In finance, high bond duration is primarily caused by long times to maturity and low coupon rates, making the bond price more sensitive to interest rate changes. Longer terms, such as 10-30 years, increase risk, while lower coupons mean less cash flow is received early, extending the time to recover the investment.
The duration of a bond is affected by its coupon rate, yield, and remaining time to maturity. The duration of a bond will be higher the lower its coupon. Duration will be higher the lower its yield. Duration will also be higher the longer its maturity.
Generally speaking, duration tells us the degree of interest rate risk of a particular income investment. The higher the duration, the more an investment's price will drop as interest rates increase (or increase as interest rates decrease).
Duration is a measurement of a bond's interest rate risk that considers a bond's maturity, yield, coupon and call features. These many factors are calculated into one number that measures how sensitive a bond's value may be to interest rate changes.
Duration is a measure of interest rate risk. High duration bond funds will have higher risk, higher volatility, and higher max drawdowns.
Bonds with higher durations carry more risk and price volatility. Duration indicates the years it takes to receive a bond's true cost, weighing in the present value of all future coupon and principal payments.
How Duration Works in Investing. Duration is a measure of the sensitivity of the price of a bond or other debt instrument to a change in interest rates. In general, the higher the duration, the more a bond's price will drop as interest rates rise. This also indicates a higher level of interest rate risk.
Interest rates directly affect bond prices. When interest rates rise, bond prices fall; when rates drop, bond prices rise. This relationship, known as interest rate risk, means that if you sell a bond before it matures, you may receive more or less than its face value depending on current rates.
Duration Details
Bond duration is a measure of the degree to which a bond investment is likely to change in value if interest rates were to rise or fall. The higher the number, the more sensitive your bond investment will be to changes in interest rates.

There are three types of bond durations namely, Macaulay duration, modified duration and effective duration. A Macaulay duration represents the weighted average time before a bond's cash flows are fully paid and provides an effective way of measuring the time until an investor will get their money back.
So how does duration fit in? Investors holding a high duration bond need to wait longer for the bond's value to be repaid. But over a longer timeline, it is more likely that interest rates will rise, which means there is a higher likelihood that the bond's value will decline.
Duration risk, also referred to as interest rate risk, is the risk that changes in interest (borrowing) rates may reduce or increase the market value of a fixed-income investment. The interest rate is the cost of borrowing, while bond prices reflect the market value of bonds.
Duration is a way of measuring the interest rate risk of an individual or portfolio of fixed income securities. Pure, or Macaulay duration, is calculated by discounting all cash flows of a bond using the proper interest rate and then time weighting each of the cash flows.
If interest rates fall, longer maturities tend to outperform. But even if yields remained broadly unchanged, just a small increase in duration could provide an attractive return over the course of a year.
By buying or selling futures, it is possible to increase or decrease the total modified duration of the portfolio. An investor forecasting a rise in interest rates may want to reduce the duration of his portfolio.
As a general rule, for every 1% increase or decrease in interest rates, a bond's price will change approximately 1% in the opposite direction for every year of duration. For example, if a bond has a duration of 5 years, and interest rates increase by 1%, the bond's price will decline by approximately 5%.
