On Monday morning you fill the tank on your way to work and the pump number climbs faster than usual. It’s not your imagination: on Wednesday, October 14, the Bureau of Labor Statistics (BLS) published the September inflation data, and gasoline was the star of the show. Annual inflation came in at 3.7%, up from 3.4% in August.
This is the number the whole country —including the Federal Reserve— watches to make decisions. Here’s what went up, what didn’t, and what it means for the wallet of a family like yours.
The data at a glance
- The Consumer Price Index (CPI) rose 0.6% in September (seasonally adjusted), after rising 0.4% in August.
- Over 12 months, prices rose 3.7%, versus 3.4% annually in August.
- Core inflation —which excludes food and energy for being more volatile— rose 0.3% in the month and 2.6% over the year (from 2.4%).
What went up: gasoline rules
Gasoline rose 9.1% in a single month and, according to the BLS, explains more than half of the monthly increase of the entire index. Energy as a whole rose 5.2% in the month. Housing (the shelter component, which includes rents) rose 0.4%.
In other words: this month’s inflation jump didn’t come from a little bit of everything; it came mostly from the pump.
What didn’t go up: food gave a break
Food stayed unchanged in September: groceries fell 0.1%, while eating out rose 0.2%. It’s not a drop you’ll feel in your wallet, but after months of increases, a flat month for groceries is good news.
Core inflation of 2.6% annually —without gasoline and food— shows that, setting energy aside, prices keep rising, but at a more moderate pace.
What it means for your wallet
Think of a typical Hispanic family with two working adults:
- Gasoline for the commute: this is the direct hit. If you drive every day, that monthly 9.1% shows in every fill-up.
- Rent: the housing component rose 0.4% in the month. If your lease renews soon, that’s the number your landlord is also watching.
- Groceries: a month without increases doesn’t lower prices, but it does give the budget a breather. It’s a good time to compare prices across stores, which is where you save the most week to week.
The context: the number the Federal Reserve uses
The CPI is the official thermometer of inflation in the United States and the number the Federal Reserve follows closely for its monetary policy decisions. Without speculating on what it will do: when inflation accelerates, the cost of living rises for everyone, and it’s felt first at the gas pump and then across the rest of the basket.
What to do today, in order
- Review this month’s budget with your actual gasoline spending: it’s the item that moved the most.
- If your rent renews in the coming months, get ready with the housing data (+0.4% monthly).
- Compare grocery prices across stores: with food flat this month, the differences between stores are your best savings.
- If prices are squeezing your budget, check your tax withholding: a timely adjustment avoids surprises in April.
- Calculate how much really reaches your pocket every paycheck with the net salary calculator.
