Bessent asked for $6 billion. The Treasury got $5.2 billion, and the 30-year still went to 5.36%, the highest since 2007.
The Buyback Failed, and the Long End Kept Rising Everywhere
That was September 10. The buyback had tripled the day before. Yields rose on the announcement and on the undershoot.
The US 10-year was at 4.96%, its highest since November 2023. Japan's 10-year touched 3.005% on September 1, the first time since 1996. The UK's 30-year gilt syndication printed at 5.8168%, the highest since 1998, with cash pushing to roughly 5.93%.
Germany 3.50% (April 2011). France 4.44%, spread over Germany ~93bp, widest since 2012. Australia 5.37% (mid-2011). Japan 30-year above 4.00%.
In 2022 inflation spiked globally, but Japan was pinned at zero. This time Japan is in the move.
Four Forces
Oil is back above $100 after the Iran conflict flared. Every economy that imports energy feels it, and every central bank hoping inflation was transitory has to recalibrate.
Governments are issuing more debt at the same time. The US crossed $40 trillion in mid-August. Healey's October Budget hangs over UK gilts. Japan's budget is at record size. Germany's full-year plan includes €82 billion in Bunds.
Central banks are being repriced toward tighter policy. The ECB raised 25 basis points to 2.50% on September 10. The RBA is pricing roughly a 72% chance of a fourth hike by September 29. In Japan, BOJ board member Hajime Takata called for nimble rate hikes on September 2, and Governor Kazuo Ueda confirmed hikes are on the table at every meeting, including September 17-18. A year ago the consensus was cuts into 2026. That trade is dead.
Corporate borrowing is crowding out the long end too. The five largest AI hyperscalers issued roughly $220 billion in bonds over the past year, according to Reuters. Some desks are flagging that AI-related long-duration issuance is eating a growing fraction of new long Treasury duration. That is a supply shock on top of the sovereign supply shock.
The One Government That Scaled the Intervention Still Lost the Tape
The US Treasury buyback was designed to support the long end by tightening supply. It got bigger, and yields still went up. The UK does not have a comparable buyback tool. Neither does Japan. Neither does Germany.
Most of the nominal yield rise is real. Ten-year TIPS (constant maturity) were at 2.55% on September 10. The 30-year TIPS on the 2046 line was about 3.03%. The 10-year Treasury breakeven inflation rate was roughly 2.40%. ING reads real yields as the central driver, with breakeven inflation contributing on the margin. Warsh at the Fed has stripped away forward guidance entirely. Markets hate a central bank that refuses to pre-commit. That uncertainty gets priced into the long end.
The move is not isolated to the long end. Two-year yields jumped from roughly 4.43% to 4.56-4.59% on September 10. Five-year yields pushed to around 4.75-4.77%. Hike odds moved alongside term premium.
The France-Germany spread blew out to roughly 93 basis points as of September 11, the widest since 2012. Burnham's government in the UK is the same story in a different currency.
Japanese life insurers, UK pension funds running LDI strategies, European banks' bond books, and official accounts are the usual buyers of long-duration paper. They are either full, marked at a loss from earlier purchases, or being asked to absorb both sovereign and hyperscaler issuance at the same time. When the forced holders are already full, the price has to clear higher to find marginal buyers.
The yen is firm near 153 against the dollar, close to a seven-month high, because the BOJ hike is almost fully priced. Sterling was roughly unchanged near $1.355. The dollar index faded.
Duration-sensitive assets are already under pressure as real rates climb.
As of September 10, the 30-year TIPS on the 2046 line was 3.03%.
