Bitcoin Slides as CLARITY Act Stalls, DeFi Surges, and UK Tightens Crypto Tax

Bitcoin opened July 24 at $65,029.96, extending a multi-day pullback as macro headwinds and fading legislative optimism weighed on investor sentiment. The broader crypto market dropped 1.3% to $2.3 trillion in total capitalization over the past 24 hours, with trading volume reaching $58.9 billion and the Fear and Greed Index sliding to 28, a level that signals deepening caution across the market.

Bitcoin's dominance held firm at 56.6% even as BTC itself shed 1.4% on the day, trading near $64,961. Ethereum fell alongside it, and Solana slipped 2.43% to $76.01. The lone bright spot in an otherwise red session was the decentralized finance sector, which surged 9.8%, while Polkadot and the XRP Ledger Ecosystem led all gainers by market cap.

CLARITY Act Faces Long Odds Before August Recess

A primary drag on Bitcoin sentiment is the uncertain fate of the Digital Asset Market Clarity Act in the U.S. Senate. The bill sat on the Senate Legislative Calendar with no floor vote scheduled and three interlocking disputes still blocking the seven to nine Democratic votes needed to clear the 60-vote filibuster threshold. The Senate breaks for August recess around August 7, leaving only a narrow window analysts have consistently called the last realistic gate for 2026 passage. Polymarket traders are currently pricing the odds of the CLARITY Act being signed into law this year at around 43%.

Senator Cynthia Lummis has warned the legislation could slip as far as 2030 if the recess window is missed. The bill, which passed the House, would formally allocate jurisdiction over digital assets between the SEC and the CFTC, create registration categories for digital commodity exchanges, and add consumer protection requirements. Its failure to advance has rattled investors who had expected regulatory clarity to serve as a price catalyst in the second half of 2026.

Across the Atlantic, the United Kingdom delivered a separate regulatory signal. HM Revenue and Customs recovered over £8 million from 502 crypto investors over two years, and new OECD reporting rules taking effect in 2026 are set to make concealing crypto gains significantly harder. The enforcement push reflects a broader global trend of tax authorities tightening oversight of digital asset holdings, with the OECD framework compelling cross-border data sharing among participating nations.

Also drawing attention today, Argentina's government is weighing a draft proposal that would allow investment funds to hold Bitcoin and permit digital assets to be used as loan collateral. The measure still requires presidential approval and full congressional review before it could become law, but the proposal signals growing institutional appetite for Bitcoin exposure in emerging markets.
