Financial supervision regimes and bank efficiency: International evidence

There exists a lively debate as for the appropriate architecture of the financial supervision regime, with a long list of theoretical advantages and disadvantages associated with each one of its key dimensions. The present study investigates whether and how bank profit efficiency is influenced by the central bank’s involvement in financial supervision, the unification of financial authorities, and the independence of the central bank. The results show that efficiency decreases as the number of the financial sectors that are supervised by the central bank increases. Additionally, banks operating in countries with greater unification of supervisory authorities are less profit efficient. Finally, central bank independence has a negative impact on bank profit efficiency.     

Determinants of bank efficiency during unstable macroeconomic environment: Empirical evidence from Malaysia

The present study investigates for the first time the efficiency of Malaysian banking sector around the Asian financial crisis 1997. The efficiency estimates of individual banks are evaluated by using the Data Envelopment Analysis (DEA) approach. To examine the robustness of the estimated efficiency scores under various alternatives and to differentiate how efficiency scores vary with changes in inputs and outputs, the present study focuses on three major approaches viz., intermediation approach, value added approach, and operating approach. The analysis further links the variation in calculated efficiencies to a set of explanatory variables, i.e. bank size, profitability, and ownership. The empirical findings clearly bring forth the high degree of inefficiency in the Malaysian banking sector, particularly a year after the East Asian crisis. The results suggest that the decline in technical efficiency is more abrupt under the intermediation approach relative to the value added approach and operating approach. The regression results focusing on bank efficiency and other bank specific traits suggest that efficiency is negatively related to expense preference behavior and economic conditions, while bank efficiency is positively related to loans intensity.     

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.     

Differential impact of Korean banking system reforms on bank productivity

We study the impact of banking system reforms during a crisis following a period of undisciplined lending. Regulatory changes aimed at strengthening the banks’ capital structure and risk management practices do not have a uniform impact on bank productivity, but rather favor financially sound or strategically privileged banks. We present evidence documenting the differential impact of regulatory reforms on Korean commercial bank productivity over the period 1995–2005. Average technical efficiency of banks decreased during the financial crisis of 1997–1998. It improved following the subsequent bank restructuring and continued to improve through 2005. The capital adequacy ratio is positively associated with banks’ technical efficiency. The non-performing loans ratio is negatively associated with technical efficiency. Both relationships are accentuated during the crisis but attenuated after the reforms.     

The impact of European bank mergers on bidder default risk

We analyze the implications of European bank consolidation on the default risk of acquiring banks. For a sample of 134 bidding banks, we employ the Merton distance to default model to show that, on average, bank mergers are risk neutral. However, for relatively safe banks, mergers generate a significant increase in default risk. This result is particularly pronounced for cross-border and activity-diversifying deals as well as for deals completed under weak bank regulatory regimes. Also, large deals, which pose organizational and procedural hurdles, experience a merger-related increase in default risk. Our results cast doubt on the ability of bank merger activity to exert a risk-reducing and stabilizing effect on the European banking industry.     

Towards a more accurate measure of foreign bank entry and its impact on domestic banking performance: The case of China

This paper examines the impact of foreign bank entry on China’s banking performance. An innovation in this study is that it constructs a spatially disaggregated measure of foreign bank presence, employing location data of foreign bank branches. Using this measure, the study examines the relationship between foreign bank presence and domestic banking performance in China. The results show that the spatially disaggregated measure not only improves the assessment of the impact of foreign bank presence but also resolves unexplained discrepancies found in existing empirical studies contingent on aggregate measures. Importantly, the study provides strong empirical evidence that foreign bank entry is supportive of a more competitive and efficient banking industry in China.     

Financial freedom and bank efficiency: Evidence from the European Union

This paper investigates the dynamics between the financial freedom counterparts of the economic freedom index drawn from the Heritage Foundation database and bank efficiency levels. We rely on a large sample of commercial banks operating in the 27 European Union member states over the 2000s. After estimating bank-specific efficiency scores using Data Envelopment Analysis (DEA), we develop a truncated regression model combined with bootstrapped confidence intervals to test our main hypotheses. Results suggest that the higher the degree of an economy’s financial freedom, the higher the benefits for banks in terms of cost advantages and overall efficiency. Our results also show that the effects of financial freedom on bank efficiency tend to be more pronounced in countries with freer political systems in which governments formulate and implement sound policies and higher quality governance.     

