Today’s Lead-Lag Report is brought to you by our friends at Alexis Investment Partners — the father-daughter RIA and ETF issuer behind the Practical Tactical framework and the NASDAQ-listed Alexis Practical Tactical ETF (LEXI).

High valuations and an aging secular bull market threaten to re-assert sequence of returns risks that can ravage retirement income plans. Practical Tactical was built for this — a multi-asset, model informed framework managed by Jason Browne and Alexis Browne Roberts, seeking to add value through market cycles by:

- Participating more in up than down markets
- Pursuing leading sectors and regions and minimizing exposure to laggards
- Incorporating a broader range of asset classes and strategies than traditional balanced portfolios

That framework is wrapped in an ETF — a tax efficient tactical allocation sleeve advisors can use to complement strategic portfolios.

# The Eight Trillion Dollar Myth

### *Money market funds hold a record $8.44 trillion. Wall Street's oldest bull argument says that cash is waiting to pile into stocks. The plumbing of the bill market says otherwise.*

**MICHAEL A. GAYED, CFA**

## Key Highlights

- Total money market fund assets reached $8.44 trillion in Q2 2026, up from $4.73 trillion in January 2020 and nearly $1 trillion higher than a year ago.
- The pile grew straight through the rally: fund assets are up 48% since the start of 2023 while the S&P 500 nearly doubled over the same period.
- The Fed's overnight reverse repo facility drained from $2.55 trillion at its December 2022 peak to under $1 billion, and total fund assets never flinched. That is plumbing, not a queue.
- The 3-month Treasury bill still yields 4.24% against a 3.75% to 4.00% fed funds range: cash is not idle, it is paid.

Every selloff since 2023 has produced the same argument from the same people. There is eight trillion dollars sitting in money market funds, the reasoning goes, and eventually that cash has to come off the sidelines and into stocks, so every dip is being front-run by a wall of dry powder. The number is real. The interpretation is wrong. The $8.44 trillion sitting in money market funds is not a crowd of investors waiting for an invitation. Most of it never intended to buy stocks in the first place, and the proof is that it had every opportunity to leave and grew instead.

Start with who actually owns it. The money market complex is dominated by institutional government funds: corporate treasury departments parking operating cash, securities lenders posting collateral, bond desks parking settlement balances between coupon dates. The retail holder who opened a money market fund in 2023 because her bank paid 0.3% is a real constituency, but she is the minority of the pile. Most of the $8.44 trillion is the working capital of the financial system itself. It needs to be liquid tomorrow morning, it sizes itself against bills outstanding and repo rates, and it does not chase rallies. The Fed's Z.1 Financial Accounts put the total at $8.44 trillion in the second quarter of 2026, and the Investment Company Institute's weekly count stood at $7.94 trillion for the week ended September 23, off repeated records earlier in the month.

The cleanest evidence that this cash is plumbing rather than patience came from the reverse repo facility. At the end of 2022, $2.55 trillion sat in the Fed's overnight reverse repo program, the overflow valve for cash with nowhere else to go. Then Treasury bill supply exploded, and money funds rotated that cash out of reverse repo and into bills, week after week, for three straight years. By late September 2026 the facility held under $1 billion. It was drained to effectively zero, the single largest cash migration of the cycle, and total money fund assets did not fall. They made new records along the way. If this were sideline money waiting for the right moment, the moment to move was somewhere during that drain. It stayed because it was never waiting for anything. It changed where it sat, not what it was.

The growth-through-the-rally point deserves emphasis because it kills the argument on its own terms. Since the start of 2023, the S&P 500 has roughly doubled. A cash pile that was a pent-up bid on equities should have shrunk as the market rose, or at least stagnated as discipline failed. Instead money fund assets rose 48% over the same window. The pile grew alongside the rally, through every record high, through every Fed meeting, through every headline that was supposed to finally pull cash off the sidelines. Two things can both be true: investors were fully willing to own stocks at higher and higher prices, and the money market complex kept expanding, because its growth drivers, bill supply and short rates near 4%, had nothing to do with equity appetite.

The reason it pays to stay is not mysterious. The 3-month bill yields 4.24%, above the midpoint of the fed funds range, and the one-year yields 4.50%. A treasury department or a securities desk holding short cash is being paid handsomely to do nothing dramatic. This is the same point I made last weekend in a different dress: there is an alternative again, and the existence of a paid alternative is precisely what makes record cash a stable fact rather than coiled energy. Cash leaves when the yield leaves, not when the narrative does.

So what would actually move the pile? Not FOMO. Yield. If the front end repriced down toward 3% and below, the marginal institutional dollar would start extending duration, first into short Treasuries and investment-grade paper, not equities. Even then the rotation would be slow and portfolio-driven. The honest counterpoint deserves its space: $8.44 trillion is so large that a 10% reallocation is more than $800 billion, and if even a fraction of that ever reached risk assets it would matter. But the trigger is the level of short rates, which the Fed controls, and the Fed just hiked in September. Record cash with a 4%-plus yield attached is a fact of the rate regime, not fuel with a fuse.

The implication for positioning is humility about one of the most repeated phrases in financial commentary. Cash on the sidelines is not a floor under equities, because it is not a bid at all, it is the balance sheet of the short end. Watch bill yields and the repo complex if you want to know when the pile might shrink, and notice that the record was set while the S&P 500 doubled, not before it. Few understand this.
