According to The Kobeissi Letter, money market fund assets under management have surged to a record $7.4 trillion, now accounting for approximately 15% of the S&P 500's market capitalization, up from 13% in February (source: The Kobeissi Letter, Twitter, May 5, 2025). Over the past two years, these assets have increased by $2 trillion, indicating a significant shift in capital allocation despite recent Fed rate cuts. For traders, this trend suggests heightened risk aversion and a preference for liquidity, which could lead to lower equity market inflows and increased volatility in both traditional and crypto markets as investors seek safe havens.