The determinants of bank loan recovery rates

Using Moody’s Ultimate Recovery Database, we estimate a model for bank loan recoveries using variables reflecting loan and borrower characteristics, industry and macroeconomic conditions, and several recovery process variables. We find that loan characteristics are more significant determinants of recovery rates than are borrower characteristics prior to default. Industry and macroeconomic conditions are relevant, as are prepackaged bankruptcy arrangements. We examine whether a commonly used proxy for recovery rates, the 30-day post-default trading price of the loan, represents an efficient estimate of actual recoveries and find that such a proxy is biased and inefficient.     

The cyclical behaviour of European bank capital buffers

Using an unbalanced panel of accounting data from 1997 to 2004 and controlling for individual bank costs and risk, we find capital buffers of the banks in the EU15 have a significant negative co-movement with the cycle. For banks in the accession countries there is significant positive co-movement. Capital buffers of commercial and savings banks, and of large banks, exhibit negative co-movement. Those of co-operative and smaller banks exhibit positive co-movement. Speeds of adjustment are fairly slow. We interpret these results and discuss policy implications, noting that negative co-movement of capital buffers will exacerbate the pro-cyclical impact of Basel II.     

The liquidity of bank assets and banking stability

This paper shows that an increased liquidity of bank assets, paradoxically, increases banking instability and the externalities associated with banking failures. This is because even though higher asset liquidity directly benefits stability by encouraging banks to reduce the risks on their balance sheets and by facilitating the liquidation of assets in a crisis, it also makes crises less costly for banks. As a result, banks have an incentive to take on an amount of new risk that more than offsets the positive direct impact on stability.     

The effects of reform on China’s bank structure and performance

This paper investigates the relationship between market structure and performance in China’s banking system from 1985 to 2002, a period when this sector was subject to gradual but notable reform. Using panel data estimation techniques, both the market-power and efficient-structure hypotheses are tested. In addition, the model is extended to consider issues such as the impact of bank size/ownership and whether the big four banks enjoy a “quiet life”. On average, X-efficiency declined significantly and most banks were operating below scale efficient levels. Estimation of the structure–performance models lends some support to the relative market-power hypothesis in the early period. The reforms had little impact on the structure of China’s banking sector, though the “joint stock” banks became relatively more X-efficient. There was no evidence to support the quiet-life hypothesis, probably because strict interest rate controls prevented the state banks from earning monopoly profits. Thus the ongoing liberalisation of interest rates should be accompanied by reduced concentration. Overall, to improve competitive structure, new policies should be directed at encouraging market entry and increasing the market share of the most efficient banks.     

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.     

Understanding the rise and decline of the Japanese main bank system: The changing effects of bank rent extraction

This paper shows how main bank rent extraction affects corporate decisions about investment and financing during financial regulatory reform. Our model predicts that limited loanable funds can initially contain main bank controlled overinvestment, even when new equity is available to the firm. Abundant funds facilitate overinvestment to the detriment of firm profitability. A shift of control rights back to the firm due to financial deregulation produces an “equity for upside potential and bank debt for downside risk” bias against the banks. A stock market and real estate boom in Japan made it harder than ever for the banks to diversify risk. The insights from this analysis help explain why Japan’s main bank system was beneficial in the (capital constrained) postwar period but became harmful during the (capital abundant and even bubbly) 1980s, and why the adverse shocks of the post-deregulation 1990s had such severe effects on the banking system.     

The effects of focus versus diversification on bank performance: Evidence from Chinese banks

This paper investigates the effects of focus versus diversification on bank performance using data on Chinese banks during the 1996–2006 period. We construct a new measure, economies of diversification, and compare the results to those of the more conventional focus indices, which are based on the sum of squares of shares in different products or regions. Diversification is captured in four dimensions: loans, deposits, assets, and geography. We find that all four dimensions of diversification are associated with reduced profits and higher costs. These results are robust regardless of alternative measures of diversification and performance. Furthermore, we observe that banks with foreign ownership (both majority and minority ownership) and banks with conglomerate affiliation are associated with fewer diseconomies of diversification, suggesting that foreign ownership and conglomerate affiliation may play important mitigating roles. This analysis may provide important implications for bank managers and regulators in China as well as in other emerging economies.     

