The crypto basis trade involves simultaneously buying spot and selling futures/perpetuals on the same asset to earn the funding rate or futures premium (basis) while maintaining zero directional exposure. It is sometimes called cash-and-carry arbitrage and is a widely used institutional yield strategy.
The basis in crypto refers to the price difference between a spot asset and its derivative (futures or perpetual). When futures/perps trade at a premium to spot (normal in bull markets), this premium represents yield that can be captured via the basis trade.
**Two variants:**
**1. Perpetual basis trade (funding rate harvest):** - Buy 1 BTC spot - Short 1 BTC perpetual - Net BTC exposure: 0 - Earn positive funding payments when longs pay shorts - Typical yield: 10–40%+ APY during bull markets
**2. Futures basis trade (cash-and-carry):** - Buy 1 BTC spot - Sell 1 BTC at a fixed-date futures contract trading at premium - At futures expiry, deliver spot BTC, receive the futures premium - Yield: Annualized futures premium (basis)
**Basis terminology:** - **Contango**: Futures trade above spot — positive basis — normal in crypto bull markets - **Backwardation**: Futures trade below spot — negative basis — common in bear markets/high uncertainty
**Institutional adoption:** High-profile institutional products (Ethena's USDe, various "delta-neutral" yield funds) have aggregated this trade at scale. Ethena holds billions in basis trade positions to generate yield backing a synthetic dollar.
**Risks:** - **Funding flip**: Positive funding turns negative (paying instead of earning) - **Liquidation risk**: Leveraged exchange positions can be liquidated during high volatility - **Exchange insolvency**: FTX collapse destroyed basis trade positions - **Correlation breakdown**: Spot and perp prices diverging more than expected during stress
Frequently Asked Questions
How much yield does the crypto basis trade historically generate?
During bull markets, funding rates can average 0.05–0.10% per 8 hours (18–36% annualized), making the basis trade highly lucrative. During bear markets, funding often turns neutral or negative. Across full cycles, sustainable annualized yields have ranged from 5–20%, with peak bull market periods yielding 30–50%+. Historical funding rate data is available on Coinglass.
What is Ethena's USDe and how does it use the basis trade?
Ethena's USDe is a synthetic dollar backed by the basis trade at scale. Users deposit ETH/BTC/stablecoins → Ethena holds spot and shorts perps → funding income goes to stakers (sUSDe). When funding rates are positive, sUSDe holders earn high yields. When funding goes negative, Ethena draws from an insurance fund. The design works well in bull markets but has clear vulnerability when funding turns persistently negative.
What is the difference between futures basis and perpetual funding basis?
Futures basis is the premium of a fixed-expiry futures contract over spot. At expiry, the basis converges to zero — the trade is time-limited but has a guaranteed payoff. Perpetual funding basis is ongoing — the trade earns funding as long as you hold it, but the rate can change. Futures basis trades have more predictable outcomes; perpetual funding trades have more duration flexibility but variable yield.

Funding Rate (Perpetual Futures)
The funding rate is a periodic payment mechanism in perpetual futures that keeps the contract price close to the spot price. When the perpetual trades above spot (bullish market), longs pay shorts. When it trades below spot (bearish market), shorts pay longs. Rates reset every 1 or 8 hours depending on the exchange.
Delta-Neutral Strategy
A delta-neutral strategy creates a position with zero net exposure to price direction by combining long and short positions of equal delta. This allows yield generation from funding rates, option premium, or liquidity provision without taking directional risk on the underlying asset's price.
Open Interest (Crypto Derivatives)
Open interest (OI) is the total number of outstanding derivative contracts (perpetuals, futures, options) that have not been settled or closed. Rising OI during a price move confirms trend strength; falling OI suggests the move is driven by position exits rather than new capital entering.
Perpetual DEX
A perpetual DEX is a decentralized exchange that offers perpetual futures contracts on-chain, allowing traders to go long or short crypto assets with leverage without a centralized intermediary. Leading examples include GMX, dYdX, and Hyperliquid.
