US CPI Inflation Stays Elevated At 3.4%, Driven By Higher Energy Prices

US CPI inflation remained elevated and stood at 3.4% in August 2026, in line with expectations (Bloomberg median poll at 3.4%). On a monthly basis inflation picked up, with headline CPI rising to 0.4% from 0.1% in July, while core CPI increased to 0.3% from 0.2%. On a yearly basis, core inflation moderated to 2.4% from 2.5% in July, while core services remained elevated at 3.0%. The pick-up in headline inflation was largely driven by gasoline prices, which accounted for over one-third of the monthly increase, reflecting volatility in global crude oil prices amid renewed Middle East tensions.

Energy Prices Rebound Sharply, While Food Inflation Faces Supply-Side Risks

Food inflation remained elevated at 2.7% on a yearly basis in August, although marginally lower from previous month's reading of 3.0%. The outlook has become increasingly uncertain, with weather-related risks emerging as a key concern. A potential Super El Niño is expected to weigh on global crop production, while higher fertilizer and energy costs could add further upside pressure to food inflation.

Energy prices also reversed their recent decline, rising 16.3% a yearly basis, while gasoline prices increased 27.4% on a yearly basis. The renewed tensions in the Middle East continue to disrupt global oil supply, while dwindling oil reserves including the US could further tighten supply conditions and add to upward pressure on energy prices.

Core Inflation Remains Contained, Even As Shelter Costs Remain Sticky

Core CPI rose 0.3% month-on-month in August, up from 0.2% in July, while the year-on-year rate moderated to 2.4% from 2.5%. Shelter, the largest component in the core basket, increased 0.3% month-on-month and remained elevated at 3.0% year-on-year, contributing about one-third of headline inflation. Elevated bond yields and mortgage rates continue to weigh on housing affordability, which could keep shelter costs under pressure even as broader inflation remains relatively stable. Meanwhile, airline fares rose 2.7% and motor vehicle maintenance and repair increased 1.1%, adding to core services inflation, while medical care services declined 0.2% and provided some offset.

August 2026 CPI inflation came in line with market expectation but remained elevated at 3.4% as renewed tensions in the Middle-East pushed global energy prices higher. With geopolitical uncertainty continuing to linger, inflation is expected to remain elevated, with additional upside risks from food inflation amid weather-related disruptions and a potential pickup in rent inflation, as higher mortgage rates continue to weigh on housing affordability in the US.

At Jackson Hole, Fed Chair, Kevin Warsh reiterated the importance of restoring price stability as inflationary pressures continue to dominate - increasing the probability of a rate hike in the upcoming policy. Markets have largely priced in the expected rate hike, with greater focus now shifting towards the Fed Chair's commentary and whether he chooses to provide any forward guidance.
