US Treasury wording signals possible changes to bond auction sizes

The US Treasury changed its guidance on future bond auctions, suggesting it may adjust how much debt it sells in different maturities.

It expects to keep some auction sizes unchanged for “the next several quarters,” which analysts interpret as about two quarters, leaving changes possible in the first half of 2027.

Analysts expect increases in sales of two- to seven-year debt and possible cuts to 20- and 30-year auctions, which have sometimes struggled to attract buyers.

The shift follows a bond selloff last month that pushed 10- and 30-year Treasury yields to their highest levels since 2002.

Long-term auction cuts are not certain because the government may need more financing than expected, and its debt has grown to $33 trillion from $14 trillion over the past decade.

The Treasury also plans to make seven-year notes a quarterly auction, adjust short-term bill sales seasonally and buy back up to $70 billion in Treasuries to support market liquidity.

Next week, it plans to sell $125 billion in Treasury securities, including three-, 10- and 30-year debt.
