Effective duration is a duration calculation for bonds that have embedded options.The impact on cash flows as interest rates change is measured by effective duration. Effective duration calculates the expected price decline of a bond when interest rates rise by 1%.

What is effective duration vs modified duration?
While Effective Duration is a more complete measure of a bond’s sensitivity to interest rate movements versus the Macauley or Modified Duration measures, it still falls short because it is a linear approximation for small changes in yield; that is, it assumes that duration stays the same along the yield curve.
What is effective duration CFA?
The effective duration is defined as the sensitivity of the price of a bond against a change in a benchmark yield curve.
What is the unit of effective duration?
Effective duration measures the change in price of a bond to a 1% or a 100 basis point change in the yield of the bond across all maturities and therefore a parallel shift of the yield curve by 1% indicating the amount of interest rate risk the bondholder needs to bear by holding the given bond in his investment
Is effective duration the same as Macaulay duration?
3. Effective Duration. Effective duration is a measure of the duration for bonds with embedded options (e.g., callable bonds). Unlike the modified duration and Macaulay duration, effective duration considers fluctuations in the bond’s price movements relative to the changes in the bond’s yield to maturity (YTM).
What is effective maturity?
The effective maturity of a bond refers to the effective yield or effective rate of interest of the bond at the culmination of its tenure. (“Tenure” is the length of time until the bond matures.) Calculate the amount of interest paid yearly by the bond.
Can effective duration be negative?
Many bond funds–in particular those holding lots of short-term securities–have average effective durations of 1 year or less (and floating-rate funds often have durations very close to zero). But a handful of funds have effective durations that venture into negative territory.
Is effective duration expressed in years?
Duration is measured in years. Generally, the higher the duration of a bond or a bond fund (meaning the longer you need to wait for the payment of coupons and return of principal), the more its price will drop as interest rates rise.
What are the three types of duration?
Duration – Definition, Top 3 Types (Macaulay, Modified, Effective Duration)
What are the types of duration?
There are two types of duration: Macaulay duration and modified duration.
Why is duration shorter than maturity?
Duration is defined as the average time it takes to receive all the cash flows of a bond, weighted by the present value of each of the cash flows.The duration of any bond that pays a coupon will be less than its maturity, because some amount of coupon payments will be received before the maturity date.
How do you calculate effective maturity date?
For example, assume a bond issued in 2010 has a maturity date of 20 years.
The average effective maturity of the portfolio can be calculated as:
- Average effective maturity = (30 x 0.15) + (20 x 0.25) + (15 x 0.20) + (11 x 0.10) + (3 x 0.3)
- = 4.5 + 5 + 3 + 1.1 + 0.9.
- = 14.5 years.
What is average duration?
Average Duration. Duration is a time measure of a bond’s interest-rate sensitivity, based on the weighted average of the time periods over which a bond’s cash flows accrue to the bondholder. Time periods are weighted by multiplying by the present value of its cash flow divided by the bond’s price.
What does a negative effective duration mean?
If you short sell a bond, the other person’s gain is your loss. So if he has a duration of 2.5 years, if interest rates fall, the price of the bond increases. The short position, on the other hand, has a decrease in the price of bond if interest rates fall. This would imply negative 2.5 years duration.
What is a long duration?
adjective. 1That lasts for or involves a relatively long period of time. 2Finance. Maturing or becoming effective only after a relatively long period of time.
Is higher or lower duration better?
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).Consequently, the shorter-maturity bond would have a lower duration and less risk. Coupon rate: A bond’s coupon rate is a key factor in calculation duration.
What is duration example?
Duration is defined as the length of time that something lasts. When a film lasts for two hours, this is an example of a time when the film has a two hour duration.Rationing will last at least for the duration.
What are effective duration and effective convexity and when are they useful?
Duration and convexity are two tools used to manage the risk exposure of fixed-income investments. Duration measures the bond’s sensitivity to interest rate changes. Convexity relates to the interaction between a bond’s price and its yield as it experiences changes in interest rates.
How is duration calculated?
The formula for the duration is a measure of a bond’s sensitivity to changes in the interest rate, and it is calculated by dividing the sum product of discounted future cash inflow of the bond and a corresponding number of years by a sum of the discounted future cash inflow.
What is effective convexity?
The effective convexity of a bond is a curve convexity statistic that measures the secondary effect of a change in a benchmark yield curve.Similarly, we use the effective convexity to measure the change in price resulting from a change in the benchmark yield curve for securities with uncertain cash flows.
How does duration differ from maturity?
In plain English, “duration” means “length of time” while “maturity” denotes “the extent to which something is full grown.” When bond investors talk about duration it has a very specific meaning: The sensitivity of a bond’s price to changes in interest rates.
