Derivatives Daily: Bitcoin $83,462 and $483M Liquidations on Sep 29

The derivatives market absorbed $483.0M in liquidations over the past 24 hours, including $372.9M of long positions and $110.1M of shorts. At the same time, Bitcoin options were priced around an index level of $83,461.74, while global open interest stood at $127.7B. The combination suggests that bullish positioning remains substantial, but it has already been tested by a meaningful long-side reset.

Long liquidations dominate the leverage reset

The liquidation imbalance is clear across the time windows. The market recorded $213.9M in liquidations over 12 hours, rising to $483.0M over 24 hours. Longs represented the larger share in both periods, with $133.5M of 12-hour long liquidations versus $80.4M of shorts. The four-hour split was also skewed toward longs at $11.0M against $3.4M of shorts.

By coin, BTC led the damage with $132.8M liquidated, comprising $102.3M of longs and $30.5M of shorts across 8,889 events. ETH followed with $103.2M, including $65.7M of longs and $37.5M of shorts across 6,682 events. ZEC, SOL and NEAR added $28.2M, $20.6M and $18.6M respectively. The largest recorded event was an ETH long liquidation worth $11.7M on Binance, followed by a $6.5M BTC long liquidation on the same venue.

Open interest remains elevated beside that flush. The market overview shows $126.7B in total open interest and $225.7B in 24-hour volume across 2,695 coins, while the broader derivatives reading puts open interest at $127.7B. Average funding was positive at 0.0066%, indicating that longs still paid to maintain exposure despite the liquidation wave.

ETF inflows support the larger coins

Institutional flow data remains a constructive counterweight. The latest reported Bitcoin ETF session, dated Sep 25, brought in $134.5M, taking the seven-day total to $3.0B and cumulative flow to $57.6B. Bitcoin ETF assets under management were $108.4B. The daily sequence remained positive throughout the reported seven-session window, although the flow slowed from $999.0M on Sep 21 to $190.6M on Sep 24 and then $134.5M.

Ethereum ETF demand was also positive at $86.9M on Sep 25, with a seven-day sum of $794.4M, cumulative flow of $14.0B and assets under management of $17.8B. The strongest session in that window was $270.0M on Sep 21. These flows favor continued demand for the major coins, even as futures leverage has been shaken out.

Options point to a nearby price magnet

Bitcoin options open interest totaled $30.0B, or 355,852.2 BTC, with $31.8M in 24-hour options volume. The open-interest put-call ratio was 0.5, while the volume ratio was 1.1. The aggregate max pain for the Oct 2 expiry was $83,000, close to the $83,461.74 index price. Near-term expiries cluster around $84,000 on Sep 29, $85,000 on Sep 30, $83,500 on Oct 1 and $83,000 on Oct 2. The Oct 2 expiry carries $2.3B of open interest, the largest listed near-term concentration, with $1.2B in puts and $1.0B in calls.

The sentiment overlay is bullish but no longer comfortable: the Fear & Greed Index is 74, classified as Greed, while the altseason index is 66 and classified as neutral. That mix favors selective strength rather than indiscriminate risk-taking.

Verdict: The tactical bias stays cautiously bullish while Bitcoin holds the $83,000 options max-pain area and global open interest remains near $127.7B. A sustained move above $85,000 would strengthen the upside case, while a break below $83,000 accompanied by falling open interest would invalidate it and signal that the long liquidation cycle is continuing.
