Key rate duration measures the duration of a security or portfolio at a specific maturity point along the entirety of the yield curve. When keeping other maturities constant, the key rate duration can be used to measure the sensitivity in a bond's price to a 1% change in yield for a specific maturity.

The calculation is as follows:

The formula for calculating key rate duration uses three separate variables. They are:

It can be difficult to interpret an individual key rate duration because it is very unlikely that a single point on the Treasury yield curve will have a upwards or downwards shift at a single point while all others remain constant. It's useful for looking at key rate durations across the curve and looking at the relative values of key rate durations between two securities.

Key rate duration measures the fluctuation of a security or portfolio value at a specific maturity point on the yield curve. Keeping other maturities constant, the key rate duration is a measure of the sensitivity in a security's price to a 1% change in yield for a given maturity. Jul 1, 2019

The key rate determines the interest rate of banks on debts when they don't meet up with their required reserves. The Federal Reserve or other banks may lend them for a very short period. Oct 3, 2019

This is when a bond price moves along with interest rates. In other words, negative duration happens when the bond prices go up along with interest rates and vice versa. Negative duration means negative bank equity.

A convexity number is the percent change in modified duration from a 1% change in yield. The impact of including convexity in a price change calculation for a 1% change in yield is estimated by multiplying the convexity by 1%^2=1%*1%. Nov 20, 2010

Duration is a measure of the bond’s sensitivity to interest rate changes.

How to Calculate Effective Duration V–Δy – The bond's value if the yield falls by a certain percentage. V+Δy – The bond's value if the yield rises by a certain percentage. V0 – The current value of cash flows (i.e. the bond's price) Δy – The change in the yield value.

High convexity implies a dramatic change in price given a move in interest rates. If your bond continues to experience negative convexity, it loses value. Jun 25, 2013
