US Treasury Reportedly Weighs Its 950 Billion Dollar Cash Account to Fund Expanded Bond Buybacks
The US Treasury is considering drawing on the cash in its Treasury General Account, which stood near 950 billion dollars in mid-August, to help fund its expanded purchases of longer-dated government bonds, CNBC reported on Monday, citing two senior Treasury officials. Treasury has not announced such a funding change.
The distinction matters because the buyback expansion itself is already official, and was covered in our 21 August report. Treasury said on 19 August that the maximum size of its liquidity-support buybacks in the 10-to-20-year and 20-to-30-year sectors would rise from 2 billion dollars to at least 4 billion dollars per operation, effective 9 September and running through 4 November. What is new is the reported possibility of drawing on the government’s cash balance as an additional funding source alongside the short-term bill issuance markets had expected. The officials did not say how much, if any, of the account might be used or when such a change could be announced.
| Indicator | Figure |
|---|---|
| Buyback maximum, long-end operations | From 2bn to at least 4bn dollars |
| In effect | 9 September to 4 November 2026 |
| Treasury General Account, 19 August | 936.4bn dollars |
| Treasury General Account, weekly average | 953.6bn dollars |
| Total US public debt | Above 40tn dollars |
Federal Reserve data show the Treasury General Account, the government’s operating cash account at the central bank, held 936.4 billion dollars on 19 August, with a weekly average of 953.6 billion dollars. That is well above the roughly 550 billion to 600 billion dollar range targeted under the previous administration, a build-up CNBC attributes to Treasury Secretary Scott Bessent. A single enlarged 4 billion dollar operation is equivalent to only about 0.4 percent of the account’s 953.6 billion dollar weekly-average balance, our calculation, which illustrates the scale of the cash account relative to individual operations without implying that the full balance is available for buybacks. Any cash used would still leave a smaller cushion against a future debt-ceiling episode and would have to be replenished through taxes or issuance.
The reported idea follows a sharp rise in long-term borrowing costs, with the 30-year Treasury yield reaching its highest level since 2007 in mid-August, and comes as total US public debt has passed 40 trillion dollars. Using existing cash rather than new bill issuance would change the timing and composition of Treasury’s cash and issuance flows around the operations, but would not reduce the government’s underlying financing need and would not be equivalent to Federal Reserve asset purchases.
Why it matters: Funding buybacks from cash rather than fresh issuance would change how much new short-term supply the market must absorb while Treasury supports the long end, and the reported availability of the cash account gives Treasury a potentially larger funding source than markets had assumed, which could shift perceptions of the program’s capacity after its initial expansion produced only a brief move in yields. How much of that capacity Treasury would actually use is unknown, and because the plan is reported rather than announced, it remains subject to official confirmation.
Outlook: The markers are whether Treasury formally addresses use of the cash account, the take-up at the first enlarged operations in mid-to-late September, and the next quarterly refunding statement on 4 November, which would clarify the scale and duration of the support.
