DEFINITION of 'Zero-Volatility Spread-Z-spread'. The constant spread that will make the price of a security equal to the present value of its cash flows when added to the yield at each point on the spot rate Treasury curve where a cash flow is received.he Z-spread is also known as a static spread.
The asset swap spread is the spread that equates the difference between the present value of the bondâs cashflows, calculated using the swap zero rates, and the market price of the bond. This spread is a function of the bondâs market price and yield, its cashflows and the implied zero-coupon interest rates.he zero-coupon curve used in the calculation is derived from the interest-rate swap curve. Put simply, the Z-spread is the basis point spread that would need to be added to the implied spot yield curve such that the discounted cash flows of the a bond are equal to its present value (its current market price).
