Money Market & Front-End Liquidity Update

Greenspan ouija board time. Record Cash, sidelines are not as impressive vs market cap: Tax Day and Fed Day the Focus.

Money funds are back at $9.33 trillion as deal cash fuels Technology cash towards record $1 trillion. Corporate Tax receipts running light, tariff refunds keep flowing, as Treasury buyback start and defense spending increases will keep Bills supply higher. Warsh weighs a 1999-style move. "To have refrained from doing so in our judgment would have put the U.S. economy's expansion at risk." - Greenspan 1999

Cash is back at a record. Total USD Domestic and Offshore Money Fund assets reached a new record $9.33 trillion this week, led by a record $928 billion offshore, with the domestic total just shy of its July 6 high. Treasury-only and Prime funds are setting records while Government funds sit below their February peak. As Treasury 7-day yields continue to outperform, which may shift with a Fed rate move and higher expectations. Treasury cash was key, feeding the Treasury's Bill appetite s Repo volumes remained well below average; Prime cash is feeding a record $939 billion in Yankee CDs and ABCP near $500 billion tsunami.

This week we have September Tax payments which may pull $50 billion from money market funds, although YTD Corporate Tax receipts are well below the Corporate's profits as accelerated depreciation drive the gap wider. The September 15 corporate tax date, coupon settlement and the FOMC on September 15 and 16 midweek. Corporate receipts are running roughly $120 billion behind FY2025 even with profits at a record, and tariff refunds have now returned $140 billion to corporates this year. Walmart's gross margin jumped 96bps, primarily on those refunds. Treasury fills the gap the only way it can: Bills. Gross bill supply is projected to climb toward $7.5 trillion by year-end (with risk higher) although net supply of Fed purchases will be $6.9 trillion although foreign official accounts have been net sellers - Japan, leaving Money Funds and the Fed as the marginal buyer. Biggest "risk" is Repo leverage returns as Bill Supply grows. Although the plumber is on call and the Fed will ramp RMPs with Treasury Repo TGA looming.

Repo stays quiet for now. SOFR volume is 35% of fund assets, down from 43%, because the leveraged Treasury long has not come back; the leverage went to equities instead, where margin debt is up roughly $500 billion since 2024. Inflation is a split screen: Core PCE at 3.49% against Truflation at 1.28%. Warsh wants real-time data and Walmart's quarterly report says $4 gasoline is the consumer's breaking point. September will show which series Warsh trusts, and whether Greenspan's 1999 playbook is our guide. He failed in July to make his 1994 Greenspan statement.

Government Total: Flat Since June

Total Government fund assets peaked at $4.47 trillion in June and sit near $4.39 trillion. Government funds are the repo buyers; flat assets are one reason repo volume is soft.

08

Cash Is not as deep of a bench as the headlines.

Cash Is not as deep of a bench as the headlines.

Money fund assets are only 10.7% of U.S. equity market cap, well under the 12% long-run line. Record cash, near-record low cash as a share of risk assets, speaks to the leverage in equities.

Bill Supply & Treasury Cash Flows

09

Bill Supply Heading Toward $7.6 Trillion

Bill Supply Heading Toward $7.6 Trillion

Gross bills outstanding are projected to climb toward $7.5 trillion by year-end, with net supply (ex-Fed) near $6.9 trillion, standing by the phone if needed. After a September pause, the ramp resumes in the fourth quarter. Watch Repo volumes.

10

Bills vs Fund Assets: 86% Gross, 78% Net

Bills vs Fund Assets: 86% Gross, 78% Net

Bill supply as a share of money fund assets has climbed back to 86% gross and 78% net. With the Fed buying, it has not reached a critical level, but the cushion is thinner than in the spring.

11

Foreign Official Accounts Step Back

Foreign Official Accounts Step Back

Foreign official accounts have been net sellers of T-bills, roughly $60 billion at the low. Domestic money funds and the Fed are left as the marginal buyers.

12

Tariff Refunds: $140 Billion and Counting

Tariff Refunds: $140 Billion and Counting

Customs refunds have reached $140 billion year-to-date versus about $4 billion in 2025. The late-June step (roughly $36 billion in a week) was the largest single move; flows have slowed but not stopped. although reaching the max, maybe another 10 billion left.

