June's biggest monthly price drop since April 2020 sent Treasury yields lower but the odds of a September hike complicate the picture
The June consumer price index delivered the largest monthly decline in more than six years Tuesday, pulling Treasury yields lower and briefly easing pressure on the Federal Reserve.
Data from the Bureau of Labor Statistics (BLS) showed the Consumer Price Index for All Urban Consumers (CPI-U) fell 0.4% in June, the steepest single-month drop since April 2020.
The 12-month rate eased to 3.5%, down from 4.2% in May, the highest reading since April 2023.
Wall Street had forecast a 0.2% monthly decline and an annual rate of 3.8%, making the miss one of the more significant inflation surprises of the year.
Sam Williamson, senior economist at First American Financial Corporation, said the report marked a genuine turning point in tone, even if not in Fed policy.
"Inflation came in noticeably cooler than expected last month, offering some much-needed relief after months of growing concern that price pressures were reaccelerating," Williamson said.
The report landed alongside congressional testimony from Federal Reserve Chair Kevin Warsh, who left little room for optimism.
"The Fed's number one objective is to get monetary policy right — or as near to it as we possibly can," Warsh said.
"That is our clear and constant aim, the star we steer by. And if we get policy right — and we will — the inflation surge of the last five years will be a thing of the past."
What it means for yields and mortgage rates
The 10-year Treasury yield — the primary benchmark shaping 30-year fixed mortgage rates — fell more than 3 basis points to 4.579%. The 2-year note dropped more than 6 basis points to 4.202%.
Energy drove the retreat. The energy index slumped 5.7%, its largest monthly drop since April 2020, led by a 9.7% decline in gasoline prices, per BLS data.
The bigger story, Williamson argued, was what happened underneath the headline.
"Stripping out the volatile food and energy categories, core CPI held flat — its weakest reading since May 2020 — as prices fell for auto insurance, apparel, and used cars," he said.
"Even shelter, long the most stubborn component, cooled to a 0.1% gain, its smallest since January 2021."
The probability of a July rate hike collapsed from 42% to 17% in a single session, per CME FedWatch data, though traders still place roughly 60% odds on a hike by September.
Minutes from the June 16–17 Federal Open Market Committee (FOMC) meeting, released Wednesday, show policymakers split between scenarios that would call for rate hikes and those that would allow for cuts.https://t.co/Ds9u9XiGMK

The Middle East factor
The ceasefire that helped push oil roughly 25% lower in June broke down last week after fresh US-Iran strikes, with crude rising Monday and again Tuesday. Energy shocks have been the dominant inflationary variable throughout 2026.
For brokers advising rate-sensitive clients, Williamson offered a measured read on where the housing market stands.
"For home buyers, the key takeaway is less about relief on the horizon and more about the absence of a new setback," he said.
"Because mortgage rates often take their cues from the inflation outlook, a hotter report could have pushed borrowing costs higher and stretched affordability even further. Instead, today's data suggest rates aren't likely headed higher in the near term. That's not the catalyst the housing market needs, but it's one less headwind for a recovery still searching for momentum."
With the key Fed calendar milestones shaping Kevin Warsh's opening months as chair, August's CPI print and September's rate decision among them, the policy question is far from settled.
