The October consumer price index report, scheduled for release at 8:30 a.m. ET on Tuesday, is expected to show month-over-month inflation of 0.3% with core inflation rising 0.2%, according to Bloomberg economist surveys [1]. This represents a potential slowdown from September's 0.6% monthly increase, driven primarily by easing fuel prices that have provided some relief to American consumers [1]. Gas prices declined more than 5% during October, falling from $4.41 per gallon on October 1st to $4.18 by month's end, with prices continuing to trend downward into November to reach $4 per gallon [1].
The inflation data arrives amid significant political consequences, as 84% of voters told NBC News' Exit Poll that they believed higher prices resulted from President Donald Trump's policies, and 39% cited the economy as their top ballot issue in last week's congressional elections [1]. The primary drivers of elevated inflation include global tariffs on imported products and the Iran war launched in February, which has driven regular gas prices up 40% and diesel fuel prices 70% higher than the start of the year [1]. Economists have warned that elevated diesel prices pose particular risks, as diesel is a major input cost for the transportation industry that delivers goods globally [1].
Citigroup economists predict that Tuesday's CPI data will show "stabilizing and falling airfares, and limited pass through of higher energy costs into goods prices," with potential slowing in shelter inflation and services prices [1]. However, the relief may be temporary, as the article notes that even as the oil price surge takes a breather, it may not last long, with International Energy Agency member countries having released 400 million barrels throughout the Iran war [1]. The October 2025 CPI report was skipped entirely due to a U.S. government shutdown that disrupted data collection, meaning the October data will not contain a year-ago comparison [1].
CONCLUSION
October's CPI report is expected to show modest inflation relief driven by declining fuel prices, providing temporary respite from the price pressures that significantly influenced recent election outcomes. However, underlying structural factors including tariffs and geopolitical tensions suggest sustained inflation risks remain, with energy costs potentially resuming upward pressure if current relief measures prove temporary.
