The Misguided Debate Over Perpetual Futures and Systemic Risk

The introduction of perpetual futures into regulated markets has sparked concerns about systemic risk, with critics arguing that these high-leverage instruments pose a threat to the stability of the financial system. However, this critique is misplaced, as the risk is not inherent to the contract itself, but rather a result of the venue's design. The real issue lies in the choices made by the venue, such as leverage limits, margin rules, index construction, and default handling. These factors can either mitigate or exacerbate the risk of a systemic event. The recent episodes of deleveraging in the crypto market, including the October 2025 cascade, were caused by a combination of factors, including macro shocks, stablecoin de-pegs, exchange outages, oracle failures, over-leverage, and thin liquidity. The liquidation cascade that ensued was a result of the risk transmission mechanism, which is often the result of venue choices. The use of manipulable indices and auto-deleveraging can turn a sell-off into a systemic event. The key to preventing such events is not to ban perpetual futures, but to ensure that venues are designed with robust risk management systems. This includes segregated funds, registered clearing entities, and regulatory oversight. The way a venue handles defaults under stress is also crucial, and this can vary even within regulated markets. Another criticism of perpetual futures is that they may not be suitable for institutional investors, who may prefer traditional futures contracts. However, this criticism misses the point that perpetual futures are not intended to replace traditional futures, but rather to provide a complementary instrument for hedging and risk management. Many institutions use perpetual futures to hedge their delta exposure, and the liquidity provided by these contracts is a key factor in their appeal. In fact, the liquidity edge provided by perpetual futures is structural, and is drawn in part by retail investors. The design of perpetual futures, with no expiry date and continuous tradability, concentrates liquidity in these contracts. This liquidity is a prize that can be safely accessed by institutions with the right risk management systems in place. The debate over perpetual futures is often framed as a choice between risk and safety, but this is a false dichotomy. The real question is how venues can be designed to handle defaults and other stress events in a way that contains risk, rather than transmitting it to the broader market. The answer lies in the use of institutional-grade default management, such as regulated clearing and pre-funded guaranty funds. These systems can break the chain of risk that turns a single default into a market-wide cascade, and provide a safe and stable environment for institutions to access the liquidity provided by perpetual futures. In conclusion, the debate over perpetual futures and systemic risk is misguided, and the focus should be on the design of venues and the risk management systems they employ. With the right design and systems in place, perpetual futures can be a valuable tool for institutions and retail investors alike, providing a deep and durable pool of liquidity that can help to mitigate risk and promote stability in the financial system.
