The 'Father of Options': How Illicit Moneylending via Put-Call Parity Made a Millionaire
Did you know the "Father of Options" circumvented 19th century usury laws via financial engineering to make $?
Let's dive into the fascinating story of how Russell Sage leveraged put-call parity to become a millionaire, and how put-call-LP parity revolutionizes DeFi options๐งต
In this thread we'll:
- Show how Russell Sage made millions by subverting the law with options
- Use monkeys & bananas to explain put-call parity
- Explain why "put-call-LP" parity for DeFi options is as groundbreaking as put-call parity was for TradFi options
What is Usury?โ
Usury, aka predatory lending, is charging an excessive rate of interest on a loan.
Historically, usury was defined as charging any interest on a loan and was condemned by major religions & prominent philosophers (Moses, Buddha, Muhammad, Aristotle...).
In 1867, Russell Sage was convicted of violating New York usury laws for charging an 8% annual interest rate on a late loan to a stockbroker. The penalty for Russell was $250 in fines and 5 days in prison (source here).
But this didn't deter him. Russell used his know-how of options to create synthetic loans. He developed OTC options trading on such a grand scale that he was known as "The Father of Puts and Calls", inventor of straddles & strangles, and the "Money King".
Put-Call Parityโ
But how exactly did the "Money King"๐ฐ๐ create loans through options trading? The answer lies in a fundamental concept found in every financial textbook called "put-call parity", which can be used to create synthetic loans.
Imagine a seesaw with 4 types of fruit: apples๐, peaches๐, cherries๐, and bananas๐.
In order to stay balanced, the seesaw must have a fixed ratio of apples๐ + peaches๐ on one side, and cherries๐ + bananas๐ on the other side.
Each fruit represents a financial instrument, and the fundamental relationship between the fruits is put-call parity.
- ๐ = asset price
- ๐ = put price
- ๐ = bond price
- ๐ = call price
Put-call parity: ๐ + ๐ = ๐ + ๐
- "Mon[k]ey King"๐ต๐ be like: "Me like loanshark โ me want high interest rate!"
- Buying ๐(bonds) is a fancy way of saying: "Me lend you some money in exchange for interest."
โ So ๐ต๐ can loanshark by buying ๐(bonds โ in this case, high yield ones)! ๐คฏ
But ๐ต๐ couldn't legally buy bananas๐ (bonds โ the high yield ones). ๐ฉ๐ฉ๐ฉ๐ต๐โ๏ธ๐ฎ
Instead, he:
- Bought apples๐(asset)
- Sold cherries๐ (calls)
- Bought peaches๐ (puts)
โ Effectively purchasing bananas๐ (bonds) to create loans at higher interest rates than was legal!
Put-Call-LP Parityโ
Just as "put-call parity" is fundamental to options, "put-call-LP parity" is fundamental to DeFi options.
Panoptic begins w/ the simple observation that providing concentrated liquidity in Uniswap V3 is analogous to selling options in TradFi.
LP = -Put ๐คฏ
Let's call this observation "put-LP parity": LP = -Put (๐ = -๐)
Which means: -LP = Put (-๐ = ๐)
โ Panoptic lets you buy peaches ๐ (puts) by selling lemons ๐ (LPs) ๐คฏ
How do you buy ๐ (calls)? Answer: lab-grown synthetics!
- Put-call parity: ๐ = ๐ - ๐ + ๐
- Put-LP parity: ๐ = -๐
- โ Combined: ๐ = ๐ - ๐ - ๐
โ You can buy ๐ (calls) by buying ๐ (asset), selling ๐(bonds), and selling ๐ (LPs)๐คฏ
Panoptic Labsโข synthesized a new type of ๐ and ๐: These ๐ and ๐ are shelf stable because they NEVER expire!
Panoptions are a novel type of options:
- Perpetualโพ๏ธ
- Oracle-free๐ฎ
- Permissionless๐ค
- Made for DeFi๐

Summary:
- Put-call parity describes the relationship b/t puts and calls
- Russell Sage took advantage of this to make high interest loans
- Put-call-LP parity describes the relationship b/t put, calls, & LP
