US inflation accelerates to 3.7% as energy prices surge before midterm elections
US consumer-price inflation rose to 3.7% in the year to September, above forecasts and up from 3.4% in August. Petrol prices increased 34.2% over the year and accounted for more than half of September’s monthly inflation increase, while core inflation was 2.6%. The figures arrive before midterm elections dominated by cost-of-living concerns. The Federal Reserve will watch whether energy costs spread into other prices; the report also notes tariffs have raised consumer-goods prices.

What matters
- Petrol prices rose 9.1% in September and 34.2% over the year.

- The Social Security Administration announced a 3.6% benefit increase for 2027.
Tariffs and prices
New York Fed research cited in the report found that US businesses absorbed nearly 90% of added tariff costs, with each percentage-point increase in average tariffs associated with nearly a 0.25% consumer-goods price increase after one year.
Context & caveats
- The report attributes the recent energy shock to disruption linked to the US-Israel conflict with Iran; broader spillover into food and other prices remains uncertain.
