Lyrics

[Verse 1]
When future payments loom ahead, your portfolio needs a shield
Interest rates can twist and turn, making bond values wheel
Duration matching holds the key, a fortress you can build
Align your assets to the clock when obligations must be filled

[Chorus]
Duration matching, immunization
Lock your timeline, stop the variation
When rates climb up, your bonds fall down
But matching duration keeps you sound
Duration matching, immunization
Future payments, no frustration

[Verse 2]
Macaulay measures weighted time, each cash flow has its place
Modified duration shows the swing when interest rates give chase
Calculate your liability's beat, then match it bond by bond
Duration gaps spell danger zones where losses could abscond

[Chorus]
Duration matching, immunization
Lock your timeline, stop the variation
When rates climb up, your bonds fall down
But matching duration keeps you sound
Duration matching, immunization
Future payments, no frustration

[Bridge]
Convexity adds the second twist
Price curves bend, they can't resist
Rebalance when the gap grows wide
Keep duration matched, side by side
Present value stays on track
When your durations echo back

[Verse 3]
Pension funds and insurance firms, they live this every day
Promise payments years from now, come sunshine or come gray
Dedicated portfolios with duration locked in tight
Immunized against the swings that keep treasurers up at night

[Chorus]
Duration matching, immunization
Lock your timeline, stop the variation
When rates climb up, your bonds fall down
But matching duration keeps you sound
Duration matching, immunization
Future payments, no frustration

[Outro]
Match the duration, win the game
Interest risk won't stake its claim
