What is the Macaulay duration and how to calculate it?
It is the holding period for which reinvestment and price risks are rebalanced. It is calculated by PV of future cash flows/PV of the bond
What is the modified duration and how is it calculated?
Measures a bond’s price sensitivity to interest rate changes. Higher duration = greater price sensitivity to interest rate changes. It is equal to Macaulay Duration/ (1+r)
How do you calculate the annualized Mod Dur?
AnnModDur = ((Pv-)-(Pv+))/2PVoDyield
Relationship between investment horizon and MacDur?
MacDur=duration gap + investment horizon
What is money duration and how is it calculated?
Measures the dollar (or currency) change in a bond’s value for achange in interest rates. Higher money duration = bigger $ impact
MonDur=AnnModDur*PVFull
What is a Price Value of Basis Point and how is it calculated?
The change of full price if yield changes by 1bp. PVBP = (PV-)-(PV+)/2
What is the MacDur of a Floating note?
MacDur floating = (T-t)/T
Effective duration?
Measures a bond’s price sensitivity to small parallel shifts in the yield curve, accounting for embedded options. Higher effective duration = greater interest rate risk.
(P-)-(P+)/2PoDcurve
What does key rate duration measure?
It provides insights on a bond‘s sensitivity to changes in the benchmark yield curve
What is the Macaulay duration and the modified duration of a zero coupon bond?
Macaulay duration = Time to maturity
ModDur = MacDur/(1+annual yield)
Macaulay duration
Weighted average time of cash flows
Modified duration
Mac Dur / (1 + r)
Price sensitivity formula
–ModDur × Δyield
PVBP
Price change for 1 bp move
Money duration
ModDur × price
Duration gap
Mac Dur – horizon
Positive duration gap
Price risk dominates
Negative duration gap
Reinvestment risk dominates
Zero-coupon duration
Equal to maturity
Perpetual duration
(1+r)/r
FRN duration
Time to next reset
Duration increases with
Maturity
Duration decreases with

Realized return = YTM if
Hold to maturity + reinvest at YTM
