Inflation rose to 3.7% in September as gas prices jumped
Web StoryWatch this story in 15 seconds →Key takeaways
- US prices rose 3.7% over the past year, up from 3.4% in August, according to the Labor Department.
- Gas prices jumped 9.1% in one month. They drove over half of the monthly rise.
- Core prices also rose faster. That raises the chance of another Fed rate hike.
US prices rose faster in September. Annual inflation hit 3.7%. Gas prices drove most of the jump.
The new numbers came out on Wednesday, October 14. They came from the Bureau of Labor Statistics. This office tracks prices across the US. Its report is called the Consumer Price Index, or CPI.
The CPI tracks the price of everyday goods and services. It covers gas, food, rent, clothes, and more.
The headline number was higher than most had hoped. It was also higher than August. But gas was not the whole story.
Other prices rose too. This article explains what happened in plain words. It also explains why it matters and what may come next.
What happened
Prices rose 0.6% from August to September. That is the month to month change. Over the past year, prices rose 3.7%.
That is the year over year change. Year over year means prices versus the same month last year. In August, the yearly rate was 3.4%.
So the pace picked up.
The yearly number came in above the forecast. Economists polled by Reuters had forecast 3.6%. They had forecast the monthly rise at 0.6%.
That monthly forecast was right. The yearly result was hotter than they had hoped. Fox Business reported the same gap.
It said the yearly figure beat the 3.6% estimate from economists polled by LSEG.
Gas was the biggest driver by far. Gas prices rose 9.1% in September alone. That is the figure from the Bureau of Labor Statistics.
Gas prices were up 34.2% from a year ago. Gas drove over half of the total monthly rise, according to the BLS.
At the pump, the pain was easy to see. The average gallon of gas cost $4.33. That was up from $4.31 a month ago. These figures came from AAA, which tracks daily pump prices.
Diesel cost even more. It averaged $6.29 per gallon, up from $6.23. One analyst said 2026 has now seen 158 days with gas above $4 per gallon. That analyst was Patrick DeHaan of GasBuddy.
He shared the count in a post on X.
Why did fuel jump so much? Global tensions weighed on energy prices. That is what Al Jazeera reported.
Tensions between the US and Iran played a part. The Russia and Ukraine war played a part too. Kyle Moore is chief economist at The Century Foundation.
He said the war in Iran keeps disrupting supply chains. He said this pushes up food and fuel prices.
Food gave shoppers a small break. The food index was flat in September. That means overall food prices did not move.
Meals out rose 0.2%. Grocery prices fell 0.1%. Those two moves offset each other.
Inside the grocery store, results were mixed. Poultry prices rose 0.7%. Fruit and vegetable prices rose 0.5%.
Juice prices rose 1.1%. But milk prices fell 2.1%. Beef prices fell 0.9%.
Those figures came from Al Jazeera.
Housing costs kept climbing. Shelter costs rose 0.4% in September. They had risen 0.3% in August.
Shelter means rent and the cost of housing. It is a large part of most family budgets. When shelter rises, many people feel it fast.
Core prices also moved up. Core CPI leaves out food and energy. Food and energy prices swing a lot.
Core gives a steadier view of price trends. Core prices rose 0.3% in the month. Over the past year, core prices rose 2.6%.
In August, the yearly core rate was 2.4%. So core inflation also sped up.
Core also beat the forecasts. Economists had forecast a 0.2% monthly rise. They had forecast a 2.5% yearly rise.
Both results came in hotter. That matters because core shows pressure beyond fuel. It shows that price rises are spreading wider.
One more item stood out. Prices for computer software and accessories jumped 28% from a year ago. That is a very large yearly rise.
Heavy spending on AI played a part. Rami Cassis is principal of Parabellum Investment. He told Al Jazeera that the AI boom is playing a huge part.
He pointed to large sums poured into data centers, AI firms, and models.
Why it matters
This report touches daily life in three ways. It hits wallets, loans, and votes. Each one is worth a short look.
First, wallets. Gas and housing are costs most people cannot skip. When gas jumps 9.1% in a month, trips cost more.
Work trips cost more. School runs cost more. When shelter rises too, less cash is left for other needs.
Food prices were flat. That helped a little. But food costs had already risen in past months.
