Lyrics

[Verse 1]
Treasury bonds are puzzle pieces, prices scattered on the floor
Each maturity tells secrets of the rates we're searching for
Start with shortest-term instruments, six months or maybe one
Calculate their implied returns, the bootstrapping has begun

[Chorus]
Bootstrap up the curve, bond by bond we climb
Short to long maturity, building rates through time
Strip away the coupons, find the zero yield
Spot rates emerge like diamonds from the pricing field

[Verse 2]
Take a two-year government bond, it pays you twice a year
Discount back the first coupon with the one-year rate that's clear
What remains is principal plus that final interest flow
Solve for what discount rate makes present value equal what we know

[Chorus]
Bootstrap up the curve, bond by bond we climb
Short to long maturity, building rates through time
Strip away the coupons, find the zero yield
Spot rates emerge like diamonds from the pricing field

[Bridge]
Iteration after iteration, each new rate unlocks the next
Three-year bonds need one and two-year rates to be perplexed
Five years needs the previous four, it's mathematical cascade
Risk-free curve takes shape before us, foundation rates we've made

[Verse 3]
Government securities only, credit risk we must exclude
Corporate bonds have extra spread, they'd make our curve skewed
Pure time value of money, that's what spot rates should reveal
Bootstrap method guarantees our zero-coupon curve is real

[Outro]
From the shortest bills to longest bonds
The spot rate curve responds
Bootstrap methodology
Creates our yield harmony
