Crypto Perpetual Swaps Grow Into $50 Trillion Market

Perpetual futures are among crypto’s most heavily traded derivatives, allowing investors to take leveraged positions without an expiry date or direct ownership of the underlying token. Centralized exchanges, or CEXs, still dominate the business, while decentralized exchanges, or DEXs, provide an onchain alternative. A simultaneous decline across both venues matters because it points to weaker speculative demand, thinner liquidity and reduced risk appetite across the digital-asset market.

CEX perpetual futures volume fell to $4 trillion in July, the lowest level in 31 months and the weakest since late 2023. DEX perpetual volume also dropped to $531 billion during the month. Daily cryptocurrency spot trading volume declined alongside derivatives activity, indicating that the slowdown was not confined to leveraged products. The figures show a broad contraction in market participation and trading demand across both centralized and decentralized crypto venues.

Perpetual futures have become crypto’s dominant derivative by offering leveraged exposure without an expiry date, concentrating liquidity in a single contract and improving margin efficiency. Funding payments between long and short traders keep contract prices near spot markets. Perps now account for about 70% of Bitcoin trading volume, but their shared collateral, continuous trading and embedded leverage can transmit stress rapidly across venues when crowded positions unwind.

Traders warn that funding is a recurring carrying cost rather than a one-time exchange fee: positive rates require longs to pay shorts, while negative rates reverse that flow. The risk surfaced on Oct. 10, 2025, when about $19 billion of crypto positions were liquidated in one day. Binance’s BTC/USDT perpetual traded nearly 5% below the spot index during the selloff, while CoinGlass data showed funding rates falling to a three-year low.
