Cash and carry arbitrage is a sophisticated trading strategy that captures profit from pricing differences between spot and futures markets. By purchasing an asset at a lower spot price and simultaneously selling it at a higher futures price, traders can secure a nearly risk-free return. This approach not only offers profit potential but also enhances market efficiency by aligning prices across different trading venues.
This guide explains how cash and carry arbitrage works, its calculation, real-world examples, and associated benefits. Whether you are an individual investor or a financial professional, understanding this strategy can provide valuable insights into market dynamics and low-risk trading opportunities.
What Is Cash and Carry Arbitrage?
Cash and carry arbitrage is a financial strategy where an investor buys an asset in the spot market and simultaneously sells a corresponding futures contract. The goal is to profit from the price difference between these two markets, after accounting for costs like storage, financing, and insurance.
This technique is based on the "cost of carry" model, which suggests that the futures price should equal the spot price plus the cost of holding the asset until the contract’s expiration. When the futures price exceeds this total, an arbitrage opportunity arises.

How to Calculate Cash and Carry Arbitrage
Calculating potential profit in cash and carry arbitrage involves a straightforward formula:
Profit = (Futures Price − Spot Price) − Cost of Carry
Where:
- Futures Price: The agreed-upon price for future delivery of the asset.
- Spot Price: The current market price for immediate purchase.
- Cost of Carry: Expenses incurred while holding the asset, including storage fees, interest on borrowed funds, insurance, and any foregone income (e.g., dividends).
A positive result indicates a profitable arbitrage opportunity. If the result is zero or negative, the market is efficiently priced, and no arbitrage is possible.
Example of Cash and Carry Arbitrage
Suppose gold is trading at $1,800 per ounce in the spot market. A three-month futures contract is priced at $1,830 per ounce. Assuming the cost of carry (storage, insurance, financing) is $15 per ounce, the potential profit is:
[
\text{Profit} = ($1,830 - $1,800) - $15 = $15
]
In this case, you would:
- Buy one ounce of gold in the spot market for $1,800.
- Simultaneously sell a futures contract at $1,830.
- Hold the gold until the futures contract expires, incurring $15 in costs.
- Deliver the gold and receive $1,830, netting a $15 profit.
This example illustrates a clear arbitrage opportunity. Such opportunities are often short-lived, as traders quickly exploit them, bringing prices back in line.
What Is Reverse Cash and Carry Arbitrage?
Reverse cash and carry arbitrage is the opposite strategy. It involves selling an asset in the spot market while buying a futures contract. This approach is used when the futures price is lower than the spot price, creating a potential profit opportunity.
For instance, if the spot price of an asset is $100 and the futures price is $98, a trader can sell the asset immediately, invest the proceeds, and buy the futures contract. When the contract matures, the trader repurchases the asset at a lower price, earning a profit from the difference.
Benefits of Cash and Carry Arbitrage
Profit Opportunities
This strategy allows traders to earn nearly risk-free profits by capitalizing on temporary price disparities. It is especially useful in volatile markets where pricing inefficiencies are more common.
Market Efficiency
Arbitrageurs help align prices between spot and futures markets. Their trading activities reduce mispricings, leading to more accurate and efficient asset valuation.
Risk Mitigation
Since positions are hedged (long in spot, short in futures), the strategy is largely insulated from market fluctuations. This makes it appealing for risk-averse investors.
Liquidity Provision
Frequent arbitrage trading increases volume in both markets, improving liquidity and reducing transaction costs for all participants.
Diversification
Including arbitrage strategies in a portfolio can enhance diversification and reduce overall risk, as returns are often uncorrelated with broader market movements.
Frequently Asked Questions
What types of assets are suitable for cash and carry arbitrage?
Commodities like gold, oil, and agricultural products are common, along with financial instruments such as index futures and currencies.
How can I identify arbitrage opportunities?
Monitor real-time spot and futures prices. When the futures price exceeds the spot price plus carrying costs, an opportunity may exist. Automated trading tools can help detect these gaps quickly.
What are the main risks involved?
Execution risk, counterparty default, and sudden changes in carrying costs (e.g., interest rates) can affect profitability. However, the strategy is generally low-risk compared to directional trading.
Is this strategy accessible to individual traders?
Yes, though it requires capital, market access, and understanding of derivatives. Many online platforms now offer tools to help retail traders identify and execute arbitrage trades.
How does reverse cash and carry arbitrage differ?
It involves selling spot and buying futures, profiting when futures are undervalued. It is the inverse of the classic strategy and is used in different market conditions.
Do I need specialized software to perform arbitrage?
While not strictly necessary, algorithmic trading platforms can significantly improve speed and efficiency, which is critical since arbitrage windows often close quickly.
Cash and carry arbitrage remains a valuable strategy for traders seeking low-risk returns while contributing to market efficiency. By understanding its mechanics and applications, you can better identify opportunities and incorporate this approach into your broader trading plan.
