What is a crypto carry trade?
A crypto carry trade is a market-neutral strategy that captures the spread between two related instruments — typically spot and futures — while hedging directional risk. The trade earns either the perpetual funding rate (spot-perp variant) or the annualized basis (cash-and-carry variant with dated futures). Both variants aim for low-correlation yield: you profit from the structural spread regardless of whether BTC goes up or down. The carry trade is the foundational yield strategy of crypto derivatives — used by dedicated funds, market makers, and retail traders seeking uncorrelated crypto returns. Historical BTC and ETH carry trades have yielded 10–40% annualized during bull markets, with yields compressing to 3–8% during bear phases.
Variant 1: Spot-perp carry (funding rate arbitrage)
The simplest variant: buy spot BTC + short equivalent notional BTC perpetual on the same exchange. When funding is positive (the common case in bull markets), the perpetual shorts receive funding payments from the longs. Your net exposure is zero (the spot gain offsets the perp loss on price moves, and vice versa), and you collect the funding rate as yield. Settlements happen every 8 hours on Binance/Bybit/OKX or every 1 hour on Hyperliquid. Annualize using APR = rate × (8,760 / interval_hours). A 0.01% 8-hour rate equals 10.95% APR; a 0.005% 1-hour rate on Hyperliquid equals 43.8% APR. For detailed mechanics and risk analysis see /arbitrage/guide/funding-rate-arbitrage.
Variant 2: Cash-and-carry basis trade
The dated-futures variant: buy spot BTC + short BTC quarterly or monthly futures. At expiry, the futures price converges to spot and you capture the annualized basis. Unlike funding rate arbitrage which earns continuous payments, the basis trade has a fixed payoff at a known date. In bull markets with strong contango (futures above spot), BTC CME and Deribit quarterly basis has historically yielded 10–15% annualized. The cleanest expression uses CME BTC futures (regulated, institutional) with CME-approved spot exposure through a regulated custodian. Less institutional traders use Deribit or OKX dated futures paired with spot on the same exchange.
Worked example: $100K spot-perp carry on Binance
Scenario: $100,000 deployed across spot long BTC + perp short BTC on Binance. Current 8-hour funding rate: 0.02% (~22% annualized). Maker fee tier: 0.02%. Target holding period: 30 days. Gross funding per 8h settlement: $100,000 × 0.0002 = $20. Settlements in 30 days: 90 (3/day). Gross funding over hold: $1,800. Round-trip fees (4 legs, 0.02% each): $80. Net PnL: $1,720. Annualized net APR: ($1,720 / $100K) × (365/30) × 100 = 20.9%. Use Sharpe's arbitrage calculator at /arbitrage/calculator to model different rate assumptions and holding periods.
Execution walkthrough
Step 1: Identify the opportunity — Sharpe's funding rate leaderboard ranks by APR with OI context. Pick pairs with $10M+ OI for meaningful sizing. Step 2: Verify the basis — check that spot-perp basis is tight (< 10 bps) so entry is clean. Step 3: Place both legs simultaneously as maker limit orders to minimize fees. Enter 30–60 minutes before the next funding settlement to capture near-full first payment. Step 4: Monitor funding drift — if the rate halves, exit and redeploy. Step 5: Monitor short-leg liquidation buffer — use isolated margin with 3–5× the maintenance requirement. Step 6: Close both legs together when yield is captured or the opportunity decays.
Risk management
Three risks dominate. First, funding normalization — extreme APRs mean-revert within hours. Model your realistic holding period before committing capital. Second, short-leg liquidation — the perpetual can wick sharply higher even during a flat spot session. Isolated margin with 3–5× the maintenance buffer is the standard; a 30–50% price spike shouldn't liquidate you. Third, exchange counterparty risk — diversify across 2–3 exchanges rather than concentrating $500K+ at any single venue. Beyond these, operational risk (wallet errors, stablecoin network mismatches) is the largest source of retail carry-trade losses.
When carry trades fail
Classic failure mode: entering at peak funding, which mean-reverts toward zero within hours as the same arbitrage you're running compresses the dislocation. The calculator's break-even column shows how low funding can go before your trade becomes unprofitable. Other failures: liquidation on the short leg during a squeeze (even with isolated margin, a 40–50% price spike can blow through buffers on small positions), stablecoin network failures during transfers (USDT-ERC20 has had multi-hour delays), and exchange-wide halts during extreme volatility. Size for these scenarios.
