Perpetual Swaps

How it works

A perpetual swap tracks the price of an underlying asset with no fixed expiry date, using a continuous funding rate to keep the contract price anchored to spot. A holder of a long perpetual on an asset profits when the price rises and loses when it falls, the same delta-one exposure as holding the underlying directly. At regular intervals, typically every eight hours, longs pay shorts when the contract trades above spot and shorts pay longs when it trades below, a continuous payment pressure that keeps the price anchored without ever forcing settlement.

Perpetuals beat dated futures on two counts. There is no fragmentation, since dated futures split liquidity across many expiries while a perpetual concentrates all liquidity into a single contract per underlying asset, producing deeper liquidity and better execution for every participant. And there is no rolling, since dated futures require a trader to close and reopen a position near expiry or lose liquidity as settlement approaches, while a perpetual position simply never needs to be rolled.

Perpetuals also beat options for anyone seeking simple leveraged exposure rather than a view on volatility. Options require understanding volatility, time decay, and the choice of strike and expiry; a trader who wants five times long exposure to an asset can get it from a perpetual without any of that knowledge, just by buying with leverage. Options also fragment liquidity across a grid of strikes and expiries, producing wider spreads than the single corresponding perpetual contract would carry. Jeff Yan's framing: perpetuals are "the best way currently known and proven at scale for creating a liquid market for price discovery and speculation on a single number that evolves continuously over time," and most of traditional finance reduces to exactly that kind of bet.¹

Origin and expansion

A crypto derivatives exchange pioneered the perpetual swap at scale around 2014; Yan recalls first noticing the instrument by seeing anomalous trading volume there, with a funding-rate basis that was wildly mispriced when he first looked and had closed a year later as sophisticated arbitrage arrived, evidence the market had genuinely been inefficient before. He credits the instrument's originators with a real zero-to-one innovation that the rest of crypto owes a debt to.

Since then, perpetuals on gold already trade on decentralized exchanges, and Yan expects broader commodity and equity perpetuals within roughly a year via a permissionless deployment framework that lets any team specify market parameters and launch without infrastructure work of their own.² He also expects the first centralized exchange to shut down its own perpetual product within a year and simply run a front end on the same permissionless infrastructure instead, which would be the most concrete validation available that a competitor is conceding the underlying infrastructure layer entirely and competing only on distribution.

Implications for traditional finance

Much of retail equity options trading functions as delta-one leverage-seeking in disguise rather than genuine volatility trading, which implies perpetuals on equities or equity indices would be a structurally superior product for that same demand if regulators allowed them. Yan is bullish on that regulatory trajectory, describing institutions as increasingly viewing the instrument as a technical innovation applicable broadly across markets rather than a crypto-specific curiosity.

The exchange-competition angle

CZ (Changpeng Zhao) supplies the market-structure view from the incumbent exchange side. A major crypto exchange did not invent perpetual swaps; it launched them roughly five years after the originator did and built dominance purely from user base, which produced liquidity depth, which produced the best prices and lowest slippage, a notable admission that execution advantages compound from scale rather than from having invented the instrument first. Traditional derivatives exchanges entering the US perpetuals market are, in his account, unambiguously good: "the more people trading crypto perps, the better liquidity is, and better liquidity is actually the best protection for consumers." He frames market-share competition as secondary to total liquidity expansion: "which will get bigger is actually less important to me than total crypto perp trading expanding."³

Open questions

The instrument's comprehensibility without understanding funding is also a risk, since users can hold a position through a funding-rate regime that steadily loses money without understanding why; the abstraction hides complexity rather than eliminating it. And the fragmentation advantage over dated futures assumes a single liquid perpetual market per asset, which is not guaranteed if permissionless deployment allows multiple competing perpetual markets on the same underlying asset to launch at once.
