Perpetual Futures
What Are Perpetual Futures?
Perpetual futures, often referred to as “perps,” are a fundamental trading instrument in the digital asset market. Unlike traditional futures contracts, which have a specific settlement date where the contract expires and the underlying asset must be delivered, perpetual futures can be held indefinitely. This unique characteristic allows you to maintain exposure to an asset’s price movements over long periods without needing to roll over your position to a new contract.
These contracts do not involve the direct purchase or ownership of the underlying asset. Instead, they are synthetic products that track the asset’s price. Traders use these contracts to enter long positions if they expect the price to rise, or short positions if they expect a decline.
How Do Perpetual Futures Work?
The primary challenge of a perpetual contract is ensuring its price stays aligned with the actual market price of the asset, known as the spot price. Since there is no expiration date to force settlement, perpetual futures use a mechanism called the funding rate.
The funding rate is a series of regular payments made between long and short traders. When the perpetual contract price is higher than the spot price, the funding rate is positive, meaning longs pay shorts. Conversely, if the contract price is lower than the spot price, the funding rate is negative, and shorts pay longs. This continuous exchange of fees creates a financial incentive for traders to move the contract price back toward the spot price.
Leverage and Liquidation Risks
One of the most significant features of perpetual futures is the ability to use leverage. Leverage allows you to open a position much larger than your initial collateral, known as the margin. For example, with 10x leverage, a $1,000 margin allows you to manage a $10,000 position. While this can amplify potential profits, it equally magnifies potential losses.
This leads to the risk of liquidation. To explain, perpetual contracts are highly sensitive to price volatility. If the market moves against your position and your margin falls below a specific threshold (the maintenance margin), the exchange will automatically close your position. In these scenarios, the trader loses their initial collateral.
Due to the lack of an expiration date and the intensity of crypto market swings, managing risk through stop-loss orders and careful margin allocation is a critical component of trading perpetuals.
