Hi David, I notice that you have a different way of calculating the DV01 in your notes. Indeed, Tuckman defines it as follows: (1/)*(dP/dy). There are two items that must be clarified with respect to your question: Are you assuming an interest rate swap (IRS) at mid-market, i.e. at-the-money (ATM) or. In finance, the duration of a financial asset that consists of fixed cash flows, for example a bond, The formula can also be used to calculate the DV01 of the portfolio (cf. below) and it can be generalized to include risk factors beyond interest.

From Wikipedia, the free encyclopedia. Thread starter vjoyram Start date Jul 28, Indeed, Tuckman defines it as follows: Duration is dvv01 linear measure of how the price of a bond changes in response to interest rate changes.

Bond duration

This is because the issuer can redeem the old bond at a high coupon and re-issue a new bond at a lower rate, thus providing the issuer with valuable optionality. When the yield is expressed continuously compounded, Macaulay duration and modified duration are numerically equal. Calculqtion financial markets, yields are usually expressed periodically compounded say annually or semi-annually instead of continuously compounded.

Banks and banking Finance corporate personal public. Returns to Bondholders from Naive and Optimal Strategies. The total PV will be:. For every-day use, the equality or near-equality of the values for Macaulay and modified duration can be a useful aid to intuition.


Resources Latest reviews Search resources. And also to apply. For a standard bond the Macaulay duration will be d0v1 0 and the maturity of the bond.

Check date values in: Modified duration is defined as the logarithmic derivative of price with respect to yield, and such a definition will apply to instruments that depend on yields, whether or not the cash flows are fixed. Neither of these are risks in the true sense of market moves because they both assume the cslculation remains constant whilst the fixed rate on the contract moves.

It is often measured per 1 basis point – DV01 is short for “dollar value of an 01” or 1 basis point. All four have a year maturity but the sensitivity to interest rates, and thus the risk, will be different: Modified duration is also useful as a measure of the sensitivity of a bond’s market price to finite interest rate i.

DV01 Computation

DV01 is duration in different units plus the “price infection. The effective duration is a discrete approximation to this latter, and will require an option pricing model.

Mortgage-backed securities pass-through mortgage principal prepayments with US-style or year fixed rate mortgages as collateral are examples of callable bonds. Attack68 2, 2 Note that the minus sign can be added or removed depending if you are paying or receiving the swap.


DV01 or dollar duration can be used for instruments with zero up-front value such as interest rate swaps where percentage changes and modified duration are less useful. Thinking of risk in terms of interest rates or yields is very useful because calculahion helps to normalize across otherwise disparate instruments.

Strictly speaking, Macaulay duration is the name given to the weighted average time until cash flows are received, and is measured in years.

Similar risk measures first and second order used in the options markets are the delta and gamma. The concept of modified duration can be applied to interest-rate sensitive instruments with non-fixed cash flows, and can thus be applied to a wider range of instruments than can Macaulay duration.

Thomas Ho [9] introduced the term key rate duration. The differences between the two are as follows:. These are two different things.

This formula can be used to calculate the VaR of the portfolio by ignoring higher order terms.
