• U.S. inflation rose to 3.8% in April, exceeding expectations, as surging gas prices linked to the Iran conflict pushed up consumer costs.
  • Energy-driven inflation is spilling over into transportation, food, and manufacturing, raising fears of broader price pressures and delayed Fed rate cuts.
  • President Trump endorsed a temporary federal gas tax suspension to ease pressure on drivers, as average gasoline prices hit $4.50 a gallon.

Inflation accelerated sharply in April, climbing to 3.8% from 3.5% in March, according to the latest data. The jump was largely fueled by a spike in gasoline prices, which have surged amid escalating tensions between the U.S. and Iran. Average gas prices now stand at about $4.50 a gallon, up from $3.14 a year ago.

The rising energy costs are rippling through the economy. Transportation costs are up, food prices are climbing, and manufacturers are facing higher input costs. Some economists worry that this could further weaken consumer spending, which has already shown signs of cooling.

"The inflation picture is clearly being dominated by energy right now," said one analyst. "Without a deal to stabilize oil markets, we could see inflation persist above the Fed's target."

The Federal Reserve had been expected to begin cutting rates later this year, but the latest inflation reading has pushed those expectations further out. Markets are now pricing in a lower probability of a rate cut before September.

President Trump, who has made energy prices a political priority, said he supports temporarily suspending the federal gas tax to provide relief to drivers. "We want to make sure Americans aren't paying too much at the pump," he said. The White House has not yet proposed a formal plan, and it remains unclear whether Congress would take up the measure.

Efforts to reach the Energy Department for comment on potential supply measures were not immediately successful. The situation in the Middle East remains fluid, with no clear resolution in sight.

Correction: An earlier version of this article misstated the year-ago gas price. It is $3.14, not $3.41.
