Stellar 30Y Auction Has First Stop Through Since June, Sparks Algo Buying Frenzy

One month after an abysmal 30Y auction, and after 5 months of tailing 30Y sales, the mood was predictably downbeat ahead of today's 30Y reopening of 29Y-11M cusip TV0, even though the concession was very generous thanks to the move wider in yields and which is why - contrary to conventional wisdom (captured in the always wrong MLIV auction preview) - we said that we would get a stop through today.

Time for a stop through: heading into today's auction the 30Y has tailed each of the last 5 months.

Well, the consensus was wrong as usual and we were right because for the first time since June, the 30Y auction actually did stop through, pricing at 4.344%, 0.3bps through the When Issued 4.347%, and far below last month's 4.769% (which was a 5.3bps tail); this was also the lowest high yield since August and a far cry from the auction cycle high of 4.837% hit in early October.

The bid to cover was also strong, printing at 2.429, the highest since September and above the six-auction average of 2.403%.

The internals were especially solid, with Indirects, or foreign buyers, awarded 68.5%, for above last month's 60.1%, and also well above the six-auction average of 66.6%; in fact it was the highest Indirects since July. And with Directs awarded 14.2%, the lowest since August 2020, Dealers were left holding 17.3%, also well below last month's 24.7%.

Overall, this was a stellar 30Y auction, and the solid reception clearly surprised people who were expecting another disaster; that's why the reaction in the second market sent the yield sharply lower...

... and also sparked an algo buying frenzy with the NYSE TICK indicator surging to HOD of 1310.
