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.     

Counter-cyclical substitution between trade credit and bank credit

This paper explores the substitution relationship between trade credit and bank credit, and its counter-cyclic dynamic pattern through economic cycles. We propose a new theoretical model, using a mechanism design method, which predicts the substitution between the two credits and its counter-cyclic behavior, subject to the condition of technological efficiency not less than one. This model also helps explain the somewhat contradictory evidence in the literature, on the relationship between the two credits. We present empirical evidence on the substitution effect and its counter-cyclic behavior, by using a balanced panel data set of 284 listed Chinese companies for the period 1998-2006. We further find that the substitution behaves counter-cyclically with respect to the coincident macroeconomic indicator, namely, GDP. Our empirical analysis also has some new features such as treating endogeneity carefully and incorporating the lag-effect of trade credit coherently.     

Liquidity risk and policy options

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.     

Consumption and risk sharing over the life cycle

A striking feature of U.S. data on income and consumption is that inequality increases with age. This paper asks if individual-specific earnings risk can provide a coherent explanation. We find that it can. We construct an overlapping generations general equilibrium model in which households face uninsurable earnings shocks over the course of their lifetimes. Earnings inequality is exogenous and is calibrated to match data from the U.S. Panel Study on Income Dynamics. Consumption inequality is endogenous and matches well data from the U.S. Consumer Expenditure Survey. The total risk households face is decomposed into that realized before entering the labor market and that realized throughout the working years. In welfare terms, the latter is found to be more important than the former.     

Bank loan loss accounting treatments,credit cycles and crash risk

Banks that follow conditional conservatism in their loan loss accounting treatments benefit from a reduction in crash risk. The key discretionary loan loss accounting channels are provisions and allowances. We show that conditional conservatism reduces crash risk of small banks during periods of credit contraction and boom. Interestingly, for large banks, crash risk is not reduced by more conservative accounting even for those with higher levels of opacity. Hence regulation prompting for more conservative bank loan loss accounting does not present a significant opportunity to limit systemic effects arising from abrupt price declines in the stocks of large banks.     

Business credit information sharing and default risk of private firms

We investigate whether and how business credit information sharing helps to better assess the default risk of private firms. Private firms represent an ideal testing ground because they are smaller, more informationally opaque, riskier, and more dependent on trade credit and bank loans than public firms. Based on a representative panel dataset that comprises private firms from all major industries, we find that business credit information sharing substantially improves the quality of default predictions. The improvement is stronger for older firms and those with limited liability, and depends on the sharing of firms’ payment history and the number of firms covered by the local credit bureau office. The value of soft business credit information is higher the smaller the firms and the lower their distance from the local credit bureau office. Furthermore, in spatial and industry analyses we show that the higher the value of business credit information the lower the realized default rates. Our study highlights the channel through which business credit information sharing adds value and the factors that influence its strength.     

Bank CEO incentives and the credit crisis

We investigate whether bank performance during the recent credit crisis is related to chief executive officer (CEO) incentives before the crisis. We find some evidence that banks with CEOs whose incentives were better aligned with the interests of shareholders performed worse and no evidence that they performed better. Banks with higher option compensation and a larger fraction of compensation in cash bonuses for their CEOs did not perform worse during the crisis. Bank CEOs did not reduce their holdings of shares in anticipation of the crisis or during the crisis. Consequently, they suffered extremely large wealth losses in the wake of the crisis.     

Stress testing credit risk: The Great Depression scenario

By employing Moody’s corporate default and rating transition data spanning the last 90 years we explore how much capital banks should hold against their corporate loan portfolios to withstand historical stress scenarios. Specifically, we will focus on the worst case scenario over the observation period, the Great Depression. We find that migration risk and the length of the investment horizon are critical factors when determining bank capital needs in a crisis. We show that capital may need to rise more than three times when the horizon is increased from 1 year, as required by current and future regulation, to 3 years. Increases are still important but of a lower magnitude when migration risk is introduced in the analysis. Further, we find that the new bank capital requirements under the so-called Basel 3 agreement would enable banks to absorb Great Depression-style losses. But, such losses would dent regulatory capital considerably and far beyond the capital buffers that have been proposed to ensure that banks survive crisis periods without government support.     

Asymmetric effects of the business cycle on bank credit risk

Prior empirical research on the relation between credit risk and the business cycle has failed to properly investigate the presence of asymmetric effects. To fill this gap, we examine this relation both at the aggregate and the bank level exploiting a unique dataset on Italian banks’ borrowers’ default rates. We employ threshold regression models that allow to endogenously establish different regimes identified by the thresholds over/below which credit risk is more/less cyclical. We find that not only are the effects of the business cycle on credit risk more pronounced during downturns but cyclicality is also higher for those banks with riskier portfolios.     

Corporate trade credit and inventories: New evidence of a trade-off from accounts payable and receivable

Trade credit is an important source of finance for firms and has been well researched, but the focus has been on financial trade-offs. In this paper, we consider the trade-offs with inventories and develop a simple model that recognizes the incentives a firm faces to offer and receive trade credit. Our model identifies the response of accounts payable and accounts receivable to changes in the cost of inventories, profitability, risk and liquidity, and importantly, this influence operates through a production channel. Our results support the model and complement many existing studies focused on explaining the financial terms of trade credit.     

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.     

