A zero-coupon yield is the actual or theoretical yield earned on an instrument where there are no cashflows other than at the start and at maturity. The spot yield curve shows zero-coupon yields against time to maturity. Bootstrapping is a process of building up a theoretical spot yield curve by calculating zero-coupon yields for successively longer maturities from those for shorter maturities. A zero-coupon instrument is one which pays no coupon. For example, a company might issue a 5-year bond with a face value of but no coupon. Clearly an investor would not pay for this; he would pay considerably less to allow for the fact that

## Bond Pricing

The spot rate treasury curve is a yield curve constructed using Treasury spot rates rather than yields. The spot rate Treasury curve can be used as a benchmark for pricing bonds. This type of rate curve can be built from on-the-run treasuries, off-the-run treasuries, or a combination of both. Alternatively, the Treasury curve can be calculated by using Treasury coupon strips.

To reflect market expectations of changing interest rates, bonds may be priced based on Treasury spot rates rather than Treasury yields. When spot rates are derived and plotted on a graph, the resulting curve is the spot rate Treasury curve. Spot rates are prices quoted for immediate bond settlements, so pricing based on spot rates takes into account anticipated changes to market conditions. Theoretically, the spot rate or yield for a particular term for maturity is the same as the yield on a zero-coupon bond with the same maturity.

The spot rate Treasury curve provides the yield to maturity YTM for zero-coupon bonds that is used to discount a single cash flow at maturity. Thus, to determine the price of a coupon-paying bond, the YTM is used to discount the first coupon payment at the spot rate for its maturity, and the second coupon payment at the spot rate for its maturity, and so on.

Because many bonds typically have multiple cash flows coupon payments at different points during the duration of the bond, it is not theoretically correct to use just one interest rate to discount all of the cash flow. Therefore, in order to make a sound bond valuation, it is good practice to match up and discount each coupon payment with the corresponding Treasury spot rate for pricing the present value of each cash flow. When the spot rates are plotted against the maturities, we get the spot rate or the zero curve.

Using the bootstrap method , the number of periods will be designated as 0. However, this is not necessarily the price at which the bond will ultimately be sold. Because the spot rates used to price bonds reflect rates that are from default-free Treasuries, the corporate bond s price will need to be further discounted to account for its increased risk compared to Treasury bonds.

It is important to note that the spot rate Treasury curve is not an accurate indicator of average market yields because most bonds are not zero-coupon.

The present value for each respective cash flow will be: Related Terms Par Yield Curve A par yield curve is a graphical representation of the yields of hypothetical Treasury securities with prices at par.

Static Spread The static spread is the constant yield spread above the spot rate Treasury curve which equates the price of the bond to the present value of its cash flows. Zero-Volatility Spread Z-spread The Zero-volatility spread is the constant spread that will make the price of a security equal to the present value of its cash flows.

Par and zero coupon curves are two common ways of specifying a yield curve. Par coupon yields are quite often encountered in economic analysis of bond yields, such as the Fed H. Zero coupon curves are a building block for interest rate pricers, but they are less commonly encountered away from such uses. In order to avoid being dragged down with the details of fixed income pricing conventions, this article uses a basic interest rate convention, and only looks at maturities, which are an integer number of years.

Unlike nominal bonds, there are relatively few inflation-indexed bonds on issue for the majority of our sample period, which makes estimating a zero-coupon real yield curve difficult. In particular, between and there are between two and three inflation-indexed bonds with residual maturity between 1 and 15 years outstanding at any one time, while from there are four to five such bonds outstanding at any one time. This low number makes fitting a flexible yield curve problematic, as arbitrary choices in yield curve modelling can have a non-negligible impact on the estimated curve shape. To alleviate this problem we choose a particularly simple and transparent yield curve fitting method:

### Yield curves

The rate of return on an investment today, for a single cashflow at the final maturity of the instrument. No intermediate interest is payable or receivable. There are no interest coupons, hence the name zero coupon . The zero coupon yield is equal to the current market rate of return on investments in zero coupon bonds of the same maturity. Cash flows from 3-period zero coupon instrument. If we know the zero coupon yield, we can calculate both the forward yield and the par yield for the same maturities and risk class. The conversion process and calculation stems from the no-arbitrage relationship between the related yield curves. This is illustrated on the page Converting from zero coupon rates.

