Altcoin open interest drops $8 billion as hedging doubles

According to Decrypt, total crypto market capitalisation slipped 2.5% to $2.8 trillion over the day. Ethereum ended at a $289 billion market cap, XRP at $82.4 billion and Solana at $60.6 billion. Bitcoin, worth $1.6 trillion, lost 3.1% over 24 hours and 2.6% over seven days.

The backdrop was macro. Annual US CPI for September came in at 3.7%, and users of the prediction market Myriad, run by Decrypt's parent Dastan, put a 28% chance on an October rate hike.

Luke Nolan, senior research associate at CoinShares, told Decrypt that high-beta assets took the hardest hit. He also pointed to the US dollar at a near 18-month high, and said crypto tends to move against the dollar index over the medium term. In his words: "Alts are typically more sensitive to financial conditions, and tightening affects the premise of liquidity expanding."

The most useful number for derivatives traders came from Max Shannon of Bitwise Europe. He told Decrypt that altcoin futures open interest, excluding Ethereum, has fallen by $8 billion since October began. Shannon read that as traders locking in gains after a strong run.

Open interest counts contracts still open. When it falls with price, positions are usually being closed rather than new shorts piling in. That can be profit-taking or forced liquidation; the figure alone does not say which.

Options showed the same defensive turn. Nick Forster, founder of the options venue Derive.xyz, said hedging activity on his platform doubled. He added that whales pulled back on bullish bets placed in spring, and described the mix of dropped long-dated upside bets and heavy short-term hedging as a sharp regime change among institutions.

Spot fund flows lined up too. Shannon said ETH beat bitcoin for three months in a row, the first such streak since March 2021, and holders have been taking profits since. Ethereum ETFs logged net outflows on 11 straight sessions, $782.8 million in all, before a brief inflow on Tuesday. CoinGlass data show $129.5 million more in net outflows since then, per Decrypt.

Coinlytic's daily-close data, from Bybit as of Oct. 16, shows how far each asset has come off its recent peak. These are price figures, not funding readings.

• ETH closed at $2,435, 12.3% below its 90-day high close of $2,776 from Sept. 21, and 4.7% below its 50-day average of $2,554.
• XRP closed at $1.33, 15.3% below its 90-day high close of $1.57 from Sept. 22, and 6.2% under its 50-day average.
• SOL closed at $105.13, 13.9% below its 90-day high close of $122.14, and 3.9% under its 50-day average.
• BTC closed at $82,089, only 5.2% below its 90-day high close and 1.0% above its 50-day average of $81,293.

The gap is the point. Bitcoin sits 81% of the way up its 90-day range, while ETH sits at 63% and XRP at 58%. Longs opened in altcoins near the September highs carry deeper unrealised losses than similar bitcoin longs. That is where margin pressure tends to concentrate when volatility returns.

Shannon said altcoins usually track bitcoin closely in stress, and may move in step with BTC near term but with bigger swings. For a leveraged trader, that is a volatility risk statement. Questions worth re-checking in a written plan:

• If bitcoin moves a given amount, has my position size been set for the larger move an altcoin may make?
• Is my liquidation price far enough from the market to survive a day like Oct. 15, not just an average day?
• Do I know whether falling open interest in my market came from profit-taking or forced closures?
• Am I paying for protection, or am I the one others are hedging against?

Nolan told Decrypt he cannot call a bottom for altcoins and wants October hike expectations to fade, and he sees arguments in both directions. That leaves rate expectations as the main macro input to track.

In derivatives, watch whether altcoin open interest keeps shrinking or rebuilds, whether hedging demand on venues such as Derive stays high, and whether Ethereum ETF outflows continue. Open interest rebuilding in a falling market would point to new shorts, a different kind of crowding.
