Swap Valua[on
Vswap = B fix − B float
Vswap = B float − B fixed
If you are a fixed receiver
If you are a floating receiver
• A bond value is the sum of discounted cash flows • A swap value is the difference in the sum of discounted cash flows • We use term structure of interest rates to calculate the value

Interest Rate Swap Valua[on Example I
• Receive 10% fixed and pay 1 year LIBOR + 1% for next 3 years • Equivalent to switching a floater with fixed coupon rate bond • $100 million principal – Swap no[onal value • Current term structure: Year

Interest Rate Swap Example III
• Suppose we can use LIBOR spot rates to discount the cash flows of the swap • Then the swap value is the discounted value of the cash flows • Typically, two par[es set the ini[al value of the swap as zero-‐value transac[on Year
