The Fed's plumbing

Communicating vessels

The Treasury's account and the reverse repo: what fills them, what empties them, who decides, and why the same bond issuance can drain reserves one year and not the next.

The TGA: the government's checking account

Predict which way the TGA moves with taxes, spending, debt issuance and the debt ceiling.

The Treasury General Account (TGA) is where the US government keeps its cash, at the Fed. When you pay taxes or an investor buys a Treasury bill, money goes from a bank account to the TGA: it leaves the banking system. When the government pays salaries, pensions or contractors, it comes back.

  • ▸Tax dates (mid-April, and the quarterly payments of June, September and December): the TGA rises.
  • ▸Settlement of large bond auctions (often mid-month and month-end): the TGA rises.
  • ▸Big payment days (Social Security, interest): the TGA falls.

The debt ceiling

When the government hits its legal debt limit it cannot issue new debt, so it spends from the TGA, which empties — injecting money into the banks. In 2023 the TGA fell below $50 billion before Congress raised the limit in early June. Then the Treasury refilled it by issuing hundreds of billions in bills within a few months: the reverse — a drain.

Key idea
The TGA is the box that moves fastest. A single tax day can move it more than a month of QT.
Tip
The Treasury publishes the TGA balance every business day in the Daily Treasury Statement, with the previous day's figure.
