Treasury's Second Buyback in Two Weeks Fails to Stop Bond Selloff

The 10-year Treasury yield closed at 5.163% on Thursday, its highest level since July 2007, according to Dow Jones Market Data. The milestone came on the same day the U.S. Treasury Department ran its second buyback operation this month in an attempt to support liquidity in the government bond market.

The selloff did not spare the long end. The 30-year Treasury yield climbed 5.9 basis points to 5.460%, its highest level in more than 22 years. The 10-year note yield rose 5 basis points, equal to 0.05 percentage point. Bond prices and yields move in opposite directions, so the rise in yields reflects a continued, relentless exit from government debt.

The Treasury's intervention was the second in just two weeks. As MarketWatch's Isabel Wang put it in her Sept. 24 report, "You can't bail out the ocean just by using a bigger bucket. The Treasury Department tried anyway — for the second time in just two weeks."

The buyback program, run under Treasury Secretary Scott Bessent, is designed to repurchase outstanding government notes and bonds to improve market functioning. Back-to-back weak auctions for Treasury notes, however, show that the repurchases have not spurred meaningful demand for bonds, according to the MarketWatch account of the selloff. Investors continue to demand higher yields to hold U.S. government debt, and the department's liquidity operations have so far done little to change that calculus.

The scale of the move is difficult to overstate. A 10-year yield above 5.16% marks territory last seen in the summer of 2007, months before the onset of the global financial crisis. The 30-year yield above 5.46% sits at levels untouched since the early 2000s. Both readings signal that the repricing in the world's deepest bond market has now extended across the entire maturity curve.

The market backdrop on the day underscored the pressure. On the same trading session, the Dow Jones Industrial Average slipped 0.31% to 51,349.98, while the S&P 500 was essentially flat at 7,704.13, down 0.02%, and the Nasdaq Composite edged up 0.01% to 26,939.37. The CBOE Volatility Index, or VIX, rose 3.23% to 15.67. Crude oil gained 2.82% to $94.76 a barrel, and gold slipped 0.19% to $4,310.10.

The data points frame the core problem for Bessent and the Treasury: buyback operations can smooth trading conditions, but they cannot manufacture buyer demand at yields investors consider too low for the risk. Two operations in a single month have coincided with yields pressing to multi-decade highs rather than retreating.

For corporate treasurers, mortgage borrowers and equity investors, the stakes are straightforward. The 10-year Treasury yield anchors borrowing costs across the economy, from corporate debt issuance to home loans. A sustained move above 5% on the benchmark note would raise funding costs economy-wide, and Thursday's close suggests the market has not yet found a level that draws buyers back in volume.

Unless demand strengthens at upcoming auctions, the Treasury faces a narrowing set of options: accept higher borrowing costs, accelerate the buyback program, or adjust issuance patterns. Thursday's action showed investors are not yet buying what the department is selling — in either sense of the word.
