What Is Cash-and-Carry and How to Use It for Arbitrage
Cash-and-carry is one of the best-known arbitrage concepts in derivatives markets. In simple terms, it refers to a strategy that takes advantage of the price gap between an asset in the spot market and the price of a futures contract linked to that same asset. When the futures contract trades at a premium that is larger than the cost of holding the asset until expiry, traders may look at that difference as a potential arbitrage opportunity.
In crypto markets, this idea is often discussed under the broader label of basis arbitrage. The strategy focuses less on predicting whether Bitcoin, Ethereum, or another digital asset will rise or fall, and more on how the spot price and futures price relate to each other over time. That is why cash-and-carry is often described as market-neutral in design. The goal is not to bet on direction, but to capture the narrowing of the gap between the two markets.
This article explains what cash-and-carry means, how basis works, why spot and futures prices converge, how the strategy is executed, and what risks traders should understand before using it.
Understanding the idea behind cash-and-carry
To understand cash-and-carry, you first need to look at two different markets.
The spot market is where an asset is bought or sold for immediate settlement. If you buy Bitcoin on the spot market, you are purchasing the asset at the current market price.
The futures market is different. Instead of buying the asset itself, traders buy or sell a contract that reflects the asset’s value at a future date. That contract can trade above or below the spot price depending on market conditions.
The difference between the futures price and the spot price is known as the basis.
Basis = Futures Price - Spot Price
This basis is the foundation of cash-and-carry trading. When futures trade above spot, the market is in contango. When futures trade below spot, the market is in backwardation. In many cases, cash-and-carry opportunities are associated with contango because the futures contract is trading at a premium.
That premium may exist for several reasons, including demand for leverage, hedging activity, and the cost of carrying the asset until the contract expires. If the premium becomes large enough, traders may try to lock in that spread through arbitrage.
Why spot and futures prices converge
A key principle behind cash-and-carry is convergence. As a futures contract approaches expiry, its price should move closer to the spot price of the underlying asset.
This happens because a futures contract cannot remain permanently disconnected from the cash market at maturity. Once expiry arrives, the contract is tied directly to the value of the underlying asset or the exchange’s settlement process. If a large mismatch remained at maturity, traders would rush to exploit it, and that arbitrage activity would help close the gap.
This predictable narrowing of the basis is what makes cash-and-carry attractive. The trader is trying to benefit from the fact that the futures premium should decline as expiry gets closer, provided the position is structured properly and costs are controlled.
How the cash-and-carry strategy works
The cash-and-carry trade follows a simple structure, even though the execution can become more complex in practice.
A trader identifies that the futures price of an asset is trading above the spot price by a margin that appears attractive. The trader then buys the asset in the spot market and, at the same time, sells the futures contract on that same asset.
The spot position is the long leg of the trade. The futures short position is the hedge. If the market price rises, the spot holding gains value while the short futures position loses value. If the market falls, the spot holding loses value while the short futures position gains value. Because of this structure, the strategy is designed to reduce directional exposure.
The intended return comes from the basis premium rather than from correctly predicting where the market will move next.
At expiry, the futures price and the spot price should converge. If the basis narrows as expected, the trader can close both positions and potentially keep the difference, after subtracting fees and other relevant costs.
A simple example
Imagine Ethereum (ETH) is trading at $2,300 in the spot market, while Bitcoin (BTC) is trading at $68,000. Now assume a three-month BTC futures contract is trading at $70,500.
That means the basis on Bitcoin is $2,500, calculated as:
Basis = Futures Price - Spot Price
Basis = $70,500 - $68,000 = $2,500
A trader using a cash-and-carry strategy could buy 1 BTC in the spot market at $68,000 and, at the same time, open a short position in the BTC futures contract at $70,500. The trader would then hold both positions until the contract approaches expiry.
If the futures premium narrows as the contract matures, the trader may be able to capture much of that $2,500 spread, after subtracting trading fees, funding costs, margin requirements, and any other related expenses.
This example highlights the core idea behind cash-and-carry. The trader is not depending on Bitcoin to rise or fall in price. Instead, the strategy is based on the relationship between the spot price and the futures price, and on the expectation that the gap between the two will narrow over time.
