Credit risk modeling in segmented portfolios: an application to credit cards
The Great Recession offers a unique opportunity to analyze the performance of credit risk models under conditions of economic stress. We focus on the performance of models of credit risk applied to risk-segmented credit card portfolios. Specifically, we focus on models of default and loss and analyze three important sources of model risk: model selection, model specification, and sample selection. Forecast errors can be significant along any of these three model-risk dimensions. Simple linear regression models are not generally outperformed by more complex or stylized models. The impact of ...

Flight to Liquidity or Safety? Recent Evidence from the Municipal Bond Market
We examine the effects of the COVID-19 pandemic and subsequent monetary and fiscal policy actions on municipal bond market pricing. Using high-frequency trading data, we estimate key policy events at the peak of the crisis by focusing on a sample of bonds within a narrow window before and after each policy event. We find that policy interventions, in particular those with explicit credit backstops, were effective in alleviating municipal bond market stress. Next, we exploit daily variation in traded municipal bonds and virus exposure across U.S. counties. We find a shift in how bond investors ...

Understanding the Exposure at Default Risk of Commercial Real Estate Construction and Land Development Loans
We study and model the determinants of exposure at default (EAD) for large U.S. construction and land development loans from 2010 to 2017. EAD is an important component of credit risk, and commercial real estate (CRE) construction loans are more risky than income producing loans. This is the first study modeling the EAD of construction loans. The underlying EAD data come from a large, confidential supervisory dataset used in the U.S. Federal Reserve’s annual Comprehensive Capital Assessment Review (CCAR) stress tests. EAD reflects the relative bargaining ability and information sets of ...

What Drives the Cross-Section of Credit Spreads?: A Variance Decomposition Approach
I decompose the cross-sectional variation of the credit spreads for corporate bonds into changing expected returns and changing expectation of credit losses with a model-free method. Using a log-linearized pricing identity and a vector autoregression applied to micro-level data from 1973 to 2011, I find that the expected credit loss component and the excess return component each explains about half of the variance of the credit spreads. Unlike the market-level findings in Gilchrist and Zakrajsek (2012), at the firm level, the expected credit loss is volatile and affects the firms' investment ...

Forecasting credit card portfolio losses in the Great Recession: a study in model risk
Credit card portfolios represent a significant component of the balance sheets of the largest US banks. The charge?off rate in this asset class increased drastically during the Great Recession. The recent economic downturn offers a unique opportunity to analyze the performance of credit risk models applied to credit card portfolios under conditions of economic stress. Specifically, we evaluate three potential sources of model risk: model specification, sample selection, and stress scenario selection. Our analysis indicates that model specifications that incorporate interactions between policy ...

Debt Maturity and Commitment on Firm Policies
When firms can trade debt only at discrete dates, debt maturity becomes an effective tool to address the commitment problem related to debt and investment policies. In the absence of other market frictions, single-period debt restores first-best investment. With market freezes, underinvestment worsens the leverage ratchet effect, which in turn increases investment distortions for long debt maturities. A calibrated model shows that choosing the right maturity can reduce the cost of commitment problems and market frictions by up to 4% of firm value. A decomposition of the equilibrium credit ...

On the Economics of Discrimination in Credit Markets
This paper develops a general equilibrium model of both taste-based and statistical discrimination in credit markets. We find that both types of discrimination have similar predictions for intergroup differences in loan terms. The commonly held view has been that if there exists taste-based discrimination, loans approved to minority borrowers would have higher expected profitability than to majorities with comparable credit background. We show that the validity of this profitability view depends crucially on how expected loan profitability is measured. We also show that there must exist ...

The Bank as Grim Reaper : Debt Composition and Bankruptcy Thresholds
We offer a model and evidence that private debtholders play a key role in setting the endogenous asset value threshold below which corporations declare bankruptcy. The model, in the spirit of Black and Cox (1976), implies that the recovery rate at emergence from bankruptcy on all of the firm's debt taken together is increasing in the pre-bankruptcy share of private debt in all debt. Empirical evidence supports this and other implications of the model. Indeed, debt composition has a more economically material empirical influence on recovery than all other variables we try taken together.

Why Did the Recent Oil Price Declines Affect Bond Prices of Non-Energy Companies?
Oil prices plunged 65 percent between July 2014 and December of the following year. During this period, the yield spread?the yield of a corporate bond minus the yield of a Treasury bond of the same maturity?of energy companies shot up, indicating increased credit risk. Surprisingly, the yield spread of non?energy firms also rose even though many non?energy firms might be expected to benefit from lower energy?related costs. In this blog post, we examine this counterintuitive result. We find evidence of a liquidity spillover, whereby the bonds of more liquid non?energy firms had to be sold to ...
