Key Rate Duration
Key rate duration measures portfolio sensitivity or bond's price sensitivity to independent shifts along the yield curve at selected “key” points (The 13 key points are usually defined as '1M', '3M', '6M', '1Y', '2Y', '3Y', '5Y', '7Y', '10Y', '15Y', '20Y', '25Y', '30Y'). Key rate duration is calculated value in relation to a 1% change in yield for a given maturity. Duration is the value of a 1% change (100 basis points) in yield for a given maturity. Key Rate Duration calculates the price response separately for a 1% change in each zero-coupon rate used to calculate the PV of the bond. Gives a better picture of which parts of the term-structure is responsible for how much of total interest rate risk. The key rate durations can then be summed up to give an overall interest rate risk measure, comparable with modified duration. Key rate duration is quoted as a percentage or in basis points.

Famous quotes containing the words key, rate and/or duration:
“The key to the age may be this, or that, or the other, as the young orators describe; the key to all ages is—Imbecility: imbecility in the vast majority of men, at all times, and even in heroes, in all but certain eminent moments: victims of gravity, customs and fear. This gives force to the strong,—that the multitude have no habit of self-reliance or original action.”
—Ralph Waldo Emerson (1803–1882)
“We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living. Sometimes the inner clock runs itself out long before the outer one, and you see a dead man going through the motions of living.”
—Max Lerner (b. 1902)
“What matters it that man should have a little more knowledge of the universe? If he has it, he gets little higher. Is he not always infinitely removed from the end, and is not the duration of our life equally removed from eternity, even if it lasts ten years longer?”
—Blaise Pascal (1623–1662)
