#What Are Perpetual Futures and How Do They Work?
Perpetual futures are contracts in the cryptocurrency market that do not have an expiration date. They closely resemble total return swaps, in which one party receives all the gains and losses of an asset while the other party receives a financing payment. These contracts maintain their prices closely aligned with the spot market through periodic funding rate payments. When market demand rises sharply for long positions, the funding payments can become quite costly.
The funding rates are set every eight hours on various trading platforms like Binance and OKX, where longs pay shorts or vice versa based on the prevailing market conditions. If the funding rates exceed 0.3% per eight-hour interval, traders can incur approximately 0.9% in daily costs just to maintain a long position. Thus, those traders are betting that the asset price will increase sufficiently to offset these carrying costs.
#How Are Institutional Players Engaging with Perpetual Futures?
In March 2026, Amundi announced the launch of a substantial tokenized fund, valued at $100 million, which operates on Ethereum and Stellar networks. This fund employs collateralized total return swaps, marking a pivotal moment where one of Europe’s largest asset managers is delving into institutional-grade products that leverage the same mechanisms found in perpetual futures trading.
#What Is Ethena and How Does It Profit from Funding Rate Arbitrage?
Ethena has developed a unique business model focused on funding rate arbitrage. Recent reports indicate that Ethena possesses around $7.83 billion in undeployed capital for capturing premium during funding rate spikes. This figure amounts to nearly 12% of the total open interest in perpetual futures. Ethena's strategy capitalizes on situations where a large number of traders hold long positions, driving funding rates to high levels. Ethena takes the short side of these trades while utilizing spot market hedges to secure profits from the funding payments received.
#What Do Funding Rate Spikes Indicate in Crypto Markets?
Funding rate spikes have historically been reliable indicators of market sentiment in the crypto space. When the cost to hold leveraged long positions reaches unsustainable levels, even slight price declines can trigger liquidation cascades as traders scramble to exit unaffordable positions. This dynamic adds a layer of volatility to the crypto markets and highlights the importance of understanding funding rates for risk management and strategic trading decisions.
