The third-quarter estimate assumes an end-Sept. cash balance of $750 billion, the Treasury said in a statement.

The Treasury has been cutting issuance since February, when it slashed its borrowing projections for the first and second quarters as part of a plan to reduce its cash balance.

The Treasury said it issued $319 billion in net debt in the second quarter, ending the three-month period with a cash balance of $852 billion.

It expects to borrow $703 billion in the Oct. to Dec. quarter, assuming an end-of-December cash balance of $800 billion.
