Is collateral at all valuable to creditors in corporate lending? At one level, it is clear why collateral should be important for lenders: it consists of hard assets that are not subject to asymmetric valuations in markets and that the borrower cannot alter easily. Collateral gives comfort to a lender that, even if the lender does little to monitor the borrower’s activity and the borrower’s cash flows prove inadequate to service the debt, the lender’s claim is protected by underlying value.

Yet even if assets are important to lending, why does debt need to be secured by them? After all, in a bankruptcy filing the firm’s assets will all be there to support the lender’s claim. Why protect the lender further through claims on specific collateral? In a related work (The Decline of Secured Debt), we find that firms tend to issue more secured debt when their credit quality is low or at times when average credit spreads across firms are higher or economic growth is slower. These are times when firms may find access to credit more difficult, creditors may fear greater stockholder-debtholder conflicts, and borrowers may need to collateralize debt issuances in order to regain access to funding. Moreover, with new lenders unwilling to lend without the comfort of collateral, existing lenders might rush to secure their claims so as not to be diluted. Indeed, negative pledge clauses (whereby the borrower commits to a lender that it will not issue secured debt to any other lender, failing which the debt payment will be accelerated) allow creditors to large companies to stay unsecured until they sense a greater likelihood of borrower distress, at which point they will move to secure their claims.

If collateral matters to creditors for the enforcement of debt claims, even in the case of large, mature companies but in a more contingent way, we should see it reflected in the pricing of secured claims vis-à-vis unsecured claims, especially in how that pricing moves with the state of the firm and the economy. Security should be of little value to lenders when a firm is far from distress or the economy is healthy, and it should become much more valuable (and hence secured debt should promise lower interest rates than unsecured debt) as a firm nears distress or the economy deteriorates.

The difficulty in identifying the effects of security on debt pricing derives from the circumstances under which it is offered. Since riskier firms will offer security at riskier times, a comparison of rates offered by secured debt issuances against rates offered by unsecured debt issuances across firms, or by the same firm over time, will tend to be biased toward suggesting higher rates for secured debt issuances.

In this paper, we use multiple data sets to get at the true pricing of secured debt, stripped as best as possible of the selection bias. Our identification strategy compares spreads on secured and unsecured credit of the same firm and at the same point in time.

We conclude from all these ways of obtaining the value of security that the selection bias is important, and correcting for it suggests that security is valuable to creditors – creditors typically require a lower spread when their claim is secured. Most important, however, we show that creditors value security differently for different firms and at different times.

For highly rated firms, creditors pay almost nothing for the added protection afforded by security, whereas for low-rated firms, they pay a lot. Yields on bonds issued by investment grade firms (those with an S&P rating of BBB− or better) are 20 basis points lower when secured, whereas this yield differential (unsecured versus secured) jumps to 112 basis points for a firm having a non-investment grade rating. Similarly, implied yields from bond trades in secondary market suggest that investors are willing to give up almost 161 basis points in spread for the added protection of security for non-investment grade issuers, whereas they are not willing to reduce spread at all for the added protection of security in the case of investment grade issuers.

Equally important, as a firm’s credit quality deteriorates, we see the valuation of secured claims improve relative to unsecured claims, suggesting that security becomes more valuable. We also find that secured spreads decline relative to unsecured spreads as the economy’s health – as reflected in GDP growth or the economywide Baa–Aaa spread – deteriorates.

The upshot is that collateral does not seem to matter for debt enforcement in normal times for a healthy firm, since debt linked to specific assets do not seem to enjoy better prices. Indeed, given the negligible pricing benefit, firms may want to avoid any loss in financial slack and operational flexibility at such times by not issuing secured debt. However, in tougher times, creditors do seem to value security, and firms do issue secured debt, either because creditors demand it or because of the better pricing.

Disruption and Credit Markets

By Bo Becker (Stockholm School of Economics) and Victoria Ivashina (Harvard Business School)

Corporate bond defaults have been on a long and powerful upward trajectory in the past few decades. The default rate of U.S. corporate bonds rose from 0.12 percent to 0.46 percent between the first and second halves of the period from 1970 to 2016—an increase of almost four times. The rating agency Moody’s reports that, of the ten years with the highest default rates since 1960, six occurred in the new millennium and none before 1990. In a recent working paper, we investigate the role of disruption in explaining this trend.

By disruption, we refer to the process whereby new firms replace old firms using innovations in their business models, operations, or new technology. This process causes incumbent firms to lose market share, suffer reduced profitability, and, as we demonstrate, default on debt obligations. Just to name a few of the many recent examples: single-location bookstores were disrupted by chain stores, which were in turn disrupted by online bookstores, and off-line travel agents were disrupted by online services.

In our study, we compare industries with high rates of arrival of new firms, measured as either venture capital investments in the sector over the last five years or as the fraction of public firms in the industry with an IPO date in the past five years. The two variables capture different stages of disruptors’ ascent. While one can easily think of several broad forces that have increased innovation and disruption over the past few decades, different industries have been affected at different speed and different depth. We exploit this variation to draw the connection between disruption and defaults.

