Understanding Yield Spread: Definition, How It Works, and Types of Spreads

When it comes to understanding the dynamics and intricacies of the financial world, it’s essential to familiarize yourself with various financial terms. One such term that you may have come across is the yield spread. But what exactly is a yield spread? How does it work? And what are the different types of spreads? In this blog post, we will dive into the world of yield spreads and shed light on these questions.

Key Takeaways:

  • A yield spread refers to the difference between the yields on two different financial instruments or investment options.
  • It is commonly used to assess the risk and return associated with specific investments or to compare different options in the financial market.

Defining Yield Spread

A yield spread, in finance, refers to the difference between the yields on two different types of investments or financial instruments. It serves as an indicator of the risk and return associated with these investments. By calculating the yield spread, investors can determine whether an investment is offering a higher or lower return compared to another option.

The yield spread is typically expressed in basis points, which is equal to one-hundredth of a percentage point. It provides valuable information to investors, enabling them to make informed decisions based on the potential risks and rewards of different investment opportunities.

How Does Yield Spread Work?

Yield spreads work by comparing the yields of two different investments or financial instruments. The wider the spread, the greater the difference in yields between the two options. A wider spread usually indicates a higher level of risk associated with an investment, while a narrower spread suggests a lower level of risk.

Investors can use yield spreads to assess the creditworthiness of a bond issuer. For example, if a corporate bond has a higher yield spread compared to a government bond with a similar maturity, it suggests that the market perceives the corporate bond to carry higher risk due to factors like the company’s financial health or credit rating.

Yield spreads are also commonly used in mortgage markets to determine interest rates. Lenders often take into account the yield spread on mortgage-backed securities to set interest rates for home loans. For instance, if the yield spread for mortgage-backed securities widens due to market conditions, it may lead to an increase in mortgage interest rates for borrowers.

Types of Yield Spreads

There are several different types of yield spreads, each serving a specific purpose in the financial market. Here are a few key types:

  1. Option-Adjusted Spread (OAS): This spread measures the yield differential between a security and a risk-free benchmark. It takes into account factors such as prepayment risk for mortgage-backed securities or call options for bonds.
  2. Credit Spread: The credit spread represents the additional yield compensation investors receive for taking on credit risk when investing in corporate bonds or other debt instruments. It measures the difference in yields between a riskier investment and a comparable risk-free investment.
  3. Intermarket Spread: Intermarket spreads compare the yields on two securities from different markets, such as comparing the yield on a U.S. government bond to that of a foreign government bond. It helps investors analyze the relative attractiveness of investments across markets.

Understanding these types of yield spreads empowers investors to make well-informed decisions by assessing the risk and potential return of various investment opportunities.


Yield spreads provide valuable insights into the risk and return associated with investment options. By comparing the yields of different securities or financial instruments, investors can gauge the attractiveness of various investments. Different types of yield spreads, such as option-adjusted spreads, credit spreads, and intermarket spreads, help investors in making informed decisions based on the specific risks and rewards of different financial instruments.

So, the next time you come across the term “yield spread,” you’ll have a better understanding of what it means and how it impacts the financial market.