13

Where Tariff Refunds Land: Margins

Where Tariff Refunds Land: Margins

Walmart's gross margin rose 96 basis points to 25.4% in Q2 FY27, primarily driven by tariff refunds. Refund cash lands in corporate treasurers' coffers, then money funds. Although has help contain some inflation pressures, for now (ie Walmart holding prices unchanged, but still making bank!)

Taxes & Receipts

14

Corporate Receipts Running Behind

Corporate Receipts Running Behind

Q2 corporate receipts were $170 billion versus $209 billion a year ago. Q3 is tracking well below 2025 ahead of the September 15 payment date.

15

FY2026: Roughly $120 Billion Light

FY2026: Roughly $120 Billion Light

Cumulative corporate receipts for FY2026 are tracking near $337 billion against $460 billion for all of FY2025. September 15 is the last chance to narrow the gap; bill supply covers what it cannot.

16

Profits Up, Taxes Down

Profits Up, Taxes Down

Corporate profits are running at a record near $4.8 trillion while quarterly tax receipts fall. Bonus depreciation and capex expensing pull the tax bill forward, and Treasury funds the difference in the bill market.

Repo & Dealer Financing

17

SOFR Volume: 35% of Fund Assets

SOFR Volume: 35% of Fund Assets

SOFR volume has slipped to 35% of money fund assets from a 43% peak. Leveraged Treasury longs remain limited, so repo stays soft with fund inflows and Fed bill buying. August was a summer repo snoozer; September brings Fed and Treasury buying against a decline in bill supply.

18

Dealer Financing Off the July Record

Dealer Financing Off the July Record

Total dealer financing is $5.08 trillion, down from the $5.29 trillion record on July 3. Leverage has been trimmed during summer holiday, does the Fall push us higher?

19

Treasury Financing: $3.45 Trillion

Treasury Financing: $3.45 Trillion

Treasury financing has eased to $3.45 trillion from $3.66 trillion in March and is turning higher off the August low. Decline was just in time to offset the Bill supply return. Watch for the basis trade and levered money for repo's turn?

20

FICC & Bills vs Fund Assets

FICC & Bills vs Fund Assets

FICC repo plus bills equals about 99% of money fund assets, while dealer financing has fallen to 55% of fund assets from 58% in the spring. The funds have the balance sheet; dealers are not asking for it.

26

Term Rising, Overnight Fading

Term Rising, Overnight Fading

Term equity financing has climbed to $172 billion while overnight has slipped to $293 billion. Borrowers are locking in term funding, a sign they expect to hold the leverage.

27

Equity Basis vs SOFR-IORB

Equity Basis vs SOFR-IORB

The September equity basis has eased back near 80 from the June spike above 110, while SOFR-IORB holds near zero. Equity funding pressure has not spilled into Treasury repo; it is the spread to watch into quarter-end.

28

Margin Debt vs Equity Financing

Margin Debt vs Equity Financing

Margin debt is up about $500 billion since 2024 to $1.42 trillion. Equity financing fell $38 billion in July to $476 billion, but both remain near their highs. Summer sabbatical as leverage turned lower, do we see a running through the tab into year-end?

29

Leverage as a Share of the Market

Leverage as a Share of the Market

Margin debt and equity financing as a share of market cap are off their June peaks but well above 2024 levels. As prices rise the ratios should fall; they have not.

30

Equity Financing Other vs ABCP

Equity Financing Other vs ABCP

Other Equity financing ($264 billion) and ABCP ($498 billion) have moved in lockstep since last fall. The same non-traditional funding channel is feeding both - Prime Fund inflows have helped as non-traditional Repo and ABCP have increased - demand / supply in balance for now.

Commercial Paper, CDs & Yankees

31

ABCP Near $500 Billion

ABCP Near $500 Billion

Asset-backed CP has grown about $90 billion since November (+22%) to $498 billion, near a 20-year high. Total CP stands at $1.45 trillion. ABCP may be reaching a breaking point. Supply continues as more programs enter the market. Keep a watchful eye on the dealer balance sheets.

Credit's Share of Fund Assets Stays Low

CP and CDs are 28% of money fund assets versus 42% in 2022. Record issuance, yet credit's share of the cash pool is near its lows, leaving room for Prime to absorb more.

Agency Supply

35

Agency Outstandings: $2.12 Trillion

36

Agency Floaters: Record Near $895 Billion

Agency Floaters: Record Near $895 Billion

Agency floaters reached a record near $895 billion, up about $240 billion since January. Floaters remain the preferred tool while fixed-rate demand waits on the Fed.

