Typically, investors and analysts use this financial metric to calculate the yield differences risk-free government bonds and corporate bonds with the same maturity dates. Since are comparatively riskier than government bonds, they require higher yields. Thus, the credit spread strategy helps in measuring the extra return that corporate bondholders will expect to get as compensation for the higher risk level.

Let’s assume a firm wants to borrow funds from the market over 15 years. However, the firm is not sure how the market will evaluate the company’s risks, i.e., lack of clarity on what the credit spread for bonds will be. Borrowing costs can be severely impacted if the yield spread is high.

The management must consider the following factors before a decision on debt issuance:

  • Liquidity
  • Taxes
  • Accounting Transparency
  • Defaulting history, if any
  • Asset Liquidity

All the above-mentioned factors must be carefully studied as it can impact the widening of spreads. Any improvements in company analysis can result in a narrowing of spreads.

Let us understand the concept of credit spread management with the help of some examples.

Example #1

If there is a lot of uncertainty in the market, investors tend to park their funds in safe havens like US Treasuries causing the yield to fall since there is a surge of funds. On the other hand, the yields of Corporate bonds will increase due to an increased level of uncertainty. Thus, even though Treasury yields are falling in this instance, the spread is widening.

Example #2

If a five-year Treasury bond is trading at a yield of 5% and another five years Corporate Bond is trading at 6.5%, then the spread over the treasury will be 150 basis points (1.5%).

The two simple examples given above clarify the concept.

Credit Spread’s Relation To Credit Risk

There is a common misconception that credit spread for bonds is the single most significant factor in determining the credit riskCredit RiskCredit risk is the probability of a loss owing to the borrower's failure to repay the loan or meet debt obligations. It refers to the possibility that the lender may not receive the debt's principal and an interest component, resulting in interrupted cash flow and increased cost of collection.read more of bonds. However, multiple other factors determine the ‘spread premium’ of bonds over other treasuries.

For e.g., bonds with favorable tax implications like Municipal bonds can trade at a yield lower than US treasuries. This is not due to the market considering them less risky, but due to the general perception of Municipal bondsMunicipal BondsA municipal bond is a debt security issued by a national, state, or local authority to finance capital expenditures on public projects related to the development and maintenance of infrastructures such as roads, railways, schools, hospitals, and airports.read more considered almost as safe as treasuries and having a big tax advantage.

Credit Spread Vs Debit Spread

The above are ttwo different strategies that are frequently used in option trading. However, there are some differences between them, as follows.

  • The credit spread in options is a strategy in which the trader gets a net premium on entering into the option position but in the latter the trader pays a net premium to enter into the option position.
  • In case of the former, the option that is sold has a higher premium than the option that is bought whereas for the latter, the option bought has a higher premium than the option that is sold.
  • For the former, the maximum profit is limited to the initial premium received and maximum loss is the difference between the strike price and premium. But the maximum loss for the latter is limited to the premium paid.
  • The former helps in managing the risk because the profit is limited, whereas the latter can manage risk only if the trader is aware that the price will process in a particular direction.
  • Credit spread strategy is used in any trading environment with higher volatility, but debit spread requires lower volatile environment.
  • The concept of time decay work for the investors who go for credit spread but against the investors who go for debit spread.

Thus, the above are some essential differences between the two concepts.
