【Pricing Fundamentals】What a Carry Trade Is in Commodity Markets

A commodity carry trade refers to the strategy of simultaneously buying a commodity in the spot market and selling it in the forward or futures market at a higher price, locking in a profit equal to the difference between the two prices minus the costs of storing and financing the commodity over the intervening period. The carry trade is also called a cash-and-carry arbitrage, and it is one of the fundamental mechanisms by which commodity markets maintain the relationship between spot prices and forward prices.
The carry trade is possible when a commodity market is in contango — when forward prices are higher than spot prices. The forward premium compensates holders of physical inventory for the cost of storage, insurance, and financing. When the forward premium exceeds these costs, a riskless profit is available to anyone with access to storage and financing. When the forward premium is less than the carrying cost, physical holders would rather sell spot and buy forward — effectively doing the reverse carry — which pushes spot prices up and forward prices down until equilibrium is restored.
How the Carry Trade Works in Practice
The mechanics of a carry trade in physical commodities are straightforward. First, the trader identifies a commodity where the forward price exceeds the spot price by more than the total carrying cost. Second, the trader buys the commodity in the spot market. Third, simultaneously, the trader sells a futures or forward contract for delivery at the forward date, locking in the forward price. Fourth, the trader stores the commodity until the delivery date, pays storage and financing costs, and delivers the commodity against the short futures position.
For example, assume crude oil spot is trading at USD 78 per barrel and the twelve-month futures price is USD 84 per barrel. Annual storage cost in a floating storage vessel or tank farm is USD 3 per barrel. Annual financing cost at 6% on USD 78 is approximately USD 4.68 per barrel. Total carrying cost: USD 7.68 per barrel. The forward premium of USD 6 per barrel (USD 84 minus USD 78) is less than the carrying cost of USD 7.68 — the carry trade is not profitable at these prices. If the twelve-month futures price were USD 86 per barrel, the carry trade would be profitable by USD 86 minus USD 78 minus USD 7.68 = USD 0.32 per barrel.
During the oil market contango of early 2020, when demand collapsed due to the global COVID-19 lockdowns and spot oil prices fell sharply, the forward premium became so wide that traders filled every available storage facility — including VLCC supertankers anchored at sea as floating storage — to exploit the carry. Dozens of vessels were taken off the shipping market for storage purposes, tightening vessel availability and increasing freight rates simultaneously.
What Limits the Carry Trade in Practice
Several real-world constraints limit the scalability and profitability of commodity carry trades. Storage capacity is finite — once all available tank farm, warehouse, or vessel storage is occupied, additional carry trades cannot be executed regardless of the forward premium, and the competition for remaining storage drives up storage costs, compressing carry margins.
Financing availability is a second constraint. A carry trade requires capital to purchase the spot commodity. Trading companies with larger balance sheets and cheaper financing costs can execute carry trades more profitably than smaller participants. This is one reason why large commodity trading houses with significant storage infrastructure and low-cost revolving credit facilities systematically extract carry returns that smaller traders cannot.
The carry trade enforces a mechanical relationship between spot and forward prices — when the forward premium is too wide, carry traders buy spot and sell forward until the excess is arbitraged away, and this arbitrage pressure is what keeps commodity forward curves aligned with their fundamental cost-of-carry foundation.
