The Treasury Department on Wednesday said it will more than double the size of its government debt repurchases, sending yields sharply lower.

With fixed income markets under pressure and yields surging to levels not seen in nearly 20 years, the announcement targets a sensitive part of the Treasury market.

Under the accelerated buyback, Treasury will target the 10- to 20- year and 20- to 30-year portion of the market, which has seen a buyers’ strike since late June. The government will “at least double” the maximum size of its buyback operations, from $2 billion to “at least” $4 billion, according to an announcement from the department.

Honeywell Aerospace is looking very cheap, so it’s a good time to scoop up its shares, according to Morgan Stanley. 

The investment bank upgraded the aerospace name to overweight from equal weight. It has a price target of $205 on shares, implying nearly 28% upside from Tuesday’s close. 

“Our fundamental concerns have not disappeared: HONA screens toward the lower end of peers on revenue and EBIT growth, margin expansion is limited, [free cash flow] conversion trails peers, and lower next-generation Commercial [original equipment] content could constrain the long-term aftermarket opportunity,” analyst Kristine Liwag said in a note to clients. “We believe the valuation now  more than compensates for these risks. HONA warrants a discount to peers, in our view – but not the ~35% discount reflected today.”

Shares of Honeywell Aerospace have fallen roughly 24% in the past month. The company was spun out from Honeywell in late June, as supply chain issues have stymied its operations.

Treasury yields are continuing to climb, and at a particularly bad time as higher rates worsen the impact of the nearly $40 trillion government debt load.

Longer-dated debt has been hit particularly hard by the recent leg up, pushing the 30-year bond yield close to its highest level since the early part of the 21st century. Other maturities also have risen, owing to a number of factors conspiring to raise financing costs.

Fixed income strategists ascribe the run that began in June to a number of variables: intensified concerns over a budget deficit that appears set to eclipse its 2025 level; inflation in an ominous holding pattern above the Federal Reserve’s 2% target despite moderating data over the past two months; and a rash of corporate debt issuance competing with Treasurys for investors’ favor.

Broadly, the move can also be attributed to a rising term premium, or the extra yield investors demand to hold U.S. debt.
