Double leverage cycle,interest rate,and financial crisis

We view mortgage as a risky derivative of its underlying house collateral and combine no-arbitrage valuation with equilibrium valuation approaches to develop a dynamic model of leverage cycle and interest rate. This model provides a unified explanation to pro-cyclical optimism, asset prices, and leverage, and counter-cyclical volatility and interest rate. In addition, the model shows that tightening funding margin in the mortgage securities market dampens optimism, asset prices, and leverage, whereas it raises volatility and interest rate in the housing market. A double leverage cycle leads to more volatile markets and a severe leverage cycle, thus resulting in worse financial crises.     

The impact of the sovereign debt crisis on the activity of Italian banks

We examine the implications of the sovereign debt tensions on the Italian credit market by estimating the effect of the 10-year BTP-Bund spread on a wide array of bank interest rates, categories of loans and income statement variables. We exploit the heterogeneity between large and small intermediaries to assess to what extent the transmission of sovereign risk differed in relation with different banks’ balance-sheet characteristics and business strategies. Regarding the cost of funding, we find that changes in the BTP-Bund spread have a sizeable effect on the interest rates on term deposits and newly issued bonds but virtually no effect on overnight deposits. Furthermore, the sovereign spread significantly affects the cost of credit for firms and households and exerts a negative effect on loan growth. All these results are magnified when considering alone the five largest banks, which are typically less capitalized, have a larger funding gap and incidence of bad loans and rely more on non-traditional banking activities. Sovereign tensions also affect the main items of banks’ income statement.     

The interest rate pass-through in the Euro area during the global financial crisis

This paper uses panel vector autoregressive (VAR) models for euro area member countries to explore the widening of retail bank interest rate spreads that emerged in the course of the global financial crisis. We find that the interest rate pass-through was generally complete on impact before the outbreak of the financial crisis, but became significantly distorted in the period thereafter, which hampered the effectiveness of monetary policy. Empirical evidence suggests that the decrease in the interest rate pass-through can be related to a change in the structural parameters characterizing the economies and a substantial increase in the average size of structural shocks. DSGE model simulations show that an increase in the frictions that banks are subject to can explain the decrease in the retail bank interest rate pass-through.

Credit distortion and financial crisis

A simple and consistent theory based on credit distortion is developed to understand the origin of financial crises in the emerging markets. We prove that without the guarantee of various government agencies on the credit risk of foreign loans, the interest rate on foreign loans would be the same as the domestic loans, which would eliminate the incentive to borrow foreign loans on a great scale. We demonstrate that the common phenomena preluding the crisis, such as heavy foreign borrowing and overinvestment in real estate, are rational choices when a particular currency is overvalued and cheap credit is available.     

The dispositif of risk management: Reconstructing risk management after the financial crisis

Despite its dubious role during the global financial crisis of 2008, risk management has continued its expansion. This paper addresses the question why risk management, in the face of its evident failure to manage risks during the crisis, has retained its importance even today. We build on the existing critical literature on risk management (Power, 2007) and advance it by introducing a more rigorous consideration of power. We refer to the notion of the “permanent state of exception” as conceptualized by the Italian social theorist Giorgio Agamben, 1998, Agamben, 2005 in order to argue that risk is a powerful social category as it reflects a potential exception, challenging norms as well as normalizing forms of control. We conclude that a dispositif of risk management, an assemblage of institutions, regulations and models, lies at the heart of risk management. This dispositif provides elites engaged in risk management with an argument that allows them – in exceptional situations – to take extraordinary measures which cannot be rescinded after the initial state of exception has ended. The logic of the state of exception can be used as a discursive resource and adds to, but also gradually replaces, other forms of management control. Our study contributes to management control theory by focusing on post-disciplinary forms of control and provides a novel focus on how elites use management control systems for their own interests.     

Deposit interest rates, asset risk and bank failure in Croatia

Financial deregulation, while beneficial in the long-term, seems to be linked to instability. Intense competition for deposits appears to be an ingredient in instability. We examine the aftermath of deregulation in Croatia, which included rapid growth of both deposits and deposit interest rates, followed by numerous bank failures.

Using panel regression techniques, we find evidence of “market-stealing” via high deposit interest rates. We connect high deposit interest rates to bank failure using logit models. High deposit interest rates were a reliable signal of risk-taking. When supervisory capabilities and powers are weak, deposit interest rate regulation may be worth considering.     

Bank funding structures and risk: Evidence from the global financial crisis

This paper analyzes the evolution of bank funding structures in the run up to the global financial crisis and studies the implications for financial stability, exploiting a bank-level dataset that covers about 11,000 banks in the U.S. and Europe during 2001–09. The results show that banks with weaker structural liquidity and higher leverage in the pre-crisis period were more likely to fail afterward. The likelihood of bank failure also increases with pre-crisis bank risk-taking. In the cross-section, the smaller domestically-oriented banks were relatively more vulnerable to liquidity risk, while the large cross-border (Global) banks were more vulnerable to solvency risk due to excessive leverage. In fact, a 3.5 percentage point increase in the pre-crisis capital buffers of Global banks would have caused a 48 percentage point in their probability of failure during the crisis. The results support the proposed Basel III regulations on structural liquidity and leverage, but suggest that emphasis should be placed on the latter, particularly for the systemically-important institutions. Macroeconomic and monetary conditions are also shown to be related with the likelihood of bank failure, providing a case for the introduction of a macro-prudential approach to banking regulation.     

