In developing countries like India where the government is among the biggest investors in the economy, bond yields can be a useful parameter in assessing economic health. Photo Credit: The recent furore over the magnitude of frauds at public sector banks has added to the pile of non-performing assets the banking sector is saddled with. Big-ticket welfare programmes like the National Health Protection Scheme — dubbed Modicare — and the ambitious plan to double farmers incomes by increasing the minimum support price to 1. But if the system is not flush with funds for these schemes, the government has to go into debt; and that has a bearing on the economy. Economists keep an eye out for the numbers coming out of the bond market.

Remember that interest rates and bond prices move in opposite directions: When interest rates rise, bond prices fall, and vice versa. Zero-Coupon Bond. Duration is equal to its time to maturity. Plain Vanilla Bond. Duration will always be less than its time to maturity. In general, the higher the duration, the more a bond s price will drop as interest rates rise and the greater the interest rate risk. A commonly used method to calculate duration is the Macaulay duration , developed by Frederick Macaulay in Because the formula is complicated and time consuming, most investors use calculators to do the math.

To determine duration, enter the par value, settlement date, maturity date, annual coupon rate and yield, and select the payment frequency. The calculator shows that the Macaulay duration of the bond equals 4. In general, bonds with a long duration have a higher price fluctuation than bonds with a short duration.

As a result, if you want to invest in a bond with minimal interest rate risk, a good choice would be a bond with high coupon payments and a short term to maturity. As a result, bonds with poor credit ratings typically have lower price volatility than bonds with excellent ratings. These factors work for and against each other, and affect the degree to which bond prices change in response to prevailing interest rate changes, as demonstrated in the following chart:. Advanced Bond Concepts: Duration By Jean Folger Share.

Introduction Advanced Bond Concepts: Bond Pricing Advanced Bond Concepts: Duration Advanced Bond Concepts: Convexity Advanced Bond Concepts: For each of the two basic types of bonds the duration is the following: Time to maturity. The longer the maturity , the higher the duration, and the greater the interest rate risk. A bond that matures faster — say, in one year — would repay its true cost faster than a bond that matures in 10 years. Consequently, the shorter-maturity bond would have a lower duration and less risk.

Coupon rate. If we have two bonds that are identical with the exception on their coupon rates, the bond with the higher coupon rate will pay back its original costs faster than the bond with a lower yield. The higher the coupon rate, the lower the duration, and the lower the interest rate risk. Macaulay Duration A commonly used method to calculate duration is the Macaulay duration , developed by Frederick Macaulay in There are other ways to calculate duration: Modified duration.

A modified version of the Macaulay model that accounts for changing interest rates. Effective duration. A method that uses binomial trees to calculate the option-adjusted spread. Key-rate duration. These include the three-month, and one, two, three, five, seven, 10, 15, 20, 25 and year portions of the curve.

High Duration In general, bonds with a long duration have a higher price fluctuation than bonds with a short duration. These factors work for and against each other, and affect the degree to which bond prices change in response to prevailing interest rate changes, as demonstrated in the following chart: Duration principles to remember: Changes in the value of a bond are inversely related to changes in the rate of return.

Long-term bonds have greater interest rate risk than short-term bonds. As the bond coupon increases, its duration decreases and the bond becomes less sensitive to interest rate changes. As interest rates increase, duration decreases and the bond becomes less sensitive to future rate changes. Related Articles. Bonds and bond funds are fixed-income investments, but their duration, combined with changes to interest rates, can lead to price fluctuations.

The interest rate increase by the Fed was one of the most widely anticipated in history. Here s what it means for bond mutual funds. Duration tells investors the length of time it will take a bond s cash flows to repay the investor the price he or she paid for the bond. A bond s duration is stated as a number of years and Investors need to understand the five mistakes involving interest rate risk, credit risk, complex bonds, markups and inflation to avoid in the bond market. Learn about how investors should evaluate bond performance.

See how the maturity of a bond can impact its exposure to interest rate risk. Investors base investing decisions and strategies on yield to maturity more so than coupon rates. Learn about various ways that you can adjust a fixed income investment portfolio to mitigate the potential negative effect of rising interest rates.

So, what now? With the year U. Treasury UST bond back under 2. Perhaps, but first we need to do some digging into that 2. Looking at the UST yield curve, we see only low returns. The problem is yield curve math is especially yield-deflating in this Fed-influenced market.

### Bond yield curve holds predictive powers

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.

### What rising bond yields tell us about the economy

Yield curve, treasury market, inflation compensation, risk premia. For over ten years, the U. Treasury has issued index-linked debt. Federal Reserve Board staff have fitted a yield curve to these indexed securities at the daily frequency from the start of to the present. This paper describes the methodology that is used and makes the estimates public. Comparison with the corresponding nominal yield curve allows measures of inflation compensation or breakeven inflation rates to be computed. We discuss the interpretation of inflation compensation and its relationship to inflation expectations and uncertainty, offering some empirical evidence that these measures are affected by an inflation risk premium that varies considerably at high frequency. In addition, we also find evidence that inflation compensation was held down in the early years of the sample by a premium associated with the illiquidity of TIPS at the time. We hope that the TIPS yield curve and inflation compensation data, which are posted here and will be updated periodically, will provide a useful tool to applied economists.

If you invest in equities , you should keep an eye on the bond market. If you invest in real estate , you should keep an eye on the bond market. If you invest in bonds or bond ETFs , you should definitely keep an eye on the bond market! The bond market is a great predictor of future economic activity and future levels of inflation, both of which directly affect the price of everything from stocks and real estate to household items. In this article, we ll discuss short-term versus long-term interest rates, the yield curve and how to use the study of yields to your advantage in making a broad range of investment decisions.

I m currently working on roll down calculations for the Treasury curve 3-month roll, 6-month roll, etc.. One of the senior guys I just started out of college asked me to adjust for the coupon effects for some of the long dated bonds. I understand that higher coupon bonds have lower yields than other bonds with the same maturity. However, I am not sure the proper way to adjust for the coupon effects. To calculate rolldown that accounts for the coupon effect requires a fitted curve. Assuming such a curve is available, then the following procedure is usually followed:. First, calculate the z-spread of the bond in question relative to the fitted curve:
