Funding arbitrage risks: rate flips, liquidation, ADL, depegs and exchanges

Two opposite positions cancel out price moves but do not protect against anything else. We go through the risks that made delta-neutral positions lose money — from negative funding to the October 10, 2025 crash, when auto-deleveraging closed hedges and the collateral stablecoin on Binance was worth less than 66 cents.

A delta-neutral position (lesson 2) protects against the direction of price — and nothing else. Everything else remains: the rate, margin, exchanges, stablecoins. This lesson goes through the risks in order, with real cases when they hit.

Funding arbitrage risks
RiskWhat happensHow to reduce it
Rate sign flipThe rate you were receiving drops to zero or reverses, and the position starts payingAn exit rule set in advance, an alert on the spread narrowing, checking rate history
Liquidation of one legA sharp price move eats the losing leg’s margin; the other leg’s profit on another exchange does not helpLow leverage, a margin buffer, a price-move alert
Auto-deleveraging (ADL)The exchange force-closes profitable positions to cover liquidations — the hedge falls apartLow leverage, the ADL indicator on the position card, neutral-position modes where available
Collateral depegThe margin stablecoin loses value on a specific exchange, margin melts, liquidations triggerMargin in the contract’s main coin, no exotic or yield-bearing stablecoins
Price divergence between exchangesIn a panic, prices on exchanges diverge by percent and the price spread eats paymentsLiquid coins, a margin buffer, no entries in the middle of volatility
Interval or cap changeA leg starts receiving or paying more often and the return math breaksWatch exchange announcements, recalculate the setup
Delisting and exchange closureThe contract is force-settled, the exchange leaves the marketWatch announcements, do not keep everything on one venue
Deposits and withdrawalsTransfers are suspended; a transfer on the wrong network loses the coinsA reserve on both exchanges, checking network and memo before withdrawing
Liquidity and slippageA thin book: entry and exit at worse prices, squeezesLarge coins, size based on order book depth

Rate sign flip

Funding is payment for a market imbalance, and imbalances pass. According to Ethena, over the three years to the end of 2024 average funding was 7.8% a year for BTC and 9.15% for ETH, but it was negative on 15.9% and 17.5% of days, and the longest negative streak lasted 13 days. Individual coins reverse much faster: an extreme rate can disappear within one or two payments.

Liquidation of one leg: a scenario

Perp + perp: a long on exchange A, a short on exchange B, $1,000 of margin on each, 5× leverage — a $5,000 position per leg. The short is liquidated after roughly a 19.5% price rise.

  1. 1

    The price rose 15% in an hour

    The short on B lost $750 of its $1,000 margin, and the long on A gained the same. Overall the position is neutral, but the profit sits on A while margin is running out on B.
  2. 2

    The short can only be saved on exchange B

    Add margin from the reserve on B or cut both legs. Moving profit from A takes time — withdrawal, network, confirmations — while liquidation triggers at the mark price immediately.
  3. 3

    The price reached +20%

    The short is liquidated: almost all of the $1,000 margin plus the liquidation fee is gone. The long stays open without a hedge — if the price pulls back, its profit disappears too.

The lesson: in perp + perp, each leg must withstand price moves on its own. High-funding coins are often the most volatile — for them, leverage above 2–3× turns arbitrage into a bet that no sharp move will happen.

Auto-deleveraging (ADL)

When a liquidated position cannot be closed in the market and the exchange’s insurance fund cannot absorb it, ADL kicks in: the exchange force-closes positions on the opposite side at the bankruptcy price. On Binance the queue is ranked by profit and effective leverage — the most profitable and most leveraged positions go first. In a delta-neutral setup that is exactly your profitable leg: it gets closed while the losing one stays open.

Some exchanges lower ADL priority for hedged positions: Bybit has a Delta Neutral Mode, and OKX has an account mode for delta-neutral strategies that explicitly mentions funding arbitrage. They are usually available to VIP tiers and require cross or portfolio margin, and even then ADL is not ruled out in an extreme market.

October 10, 2025: a stress test for neutral positions

  • The market liquidated about $19 billion of positions in a day — the largest crash on record according to Coinglass. Perpetual open interest fell 43%, and 57% on Hyperliquid.
  • ADL kicked in on some venues. According to BitMEX’s annual report, auto-deleveraging closed market makers’ short hedges against spot, leaving them with naked spot in a falling market.
  • Prices on exchanges diverged: according to a Bitwise portfolio manager, the ETH price gap between Binance and Hyperliquid at times exceeded $300.
  • The USDe stablecoin on Binance fell below 66 cents. Positions using it as collateral were liquidated; Binance later compensated affected users for losses between 21:36 and 22:16 UTC.

A stablecoin depeg in your margin

An exchange values collateral at its own price. If the margin stablecoin loses value on a specific venue, margin melts even if the position itself is neutral. That is what happened with USDe on Binance in October 2025. In March 2023, USDC dropped to $0.88 after Circle disclosed that $3.3 billion of its roughly $40 billion in reserves sat at the failed Silicon Valley Bank. Keep margin in the contract’s main coin (USDT for USDT contracts) and do not use exotic or yield-bearing stablecoins for hedges.

Intervals, delistings and the exchanges themselves

Exchanges change contract rules on the fly. On October 24, 2026, Bitget moved ARKUSDT from 4-hour to hourly funding; Binance and Gate move a contract to hourly funding when the rate hits its cap. A contract can be delisted with forced settlement, and an exchange can leave the market: BitMEX, the creator of the perpetual swap, delisted and settled XBTUSD and its other main contracts on September 16, 2026 and stopped trading on September 23. Watch both exchanges’ announcements and do not keep all your capital on one venue.

Frequently asked questions

Is funding arbitrage risk-free income?

No. Price neutrality removes only directional risk. Rate sign flips, liquidation of one leg, auto-deleveraging, collateral depegs, price divergence between exchanges and exchange risks all remain.

What is ADL in simple terms?

Auto-deleveraging: when a liquidation cannot be closed in the market and the insurance fund cannot cope, the exchange force-closes the most profitable and leveraged positions on the opposite side. In a hedge, the profitable leg gets hit and the other one is left unprotected.

Why is the short liquidated if the long on another exchange is in profit?

Margin on exchanges is separate. The long’s profit on exchange A does not top up the short’s margin on exchange B, and moving money takes time. Liquidation triggers at the mark price immediately.

How do I protect against a stablecoin depeg?

Keep margin in the contract’s main coin (USDT for USDT contracts), do not use exotic or yield-bearing stablecoins as collateral, and leave a margin buffer.

What should I do if an exchange announces a contract delisting?

Close both legs in advance, before the forced settlement date: after it one leg disappears and the other is left unhedged.
