Quantifying structural subsidy values for systemically important financial institutions

Claimants to Systemically Important Financial Institutions (SIFIs) would receive transfers when governments are forced into bailouts. Ex ante, this bailout expectation lowers SIFIs’ daily funding costs. The funding cost advantage reflects both the structural level of the government support and the time-varying market valuation for such a support. Based on a large worldwide sample of banks, we estimate the value of the structural subsidy, by exploiting expectations of state support embedded in credit ratings and by applying the long-run average value of the rating bonus. The value of the structural subsidy was already sizable, 60 basis points (bp), as of the end-2007, before the crisis. It increased to 80 bp by the end-2009.     

A framework for assessing the systemic risk of major financial institutions

In this paper we propose a framework for measuring and stress testing the systemic risk of a group of major financial institutions. The systemic risk is measured by the price of insurance against financial distress, which is based on ex ante measures of default probabilities of individual banks and forecasted asset return correlations. Importantly, using realized correlations estimated from high-frequency equity return data can significantly improve the accuracy of forecasted correlations. Our stress testing methodology, using an integrated micro–macro model, takes into account dynamic linkages between the health of major US banks and macro-financial conditions. Our results suggest that the theoretical insurance premium that would be charged to protect against losses that equal or exceed 15% of total liabilities of 12 major US financial firms stood at $110 billion in March 2008 and had a projected upper bound of $250 billion in July 2008.     

Assessing financial contagion in the interbank market: Maximum entropy versus observed interbank lending patterns

Interbank markets allow banks to cope with specific liquidity shocks. At the same time, they may represent a channel for contagion as a bank default may spread to other banks through interbank linkages. This paper analyses how contagion propagates within the Italian interbank market using a unique data set including actual bilateral exposures. Based on the availability of information on actual bilateral exposures for all Italian banks, the results obtained by assuming the maximum entropy are compared with those reflecting the observed structure of interbank claims. The comparison indicates that, under certain circumstances, depending on the structure of the interbank linkages, the recovery rates of interbank exposures and banks’ capitalisation, the maximum entropy approach overrates the scope for contagion.     

Systemically important banks and financial stability: The case of Latin America

This paper addresses the issue on how bank size and market concentration affect performance and risks in 17 Latin American countries between 2001 and 2008. The objective is to evaluate whether a too-big-to-fail behavior has been present in the region. Surprisingly, we do not find evidence to support a higher fragility of large Latin American banks. Our results show that systemically important financial institutions appear to outperform others in terms of both cost and profit without the need of taking more risks. This result holds even in concentrated markets, i.e., where there are few dominant banks and many others with small size in relation to the market. A highly unequal banking market in terms of assets, however, is detrimental for the performance of smaller banks and it also decreases stability of the whole system. We conclude that regulators should deal with market concentration by reducing the size gap between large and small banks, instead of dealing specifically with systemically important banks.     

Deposit insurance, bank regulation, and financial system risks

Empirical evidence is presented to show that in modern times banks can hedge liquidity shocks but could not do so prior to FDIC insurance. However, the government's limitations in properly pricing FDIC insurance are leading to many current examples of moral hazard. A model is presented to show that if insurance premiums are set to be “actuarially fair,” incentives for banks to take excessive systematic risks remain. Motivated by empirical evidence that money market mutual funds also can hedge liquidity shocks, I consider an alternative government insurance system that mitigates distortions to risk-taking yet preserves liquidity hedging and information synergies.     

Hedge funds,CDOs and the financial crisis: An empirical investigation of the “Magnetar trade”

The so called Magnetar trade (a kind of capital structure arbitrage on the US housing market, using CDS and synthetic CDOs, and exploiting rating-dependent mispricing of risk) has gained a high publicity due to a Pulitzer Prize awarded media story from two journalists of ProPublica (an online news outlet). The story essentially claimed that the mortgage investment strategy of the hedge fund Magnetar during the period between 2006 and mid 2007 was based on a desire to construct CDO deals with riskier assets so that they could place bets that portions of their own deals would fail. This paper provides several pieces of evidence in line with the argument that tranches from Magnetar-sponsored CDOs present overly risky investments. However, investors and rating agencies appear to have adjusted their required spread levels and ratings to reflect this higher riskiness, at least to some extent.     

