relationship between default risk and interest rates

Default risk affects the interest rate charged on a debt instrument. The difference in the promised yield between a corporate bond and a government bond with. The risk of default on principal or interest, or both, is greater for high-yield bonds This chart tracks the annual default loss rate in high-yield bonds since A difference may exist between the prices buyers are bidding and the prices. Jun 17, This study empirically examines the relationship between interest rates and default risk using firm level corporate default data in the United.

On the other hand, a firm operating in a risky environment will be less likely to default if the debt service payments relative to its operating cash flows are modest. In addition, the longer the firm has been operating without creditors incurring losses, the lower the default risk.

The longer the firm has sustained operations, the lower the default risk. The greater the chance that the company will experience financial distress, the higher the default premium required by investors.

The default risk premium is typically measured by comparing the yield on a long-term Treasury bond with a long-term corporate security that is comparable to the Treasury security in all material respects. The difference in the two yields serves as a proxy for the default premium. There is a cyclical nature to default premiums.

Credit Risk versus Interest Rate Risk

In general, the yield spread narrows during periods of economic prosperity, and widens during economic downturns. A rationale for this phenomenon is that investors may be more willing to take on additional risk during times of prosperity, thus requiring less yield from lower-rated bonds.

On the other hand, during economic downturns, investors are more interested in security, and thus require higher yields from riskier, lower-rated bonds. Patterns in default rates reflect a firm's life cycle. Lower-rated issuers—smaller, younger, and more heavily leveraged firms—tend to have wider credit spreads that narrow with maturity. Higher-rated firms—more mature and stable—tend to have narrower credit spreads that widen with maturity.

Bond ratings have provided a good guide in gauging the risk of default. Default rates are very low for higher-rated bonds, and increase as the bond ratings decline.

The higher the rating, the smaller the number of issues that subsequently default. With lower ratings, the default percentage increases dramatically. Thus, the default premium widens as the ratings decrease. A number of studies have examined the relationship between bond ratings and the financial variables of firms.

These studies have found higher debt ratings assigned to the bonds of firms that have lower debt ratios, higher interest coverage ratios, higher returns on assets, lower variability in earnings per share over time, and lower use of subordinated debt.

Accordingly, the bonds of firms having these characteristics would be expected to have a lower risk of default. Once a bond rating has been established, it can change because of either an improvement or deterioration in the company's fortunes. In recent years, the number of downgraded bond ratings has exceeded the number of upgradings. The inclination of a deterioration in credit quality reflects to a certain extent the greater use of financial leverage as a result of leveraged buyouts and corporate restructurings.

Since there has been a prolonged deterioration in overall corporate credit quality. We find negative correlation between changes in interest rates and default rates, with the correlations between changes in short rates and default rates being significantly negative.

This result generally was consistent with findings on the relationship between changes in credit spread and changes in interest rates documented in a few papers. Our empirical findings have a number of important implications in practice.

The relationship between default risk and interest rates: An empirical study

The results suggest that the interest rate and default risk dynamics are more complicated than previously reported. From the perspective of comprehensive risk modeling, this suggests that it is quite challenging, perhaps impossible, to specify a theoretical model that fully describes both the interest rate and default processes in a correlated manner with a single correlation parameter. This also suggests that once an accurate credit risk measure such as EDF is properly incorporated, interest rates and default risk become conditionally uncorrelated in the joint model, leading to a significant 1 See Longstaff and SchwartzDuffeeand Collin-Dufresne et al.

From the perspective of managing both interest rate and default risk, our results suggest that risk managers should be paying close attention to these dynamics, especially when hedging is involved. This paper is organized in the following way.

Most studies focus on the relationship between credit spreads and various interest rate variables. As far as we know, Fridson et al. They argue that interest rate level is the basis of cost of capital. When the interest rate is high, the firm must generate higher rate of return in order to survive. If the cost of capital is higher than the rate of return, the firm would run into financial insolvency or bankruptcy.

This indicates that there is a positive relationship between default rate and real interest rates. Longstaff and Schwartz develop a simple approach to valuing risky corporate debt that incorporates both default and interest rate risk, and test its empirical implications. For example, a basis point increase in the year Treasury yield reduces Baa-rated Utility industry credit spreads by Duffee studies the correlation between the changes in 3-month Treasury bill yield, the changes in term structure slope defined as the difference between year and 3-month Treasury bond yieldsand the changes in yield spread of corporate bond with data from — The changes in yield spread are constructed monthly from non-callable bonds rated from Aaa to Baa, maturities ranging from 2 to 30 years.

He finds that an increase in T-bill yield corresponds with a decline in yield spreads for each combination of maturity and credit rating. The relationship is stronger for longer- maturity and for lower quality bonds. The relation between yield spreads and slope is generally negative, insignificant for high quality bonds and significant for low quality bonds.

Callable bonds show stronger negative correlations than non-callable bonds. The regressions are performed for bonds in each unique combination of maturity and rating category. They find significant negative correlations in the changes in interest rates, insignificant negative correlations in the convexity, and insignificant negative correlations in the change in slope for bonds with longer maturities, and insignificant positive correlations in the change in slope for bonds with shorter maturities.

The changes in credit spread are selected from Lehman Brothers bond indexes, or constructed from individual non- callable bonds rated from AA to BBB and maturities ranging from intermediate to long-term.

They find the relation 6 between credit spreads and interest rates level and slope differ based on the maturity, credit ratings, and the sign of the relation changes based upon the time frame.

In aggregate, the results suggest that Treasury yields are positively related to credit spreads in the long run, but negatively related in the short run.

  • Default Risk

The relation between credit spreads and the slope of Treasury term structure depends on credit quality, maturity, and time frame. As the spread rises on less actively traded bonds, so does liquidity risk. High-yield bonds can sometimes be less liquid than investment-grade bonds, depending on the issuer and the market conditions at any given time.

Economic risk describes the vulnerability of a bond to downturns in the economy. For example, inwhen the U. GDP went into a decline that lasted three consecutive quarters, the principal value and the total return of high-yield bonds declined significantly.

Virtually all types of high-yield bonds are vulnerable to economic risk. In recessions, high-yield bonds typically lose more principal value than investment-grade bonds. If investors grow anxious about holding low-quality bonds, they may trade them for the highest-quality debt, such as U.
