US equity indexes rose amid a broad-based rally led by communication services and technology, after August's consumer price inflation data sparked a rise in short-term government bond yields and crude oil slumped.
The Nasdaq Composite jumped 1.2% to 26,391.5, the S&P 500 climbed 1.1% to 7,671.1, and the Dow Jones Industrial Average advanced 1.1% to 52,642.2 after midday Friday. All sectors rose, with industrials among the top gainers.
The consumer price index rose 0.4% month on month, the fastest pace since May and above July's 0.1% gain, the Bureau of Labor Statistics data showed Friday. The move matched the Bloomberg-polled consensus. Core inflation, which excludes the more volatile food and energy components, jumped to a four-month high of 0.3%, exceeding market projections for an unchanged 0.2% growth.
On an annual basis, headline inflation held steady at 3.4%, as expected. The annual core measure eased to 2.4% from 2.5%, also in line with projections.
"Although headline inflation met expectations, core inflation came in slightly hotter than anticipated, ending a three-month run of softer readings," Thomas Feltmate, senior economist at TD Economics, said in a report. "The pickup was concentrated in non-housing services, which posted its strongest monthly gain since January and is still running north of 3% on a twelve-month basis -- underscoring the stickiness in this component of inflation."
Most US Treasury yields rose in midday trading. The two-year jumped 7.8 basis points to 4.63%, the highest since mid-2024. The 10-year yield edged up 1.1 basis points to 4.96%, the strongest level since October 2023.
Further in economic news, the University of Michigan's preliminary consumer sentiment index fell to 47.8 in September from 51.7 in August, versus the 51.0 expected in a survey compiled by Bloomberg. Respondents set one-year inflation expectations at 4.6%, up sharply from 4.0% in August, while five-year inflation expectations increased to 3.4% after remaining at 3.3% for three straight months.
Yemen's Iran-aligned Houthis reached Perim island in the Bab el-Mandeb Strait on Friday, four Yemeni government sources told Reuters, moving to tighten their grip on an important shipping route.
A Houthi spokesman said they will allow international vessels to pass through Bab al-Mandeb except Saudi ships, which are being blocked, Al Jazeera, a Middle Eastern broadcaster, reported.
The front-month US West Texas Intermediate crude oil contract slumped 3% to $99.46 per barrel, and global benchmark North Sea Brent dropped 3.1% to $104.29 per barrel.
