Theories of bank behavior under capital regulation   总被引:3,自引:1,他引:3  
This paper reviews academic studies of bank capital regulation in an effort to evaluate the intellectual foundation for the imposition of the Basel I and Basel II systems of risk-based capital requirements. The theoretical literature yields general agreement about the immediate effects of capital requirements on bank lending and loan rates and the longer-term impacts on bank ratios of equity to total or risk-adjusted assets. This literature produces highly mixed predictions, however, regarding the effects of capital regulation on asset risk and overall safety and soundness for the banking system as a whole. Thus, the intellectual foundation for the present capital-regulation regime is not particularly strong. The mixed conclusions in the academic literature on banking certainly do not provide unqualified support for moving to an even more stringent and costly system of capital requirements. These widely ambiguous results do suggest, however, that assessing the implications of capital regulation for balance-sheet risk and monitoring effort in diverse banking systems is an important agenda for future theoretical research in the banking area.  相似文献

We study the impact of higher bank capital requirements on corporate lending spreads using granular bank- and loan-level data. Our empirical strategy employs the heterogeneity in capital requirements across banks and time of implementation in Switzerland. We find that changes in the capital deviation from the regulatory minimum affect lending spreads asymmetrically. In response to a reduction in the capital deviation, banks with deficits with respect to their risk-weighted capital requirement raise spreads relative to banks with surpluses and de-leverage. Banks respond to higher requirements by raising spreads and, for deficit banks, by cutting lending.  相似文献

This paper analyses the impact of credit information sharing on financial stability, drawing special attention to its interactions with credit booms. A probit estimation of financial vulnerability episodes—identified by jumps in the ratio of non-performing loans to total loans—is run for a sample of 159 countries divided into two sub-samples according to their level of development: 80 advanced or emerging economies and 79 less developed countries. The results show that: i) credit information sharing reduces financial fragility for both groups of countries; ii) for less developed countries, the main effect is the direct effect (reduction of NPL ratio once credit boom is controlled), suggesting a portfolio quality effect; iii) credit information sharing also mitigates the detrimental impact of a credit boom on financial fragility but this result holds only for advanced and emerging countries and for household credit booms; and iv) the depth of information sharing has a negative impact on the likelihood of credit booms (but not the coverage of IS).  相似文献

We develop a theoretical model of mortgage loss rates that evaluates their main underlying risk factors. Following the model, loss rates are positively influenced by the house price level, the loan-to-value of mortgages, interest rates, and the unemployment rate. They are negatively influenced by the growth of house prices and the income level. The calibration of the model for the US and Switzerland demonstrates that it is able to describe the overall development of actual mortgage loss rates. In addition, we show potential applications of the model for different macroprudential instruments: stress tests, countercyclical buffer, and setting risk weights for mortgages with different loan-to-value and loan-to-income ratios.  相似文献

In January 2006, federal regulators issued guidance requiring banks with specific high concentrations of commercial real estate (CRE) loans to tighten managerial controls. This paper shows that banks with concentrations in excess of the thresholds set in the guidance subsequently experienced slower growth in their CRE portfolios than can be explained by changes in bank or economic conditions. Moreover, banks above the CRE thresholds tended to have slower commercial and industrial loan growth but faster household loan growth following issuance of the guidance. The results highlight the potentially broad influence that portfolio-based macroprudential regulation might have on bank behavior.  相似文献

I discuss changes to bank supervision and regulation since the financial crisis. Microprudential supervision promotes the safety and soundness of individual institutions, while macroprudential supervision focuses on emerging risks to financial system stability. I highlight tools for implementing this macroprudential approach to promoting financial stability, and discuss the interactions and proper relationship between monetary policy and financial stability. While macroprudential tools should be the first line of defense against emerging financial imbalances, in cases where those tools proved to be inadequate to limit risks to financial stability, monetary policy should be considered as a possible defense.  相似文献

