What is funding-rate capture (delta-neutral funding yield)?
What is a perpetual funding rate?
A payment between perp longs and shorts that keeps the price tethered to spot. When the perp trades above spot — the usual state — longs pay shorts.
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: funding-rate capture.
The edge is structural — leveraged long demand pays for the short side — and it turns negative when the market flips net-short.
A thin edge, and not in 2026
The edge is small per period, so costs decide. Fygga’s backtest (five pairs, Binance, 1 Jan 2022 – 24 Jun 2026, totals over the window, both legs charged):
| Gross funding accrual (before costs) | +19.3% | 4.0% CAGR — the inefficiency exists in isolation |
| Net return, weekly rebalance (after costs) | +2.8% | Sharpe 0.50 · 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 |
