Financial friction in an emerging economy

The objective of this study is to evaluate the role of the frictional domestic credit market in an emerging country by using a small-open-economy DSGE model with a banking sector. The calibration results show that the financial friction does not significantly influence the macroeconomic effects of the shocks to the domestic productivity, foreign interest rate and export demand. We also evaluate whether and how the trade and financial openness can influence the effects of the domestic financial shocks that in turn affect the supply of loans in the credit market. We show that greater trade and financial openness can reduce the macroeconomic impacts of the domestic financial distress. Under a more open international capital market, the capital outflow caused by the domestic financial shock does not lead to drastic exchange rate variation. This helps dampen the adverse effects of the financial distress on the economy.     

Does adding up of economic capital for market- and credit risk amount to conservative risk assessment?

There is a tradition in the banking industry of dividing risk into market risk and credit risk. Both categories are treated independently in the calculation of risk capital. But many financial positions depend simultaneously on both market risk and credit risk factors. In this case, an approximation of the portfolio value function separating value changes into a pure market risk plus pure credit risk component can result not only in an overestimation, but also in an underestimation of risk. We discuss this compounding effect in the context of foreign currency loans and argue that a separate calculation of economic capital for market risk and for credit risk may significantly underestimate true risk.     

An economic capital model integrating credit and interest rate risk in the banking book

Banks often measure credit and interest rate risk in the banking book separately and then add the risk measures to determine economic capital. This approach misses complex interactions between the two risk types. We develop a framework where these risks are analysed jointly. Since banking book positions are generally not marked to market, our model is based on book value accounting. Our simulations show that interactions matter, and that ignoring them leads to risk overstatement. The magnitude of the errors depends on the structure of the balance sheet and on the repricing characteristics of assets and liabilities.     

Capital shocks, bank asset allocation, and the revised Basel Accord

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.

Capital requirements and bank behavior in the UK: Are there lessons for international capital standards?

The financial crisis prompted widespread interest in developing a better understanding of how capital regulation drives bank behavior. This paper uses a unique, comprehensive database of regulatory capital requirements on all UK banks to examine their effects on capital, lending and balance sheet management behavior. We find that capital requirements that include firm-specific, time-varying add-ons set by supervisors affect banks’ desired capital ratios and that resulting adjustments to capital and lending depend on the gap between actual and target ratios. We use these results to measure the effects of a capital regime that includes features similar to those embedded in the UK framework. Our results suggest that countercyclical capital requirements may be less effective in slowing credit activity when banks can readily satisfy them with lower-quality (lower-costing) capital elements versus higher-quality common equity. Given the size of the UK banking sector and the global nature of many of the largest institutions in the UK banking sector, the results have implications for the ongoing debate surrounding the design and calibration of international capital standards.     

The effect of banking crisis on bank-dependent borrowers

We provide causal evidence that adverse capital shocks to banks affect their borrowers’ performance negatively. We use an exogenous shock to the U.S. banking system during the Russian crisis of Fall 1998 to separate the effect of borrowers’ demand of credit from the supply of credit by the banks. Firms that primarily relied on banks for capital suffered larger valuation losses during this period and subsequently experienced a higher decline in their capital expenditure and profitability as compared to firms that had access to the public-debt market. Consistent with an adverse shock to the supply of credit, crisis-affected banks decreased the quantity of their lending and increased loan interest rates in the post-crisis period significantly more than the unaffected banks. Our results suggest that the global integration of the financial sector can contribute to the propagation of financial shocks from one economy to another through the banking channel.

Corporate distress and lobbying: Evidence from the Stimulus Act

The literature on distressed firms has focused on these firms’ investment, capital structure, and labor decisions. This paper investigates a novel aspect of firm behavior in distress: how financial health affects a firm?s lobbying and, consequently, its relationship with the government. We exploit the shock to nonfinancial firms during the 2008 financial crisis and the availability of the stimulus package in the first quarter of 2009. We find that firms with weaker financial health, as measured by credit default swap spreads, lobbied more. We also show that the amount spent on lobbying was associated with a greater likelihood of receiving stimulus funds.     

Capital management in mutual financial institutions

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.     

Credit risk transfer and contagion

Some have argued that recent increases in credit risk transfer are desirable because they improve the diversification of risk. Others have suggested that they may be undesirable if they increase the risk of financial crises. Using a model with banking and insurance sectors, we show that credit risk transfer can be beneficial when banks face uniform demand for liquidity. However, when they face idiosyncratic liquidity risk and hedge this risk in an interbank market, credit risk transfer can be detrimental to welfare. It can lead to contagion between the two sectors and increase the risk of crises.     

A practical approach to validating a PD model

The capital adequacy framework Basel II aims to promote the adoption of stronger risk management practices by the banking industry. The implementation makes validation of credit risk models more important. Lenders therefore need a validation methodology to convince their supervisors that their credit scoring models are performing well. In this paper we take up the challenge to propose and implement a simple validation methodology that can be used by banks to validate their credit risk modelling exercise. We will contextualise the proposed methodology by applying it to a default model of mortgage loans of a commercial bank in the Netherlands.     

Does prudential regulation contribute to effective measurement and management of interest rate risk? Evidence from Italian banks

This paper contributes to prior literature and to the current debate concerning recent revisions of the regulatory approach to measuring bank exposure to interest rate risk in the banking book by focusing on assessment of the appropriate amount of capital banks should set aside against this specific risk. We first discuss how banks might develop internal measurement systems to model changes in interest rates and measure their exposure to interest rate risk that are more refined and effective than are regulatory methodologies. We then develop a backtesting framework to test the consistency of methodology results with actual bank risk exposure. Using a representative sample of Italian banks between 2006 and 2013, our empirical analysis supports the need to improve the standardized shock currently enforced by the Basel Committee on Banking Supervision. It also provides useful insights for properly measuring the amount of capital to cover interest rate risk that is sufficient to ensure both financial system functioning and banking stability.     

