Mischler Cash Commentary

Money Market & Front-End Liquidity Update

Record Money Market Fund AUM reached last week (Friday saw outflows into Tax Day). Tax Day and Fed Day this week, with hikes locked in and the full focus of the market. Record cash is not as impressive a sideline vs market cap. Technology cash at a record. The FOMC may need a Ouija board for this meeting: "Hello, Greenspan."

USD money funds reached a record $9.33 trillion as deal cash fuels Technology cash to a record $1 trillion. Corporate tax receipts have been running light YTD and tariff refunds higher, just as Treasury buybacks start and rising defense spending keep bill supply higher than the market expects. Warsh may weigh 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. 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 as Repo volumes remained well below average; Prime cash is feeding a record $939 billion in Yankee CDs and ABCP nearing a $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 corporate profits as accelerated depreciation drives the gap wider. The September 15 corporate tax date, coupon settlement and the FOMC (September 15 and 16) all land 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 of Fed purchases, supply will be $6.9 trillion, while foreign official accounts (Japan) have been net sellers, leaving Money Funds and the Fed as the marginal buyer. The biggest "risk" is that Repo leverage returns as Bill Supply grows. Still, the plumber is on call, and the Fed will ramp RMPs with Treasury repo and the 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.

Section I

Front-End Liquidity Dashboard

We hit a new record, just in time for Corporate Tax Day outflows. Record profits should pull about $45-50 billion, although it should be larger; corporations are holding on to more of those profits

Money Fund Assets: Where the Cash Is Going

01

Record $9.33 Trillion, Offshore Leads

Record $9.33 Trillion, Offshore Leads

Total domestic and offshore USD money funds climbed back to a record $9.33 trillion, driven by a record $928 billion in USD offshore funds. The domestic money market fund total is just shy of its July 6 record, as we head into September Tax payments.

02

Treasury Funds at a Record $2.70 Trillion

Treasury Funds at a Record $2.70 Trillion

Treasury-only funds keep grinding higher to $2.70 trillion combined. Bill supply's marginal buyer, with cash that needs to be put to work.

03

Treasury Institutional: $2.23 Trillion

Treasury Institutional: $2.23 Trillion

Institutional Treasury funds set a new high at $2.23 trillion, up roughly $480 billion since late 2024. Large Technology treasurers need to park their $1 trillion pile, and tariff refunds continue to support inflows.

04

Prime Total: $2.07 Trillion Record

Prime Total: $2.07 Trillion Record

Combined domestic and offshore Prime assets broke through a record $2.07 trillion, steadily climbing back from reform outflows.

05

Prime Institutional Crosses $1.07 Trillion

Prime Institutional Crosses $1.07 Trillion

Prime institutional assets hit a record $1.07 trillion, up about $230 billion since late 2024. Prime growth is what funds the CD, Yankee and ABCP records further down.

06

Government Total: Flat Since June

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.

07

Government Institutional: Below the February Peak

Government Institutional: Below the February Peak

Government institutional funds have been the laggard after peaking at $2.90 trillion in February and have traded sideways near $2.82 trillion since. The growth has rotated to Treasury-only and Prime.

08

Cash Is Not as Deep a Bench as the Headlines Suggest

Cash Is Not as Deep a Bench as the Headlines Suggest

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

11

Bill Supply Heading Toward $7.5 Trillion

Bill Supply Heading Toward $7.5 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.

12

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.

13

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.

14

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 we may be near the max, with maybe another $10 billion left.

15

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. It has also helped contain some inflation pressure, for now (i.e., Walmart holding prices unchanged, but still making bank!)

Taxes & Receipts

16

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.

17

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.

18

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

19

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.

20

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 was trimmed over the summer holiday; does the fall push us higher?

21

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 the basis trade and levered money for repo's turn.

22

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.

23

Total TriParty

Total TriParty

Total tri-party: Treasury and Agency MBS repo supply is moving lower as Government fund assets remain below highs, easily replaced by non-traditional supply.

24

Equity TriParty

Equity TriParty

Non-Traditional Equity Supply reaches a new high. No surprise given the leverage in equities.

25

Treasury and Agency TriParty

Treasury and Agency TriParty

Treasury and Agency MBS Repo supply moving lower.

26

Corporate TriParty

Corporate TriParty

Corporate non-traditional tri-party collateral supply higher.

Equity Financing & Leverage

27

Equity Financing Holds Near $470 Billion

Equity Financing Holds Near $470 Billion

Equity financing is $472 billion, off the $515 billion high of July 3 but well above the $345 billion low last October.

28

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.

29

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.

30

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 run up the tab into year-end?

31

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.

32

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

33

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.

34

Yankee CDs: Record $939 Billion

Yankee CDs: Record $939 Billion

Yankee CD outstandings reached a record $939 billion on September 2, up $122 billion from the November low. Foreign banks are funding in dollars with Prime fund cash.

35

CP & CD Outstandings: $2.36 Trillion

CP & CD Outstandings: $2.36 Trillion

Combined CP and CD outstandings are $2.36 trillion, just off the August 28 high of $2.37 trillion and up $215 billion from last November's low.

36

Credit's Share of Fund Assets Stays Low

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

37

Agency Outstandings: $2.12 Trillion

Agency Outstandings: $2.12 Trillion

Total agency debt eased to $2.12 trillion in August from a $2.17 trillion peak in June, still up about $150 billion year-to-date.

38

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.

39

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 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 12% Ahead

Interest Payments Running About 12% Ahead

Interest paid year-to-date is $1.3 trillion (+$140 billion), running roughly 12% ahead of the same point in 2025 ($1.159 trillion).

Section III

AI Capex & Corporate Cash

The Hyperscaler Balance Sheet

01

Hyperscaler Debt Has More Than Doubled

Hyperscaler Debt Has More Than Doubled

Long-term debt at the six largest AI builders (Alphabet, Microsoft, Oracle, Amazon, Meta, SpaceX) has more than doubled in three quarters, from about $215 billion to $500 billion.

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 Centers Driving Fed Policy

Data Centers 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 Kashkari are significantly impacted and may be driving their views on inflation and the economy. Goolsbee is concerned about inflation but hasn't been as vocal, while Atlanta has an interim president and is quiet. The eastern corridor has historically been active, so it wouldn't have the same relative impact on the economy. U.S. data center clusters: 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 a Ouija board for the Sept meeting and have Greenspan join. Greenspan made a very similar decision in 1999 when he raised rates (although without the 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 expected at 3.49% (up from 3.34%), roughly 175 basis points above where it ran in 1994-95, cutting rates in 1995-1996 by 75bps.

02

June 1999: The Template

June 1999: The Template

1998 LTCM cuts mirror Powell's (policy error) cuts of 2025. Greenspan reversed them in 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 with 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. The "House" wins and Trump is 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 to market cap, and a Fed channeling 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 makes 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 real-time 1.3% "Tru"flation and Walmart are the real indicators, or whether the lagging 3.49% is the inflation 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 Bessent, a Fed hike (+50bps) and a hawkish Fed drive the long end lower and force short-covering and a sustained rally? Leverage returning to Treasuries and the Repo market?
