Bitcoin's short-window correlation with the Dollar Index has fallen to +0.08 from -0.54 over the past 30 days, while its link to the S&P 500 dropped to 0.43 from 0.75 yesterday, and to the Nasdaq to 0.30 from 0.60. CoinMarketCap's head of research, Alice Liu, attributes this disconnect to traders' recent focus on the failed Senate procedural vote for the Clarity Act regulation, diverting attention from broader economic factors. The Fed is widely expected to raise interest rates by 25 basis points today, a move largely priced in by the market.
