Bitcoin and Ethereum prices have declined following the release of U.S. PCE inflation data, which has led to institutional corrections and portfolio adjustments. On September 23, 2025, BlackRock executed a significant $980 million sell-off, adding pressure to the market. The market saw over $1.6 billion in leveraged Bitcoin and Ethereum positions liquidated, while ETF inflows decreased, raising concerns about liquidity and volatility. This development highlights the cryptocurrencies' sensitivity to macroeconomic data, reinforcing their roles as proxies for market volatility.
