Preface
Almost everything written about commodities is written about one commodity, or about one job inside the trade. There are books about oil. There are books about grain merchants. There are books that teach the arithmetic of futures pricing and stop at the arithmetic, and books that give the entire subject a single chapter inside a wider guide to markets. What is difficult to find is the connected account: the one that begins with copper still in the ground and ends with a number on a screen, and treats everything in between as one subject rather than six unrelated ones.
That is the gap this book was written to close. It covers the physical end of the industry, extraction and cultivation, tankers and pipelines, grain elevators and storage tanks, grading and certification. It covers the contractual end, the standardised specifications that make one barrel substitutable for another, the clearinghouse that stands between every buyer and seller, the delivery notices that arrive whether or not a trader wants them. It covers the mechanical end, tick values and contract multipliers, margin and order types, liquidity windows and expiration calendars. And it covers the forces above all of that, inventory reports and supply shocks, currency strength, sanctions, and the long structural shifts that outlast any cycle. The aim is breadth held together by logic, not depth in one corner. There is no chapter here on the internal accounting of an integrated oil major, and none on the fine detail of West African cocoa logistics. Those books exist and they are worth reading once you understand where they sit. What this book gives you is the whole architecture at once.
It is a manual rather than a story. It does not build towards a revelation and it does not have to be read in the order it is printed. Every heading is written to stand on its own, so you can open the book at the section on convenience yield, or at the section on choosing a broker, and find something complete rather than something that assumes you were present for the previous forty pages. Where a section genuinely depends on an idea developed elsewhere, it names the chapter, so you always know where to go and never have to guess whether you have missed something.
Two conventions run through the text, and both exist to keep you reading rather than searching.
The first is that every industry term is defined in square brackets the moment it first appears, immediately after the word itself. In Chapter 1 the sentence reads: Contango [a market condition where futures prices are higher than the current spot price, usually reflecting the costs of carrying or storing the commodity until the future delivery date] occurs when futures prices are higher than the spot price. The definition sits inside the sentence that first needs it, so nothing is used before it has been explained. Every term defined this way reappears in the Key Terms list at the end of its chapter and again in the Glossary at the back, which means a term you half-remember from two hundred pages earlier is always recoverable in seconds.
The second is that specific claims, outside figures, and reasoning that did not originate here carry a small number in square brackets. Chapter 1 states that opening a new copper mine takes fifteen years or more on average from discovery to first production [3]. That bracketed 3 refers to the third entry under Chapter 1 in the Notes at the back of the book, where the source is named in full. Where a figure is checkable, the number tells you where to check it. Where a claim belongs to someone else, the number tells you whose it is. You are never asked to take a number on trust.
The chapters are ordered by what each idea requires, not by convention about where a book on markets ought to begin. You are not shown a futures curve before you have been shown that storage costs real money every month. You are not shown a margin call before you have been shown what a contract is actually worth. The sequence runs: what a commodity is and why one unit substitutes cleanly for another, then where it comes from and what it costs to move and hold, then how a price becomes reachable at all and through which instruments, then the mechanics of holding a position through expiration and settlement, then what that position costs when it moves against you, and finally the forces that move prices and what a reasonable role in these markets looks like. Nothing is assumed before it has been built.
If you have never seen a futures contract, begin at the first page of Chapter 1 and take the chapters in order. Nothing is assumed of you beyond attention. If you already work with these markets, you will find your own entry point, and it is usually not where you expect. A trader who has held crude oil for years may never have worked through why a grain merchant’s storage decision sets the shape of a curve. Someone who has spent a career in the physical trade may never have calculated what a single tick is worth in cash. An analyst fluent in supply and demand may never have read how a delivery notice is assigned, or why the assignment is outside anyone’s control. The book was built so that both readers can use the same pages.
The practical instruction is simple. Read it once from beginning to end, including the parts that look familiar, because the sequence is doing work that the individual sections cannot do alone. Then stop treating it as a book and start treating it as a reference. Keep it where you can reach it, and return to the heading you need when the market puts a question in front of you. It was written to be opened repeatedly, not admired once.