TARP announcement,bank health,and borrowers’ credit risk

Theory suggests that unhealthy banks exhibit more pronounced flight-to-quality behavior during financial crises and, hence, the infusion of capital through unhealthy banks is less effective in relieving the liquidity shocks of vulnerable borrowers. We test these predictions by investigating how the financial health of leading US banks influenced their borrowers’ credit risk surrounding the announcement of the Troubled Asset Relief Program (TARP). Changes in borrower credit risk, measured by credit default swap (CDS) spreads, should reflect the expected relief from liquidity shocks and other benefits of rescuing banks, such as maintaining the existing lending relationships. Consistent with the theory, prior to the TARP capital infusions, unhealthy banks’ borrowers with high leverage experienced a greater increase in their credit risk relative to similar healthy banks’ borrowers. Following the event, the CDS market anticipated less liquidity relief to these vulnerable unhealthy banks’ borrowers, but more liquidity relief to the vulnerable healthy banks’ borrowers.     

Credit supply and corporate innovation

We present evidence that banking development plays a key role in technological progress. We focus on manufacturing firms' innovative performance, measured by patent-based metrics, and employ exogenous variations in banking development arising from the staggered deregulation of banking activities across US states during the 1980s and 1990s. We find that interstate banking deregulation had significant beneficial effects on the quantity and quality of innovation activities, especially for firms highly dependent on external capital and located closer to entering banks. Furthermore, we find that these results are strongly driven by a greater ability of deregulated banks to geographically diversify credit risk.     

A compound option approach to model the interrelation between banking crises and country defaults: The case of Hungary 2008

We analyze the Hungarian financial crisis of 2008 in a stochastic framework that advances structural credit risk models for country defaults: by applying compound option theory we consider payments for bailing-out the banking sector together with debt service payments in a joint crisis model. We estimate the model parameters by applying the time series maximum-likelihood approach of Duan (1994) on yield spreads of Hungarian Bonds. We find that difficulties in acquiring funds for debt servicing in combination with high outstanding debt triggered the crisis, rather than problems in the domestic banking sector. The estimated crisis probabilities dramatically rise during 2008.     

Is sovereign risk related to the banking sector?

We examine whether the banking sector within a nation is related to sovereign risk. We hypothesize that more competitive and sophisticated financial systems are less prone to panics or bank runs, and consequently will be associated with superior sovereign credit ratings. Using Ordered Probit with Aggregate Time Effects methodology, our results show that banking sector characteristics such as concentration in the banking system, liquidity of bank assets, and size of financial system are significantly related to sovereign credit ratings. Since the use of these sovereign ratings is ubiquitous in international finance in varied applications such as determination of the cost of international borrowing by governments, international cost of capital for FDI, and others, the relationships identified in this paper have important public policy implications.     

Shadow Banks and Macroeconomic Instability

We develop a macroeconomic model in which commercial banks can offload risky loans to a “shadow” banking sector, and financial intermediaries trade in securitized assets. The model can account both for the business cycle comovement between output, traditional bank, and shadow bank credit, and for the behavior of macroeconomic variables in a liquidity crisis centered on shadow banks. We find that following a liquidity shock, stabilization policy aimed solely at the market in securitized assets is relatively ineffective.     

The impact of state ownership on performance differences in privately-owned versus state-owned banks: An international comparison

This paper examines how government ownership and government involvement in a country’s banking system affect bank performance from 1989 through 2004. Our study uncovers an interesting pattern of changing performance differences between state-owned and privately-owned banks around the Asian financial crisis. We find that state-owned banks operated less profitably, held less core capital, and had greater credit risk than privately-owned banks prior to 2001, and the performance differences are more significant in those countries with greater government involvement and political corruption in the banking system. In addition, from 1997 to 2000, the 4-year period after the beginning of the Asian financial crisis, the deterioration in the cash flow returns, core capital, and credit quality of state-owned banks was significantly greater than that of privately-owned banks, especially for the countries that were hardest hit by the Asian crisis. However, state-owned banks closed the gap with privately-owned banks on cash flow returns, core capital, and nonperforming loans in the post-crisis period of 2001–2004. Our findings can best be explained by Shleifer and Vishny’s [Shleifer, A., Vishny, R.W., 1997. A survey of corporate governance. J. Finance 52, 737–783] corporate governance theory on state ownership of firms and Kane’s [Kane, E.J., 2000. Capital movement, banking insolvency, and silent runs in the Asian financial crisis. Pacific-Basin Finance J. 8, 153–175] life-cycle model of a regulation-induced banking crisis.     

Economic value,competition and financial distress in the European banking system

In this paper we examine the impact of a large number of factors at the bank level (liquidity and credit risks, asset size, income diversification and market power), at the industry level (banking concentration) and macro-level (real GDP growth) on bank financial distress using an unbalanced panel of 308 European commercial banks between 1996 and 2009. The observations falling below a given threshold of the empirical distribution of the Shareholder Value Ratio proxy bank financial distress. We employ a panel probit regression and, given the presence of overlapping data giving rise to residual autocorrelation, we use the Bertschek and Lechner (1998) robust estimator of the covariance matrix of parameters. We show that credit risk, liquidity risk and bank market power are the most influential determinants of distressed Shareholder Value Ratio. Finally we evaluate the model out-sample forecasting performance over the 2008–2009 crisis period.