Trade credit,cash holdings,and financial deepening: Evidence from a transitional economy

This paper investigates the effect of financial deepening on the relationship between trade credit and cash holdings among Chinese listed firms. We first document an asymmetric effect of trade payables and receivables on cash holdings, in that firms hold an additional $0.71 of cash for every $1 of credit payable but use $1 of receivables as a substitute for only $0.15 of cash. We then find that firms in regions with higher levels of financial deepening hold less cash for payables while substituting more receivables for cash. A more highly developed financial sector helps firms to better use trade credit as a short-term financing instrument. Finally, we find that the ratio at which receivables are substituted for cash increased following the implementation of the new receivables pledge policy in 2007, which allowed firms to use receivables as security for loans. This policy event represents an exogenous shock that mitigates the endogeneity concern.     

Costly external finance,corporate investment,and the subprime mortgage credit crisis

We study the effect of the recent financial crisis on corporate investment. The crisis represents an unexplored negative shock to the supply of external finance for non-financial firms. Corporate investment declines significantly following the onset of the crisis, controlling for firm fixed effects and time-varying measures of investment opportunities. Consistent with a causal effect of a supply shock, the decline is greatest for firms that have low cash reserves or high net short-term debt, are financially constrained, or operate in industries dependent on external finance. To address endogeneity concerns, we measure firms’ financial positions as much as four years prior to the crisis, and confirm that similar results do not follow placebo crises in the summers of 2003–2006. Nor do similar results follow the negative demand shock caused by September 11, 2001. The effects weaken considerably beginning in the third quarter of 2008, when the demand-side effects of the crisis became apparent. Additional analysis suggests an important precautionary savings motive for seemingly excess cash that is generally overlooked in the literature.     

Liquidity risk and syndicate structure

We decompose syndicated loan risk into credit, market, and liquidity risk and test how these shape syndicate structure. Commercial banks dominate relative to non-banks in loan syndicates that expose lenders to liquidity risk. This dominance is most pronounced when borrowers have high levels of credit or market risk. We then tie commercial banks’ advantage in liquidity risk to access to transactions deposits by comparing investments across banks. The results suggest that risk-management considerations matter most for participants relative to lead arrangers. Links from transactions deposits to liquidity exposure, for instance, are more than 50% larger at participants than at lead arrangers.     

The use of bank lines of credit in corporate liquidity management: A review of empirical evidence

This paper reviews empirical evidence on the use of bank lines of credit as a source of corporate liquidity. Traditional explanation for lines of credit is that they provide insurance against liquidity shocks, in much the same as way hoarding cash does. However, recent empirical research suggests that access to lines of credit is contingent on the credit quality of the borrower as well as the financial condition of the lender. These findings suggest that lines of credit are an imperfect substitute for cash as a source of corporate liquidity.     

Foreign bank entry and firms’ access to bank credit: Evidence from China

This paper studies the impact of foreign bank entry on domestic firms’ access to bank credit using a within-country staggered geographic variation in the policy of foreign bank lending in China. The paper finds that after foreign bank entry profitable firms use more long-term bank loans; whereas firms with higher value of potential collateral do not. It also finds that non-state-owned firms become able to substitute some trade credit with long-term bank loans. The findings suggest that less opaque firms and non-state-owned firms benefit more from foreign bank entry and that collateral may only play a limited role in mitigating the problem of information asymmetry when creditors’ rights are not well protected in a host country.     

Product market competition and credit risk

This study theoretically and empirically investigates effects of product market competition on credit risk. We first develop a real-options-based structural model in a homogeneous oligopoly and show that credit spreads are positively related to the number of firms in an industry. The disparity of firm size in an industry is relevant to both product market competition and credit risk, and we therefore extend the model to an asymmetric duopoly case. In particular, we demonstrate that credit spreads of relatively small (large) firms within an industry are positively (negatively) related to Herfindahl-Hirschman index, and the relative firm size in an industry is an important determinant of credit risk. The models’ implications are empirically scrutinized by a reduced-form hazard model and generally supported. By performing out-of-sample analyses, the results demonstrate that firm size together with the interaction terms between intra-industry firm size dummies and competition intensity can effectively predict default.     

Interaction of market and credit risk

Experience during the financial crisis illustrates that the integrated measurement and management of different forms of risk remains a challenge for industry practitioners, researchers and financial supervisors alike. In the context of related literature, this article summarizes new research on the interaction of market and credit risk and implications for risk management that is presented in this special issue. The research covered highlights in particular the errors that can occur in the aggregation of the two types of risk and the strong relationships between them that suggest caution in the use of pragmatic distinctions between them. The article also touches on some research-based lessons for supervisory policies and suggests some directions for future research.     

Relationship lending,hierarchical distance and credit tightening: Evidence from the financial crisis

This paper examines the firms’ credit availability during the 2007–2009 financial crisis using a dataset of 5331 bank–firm relationships provided by borrowers’ credit folders of three Italian banks. It aims to test whether a strong lender–borrower relationship can produce less credit rationing for borrowing firms even during a credit crunch period. The results show that exclusivity of the relationship can mitigate the firm credit rationing. We also verify the influence of lending organizational structure during crisis. A new measure of distance in lending technologies has been introduced: the hierarchical distance calculated as the distance between the branch that originates the loan and the location of the hierarchical level responsible for financing decision. Our findings document a negative impact of distance on credit availability, consistent with the idea that proximity facilitates the transmission of soft information.     

Recovery rates,default probabilities,and the credit cycle

In recessions, the number of defaulting firms rises. On top of this, the average amount recovered on the bonds of defaulting firms tends to decrease. This paper proposes an econometric model in which this joint time-variation in default rates and recovery rate distributions is driven by an unobserved Markov chain, which we interpret as the “credit cycle”. This model is shown to fit better than models in which this joint time-variation is driven by observed macroeconomic variables. We use the model to quantitatively assess the importance of allowing for systematic time-variation in recovery rates, which is often ignored in risk management and pricing models.
