Cash-and-carry arbitrage is a financial strategy involving the simultaneous purchase of an asset and the sale of futures contracts on that asset to exploit pricing inefficiencies. This method aims to lock in a risk-free profit by capitalizing on the price difference between the spot market and the futures market.
Mechanism of Cash-and-Carry Arbitrage
Step-by-Step Process
- Identify Pricing Discrepancy: The first step involves spotting a pricing inefficiency between the spot price of an asset and its corresponding futures price.
- Purchase the Asset: Buy the asset in the spot market where the price is lower.
- Sell Futures Contract: Simultaneously, sell a futures contract on the same asset where the futures price is higher.
- Hold Until Maturity: Hold the asset until the futures contract matures.
- Delivery: Deliver the asset to meet the futures contract. The profit is secured by the difference between the purchase price of the asset and the agreed futures price, minus any carrying costs.
Key Considerations
- Carrying Costs: The costs associated with holding the asset until contract maturity, including storage, insurance, and financing costs.
- Convergence: As the futures contract approaches its maturity, the futures price converges to the spot price.
Formula
The profit from a cash-and-carry arbitrage can be expressed as:
- \( F_t \) is the futures price at time \( t \)
- \( S_t \) is the spot price at time \( t \)
- \( C \) represents the carrying costs
Example of Cash-and-Carry Arbitrage
Consider an investor who identifies an arbitrage opportunity with gold, where the current spot price of gold is $1,800 per ounce, and a 3-month futures contract is priced at $1,850 per ounce. The carrying costs over the three months amount to $30 per ounce.
- Buy 100 ounces of gold in the spot market at $1,800 per ounce: Total cost = $180,000.
- Sell futures contracts for 100 ounces of gold at $1,850 per ounce: Total futures price = $185,000.
- Holding Costs: $30 per ounce for 100 ounces = $3,000.
- Net Profit Calculation:
$$ \text{Net Profit} = 185,000 - 180,000 - 3,000 = \$2,000 $$
Importance in Financial Markets
Arbitrage Opportunities
Cash-and-carry arbitrage plays a crucial role in maintaining market efficiency by eliminating pricing discrepancies between different markets. This strategy ensures that asset prices do not deviate significantly from their fair value, thereby fostering market stability.
Risk Factors
While considered low-risk, cash-and-carry arbitrage is not entirely free of risks. Factors such as interest rate changes, transaction costs, and the liquidity of the assets involved can affect the profitability of the strategy.
Comparison to Reverse Cash-and-Carry Arbitrage
Reverse Cash-and-Carry Arbitrage
Unlike cash-and-carry arbitrage, where the spot price is lower than the futures price, reverse cash-and-carry arbitrage occurs when the spot price is higher than the futures price. This situation involves short-selling the asset and simultaneously buying a futures contract.