Why the strategy is described as market-neutral
Cash-and-carry is often called market-neutral because it is not based on a bullish or bearish view of the underlying asset. The trader is hedged through opposite positions in two linked markets.
That does not mean the strategy is risk-free. It simply means the trader is attempting to reduce exposure to outright price direction. If the hedge is properly sized, gains on one side of the trade may offset losses on the other side.
The real objective is to capture price convergence. In other words, the trader wants to benefit from the futures premium narrowing over time rather than from market momentum.
This distinction matters because many people hear the word arbitrage and assume the result is guaranteed. In reality, even a structurally neutral trade can still involve execution risk, funding risk, margin pressure, and exchange-related risk.
The role of cost of carry
The basis does not exist in a vacuum. Futures can trade above spot for valid reasons, and one of the most important is the cost of carry.
Cost of carry refers to the economic cost of holding an asset until the futures contract expires. In traditional markets, that can include financing, storage, insurance, and opportunity cost. In crypto markets, the components may look slightly different, but capital costs, exchange fees, custody arrangements, and margin still matter.
This is why not every positive basis is an arbitrage opportunity. A futures premium can be justified if it reflects the true cost of holding the asset over time. Traders need to compare the size of the basis with all relevant costs before deciding whether the trade is attractive.
A spread that looks large at first glance may become much smaller after including fees, slippage, collateral requirements, and trading friction.
Using cash-and-carry in crypto markets
In digital asset markets, basis arbitrage has become one of the more widely discussed strategies because crypto often has active spot and derivatives markets trading side by side. Traders can compare the current price of an asset on the spot market with the price of dated futures or perpetual contracts and look for dislocations.
The basic cash-and-carry structure in crypto usually follows the same logic as in traditional markets. The trader buys the digital asset in the spot market and shorts a futures contract. If the futures contract is trading at a sufficient premium, the trade may offer a way to capture that spread as the contract moves toward expiry.
Crypto markets, however, also introduce specific considerations. Exchange risk, liquidation mechanics, collateral management, and high volatility all play a larger role than many newcomers expect. A structurally neutral trade can still face pressure if the short leg is leveraged and margin is not managed carefully.
Cash-and-carry with perpetual contracts
Traditional cash-and-carry is usually linked to dated futures contracts because those contracts have a clear expiry date and a natural convergence point. In crypto markets, however, perpetual contracts are also widely used.
Perpetual futures do not expire. Instead, they stay anchored to the spot market through a mechanism known as the funding rate. If the perpetual market is heavily long, long holders may pay funding to short holders. If the market is heavily short, the flow may reverse.
This creates a variation of the basis trade. A trader may buy the asset on the spot market and short the perpetual contract, aiming to collect funding payments while keeping directional exposure limited.
Although this is related to cash-and-carry in concept, it is not identical to a dated futures arbitrage. The trade depends on funding rate dynamics rather than a fixed expiry-driven convergence. That means the outcome can be less predictable and may change more quickly with market sentiment.
Why traders use this strategy
The appeal of cash-and-carry comes from its structure. Instead of relying on a directional forecast, the trader is focusing on market mechanics. In theory, that can make the strategy more systematic than outright speculation.
Some traders use it to seek relative value opportunities. Others use it as a hedged way to engage with crypto market structure. In more developed markets, basis trading is also part of how professional participants keep spot and derivatives pricing aligned.
The strategy can also be useful for understanding how markets function. Even traders who never execute a cash-and-carry trade can learn a great deal from watching basis levels, futures premiums, and the way those premiums behave in different market conditions.
The main risks traders should understand
Although cash-and-carry is often presented as structured and neutral, it still carries meaningful risk.
One of the biggest risks is liquidation and margin pressure. In crypto, the short futures leg may involve leverage. If the market moves sharply upward and the position is not adequately collateralized, the futures leg can face liquidation even though the overall strategy is hedged in concept.
There is also fee risk. Spot trading fees, futures execution fees, and bid-ask spreads all reduce the net result. A trade that looks profitable before costs may not remain attractive after all expenses are included.
