Direct Answer
Reverse cash-and-carry arbitrage sells an asset short, invests the proceeds at the risk-free rate, and buys a futures contract on the same asset, locking in a profit when the futures price is below the asset's spot price plus the cost of carry, which is the mirror of the cash-and-carry trade used when futures are overpriced. It tends to work in markets where the futures are liquid and the asset is easy to borrow, such as stock indexes and Treasuries, and the profit is locked at entry. Borrow risk and recall risk; the arbitrage is only riskless if the short position can be maintained to delivery.

How Does Reverse Cash-and-Carry Arbitrage Work?
Reverse cash-and-carry arbitrage sells an asset short, invests the proceeds at the risk-free rate, and buys a futures contract on the same asset, locking in a profit when the futures price is below the asset's spot price plus the cost of carry, which is the mirror of the cash-and-carry trade used when futures are overpriced.
The rules:
- Compute the fair futures price as spot plus financing cost minus any income the asset pays over the period
- Enter when the futures trade below fair value by more than the costs of shorting, including the borrow fee
- Short the asset, invest the proceeds, buy the futures, and hold to delivery or convergence
- Confirm the asset can be borrowed for the full period; a recall ends the arbitrage early
Worked example. With spot at 100, a 5 percent rate and six months to delivery, the fair futures price is 102.50; if the futures trade at 101.00, shorting spot, investing the 100 and buying the futures locks in about 1.50 per unit before borrow costs. The inputs are illustrative numbers, not market data.
When it tends to work. It tends to work in markets where the futures are liquid and the asset is easy to borrow, such as stock indexes and Treasuries, and the profit is locked at entry.
When it fails. It fails when the asset is hard or expensive to borrow, when a dividend or coupon is larger than expected, and when the short is recalled before convergence.
Main risk. Borrow risk and recall risk; the arbitrage is only riskless if the short position can be maintained to delivery.
