Understanding Perpetual Swaps: The Crypto Market's Most Popular Trading Instrument

Perpetual swaps, also known as perps, are a type of trading instrument that has revolutionized the crypto market. They allow traders to gain leveraged exposure to assets like bitcoin without actually owning them. Despite their widespread use, the mechanics behind perps are not well understood. To grasp how perps work, it's essential to understand the traditional finance context. In the past, traders used futures contracts to gain exposure to assets, but these contracts had expiration dates, which led to issues like basis and forced position closures. BitMEX addressed these problems by introducing perps, which have no expiration date and allow traders to hold positions indefinitely. The exchange achieved this through a funding rate mechanism, where traders on opposite sides of the market exchange payments every eight hours, keeping the perp price in line with the underlying asset's spot price. Leverage is another key feature of perps, enabling traders to control large positions with minimal capital. However, this also increases risk, which is managed through automated liquidation systems. Today, perps are the primary venue for price discovery in crypto, with regulators exploring their application to traditional assets. The structure of perps has proven resilient, and they have become one of the most widely traded financial products globally.
