Treasury pays 5.42% for twenty-year money as the indirect bid hits a six-year low

Price the extra yield and it is not much money. The 21.6 basis points Treasury paid over the August 19 auction, applied to $13 billion, is about $28 million a year of coupon, roughly $561 million across the twenty years ^[1][2]. The 2.0 basis point tail against the when-issued bond costs about $2.6 million a year ^[3]. One tranche this size is too small to move the federal interest bill, so what matters is who bid.

Indirect bidders took 52.5% of the sale, $6.78 billion, the lowest share in the six years the modern 20-year auction has existed ^[9]. That leaves $6.22 billion for primary dealers and direct bidders ^[6]. Indirect bidders are the ones who place a competitive bid through a primary dealer or a direct submitter, a group that includes foreign central banks bidding through the New York Fed ^[10]. Wolf Richter, who reported the auction for Wolf Street, wrote: "While the auction results lump foreign bidders together with other indirect bidders, the low ratio suggest that there was severely lacking enthusiasm among foreign buyers for the 20-year bond" ^[11].

The case for a repriced long end rests on the level everywhere else: the 20-year at 5.41% in the secondary market after touching 5.44% in the morning, the 30-year at 5.37% and the 10-year at 5.0%, each the highest since 2007 ^[12][13]. Richter puts 2007 as the last year before the Fed's QE and interest rate repression, and writes that 5%-plus yields were considered normal to low in the decades before it ^[16].

Some of the 20-year's own record is mechanical. The maturity generally clears above the 30-year, by as much as 20 basis points in 2020 and a few basis points lately, because the float is small, the auctions are small, liquidity is low, and it features high on the Treasury buyback list ^[14].

The October 2023 precedent cuts against reading this print as permanent. That auction cleared at 5.245%, the record until today, and the 20-year yield then fell about 130 basis points in the secondary market over the following 11 months ^[4][5]. Today's yield is 17.5 basis points above that old record ^[5].

In my view the indirect share is the more informative of the two figures. A clearing yield can be produced by one thin afternoon; a six-year low in indirect participation has to be produced by a change in who wants twenty-year duration ^[9]. If the next auction lifts that share and the 20-year retraces the way it did after October 2023, this was a supply-and-liquidity print in the thinnest maturity on the curve ^[5][14]. Anyone resetting a twenty-year hurdle rate off 5.42% is moving a base rate that has already travelled 25.7 basis points since July's 5.163% auction ^[3][4].

"The function of yield is to create demand. And it did," Richter wrote ^[15].
