S&P 500, Money Market Funds Both Hit Record Highs as Investors Await Rate Cuts Below 3%

According to Bloomberg analyst Eric Balchunas, as of late June 2026, the S&P 500 and money market funds (MMF) have reached record highs simultaneously, creating an unusual structure of elevated equity valuations alongside elevated cash reserves. The analyst notes that investors hold substantial "dry powder" yet may require interest rates to fall below 3% to trigger significant equity inflows, as current 4% money market yields make stable-value MMF products more attractive than alternative fixed-income investments.

Balchunas attributes the shift partly to reduced investor confidence in traditional bonds following the 2022 bond market downturn, which saw broad-based indices like AGG decline approximately 13%, with ongoing macroeconomic uncertainty further supporting the preference for cash holdings.