The financial crisis showed, once again, that neglecting real estate booms can have disastrous consequences. In this paper, we spell out the circumstances under which a more active policy agenda on this front would be justified. Then, we offer insights on the pros and cons as well as implementation challenges of various policy tools that can be used to contain the damage to the financial system and the economy from real estate boom–bust episodes. These insights derive from econometric analysis, when possible, and case studies of country experiences. Broadly, booms financed through credit and involving leverage are more likely to warrant a policy response. In that context, macroprudential measures can be targeted more precisely to specific sources of risk, but they may prove ineffective because of circumvention. In that case, monetary policy may have to be used to lean against the wind.  相似文献

Several recent studies have recommended greater reliance on subordinated debt as a tool to discipline bank risk taking. Some of these proposals recommend using sub-debt yield spreads as triggers for supervisory discipline under prompt corrective action (PCA). Currently such action is prompted by capital adequacy measures. This paper provides the first empirical analysis of the relative accuracy of various capital ratios and sub-debt spreads in predicting bank condition: measured as subsequent CAMEL or BOPEC ratings. The results suggest that some of the capital ratios, including the summary measure used to trigger PCA, have almost no predictive power. Sub-debt yield spreads performed slightly better than the best capital measure, the Tier-1 leverage ratio, albeit the difference is not significant. The performance of sub-debt yields satisfies an important pre-requisite for using sub-debt as a PCA trigger. However, the prediction errors are relatively high and further work to refine the measures would be desirable.  相似文献

This paper analyzes the effect of the business cycle on the regulatory capital buffers of German local banks in the period 1993–2004. The capital buffers are found to fluctuate countercyclically over the business cycle. The evidence supports that low-capitalized banks do not catch up with their well-capitalized peers over the observation period and they do not decrease risk-weighted assets during a recession. This finding suggests that their low capitalization does not force them to retreat from lending.  相似文献

ABSTRACT

We show that internal funds play a particular role in the regulation of bank capital, which has not received much attention, yet. A bank's decision on loan supply and capital structure determines its immediate bankruptcy risk as well as the future availability of internal funds. These internal funds in turn determine a bank's future costs of external finance and its future vulnerability to bankruptcy risks. Using a partial equilibrium model, we study how internal funds affect these intra- and intertemporal links. Moreover, our positive analysis identifies the effects of risk-weighted capital-to-asset ratios, liquidity coverage ratios and regulatory margin calls on the dynamics of internal funds and thus loan supply and bank stability. Only regulatory margin calls or large liquidity coverage ratios achieve bank stability for all risk levels, but for large risks a bank will stop credit intermediation.  相似文献

Analysing the database made available by the European Central Bank and by the European Banking Authority, we evaluate the Comprehensive Assessment (CA) (Asset Quality Review and Stress Test (ST)) of banks carried out in 2014. In a nutshell, the main results are: (i) risk-adjusted capital ratios are negatively related to the Asset Quality Review shortfall, but not to the ST shortfall, whereas the leverage ratio plays a significant role in both cases; (ii) the CA predominantly concentrated on traditional credit activity rather than on banks’ financial assets and (iii) the CA seems to be characterized by double standards. The Asset Quality Review was severe with banks operating in non-core countries, while medium-sized banks were either riskier or were treated severely in both exercises. The analysis leads to a puzzle: comparatively, the assessment per se led to significant adjustments for solid banks and large shortfalls for weak banks. The puzzle can be resolved by referring to the legacy of the country’s former supervisory activity and to the low level of capitalization of weak banks mostly in peripheral countries.

During the last twenty years an increasing number of proposals to improve bank market discipline through the introduction of a mandatory subordinated debt policy (MSDP) have been presented and critically discussed by academic economists and bank regulators. While theoretical issues are key in this debate, a proper understanding of the market for banks' subordinated notes and debentures (SND) and the main features of securities is also considered relevant for the potential introduction, design and goals setting of such a policy. This paper builds on information concerning issuers, investors, markets, pricing and the technical features of securities to critically discuss these aspects. Data on over 1800 European banks SND issues completed during the 1988–2000:Q1 period together with information on primary and secondary market functioning are presented.  相似文献

