Bitcoin’s market relationships with the dollar index, U.S. equities and gold weakened ahead of Wednesday’s Federal Reserve interest-rate decision. CoinMarketCap data showed its short-window correlation with the dollar index falling to +0.08 from -0.54 over 30 days, while correlations with the S&P 500, Nasdaq and gold also declined. CoinMarketCap research head Alice Liu attributed the decoupling to traders’ focus on the Clarity Act after it failed a key procedural vote in the Senate on Tuesday, diverting attention from macroeconomic factors.
