Cash-and-Carry-Arbitrage

Cash-and-carry arbitrage is a market-neutral strategy that involves taking a long position in an asset (usually a commodity or financial instrument) and simultaneously taking a short position in a futures contract on that same asset. The goal of the strategy is to exploit the difference between the spot price (the current market price) and the futures price of the asset to generate a risk-free profit at expiry. Cash-and-carry arbitrage is commonly used in the context of commodities like gold, oil, and stock indices, but it can also be applied to interest rate products and currencies.

Understanding Cash-and-Carry Arbitrage

The basic premise of cash-and-carry arbitrage is relatively straightforward. Here’s how it works:

1. Identify Discrepancy: The arbitrageur identifies a discrepancy between the spot price of an asset and its corresponding futures price.

2. Spot Market Long Position: The trader purchases the asset in the spot market, holding the physical commodity or asset.

3. Futures Market Short Position: Simultaneously, the trader sells a futures contract on the same asset. This lock in a price at which they will sell the asset in the future.

4. Carry Costs: Throughout the holding period, the trader bears the carrying costs, which include storage, insurance, and financing costs. These must be considered when calculating the arbitrage profit.

5. Delivery/Expiry: At the expiry of the futures contract, the trader delivers the asset to satisfy the futures contract, thus closing out both positions.

The profit from cash-and-carry arbitrage arises because the futures price typically includes a premium over the spot price due to the time value of money, storage costs, and the cost of carry. When the futures price is sufficiently higher than the spot price plus carry costs, arbitrage opportunities exist.

Key Components of Cash-and-Carry Arbitrage

Spot Price

The spot price is the current market price at which an asset is bought or sold for immediate delivery. In cash-and-carry arbitrage, the trader buys the asset at the spot price.

Futures Price

The futures price is the agreed upon price for future delivery of the asset through a futures contract. The futures price is typically higher than the spot price due to carrying costs and the time value of money.

Carry Costs

Carry costs encompass all expenses involved in holding the asset until the futures contract’s expiry. They can include:

• Storage Costs: For physical commodities, storage facilities may charge fees for holding the asset.
• Insurance Costs: Depending on the asset, insurance may be necessary to protect against loss or damage.
• Financing Costs: If the trader borrows money to buy the asset, the interest on the loan is part of the carry costs.
• Miscellaneous Costs: Any other incidental costs associated with holding the asset.

Arbitrage Profit

Arbitrage profit is the difference between the futures price and the sum of the spot price and carry costs. This can be expressed mathematically as:

[ \text{Arbitrage Profit} = \text{Futures Price} - (\text{Spot Price} + \text{Carry Costs}) ]

Practical Example

Consider an example involving gold:

1. A trader identifies that the current spot price of gold is $1,800 per ounce, while the futures price for delivery in three months is $1,850 per ounce.
2. The trader purchases 10 ounces of gold at the spot price, totaling $18,000.
3. The trader simultaneously sells a three-month futures contract for 10 ounces of gold at the futures price, yielding $18,500.
4. The carrying costs over three months (including storage, insurance, and financing) amount to $100.

At the expiration of the futures contract, the trader delivers the 10 ounces of gold to settle the futures position. The profit is calculated as follows:

[ \text{Arbitrage Profit} = \text{$18,500 (Futures Price)} - {\text{$18,000 (Spot Price)} + \text{$100 (Carry Costs)}} = $400 ]

Market Conditions Favoring Cash-and-Carry Arbitrage

Contango

Cash-and-carry arbitrage is most effective in a market condition known as contango, where the futures prices are higher than the spot prices. Contango generally occurs when there is an expectation that the price of an asset will rise over time or when carrying costs are significant. In such scenarios, futures contracts trade at a premium to spot prices, making arbitrage opportunities feasible.

Backwardation

In backwardation, futures prices are lower than spot prices. This condition can occur due to short-term supply shortages or strong immediate demand for the asset. While cash-and-carry arbitrage is less common in backwardation, a related strategy called reverse cash-and-carry arbitrage may be employed. This involves shorting the asset in the spot market and going long in the futures market.

Risk Management

Market Risks

Despite being considered a risk-free strategy, there are market risks to consider. Price fluctuations in the spot market prior to futures contract expiration could affect the potential profits or losses.

Basis Risk

Basis risk arises from the change in the difference between the spot and futures prices between the initiation and expiration of the arbitrage. Unanticipated changes can affect profits.

Liquidity Risk

Liquidity risk pertains to the ability to enter and exit positions in the spot or futures market without significantly impacting prices. If the markets are not sufficiently liquid, the trader might face difficulties.

Counterparty Risk

Counterparty risk in futures contracts stems from the possibility that the party on the other side of the contract may default on the agreement. Regulated exchanges mitigate this risk by acting as intermediaries.

Computational and Algorithmic Approaches

Algorithmic trading has enhanced the efficiency and scale at which arbitrage strategies like cash-and-carry can be executed. High-frequency trading (HFT) firms and quant traders develop complex algorithms to identify and exploit arbitrage opportunities across multiple markets and asset classes.

Examples of Algorithmic Approaches:

1. Price Discovery Algorithms: These algorithms continuously scan multiple exchanges and trading venues for price discrepancies between spot and futures prices.
2. Execution Algorithms: These are designed to carry out the trades in the spot and futures markets efficiently, minimizing market impact and maximizing execution speed.
3. Risk Management Algorithms: Algorithms that actively monitor carrying costs, market conditions, and other factors to mitigate risks associated with arbitrage trades.
