Can You Earn Yield Just by Collecting Funding?.

Yes, you can earn yield by collecting funding: the payments are real, they settle on a schedule, and a delta-neutral position built to receive them, per what a delta-neutral funding strategy is, converts them into income without a directional bet. The honest qualifications are about magnitude and persistence: the realized yield at safe leverage, after costs, on rates that actually persist, is modest, and the spectacular rates that make harvesting look lucrative are spectacular precisely because they are dislocations, and dislocations decay.

Start with the realistic baseline. The structural resting state of perp markets is the slightly positive rate from what a normal funding rate is, roughly 11 percent annualized flowing to the short side at equilibrium. A standard cash and carry, per cash and carry versus funding arbitrage, harvests approximately that on the majors in normal regimes, minus costs, on fully funded capital. In hot regimes when the whole market runs leveraged-long, the same construction collects multiples of baseline for as long as the regime lasts. That is the real product: a market-neutral yield in the high single digits to low double digits that expands when speculation gets crowded. Honest, collectible, unspectacular.

The spectacular prints are a different animal. A triple-digit annualized rate on some market is an advertisement for a dislocation, and the advertisement works: capital arrives, the crowded side bleeds out, and the rate decays toward baseline through exactly the machinery in funding rate mean reversion. Annualizing the print, per how to annualize a funding rate, tells you what it would pay if it persisted, and it will not persist, which is the entire fiction behind the 1,500% APR that doesn’t exist. The partial exception worth knowing: structural flows, airdrop and unlock hedging pinning a market’s funding deeply negative for weeks, per funding on new listings, are persistent because the payer is hedging rather than speculating and does not care about the toll. Those pockets are genuinely harvestable, and they come bundled with new-listing liquidity, borrow constraints on the inverted leg, and thin books at exactly your exit.

Then the subtractions, which are the difference between projected and realized. Costs on every leg at your actual size. The capital drag of margin, halved across venues if you run the cross-venue version per funding rate arbitrage. Rate risk, since the rate you built the position for can flip sign and turn the harvest into a toll. And the tail: one divergence event on a leveraged construction, per why delta-neutral positions still get liquidated, can return months of collection in an afternoon, which is why position sizing, not rate selection, is where harvesting strategies actually live or die.

The hurdle question completes the honest assessment: market-neutral dollar yield competes with whatever riskless or near-riskless dollar yield exists, stablecoin money markets, treasuries, lending rates. Funding harvesting earns its place only when the realized spread over that hurdle compensates for the operational load and the tail. In crowded bull regimes it clears easily; in quiet regimes it frequently does not, and the discipline to stop harvesting when the spread over the hurdle disappears is most of what separates the desks that run this well from the dashboards that sell it.
