Calculate zero rate swap
We use the bootstrapping bonds method to derive the zero curve from the par term structure. The step by step procedure employed in given below:. Given the default par term structure above we calculate the cash flows for coupon bearing instruments for each tenor. We assume that the par value for each instrument is The assumption of par for the instruments means that the coupon rate is equal to the par rate.

A zero coupon swap is an exchange of cash flows in which the stream of floating interest-rate payments is made periodically, as it would be in a plain vanilla swap , but where the stream of fixed-rate payments is made as one lump-sum payment at the time when the swap reaches maturity, instead of periodically over the life of the swap. A zero coupon swap is a derivative contract entered into by two parties. One party makes floating payments which changes according to the future publication of the interest rate index e.
The other party makes payments to the other based on an agreed fixed interest rate. The fixed interest rate is tied to a zero coupon bond , or a bond that pays no interest for the life of the bond, but is expected to make one single payment at maturity.
In effect, the amount of the fixed-rate payment is based on the swap's zero coupon rate. The bondholder on the end of the fixed leg of a zero coupon swap is responsible for making one payment at maturity, while the party on the end of the floating leg must make periodic payments over the contract life of the swap. However, zero coupon swaps can be structured so that both floating and fixed rate payments are paid as a lump sum.
The counterparty that does not receive payment until the end of the agreement incurs a greater credit risk than it would with a plain vanilla swap in which both fixed and floating interest rate payments are agreed to be paid on certain dates over time. Valuing a zero coupon swap involves determining the present value of the cash flows using a spot rate or zero coupon rate. The spot rate is an interest rate that applies to a discount bond that pays no coupon and produces just one cash flow at maturity date.
The present value of each fixed and floating leg will be determined separately and summed together. Since the fixed rate payments are known ahead of time, calculating the present value of this leg is straightforward. To derive the present value of cash flows from the floating rate leg, the implied forward rate must be calculated first.
The forward rates are usually implied from spot rates. The spot rates are derived from a spot curve which is built from bootstrapping , a technique that shows a sequence of spot or zero-coupon rates that are consistent with the prices and yields on coupon bonds.
Variations of the zero coupon swap exist to meet different investment needs. A reverse zero coupon swap pays the fixed lump-sum payment upfront when the contract is initiated, reducing credit risk for the pay-floating party.
Under an exchangeable zero coupon swap , the party scheduled to receive a fixed sum at the maturity date can use an embedded option to turn the lump-sum payment into a series of fixed payments. The floating payer will benefit from this structure if volatility declines and interest rates are relatively stable to declining. It is also possible for the floating-rate payments to be paid as a lump sum in a zero-coupon swap under an exchangeable zero coupon swap.

Key Takeaways A zero coupon swap is an exchange of fixed-for-floating cash flows, but where the fixed side of the swap is paid as one lump sum when the contract reaches maturity.
The variable side of the swap makes regular payments, as they would in a plain-vanilla swap. Because the fixed leg is paid as a lump sum, valuing a zero coupon swap involves determining the present value of those cash flows using a zero coupon bond's implied interest rate. Compare Accounts.

Related Terms Plain Vanilla Swap A plain vanilla swap is the most basic type of forward claim that is traded in the over-the-counter market between two private parties.
Interest Rate Derivative Definition An interest-rate derivative is a broad term for a derivative contract, such as a futures, option, or swap, that has an interest rate as its underlying asset.
Commodity Swap Definition A commodity swap is a contract where two sides of the deal agree to exchange cash flows, which are dependent on the price of an underlying commodity.
Interest Rate Swap Definition An interest rate swap is a forward contract in which one stream of future interest payments is exchanged for another based on a specified principal amount. Zero Coupon Inflation Swap Definition A zero coupon inflation swap is a derivative where a fixed rate payment on a notional amount is exchanged for a payment at the rate of inflation. Floating Price Definition The floating price is a leg of a swap contract that depends on a variable, including an interest rate, currency exchange rate or price of an asset.

If we know the par yield, we can calculate both the zero coupon yield and the forward yield for the same maturities and risk class. Example 1: Converting from par rates to zero coupon rates. The no-arbitrage relationship between par rates and zero coupon rates is summarised in the formula:. This means that 2.
This is the fourth in a series of articles that will go from the basics about interest rate swaps, to how to value them and how to build a zero curve.
In finance , bootstrapping is a method for constructing a zero-coupon fixed-income yield curve from the prices of a set of coupon-bearing products, e. A bootstrapped curve , correspondingly, is one where the prices of the instruments used as an input to the curve, will be an exact output , when these same instruments are valued using this curve. Here, the term structure of spot returns is recovered from the bond yields by solving for them recursively, by forward substitution : this iterative process is called the bootstrap method.

Deriving zero rates and forward rates using the bootstrapping process is a standard first step for many valuation, pricing and risk models. Understanding how to build the bootstrapping model in EXCEL is therefore an essential corner stone to building more complex models that depend on its results. In this post we will walk you through the process of building a zero curve bootstrapping model in EXCEL. It is usually steps 3 to 6, the iterative process of the model that is a cause of confusion among students when constructing the bootstrapping model in EXCEL. We would need a par term structure that has rates for each quarterly tenor from 0.
Bootstrapping bonds to derive the zero curve
Vanilla swaps are the most common type of interest rate swaps. These convert floating interest payments into fixed interest payments and vice versa. Treasury Bonds. Plain vanilla swaps , like most derivative instruments, have zero value at initiation. Like all derivatives, swaps are zero-sum instruments, so any positive value increase to one party is a loss to the other. For this statement to be true, the values of the cash flow streams that the swap parties are going to exchange should be equal. This concept is illustrated with a hypothetical example in which the value of the fixed leg and floating leg of the swap will be V fix and V fl respectively. Thus, at initiation:. Notional amounts are not exchanged in interest rate swaps because these amounts are equal and it does not make sense to exchange them. If it is assumed that parties also decide to exchange the notional amount at the end of the period, the process will be similar to an exchange of a fixed rate bond to a floating rate bond with the same notional amount.
