US money market fund assets slip to $7.89 trillion as investors park cash in safe havens

Nearly $7.9 trillion is sitting in money market funds right now. According to the Investment Company Institute, US money market fund assets came in at $7.89 trillion, reflecting a slight decrease from recent levels. The number is down modestly from the $7.95 trillion recorded for the week ended July 8, 2026, but still represents an ocean of liquidity parked on the sidelines of riskier markets.

Where the money is flowing

Government funds make up roughly 82.5% of total money market fund assets. Institutional investors account for approximately 61% of total MMF assets.

In the most recent weekly data from ICI, government funds grew by $7.76 billion while prime funds added a comparatively modest $112 million. Tax-exempt funds, meanwhile, shed $2.64 billion. The net effect was a $5.23 billion weekly increase to the $7.95 trillion figure before the latest dip to $7.89 trillion.

Crane Data, another firm tracking this space, pegged total money market assets even higher, near $8.4 trillion in early July. The discrepancy comes down to methodology and which fund types get counted.

The bigger picture: a mountain that keeps growing

Total MMF assets hit a then-record of $7.03 trillion back in early March 2025. In roughly 16 months, the pile grew by more than $800 billion. By mid-June 2026, assets stood at $7.92 trillion, and they’ve been hovering in that neighborhood since.
