US Inflation Gauge Stays at 3.7 Percent Amid Iran Conflict

The Commerce Department reported Wednesday that prices rose 3.7% in July compared to a year earlier, matching the June reading and remaining well above the Federal Reserve’s 2% target [1]. This persistent inflation, fueled by geopolitical tensions and trade policy, is straining household budgets and complicating the Federal Reserve's interest rate strategy just 10 weeks before the midterm elections [2].

Inflation drivers and policy implications

The July PCE index—the Fed’s preferred inflation gauge—remains elevated, having risen from 2.9% in February when the U.S. and Israel first engaged in conflict with Iran [1]. While gas prices fell in July, the overall index was propped up by rising costs in services, including health care, utilities, and financial services [2]. Core inflation, which excludes volatile food and energy costs, held steady at 3.3% in July, a notable increase from the 2.6% level recorded before President Donald Trump implemented broad tariffs in April 2025 [1].

The data highlights a growing tension between consumer spending and economic growth. While businesses have ramped up investments in AI infrastructure, much of that capital has flowed toward imports, contributing to a modest 1.5% economic growth rate in the second quarter [2]. Meanwhile, inflation-adjusted incomes rose only 0.2% over the last year, leaving many Americans feeling the weight of high prices despite the cooling of post-pandemic inflation peaks that once topped 7% in 2022 [1].

Adjustments to measurement and market response

The Commerce Department plans to revise its inflation calculation methodology starting next month to better isolate consumer spending from business-related software costs and portfolio management fees [2]. Economists anticipate these technical adjustments could lower the annual PCE inflation reading by approximately 0.2 percentage points [1].

The persistence of inflation has kept upward pressure on long-term interest rates, with 30-year Treasury yields recently hitting a 19-year high [1]. In response to the volatility, Treasury Secretary Scott Bessent announced that the government will double its buybacks of 10-to-30-year bonds starting next month to help stabilize yields [2].

What to watch

• Fed Chair Speech: Investors are monitoring Federal Reserve Chair Kevin Warsh’s upcoming address in Jackson Hole, Wyoming, for signals on whether the central bank will maintain current interest rates or pivot to further hikes [1].
• August Energy Data: With national average gas prices ticking up to $4.10 per gallon recently, analysts are tracking energy costs as a primary driver for the next inflation report [2].
• Methodological Shift: Watch for the Commerce Department’s revised PCE figures next month to determine how much of the current inflation "stickiness" is attributable to measurement methodology versus actual price pressures [1].

Whether the upcoming technical revisions to the PCE index will provide the Federal Reserve with the clarity needed to resolve its internal policy split remains an open question. Until then, the combination of geopolitical risk and trade uncertainty continues to keep borrowing costs elevated for consumers and businesses alike.