Dynamic debt runs and financial fragility: Evidence from the 2007 ABCP crisis

We use the 2007 asset-backed commercial paper (ABCP) crisis as a laboratory to study the determinants of debt runs. Our model features dilution risk: maturing short-term lenders demand higher yields in compensation for being diluted by future lenders, making runs more likely. The model explains the observed tenfold increase in yield spreads leading to runs and the positive relation between yield spreads and future runs. Results from structural estimation show that runs are very sensitive to leverage, asset values, and asset liquidity, but less sensitive to the degree of maturity mismatch, the strength of guarantees, and asset volatility.     

Market discipline, financial crisis and regulatory changes: Evidence from Indonesian banks

Following the 1997/1998 financial crisis, Indonesian banks experienced major regulatory changes, including the adoption of the blanket guarantee scheme (BGS) in 1998, a limited guarantee (LG) in 2005, and changes in capital regulation in 1998 and 2001. We examine the impact of these regulatory changes on market discipline during the period 1995-2009. The price of deposits is used to measure market discipline in a dynamic panel data methodology on a sample of 104 commercial banks. We find a weakening of market discipline following the introduction of the BGS. The result is consistent with the deposit insurance scheme being credible in the lower capital requirement environment. The adoption of LG in a recovering economy also mitigates the role of market discipline. However, market discipline is more pronounced in listed banks than unlisted banks and in foreign banks than domestic banks. These results have important implications for banking regulation and supervision, particularly during a crisis period.     

Consolidation in banking and financial stability in Europe: Empirical evidence

Using aggregate balance sheet data from banks across the EU-25 over the period from 1997 to 2005 we provide empirical evidence that national banking market concentration has a negative impact on European banks’ financial soundness as measured by the Z-score technique while controlling for macroeconomic, bank-specific, regulatory, and institutional factors. Furthermore, our analysis reveals that Eastern European banking markets exhibiting a lower level of competitive pressure, fewer diversification opportunities and a higher fraction of government-owned banks are more prone to financial fragility whereas capital regulations have supported financial stability across the entire European Union.     

Credit risk transfer activities and systemic risk: How banks became less risky individually but posed greater risks to the financial system at the same time

A main cause of the crisis of 2007-2009 is the various ways through which banks have transferred credit risk in the financial system. We study the systematic risk of banks before the crisis, using two samples of banks respectively trading Credit Default Swaps (CDS) and issuing Collateralized Loan Obligations (CLOs). After their first usage of either risk transfer method, the share price beta of these banks increases significantly. This suggests the market anticipated the risks arising from these methods, long before the crisis. We additionally separate this beta effect into a volatility and a market correlation component. Quite strikingly, this decomposition shows that the increase in the beta is solely due to an increase in banks’ correlations. Thus, while banks may have shed their individual credit risk, they actually posed greater systemic risk. This creates a challenge for financial regulation, which has typically focused on individual institutions.     

The pernicious effects of contaminated data in risk management

Banks hold capital to guard against unexpected surges in losses and long freezes in financial markets. The minimum level of capital is set by banking regulators as a function of the banks’ own estimates of their risk exposures. As a result, a great challenge for both banks and regulators is to validate internal risk models. We show that a large fraction of US and international banks uses contaminated data when testing their models. In particular, most banks validate their market risk model using profit-and-loss (P/L) data that include fees and commissions and intraday trading revenues. This practice is inconsistent with the definition of the employed market risk measure. Using both bank data and simulations, we find that data contamination has dramatic implications for model validation and can lead to the acceptance of misspecified risk models. Moreover, our estimates suggest that the use of contaminated data can significantly reduce (market-risk induced) regulatory capital.     

Concentrated control,institutions, and banking sector: An international study

Using a broad sample of listed commercial banks in East Asia and Western Europe, this paper investigates the relations among concentrated control, a set of bank operating characteristics, and legal and regulatory regimes. We find that banks with concentrated control exhibit poorer performance, lower cost efficiency, greater return volatility, and higher insolvency risk, relative to widely held ones. We also document that legal institutions and private monitoring effectively reduce the detrimental effects of concentrated control and that official disciplinary power plays a weak governance role, whereas government intervention exacerbates the adverse effects. Further evidence shows that the relations between control concentration and bank operating characteristics are curvilinear and vary according to the types of controlling owners. Overall, our findings support the contention that country-level institutions play important roles in constraining insider expropriation, and that private monitoring mechanisms are more effective than are public rules and supervision in governing banks.     

