1 min read Data: Refunding $103bn, first rise since 2021

The sovereign borrowing machine is accelerating, and the private sector is about to feel the draft. When the US Treasury announced its quarterly refunding schedule on 2 August, raising the auction size to $103 billion—the first increase in coupon issuance since 2021—it confirmed that the era of benign duration supply is over. To finance ballooning deficits, Washington must flood the long end of the curve with fresh paper.

Crowding Out the Private Ledger

This avalanche of sovereign duration arrives precisely as corporate treasurers are preparing to refinance vast tranches of post-pandemic debt. With benchmark Treasury yields resetting higher to absorb the new supply, investment-grade corporate borrowing spreads must widen or base rates must climb. The sovereign borrower does not price out of need; it dictates the clearing rate, leaving corporate issuers to absorb the escalating cost of capital.

The Treasury’s expanded refunding schedule marks the return of sovereign crowding-out, where the insatiable financing appetite of the state bids up capital costs for every private enterprise.
