US inflation eases to 3.4% in July as the Fed's September call stays on a knife edge

The U.S. inflation rate slowed in July, with consumer prices up 3.4% from a year ago, down from 3.5% in June, according to the Labor Department. Although this marks a slight decrease from the previous month, it remains higher than before the Iran war began in February, when inflation stood at 2.4%. On a monthly basis, prices rose only 0.1% from June to July.

Inflation has been driven by various shocks, such as President Donald Trump’s tariffs, higher gas prices from the Iran war, and increased investment in artificial intelligence infrastructure that has boosted computer chip prices. The Federal Reserve, responsible for combating inflation, faces the challenge of determining when temporary effects will fade.

Excluding volatile food and energy categories, core inflation also decreased to 2.5% in July, down from 2.6% in June, and rose by about 0.2% monthly, suggesting it may be close to the Fed's two percent goal if this trend continues. The key question for inflation fighters at the Fed is how swiftly these one-time effects will recede.

Analysts suggest if gas prices continue to fall after the Iran war ceasefire, it could further reduce inflation, but it could rise again when August's figures are released. The average gas price in the U.S. is currently $4.04 a gallon, a 16-cent increase from the previous month. Overall, price increases have been above the Fed's two percent target for over five years, suggesting that more than temporary factors are at play.

The increase in service costs, such as healthcare, restaurant meals, and car maintenance, remains a concern as they are generally not influenced by gas prices or AI investment. Many economists and Fed officials are seeking more information to predict inflation's trajectory.
