Treasury Secretary Scott Bessent is set to deliver a prime-time speech at the Republicans’ midterm convention in Dallas on Wednesday, the first time in 50 years that a sitting Treasury secretary has taken the stage at a national political convention, CNBC reported. The appearance puts Bessent in an unusual position: the same market credibility he relies on to manage the roughly $28 trillion market for U.S. government debt is now entwined with an openly partisan role.
The last Treasury secretary to speak at a national convention was William E. Simon, who addressed the Republican National Convention in 1976. Since then, the norm has held that Treasury secretaries stay off the convention stage to preserve their standing with investors. The Dallas gathering is also the first midterm convention the GOP has held.
Why the Role Is So Sensitive
Unlike the Federal Reserve, the Treasury Department cannot print money, which makes the secretary’s credibility its primary source of influence in markets. “Treasury generally doesn’t have a tremendous power but for the market credibility of the Treasury secretary,” said Stephen Myrow, managing partner of Beacon Policy Advisors and a former advisor to Treasury Secretary Hank Paulson, according to CNBC.
Bessent is scheduled as the final government speaker before Trump, appearing between House candidates from Arizona and Michigan and a woman the convention agenda bills as an “everyday American, working mother and economic policy advocate.”
Buybacks and Rising Yields
His speech lands on the same day the Treasury Department said it would buy back as much as $6 billion in long-term Treasury debt this week, with a cap of at least $4 billion in operations later this year. The department launched the buyback program in 2024 to address thin trading in some long-term debt.
Bessent has described the operations in broader terms. At an event Tuesday organized by Breitbart, he said there was a “fever that was building” in the markets and that he acted to stem it. The intervention initially worked: after Bessent announced enhanced buybacks on Aug. 19, Treasury yields fell, following days of headlines about a global sell-off in government bonds.
The effect was short-lived. Yields on long-term Treasury debt rose Wednesday after the department disclosed the buyback sizes, which had been anticipated. The 10-year Treasury note yielded 4.84% midafternoon Wednesday, higher than at any point during Trump’s term. Higher yields can benefit savers earning income from holding debt, but they squeeze borrowers facing higher costs on new mortgages and auto loans.
A Different Kind of Treasury Secretary
Some predecessors worked hard to avoid overt politics. Former Treasury Secretary Janet Yellen, who served under President Joe Biden until Trump took office in 2025, told CNBC she was never asked to speak at an explicitly political event and was careful not to do so to avoid violating the Hatch Act, the 1939 law limiting political activity by most executive branch employees. She noted that other Biden appointees did speak at political events while observing those rules.
Others crossed into convention politics only at specific moments. Treasury Secretary James Baker appeared in a video at the 1988 Republican National Convention and resigned effective that day to run George H.W. Bush’s presidential campaign. Robert Rubin spoke at the 2000 Democratic convention a year after stepping down as Bill Clinton’s Treasury secretary.
Bessent has been aggressive in using his public profile against the administration’s political adversaries. At the Breitbart event Tuesday, he said, “I say sometimes I feel like an emergency room doctor. The Biden economy just was like American people got hit by a truck.” Workers are doing much better under Trump, he added, saying the bottom 25% of earners have seen greater wage gains than the top 25%.
The Treasury Department did not respond to requests for comment about the political nature of Bessent’s speech, CNBC reported. Bessent, a 64-year-old former hedge fund trader, has waved off questions about political ambitions beyond his current job. Speaking to students at Southern Methodist University on Tuesday, he said he had fielded calls after the death of Sen. Lindsey Graham in July urging him to run for the South Carolina seat. “They said, ‘Oh, you should run for his seat,’ and I said, ‘you know what, I have one very demanding boss right now. I do not need 5.5 million South Carolinians as boss,'” he recalled.
Bessent is not a natural orator — his delivery is sometimes seen as awkward, and he tends toward financial jargon — yet he has risen to the top of an administration where loyalty and aggressive defense of the president’s policies are constantly gauged.
“We don’t have a typical, traditional president. So we wouldn’t expect to have a traditional Treasury secretary,” Myrow said. But if markets come to see Bessent as putting politics first, Myrow warned, he could get caught in a cycle of escalating demands from the president and diminishing effectiveness. “The real value Bessent has for Trump is his credibility in the market,” Myrow said. “If he ends up sufficiently losing market credibility, he’s burning up the value he provides to Trump and the country.”
