What Can Be Traded in a Commodities Market

The tickers move, calendars fill up, and it’s easy to forget the simple question: what can be traded in a commodities market? Here’s the calm version with plain-language definitions, concrete examples, and a side-by-side view you can reuse.

“A commodity futures contract is an agreement to buy or sell a particular commodity at a future date; the price and amount are fixed.”

First things first: what is commodity market

A commodity market is where raw or primary goods change hands in spot deals or via derivatives like futures and options. Think energy, metals, and agricultural products.

“The S&P GSCI is one of the most widely recognized commodity benchmarks; broad-based and production-weighted.”

The landscape at a glance: commodity markets by group

Group	Examples you can trade	Typical contract unit	Where specs live
Energy	WTI crude, Brent crude, natural gas	WTI: 1,000 barrels; Brent: 1,000 barrels	CME (WTI) and ICE (Brent) contract pages list units and ticks.
Metals	Gold, copper, aluminum	Gold: 100 troy oz (COMEX)	Exchange spec sheets show multipliers and tick values.
Agriculture (grains & oilseeds)	Corn, wheat, soy complex	Corn: 5,000 bushels	CME corn specs confirm size and quotation.
“Softs” & other ag	Coffee, sugar, cocoa, cotton	Exchange-specific	See ICE and CME product specs for each contract.
Industrial metals venues	Copper, nickel, zinc	LME, COMEX contracts	Venue rule changes and inventory rules affect trading.

A few concrete contract examples

• WTI Crude (NYMEX CL): unit 1,000 barrels; minimum tick 0.01 dollars per barrel equals 10 dollars per tick.
• Brent Crude (ICE B): unit 1,000 barrels; minimum price fluctuation 0.01 dollars per barrel.
• Gold (COMEX GC): contract size 100 troy ounces; tick 0.10 dollars per oz equals 10 dollars per tick.
• Corn (CBOT ZC): contract unit 5,000 bushels; quoted in cents per bushel.
  

What exactly can you trade (and how)

Access path	What you actually trade	Why people choose it	Watch-outs
Exchange futures	Standardized contracts on energy, metals, gas	Liquidity, central clearing, transparent specs	Margin and daily P/L mean discipline required.
Options on futures	Right, not obligation, on a futures contract	Defined risk structures	Greeks and assignment rules add complexity.
Spot/forwards (OTC)	Bilateral deals, customized terms	Tailored hedges for commercial users	Counterparty risk and documentation.
Index products & ETPs	Baskets tracking commodity indices (e.g., GSCI)	Broad exposure via securities account	Tracking and fees vs underlying futures.

“Futures contracts are traded on organized exchanges that set standardized terms for the contracts.”

Why conditions change across commodity markets

Global supply, inventories, and policy can reshape price behavior. Recent research highlights how shocks (pandemics, wars, climate) alter energy, metals, and agriculture dynamics for years, not weeks.

Reading the curve without math headaches

Futures may trade above or below spot depending on storage, financing, and inventory (contango vs backwardation). That’s normal. What matters is your carry cost and roll timing, which differ by commodity and season.

Costs and frictions you feel on tickets

• Tick size and tick value (e.g., CL’s $10 per tick; GC’s $10 per tick) drive P/L swings.
• Slippage and spread widen around scheduled reports and thin sessions.

Quick starter map that you can actually use

1. Pick one liquid benchmark (WTI, Gold, or Corn).
   
2. Read the exchange spec sheet for size, tick, and hours.
   
3. Put major release times on your calendar (inventories, crop reports).

FAQ

Is the commodity market only for futures traders

No. Commercials hedge with futures and OTC forwards; investors use index products or producer equities. Futures are just the cleanest price-discovery rail.

Why do WTI and Brent sometimes diverge

Logistics and regional supply differences. Both are 1,000-barrel contracts but different delivery ecosystems and inventories drive spreads.

Do metals markets have different regulations?

Venues implement their own regulations and may modify their positioning or lending policies when stock levels become limited, similar to the actions taken by the LME regarding copper.

Where do I find the exact contract size and tick

Consistently refer to the exchange specifications page for the product, which details units, ticks, trading hours, and relevant codes (such as CL, GC, ZC).