Our measures of disruption positively predict future defaults on corporate bonds, controlling for a host of other factors (including time, industry, bond characteristics such as seniority and callability, and issuer characteristics such as credit rating). These bonds are largely issued by mature firms (startups rarely access the bond market). Not only are future defaults higher in industries with high rates of disruption, but the bond market prices this in: newly issued bonds in high-disruption industries have higher yields. These findings are surprising, as a reasonable expectation might be that firms in the same industry would generally suffer similar fates. We would then expect to see high rates of new firm creation coupled with low defaults on the debt (of incumbents). Instead, we find the opposite.

An active IPO market and elevated venture capital investment may help the inception and advancement of potential disruptors, but underlying causes may be found in technological shifts (information technology, mobile, and ,in an earlier era, perhaps electricity), deregulation (think airlines), and globalization (in our data, industries directly exposed to off-shoring are no more likely to see defaults; however, global markets may have an important role in scaling up the opportunities available for disruptive businesses).

The importance of disruption probably extends beyond creditors to other stakeholders of incumbent firms. The corporate bond market is useful for studying disruption because bonds are liquid securities with detailed, high-quality data. Furthermore, losses on corporate bonds are important because bonds are widely held. This is in contrast with the gains from disruption, which tend to be concentrated with entrepreneurs and venture capital investors.

OECD Report on Corporate Bond Markets in a Time of Unconventional Monetary Policy

By Ryan M. Rossner (Harvard Law School, J.D. 2019)

On February 25, the OECD published another report in its Capital Market Series, Corporate Bond Markets in a Time of Unconventional Monetary Policy, which noted both a significant increase of outstanding nonfinancial corporate debt and a simultaneous decrease in bond quality post-financial crisis. Authored by Mats Isaksson, Serdar Çelik, and Gul Demirtaş, the report drew upon a dataset of almost 85,000 unique corporate bond issues by nonfinancial companies from 114 countries between 2000 and 2018.

The report provides a detailed account of capital markets development post-financial crisis with comparisons among different jurisdictions.  The authors emphasize that levels of nonfinancial corporate bond issuances have reached record highs. Global outstanding debt in the form of corporate bonds issued by nonfinancial companies reached almost $13 trillion USD at the end of 2018, twice the amount in real terms than was outstanding in 2008.  The report links the expansion of corporate bond issuances to regulatory initiatives aimed at encouraging corporate bond issuances, expansionary monetary policy, and (particularly in the EU) quantitative easing.  The report also forecasted a record repayment period ahead with $2.9 trillion coming due for advanced economy issuers and $1.3 trillion for emerging economy issuers within 3 years.

The US remains the largest corporate bond market and US issuers raised the most funds over the period.  However, the authors found that the number of US nonfinancial issuers increased only modestly in the post-crisis era, suggesting increased issuer concentration in US primary corporate bond markets. Over the same period, Japan, the EU, Korea, and China all increased both their use of corporate bond issuances as a means of borrowing and their number of issuers. Most strikingly, the number of Chinese companies issuing bonds increased steeply from 68 issuers in 2007 to a peak of 1,451 in 2016.

Amidst the expansion, the authors found a marked decrease in bond quality. To support these conclusions, the authors pointed to a marked expansion of non-investment grade bonds, and the increase of BBB-rated bonds (the rating just above non-investment grade) as a percentage of investment grade debt (to 54% in 2018).

The report also noted a decrease in covenant protection for non-investment grade corporate bonds. The authors devised a “Covenant Protection Index” of US issuances, by looking at the presence or absence of 27 different types of covenants in bond indentures.  While the index is a rough measure of covenant protection, it demonstrated a downward trend for non-investment grade bonds.  The authors attribute the decrease in covenant protections to increased issuer bargaining power in a low interest rate environment, as investors have been willing to forgo certain protections in favor of higher yields.

The authors note that the combination of increased bond issuances, a “prolonged period of low issuer quality,” and “lower levels of covenant protection” for noninvestment grade bonds suggest that in an economic downturn the amount of expected future corporate bond defaults “may be considerably larger than that experienced in the financial crisis.” This report comes shortly after Federal Reserve Chairman Jay Powell, during the January FOMC meeting press conference, described the current state of corporate debt as a “macroeconomic risk,” which could “amplify” a negative downturn.

The Anatomy of Distressed Debt Markets

By Edward I. Altman (New York University) & Robert Benhenni (Pole Universitaire Leonard de Vinci)

The market for investing in distressed securities, the so-called “vulture” markets, has captured the interest of increasing numbers of investors and analysts. These investors, sometimes categorized as “alternative asset” institutions, mainly hedge funds, now can convincingly argue that the market has matured into a genuine asset class, with a reasonably long history of data on return and risk attributes.

In earlier works, Professor Altman has helped to classify this market into two distinct categories: (1) “Distressed” debt, meaning bonds or loans whose yield to maturity (later amended to option-adjusted yield) was equal to or greater than 10% above the 10-year U.S. government bond rate (later amended to be the U.S. government bonds with comparable duration), and (2) “Defaulted” debt, referring to bonds or loans of firms who have defaulted on their debt obligations and were in their restructuring (usually Chapter 11) phase.

The purpose of this article is to document the descriptive anatomy of the distressed debt markets size, growth, major strategies, characteristics, and participants, and then to explore its performance attributes, reviewing the relevant 30-year period from 1987-2017.  The article notes a number of unique aspects which make this asset class attractive, especially to hedge fund managers who can move in and out of the securities depending upon the credit cycle.