The role of on- and off-balance-sheet leverage of banks in the late 2000s crisis

Extensive regulatory changes and technological advances have transformed banking systems to a great extent. Banks have reacted to the challenges posed by the new operating environment by creating new products and expanding their activities to some uncharted business areas. In this paper, we study how modern banking which gave birth to the off-balance-sheet leverage activities affected the risk profile of U.S. banks as well as the level of systemic risk before and after the onset of the late 2000s financial crisis. Towards this, we separate on- from off-balance-sheet leverage and capture the latter with different, yet complementary, measures which do not exist in the current literature. Special attention is paid on the deleveraging process that occurred in the banking market after the crisis erupted, which is an additional innovative feature of this study. Our findings reveal that leverage, both explicit and hidden off-the-balance-sheet, increases the individual risk of banking firms making them vulnerable to financial shocks. Reverse leverage, on the other hand, is beneficial for individual banks’ health, but is found to be harmful for financial stability. We also demonstrate that the banks which concentrate on traditional lines of business typically carry less risk compared to those involved with modern financial instruments.     

A risk assessment model for banks

Summary. This paper proposes a model to assess risk for banks. Its main innovation is to incorporate endogenous interaction among banks, where the actual risk an individual bank bears also depends on its interaction with other banks and investors. We develop a two-period general equilibrium model with three active heterogeneous banks, incomplete markets, and endogenous default. The model is calibrated against UK banking data and therefore can be implemented as a risk assessment tool for regulators and central banks. We address the impact of monetary and regulatory policy, credit and capital shocks in the real and financial sectors.We are grateful to Lea Zicchino, an anonymous referee, seminar participants at the Bank of England, and the third Conference in Research in Economic Theory and Econometrics, Syros, for helpful comments.

Market-specific and currency-specific risk during the global financial crisis: Evidence from the interbank markets in Tokyo and London

This paper investigates how international money markets reflected credit and liquidity risk during the global financial crisis. After matching the currency denomination, we examine how the Tokyo Interbank Offered Rate (TIBOR) was synchronized with the London Interbank Offered Rate (LIBOR). We find remarkably asymmetric responses in market-specific and currency-specific risk during the crisis. The regression results suggest that market-specific credit risk increased the difference across markets, whereas liquidity risk caused the difference across currency denominations. They also support the view that liquidity shortage of the US dollar occurred in international money markets during the crisis. Coordinated central bank liquidity provisions were useful in reducing the liquidity shortage of the US dollar, but their effectiveness was asymmetric across markets.     

Understanding and managing interest rate risk at banks

Banks in many countries hold significant quantity of bonds issued by their sovereign. This nexus of bank balance sheets with the sovereign debt can amplify in a two-way loop the effect of a rise in sovereign debt yields on banks and vice-versa. The rise in sovereign debt yields tends to be episodic, exhibiting conditional volatility, and banks need to manage this risk proactively to dampen the two-way loop. Lessons are drawn from this perspective for understanding and managing of interest rate (or ‘duration’) risk at Indian banks from their holdings of government securities. Moral hazard implications of regulatory forbearance policies when the two-way loop materializes are also discussed.     

The impact of monetary policy announcements on the stock price of large European banks during the financial crisis

Since 2007, the European Central Bank responded decisively to the challenges posed by the global financial crisis, reducing key policy interest rates to unprecedented low levels and intervening with non-standard policy measures (i.e., monetary easing and liquidity provision). This paper aims to assess the impact of ECB monetary policy announcements on the stock price of large European banks. As a first step, an event study is conducted in order to measure cumulated abnormal returns (CARs) around the announcements over June 2007–June 2013; the second step is a regression analysis aimed at identifying the determinants of CARs. Results show that banks were more sensitive to non-conventional measures than to interest rate decisions, and that the same type of intervention may have a different impact depending on the stage of the crisis. In addition, banks with weaker balance sheets and operating with high-risk were more sensitive to monetary policy interventions.     

Financial reporting of European banks during the GFC: a pitch

This short paper applies the pitch template developed by Faff (2015a), for a proposed accounting research project on financial reporting of European banks and the global financial crisis. I begin by giving a brief background to writing the pitch. I then give a brief commentary on my pitch, followed by a few key personal reflections on the pitch exercise itself.     

