In designing credit rating systems under the new Basel Accord, considerable effort has been devoted to rating assignment and quantification, while the choice of the optimal bucket structure has received less attention. To fill this gap, we propose two “bucketing” strategies based on constrained optimisation, paying attention to the implications of rating buckets for loan-pricing and adverse selection phenomena. We compare them with some more naïve approaches, based on a sample of about 100,000 European companies. We also analyse the persistence of our performance measures over time, as well as the effect of large exposures being associated with low-PD obligors. 相似文献

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. 相似文献

Existing studies suggest that systemic crises may arise because banks either hold correlated assets, or are connected by interbank lending. This paper shows that common regulation is also a conduit for interbank contagion. One bank's failure may undermine confidence in the banking regulator's competence, and, hence, in other banks chartered by the same regulator. As a result, depositors withdraw funds from otherwise unconnected banks. The optimal regulatory response to this behavior can be privately to exhibit forbearance to a failing bank. We show that regulatory transparency improves confidence ex ante but impedes regulators' ability to stem panics ex post. 相似文献

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. 相似文献

Based on a sample of 3254 floating rate tranches from 617 ABS-CDOs (collateralized debt obligations backed by asset-backed securities), this paper tests the “rating overdependence” hypothesis – i.e., that ratings of structured products are a sufficient statistic (in terms of predicting future credit performance) for yield spreads at origination. The paper’s findings are fourfold. First, yield spreads at issuance predict future performance of ABS-CDO tranches even after controlling for the information contained in ratings. Second, the ability of yield spreads to predict future performance, however, is driven exclusively by ratings below AAA (and, to a lesser extent, also by the lowest priority AAA tranches), whereas spreads of super senior AAA tranches show no information content. Third, the predictive ability of yield spreads is lower for tranches from later vintages and for tranches from deals with more complex collateral pools. Fourth, the conditional correlation between ratings and spreads, in turn, is increasing in time and higher for tranches from complex deals. In sum, the evidence indicates that investors in (especially AAA) tranches from later and more complex deals have avoided performing costly due diligence on the securities they bought. 相似文献

Bank capital buffer and portfolio risk: The influence of business cycle and revenue diversification 总被引:2,自引:0,他引:2
The relationship between macroeconomic developments and bank capital buffer and portfolio risk adjustments is relevant to assess the efficacy of newly created countercyclical buffer requirements. Using the U.S. bank holding company data over the period 1992:Q1–2011:Q3, we find a negative relationship between the business cycle and capital buffer. Our results offer some support for the Basel III agreements that countercyclical capital buffer in the banking sector is necessary to help the performance of the real economy during recessions. We find a robust evidence of inverse relationship between business cycle and bank default risk. Our analysis provides evidence of diversification benefits. The probability of insolvency risk decreases for diversified banks and banks with high revenue diversity achieve capital savings. 相似文献

This paper explores costs and proceeds from loan collateral in the credit market with ex-ante asymmetric information when collateral value and the probability of project success fluctuate. A borrower is willing to pledge collateral if (i) its future value is correlated with the probability of project success, or (ii) its value fluctuates strongly, or (iii) it is funded with loan capital. When one of the conditions is satisfied, in contrast to Bester (1985), a high-risk borrower may be more willing to pledge collateral than a low-risk borrower. The paper is related to topical subprime crises and real estate collateral. 相似文献

The barrier options theory of corporate security valuation is applied to the contingent claims of a regulated bank. The regulator/insurer of a bank owns a down-and-in call option on the bank assets which can be balanced against the expected coverage cost. Raising the regulatory barrier (critical asset level triggering bank closure) leads to a transfer of wealth from stockholders to the insurer and reduces stockholder incentives to increase asset risk. Empirical tests on a sample of 152 one-bank holding companies show that regulatory barriers are priced in the stock market and are inversely related to Tier 1 leverage ratios. 相似文献

This paper analyzes empirically what explains the low profitability of Chinese banks for the period 1997–2004. We find that better capitalized banks tend to be more profitable. The same is true for banks with a relatively larger share of deposits and for more X-efficient banks. In addition, a less concentrated banking system increases bank profitability, which basically reflects that the four state-owned commercial banks – China’s largest banks – have been the main drag for system’s profitability. We find the same negative influence for China’s development banks (so-called Policy Banks), which are fully state-owned. Instead, more market-oriented banks, such as joint-stock commercial banks, tend to be more profitable, which again points to the influence of government intervention in explaining bank performance in China. These findings should not come as a surprise for a banking system which has long been functioning as a mechanism for transferring huge savings to meet public policy goals. 相似文献

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. 相似文献

This paper presents two models in which the fluctuating value of loan collateral (real estate) generates the problem of moral hazard between a bank and a deposit insurance agent. The bank finances risky projects against collateral and relies on the rising collateral value. If the collateral value later appreciates, the bank enjoys handsome profits; otherwise, the bank fails. The findings are rather consistent with the characteristics of the topical subprime mortgage crisis. 相似文献

