis is relevant for the understanding of the crisis as the result of a power imbalance
