Bitcoin perpetual futures simply closed out the longest stretch of unfavorable funding charges in a decade. In accordance with Ok33 Analysis knowledge cited by CoinDesk, the 30-day common funding price stayed unfavorable for 67 consecutive days — the longest streak in 10 years, eclipsing the run from March to Might 2020.
For brief sellers in BTC perpetuals, that meant roughly 201 separate funding debits — three settlements per day throughout 67 days — chipping away at margin whereas the worth floor sideways to larger.
When the squeeze lastly arrived and quick positions began getting compelled out, one thing uncommon confirmed up within the autopsy. Merchants working equivalent quick positions — similar leverage, similar entry, similar dimension — didn’t all get liquidated on the similar value. Some bought partial closes, whereas others bought wiped. CoinGlass liquidation data confirmed volumes distributed erratically throughout main exchanges within the 48 hours that adopted.
Why 67 Days of Damaging Funding Punishes Brief Positions
Perpetual futures use funding payments to maintain contract costs anchored to identify. The mechanism is easy: when funding is constructive, longs pay shorts. When it’s unfavorable, shorts pay longs. Most main venues settle these funds each eight hours, which over 67 days compounds to 201 settlement factors.
For a brief vendor, every negative-funding settlement is a direct debit from margin. None of it reveals up on the worth chart. The place may be flat and even reasonably worthwhile on a P&L foundation whereas the underlying margin steadiness bleeds — slowly throughout quiet intervals, extra aggressively during times when funding turns deeply unfavorable.
The 2026 streak hit that profile. Funding stayed in red ink while BTC traded between roughly $74,000 and $83,000, drifting larger with out breaking. The worth chart regarded secure. The margin accounts of quick sellers didn’t. By the point the squeeze caught up — coinciding with broader risk-off flows tied to renewed US-Iran tensions — many shorts had been already working with considerably much less cushion than their notional place dimension urged. Roughly $590 million in positions had been unwound within the 24 hours main into early European buying and selling on 18 Might, in accordance with CoinGlass knowledge. That a part of the story has been properly coated. The half that has not is why the identical setup produced completely different outcomes on completely different venues.
Upkeep Margin: The Quantity That Decides Your Liquidation Value
Upkeep margin is the minimal fairness an alternate requires you to carry towards an open place earlier than it force-closes the commerce. The quantity sounds uninteresting. It’s the single most necessary variable separating one venue from one other in the intervening time of liquidation.
Binance at present runs a 0.5% upkeep margin on commonplace BTC perpetual positions in its lowest tier, with the ground rising as place dimension will increase. Different main exchanges run tiered constructions with completely different beginning factors and completely different escalation curves. The variations look trivial in isolation. They don’t seem to be.
On a 20x leveraged BTC quick, a 0.1% distinction in upkeep margin shifts the liquidation value by roughly 2% of the underlying. For a place opened round $80,000, that’s the distinction between a liquidation set off close to $83,200 and one close to $84,800. In a market that moved shut to eight% over a compressed window, that’s the distinction between getting force-closed and surviving the wick.
These tiers are public. They sit in alternate documentation, usually a number of clicks deep. The Leverage.Trading breakdown of crypto futures liquidation mechanics compares them throughout the main venues. Most retail merchants by no means look.
Partial vs Full Liquidation: The Engine Design Most Merchants Ignore
The second mechanical variable is how the liquidation engine itself behaves as soon as the set off is hit. There are two broad designs in use throughout main venues, and so they produce very completely different outcomes throughout quick strikes.
Binance and Bybit use partial liquidation. When a place breaches upkeep margin, the engine reduces place dimension in increments — closing a proportion of the commerce, permitting the remaining place to soak up the subsequent value tick, and solely escalating to full closure if margin retains deteriorating. The dealer takes injury however could retain a part of the place if value stabilises.
A number of different main perpetuals venues run full-position liquidation. There isn’t a incremental step. The set off hits and the complete place closes on the subsequent out there market value.