37

Discount Notes Down $145 Billion From April

Discount Notes Down $145 Billion From April

Discount notes fell to about $448 billion from a $592 billion April peak. Issuers are terming out into floaters; fewer discount notes mean more demand for bills.

Section II

Government Refinancing: The Cost of the Debt

Interest Expense

01

Interest Expense: $1.27 Trillion FYTD

Interest Expense: $1.27 Trillion FYTD

FY2026 interest expense is $1.27 trillion ($1.3 trillion Sept 10th) fiscal year-to-date at a 3.49% average rate (up from 5bp from last month), on pace to top FY2025. The front end sets the funding cost for a third of the debt and the Fed isn't going to help this week.

02

Interest Payments Running About 13% Ahead

Interest Payments Running About 13% Ahead

Interest paid year-to-date $1.3 trillion (+$140 billion), running roughly 13% ahead of the same point in 2025 ($1.159 trillion).

02

Tech Cash Tops $1 Trillion

Tech Cash Tops $1 Trillion

Aggregate cash at the ten largest technology firms has climbed from about $595 billion to over $1 trillion since October. Bond proceeds sit in money funds and bills until capex draws them down.

03

Data Center driving Fed Policy

Data Center driving Fed Policy

If you overlay Data Center growth and therefore demand for labor, energy and services with the regional Federal Reserve Banks, you can see why Hammack, Logan and Kashhari are significantly impacted and may be driving their views on inflation and the economy. Goolsbee is concerned about inflation but has been as vocal while Alanta is an interim and quiet. The eastern corridor has historical been active so wouldn't have the same relative impact on the economy. U.S. data center: Texas, Chicago, the Ohio Valley, Atlanta. Power and grid demand follow the same map. Bottom line: data centers are driving the economy and inflation, and may be a long term driver of energy demand and inflation.

Section IV

Historical Parallel: 1999, Not 1994

Warsh may need ouija board for the Sept meeting and have Greenspan join. Greenspan made a very similar decision in 1999 when Greenspan raised rates (although without inflation hurdle). The full piece, 1999, Not 1994, is on mischlercashcommentary.com.

The Template

01

The Current Cycle vs 1994-95

The Current Cycle vs 1994-95

This cycle started from 3% in 2023, like Greenspan's February 1994 surprise hike from 3%. Fed funds sit at 3.75% with Core PCE at 3.34%, roughly 160 basis points above where it ran in 1994-95, cutting rates in 1995-1196 by 75bps.

02

June 1999: The Template

June 1999: The Template

1998 LTCM cuts mirror Powell's (policy error) cuts of 2025. Greespan reversed the June 1999 - "To have refrained from doing so in our judgment would have put the U.S. economy's expansion at risk." a statement that may sound similar this week. He followed by 175 basis points of tightening into 2000. The Committee hiked and dropped its bias in the same statement, and the curve rallied. We may get a hike and a hawkish statement that drives the long-end lower and helps Bessent as well. Letting the "House" win and Trump ultimately happy.

03

Truflation 1.28% vs Core PCE 3.49%

Truflation 1.28% vs Core PCE 3.49%

Real-time Truflation core has fallen to 1.28% while Core PCE sits at 3.49% up from 3.34%. Warsh wants real-time data. This chart is the argument for waiting; the 1999 chart is the argument for moving.

Bottom Line

Record cash, although not a deep bench relative the market cap, and a Fed channel Greenspan 1999. .

Money funds have the cash and Bessent may want a piece of it, so the plumbing can absorb 4th Quarter supply. Corporate Tax should be off the charts given the record profits, but may be thin as accelerated depreciation make Tech Treasurers smile (for now, will equities learn they are taking from the future?). The pressure point is not treasury leverage and funding and SOFR. It is leverage parked in equities (and ABCP), and a Fed hiking rates. Warsh will have to decide whether a real-time 1.3% "tru"flation and Walmart is a real time indictor or a lagging 3.49% is the inflation is the what he's held to.

Prime has helped Equity leverage (ABCP/Non-Trad Repo) remain contained and Treasury Funds (and the Fed) have helped digest Bill supply. What will the 4th quarter bring? Watch ABCP, Treasury leverage. A Real Treasury rally may be key - Can a Bessent, Fed Hike (+50bps) and Hawkish Fed drive the long-end lower and force a short-covering and sustained rally. Leverage returning to Treasuries and the Repo market?