Credit Card Securitization and Regulatory Arbitrage   总被引:1,自引:1,他引:1  
This paper explores the motivations and desirability of off-balance sheet financing of credit card receivables by banks. We explore three related issues: the degree to which securitizations result in the transfer of risk out of the originating bank, the extent to which securitization permits banks to economize on capital by avoiding regulatory minimum capital requirements, and whether banks' avoidance of minimum capital regulation through securitization with implicit recourse has been undesirable from a regulatory standpoint. We show that regulatory capital arbitrage is an important consequence of securitization. The avoidance of capital requirements could be motivated either by efficient contracting or by safety net abuse. We find that securitizing banks set their capital relative to managed assets according to market perceptions of their risk, and seem not to be motivated by maximizing implicit subsidies relating to the government safety net when managing their risk. This evidence is more consistent with the efficient contracting view of securitization with implicit recourse than with the safety net abuse view.  相似文献

This paper examines the impact of bank capital ratios on bank lending by comparing differences in loan growth to differences in capital ratios at sets of banks that are matched based on geographic area as well as size and various business characteristics. We argue that such comparisons are most effective at controlling for local loan demand and other environmental factors. For comparison we also control for local factors using MSA fixed effects. We find, based on data from 2001 to 2011, that the relationship between capital ratios and bank lending was significant during and shortly following the recent financial crisis but not at other times. We find that the relationship between capital ratios and loan growth is stronger for banks where loans are contracting than where loans are expanding. We also show that the elasticity of bank lending with respect to capital ratios is higher when capital ratios are relatively low, suggesting that the effect of capital ratio on bank lending is nonlinear. In addition, we present findings on the relationship between bank capital and lending by bank size and loan type.  相似文献

European banks became a source of risk to global financial markets during the financial crisis and attention to the European banking sector increased during the sovereign debt crisis. To measure the systemic risk of European banks, we calculate a distress insurance premium (DIP), which integrates the characteristics of bank size, probability of default, and correlation. Based on this measure, the systemic risk of European banks reached its height in late 2011 around €500 billion. We find that this was largely due to sovereign default risk. The DIP methodology is also used to measure the systemic contribution of individual banks. This approach identifies the large systemically important European banks, but Italian and Spanish banks as a group notably increased in systemic importance during the sample period. Bank-specific fundamentals like capital-asset ratios predict the one-year-ahead systemic risk contributions.  相似文献

This paper argues that counter-cyclical liquidity hoarding by financial intermediaries may strongly amplify business cycles. It develops a dynamic stochastic general equilibrium model in which banks operate subject to agency problems and funding liquidity risk in their intermediation activity. Importantly, the amount of liquidity reserves held in the financial sector is determined endogenously: Balance sheet constraints force banks to trade off insurance against funding outflows with loan scale. A financial crisis, simulated as an abrupt decline in the collateral value of bank assets, triggers a flight to liquidity, which strongly amplifies the initial shock and induces credit crunch dynamics sharing key features with the Great Recession. The paper thus develops a new balance sheet channel of shock transmission that works through the composition of banks’ asset portfolios.  相似文献

Identifying macroeconomic effects of credit shocks is difficult because many of the same factors that influence the supply of loans also affect the demand for credit. Using bank-level responses to the Federal Reserve's Loan Officer Opinion Survey, we construct a new credit supply indicator: changes in lending standards, adjusted for the macroeconomic and bank-specific factors that also affect loan demand. Tightening shocks to this credit supply indicator lead to a substantial decline in output and the capacity of businesses and households to borrow from banks, as well as to a widening of credit spreads and an easing of monetary policy.  相似文献

U.S. banking regulators have proposed a bifurcated system of capital regulation where the largest, internationally active banking organizations would be subject to significantly more risk sensitive regulatory capital requirements than are currently in place, while most others would remain subject to the current rules. The proposed new capital regime has the potential to affect the competitive landscape among banking institutions, particularly in the area of residential mortgage lending. We analyze the potential competitive effects of the proposed, bifurcated regulatory capital system on competition in the residential mortgage market from the perspective of the theory of regulatory capital arbitrage. We then apply the theory and available evidence to perform some benchmark calculations that suggest a significant, potential shift of market share and income to the largest banking institutions in the mortgage market.
