Theory is nice. But at some point you have to price actual products that real people are trading. Chapter 38 of Wilmott’s book takes two interesting fixed-income contracts and walks through how to price them from scratch. No hand waving. Just the math, the logic, and even the code.
Swaps are one of the biggest markets in finance. The total notional principal is comfortably in the hundreds of trillions of dollars. Chapter 14 of Wilmott’s book explains how they work, why they exist, and how they connect to the bond pricing we covered in the previous post.
We are leaving the world of options for a bit and entering the world of fixed income. This is the world of bonds, interest rates, and cashflows. Chapter 13 of Wilmott’s book is a self-contained introduction that does not require anything from earlier chapters. If you have ever wondered what a yield curve is or why bond traders care about something called “duration,” this is the post for you.
