Gas prices are still rising, but much more slowly
If you pay a gas bill, prices are still higher than a year ago, but only a little. In September 2026, gas prices were 1% higher than 12 months earlier.

This does not mean gas got cheaper. It means the price rise over the past 12 months was smaller than the one recorded a month earlier.

Both figures compare prices with the same month a year before. They are not month-on-month price changes.

How September compares with August
The annual rate fell by 2.5 percentage points between the August and September readings. That is a change in the speed of price growth, not a fall in the price itself.

The facts here cover only these two months, so they cannot show whether September is part of a longer slowdown or a one-off shift.

A household's actual bill also depends on how much gas it uses and which plan it is on. These figures track prices, not bills.

What the figures do not tell us
The data shows the national 12-month change in gas prices for two months only. It does not show differences between states or cities, between retailers, or the dollar amount people pay.

It also does not explain why the rate slowed. The cause cannot be identified from these figures alone.

AI analyst view
Little change expected low confidence next 3 months
Estimate range: 1–2%
Why
- A drop of 2.5 percentage points in a single month is large for an annual rate. Moves like this often come from a base effect, where a price rise from the same month a year earlier falls out of the comparison. That kind of drop usually does not reverse straight away. F1 F2 F3
- With the annual rate now at 1%, there is little room for a further large fall unless prices actually start declining. That makes a reading near the current level more likely than a sharp move in either direction. F1
- Only two monthly readings are available, so the trend is thin. That is why confidence in this view is low. F1 F2
What would change this view
- If the next reading climbs back above 3.5%, the September slowdown was likely temporary.
- If the annual rate falls below 1%, gas prices may be starting to decline outright, which would point to a downward rather than flat path.
This is the AI’s own interpretation of the official figures above, not an official forecast. It may turn out wrong.
Scenarios to watch
- Scenario, not a forecast If the next readings stay close to September's, it would suggest the slower pace of gas price growth is holding rather than being a single-month dip.
- Scenario, not a forecast If a later reading moves back towards August's 3.5%, it would point to September being a temporary low rather than a turning point.
What to check next
- The October 2026 reading of gas price inflation (12-month change), to see whether it stays near 1%.
- Whether the annual rate moves back towards the August figure of 3.5% in later months.
- Any state or city breakdown of gas prices, which these national figures do not show.
