Crypto-Margined vs. Stablecoin-Margined Perpetual Futures
Summary
The document compares crypto-margined perpetual futures with USDT- or USDC-margined contracts. It explains differences in quote currency, contract face value, collateral, and profit-and-loss settlement. In its examples, a BTC/USD crypto-margined contract uses BTC as collateral and settles PnL in BTC, while a BTC/USDT contract uses a stablecoin for margin and PnL. Contract specifications vary by product, so traders need to check the exchange’s rules rather than assume the examples apply universally.
The central risk distinction is that crypto collateral changes in dollar value alongside the position. This creates exposure beyond the contract’s price movement and can make portfolio outcomes nonlinear in USD terms. Stablecoin-margined contracts make PnL more directly dollar-linked, though they still carry futures risks such as leverage and liquidation. The document suggests matching the margin type to market conditions, but gives no tested strategy or quantitative evidence for its directional recommendations.
Key ideas
- U-margined contracts use USDT or USDC for collateral and PnL accounting, while crypto-margined contracts use the underlying crypto asset.
- Quote currency and contract face value determine how a contract is denominated and its index price is formed.
- Crypto collateral adds exposure to changes in the collateral asset’s value relative to dollars.
- The document’s market-direction suggestions are not supported by backtests or measured results.
