What to Know

  • Perpetual futures, often called perps, are derivatives contracts that resemble standard futures but do not expire.
  • Crypto perps average daily volume of over $200 billion, reflecting their central role in digital asset trading.
  • Outside bitcoin and ether, dated futures liquidity is often thin, making perps the main derivatives venue for many altcoins.
  • Traders value perps for deep liquidity, low trading fees and strong margin efficiency.
  • Funding rates are a recurring cost for keeping perp positions open and are typically charged every eight hours.
  • Funding rates can change over time, making long-held positions harder to price than dated futures.
  • Some traders argue the main risk is not the perpetual structure itself but crypto exchange margin systems and socialized loss mechanisms.
  • Market participants expect perpetual-style products to expand further into tokenized commodities, equities and other asset classes.

Perpetual Futures Move to the Center of Crypto Trading

Perpetual futures have become one of the defining instruments of crypto markets. Known across trading desks as perps, these contracts allow traders to control a larger position than the money sitting in the account would otherwise permit. They operate similarly to standard futures, with one crucial distinction: there is no expiry date forcing the position to roll into a new contract.

That feature has made perps especially important in digital assets, where markets trade around the clock and liquidity can shift quickly from one venue to another. Bitcoin and ether traders can choose among spot markets, futures, options, perpetual futures and structured products. For many other tokens, however, the menu is far narrower. Dated futures are often too thinly traded to be practical, while spot markets may be less attractive for anyone who is not planning to hold the underlying asset for the long term.

As a result, perps are no longer just another instrument in the crypto toolkit. For many market participants, they are the default mechanism for gaining exposure, hedging inventory, expressing directional views and moving risk across venues. The appeal is straightforward: liquidity is generally deeper, trading fees can be competitive and collateral can be used more efficiently than in many alternatives.

Why Traders Rely on Perps

The case for perps starts with market structure. Crypto perps average daily volume of over $200 billion, a scale that reflects both trader preference and market necessity. Liquidity matters because it determines whether large buy or sell orders can be absorbed without sharply moving the market. When liquidity is thin, slippage rises, execution deteriorates and the cost of entering or exiting a position can become unpredictable.

Lucas Krenn, a derivatives trader at market-making firm STS Digital and an independent trader for six years, framed perps as essential infrastructure for crypto-native firms. Outside bitcoin and ether, he said, dated futures liquidity is thin to the point of being unusable. In that environment, perps are not one tool among several; they are the tool.

Dated futures also introduce operational friction because they expire. Traders need to replace expiring contracts with new ones, a process that can create costs and inefficiencies. That same dynamic is one reason futures-based exchange-traded products can be less efficient than spot products in markets where both structures exist. Perps avoid that specific roll problem by design, allowing positions to remain open so long as margin requirements are met and the trader chooses to hold.

Retail traders describe a similar draw. Kenneth Ong, an independent trader for six years whose activity is concentrated mainly in perps, has pointed to better fills, lower fees and the flexibility of hedge mode. Hedge mode allows a trader to hold long and short positions on the same token at the same time in the same account, with the positions treated separately rather than automatically netted. That can be useful for managing event risk, short-term volatility or strategy overlays.

For Ong, spot markets are now mainly for actually holding an asset over the long term. For active trading, perps offer the execution environment and flexibility he wants. This divide captures a broader market pattern: spot is often associated with ownership, while perps are increasingly associated with active risk-taking, hedging and tactical positioning.

Margin Efficiency Is the Core Attraction

Beyond liquidity and fees, margin efficiency is one of the strongest reasons traders gravitate toward perps. Margin efficiency refers to how much market exposure a trader can control for each unit of collateral posted. Since perps require only a fraction of the position’s value as collateral, the same capital base can support meaningful positions across multiple tokens and venues.

This is particularly important in crypto because liquidity is fragmented. A trader may need to operate across a dozen venues to access the best pricing, manage counterparty risk or trade specific token contracts. The leverage embedded in perp markets allows capital to be distributed across those venues while still backing positions large enough to matter.

That efficiency cuts both ways. It can help sophisticated traders manage risk with less idle capital, but it also increases the danger of forced liquidations when markets move quickly. Because positions are leveraged, even a relatively small adverse price move can create a margin shortfall. If the account cannot support the position, the exchange may close it automatically.

Still, experienced traders often argue that liquidations are not the only, or even the most misunderstood, issue in perps. The funding rate is the recurring cost that can quietly reshape the economics of a trade.

Funding Rates Are the Cost Traders Cannot Ignore

Perpetual futures need a mechanism to keep contract prices aligned with spot prices because they do not expire. That mechanism is the funding rate. In practical terms, funding is a recurring payment exchanged between long and short traders. It is typically charged every eight hours and changes over time depending on market conditions.

A dated futures contract gives traders more clarity about the embedded interest rate of the trade at entry. A perp does not. The funding rate floats, meaning the trader remains exposed to a changing cost or income stream for as long as the position is held. If the market moves as expected, funding may be manageable. If the market stalls or moves slowly, funding can become a major drag.

Krenn described the problem as difficult to quantify at the point of trade and difficult to hedge after the position is open. Ong was more direct, warning that funding is not a tiny fee traders can safely ignore. For positions held over long periods, he said, funding can potentially grow to the point where a profitable trade loses money.

This is why funding has become a central concern for both retail and institutional traders. Trading fees are visible and easy to compare across platforms. Funding is dynamic, path-dependent and shaped by crowd positioning. A trader entering a perp may know the funding rate at that moment, but not what it will be across the full life of the trade.

