The United States economy experienced a more significant slowdown than anticipated in the second quarter, with growth cooling as an inflation surge took hold amid the early months of the Iran war. The economy expanded at an annualized rate of 1.5% in the three months ending in June, a decrease from the 2.1% growth recorded in the previous quarter. This figure fell short of economists' expectations, though it still outpaced the 0.5% annualized gross domestic product (GDP) growth seen in the final quarter of 2025.

The data release covers a period that followed a major global oil shock triggered by the conflict in the Middle East. The national average price for a gallon of gasoline reached as high as $4.56 in May, according to AAA data, before experiencing some moderation after a preliminary peace agreement was reached last month.

Annual inflation has now risen to 3.5%, exceeding the Federal Reserve's target rate of 2% by more than a full percentage point. Despite these elevated costs for consumers and businesses, the labor market has demonstrated resilience, with hiring proving stronger than many economists had predicted.

The implications of this economic slowdown and persistent inflation are significant. The combination of rising prices and a robust job market has increased the likelihood of an interest rate hike, according to futures markets. Such an increase could dampen economic activity in the coming months by raising borrowing costs for corporations.

In recent quarters, substantial investment in artificial intelligence has been a key driver of national economic growth. A surge in AI spending accounted for approximately two-thirds of GDP growth in the first half of 2025, according to JPMorgan Asset Management, surpassing the contribution from millions of U.S. consumers. Major corporations have been directing significant funds into the development of the necessary chips and data centers to support AI technologies.

The Federal Reserve was scheduled to announce its latest decision on interest rates on Wednesday afternoon, shortly before the GDP data was released. The benchmark interest rate currently stands between 3.5% and 3.75%. While this represents a notable decrease from a peak in 2023, borrowing costs remain considerably higher than the 0% rate established at the beginning of the COVID-19 pandemic.

Fed Chair Kevin Warsh, who assumed leadership of the central bank this summer, has publicly committed to reducing inflation. He stated last month that persistently high prices are a burden on the American people and affirmed that the committee would prioritize delivering price stability.

Unresolved questions remain regarding the long-term impact of the Iran war on global supply chains and energy prices, as well as the Federal Reserve's strategy for balancing inflation control with economic growth in the face of these geopolitical and economic pressures.
