US Treasury shifts language, opening door to auction size changes

By · Published by Everything Blog

In short

The department intends to keep coupon and floating-rate note sizes unchanged for the next several quarters, which market analysts interpret as roughly two quarters. While softer demand could make 20- and 30-year bonds prime candidates for eventual size reductions, curbing issuance remains difficult because total outstanding Treasury debt surged to $33 trillion. Immediate liquidity support will include debt buybacks totaling up to $70 billion across the curve alongside adjustments to short-term bill auctions around year-end.

The 20- and 30-year auctions, which have at times struggled to attract demand, are seen as the most likely to be cut. Coupon increases would probably be concentrated in the 2- to 7-year sector, and possibly in 10-year notes.

Speculation about future auction size cuts was sparked in August when Treasury said that it continued to evaluate potential future changes to its coupon and floating-rate auction sizes. That was a change from its May refunding announcement, which had pointed to possible increases.

Not everyone expects cuts to longer-dated debt, though, and Treasury may struggle to reduce auction sizes if its funding needs grow faster…
