Some of Wall Street’s biggest bond-fund managers say financial markets are underestimating the risk that the US war in Iran will cause a sharp slowdown in an already sputtering economy.

As oil pushes over $116 a barrel and the conflict shows little signs of ending, traders have largely focused on the inflation shock. That has sent the US Treasury market toward the deepest monthly loss since October 2024 as investors brace for the possibility that the Federal Reserve will push interest rates higher before the year is out.

“Every day that this conflict persists brings us closer to the market being forced to consider the more negative implications for growth, which should ultimately push Treasury yields lower,” said Kelsey Berro, a fixed-income portfolio manager at JPMorgan Asset Management. “Yields broadly have risen enough to be attractive.”
Treasuries rallied Monday, sending the 10-year benchmark yield three basis points lower to 4.40%. The two-year rate fell by a similar margin to 3.89%. Traders will scrutinize an appearance by Fed Chair Jerome Powell in a moderated discussion at Harvard University later Monday for further clues on how he views the risks ahead.
Economists have started to
Such pessimism is typically positive for bonds because it increases the likelihood that the Fed will reduce rates to stimulate the economy. But that hasn’t been the case this time because traders expect the energy-price spike to tie the hands of a central bank that has already been contending with inflation that’s stubbornly above its target.
The result has been a fierce selloff that’s sent bond yields surging. Rates on two- and five-year Treasuries have jumped by more than half a percentage point since the US bombing started late last month. Thirty-year yields have climbed to the cusp of 5%, not far below the peak in 2023, after the Fed had pushed rates to a more than two-decade high.
Much of that reflects anticipation that elevated energy prices will drive up the cost of all kinds of goods, with the OECD warning last week that US consumer prices could jump by 4.2% this year. That, in turn, is making investors demand higher payouts to keep their returns from being eroded by inflation.
Yet some long-time bond investors say the selloff has created an opportunity to lock in elevated yields as the inflation worries overshadow the threat to growth.

“What tends to begin as an inflation shock can quickly migrate into a growth shock,” said Daniel Ivascyn, the chief investment officer of Pimco, which has over $2 trillion of assets. “And we are on the cusp of seeing a significant weakening in the economy.”
The economic risks were already building up before the war. The job market has continued to slow since President Donald Trump returned to the White House and upended global trade with his tariffs. Employers cut 92,000 jobs in February and the March figures — due to be released Friday — are expected to show only a partial rebound, with payrolls expanding by 60,000. And markets have been
Now, markets are hanging on a four-week-old war that’s effectively shut down oil shipments through the Strait of Hormuz. That is already being passed along to consumers, with the price of gasoline hitting the highest since the post-pandemic inflation surge.
At BlackRock Inc., Rick Rieder, who oversees more than $2 trillion as the head of fixed-income investments, said he thinks the Fed
“We’ll see what happens over the next couple of weeks — and then I want to jump in and buy some stuff,” he said during an interview on Bloomberg Television.
The futures market indicates that traders are ruling out any rate cuts from the Fed in 2026, anticipating it will likely remain on hold. On Monday, the market was pricing in a roughly one-quarter chance of a quarter-point hike later in the year.
As 30-year yields drifted higher, Ed Al-Hussainy, portfolio manager at Columbia Threadneedle, said he started buying more long-dated bonds. He anticipates that those yields will ultimately come down if the Fed adds another drag to the economy by pushing up short-term rates. They fell two basis points on Monday, to 4.94%.
“The more the Fed leans into tightening policy, the more damage the long end of the curve has to price to aggregate demand and inflation premia,” he said.