Flat food prices do not erase past rises.
Second, loans. The Fed watches inflation closely. The Fed is the central bank of the US.
Its job is to keep prices steady. Its goal is 2% inflation. The current rate of 3.7% is well above that goal.
Last month, the Fed raised rates by 25 basis points. A basis point is one hundredth of a percent. The move lifted the target range to 3.75% to 4.00%.
It was the first hike in three years, according to Al Jazeera.
Higher rates make loans cost more. This includes home loans, car loans, and card debt. Mortgage rates have already been climbing.
When the Fed raises rates, loan costs tend to follow. Savers face a different problem. Inflation can eat the value of savings when prices rise faster than interest paid.
A top Fed official voiced worry after the report. Austan Goolsbee leads the Chicago Fed. He called the September data discouraging.
He spoke in an interview with Yahoo Finance. He said services inflation shows little sign of improvement. Services means haircuts, repairs, and other paid help.
He said the central bank will get inflation back to its 2% target. Reuters reported his remarks.
Markets reacted the same day. The Nasdaq fell 0.8%. The S&P 500 dropped 0.6%.
The Dow Jones Industrial Average was roughly flat. Those were midday moves reported by Al Jazeera. A fall in stocks does not prove a trend.
But it shows that investors took the report hard.
Third, votes. The midterm elections are on November 3. This was the last big inflation report before the vote. A Reuters/Ipsos poll showed a clear mood.
About 78% of Americans blamed President Donald Trump's policies for rising prices. The poll named tariffs on imports and the war with Iran. Reuters reported the poll result.
The two parties read the report in very different ways. The House Democratic Caucus posted on X. It said Trump had promised to lower costs.
It said the opposite has happened. It called the president a total failure. Senate Minority Leader Chuck Schumer also posted on X.
He said higher prices keep hitting the American people. Fox Business reported both posts.
The White House pushed back. A White House official told Fox News Digital that Trump is bringing inflation down. The official noted that food prices were flat in the month.
White House spokesman Matthew Middleton gave a statement. He said Trump has an aggressive, pro-growth economic agenda. He said the plan has blunted the inflation crisis from the Biden years.
He also said the Iran conflict has caused short-term disruptions. Fox Business reported both responses.
Retirees had one more reason to watch this report. The Social Security Administration uses CPI data to set yearly benefit changes. It uses wage-earner price data from the third quarter.
It uses this to set the cost-of-living change for 2027. The Senior Citizens League projected a 3.5% rise for 2027. That would be up from 2.8% in 2026. It would lift the average monthly benefit for retirees by $67.90. The new average would be $2,007. Reuters reported the projection. The agency was set to announce the change later on Wednesday. Our Social Security COLA explainer breaks down how this yearly change works.
What happens next
All eyes now turn to the Fed. The Fed meets on October 27 and 28. It will decide whether to raise rates again. Before the report, markets saw about a 22% chance of an October hike.
That figure came from CME Group's FedWatch Tool. After the report, the odds moved up. FedWatch showed a 52.9% chance of no change.
It showed a 47.1% chance of a quarter-point hike. Al Jazeera reported the new split.
A hike is not certain. A hold is not certain either. The Fed will weigh more data before it votes.
Jobs data will matter. Wage growth will matter. The next price reports will matter too.
If price pressure stays broad, a hike grows more likely. If gas prices cool, pressure on the Fed may ease.
Gas prices will stay a key watch item. They depend on oil markets and global tensions. They also depend on supply chains.
Any easing in tensions could help pump prices. Any new shock could push them up again. Drivers will feel the result first.
Voters will also have a say. The midterms are on November 3. Cost of living is a top issue for many voters. Both parties will keep making their case.
The inflation report gave each side fresh lines. But the vote will turn on much more than one report.
For households, the near term is about cash flow. Gas and housing take a big share of pay. Food prices held flat in September.
That is a small help. But budgets may stay tight if fuel stays high. Tracking weekly spending can show where money goes.
Small shifts, like fewer trips or shared rides, can cut fuel use. These are personal choices, not financial advice. Each household must judge its own case.
The big picture is still unclear. Inflation rose in September. Core inflation rose too.
The Fed must now decide how hard to push back. Its next meeting will give the first answer. The months after that will show if prices cool or keep climbing.