Perps Push Price Discovery Beyond Traditional Market Hours

Because crypto markets never close, perps can become the venue where price discovery happens when traditional markets are shut. This has become especially relevant as perpetual-style products spread beyond native crypto assets into tokenized commodities and other markets.

Ong has pointed to the Iran conflict, which flared up repeatedly across the first half of 2026, as an example of how weekend trading can shift the timing of repricing. During the conflict’s opening weekend in late February, tokenized oil trading on Hyperliquid saw its first real surge in volume. While official markets were closed, crypto and tokenized commodity perps absorbed the immediate reaction. By Monday, some repricing had already taken place elsewhere.

This illustrates why traders expect perpetual markets to expand further. A tokenized equity product that recreates traditional share ownership on-chain can be legally, operationally and regulatorily complex. A perpetual contract that references a price can sidestep much of that infrastructure for traders who want exposure rather than long-term ownership. That distinction helps explain why the perp model is moving into new asset classes.

Ong has described weekend tokenized oil trading as a preview of what could come for other commodities. If liquidity deepens across commodities and equities, some traders believe perps could reduce the practical need for dated futures in certain speculative or hedging use cases.

The Oct. 10 Crash and the Myth of the Safe Trade

Perps faced heavy criticism after bitcoin’s current bear market began with the Oct. 10 crash last year, which triggered widespread deleveraging across both losing and profitable positions. Long positions were liquidated as prices fell, which is a familiar feature of leveraged trading. More controversially, some profitable short positions were force-closed because exchange insurance funds could not absorb losses from the other side.

That episode challenged the assumption that being right and well-capitalized is always enough. If an exchange’s risk engine socializes losses onto profitable traders, a correct position can still be affected by platform-level stress. Krenn argues that this is not fundamentally a perpetual futures problem. In his view, the issue is the crypto exchange margin model.

Dated futures on the same venues can sit behind the same insurance funds and deleveraging queues. The more important distinction, he argues, is whether traders face a proper clearing house with a mutualized default fund or an exchange model that can pass losses onto winners when stress overwhelms the system.

That point matters as perpetual markets grow. The contract design may be efficient, but the venue’s margin rules, insurance structure and liquidation engine are just as important as the position itself.

The Asymmetry in Funding Risk

Krenn also highlights an asymmetry that many risk models may not fully capture. In his view, being long can be structurally safer than being short in certain perp markets. The reasoning comes from how funding can be arbitraged.

When funding is positive, traders holding stablecoins can buy spot, sell the perp and collect the spread, which can compress positive funding. When funding is negative, the reverse cash-and-carry trade is harder. It requires going long the perp and short the spot asset, but shorting the underlying token may only be easy for existing holders. If supply is small and concentrated, the trade can be difficult to execute.

That means negative funding can persist for extended periods when arbitrage is constrained. Krenn pointed to the lending protocol Euler’s token this year as an example, describing a hard run on a listing with a small and concentrated float. In that case, perp funding went deeply negative, with shorts paying in the region of one percent every four hours to longs, while few participants had enough token inventory to compress the gap.

The implication is stark. The long side may have a bounded cost and unbounded upside, while the short side may have bounded upside and unbounded cost. For traders who treat funding as a secondary detail, that asymmetry can become a serious blind spot.

Perps Are Powerful, but Not Free

Perpetual futures have helped democratize crypto derivatives by improving access, reducing some trading costs and allowing capital to be used more efficiently. They have also become essential for altcoin markets where dated futures are too illiquid and spot trading is not always suited to active strategies.

Yet the instrument’s benefits come with distinct risks. Liquidations remain a visible danger, but funding is the quieter cost that can accumulate in the background. It cannot always be known in advance, it can shift sharply with positioning and it can turn an otherwise sound trade into a losing one if the position is held too long.

Until crypto develops a liquid dated futures curve across more assets, traders will continue to rely on perps while carrying an interest-rate exposure they cannot fully price or hedge. In that sense, funding is the tax paid for easy access to leveraged, always-on crypto markets.

Frequently Asked Questions (FAQs)

What are perpetual futures in crypto?

Perpetual futures are derivatives contracts that allow traders to take leveraged long or short positions without an expiry date. They resemble standard futures but do not require traders to roll into a new contract at expiration.

Traders use perps because they often provide deep liquidity, lower trading costs and strong margin efficiency. For many altcoins, perps may be the only practical derivatives market available.

How large is the crypto perp market?

Crypto perpetual futures average daily volume of over $200 billion, showing how central they have become to digital asset trading and risk management.

What is a funding rate?

A funding rate is a recurring payment tied to holding a perpetual futures position. It is typically charged every eight hours and can be paid by longs to shorts or by shorts to longs, depending on market conditions.

Why do traders worry about funding rates?

Funding rates change over time, so traders cannot know the full cost of holding a perp position when they enter the trade. If funding moves against the position and the trade is held for a long period, the cost can become significant.

Are liquidations the biggest risk in perps?

Liquidations are a major risk because leverage can force positions to close when margin runs short. However, some experienced traders argue that funding-rate exposure and exchange margin models are equally important risks.

How do perps affect price discovery?

Because perps trade continuously, they can absorb news and market reactions when traditional venues are closed. Tokenized commodity perps, for example, can reflect weekend developments before official markets reopen.

Are perps only used for bitcoin and ether?

No. Bitcoin and ether have broader derivatives markets, but many altcoins rely heavily on perps because dated futures liquidity is often thin and spot markets may not suit active traders.

Can perps expand into other asset classes?

Market participants expect perpetual-style products to continue spreading into tokenized commodities, equities and other assets. The appeal is that traders can gain price exposure without needing the full infrastructure of traditional ownership.
