Goldman Sachs CEO David Solomon said recent moves that pushed higher long-term rates in the Treasury market are going to be hard to fight for the Treasury Department and its buyback program. But he also said he wasn't that worried about it.

"This is a longer term trend that is reflective of our fiscal decisions, the growth of the debt overall and the growth of the economy," Solomon told CNBC Monday from the G20 conference.

He said the current yields on long-term Treasurys didn't seem a calamity. He added that he didn't expect pressures on those bonds to create a calamity for the U.S. either. But that doesn't mean he's ignoring the risks.

"We are going to have to adjust," Solomon said. "We are either going to have to drive higher levels of economic growth consistently, given our levels of spending and debt, or we are going to have to adjust our spending policy."

The 10-year Treasury yield was recently trading at 4.76%, up about 0.6 percentage point in 2026.
