What Are Perpetual Futures? A Complete Guide to Perpetual Contracts in Crypto Trading

The crypto markets are always on in perpetual mode, and traders need instruments that will be able to keep pace. The best such instrument is perpetual futures—the perpetual legacy, sometimes used to describe perpetual swaps. Perpetual futures never expire like ordinary futures but give traders an uninterrupted market exposure in eternity and no rollover costs. 

This perpetual contracts guide will explain what they are and how they function. It delves into their mechanics and explains why it is crypto’s favourite derivative.

Key Takeaways

• Perpetuals never terminate and are therefore less restrictive than futures.  
• Leverage, margin requirements and funding rates are the mechanics by which it works.  
• Liquidity and flexibility on a 24/7 schedule transform them into the crypto market’s highest-volume traded derivative.

What Are Perpetual Futures?

Perpetual futures—or perpetual swaps in short form—constitute one of the most well-liked types of derivative contracts in cryptocurrency trades. Unlike other futures contracts whose life is prescribed by an expiration date, perpetual futures are not subject to an expiration date. 

Therefore, a trader can keep a position open until he is required to close it by running short of the necessary margin. Perpetuals are thus an ultra-versatile instrument in speculation and in hedging.

The key difference between perpetual futures and ordinary futures is the absence of an expiry. Ordinary futures entail settlement at a predetermined time, and this requires the trader to close or roll over their positions. Perpetual futures are in perpetual form and are always traded and never have settlement dates.

Perpetual futures prices are kept closely on course to the underlying spot market through the application of a system called funding rates, whereby on either side of the market, traders are paid or pay an infinitesimally small amount at frequent time intervals, depending on market conditions.

Perpetual contracts first appeared in the crypto market in 2016 by BitMEX. Since their release, they have evolved to become one of the highly liquid and sought-after digital asset trading products.

The popularity of perpetual contracts progressed in parallel with the overall growth of crypto derivatives and attracted retail and institutional market players in their quest for high-leverage plays and effective hedging products. Perpetual futures now dominate crypto derivatives markets and account for a considerable portion of spot prices per day on key exchanges.

Fast Fact

• Perpetual contracts were first launched in 2016 and now account for the majority of global crypto derivatives volume.

Core Mechanics of Perpetual Futures

Perpetuals are built on a few key mechanics—leverage, margin, and funding rates—that define how positions are opened and closed and how positions are valued. Successful trading in perpetual contracts depends on comprehension of these fundamentals.

Leverage

Leverage is the key to perpetual futures. It refers to the trader having the ability to control a huge position size in relation to the margin applied. For example, on 10× leverage, a $1,000 margin will open up a $10,000 position. Gains and losses are then calculated on the entire $10,000 and not on the applied margin. Gains therefore accumulate very fast—but so do losses.

The benefits of leverage are clear: it lets traders make more effective use of capital, diversify their existing portfolios, and be less limited when entering and exiting positions. 

The disadvantage is equally profound. A slight price movement in an unfavourable manner on a position will have you liquidated once your margin falls below the required levels. High leverage is a good thing in experienced hands alone; it requires strict discipline and risk management.

Margin Requirements

Margin is the money you invest to establish a leveraged position. When entering a trade for the first time, you invest an initial margin based on the size of your position and the leverage. After opening a trade, in addition to the initial margin used to open the position, a maintenance margin is required to ensure that there are always enough funds to maintain an open position.

Suppose the equity in the account falls below the maintenance margin. In that case, the exchange will activate the liquidation process and close some or all of your position to prevent making your balance negative. 

Exchanges will tend to invoke a “mark price”—a fair-weighted price reference—to base their margin calls on, this to protect traders from surreptitious manipulations or uncommon surges in prices.

There are also two ways to margin: isolated, in which the margin is tied to each individual position, and cross, in which your total account balance funds all trades. Isolated margin limits your risk to just one position, while cross margin is less restrictive, but simultaneously puts at risk an entire account if trades become unsuccessful.

Funding Rates

Since perpetual contracts never end, their prices need a means to stay tied to the underlying spot market. This is achieved through funding rates, minimal periodic payments paid directly by long and short traders. When the perpetual contract price is higher than spot, funding is positive and longs pay shorts. When the contract is lower than spot, funding turns negative and shorts pay longs.

