Understanding Perpetual Swaps: The Most Traded Financial Product in Crypto

Perpetual swaps, also known as perps, have revolutionized the crypto market by providing a unique trading instrument that offers leveraged exposure to asset prices without owning the underlying asset. To grasp the concept of perps, it's essential to understand the traditional finance context. In the past, traders relied on futures contracts, which had expiration dates and required rolling over to maintain positions. However, this approach created issues in the crypto market, such as basis and contract expirations. BitMEX addressed these problems by introducing the perpetual swap in 2016, a contract that has no expiration date and tracks the asset price indefinitely. The exchange solved the structural challenge by implementing a funding rate mechanism, where traders on opposite sides of the market exchange payments every eight hours. This self-correcting equilibrium ensures that the contract price remains aligned with the spot price. Perpetual swaps also offer high leverage, allowing traders to control large positions with minimal capital. To mitigate the risks, exchanges use automated liquidation systems to close positions before they become negative. Today, perpetual swaps are the primary venue for price discovery in crypto, with regulators exploring their application to traditional assets. The innovation that began as a workaround for crypto futures has become a cornerstone of global finance, with a significant impact on the trading landscape.
