Lyrics

[Verse 1]
Sarah's got a pension fund, payments due in ten long years
Interest rates keep changing, filling her with countless fears
When rates go up her bonds drop down, when rates fall bonds rise high
She needs a way to match the risk and keep her portfolio dry

[Chorus]
Duration matching, immunization
Shield your portfolio from rate fluctuation
Match the duration of assets to your liability's time
Duration matching, immunization
Protect your future obligation
When durations align, your risk declines every time

[Verse 2]
Duration measures sensitivity to interest rate moves
It's like a weighted average of when your cash flows come through
If liability duration is eight and your bonds are eight too
Then rate changes affect them both in ways that are true

[Chorus]
Duration matching, immunization
Shield your portfolio from rate fluctuation
Match the duration of assets to your liability's time
Duration matching, immunization
Protect your future obligation
When durations align, your risk declines every time

[Bridge]
When rates rise and bond prices fall
Your assets and liabilities drop and that's all
When rates drop and bond prices climb
Both sides move up at the same time
Perfect balance, perfect hedge
Keep your promises right on the edge

[Verse 3]
Monitor and rebalance as time passes by
Duration drifts naturally, don't let it slide
Cash flows and yield changes mean you must adjust
Keep those durations matched, it's really a must

[Chorus]
Duration matching, immunization
Shield your portfolio from rate fluctuation
Match the duration of assets to your liability's time
Duration matching, immunization
Protect your future obligation
When durations align, your risk declines every time

[Outro]
Sarah's fund is safe now, her future payments secured
Duration matching strategy has her interest risk cured
Match your durations well, and you'll sleep sound at night
Immunization strategy keeps your portfolio right