Funding is essential in keeping perpetuals in alignment with spot prices. If the contract price is too expensive, it is costly to carry longs and requires traders to sell, lowering the price. If the price is too low and below the spot, shorts are paid funding, and it is costly to carry a short position, causing traders to buy, which in turn raises the price.

For traders, funding is never just a technical fine-tune—it has direct profitability consequences. Even if the market price itself is undisturbed, having an enormous leveraged position in a market with consistently positive funding will eat into returns. 

Traders on the right side of funding are then able to earn a steady return just by staying in the trade. Perpetual futures success is as much an exercise in reading price action as it is in maintaining a keen eye on funding dynamics.

Key Differences from Traditional Futures

Despite perpetual futures being highly akin to standard futures in several respects, certain key differences characterise them. 

From the absence of expiry dates to special settlement procedures and broader applications, these differences are the reason why perpetuals are now the crypto market's favourite derivative.

Expiration vs. Perpetual Rollover

The simplest distinction found in traditional futures and perpetual contracts is in their expiry date. Regular futures come with a defined maturity, like monthly or quarterly, and will be settled upon the arrival of the date. Traders wishing to maintain a position after expiry will be forced to roll it over to a new contract, usually incurring other costs and possible slippage.

Perpetual futures never expire. There is no end date. Positions may be left open indefinitely, so long as margin requirements are maintained. This is preferable in certain long-term hedges and short-term short- and long-position speculation trades, in which traders do not risk having their strategy messed up by contract rollovers.

Settlement Mechanisms

Traditional futures settle at expiration, usually in cash or through physical delivery, depending on the market. For example, a quarterly Bitcoin futures contract might be cash-settled against a reference index when it expires. The settlement event is a critical point that can cause volatility as traders close or roll positions.

Perpetual contracts avoid this by using funding rates as a continuous settlement procedure. Instead of a huge expiry event, longs and shorts construct and accept regular small payments to one another, whose perpetual price is closely matched to the spot market. This continuous correction reduces the pressure of an expiry day, allowing for freer, uninterrupted trading.

Use Cases: Hedging, Speculation, and Arbitrage

Traditional futures and perpetual contracts apply to hedging, speculation, and arbitrage, but perpetuals offer special benefits. Hedgers, such as miners or longholders, can ensure price coverage without having to roll contracts each month. Speculators can maintain highly leveraged positions in an always-open 24/7 market with ample liquidity.

Perpetuals are also appealing to arbitrageurs due to their funding method. Traders can form basis trades—long spot/short perp or vice versa—to capture yield with limited directional exposure when funding rates are positive or negative to an extreme degree. The arbitrage is less rigid than in standard futures markets, where arbitrage is often built around certain expiry periods.

Despite perpetual futures being highly akin to standard futures in several respects, certain key differences characterise them. 

From the absence of expiry dates to special settlement procedures and broader applications, these differences are the reason why perpetuals are now the crypto market's favourite derivative.

Why Perpetual Futures Dominate Crypto Trading?

Perpetuals are now the linchpin within the crypto derivatives market. Their unique structure, perpetual availability, and suitability for each differing style of trading are reasons why they attract higher volume and interest than virtually every other digital finance product.

Popularity Among Retail and Institutional Traders

Perpetuals have quickly become crypto's fastest-traded derivative and are appealing to institutions and retail traders. For retail participants, perpetuals' uncomplicated mechanics and the convenience of purchasing and selling contracts without having to worry about expiry are appealing. 

For institutions, their standardised form, deep liquidity pools, and effectiveness in hedging prominent spot positions are appealing. Their concurrent popularity has established perpetuals as the clear leader in digital assets' derivatives.

High Liquidity and 24/7 Accessibility

Contrary to conventional futures markets that are only transacted at limited hours and are closed on weekends, crypto perpetuals are always active. This continuity in 24/7 accessibility is best suited to worldwide markets, where information and price movements can come at any time. 

The volume of transactions in perpetual contracts is likewise huge and converts into high liquidity, lower spreads, and efficient execution even on big trades. For the trader, it results in less slippage, consistent order matching and freedom to come in or cover positions at will.

Flexibility in Risk Management and Hedging

Perpetual futures also dominate because risk management is done very efficiently. Downside risk is reduced on longs by using short perpetual positions, so their underlying assets never have to be sold. Traders are then quickly turning risk up or down with leverage, depending on market conditions. 

For speculation, perpetuals then at least give traders a choice to profit off prices rising or falling, so a greater range of strategies over spot simple trading are available.
