Treasury's 10- and 30-year auctions clear at yields last seen in 2000

Treasury sold $121 billion of 3-, 10- and 30-year debt this week at the highest auction yields in over 20 years, including 5.30% on the 10-year. Buyers took all of it and the 10-year eased to 5.24% by Friday, so the week sets a clearing level for long debt that the next auctions will test.

What happened

  • Thursday's 30-year bond auction sold $23 billion at 5.618%, the highest 30-year auction yield since August 2000.
  • The 3-year note auction on Tuesday cleared at 4.932%, the highest since May 2006 and up from 4.474% at the previous auction a month earlier.
  • Bills made up most of the week's $728 billion: $607 billion of 4- to 26-week paper across six auctions, four of them above $100 billion, mostly replacing maturing bills.
  • Wednesday's $39 billion 10-year sale came in better than when-issued trading had expected, and the market calmed afterward.

Why it matters

  • cost The 3-year's 46 basis point rise in a month adds roughly $270 million a year of interest on this one $59 billion sale, for each of its three years.
  • exposure Holders who bought 10-year notes before late February are carrying price losses from a 125 basis point rise in yield, and this week's buyers take the same hit if later auctions need higher yields.
  • exposure With about 83% of the week's issuance in bills maturing within 26 weeks, most of this new borrowing reprices within half a year, so its cost tracks whatever hikes the 3-year is pricing.

Take the $39 billion 10-year and the $23 billion 30-year out of the $121 billion of coupon sales and what remains is a $59 billion 3-year [4][8][13][21]. At the three auction yields, that paper carries about $6.3 billion of interest a year, a weighted cost near 5.18% [22]. Every bill sold during the week also priced at an investment rate above 4% [3].

How far back each high reaches depends on the maturity. The 10-year's 5.30% was the highest since November 2000 [8]. Even so, it is about 120 basis points below the 6.5% range the 10-year auctioned at in the first half of 2000 [9][24]. The 30-year comparison also spans a gap: there were no 30-year auctions between August 2001 and 2005 [14].

Wolf Richter wrote on Wolf Street that the higher yields were "what it took to sell all $121 billion of these notes and bonds" [4]. Trading after the sales went the other way. The 10-year finished the week 6 basis points under its auction yield [25]. The 3-year had cleared below the just-over-5% it traded at in late September, and it closed the week at 4.92% [6].

Buyers who took the 10-year at 5.3% may keep turning up, in which case this week was the high for the long end. Or deficits of about $2 trillion a year, all financed by new debt that has to find new buyers, could push every sale higher [15]. Richter wrote that this is the market's fear, that "the tsunami of supply of new Treasuries would require still higher yields to rope in new buyers" [17]. A third outcome starts at the short end. The 3-year yield is up 150 basis points since February and already prices several hikes beyond September's [7]. If those hikes do not come, yields have room to fall from the front.

We think the second outcome has the better evidence. Treasury is competing for cash with corporate borrowers paying far more: SpaceX 10-year notes traded at 7.20% on Friday, 196 basis points over the 10-year Treasury's close [16][26]. Richter wrote that inflation "has refused to go back into the bottle" and called it the biggest long-term threat to holders of long Treasuries [18]. The case against us is that both notes drifted lower after their auctions [6][25]. We would be wrong if the next 30-year auction clears below this week's yield while deficits stay near $2 trillion a year [13][15].

What to watch

  • Whether the 10-year trades back above its auction yield in the secondary market before the next 10-year sale.
  • Bill investment rates against the 4% line as the hikes priced into the 3-year either arrive or fall away.
  • Yields on AI-company debt such as SpaceX's 10-year notes, where a narrower gap to Treasuries would ease the competition for buyers.
