Derivatives are financial contracts whose value depends on an underlying asset like stocks, bonds, or commodities. Common types include futures, forwards, options, and swaps, each priced using distinct models and market principles. Additionally, innovative derivatives may link to non-traditional factors such as weather or carbon emissions.

Key Insights

• Derivative prices stem from the value of underlying assets or securities.
• Pricing techniques vary by derivative type, reflecting contract features and market dynamics.
• Futures prices relate closely to spot prices plus a basis reflecting market conditions.
• Options pricing incorporates time to expiry, volatility, strike price, and interest rates.
• Swaps are valued by equating present values of fixed and floating cash flow streams.

Understanding Futures Pricing

Futures contracts lock in prices today for buying or selling assets at a future date. Their value is tied to the spot price of the underlying commodity but often differs due to the basis—the difference between futures and spot prices. This basis fluctuates due to factors like delivery location, product quality, and time until contract expiry.

For example, a corn futures contract for 5,000 bushels priced at $5 per bushel equals a $25,000 contract value. Futures are standardized for trading on exchanges, and their prices move with supply and demand dynamics.

Unlike futures, forwards are customizable, over-the-counter contracts negotiated directly between parties, offering flexibility in terms and conditions.

Options Pricing Fundamentals

Options grant the right, without obligation, to buy or sell an asset at a predetermined strike price before expiration. Pricing models aim to estimate the likelihood an option will finish in-the-money (ITM). Key inputs include the underlying asset price, strike price, volatility, time to expiration, and interest rates.

Longer time horizons and higher volatility increase the chance an option will be profitable at expiry. Rising interest rates generally lead to higher option premiums.

The Black-Scholes model remains the cornerstone for option valuation, integrating these variables to compute theoretical fair value. Alternative models like binomial and trinomial trees also provide robust pricing frameworks.

Swaps Pricing Explained

Swaps involve exchanging cash flows between parties over time and can be tailored extensively. The simplest form, an interest rate swap, typically exchanges fixed payments for floating rate payments.

At inception, the swap’s value is zero because the present values of the fixed and floating cash flows are equal. Notional amounts are not exchanged; if they were, the swap would resemble exchanging fixed-rate bonds for floating-rate bonds of equal principal.

Swap valuation relies on discounting these cash flows and comparing fixed versus floating rate streams to determine fair value throughout the contract’s life.
