US inflation climbs to 3.7% as fuel prices surge
Consumer prices rose faster than expected in September, complicating the Federal Reserve’s next decision before November’s midterm elections.

US consumer price inflation accelerated to 3.7% in the year to September, according to figures released on Wednesday. The monthly increase was driven largely by fuel costs, while underlying inflation also edged higher, keeping pressure on the Federal Reserve and the White House.
The Consumer Price Index rose 0.6% between August and September after increasing by 0.4% the previous month, the US Bureau of Labor Statistics said. The annual rate rose from 3.4% in August to 3.7% in September, exceeding the 3.6% increase economists had expected in a Reuters survey.
Fuel was the clearest source of pressure. The petrol index rose 9.1% during the month and accounted for more than half of the overall monthly increase, while the broader energy index rose 5.2%. Food prices were unchanged overall: prices for food consumed at home fell slightly, while restaurant prices increased.
The figures do not by themselves establish why prices moved, but the Associated Press reported that the effect of the Iran war on fuel markets was being cited as one factor. The BLS data show the price movements, rather than attributing them to particular political or international events.
Underlying inflation, which excludes food and energy, rose 0.3% in September and 2.6% over the year. Shelter costs increased 0.4% during the month, while airline fares, used cars, recreation, education, medical care and clothing also recorded increases.
The Federal Reserve targets 2% inflation over the longer term, measured by the separate Personal Consumption Expenditures index. The latest CPI figures therefore do not determine policy on their own, but they add to the evidence that price growth remains above the central bank’s preferred pace.
The Fed’s next scheduled policy meeting is on 27 and 28 October. Reuters reported before the release that investors largely expected interest rates to remain unchanged at that meeting, although the new figures could influence expectations for later decisions.
The report arrives before the US midterm elections on 3 November, when the cost of living is a central political concern. For households, the figures describe the pace at which prices are rising; they do not mean that prices have fallen when the inflation rate slows.
One story, several perspectives
What is established
- US CPI inflation was 3.7% over the year to September, with petrol prices rising 9.1% during the month.
- Core CPI rose 2.6% over the year, excluding food and energy.
- The Federal Reserve’s longer-term inflation objective is 2% on the PCE measure.
- The figures were released before the US midterm elections and ahead of the Fed’s October meeting.
Left
Arguments The left would stress that fuel and food costs hit lower-income households hardest and would favour targeted public support, stronger consumer protection and measures to limit windfall gains where firms benefit from energy shocks. It would be sceptical of relying on interest-rate rises alone.
Values Its priorities are economic security, redistribution and protecting household living standards, especially for people with little ability to absorb higher bills.
Consequences It would warn that aggressive rate rises could weaken employment and housing affordability while doing little to resolve an external energy shock.
Centre
Arguments The centre would emphasise the distinction between a temporary energy shock and persistent underlying inflation. It would support an independent Federal Reserve, careful use of targeted help and decisions based on several months of data rather than one CPI release.
Values Its priorities are institutional independence, evidence-based policy and balancing price stability with employment.
Consequences It would accept that rates may need to remain restrictive while arguing that broad subsidies or abrupt political intervention could prolong inflation.
Right
Arguments The right would focus on the costs of tariffs, public spending and energy-market disruption, arguing that governments should reduce barriers to domestic production and avoid policies that raise business costs. It would generally favour tighter control of spending and a predictable monetary policy.
Values Its priorities are fiscal discipline, market incentives, energy security and limiting government intervention.
Consequences It would warn that prolonged inflation erodes savings and wages, while excessive regulation or untargeted support could keep prices elevated.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

Editor's note
The September CPI figures and component movements are confirmed by the BLS. AP and Reuters provide independent context on fuel prices, the Iran war and market expectations; the data do not prove a single cause for the increase.Sources