A perspective on the symptoms and causes of the financial crisis

Prior to the 2007–2008 financial crisis, banking sector profits were very high but the profitability of financial intermediation was poor. Using a novel model of banking, this article argues that the high profits were achieved through balance sheet expansion and growing default, liquidity, and term risk mismatches between assets and liabilities. As a result, large banks’ financial leverage rose as they became less liquid, setting the conditions for a systemic banking crisis. This article argues that the increase in financial leverage was possible due to misguided changes in the regulatory framework, specifically, the Basel I capital accord and reductions in reserve requirements. Finally, this article overviews and assesses the policy response in the aftermath of the crisis.     

Liquidity risk management and credit supply in the financial crisis

Liquidity dried up during the financial crisis of 2007-2009. Banks that relied more heavily on core deposit and equity capital financing, which are stable sources of financing, continued to lend relative to other banks. Banks that held more illiquid assets on their balance sheets, in contrast, increased asset liquidity and reduced lending. Off-balance sheet liquidity risk materialized on the balance sheet and constrained new credit origination as increased takedown demand displaced lending capacity. We conclude that efforts to manage the liquidity crisis by banks led to a decline in credit supply.     

Liquidity Provision,Bank Capital,and the Macroeconomy

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).     

Risk management,corporate governance,and bank performance in the financial crisis

The recent financial crisis has raised several questions with respect to the corporate governance of financial institutions. This paper investigates whether risk management-related corporate governance mechanisms, such as for example the presence of a chief risk officer (CRO) in a bank’s executive board and whether the CRO reports to the CEO or directly to the board of directors, are associated with a better bank performance during the financial crisis of 2007/2008. We measure bank performance by buy-and-hold returns and ROE and we control for standard corporate governance variables such as CEO ownership, board size, and board independence. Most importantly, our results indicate that banks, in which the CRO directly reports to the board of directors and not to the CEO (or other corporate entities), exhibit significantly higher (i.e., less negative) stock returns and ROE during the crisis. In contrast, standard corporate governance variables are mostly insignificantly or even negatively related to the banks’ performance during the crisis.     

Bank capital regulation in a barrier option framework

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.     

Bank ownership reform and bank performance in China

Using a panel of Chinese banks over the 1997–2004 period, we assess the effect of bank ownership on performance. Specifically, we conduct a joint analysis of the static, selection, and dynamic effects of (domestic) private, foreign and state ownership. We find that the “Big Four” state-owned commercial banks are less profitable, are less efficient, and have worse asset quality than other types of banks except the “policy” banks (static effect). Further, the banks undergoing a foreign acquisition or public listing record better pre-event performance (selection effect); however, we find little performance change in either the short or the long term.     

Improvements in loss given default forecasts for bank loans

An accurate forecast of the parameter loss given default (LGD) of loans plays a crucial role for risk-based decision making by banks. We theoretically analyze problems arising when forecasting LGDs of bank loans that lead to inconsistent estimates and a low predictive power. We present several improvements for LGD estimates, considering length-biased sampling, different loan characteristics depending on the type of default end, and different information sets according to the default status. We empirically demonstrate the capability of our proposals based on a data set of 69,985 defaulted bank loans. Our results are not only important for banks, but also for regulators, because neglecting these issues leads to a significant underestimation of capital requirements.     

Market discipline during crisis: Evidence from bank depositors in transition countries

The Central European banking industry is dominated by foreign-owned banks. During the recent crisis, for the first time since the transition, foreign parent companies were frequently in a worse financial condition than their subsidiaries. This situation created a unique opportunity to study new aspects of market discipline exercised by non-financial depositors. Using a comprehensive data set, we find that the recent crisis did not change the sensitivity of deposit growth rates to accounting risk measures. We establish that depositors’ actions were more strongly influenced by negative press rumors concerning parent companies than by fundamentals. The impact of rumors was especially perceptible when rumors turned out ex post to be founded. Additionally, we document that public aid announcements were primarily interpreted by depositors as confirmation of a parent company’s financial distress. Our results indicate that depositors react rationally to sources of information other than financial statements; this discovery has policy implications, as depositor discipline is usually the only viable and universal source of market discipline for banks in emerging economies.
