Liquidation Distance vs Expected Funding Capture: The Asymmetry.

The asymmetry is this: a funding trade’s expected capture is measured in basis points per settlement window, while its liquidation risk is measured in your entire margin, and leverage moves the two in opposite directions. The same 10x that multiplies a 3 basis point capture into 30 basis points on margin also pulls your liquidation threshold to within a few percent of entry, on assets that move that much routinely. The trade earns like a bond and loses like a lottery ticket held the wrong way, and any analysis that quotes the yield without the distance is quoting half a number.

Put the two numbers side by side, because the ratio is the point. Suppose an expected gross capture of 28 basis points over an eight-hour window, generous by the standards of real spreads, against a liquidation distance of 5 percent at 10x on a thin perp. The loss-to-gain ratio is roughly eighteen to one: one liquidation erases eighteen perfect windows, six days of flawless harvesting, before fees. And the move that triggers it is not rare: 5 to 8 percent swings on thin and recently violent assets happen daily, sometimes hourly, the volatility profile from the low-volume problem. For the math to work, the probability of surviving each window has to be extraordinarily high, and on exactly the assets where the advertised captures are largest, it is not, which is the engine of the 1,500% APR that doesn’t exist.

What sets each side of the ratio, so you can move them. Capture is set by the realized rate, not the snapshot, which decays per funding rate mean reversion and should be projected from persistence rather than annualized fantasy per how to annualize a funding rate, and it accrues on notional per is funding charged on margin or notional. Distance is set by leverage, linearly, and measured against the venue’s mark price rather than the chart you are watching, per mark price versus index price, with forced exits filling at the quote plus a penalty on whatever liquidity exists at the worst moment of the session. Leverage is the only variable you fully control, and it moves the ratio quadratically against you: doubling leverage doubles the capture and halves the distance, a four-fold deterioration in the geometry of the trade.

The discipline that falls out is almost embarrassingly simple: never evaluate a funding trade without both numbers on the same screen, expected capture over your realistic holding window against liquidation distance at your actual leverage, expressed as the ratio between them. Set a maximum ratio you will accept and size leverage backward from it, rather than sizing from the yield and discovering the distance later. The whole category of failure in why delta-neutral positions still get liquidated is downstream of skipping this habit, and putting these two numbers together on every row is one of the founding design decisions of the screener, because a tool that shows you the capture without the distance is not showing you the trade.
