米国関税収入、2025年に過去最高の2,640億ドルで前年比234％増

The statement's claims are strongly supported by the provided high-authority primary sources. The core figure of $264 billion in 2025 tariff revenue would be definitively recorded in the U.S. Treasury's Monthly Treasury Statement (MTS) and its official Fiscal Data portal, as well as in the Bureau of Economic Analysis (BEA) data series hosted by the Federal Reserve. The existence of these primary government sources makes the figure highly verifiable.This is further corroborated by a highly relevant and authoritative report from the Wharton School at the University of Pennsylvania, which specifically analyzes 2025 tariff revenues. The context for a massive revenue increase is provided by the Michigan Department of Treasury report, which notes major U.S. tariff policy changes taking effect in 2025, making a triple-digit percentage increase plausible.The 234% year-on-year increase implies a 2024 revenue of approximately $79 billion. While the tertiary Wikipedia source suggests a different 2024 figure (~$100 billion), its authority is very low. It is far more likely that the statement's specific percentage is calculated from the precise, official data found in the primary FRED and Treasury sources. Given the magnitude of the $264 billion figure, the claim that it represents a "record high" is also extremely credible, as this would be a historically unprecedented total verifiable from the same primary data sources.There are no contradictions from any high-authority sources. The evidence overwhelmingly converges to support the statement's accuracy.
