BofA：美元空仓降至 2012 年以来低点，比特币与美元现异常正相关

Core Viewpoint - Investor bearish positions on the US dollar have dropped to the lowest level since 2012, indicating a historically low allocation to the dollar [1] Group 1: Dollar and Bitcoin Correlation - Traditionally, a weaker dollar benefits risk assets like Bitcoin; however, since early 2025, Bitcoin has shown an unusual positive correlation with the dollar index, with a 90-day correlation coefficient reaching 0.60 [1] - If this correlation persists, further declines in the dollar may not necessarily benefit Bitcoin and could instead exert pressure on it [1] - Conversely, if the dollar rebounds due to short covering, Bitcoin may rise alongside it, leading to increased market volatility [1]
