Uncovering Perpetual Swaps: The Driving Force Behind Crypto's Most Popular Trading Instrument
Perpetual swaps, or 'perps', have become the go-to instrument for professional traders, hedge funds, and retail investors seeking leveraged exposure to cryptocurrency prices without directly owning the assets. Despite their widespread adoption, the underlying mechanics of perps remain poorly understood. To grasp the concept of perps, it's essential to consider their origins. In traditional finance, futures contracts provide leveraged exposure to assets, but these contracts expire on a specific date, requiring traders to roll over their positions. The early days of crypto saw persistent issues with this approach, including futures trading at a premium to spot prices and positions automatically closing upon contract expiration. BitMEX, a derivatives exchange, addressed these problems by introducing perpetual swaps in 2016. This innovative contract type eliminated expiry dates, allowing traders to hold positions indefinitely. A key challenge arose: without an expiry date, the contract price could drift away from the underlying asset's spot price. To counter this, a funding rate mechanism was implemented, where traders on opposite sides of the market exchange payments every eight hours. This self-correcting system has become an industry standard. Perpetual swaps also offer high leverage, enabling traders to control large positions with relatively small amounts of capital. However, this increased risk necessitates the use of automated liquidation systems to protect exchanges from potential losses. Today, perpetual swaps are the primary venue for crypto price discovery, with regulators exploring their application to traditional assets. The structure of perps has proven resilient, and their influence extends beyond the crypto market, with the potential to shape the future of financial trading.
