According to BlockBeats, on September 6, investors injected cash into U.S. money market funds for the fifth consecutive week, the latest sign of strong demand ahead of a potential interest rate cut by the Federal Reserve.

About $37 billion flowed into U.S. money market funds in the week ended Sept. 4, bringing recent inflows to about $165 billion, according to the Investment Company Institute.

Total assets rose to a record $6.3 trillion from $6.26 trillion the previous week.Despite the strong demand, debate is heating up over whether money market funds will remain popular once U.S. policymakers start lowering interest rates.