Another important issue is exchange and operational risk. Cash-and-carry in crypto often depends on the stability of the platform being used, the reliability of order execution, and the handling of collateral and settlement. Even a mathematically sound trade can become problematic if operational conditions are poor.
Then there is volatility risk. Crypto assets are highly volatile, and that can create stress even in market-neutral setups. Short-term price swings may trigger margin calls, force position adjustments, or make it harder to maintain the trade until the intended convergence takes place.
Tax treatment also matters. Profits from crypto transactions and arbitrage activity may be taxable, but the exact treatment depends on a trader’s circumstances and the applicable rules in their jurisdiction. That means tax should be treated as part of the overall evaluation rather than as an afterthought.
Spot trading, futures trading, and basis arbitrage
It is common for traders to compare spot trading, futures trading, and basis arbitrage as if they were substitutes, but they serve different purposes.
Spot trading offers direct ownership of the asset. It is simple to understand, but the trader remains fully exposed to market moves.
Futures trading gives access to leverage and hedging tools. It can be useful for managing exposure, but it also introduces liquidation risk and more complex position management.
Basis arbitrage combines elements of both. By holding the asset in spot and taking the opposite side in futures, the trader is trying to reduce directional exposure and focus on the spread between the two markets.
That makes basis arbitrage less about predicting price and more about evaluating market structure.
Practical points before using cash-and-carry
Before using any version of cash-and-carry, traders need to look beyond the headline spread. A premium is only meaningful if it remains attractive after costs, execution, and risk controls are considered.
The first question is whether the spot and futures positions are properly matched in size. The second is whether the basis is large enough after fees and other friction. The third is whether the account can withstand volatility and margin requirements during the holding period.
It is also important to understand the specific contract involved. Dated futures and perpetual contracts do not behave the same way. Settlement rules, funding mechanics, and exchange margin policies can all change the trade’s economics.
A strategy that looks clean in theory requires careful management in practice.
In Conclusion
Cash-and-carry is one of the clearest ways to understand arbitrage in modern markets. It is built around a simple idea: when futures trade above spot by more than the cost of carrying the asset, the gap may create an opportunity.
In crypto markets, this concept appears through basic arbitrage and, in some cases, funding-rate-based strategies using perpetual contracts. The structure is often described as market-neutral because it aims to reduce outright price exposure and focus instead on convergence between markets.
Even so, cash-and-carry should not be treated as effortless or risk-free. Fees, liquidation risk, exchange risk, volatility, and operational details can all affect the final outcome. The strategy is best understood as a disciplined way of trading market structure rather than a shortcut to easy profit.

Frequently Asked Questions
1. What is cash-and-carry in simple terms?
Cash-and-carry is an arbitrage strategy where a trader buys an asset in the spot market and sells a futures contract on the same asset to try to profit from the price gap between the two.
2. What is basis in cash-and-carry trading?
Basis is the difference between the futures price and the spot price. It is usually calculated as:
Basis = Futures Price - Spot Price
This price gap is the main factor traders watch when evaluating a cash-and-carry opportunity.
3. How does cash-and-carry arbitrage work?
The strategy works by buying the asset in the spot market and simultaneously opening a short futures position. If the futures premium narrows as expiry approaches, the trader may be able to capture that spread after costs.
4. Is cash-and-carry a risk-free strategy?
No, it is not risk-free. Although it is designed to reduce directional market exposure, traders can still face funding costs, margin pressure, liquidation risk, execution issues, and exchange-related risks.
5. Why do futures and spot prices converge at expiry?
As a futures contract gets closer to maturity, its price moves closer to the spot price because the time element disappears. This convergence is what makes cash-and-carry possible.
6. What is the difference between cash-and-carry and basis arbitrage?
Cash-and-carry is a type of basis arbitrage. Basis arbitrage is the broader concept of trading the price difference between spot and derivatives markets, while cash-and-carry specifically involves buying spot and selling futures.
7. Can cash-and-carry be used in crypto markets?
Yes, cash-and-carry is commonly discussed in crypto markets. Traders often use it with assets like Bitcoin or Ethereum by buying the asset on the spot market and shorting futures or perpetual contracts to try to benefit from the premium.
