Introduction to Commodities and Commodity Derivatives

Most investors reach commodities through futures, swaps and indexes rather than physical barrels, bushels or ingots, so returns depend as much on the shape of the futures curve as on spot prices. This module explains how the main commodity sectors are produced and consumed, why commodities cannot be valued like stocks and bonds, which theories explain contango and backwardation, and how to split a futures position's return into price, roll and collateral components. It closes with commodity swaps and the index construction choices that drive index returns.

What you will learn

1. Compare the main commodity sectors and explain how their production and consumption life cycles affect supply, storage and prices.

Sectors: energy, grains, industrial metals, livestock, precious metals and softs, each with its own life cycle.
Seasonal demand (energy) or seasonal supply (grains) creates predictable patterns in inventories and futures curves.
Long supply lags (new mines, cattle herds) make prices react strongly to demand shocks.
Storability matters: easily stored metals smooth shocks; costly storage (natural gas, livestock) allows sharp price moves.
Weather and concentrated growing regions dominate risks for grains and softs.

2. Contrast the valuation of commodities with that of equities and bonds, and describe the participants in commodity futures markets.

Commodities produce no cash flows, so they are valued from supply, demand and the cost of carry rather than by discounting.
Futures prices reflect spot, financing and storage costs, convenience yield, expectations and risk premiums.
Hedgers (producers short, consumers long) transfer price risk to speculators, who provide liquidity.
Arbitrageurs with physical capabilities keep spot, futures and regional prices aligned.
A hedger's effective price = spot price + gain or loss on futures, so basis risk remains.

3. Analyse contango and backwardation and compare the insurance, hedging pressure and storage theories of commodity futures returns.

Contango: later futures prices above nearer ones; backwardation: later prices below.
Carry model: F = S(1 + r + storage - convenience yield); high inventories mean contango, scarcity means backwardation.
Insurance theory: producers pay speculators a premium, so futures sit below expected spot (normal backwardation).
Hedging pressure: the dominant hedger side (producers or consumers) determines the sign of the premium.
Theory of storage: inventory levels drive convenience yield and the shape of the curve.

4. Calculate the price, roll and collateral components of the total return on a fully collateralised commodity futures position.

Total return on a fully collateralised position = price return + roll return + collateral return.
Roll return = (expiring contract price - new contract price) / expiring contract price, scaled by the share of the position rolled.
Backwardation gives positive roll return; contango gives negative roll return.
Excess return = price + roll; total return adds the interest on collateral.
Spot price changes can differ widely from futures investors' returns because of roll.

5. Explain commodity swaps and how index construction choices affect commodity index returns.

Fixed-for-floating swaps lock in prices for producers and consumers; total return swaps give index exposure against a floating rate.
Basis swaps hedge location or quality differences; variance swaps trade realised volatility.
Production weighting concentrates indexes in energy; capped or equal weighting diversifies.
Roll methodology (front month versus deferred or optimised) can change returns sharply in contango.
Rebalancing adds return in mean-reverting markets and costs return in trending markets.

Module at a glance

Each commodity sector has its own life cycle; supply lags and storability decide how violently prices react to shocks.
Commodities produce no cash flows: value comes from supply, demand, carry costs and convenience yield.
Producers hedge short, consumers hedge long, speculators supply liquidity and arbitrageurs keep prices aligned; basis risk remains.
Contango reflects ample inventories and carry costs; backwardation reflects scarcity and high convenience yield.
Insurance theory, hedging pressure and the theory of storage explain risk premiums and curve shapes differently.
Total return on a fully collateralised position = price return + roll return + collateral return; contango makes roll return negative.
Swaps fix prices or deliver index returns; index weighting, roll and rebalancing rules drive large differences in index returns.
