US Treasury Sells $139BN In Two Polar Opposite Auctions: A Stellar 2Y And A Dismal 5Y

Ahead of Wednesday's FOMC decision (where according to SOFR futures, the odds of a rate hike are a significant 38%, even as most traders expect no action by the Fed), we had the week's first two coupon auctions take place according to an abbreviated schedule, with the sale of $69BN in 2Y notes taking place at 11:30am, followed by $70BN in 5Y notes. And while the former was unexpectedly strong, the latter was one of the ugliest 5Y auctions in years.Here are the details.The 2Y auction priced at a high yield of 4.315%, up from 4.189%, and the highest since December 2024. More importantly, it stopped through the 4.320% When Issued by 0.5bps, the third stop through in a row, and the highest since January. The bid to cover was solid, at 2.662, it was also the highest since January. The internals were likewise solid, with Indirects taking down 56.6%, up from 55.5%, if below the recent average of 58.2%. And with Directs awarded 34.1%, roughly flat with 34.3% last month, Dealers were left with just 9.4% of the auction, the lowest since January. But if the 2Y auction was strong - and thus an indication that at least the primary bond buyers don't expect any imminent rate hikes - the 5Y auction was a dismal mirror image.The bond priced at a high yield of 4.408%, a big jump from 4.20% in June and the highest since December '24. It also tailed the When Issued 4.399% by 0.9bps, which made it an unprecedented 14th tailing auction in a row, and the biggest tail since March.The bid to cover was worse: it dropped to 2.282, the lowest in almost 5 years, since Sept 22. The internals were just as ugly, with foreign demand sliding to just 59.24%, the lowest Indirects award since July 2025. And with Directs awarded 27.22%, the most since January, Dealers were left holding 13.5%, the highest since March.In short, today's two auctions - which took place within 90 minutes of each other - couldn't be more different. The impressive 2Y showed remarkable buyside demand, while the dismal 5Y auction, separated by just 3 years in maturity, was one of the ugliest auctions for the tenor in years. Whether it is because someone expects inflation to spike aggressively 3-5 years from today (but not in under 2 years), or just jitters ahead of the Fed, remains to be seen, and when we get next week's 3Y auction, we will have a much better sense of what drove the striking divergence in today's two auctions.
