Get paid to hold a hedged position. Funding rate arbitrage turns perpetual futures mechanics into steady yield.
Updated 2026-10-05 · 10 min read
Funding rate arbitrage — the classic cash-and-carry trade — earns yield from the funding payments on perpetual futures contracts while staying market-neutral. When perpetuals trade above spot, longs pay shorts a funding fee every few hours. By holding long spot + short perps in equal size, price moves cancel out and you simply collect the funding.
In strong bull markets, annualized funding on majors like BTC and ETH has historically printed double digits. But funding flips sign, and the trade has real risks. Here is the full picture.
Perpetual futures never expire, so exchanges use funding payments to tether the perp price to spot. Every 1–8 hours (exchange-dependent), traders on the expensive side pay traders on the cheap side. Positive funding = longs pay shorts. Negative funding = shorts pay longs.
Funding is variable, not guaranteed
That eye-catching APR assumes funding stays elevated. Funding can collapse to zero or flip negative within hours when sentiment turns — your yield is a weather forecast, not a fixed deposit.
| Risk / cost | Detail |
|---|---|
| Funding flip | Negative funding means *you* pay. Have an exit rule. |
| Basis risk | Spot and perp can diverge briefly; your hedge is not mathematically perfect. |
| Liquidation | The short perp uses margin — a violent spike can liquidate it even though spot covers the loss economically. |
| Fees | Opening/closing two legs plus ongoing margin costs eat into yield. |
| Exchange risk | Your capital sits on a derivatives exchange — counterparty risk is real. |
The edge is in scanning funding rates across many exchanges and pairs simultaneously — the highest payers change daily. A dedicated crypto arbitrage scanner with funding-rate coverage surfaces the top payers ranked by net yield, so you are not manually refreshing a dozen futures dashboards.

No. It is market-neutral, which removes directional risk, but funding flips, liquidation risk, fees and exchange risk remain. Treat it as low-volatility yield, not a savings account.
You need enough to hold both legs plus margin buffer — typically a few thousand dollars minimum for the math to beat fees, though paper trading lets you learn the mechanics free.
High-liquidity perps with persistent funding skew — historically BTC, ETH and large-cap alts during trending markets. Illiquid perps have juicier headline rates and much worse execution.