International diversification and risk of multinational banks: Evidence from the pre-crisis period

The recent financial crisis has clearly shown that the relationship between bank internationalization and risk is complex. Multinational banks can benefit from portfolio diversification, reducing their overall riskiness, but this effect can be offset by incentives going in the opposite direction, leading them to take on excessive risks. Since both effects are grounded on solid theoretical arguments, the answer of what is the actual relationship between bank internationalization and risk is left to the empirical analysis. In this paper, we study such relationship in the period leading to the financial crisis of 2007–2008. For a sample of 384 listed banks from 56 countries, we calculate two measures of risk for the period from 2001 to 2007 – the expected default frequency (EDF), a market-based and forward-looking indicator, and the Z-score, a balance-sheet-based and backward-looking measure – and relate them to the degree of banks’ internationalization. We find robust evidence that international diversification increases bank risk.     

The impact of enterprise risk management on the marginal cost of reducing risk: Evidence from the insurance industry

We test the hypothesis that practicing enterprise risk management (ERM) reduces firms’ cost of reducing risk. Adoption of ERM represents a radical paradigm shift from the traditional method of managing risks individually to managing risks collectively allowing ERM-adopting firms to better recognize natural hedges, prioritize hedging activities towards the risks that contribute most to the total risk of the firm, and optimize the evaluation and selection of available hedging instruments. We hypothesize that these advantages allow ERM-adopting firms to produce greater risk reduction per dollar spent. Our hypothesis further predicts that, after implementing ERM, firms experience profit maximizing incentives to lower risk. Consistent with this hypothesis, we find that firms adopting ERM experience a reduction in stock return volatility. We also find that the reduction in return volatility for ERM-adopting firms becomes stronger over time. Further, we find that operating profits per unit of risk (ROA/return volatility) increase post ERM adoption.     

The Basel Committee proposals for a new capital accord: implications for Italian banks

Following a few general considerations on the recently proposed revision of the Basel Agreement on capital adequacy, this paper focuses on the first pillar of the Basel Committee proposals, the handling of capital requirements for credit risk in the banking book. The Basel Committee envisages an approach alternatively based on external ratings or on internal rating systems for the determination of the minimum capital requirement related to bank loan portfolios. This approach supports a system of capital requirements that is more sensitive to credit risk. On the basis of specific assumptions, these requirements provide a measure of the value at risk (VaR) produced by models used by major international banks. We first address the impact of the standardised and (internal ratings-based) IRB foundation approach using general data on Italian banks loans' portfolios default rates. We then simulate the impact of the proposed new rules on the corporate loan portfolios of Italian banks, using the unique data set of mortality rates recently published by the Bank of Italy. Three main conclusions emerge from the analysis: (i) the standardised approach implicitly penalizes Italian banks in their interbank funding as their rating is generally below AA/Aa, (ii) the average default rate experienced by Italian banks is higher than the one implied in the benchmark risk weight (BRW) proposed by the Basel Committee for the IRB foundation approach, thereby potentially leading to an increase in the regulatory risk weights, and (iii) the risk-weight is based on an average asset correlation that is significantly higher than the one historically recorded within the Italian banks' corporate borrowers. These findings support the need for a significant revision of the basic inputs and assumptions of the Basel proposals. Finally, in relation to the conditions that allow the capital market to effectively discipline banks, we comment on the proposals advanced in relation to the third pillar of the new capital adequacy scheme.     

Market response to syndicated loan announcements from high-profile failed and acquiring banks during the global financial crisis

Previous studies that have examined the impact of the 2008 financial crisis on syndicated loans have ignored potential differences between lending banks by explicitly or implicitly aggregating all lenders together and focusing on borrower characteristics. One must jointly consider both borrower and lender to fully understand the complex role of the syndicate during this period. We consider the identity of the lender, with a focus on five major US banks that failed and their five corresponding acquirers. Our results highlight the distinct roles of investment and commercial banks and facilitate an understanding of relationship and transactional-based lending.     

Individual financial risk tolerance and the global financial crisis

We investigate individual investors’ tolerance towards financial risk by focusing on changes associated with the global financial crisis (GFC) of 2007–2009. Financial risk tolerance (FRT) is analysed longitudinally controlling for demographic, socio‐economic and regional variations. In absolute terms, the change in FRT is small and contrasts with a popular view that risk tolerance is an elastic psychological state overly influenced by the pervading market conditions. Even in the presence of significant financial events, FRT tends to be a reasonably stable attribute in the shorter term but possibly influenced and reshaped by events more gradually over time.     

The real effects of financial constraints: Evidence from a financial crisis

We survey 1,050 Chief Financial Officers (CFOs) in the U.S., Europe, and Asia to directly assess whether their firms are credit constrained during the global financial crisis of 2008. We study whether corporate spending plans differ conditional on this survey-based measure of financial constraint. Our evidence indicates that constrained firms planned deeper cuts in tech spending, employment, and capital spending. Constrained firms also burned through more cash, drew more heavily on lines of credit for fear banks would restrict access in the future, and sold more assets to fund their operations. We also find that the inability to borrow externally caused many firms to bypass attractive investment opportunities, with 86% of constrained U.S. CFOs saying their investment in attractive projects was restricted during the credit crisis of 2008. More than half of the respondents said they canceled or postponed their planned investments. Our results also hold in Europe and Asia, and in many cases are stronger in those economies. Our analysis adds to the portfolio of approaches and knowledge about the impact of credit constraints on real firm behavior.
