In the fast-moving world of finance, new tools are constantly emerging to help traders maximize returns. Among these, perpetual futures have gained significant traction—especially in the cryptocurrency space—offering a unique blend of flexibility, leverage, and continuous market exposure. But how exactly do they work, and what makes them different from traditional futures? Let’s break it down.
What Are Futures Contracts?
Before diving into perpetual futures, it’s important to understand the foundation: futures contracts.
A futures contract is a standardized agreement to buy or sell an asset—such as a commodity, stock index, or cryptocurrency—at a predetermined price on a specific future date. These contracts are traded on regulated exchanges and are commonly used for both speculation and hedging.
For example, a farmer might use a futures contract to lock in the price of wheat months in advance, protecting against price drops. Conversely, a trader might buy an oil futures contract betting that prices will rise, aiming to profit from the difference.
Once the contract reaches its expiration date, it’s settled either through physical delivery of the asset or cash settlement. However, traders often close their positions before expiry to avoid taking delivery.
Introducing Perpetual Futures Contracts
Perpetual futures are a modern evolution of traditional futures—designed without an expiration date. First conceptualized by economist Robert Shiller in 1992 and later popularized by BitMEX in 2016, they’ve become a cornerstone of crypto derivatives trading.
Unlike standard futures, perpetual contracts can be held indefinitely, allowing traders to maintain long or short positions for as long as they wish—provided they meet margin requirements and avoid liquidation.
This makes them ideal for traders who want ongoing exposure to an asset’s price movements without the hassle of rolling over expiring contracts.

The Funding Rate Mechanism
One of the most critical features of perpetual futures is the funding rate—a mechanism that ensures the contract price stays closely aligned with the underlying asset’s spot price.
Here’s how it works:
- Every 8 hours, a funding payment is exchanged between long and short position holders.
- If the perpetual contract trades above the spot price (a state known as premium), longs pay shorts. This incentivizes selling pressure, bringing the price back down.
- If the contract trades below the spot price (discount), shorts pay longs, encouraging buying activity to push the price up.
The funding rate is determined by two components:
- Interest rate – Typically minimal or zero in crypto markets.
- Premium index – Reflects the difference between the perpetual contract price and the spot index price.
This regular rebalancing prevents prolonged deviations and maintains market efficiency.
Initial and Maintenance Margin
To open a perpetual futures position, traders must deposit initial margin—a percentage of the total position value serving as collateral. This enables leverage, allowing traders to control larger positions with less capital.
For example, with 10x leverage, a $1,000 margin can control a $10,000 position.
However, markets move quickly. To prevent defaults, exchanges enforce a maintenance margin—the minimum equity required to keep a position open. If losses reduce the account balance below this threshold, the position may be automatically liquidated.
Profits and losses are marked to market in real time, meaning your equity updates continuously based on current prices.
Perpetual Futures vs. Traditional Futures
| Feature | Traditional Futures | Perpetual Futures |
|---|---|---|
| Expiration Date | Yes | No |
| Settlement | Physical or cash at expiry | Cash-settled, no expiry |
| Carrying Costs | Storage, insurance, financing | None |
| Price Convergence | At expiry | Continuous via funding rate |
While traditional futures rely on natural convergence at expiration, perpetuals use active mechanisms like funding rates to maintain alignment with spot prices—offering greater flexibility and reduced operational friction.

Advantages of Perpetual Futures
- High Leverage: Amplify potential returns with leveraged positions (e.g., 20x, 50x, or even 100x).
- No Expiry Hassle: Avoid the need to roll over contracts manually.
- Hedging Flexibility: Protect spot holdings against downside risk with offsetting short positions.
- Liquidity: Major perpetual markets (like BTC/USD) often see billions in daily volume, enabling fast execution.
Risks and Challenges
Despite their benefits, perpetual futures come with notable risks:
- High Volatility & Liquidation Risk: Leverage magnifies both gains and losses. A sharp price move can trigger liquidation.
- Funding Costs: Holding long positions during bullish markets may result in recurring payments to short holders.
- Complexity: Understanding funding rates, margin mechanics, and leverage requires education.
- Limited Regulation: Many crypto perpetual markets operate in unregulated environments, increasing counterparty risk.
Popular Trading Strategies
1. Speculative Trading
Traders use leverage to bet on price direction—going long if they expect prices to rise or short if they anticipate a drop. High liquidity and tight spreads make perpetuals ideal for short-term speculation.
2. Arbitrage
Exploit price differences between perpetual contracts and spot markets (or across exchanges). For instance:
- Buy BTC on the spot market.
- Simultaneously short BTC perpetuals.
- Profit when prices converge.
This strategy carries lower directional risk but requires precise execution.
3. Hedging
Investors holding cryptocurrencies can hedge against downturns by opening short perpetual positions. If the market drops, gains from the short position offset losses in their spot portfolio.
Frequently Asked Questions (FAQ)
What are perpetual futures in crypto?
Perpetual futures are derivative contracts that allow traders to speculate on cryptocurrency prices without an expiration date. They use a funding rate to stay aligned with spot prices.
How do funding rates affect my position?
If you hold a long position when funding is positive, you pay shorts. If negative, you receive payments. These periodic transfers help stabilize pricing.
Can I hold perpetual futures forever?
Yes—there’s no expiration. However, you must maintain sufficient margin and may incur funding costs over time.
Are perpetual futures riskier than spot trading?
Yes. Leverage increases both profit potential and risk of loss. Poor risk management can lead to liquidation.
What happens during liquidation?
If your margin falls below the maintenance level, your position is automatically closed to prevent further losses. Some platforms charge a liquidation fee.
Which assets offer perpetual futures?
Major cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and Solana (SOL) are widely available. Some platforms also offer perpetuals on indices and altcoins.

Final Thoughts
Perpetual futures have revolutionized digital asset trading by combining the power of leverage with unlimited holding periods and dynamic price alignment. Whether you're hedging a portfolio, speculating on volatility, or exploring arbitrage opportunities, they offer powerful tools for active traders.
However, success requires more than just access—it demands knowledge, discipline, and robust risk management. Start small, understand the mechanics, and never risk more than you can afford to lose.
With the right approach, perpetual futures can be a valuable addition to your trading toolkit—offering flexibility and opportunity in one of the most dynamic markets today.
