In light of the current debate about the link between accounting and financial stability, we investigate the determinants of procyclical book leverage for U.S. commercial and savings banks. We find that total asset growth and GDP growth are both positively related to book leverage growth. Our evidence is not consistent with the notion that fair value accounting contributes to procyclical leverage or that historical cost accounting reduces procyclicality. Overall, the business model of banks is more important for procyclical leverage than accounting or regulatory risk weights.  相似文献

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value‐at‐Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR to measure risk and set these requirements. Assuming elliptically distributed asset returns, we show that portfolios on the mean‐SCVaR frontier generally lie away from the mean‐variance (M‐V) frontier. In a plausible numerical example, we find that such portfolios tend to have considerably higher ratios of risk (measured by, e.g., standard deviation) to minimum capital requirement than those of portfolios on the M‐V frontier. Also, we find that requirements based on SCVaR are smaller than those based on both VaR and SVaR but exceed those based on just VaR. Finally, we find that requirements based on SCVaR are less procyclical than those based on either VaR or both VaR and SVaR. Overall, our paper suggests that the use of SCVaR to measure risk and set requirements is not a panacea.  相似文献

I examine how financial innovation and Basel III capital requirements in Taiwan respond differently to banking crises and market competition. My panel data set comprises data from thirty-four banks for 2000-2012. I find a significant negative relationship between derivatives and the value of a bank and significant positive relationships among the capital adequacy ratio, bank-specific variables, and the value of a bank. Larger bank size and operational diversification tend to be positively associated with a bank's value, the holding of a relatively high amount of capital requirements, and nonperforming loans that are large. The latter result may simply reflect the scale of economy and improvement of efficiency in terms of financial innovation in the banking sector.  相似文献

Using a multicountry panel of banks, we study whether better capitalized banks experienced higher stock returns during the financial crisis. We differentiate among various types of capital ratios: the Basel risk‐adjusted ratio, the leverage ratio, the Tier 1 and Tier 2 ratios, and the tangible equity ratio. We find several results: (i) before the crisis, differences in capital did not have much impact on stock returns; (ii) during the crisis, a stronger capital position was associated with better stock market performance, most markedly for larger banks; (iii) the relationship between stock returns and capital is stronger when capital is measured by the leverage ratio rather than the risk‐adjusted capital ratio; (iv) higher quality forms of capital, such as Tier 1 capital and tangible common equity, were more relevant.  相似文献

We use a quasi‐experimental research design to examine the effect of model‐based capital regulation on the procyclicality of bank lending and firms' access to funds. In response to an exogenous shock to credit risk in the German economy, capital charges for loans under model‐based regulation increased by 0.5 percentage points. As a consequence, banks reduced the amount of these loans by 2.1 to 3.9 percentage points more than for loans under the traditional approach with fixed capital charges. We find an even stronger effect when we examine aggregate firm borrowing, suggesting that microprudential capital regulation can have sizeable real effects.  相似文献

This paper critiques the revised Basel II capital requirements for banks. To provide a framework for analysis, the XYZ theory of regulatory capital is formulated. Independent of the XYZ theory, we argue that the revised Basel II capital rule for credit risk is not a good approximation to the ideal rule. Based on this, and using the XYZ theory, we argue that: (1) the revised Basel II rules should not replace the existing approaches for determining minimal capital standards, but should be used in conjunction with them, and (2) that calibrating the capital rules to maintain aggregate market capital is a prudent procedure.  相似文献

We analyze the relationship between bank size and risk-taking under the Basel II Capital Accord. Using a model with imperfect competition and moral hazard, we show that the introduction of an internal ratings based (IRB) approach improves upon flat capital requirements if the approach is applied uniformly across banks and if the costs of implementation are not too high. However, the banks’ right to choose between the standardized and the IRB approaches under Basel II gives larger banks a competitive advantage and, due to fiercer competition, pushes smaller banks to take higher risks. This may even lead to higher aggregate risk-taking.  相似文献

In contrast to the 1988 Basel Accord (Basel I), the revised risk-based capital standards (Basel II) propose regulatory capital requirements based on credit ratings. This paper develops a theoretical model to analyze how banks will adjust their low and high credit risk commercial loans under the proposed newer standard. Capital-constrained banks respond to an adverse capital shock by reducing high credit risk loans, while under certain circumstances, low credit risk loans may actually increase. When compared to Basel I, it is shown that high-risk loans are reduced more under Basel II, but whether a bank reduces total lending more under Basel I or under the revised standards depends on a complex interaction of factors.  相似文献

Using data from three countries (US, Italy and Australia) and surveying related studies from several other countries in Europe, we investigate the effects of the New Basel Capital Accord on bank capital requirements for small and medium sized enterprises (SMEs). We find that, for all the countries, banks will have significant benefits, in terms of lower capital requirements, when considering small and medium sized firms as retail customers. But they will be obliged to use the Advanced IRB approach and to manage them on a pooled basis. For SMEs as corporate, however, capital requirements will be slightly greater than under the existing Basel I Capital Accord. We believe that most eligible banks will use a blended approach (considering some SMEs as retail and some as corporate). Through a breakeven analysis, we find that for all of our countries, banking organizations will be obliged to classify as retail at least 20% of their SME portfolio in order to maintain the current capital requirement (8%).

