Scott Bessent's whole job pitch was simple - get long-term borrowing costs down. The bond market has not been cooperative.
Yields keep climbing, and the Treasury secretary's tool kit is thinner than the title suggests.
Bessent can shape the mix of short-term Treasury bills versus long-term bonds the government sells, and he can lobby Congress for tighter spending. That's basically the list.
What he cannot do is set the Fed's interest rate, move inflation expectations on demand, or stop foreign buyers from rotating out of U.S. bonds when they want to.
Vishal Khanduja at Morgan Stanley Investment Management has called Bessent a "volatility seller," meaning a Treasury secretary who steps in to calm sharp moves in markets like Treasuries, the yen, and Argentina's peso. Calming a yield trend that's been building for months is a different job entirely.

In a Reuters interview from Paris last week, Bessent said high yields and headline inflation are "transient" and will subside once the Iran conflict winds down.
His logic leans on oil markets that already see through the conflict, with Brent crude for July delivery at $105 a barrel but December delivery priced at just $88. Traders are essentially pricing in a resolution by year-end.
If Iran ends sooner, energy prices fall and bond yields likely follow. If it drags on, the "transient" story falls apart.
Rising yields drag on everything - mortgages, corporate debt, and the stock market, since investors can earn more from "risk-free" government bonds. For more on how the Fed and Treasury actually drive the cost of money, see our Fed explainer.
It also limits what the White House can do, because every basis-point move higher costs the government more to service its debt.
The 10-year hit 4.671% last week, the highest since January 2025, while the 30-year touched 5.178%, the highest since June 2007.
A 100 basis-point drop in 10-year yields would save the government roughly $1 trillion in interest costs, a figure Bessent himself has cited.
That's the prize, and hoping Iran wraps up quickly is the plan.
The bond market wants to see more than that.