The theory of financial intermediation highlights various channels through which capital and liquidity are interrelated. Using a simultaneous equations framework, we investigate the relationship between bank regulatory capital and bank liquidity measured from on-balance sheet positions for European and US publicly traded commercial banks. Previous research studying the determinants of bank capital buffer has neglected the role of liquidity. On the whole, we find that banks decrease their regulatory capital ratios when they face higher illiquidity as defined in the Basel III accords or when they create more liquidity as measured by Berger and Bouwman (2009). However, considering other measures of illiquidity that focus more closely on core deposits in the United States, our results show that small banks strengthen their solvency standards when they are exposed to higher illiquidity. Our empirical investigation supports the need to implement minimum liquidity ratios concomitant to capital ratios, as stressed by the Basel Committee; however, our findings also shed light on the need to further clarify how to define and measure illiquidity and also on how to regulate large banking institutions, which behave differently than smaller ones. 相似文献

This paper studies loss given default using a large set of historical loan-level default and recovery data of high loan-to-value residential mortgages from several private mortgage insurance companies. We show that loss given default can largely be explained by various characteristics associated with the loan, the underlying property, and the default, foreclosure, and settlement process. We find that the current loan-to-value ratio is the single most important determinant. More importantly, mortgage loss severity in distressed housing markets is significantly higher than under normal housing market conditions. These findings have important policy implications for several key issues in Basel II implementation. 相似文献

In this paper, we develop and test a model of implicit recourse in asset-backed securitizations. Fraud losses on securitized assets are generally incurred by the bank and do not affect the performance of securitization trusts, while credit losses do affect the trust’s performance and are potentially borne by the owner of the securitized assets. Thus, the classification of losses as either fraud or credit losses provides a potential avenue of implicit recourse to manipulate the performance of securitization trusts. Using annual data from 2001 to 2006, we find that the performance of the credit card securitization portfolio is negatively related to fraud losses reported by the bank. We examine these results in light of the proposed Basel II capital rules and argue that a bank’s incentive to provide implicit recourse will increase under the anticipated regime. 相似文献

Capital management by mutual financial institutions (such as credit unions) provides a valuable testing ground for assessing the impact of capital regulation and theories of managerial behaviour in financial institutions. Limited access to external equity capital means that capital accumulation must be met primarily by reliance on retained earnings. To deal with shocks to the capital position and avoid breaching regulatory requirements, managers will aim to have a buffer of capital in excess of the regulatory minimum. Moreover, mutual governance arrangements and an absence of capital market discipline mean that managers have discretion to set target capital ratios which differ significantly from industry averages. This paper develops a formal model of capital management and risk management in mutual financial institutions such as credit unions which reflects these industry characteristics. The model is tested using data from larger credit unions in Australia, which have been subject to the Basel Accord Risk Weighted Capital Requirements since 1993. The data supports the hypothesis that credit unions manage their capital position by setting a short term target profit rate (return on assets) which is positively related to asset growth and which is aimed at gradually removing discrepancies between the actual and desired capital ratio. Desired capital ratios vary significantly across credit unions. There is little evidence of short run adjustments to the risk of the asset portfolio to achieve a desired capital position. 相似文献

Deteriorating public finances around the world raise doubts about countries’ abilities to bail out their largest banks. For an international sample of banks, this paper investigates the impact of bank size and government deficits on bank stock prices and CDS spreads. We find that a bank’s market-to-book value is negatively related to the size of its liabilities-to-GDP ratio, especially in countries running large public deficits. CDS spreads appear to decrease with stronger public finances. These results suggest that systemically important banks can increase their value by downsizing or splitting up, especially if they are located in countries with weak public finances. We document that banks’ average liabilities-to-GDP ratio reached a peak in 2007 before a significant drop in 2008, which could reflect these private incentives to downsize. 相似文献

This paper addresses two questions related to the ongoing consolidation of the US banking industry and its effect on small firm financing. First, are conventional measures of market structure (e.g. geographic market size and deposit concentration) related to bank competition for small firm financial business? Second, does an increase in bank competition produce an improvement in bank services irrespective of market structure? To answer these questions we use a survey of small firm owners that asks them to report on changes in bank competition for their business. Our findings show that reports of increased competition by small firm owners are negatively related to the level of and change in deposit concentration. In addition, we find a significant positive association between changes in bank competition reported by small firms and their reports of changes in banking outcomes (e.g. service quality) that is independent of deposit concentration, firm risk, and credit usage. 相似文献

Can pure play internet banking survive the credit crisis? 总被引:1,自引:0,他引:1
This paper positions the pure-play internet banking model (PPI) as a hybrid business model that combines features of both relationship and transaction banking. Although in terms of customer orientation PPI banks may partly resemble relationship banks, they lack their comparative advantage in generating borrower-specific information. Instead, the characteristic features of PPI banks are low costs and easy scalability. While the latter may enable PPI banks to quickly capture market share, it may also generate overexposure in risky markets. We present a case study on ING Direct, one of the leading global PPI banks and address the sustainability of the PPI business model by comparing the ING Direct foreign operations. The findings for ING Direct are validated using data for E-Trade Bank. We conclude that managing growth appears to be the prime challenge to PPI banks. 相似文献

This paper examines two forces that may soon increase competition in the U.S. secondary conforming mortgage market: (1) the Federal Home Loan Bank mortgage purchase programs, and (2) the adoption of revised risk-based capital requirements for large U.S. banks (Basel II). We argue that this competition is likely to reduce the growth and relative importance of Fannie Mae and Freddie Mac and hence reduce their charter values and effective capital. Such developments could, in turn, lead to more risky behaviors by these two companies. This last consequence warrants greater supervisory awareness and legal authorities. 相似文献

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. 相似文献