### Yield curve

In finance , the yield curve is a curve showing several yields or interest rates across different contract lengths 2 month, 2 year, 20 year, etc. The curve shows the relation between the level of the interest rate or cost of borrowing and the time to maturity , known as the "term", of the debt for a given borrower in a given currency. Treasury securities for various maturities are closely watched by many traders, and are commonly plotted on a graph such as the one on the right which is informally called "the yield curve". The shape of the yield curve indicates the cumulative priorities of all lenders relative to a particular borrower such as the US Treasury or the Treasury of Japan , or the priorities of a single lender relative to all possible borrowers. With other factors held equal, lenders will prefer to have funds at their disposal, rather than at the disposal of a third party. The interest rate is the "price" paid to convince them to lend. As the term of the loan increases, lenders demand an increase in the interest received.

Our organization is about to expand its operations into the European Union EU. To do that we will have to raise several hundred million dollars of collateral to back employees, customers, and our supply chain in the EU. Negative interest rates abound in the markets as political events and central bankers vie for control of the euro and its relationship to major currencies. Our task is to help the Chief Financial Officer understand how the term structure of interest rates might change and thus impact the amount and pricing of the collateral our organization is about to raise. Higher yields mean also that you would have to price the bond at a higher coupon rate. This means more income is paid out to lenders and bondholders than to management, staff, and shareholders. The consequence is cash flow volatility. Our objective is to conceive a model of bond prices that reflects the underlying dynamics of the term structure of interest rates. Such a model requires us to formulate forward rates of return on bonds of various maturities, and average these rates across the time to maturity in a yield calculation.

Financial market analysis of fixed income markets typically rely on the availability of yield curve data. That is, at the outset, yield observations for the relevant market segments are directly observable at the desired maturities.

By Amruth Sundarkumar 4 Comments. Fixed Income Tutorials. They are:. The price of a bond is essentially a function of the above. Combining them all, for a bond paying coupons annually and YTM annually compounded we get:. In general about the structure of the formula, it should make sense unless you are an earth shattering thinker. Try it out with your own numbers applying the above formula and determine the price. In general, bonds are issued at par and redeemed at par. Although practically done very little, bonds can be issued at a discount or a premium or redeemed at a discount or premium. Let us look at Bond Pricing calculation in Excel. Assume ABC Inc. Since it is a par bond, the YTM and coupon rate will be the same. It rather gets a return equal to the YTM of the bond. We can use different methods for Bond Pricing.

A zero curve is a special type of yield curve that maps interest rates on zero-coupon bonds to different maturities across time. Zero-coupon bonds have a single payment at maturity, so these curves enable you to price arbitrary cash flows, fixed-income instruments, and derivatives. Another type of interest rate curve, the forward curve, is constructed using the forward rates derived from this curve. Zero-coupon bonds are available for a limited number of maturities, so you typically construct zero curves with a combination of bootstrapping and interpolation techniques in order to build a continuous curve. Once you construct these curves, you can then use them to derive other curves such as the forward curve and to price financial instruments.

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. Here, the term structure of spot returns is recovered from the bond yields by solving for them recursively, by forward substitution: The usefulness of bootstrapping is that using only a few carefully selected zero-coupon products, it becomes possible to derive par swap rates forward and spot for all maturities given the solved curve. We then use these rates to calculate the 1. Then, say, e. We solve the 1. As stated above, the selection of the input securities is important, given that there is a general lack of data points in a yield curve there are only a fixed number of products in the market. More importantly, because the input securities have varying coupon frequencies, the selection of the input securities is critical. It makes sense to construct a curve of zero-coupon instruments from which one can price any yield, whether forward or spot, without the need of more external information. The general methodology is as follows:
