A brutal week of inflation data sent long-term bond yields to their highest point in nearly a year, complicating the new Fed chair's first hours in the job
The bond market handed Kevin Warsh a difficult welcome gift on his first day as Federal Reserve chair.
Treasury yields surged across the curve on Friday as a week of stubborn inflation readings combined with rising energy costs pushed long-term borrowing costs to levels not seen since last spring.
The 30-year bond yield jumped more than 10 basis points to 5.114%, its highest since May 22, 2025, while the 10-year note — the primary benchmark for US mortgage rates — climbed more than 11 basis points to 4.575%.
For American mortgage brokers already navigating a volatile rate environment, the moves signal that relief is not arriving anytime soon.
The US Senate confirmed Warsh by a vote of 54-45, mostly along party lines, handing him one of the most consequential economic jobs in the world. He arrived, however, with the inflation picture deteriorating rapidly beneath him.

An inflation problem that won't wait
The 30-year fixed mortgage rate averages roughly two percentage points above the 10-year Treasury yield, meaning any sustained climb in bond yields feeds directly into what borrowers pay at the closing table.
With the 10-year now approaching 4.6%, rate quotes in the high 6s are increasingly likely, a prospect that dims hopes for a meaningful recovery in purchase volume through the summer.
The inflation data driving those yields has been unambiguous. Consumer prices rose 3.8% annually — the highest reading since May 2023 — while producer prices surged 6% year-over-year, the sharpest wholesale cost increase since late 2022.
Import costs climbed 4.2% over the same period, with oil above $100 per barrel and shelter inflation doubling in April, adding pressure across virtually every consumer-facing category.
California-based broker Shant Nurani, speaking to Mortgage Professional America earlier this year, framed the dynamic plainly: "What people don't realize is war is inflationary. Because you have spikes in oil prices. The other part of that is when we go into war, the likelihood of the Fed needing to print money goes through the roof." That warning, issued in early spring, has since proved prescient.
Energy markets worsened matters further on Friday. West Texas Intermediate crude rose to $104.39 a barrel, up $3.22 on the day, while Brent crude hit $108.30.
The catalyst was a lack of meaningful progress between president Donald Trump and Chinese president Xi Jinping at a meeting this week, leaving traders without the diplomatic signal markets have been hoping for.

The challenge facing the new Fed chair
Peter Boockvar, chief investment officer of One Point BFG Wealth Partners, captured the bind facing Warsh in a Friday morning note.
"Inflation is still a problem… debts and deficits matter and sovereign bonds that are heavily owned by foreigners are now a source of funds," he wrote.
"Long end rates are now in control of monetary policy. I wish Kevin Warsh the best… but he will still be subject to his surrounding macro circumstances."
Markets have already priced in a 98% probability that the Fed will leave rates unchanged at its June 17 meeting, while futures markets have raised the probability of a rate hike by year-end to approximately 30%, according to CME Group data.
Warsh now faces the task of appeasing president Trump, who has long pushed for lower rates, while dealing with a divided Federal Open Market Committee and navigating an economy that has made it hard to achieve the Fed's dual mandate of maximum employment and stable prices.
