What is funding-rate capture (delta-neutral funding yield)?
What a perpetual funding rate is, how a delta-neutral hedge collects it without price direction, and the honest answer to “is it actually profitable?”
What is a perpetual funding rate?
A perpetual future (“perp”) has no expiry. To keep its price tethered to spot, exchanges use a periodic payment between longs and shorts — the funding rate — exchanged every few hours. When the perp trades above spot (the usual state, because leveraged traders lean long), longs pay shorts; below spot, shorts pay longs. It is not a fee the exchange keeps.
How a delta-neutral hedge collects funding without price exposure
Shorting a perp alone leaves you exposed to price. The fix is a delta-neutral hedge: short the perpetual and hold an equal amount of the asset in spot. Price moves cancel (delta ≈ zero) and what is left is the funding payment. That is funding-rate capture, also called delta-neutral funding yield or basis capture.
The edge is structural: persistent, leverage-hungry long demand means someone has to be paid to take the short side. Its size varies with sentiment, and it can turn negative when the market flips net-short.
The honest answer: a modest edge, not a moonshot
The funding edge is real but small per period, so costs decide whether anything survives. Fygga’s committed backtest (five liquid pairs on real Binance history, 2022–2026, both trading legs charged in full):
| Gross funding accrual (before costs) | +19.3% | ~4%/yr — the inefficiency exists in isolation |
| Net return, weekly rebalance (after costs) | +2.8% | Sharpe 0.5 · max drawdown -5.3% |
| Annual cost drag | ~2.1%/yr | two-leg fees + slippage |
| Net return, daily rebalance (after costs) | -19.1% | rebalance too often and costs turn the edge negative |
Read plainly
Gross funding was about 4% a year — a genuine market-neutral edge. After realistic costs the honest net was +2.8% total at a weekly cadence with a -5.3% drawdown, and the daily-rebalance row shows how easily costs erase it. And funding can turn negative: when the market flips net-short, the hedged position pays instead of earns. Historical backtest figures, not a promise of future returns.
Why most bots hide this
“~4% a year” sells worse than “passive crypto yield.” Fygga shows the edge and the costs that eat it — including the strategies we tested and rejected — so you can judge it yourself. See what a funding rate implies over different periods on the estimator, or watch the live funding monitor.
Frequently asked questions
- What is funding-rate capture?
- Funding-rate capture is a market-neutral strategy that collects the periodic funding payment on crypto perpetual futures. You short a perpetual and hedge it with an equal long spot position, so price moves cancel out and you are left collecting (or paying) the funding rate. When the market is net-long — which it usually is — longs pay shorts, so a hedged short earns the funding with near-zero directional exposure.
- Is funding-rate capture profitable?
- The funding edge is real but modest, and costs decide whether anything survives. In Fygga's committed backtest (2022–2026, five liquid pairs), gross funding accrual was +19.3% (about 4% a year) before costs — but at a realistic weekly rebalance, net return was +2.8% total with a Sharpe of 0.5 and a -5.3% max drawdown after two-leg trading costs. Rebalanced daily, costs actually turned the same edge negative (-19.1%). It is a low-drama, market-neutral edge, not a moonshot. Backtest only — past performance is not indicative of future results.
- What are the risks of funding-rate capture?
- Funding can turn negative when the market flips net-short, so the position can pay instead of earn. Trading costs on both legs can erase the edge if you rebalance too often. There is also execution and basis risk between the perp and spot legs, exchange and counterparty risk, and the risk that the hedge is imperfect. It removes price direction as a risk, not all risk. This is educational information, not financial advice.
