The U.S. economy expanded at a seasonally adjusted annualized rate of 3.4% in the third quarter, beating the 3.1% estimate, the Commerce Department reported Thursday. Price increases accelerated in September, with the annual inflation rate at 3.6%, well above the Federal Reserve's 2% target.

The data comes a day after the Fed voted to keep its benchmark interest rate between 3.75% and 4%. Central bank officials said they can afford to evaluate incoming data before deciding on their next move. Fed Chairman Kevin Warsh said that “the period right in front of us is information rich.”

The personal consumption expenditures price index rose 0.5% in September on a seasonally adjusted basis, the largest monthly gain since March. Excluding food and energy, core PCE rose 0.3% on the month and 3.1% annually, figures the Fed regards as more indicative of long-term trends.

Consumer spending climbed 0.5% in September, slightly below the forecast 0.6% gain, while personal income edged up 0.2%, compared with an expected 0.3%. On a quarterly basis, PCE prices rose 2.1% (headline) and 2.5% (core), down from 5% and 3.3% in the second quarter.

Gross domestic product grew faster than its 2.2% pace in the second quarter. The Commerce Department reported gross private domestic investment soared 19.4%, led by a 20.9% surge in equipment spending and an 8.4% rise in intellectual property products. Real sales to private domestic purchasers, a proxy for underlying demand, rose 4.9%.

September’s price uptick was driven largely by a 9.2% jump in gasoline and other energy goods and a 5.4% rise in energy goods and services broadly. Services prices excluding energy and housing increased 0.4%, and housing costs rose 0.3%.

Initial jobless claims edged lower to a seasonally adjusted 194,000 for the week ended Oct. 24, below the 200,000 estimate and near levels last seen in the late 1960s.

“Net, net, economic growth is powering ahead despite the uncertainty of geopolitical risks and the damage posed to many sectors of the economy by higher energy costs,” said Chris Rupkey, chief economist at Fwdbonds. “The economy was thought to have been a lost cause during much of the current Administration’s time in office, but real GDP has bounced back above a 3 percent run rate in Q3 2026 for the first time in a year.”

Analysis

Why This Matters

  • GDP growth above expectations suggests the economy is resilient despite high inflation and geopolitical headwinds.
  • Persistent inflation above the Fed’s target may delay any rate cuts, keeping borrowing costs elevated for consumers and businesses.
  • Strong investment in equipment and intellectual property, particularly related to artificial intelligence, points to potential productivity gains.

Background

The Federal Reserve targets an annual inflation rate of 2%. In the second quarter of 2026, U.S. GDP grew at 2.2%. The Fed’s benchmark interest rate currently sits between 3.75% and 4%. September’s inflation acceleration followed a previous quarterly slowdown: headline PCE rose 2.1% in Q3, down from 5% in Q2.

Key Perspectives

Fed Chairman Kevin Warsh: The central bank can afford to evaluate incoming data before deciding on its next move and called the period “information rich.” Chris Rupkey, chief economist at Fwdbonds: Economic growth is “powering ahead despite the uncertainty of geopolitical risks and the damage posed to many sectors of the economy by higher energy costs,” noting that GDP returned above a 3% run rate for the first time in a year.

What to Watch

  • The Fed’s next interest rate decision as more data arrives, particularly on inflation and employment.
  • Energy price trends: September’s surge in gasoline and energy goods could spill into broader inflation if sustained.
  • Consumer spending: a slight miss on the September forecast amid rising costs may signal weakening demand.
