Treasury Secretary Scott Bessent dismissed concerns about rising U.S. yields in an interview with CNBC on Monday.

Speaking on the sidelines of the G20 finance ministers’ meeting in Asheville, North Carolina, Bessent noted that Fitch Ratings reaffirmed government debt’s AA+ rating last month and said the U.S. bond market remains the “best performing market” in the world.
The rise in borrowing costs comes after the United States and Iran launched retaliatory strikes in recent days around the Strait of Hormuz, energy prices rose and inflationary pressures returned to investors’ attention.

Steve Englander, head of global G10 currency research and North American macro strategy at Standard Chartered, said the six-month dispute, combined with the Supreme Court’s tariff ruling that canceled about 40% of additional tariff revenue, had increased pressure on the bonds.
Yields across the curve remain under upward pressure, Englander said on CNBC’s “Squawk Box Europe” on Tuesday, adding that the U.S. is not alone in facing deficit problems.
“I don’t think what Mr. Bessent calls ‘best performance’ is the same as good performance,” Englander said. “Everyone has a budget deficit problem. I don’t see any reason to cheer.”

The rise in the cost of UK government debt comes as British Prime Minister Andy Burnham is expected to later tell MPs that stronger public control is the only way to boost the country’s growth.
Burnham, who became Britain’s seventh prime minister in a decade in July, is said to be considering legislation that would make it easier to bring struggling utilities into public ownership, the Guardian newspaper reported on Tuesday. UK bond yields are also catching up with global bond yields after Monday’s bank holiday.
