With just a week remaining until the highly anticipated September Federal Open Market Committee (FOMC) meeting, Thursday’s results for August is the last major hurdles lying between the expected resumption of the FOMC easing cycle.
Fed fund futures have fully priced a 0.25% rate reduction next Wednesday — and are currently priced for a full percentage point of easing before Federal Reserve (Fed) Chair Jerome Powell’s term ends in May (with roughly two-thirds of this priced in for 2025). Baring the unlikely chance Fed Chair Powell warns of a recession or outsized urgency around the labor market, U.S. equities are likely poised to build on year-to-date gains should central bankers deliver on Powell’s hint of a policy change at last month.
Dry Powder for Wall Street Bulls?
In addition to strong corporate profits, fiscal policy, and a resilient economy, potential rate cuts could be a necessary catalyst for stocks to extend their rally off April 8 lows as rate cuts historically are stimulative for stocks absent a recession (as we noted in our September 8 Weekly Market Commentary). As an honorable mention to these direct themes underpinning the future of the bull market, the resumption of the monetary policy easing cycle could also provide additional longer-term tailwinds for equity markets under the surface.
Assets in money market funds have been on the rise since 2022, and if rate reductions are delivered roughly on pace with market expectations, this capital currently on the sidelines is likely to be called into the big game. The meaningful move lower in rates currently priced in would shift the arithmetic around money market funds, diminishing earnings and potentially leading investors to re-deploy capital — ending the unusual trend of money market assets rising alongside equity prices.
As shown in the “Money Market Assets Typically Do Not Rise Alongside Equities” chart, rises in the market cap of the Index (which represents roughly 98% of the investable U.S. equity market) tends to correlate with declining or stable levels of money market fund assets. This has not been the case since 2022 due to the Fed’s cycle and “higher-for-longer” stance, which increased the attractiveness of money market funds.

Paired with U.S. equity positioning still only moderately above neutral relative to developed and emerging markets following this spring’s so-called “tariff tantrum” selling, elevated and rising money market funds indicate that investors may not be fully invested — suggesting next Wednesday’s Fed rate decision could be an early domino to fall in igniting additional support for the bull market.
However, the effects of investors potentially re-deploying to the market would not be felt overnight, potentially taking multiple rate cuts for a meaningful impact. Plus, it’s worth noting that the amount of capital in money market funds as a percent of U.S. market cap has remained rangebound over the same time, also serving as a reminder that the unprecedented acceleration in market cap powered by a handful of index heavyweights, presents concentration risks that should not be ignored.
For example, NVIDIA’s (NASDAQ:) market cap is now larger than the entire listed stock exchanges of all nations outside of the U.S., China, Japan, and India.
Conclusion
The bull market likely has more left in the tank, and there is a notable amount of capital available to be put to work when the Fed resumes its rate-cutting cycle, potentially acting as dry power for U.S. investors. Volatility will come at some point, as macro headwinds such as sticky inflation (with more tariffs on the way) should not be ignored and potential geopolitical shocks remain on the table.
Nonetheless, we expect the path of least resistance for U.S. equities to be higher over the longer-term (with intermittent volatility), supported by Fed rate cuts, moderate but steady economic growth poised to pick up next year, stable long-term interest rates as inflation normalizes, and the powerful ongoing AI capital investment cycle.
