Why Do Perpetual Contracts Never Expire?

Why Do Perpetual Contracts Never Expire?

⏱ 6 min read

You’re trading Bitcoin futures, and suddenly you realize your contract has no expiration date. No rolling over, no settlement day — just an open position that keeps running. Sound familiar? That’s the beauty of perpetual contracts, and it’s why they’ve taken over crypto trading.

Perpetual contracts, or “perps,” are the most popular instrument on exchanges like Binance and Bybit. But why exactly don’t they expire? And how do they stay fair without a settlement date? Let’s break it down.

What Makes Perpetual Contracts Different From Traditional Futures?

Traditional futures contracts have a fixed expiration date — think monthly or quarterly settlements. When that date hits, the contract settles, and you either take delivery or roll into the next one. It’s a pain for traders who want to hold a position for weeks without worrying about rollover costs or slippage.

Perpetual contracts solve this by mimicking a spot market experience. They track the underlying asset’s price using a funding rate mechanism, which keeps the contract price in line with the spot price. No expiration means you can open a long or short position and keep it open indefinitely — as long as you have enough margin.

This design was pioneered by BitMEX in 2016 and quickly became the standard. Today, perps account for over 80% of all crypto derivatives volume, according to data from CoinDesk. The reason? Traders hate dealing with expirations. They want to focus on price action, not calendar management.

How Does the Funding Rate Keep Things Fair?

Without an expiration, how do you prevent the perpetual contract price from drifting away from the spot price? That’s where the funding rate comes in. It’s a periodic payment between long and short traders — not an exchange fee — that adjusts every 8 hours.

Here’s how it works in simple terms:

• When the perpetual price is above spot (contango): Longs pay shorts. This incentivizes shorts to enter, pushing the price down.
• When the perpetual price is below spot (backwardation): Shorts pay longs. This encourages longs to buy, pushing the price up.
• When the price matches spot: Funding rate is near zero. No one pays anyone.

The funding rate is typically between 0.01% and 0.1% per payment period. On a $10,000 position, that’s $1 to $10 every 8 hours. Over a week, it can add up — but for most traders, it’s a small price for the flexibility of no expiration.

I remember my first time trading perps. I opened a long on Ethereum at $1,800, planning to hold for a month. With quarterly futures, I would’ve had to roll over twice, paying spreads each time. With perps, I just set my stop loss and checked in weekly. The funding rate cost me about $40 total — way less than the slippage from rolling.

Why Should Traders Prefer Perpetual Contracts?

The biggest advantage is flexibility. You can enter a trade and hold it for as long as you want — no deadlines, no forced settlements. This is huge for swing traders who hold positions for weeks or months.

Another benefit is leverage. Perpetual contracts typically offer up to 100x leverage on major pairs like BTC/USDT. That means a $1,000 margin can control a $100,000 position. But be careful — high leverage cuts both ways. A 1% move against you can liquidate your entire position.

Perps also have lower barriers to entry. Most exchanges let you start with as little as $5 or $10. Compare that to traditional futures, where contract sizes can be huge — like one Bitcoin contract being 5 BTC. Perps use smaller contract sizes, making them accessible to retail traders.

Let’s look at a real-world example. In March 2020, Bitcoin crashed from $8,000 to $3,800 in a single day. Perpetual contract volume spiked to $30 billion in 24 hours, according to exchange data. Traders who were short made massive profits. But those who were long and overleveraged got wiped out. The key takeaway? Perps amplify everything — gains and losses.

Can You Hold a Perpetual Contract Forever?

Technically, yes — but only if you have enough margin to cover potential losses and funding fees. The contract itself never expires, but your position can get liquidated if the market moves against you.

Here’s what you need to manage:

• Maintenance margin: The minimum amount of collateral required to keep your position open. If your margin drops below this level, you get liquidated.
• Funding fees: You pay or receive these every 8 hours. Over a long holding period, they can eat into profits — or boost them if you’re on the receiving end.
• Mark price vs. last price: Most exchanges use the mark price for liquidation calculations, which smooths out volatility. But if the last price spikes, you can still get caught.

For long-term holders, a common strategy is to use lower leverage — like 2x to 5x — so you can weather drawdowns. I’ve seen traders hold perp positions for over a year. But they monitor their margin ratio weekly and add collateral when needed.

If you’re new to perps, start small. Use a demo account first. And never risk more than you can afford to lose. For a deeper dive, check out Lido DAO LDO Perpetual Futures Strategy for Sideways Markets.

One more thing: some exchanges have introduced “funding rate caps” to protect traders during extreme volatility. For example, Binance caps the funding rate at 0.75% per 8-hour period. So even in a crazy market, you won’t get hit with insane fees.

So Where Do You Go From Here?

You now understand the core mechanic that makes perpetual contracts tick — no expiration, just a funding rate that keeps everything fair. But here’s the real question: are you ready to put this knowledge into action? Start by opening a small position on a pair you know well, track the funding rate for a week, and see how it feels to hold a trade without a deadline. That hands-on experience will teach you more than any article ever could.