This paper identifies a monetary policy channel through the risk pricing of bank debt in the market for jumbo certificates of deposit (jumbo CDs). Adverse policy shocks increase debt holder perceptions of bank default, increasing the risk premia for some banks, thereby decreasing their external funding of loans. The results show that contractionary policy increases the sensitivity of jumbo‐CD spreads to leverage and asset risk for small banks, and to leverage for large banks. The results also show a distributional and aggregate effect on banking system jumbo CDs and total loans, producing a risk‐pricing (or market discipline) channel. This channel has implications for monetary and regulatory policies, and financial stability.  相似文献

This paper explores the consequences of the collapse of the private‐label residential mortgage‐backed securities market in 2007 on banks’ originations of jumbo mortgages. We show that jumbo lending declined by more at banks that were more dependent on this market and were less well capitalized. In contrast, banks that had little dependence on this market and were well capitalized increased jumbo originations. These findings highlight how dependence on the secondary market may cause amplification of financial shocks, and the potential value of capital requirements that are higher during periods of economic growth in mitigating the amplification effects.  相似文献

New bank equity must come from somewhere. In general equilibrium, raising bank capital requirements means either that banks produce less short‐term debt (as debt holders must become shareholders), or short‐term debt is not reduced and the banking system acquires nonbank equity (as the shareholders in nonbanks become shareholders in banks). The welfare effects involve a trade‐off because bank debt is special as it is used for transactions purposes, but more bank capital can reduce the chance of bank failure (producing welfare losses).  相似文献

In attempting to promote international financial stability, the Basel Committee on Banking Supervision (2006) provided a framework that sought to control the amount of tail risk that large banks around the world would take in their trading books relative to their corresponding minimum capital requirements. However, many of these banks suffered significant trading losses during the recent financial crisis. Our paper examines whether the Basel framework allowed banks to take substantive tail risk in their trading books without a capital requirement penalty. We find that it allowed banks to do so and that its minimum capital requirements can be notably procyclical. Hence, focusing on the way the Basel framework sought to control the amount of tail risk in trading books relative to their corresponding minimum capital requirements, our paper supports the view that it was not properly designed to promote financial stability. We also discuss alternative regulatory frameworks that would potentially be more effective than the Basel framework in preventing banks from taking substantive tail risk in their trading books without a capital requirement penalty.  相似文献

We investigate the liquidity management of 62 Dutch banks between January 2004 and March 2010, when these banks were subject to a liquidity regulation that is very similar to Basel III’s Liquidity Coverage Ratio (LCR). We find that most banks hold more liquid assets against their stock of liquid liabilities, such as demand deposits, than strictly required under the regulation. More solvent banks hold fewer liquid assets against their stock of liquid liabilities, suggesting an interaction between capital and liquidity buffers. However, this interaction turns out to be weaker during a crisis. Although not required, some banks consider cash flows scheduled beyond 1 month ahead when setting liquidity asset holdings, but they seldom look further ahead than 1 year.  相似文献

This paper explores how the legal environment affects bank behavior in 20 transition economies. Based on a newly constructed data set we find that banks’ loan portfolio composition depends on the legal environment. If banks operate in a well‐functioning legal environment they lend relatively more to SMEs and provide more mortgages. On the other hand, banks lend more to large enterprises and to the government if the legal system is unsound. As a transmission channel we identify the banks’ willingness to accept collateral which depends on the bankers’ perceptions of the prevailing laws regarding collateral.  相似文献

This paper combines the static effect of ownership and the dynamic effect of privatization on bank performance in China over 1995–2010, reporting a significantly higher performance by private intermediaries – joint stock commercial banks and city commercial banks – relative to state-owned commercial banks. However, publicly traded banks, subject to multiple monitoring and vetting in capital markets, perform better regardless of ownership status. The privatization of banks has improved performance with respect to revenue inflow and efficiency gains in the short- or long-run (initial public offerings). The positive long-run effect is more relevant and significant for banking institutions with minority foreign ownership. Moreover, this paper innovatively estimates interest income efficiency and non-interest income efficiency at the same time. The results suggest that Chinese banks are much more efficient in generating interest income than raising non-interest revenue, although the latter aspect has improved significantly during the sample period.  相似文献

Geographic Diversification, Bank Holding Company Value, and Risk   总被引:3,自引:0,他引:3  
We assess the association between geographic diversification and bank holding company (BHC) value and risk, controlling for the distance between the headquarters and branches. The distance-adjusted deposit dispersion index used as a measure of geographic diversification accounts for the number of locations where a BHC operates, the level of activity in each location, and the distance between a BHC and its branches. We find that geographic diversification is associated with BHC value enhancement and risk reduction, increased distance between a BHC and its branches is associated with firm value reduction and risk increase, and geographic diversification across more remote areas is associated with greater value enhancement but smaller risk reduction.  相似文献
