The White House won’t even try to explain Trump’s fictional inflation numbers

Trump’s Inflation Claims Clash With the Available Data

Earthguardiansonline.com – Inflation has become a central political vulnerability for President Donald Trump and his party during the midterm campaign, and the president has responded with a series of assertions that do not match widely used price measures.

Trump has repeatedly said that inflation has been stopped and that prices are falling sharply. The available figures point in a different direction: inflation accelerated in September, prices continued to rise, and average prices were 5.4% higher than they were when former President Joe Biden left office in January 2025.

This week, Trump moved beyond broad declarations and offered specific figures that are especially difficult to reconcile with the data. At a rally in Alaska on Tuesday, he said inflation had reached “1.7” over the prior three months while Biden’s “real inflation” was 19%.

“1.7 inflation in the last three months. Think of that, 1.7. He had real inflation; he had real inflation of 19%.”

He repeated the comparison during a Montana rally on Wednesday, more than 12 hours after the newest Consumer Price Index release showed that inflation stood at 3.7% over the previous year in September.

“We inherited the worst inflation in history, think of it, and now, the last three months, we have 1.7 – we have it down to – he had 19%, his real number’s 19%.”

Recent Measures Do Not Show 1.7% Inflation

There is no clear standard inflation measure that produces Trump’s stated 1.7% figure for the last three months. Heather Long, chief economist for Navy Federal Credit Union, said Thursday that the number is not supported by the data.

The most commonly discussed measure is the year-over-year Consumer Price Index. For the three latest months with available CPI readings in 2026, the annual rate was 3.4% in July, 3.4% in August and 3.7% in September. Those figures are substantially above 1.7%.

The Personal Consumption Expenditures price index, another major inflation gauge, does not provide a better fit. September data was not yet available, but its annual inflation readings were 3.5% in June, 3.4% in July and 3.4% in August.

Trump made a similar claim earlier in the year. In May, he said that inflation had been 1.7% for the three months immediately before the conflict with Iran. That assertion was also unsupported, and no substantiation was provided for it.

The distinction matters because inflation is usually described as the pace at which prices change over a 12-month period. When that rate remains above zero, prices are still increasing, even if they are rising more slowly than they did at an earlier point. Lower inflation does not mean that consumers are automatically paying less than before.

The Biden-Era Comparison Is Also Misleading

Trump’s description of 19% inflation under Biden raises a separate problem. The highest annual CPI inflation rate during Biden’s presidency was 9.1%, reached in June 2022. That was a painful rate for households, but it was not 19%.

Trump has previously suggested that the official 9.1% figure should be doubled. During a 2022 speech, he cited the 9.1% rate before saying he believed the actual number was twice as high. There is no basis for treating the official CPI figure as half of a supposedly “real” rate.

The number 19% may be an attempt to refer to cumulative inflation rather than a single year’s inflation rate. Cumulative inflation measures how much prices rise over an entire period. Over Biden’s four years in office, CPI prices increased by 21.4%, placing 19% in a broadly similar range if the comparison is about the full term rather than any one month or year.

But that framing would still produce an apples-to-oranges comparison. A cumulative price increase over a 48-month presidency cannot meaningfully be placed beside a claim about only three months under Trump. Different time periods can make nearly any comparison appear more favorable or unfavorable depending on the starting point selected.

For the most recent three-month period, CPI prices rose a cumulative 1.1%. That figure does not match Trump’s 1.7% claim either. Through the first 20 months of Trump’s current term, cumulative inflation was 5.4%.

Why the Numbers Matter to Voters

Inflation statistics can be technical, but their practical meaning is straightforward. Annual inflation gauges show whether prices are increasing faster or slower than they were a year earlier. Cumulative inflation shows how much more expensive goods and services have become since a specified starting date.

Both measures can be useful when they are clearly identified and compared over equivalent periods. Problems arise when a short-term figure is presented beside a multiyear total, or when an annual rate is confused with a cumulative price change.

Trump’s statements combine a 1.7% number that does not align with recent CPI or PCE data and a 19% Biden-era figure that does not reflect the peak annual inflation rate. The available records show that inflation remains above the level Trump has claimed, while prices have continued to move upward rather than broadly falling.

For voters weighing economic claims, the key question is not simply whether inflation is lower than at its post-pandemic peak. It is whether the figures being cited describe the same measure, the same time frame and the same real-world experience at the checkout counter. In this case, Trump’s comparison does not meet that test.