Within the circumstances that prevailed through the Might squeeze, with BTC shifting sharply throughout quick home windows and order books thinning, the design selection was decisive. Equivalent positions at equivalent entries on partial-liquidation venues skilled partial closes. The identical trades on full-close venues had been wiped in a single transfer. The dealer had no enter within the end result past their selection of alternate weeks or months earlier.
This isn’t a uncommon or esoteric situation. It’s the usual distribution of outcomes throughout any volatility occasion massive sufficient to set off cascading liquidations.
Funding Price Caps and the Compounding Impact
The third variable is much less seen however issues most over lengthy funding regimes just like the one simply ended. Per-interval funding price caps decide the utmost quantity that may be debited or credited in a single 8-hour settlement.
Caps should not uniform throughout exchanges. Most main venues impose ceilings on how unfavorable funding can go in any single interval, however the ceiling values differ — generally by elements that look small per settlement and enormous in mixture. Over 201 sequential settlements through the 2026 streak, these variations compounded.
The result’s {that a} quick place of equivalent notional worth, opened concurrently throughout two venues, can arrive in the intervening time of squeeze with materially completely different margin balances. The dealer who selected the venue with tighter funding caps walks into the liquidation occasion with extra cushion. The dealer who selected the venue with looser caps walks in already weakened.
“Three Numbers That Matter Extra Than the Commerce”
Anton Palovaara, founder at Leverage.Trading, sees the identical blind spot repeatedly in his work with retail and prop merchants:
“Earlier than opening a leveraged place, there are three numbers that matter greater than the commerce: upkeep margin at your dimension, whether or not the alternate makes use of partial or full liquidation, and the funding price cap. Most merchants ignore all three. These numbers resolve whether or not you get a partial shut or get worn out on the identical transfer. They’re public, buried in alternate docs, and virtually no one seems.”
Why Change Choice Is a Threat Query, Not a Charges Query
The traditional strategy to selecting a derivatives venue weighs maker-taker charges, unfold high quality, listed product vary, and withdrawal frictions. These matter. They’re additionally the fallacious main standards for any dealer who plans to make use of leverage.
What the 67-day funding regime and its aftermath confirmed — and what the exchange-level CoinGlass liquidation breakdown makes legible — is that the identical place opened on the similar time throughout two venues won’t produce the identical end result throughout a volatility occasion. Upkeep margin tiers, mark value methodology, liquidation engine structure, and funding cap constructions all sit upstream of any commerce resolution. As soon as a place is open, none of those are negotiable. They’re the bottom circumstances a dealer accepts the second they fund the account.
Most protection of the squeeze framed it as a positioning story — too many shorts caught on the fallacious aspect of a market that refused to interrupt decrease. That framing is appropriate so far as it goes. It doesn’t clarify why the distribution of ache was uneven throughout venues that each one noticed the identical value motion.
The exchange-level knowledge tells a extra helpful story. The identical commerce, positioned on the similar time, produced completely different outcomes on completely different platforms. Not due to market judgement, however due to how every venue holds margin, caps funding, and executes compelled closes.
For merchants getting ready for the subsequent leveraged cycle — and historic evaluation throughout six comparable unfavorable funding regimes since 2018 reveals all six delivered constructive ahead returns at 90 days, with win charges of 83% to 96%, per Ok33’s knowledge — the lesson is upstream of any particular commerce. Learn the alternate earlier than inserting the place. Evaluate upkeep margin tiers on the dimension you plan to commerce. Verify whether or not the liquidation engine reduces or closes. Test the funding cap construction. The Leverage Buying and selling crypto futures liquidation information lays out a framework for working that comparability earlier than capital is dedicated, not whereas a place is being force-closed.
The 67-day streak is now a part of the historic document. The subsequent one is already being arrange by positioning that none of us can see but. The one variable a dealer can absolutely management between at times is which venue they’re on when it arrives.
