Cost of Carry

Cost of Carry

The “Cost of Carry” is a fundamental concept in financial markets, especially crucial for understanding derivatives, particularly futures contracts and options trading. It represents the net cost of holding an asset over a period of time. In the context of crypto futures, understanding the cost of carry is essential for profitable trading strategies and accurate price discovery. This article aims to provide a comprehensive, beginner-friendly explanation of this important concept.

Defining Cost of Carry

At its core, the cost of carry is the difference between the costs of holding an asset and the income earned from that asset. These costs and income components can vary significantly depending on the asset in question. For a physical commodity like gold or oil, the costs might include storage, insurance, and transportation. For a financial asset like a stock or cryptocurrency, the costs could include interest paid on borrowed funds used to purchase the asset, as well as potential opportunity cost of capital. The income, conversely, could be dividends for stocks, or interest earned on cash holdings.

In the realm of crypto futures, where the underlying asset is often a cryptocurrency like Bitcoin or Ethereum, the cost of carry is slightly different. It primarily focuses on the difference between the cost of funding the position and any yield earned on the underlying asset. Because most cryptocurrencies don't pay dividends or interest, the "income" component is often minimal or absent.

Components of Cost of Carry in Crypto

For crypto futures, the main components of the cost of carry are:

• Funding Costs: This is the interest expense incurred when borrowing funds to purchase the underlying cryptocurrency. Even if you purchase crypto with existing capital, there's an opportunity cost – the return you could have earned by investing that capital elsewhere.
• Storage Costs: While not a physical storage cost like with commodities, the equivalent in crypto is the security cost of holding the underlying asset – the risk of loss through hacking or theft, which traders implicitly factor into their pricing.
• Exchange Fees: Trading fees on the spot market to hedge or rebalance positions contribute to the overall cost.
• Insurance Costs: Although less common, some platforms offer insurance for held assets, adding to the cost.

Contango and Backwardation

The cost of carry plays a significant role in determining the relationship between the spot price of an asset and its futures price. This relationship manifests as either contango or backwardation.

• Contango: This occurs when futures prices are higher than the current spot price. This is the most common scenario. In contango, the cost of carry is *positive*. Traders are willing to pay a premium for future delivery because of the costs associated with holding the asset. The further out the futures contract expiration date, the higher the price typically is in contango. Technical analysis can help identify these patterns.
• Backwardation: This occurs when futures prices are lower than the current spot price. This is less common and often signals a supply shortage or strong demand in the immediate future. In backwardation, the cost of carry is *negative*. Traders are willing to accept a discount for future delivery, potentially due to convenience yield (e.g., immediate availability of a commodity) or expectations of a price decline. Volume analysis can provide clues about backwardation.

Impact on Crypto Futures Trading

Understanding the cost of carry is crucial for several reasons:

• Futures Pricing: The cost of carry directly influences the price of futures contracts. Accurate cost of carry calculations are key for arbitrage opportunities.
• Trading Strategy Selection: Different trading strategies perform better in contango versus backwardation. For example, carry trades aim to profit from the cost of carry.
• Roll Yield: When a futures contract approaches its expiration date, traders must "roll" their position to a later-dated contract. In contango, this roll typically results in a loss (negative roll yield) as you're buying a more expensive contract. In backwardation, it results in a gain (positive roll yield). Position sizing is important here.
• Funding Rate Arbitrage: In perpetual swaps, which are similar to futures but don't have an expiration date, the funding rate adjusts to keep the price close to the spot price, effectively reflecting the cost of carry. Perpetual Swaps are a key component of crypto derivatives.
• Implied Repo Rate: The difference between the spot and futures price can be used to calculate an implied repo rate, a measure of the cost of borrowing the underlying asset.

Calculating Cost of Carry

A simplified calculation of the cost of carry for a crypto future is:

Cost of Carry = (Futures Price – Spot Price) / Spot Price

This gives a percentage representing the annualized cost of carrying the asset. Remember to consider the time to expiration of the futures contract.

Advanced Considerations

• Convenience Yield: While rare in crypto, this is the benefit of holding a physical commodity (e.g., having oil readily available during a supply disruption).
• Market Sentiment: Market psychology can influence futures prices and deviate from theoretical cost of carry calculations.
• Liquidity: Low market liquidity can widen the spread between spot and futures, affecting the cost of carry.
• Volatility: Volatility analysis is crucial, as higher volatility generally increases the cost of carry due to increased risk.
• Basis Risk: The risk that the relationship between the spot and futures price will change unexpectedly. Hedging strategies can help mitigate basis risk.
• Correlation: Understanding the correlation between different crypto assets can inform cost of carry calculations.
• Order Flow: Monitoring order flow can provide insights into market sentiment and potential shifts in cost of carry.
• Time Decay: Theta is a key factor in options, representing the rate of time decay, which impacts the cost of carry.
• Gamma: Gamma represents the rate of change of delta, and can significantly affect the cost of carry for options positions.
• Vega: Vega measures the sensitivity of an option's price to changes in volatility, impacting the overall cost of carry.
• Delta: Delta is the rate of change of an option’s price with respect to a change in the underlying asset’s price, influencing cost of carry considerations.

Conclusion

The cost of carry is a vital concept for anyone involved in trading crypto derivatives. By understanding its components, how it affects futures pricing, and its implications for different trading strategies, traders can make more informed decisions and improve their profitability. Ignoring the cost of carry can lead to significant losses, particularly when rolling futures contracts or engaging in long-term holding strategies.
