Credit Spread

Yield difference between a corporate bond and a government bond of similar maturity.

A credit spread is the difference in yield between two debt securities of the same maturity but different credit qualities. Most commonly, it refers to the extra yield a corporate bond pays over a risk-free government bond, such as a U.S. Treasury. This spread compensates investors for taking on default risk, which is the risk that the corporate borrower will fail to make its scheduled interest or principal payments. To observe a credit spread, investors compare the yield to maturity of a corporate bond to the yield of a government bond with a matching maturity date. Credit spreads fluctuate constantly based on market conditions, economic data, and the specific financial health of the issuing company. Credit rating agencies also influence these spreads by assigning ratings that reflect a borrower's creditworthiness. Investors monitor credit spreads as a barometer for both individual corporate health and broader economic sentiment. Narrowing (or tightening) spreads suggest that investors are confident in the economy and the borrower's ability to repay, leading them to demand less premium for taking on risk. Conversely, widening spreads indicate growing economic anxiety or deteriorating corporate finances, as investors demand higher yields to justify holding riskier debt.

If a 10-year corporate bond issued by Company A is trading at a yield of 6.5%, and a 10-year U.S. Treasury bond is trading at a yield of 4.2%, the credit spread is calculated as 6.5% - 4.2% = 2.3% (or 230 basis points).
