Understanding Perpetual Swaps: The Dominant Force in Crypto Trading
Perpetual swaps, also known as perps, have revolutionized the crypto market by providing a trading instrument that processes an estimated $40 trillion to $50 trillion in volume annually. They have surpassed spot trading in popularity and are the go-to product for professional traders, hedge funds, and retail speculators seeking leveraged exposure to asset prices. Despite their widespread use, the mechanics behind perps are not well understood. To grasp the concept of perps, it's essential to understand the traditional finance context. In the past, leveraged exposure to assets was typically achieved through futures contracts, which involved an agreement to buy or sell an asset at a set price on a specific date. However, this approach created persistent problems in the crypto market, including basis and contract expirations that confused retail traders. The launch of perpetual swaps on BitMEX in 2016 addressed these issues by eliminating the expiry date, creating a derivative contract that tracks asset prices indefinitely. This innovative approach introduced a structural challenge, which was resolved through a funding rate mechanism that has become the industry standard. Every eight hours, a payment is exchanged between traders on opposite sides of the market, with the rate calculated based on the deviation from the spot price. This self-correcting equilibrium ensures that the contract price remains aligned with the underlying asset price. Perpetual swaps also offer leverage, allowing traders to control positions significantly larger than their deposited capital. To manage the associated risks, exchanges use automated liquidation systems to close positions before they can go negative. The significance of perpetual swaps extends beyond the crypto market, with regulators exploring their application to traditional assets. As the primary venue for price discovery in crypto, perps have proven to be a durable and influential financial product, with their impact expected to be felt across the broader financial landscape.
