Commodity Trading Strategies Guide

At a glance

Access: Futures, ETFs holding futures, or producer equities
Key structure: The forward curve: contango or backwardation
Return sources: Trend, carry (roll yield), and seasonality
Distinctive risk: Supply shocks and physical delivery mechanics

Key takeaways

A long commodity position earns or loses roll yield every month regardless of spot price, which frequently dominates the total return.
Backwardation indicates scarcity and produces positive carry for longs; contango indicates abundance and storage costs, producing a persistent drag.
Seasonality in commodities is more credible than in financial markets because production and consumption genuinely follow the calendar, but the curve usually prices it already.
Spread trading between contract months isolates curve dynamics and requires much less margin than outright positions.
Commodity ETFs holding futures are not spot exposure: their long-run returns can differ dramatically from the commodity price.

The forward curve is the main event

Commodities trade as a series of contracts for delivery in different months. The relationship between those prices, the forward curve, encodes storage costs, financing, and expectations about future supply and demand.

Curve shape	What it means	Effect on a long position
Contango (upward sloping)	Ample supply; storage and financing costs dominate	Negative roll yield: each roll buys a more expensive contract
Backwardation (downward sloping)	Immediate scarcity; buyers pay a premium for prompt delivery	Positive roll yield: each roll buys a cheaper contract
Flat	Balanced conditions	Minimal roll effect
Seasonal humps	Known demand or harvest patterns priced into specific months	Pattern is already in the curve, so trading it requires a deviation view

Market in contango:
  Front month  = 70.00
  Next month   = 71.50

Rolling a long position each month:
  Sell at 70.00, buy at 71.50  ->  lose 1.50 per roll
  Over 12 months, if spot is unchanged at 70.00,
  the rolled position has lost roughly 18.00, about 25%.

This is why a commodity ETF can fall substantially over a year
in which the commodity price itself was flat.

Why roll yield can dominate the price move.

The main commodity strategies

Strategy	Signal	Notes
Trend following	Price breakouts across a basket of commodities	The traditional core of managed futures
Carry / roll yield	Long backwardated markets, short contango markets	Well documented cross-sectional effect
Calendar spreads	Relative value between contract months	Isolates curve dynamics, much lower margin
Seasonality	Production and consumption cycles	Genuine mechanism, but usually priced into the curve
Inter-commodity spreads	Relationships such as crack and crush spreads	Tracks processing economics rather than outright price
Producer equity versus commodity	Mining or energy companies versus the underlying	Adds equity and company-specific risk
Inventory and positioning signals	Storage data and commitment-of-traders reports	Slow-moving, useful as context rather than triggers

Spread trading: the professional approach

Rather than betting on the direction of crude oil, a spread trader might buy the December contract and sell the June contract, taking a position on how the curve evolves rather than on the outright price. This has several structural advantages.

Lower margin. Exchanges recognise the offsetting nature of the legs, so margin for a calendar spread is a fraction of an outright position.
Lower volatility. Both legs respond to broad market moves, so the spread reflects structural change rather than the daily macro noise.
A clearer economic thesis. Spreads express views about storage, supply timing, and refinery economics, which are more tractable than forecasting outright prices.
Less exposure to macro shocks, since a broad risk-off move affects both legs similarly.

The trade-offs are real: spread moves are smaller, so more contracts are needed for the same profit; liquidity in deferred months is thinner; and a spread can move sharply when the curve restructures, which is precisely the event that spread traders are exposed to.

Calendar spread: Long one delivery month, short another in the same commodity. Expresses a view on the curve.
Crack spread: Crude oil against refined products, reflecting refining margins.
Crush spread: Soybeans against soybean meal and oil, reflecting processing economics.
Inter-commodity spread: Two related commodities, such as gold against silver or corn against wheat, where a historical ratio exists.

Practical considerations

Never take delivery. Close or roll physically settled contracts before first notice day. Retail accounts cannot handle delivery of physical commodities.
Understand the contract specification. Contract sizes vary enormously: one crude contract is 1,000 barrels, one gold contract is 100 ounces. Notional exposure is easy to underestimate.
Watch for limit moves. Some commodity markets halt after a defined daily move, meaning you cannot exit until the next session.
Supply shocks are genuinely unpredictable. Weather, geopolitics, strikes, and export bans produce moves that no technical rule anticipates. Position size accordingly.
Liquidity concentrates in the front months. Deferred contracts can be very thin, which matters for spreads and for longer-dated positions.
Choose the right vehicle. ETFs holding futures inherit roll costs; ETFs holding physical metal do not; producer equities add company risk.

Frequently asked questions

Why did my commodity ETF lose money when the commodity rose?

Almost certainly negative roll yield. Funds holding futures must roll positions forward each month, and in contango that means selling a cheaper contract and buying a more expensive one. Over a year this drag can exceed 20 percent, so the fund can decline even as spot prices rise.

Are commodities a good inflation hedge?

Energy and industrial metals have often risen during inflationary episodes, and broad commodity indices have historically shown a positive relationship with unexpected inflation. However, roll yield can offset the price gain substantially, and the relationship is inconsistent over shorter periods. Commodity exposure is a volatile and imperfect hedge rather than a reliable one.

What is the easiest commodity to start with?

Gold, through a physically backed ETF or a micro futures contract. It has deep liquidity, no seasonality, no physical delivery complications for retail traders using cash-settled or physically backed products, and no crop or weather risk. Energy and agricultural markets are considerably more complex.

How do I trade commodity seasonality?

Usually through calendar spreads rather than outright positions, because known seasonal patterns are already reflected in the curve. The tradeable element is typically the deviation from the expected seasonal pattern, such as inventories being unusually high going into a demand season, rather than the pattern itself.

Do I need a futures account to trade commodities?

Not necessarily. ETFs provide access through a standard brokerage account, though futures-based ones carry roll costs. Producer equities offer indirect exposure with added company risk. Futures offer the cleanest exposure and the most control over the curve position, at the cost of margin complexity and expiry management.
