Investors added more than $166 billion to US money market funds during the week ending October 7, 2026. This massive weekly inflow, the largest since April 2020, propelled total assets in money market funds past the $8 trillion mark.

The surge comes as institutional and individual investors seek low-risk options offering attractive short-term returns. With expectations of further Federal Reserve interest rate hikes and ongoing inflation concerns, market participants are choosing ultra-short instruments over longer-duration bonds. Cash and ultra-short bonds also maintain virtually zero correlation with stocks, helping diversify traditional equity portfolios.

Growth in exchange-traded fund options has further fueled demand. Specialized products like the ProShares GENIUS Money Market ETF (IQMM) have accumulated over $19 billion in assets. Other popular cash management vehicles include the iShares Prime Money Market ETF (PMMF) and JPMorgan 100% U.S. Treasury Securities Money Market ETF (JMMF). Looking ahead, investors should watch upcoming central bank policy choices and broader market yield movements to gauge how long cash products remain attractive.
