Paying for the buybacks out of the cash tin
If the government's own liquidity buffer becomes a market-management instrument, the shock absorber and the shock are drawn from the same pot.
Two senior Treasury officials told CNBC the department could draw down its cash pile — the Treasury General Account, $935bn as of 20 August — to fund the expanded buybacks of long-dated debt that Scott Bessent announced last week. Ten-year yields fell as much as four basis points to 4.69% on the report (Bloomberg). Dealers had assumed the buybacks would be funded by selling more bills. That version is a swap: retire long debt, issue short debt, no change in the total. Funding it from the TGA is not a swap. The TGA is cash held at the Federal Reserve. When the Treasury spends it, that money moves out of an account at the Fed and into the banking system as reserves. Buying long bonds with it therefore does two things at once — takes duration out of private hands and adds reserves. That is, mechanically, what quantitative easing does, executed by the fiscal authority rather than the monetary one. That comparison is our inference, not the officials'. What has to stay true for it to be harmless: that the Treasury can rebuild the buffer through ordinary auctions whenever it wants. The buffer exists precisely because that assumption occasionally fails. Since 2015 the department's own policy has been to hold at least five days of expenditure, minimum $150bn, in case it is locked out of debt markets. The officials would not say how much of the $935bn might be used, and nothing has been decided. A cash reserve held against the possibility of a failed auction is being considered as a tool for improving the price at auctions. Those are not the same job.
