Bitcoin ETF Outflows Hit $450mn as CLARITY Act Stalls in Senate

• BTC-USD
• BLK
• IBIT

U.S. spot Bitcoin funds saw their sharpest reversal in weeks on Sep. 15 as Washington delivered another dose of regulatory uncertainty.

Farside Investors data showed the 12 US spot Bitcoin ETFs posted $450.4 million in combined net outflows yesterday, wiping out the previous session’s $159.9 million inflow.

Fidelity’s FBTC led withdrawals with $214.8 million, followed by BlackRock’s IBIT at $161.7 million and Grayscale’s GBTC at $44.1 million.

The last time Bitcoin ETFs posted such massive outflows was on June 25 ($696.29 million). The timing places the ETF withdrawals alongside a clear regulatory shock, although it does not establish that the vote alone caused investors to redeem shares.

There was another large variable in play. Markets were also preparing for a Federal Reserve decision, with a rate increase widely expected and Treasury yields already putting pressure on risk assets.

Senate vote leaves crypto rules unresolved

The Senate failed to advance the Digital Asset Market Clarity Act after the measure did not secure the 60 votes required to proceed. Only 50 senators voted in favor of advancing the bill, with four Republican senators joining Democrats in voting against it. Senator Thom Tillis changed his vote as a procedural step that preserves the possibility of reconsideration.

The legislation was intended to create a federal market structure for digital assets and clarify responsibilities between the Securities and Exchange Commission and Commodity Futures Trading Commission. Supporters argued that congressional legislation would give crypto companies and investors more durable regulatory rules.

Opponents sought stronger ethics provisions covering elected officials’ financial interests in digital assets, among other changes. Negotiations continued until shortly before the vote but did not produce an agreement.

Redemptions spread to the largest Bitcoin funds

Tuesday’s flows were notable because the selling was concentrated in two of the market’s largest products. IBIT and FBTC together accounted for roughly $376.5 million of net redemptions.

The longer-term numbers remain considerably larger than Tuesday’s move. After the Sep. 15 withdrawals, net flows for September were still marginally positive at about $16.8 million.
