Money Market Funds Record $136 Billion Inflow After Prior Week’s $175 Billion Outflow

Money market funds posted $136 billion in inflows last week, the largest weekly intake since January 2026 and the second-largest weekly inflow since the beginning of 2025. The surge followed $175 billion in outflows in the preceding week, the largest weekly withdrawal on record.

As a result, the four-week average of money market fund flows stands at $45 billion in outflows, the second-largest on record.

The sharp reversal comes after a historic run in markets that prompted shifts in capital allocation.

The preceding week's record outflow had pushed the short-term average to levels rarely seen. Last week's $136 billion inflow erased much of the prior week's move in a single period. Even so, the four-week average of $45 billion in outflows reflects sustained pressure over the recent month.

Investment-grade bonds drew the bulk of the fixed-income allocation. 4 billion inflow into that segment matched the scale of the money market move in relative terms for the year. The data illustrate rapid repositioning by investors.

One week brought the largest recorded withdrawal from money market funds, the next the second-largest inflow in more than 16 months.
