US spot bitcoin ETFs bleed $450 million as Senate kills market structure bill
US spot bitcoin exchange-traded funds shed $450.33 million on Tuesday, the heaviest single-day outflow since June 25, according to data from SoSoValue. The withdrawal came within hours of the US Senate’s failure to advance the Digital Asset Market Clarity Act, a procedural defeat that has effectively ended any prospect of comprehensive market structure legislation clearing the chamber this year.
The bill fell roughly 10 votes short of the 60 needed to proceed. Notably, among those voting against the motion were seven Democrats who had spent months negotiating the text, a sign that even bipartisan goodwill built over months of drafting could not survive the final vote. With Congress expected to be under split control in January, the legislative window for crypto market structure reform has closed for the foreseeable future.
Bitcoin itself has proven comparatively resilient. The largest cryptocurrency trades at $75,679, little changed since midnight UTC, though it sits roughly 8% below its Sept. 4 high. Its 24-hour decline of 1.7% masks sharper damage elsewhere in the market, particularly among tokens whose fortunes are most directly tied to US regulatory treatment.
The CoinDesk 20 Index held its losses, dipping less than 0.1% since midnight after falling 4.6% on Tuesday in the steepest single-day decline since June 5. Of the CoinDesk 100 constituents, a full 95 lost value over the past 24 hours, a breadth of selling that underscores how indiscriminate the rout has been.

Regulatory-sensitive tokens bear the brunt
The starkest divide in this selloff is between bitcoin and the tokens that investors had priced as direct beneficiaries of favourable US regulation. Stellar (XLM) fell 9.6% over 24 hours to $0.1811, while XRP lost 8.1%. Both have long traded as proxies for legislative and judicial progress on digital asset classification in the United States, and both reacted violently to the Clarity Act’s demise.
XRP has dropped nearly 10% alongside a slight uptick in futures open interest, although that open-interest tally remains well below record highs, indicating overall positioning is still light. The combination of falling prices and rising open interest is typically read as new short positions being established rather than long capitulation.
Traditional markets offered no such drama. Nasdaq 100 index futures added 0.33%, gold rose 0.88% and silver climbed 1.37%, while the Dollar Index stood unchanged. The divergence is instructive: this was a crypto-specific repricing of regulatory risk, not a broad risk-off episode driven by macro conditions. When equity futures edge higher while 95 of the top 100 digital assets fall, the selling has a identifiable cause, and on Tuesday that cause sat in the Senate chamber.
Derivatives market flashes warning signs as liquidations mount
The forced deleveraging was severe. Leveraged futures positions worth more than $570 million were liquidated over the past 24 hours, the most since Aug. 22, though still well short of the washouts seen in early February and early June. Those earlier episodes coincided with deeper market stress, suggesting Tuesday’s flush, while painful, has not yet reached systemic proportions.
The taker long-short volume ratio flipped bearish, with shorts accounting for 51.5% of flow over 24 hours. Takers, who lift offers or hit bids at available prices and thereby drain liquidity, have turned aggressive on the sell side.
Bitcoin’s own derivatives positioning tells a cautionary tale. The cryptocurrency dropped 1.4% over 24 hours even as futures open interest ticked up to 688,000 BTC from 676,000 BTC. That combination is widely read as a short bias: traders adding bearish bets into the decline. Bitcoin’s 24-hour open-interest-adjusted cumulative volume delta (CVD) is negative, a sign that more shorts are being executed at the prevailing market price rather than via passive limit orders.
Perpetual funding rates, however, point to lingering optimism among some traders, a wrinkle that could set up further turbulence in either direction.
On Hyperliquid, the trader long/short ratio has pulled back slightly to 2.53 from 2.71, which had been the highest reading since early October 2025, when bitcoin last traded at record highs above $120,000. Even after the retreat, there are still more than two longs for every short, pointing to considerable bullish leverage that could face liquidation if prices keep sliding. That overhang of stale longs is arguably the market’s most fragile element in the days ahead.
The options market adds nuance. Both bitcoin and ether 30-day implied volatility indexes, BVIV and EVIV, remain calm within recent ranges and well below year-to-date peaks, a sign that traders are not pricing a volatility spike around the US rate decision. Yet skews tell a different story. Bitcoin one-week and one-month options skews are positive and rising, a sign of growing demand for puts and downside protection, with the one-week skew hovering around 5.76% and the one-month around 6.33%. Ether skews point in the same direction.
Options volumes split the difference. The most-traded bitcoin options over the past 24 hours were mostly calls, led by the $79,000 strike, suggesting some traders are positioning for a rebound. In ether, however, the top five most-traded options were all puts, a purely defensive posture.
Fed decision looms as attention shifts from Congress
With the legislative calendar now a dead end, attention switches to the Federal Reserve, which announces its interest-rate decision later today. An increase had been the market’s base case going into the meeting, though the calm in implied volatility suggests the crypto market has largely priced the outcome.
That calm may prove deceptive. A market carrying more than two longs for every short on major venues, with negative CVDs across XRP, ETH, TRX, DOGE, XLM and SHIB, and with aggressive selling in the derivatives market across the board, is not a market positioned for disappointment. Funding rates also paint a bearish picture for ETH, XLM, TRX, SOL, BCH, ADA and LINK, and that setup argues for caution around a deeper decline.
The $570 million in liquidations could easily be a first instalment rather than a final tally if the Fed surprises, or if bitcoin loses the $75,000 area that has so far held.
Amid the wreckage, two tokens moved against the tide. Arbitrum (ARB) added 16% to $0.1637 after Standard Chartered forecast the token could reach $10 by the end of 2030, roughly 70 times the current level, citing revenue from Robinhood Chain and the growth of tokenized assets. The bank’s near-term target is a more restrained $0.50 by the end of this year. Synapse (SYN) more than doubled to $0.1787 for no apparent fundamental reason, though the composition of the move raises questions, with futures volume of $310.64 million over 24 hours suggesting speculative froth rather than organic demand.
What the outflow signal means from here
The $450 million ETF outflow matters beyond its headline size because it marks the first major institutional retreat since June, and it arrived on a policy event rather than a price collapse. Bitcoin held its ground far better than the regulatory-sensitive altcoins, yet ETF investors, who tend to be the most policy-aware cohort in the market, voted with their feet within a single session. That suggests institutional conviction in crypto’s US legislative path was more load-bearing for flows than many assumed.
The legislative arithmetic makes a quick revival unlikely. The Clarity Act’s failure, with seven negotiating Democrats voting against cloture, plus split congressional control from January, means market structure reform is now a 2025 story at the earliest. In the interim, tokens that traded as regulatory proxies, XLM, XRP and their peers, may find their former catalysts unavailable, leaving them more exposed to flows and momentum than fundamentals.
The bullish leverage still embedded in the system, more than two longs per short on Hyperliquid, is the variable to watch. If the Fed delivers its expected hike and bitcoin stabilises near $75,000, the market may digest the legislative loss and move on, as options traders betting on $79,000 calls appear to expect. If not, Tuesday’s liquidations and ETF outflows may prove to be the opening chapter of a longer deleveraging.
For now, the burden of proof sits with the bulls, and Congress has just made their case considerably harder to argue.
