Record Money-Market Growth Faces Rate Cut Shift

Rising Money-Market Fund Assets and the Potential Shift in Investor Behavior

The U.S. Federal Reserve is anticipated to lower interest rates this week, which could significantly impact investor behavior, particularly regarding money-market funds. These funds have seen a surge in assets over the past few years, with total assets reaching $7.302 trillion for the week ending September 10. This figure reflects a steady increase that has been ongoing for some time, but recent trends show a more pronounced shift.

Institutional investors have played a major role in this growth, contributing an impressive $42.58 billion to institutional money-market funds during the same period. This stands in stark contrast to the modest $1.24 billion increase in retail funds. Shelly Antoniewicz, chief economist at the Investment Company Institute (ICI), notes that such increases often occur before quarterly corporate tax payments are due. Additionally, these inflows may also be influenced by expectations of the Fed’s upcoming rate cuts.

Antoniewicz explains that when the Fed reduces short-term interest rates, institutional investors tend to favor money-market funds over direct investments in short-term instruments. This is because the yields from these funds may lag behind the federal-funds rate, making them a more attractive option for managing cash.

Since 2022, when the Fed began raising rates rapidly, money-market funds have become increasingly appealing to investors. At one point, some funds offered returns as high as 5%, and even after last year's rate reductions, they have remained competitive. As of September 11, the Crane 100 Money Fund Index showed an interest rate of 4.1%, according to Crane Data. However, if the Fed continues its rate-cutting cycle, these rates could decrease further.

This significant amount of capital parked in money-market funds has led many investment professionals and analysts to believe that there is ample "dry powder" available to sustain the current bull market in stocks. Jeff Buchbinder, chief equity strategist at LPL Financial, wrote that if the Fed delivers rate cuts in line with market expectations, this capital could soon be deployed into equities.

Buchbinder suggests that a meaningful reduction in rates could alter the dynamics of money-market funds, potentially leading to a shift in investor behavior. If investors move their money out of these funds and into stocks, it would end the unusual trend of money-market assets rising alongside stock prices.

Gene Goldman, chief investment officer at Cetera Financial, believes that while near-term factors like high valuations might pressure equity prices, the cash equivalents held by investors—such as money-market funds and savings accounts totaling a record $27 trillion—are still a valuable resource. He emphasizes that this cash is essentially waiting for better valuations, supporting a buy-the-dip strategy.

However, there are several reasons to approach this potential shift with caution. First, as Buchbinder points out, it may take multiple rate cuts before investors make significant changes to their portfolios. Historical data shows that money-market fund outflows typically begin about 12 months into a rate-cutting cycle.

Additionally, investor behavior is influenced by their expectations regarding the stock market and the economy. If equity valuations appear too high, investors might prefer the stability of money-market funds, even if the returns are lower. The current economic climate, including a cooling jobs market, could also affect investor decisions, with many preferring to maintain a cash buffer for security.

Lastly, inertia plays a crucial role in investor behavior. Andy Reed, head of behavioral economics research at Vanguard, highlights that cash often remains in accounts like IRAs because investors forget to invest it. This phenomenon, known as “stuck cash,” can prevent investors from acting on their intentions, even when they recognize better investment options.

Reed explains that making informed investment decisions requires not only awareness of better options but also the motivation to act. Inertia can hinder all three steps of this process, making it challenging for investors to shift their capital even when conditions seem favorable.
