US Senate Blocks Clarity Act as Bitcoin ETFs Lose $450 Million in a Day

The U.S. Senate blocked a key procedural vote on the Clarity Act, the bill meant to set federal rules for crypto markets. The market reacted almost instantly. Bitcoin dropped below $76,000, and Bitcoin ETFs lost $450 million in a single day. That is the largest outflow since June, and the biggest funds took the hardest hit.

The vote that stopped the bill

On Tuesday, senators voted 49 to 50 on cloture, a procedure that limits debate and opens the door to considering the bill on its merits. Passing required 60 votes. The Clarity Act was meant to split oversight between the Securities and Exchange Commission and the Commodity Futures Trading Commission and effectively legalize most crypto activity in the US.

All Democrats present voted no, including Elizabeth Warren and Elissa Slotkin, along with Republicans Susan Collins, Josh Hawley and Jerry Moran. Senator Thom Tillis initially voted yes but switched his vote for procedural reasons. Most Republicans, including Tim Scott and Cynthia Lummis, backed the bill.

Ahead of the weekend, Republicans put forward an updated text with 126 changes requested by Democrats: a requirement for officials to place crypto holdings in a blind trust, authority for state attorneys general to help enforce the restrictions, and a "circuit breaker" meant to guard against deposit outflows tied to stablecoin yield. Democrats still sent a counteroffer late Monday with additional demands, and Republicans called it yet another case of moving the goalposts.

"It's over."

Price reacted before the evening was over

Bitcoin lost 2.5% over 24 hours and traded in a $75,700-76,385 range. The drop also affects anyone planning to sell Bitcoin for hryvnia in the coming days. At the current rate, the payout will land noticeably lower than a week ago.

The failed vote piled more pressure onto an already cautious market. Traders read the blocked cloture as a signal that regulatory uncertainty in the US will drag on longer than expected over the summer.

Which funds took the biggest hit

Data from Farside shows a clear split in losses across the 13 US-listed Bitcoin ETFs on Tuesday.

• Fidelity's FBTC lost more than any other fund, $214.8 million
• BlackRock's iShares Bitcoin Trust shed $161.7 million
• Grayscale's Bitcoin Trust ETF fell by $44.1 million
• ARKB and BITB combined lost less than $30 million

Just the day before, the same funds pulled in $159.9 million. The swing in a single day was striking, and it showed how sharply institutional money reacts to news out of Capitol Hill.

Pressure on Coinbase and crypto companies

The failed vote also hit shares of public crypto companies. Saxo analysts believe Coinbase will feel the fallout harder than rivals, given how much the exchange depends on US regulatory clarity. The Commodity Futures Trading Commission, for its part, said it will start rolling out its own crypto rules using existing authority rather than wait for Congress.

The stablecoin yield dispute remains one of the main sticking points. Eight banking trade groups, including the American Bankers Association, called the new circuit breaker inadequate because it would only kick in after substantial deposit flight had already occurred. Coinbase CEO Brian Armstrong, for his part, accuses banks of trying to suppress competition from stablecoins.

What comes next for the Clarity Act

Senate leaders could in theory bring the bill back for another vote. Time is short. Roughly three weeks of working days remain before the fall session gives way to midterm campaigning. Even if senators pass an updated text, the bill would have to go back to the House, since the Senate version differs from what representatives already approved.

Both chambers need to agree on identical text before the bill can reach the president's desk. The next three weeks will show whether Democrats and Republicans can find common ground on ethics restrictions and stablecoin payouts.
