Summary

Cash and carry arbitrage pairs a spot purchase with a futures sale, aiming to capture the price gap between the two markets rather than betting on price direction. 

Key Takeaways

• The strategy pairs a spot purchase with a futures sale on the same asset.
• Returns generally depend on the basis rather than on overall market direction.
• Cost of carry means financing and the opportunity cost of capital, plus storage and insurance where the asset is a physical commodity. 
• A narrow basis can leave little room for profit once costs are factored in.
• Carrying costs generally increase the longer the position remains open.

Introduction

Cash and carry arbitrage is one of the more structured strategies available to investors working across spot and futures markets in India. Rather than betting on which direction an asset’s price will move, the strategy focuses on the gap between the spot and futures price of the same asset. This article covers how the strategy works, along with its potential benefits and risks.

What is Cash and Carry Arbitrage?

An investor buys an asset in the spot market and, at the same time, sells a futures contract on that same asset. This combination is the simplest kind of cash and carry arbitrage. The objective is to lock in the difference between the two prices, known as the basis. This method is usually used in the commodity and equity derivatives market, including markets regulated by SEBI in India, like NSE and MCX trading.

Futures prices usually trade above spot prices. This is largely because of the cost of carry, which represents the price of holding an asset until a contract expires. For a physical commodity that means storage, insurance and financing; for equities, financing alone. 

It also reflects the opportunity cost of capital. Traders sometimes call this pattern contango; futures trading above the current spot price. The opposite scenario, where futures trade below the spot price, is known as backwardation. Under these conditions, cash and carry arbitrage is generally ineffective. 

Why Should You Consider the Cash and Carry Arbitrage Strategy?

Cash and carry arbitrage tends to carry less risk than a directional bet, largely because the investor is holding two offsetting positions rather than betting on which way a single price will move. Losses on one position are often partly offset by gains on the corresponding position. 

The strategy nevertheless involves real risks: execution slippage between the two legs, margin calls on the futures side, and a basis that narrows before you can close. It may nevertheless appeal to investors seeking market-neutral returns who have the capacity to manage execution and margin requirements. 

How Does Cash and Carry Arbitrage Work?

The strategy is typically two-fold and simultaneous:

• The investor purchases the underlying asset in the spot market.
• The investor sells a futures contract on that same asset, typically with a fixed expiry date.

The two prices converge as expiry approaches, which is what makes the locked-in basis realisable. At expiry, the investor would have the choice of either delivering the asset against the futures position or closing both legs, depending on the contract and the exchange rules. The profit is the basis — futures selling price minus spot buying price; less the cost of carry. 

Executing both legs simultaneously is an important consideration. If the time of purchase on the spot market and the sale of the futures contract are different, the trade is not hedged and changes in prices during that period can reduce the expected return. Tight monitoring of margin requirements on the futures leg is also required. The total position is designed to offset itself, but a sharp price swing before expiry can cause a margin call. 

Breaking Down Cash and Carry Arbitrage Strategy

Several factors influence the profitability of a cash and carry trade.

Component	What it Represents
Spot price	The current market price of the underlying asset
Futures price	The agreed price for delivery at a future date
Cost of carry	Storage, insurance, and financing costs incurred while holding the asset
Basis	The difference between the futures price and the spot price

The futures price needs to trade sufficiently above the spot price to cover the cost of carry and still generate a potential profit. When the basis is narrow, brokerage and taxes may eliminate the expected profit. 

An Example of Cash and Carry Arbitrage

For example, assume an investor buys gold in the spot market at ₹1,41,000 per 10 grams and, simultaneously, sells a three-month gold futures contract at ₹1,44,400. The basis is therefore ₹3,400. If carrying the gold for those three months, storage and financing included, costs roughly ₹2,700, the investor is left with a potential gain of around ₹700 per 10 grams 

This example is for illustration only. It leaves out taxes, exchange fees, and any price movement that might happen before expiry. Real outcomes shift with market conditions and the specific terms of the contract in question.

What Are the Benefits of Cash and Carry Arbitrage?

1. Reduced dependence on market direction: The offsetting positions mean returns are not closely tied to whether the broader market goes up or down.
2. Defined return potential: The entry prices are known when the trade is opened, so the likely outcome can often be worked out ahead of time, cost of carry and transaction costs included.
3. Suitability for larger portfolios: Investors with sufficient liquidity for both the spot purchase and futures margin can deploy unallocated capital into structured arbitrage opportunities. 
4. Structured exit: The contract expiry provides a defined point at which the position can typically be closed or settled.

How Does a Reliable Platform Assist in Cash and Carry Arbitrage?

Execution of this strategy usually needs access to the spot and futures markets and tools to track the basis movements. Utilizing a trading platform that integrates both spot and derivatives markets streamlines order execution. It allows a trader to estimate the cost of carry and place orders in both markets with the smallest lag between the two legs.

Margin rules, contract details, and expiry dates differ between exchanges and asset classes. A platform like Jainam provides this information in a clear manner and also offers research or advisory support along with it, which assists investors in evaluating the viability of a specific arbitrage opportunity.

Conclusion

This strategy is typically more dependent on the relationship between spot and futures prices than on the direction of the market as a whole. It may appeal to investors seeking a more structured way to generate returns. But the costs and risks involved should still be carefully considered before committing any capital. Reviewing the cost of carry, transaction costs and margin requirements can help you make more informed decisions before you enter a trade.
