Composition and Recent Flows
Government funds comprise 82.5% of total money market fund assets, underscoring the defensive tilt of investor positioning. In the most recent weekly data, government funds grew by $7.76 billion, while prime funds added only $112 million. Tax-exempt funds shed $2.64 billion, suggesting municipal investors are also pulling back.
Institutional investors account for approximately 61% of total MMF assets. This concentration means large pools of capital are moving in tandem, amplifying the impact of shifts in risk appetite across the broader financial system.
Longer-Term Trajectory
The current $7.89 trillion represents substantial growth from earlier in 2025. Money market fund assets hit a record of $7.03 trillion in early March 2025, meaning the pile has grown by more than $800 billion over roughly 16 months. By mid-June 2026, assets stood at $7.92 trillion, putting the latest figures only marginally below that level.
Other trackers report even higher totals. Crane Data pegged total money market assets near $8.4 trillion in early July, suggesting measurement differences across data providers.
The scale matters. Money market funds represent an ocean of liquidity parked on the sidelines of riskier markets. When this cash moves, it flows into equities, credit, or alternative assets. When it doesn't, it signals caution—and potentially tighter conditions for borrowers seeking to access capital markets.
