Declarations have been made, but there’s not enough data yet to make such judgements. Andrew Ackerman and Alyssa Fowers report for the Washington Post:
Seven months of data isn’t usually enough to pin down the true direction of inflation, which can be swayed in the short term by one-off events. Applying Trump’s method to other points in the past year shows how far actual annual inflation can stray from an annualized estimate. For example, the 12-month inflation rate in October 2024 was much lower than an annualized estimate based on seven months of data.
A difference chart, shown above, compares actual inflation (over twelve months) against an estimate based on just seven months of data. The estimate and actual are rarely the same, and the range of difference is wide enough to declare defeat, too.
But, as we know, cherrypickers are gonna cherrypick.
