What is I-spread and Z-spread?

While G-spread and I-spread just measure the difference between the static yield to maturity of the bond and the Treasury yields or benchmark rate, Z-spread determines the difference in yields with reference to whole term structure of interest rates.

Is higher option-adjusted spread better?

An investor would use the option-adjusted spread to compare one bond with an embedded option to another with an embedded option. The one with the higher range will have a lower price.

How option-adjusted spread is calculated?

If the market price of the security is $ 79.2, then the corresponding OAS is 75 bps. If the market price of the security is $ 75, then the option-adjusted spread is computed using linear interpolation. It approximates the value of a given function at a given set of discrete points.

What is the high yield OAS spread?

One measure that investors use to assess the level of risk inherent in a high-yield bond is the high-yield bond spread. The high-yield bond spread is the difference between the yield for low-grade bonds and the yield for stable high-grade bonds or government bonds of similar maturity.

Can OAS spread negative?

OAS values can be positive or negative. A negative OAS for a callable bond signifies that, after taking the redemption option into account, the bond has a lower expected return than the risk-free option. All things being equal, an investor would prefer a higher OAS over a lower OAS.

Why does OAS decrease as volatility increases?

The option-adjusted spread is the single spread added uniformly to the one-period forward rates on the tree to produce a value or price for a bond. OAS is sensitive to interest rate volatility: The higher the volatility, the lower the OAS for a callable bond.

Is OAS a credit spread?

Sometimes investors also use a derivative of the Z-spread to measure the credit risk premium, the OAS-spread (option adjusted spread). The OAS-spread equals the Z-spread plus or minus the value of embedded bond options, i.e. make- whole call (MWC) (Chart 1).