How bank capital buffers vary across countries: The influence of cost of deposits,market power and bank regulation

This paper analyzes the bank and country determinants of capital buffers using a panel data of 1337 banks in 70 countries between 1992 and 2002. After controlling for adjustment costs and the endogeneity of explanatory variables, the results show that capital buffers are positively related to the cost of deposits and bank market power, although the relations vary across countries depending on regulation, supervision, and institutions. Their impact is the result of two generally opposing effects: restrictions on bank activities and official supervision reduce the incentives to hold capital buffers by weakening market discipline, but at the same time they promote higher capital buffers by increasing market power. Institutional quality has the two opposite effects. Better accounting disclosure and less generous deposit insurance, however, have a clear positive effect on capital buffers by both strengthening market discipline and making charter value better able to reduce risk-taking incentives.     

Do cross-country differences in bank efficiency support a policy of “national champions”?

As banking consolidation proceeds and Europe moves toward a single market, cross-country differences in banking efficiency can affect the future competitive position of a country’s financial market, helping to determine which European money centers may expand or contract. Looking at large banks across 10 countries, we find they are roughly equally efficient after controlling for differences in business environment, banking costs, and bank productivity. As no country seems to have a strong efficiency advantage, it seems likely that state efforts to promote “national champions” through favorable mergers which expand scale and market share may determine the outcome.     

Market discipline during crisis: Evidence from bank depositors in transition countries

The Central European banking industry is dominated by foreign-owned banks. During the recent crisis, for the first time since the transition, foreign parent companies were frequently in a worse financial condition than their subsidiaries. This situation created a unique opportunity to study new aspects of market discipline exercised by non-financial depositors. Using a comprehensive data set, we find that the recent crisis did not change the sensitivity of deposit growth rates to accounting risk measures. We establish that depositors’ actions were more strongly influenced by negative press rumors concerning parent companies than by fundamentals. The impact of rumors was especially perceptible when rumors turned out ex post to be founded. Additionally, we document that public aid announcements were primarily interpreted by depositors as confirmation of a parent company’s financial distress. Our results indicate that depositors react rationally to sources of information other than financial statements; this discovery has policy implications, as depositor discipline is usually the only viable and universal source of market discipline for banks in emerging economies.     

Foreign bank entry,credit allocation and lending rates in emerging markets: Empirical evidence from Poland

Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.     

Bank activity and funding strategies: The impact on risk and returns

This paper examines the implications of bank activity and short-term funding strategies for bank risk and return using an international sample of 1,334 banks in 101 countries leading up to the 2008 financial crisis. Expansion into noninterest income-generating activities such as trading increases the rate of return on assets, and it could offer some risk diversification benefits at very low levels. Nondeposit, wholesale funding in contrast lowers the rate of return on assets, while it can offer some risk reduction at commonly observed low levels of nondeposit funding. A sizable proportion of banks, however, attract most of their short-term funding in the form of nondeposits at a cost of enhanced bank fragility. Overall, banking strategies that rely prominently on generating noninterest income or attracting nondeposit funding are very risky, consistent with the demise of the US investment banking sector.     

A geographically weighted approach to measuring efficiency in panel data: The case of US saving banks

This paper discusses a new approach to controlling for the environment when estimating efficiency. In response to the literature on the international comparison of bank efficiency, we draw the attention to a local dimension of comparison. By introducing geographical weights and estimating local frontiers for each US savings bank in the 2001–09 period, we find that the bank technical performance is higher for most banks in comparison to a fixed-effects approach. This result highlights the importance of taking into account the local environment and constraints while analyzing banks’ performance, so as not to consider the factors that are exogenous to these institutions as inefficiencies. Further analysis could improve the weighs calculation by employing other measures of interconnectedness besides geographical distance.
