The 2.4% to 7.7% Tariff Chart Checks Out; Its "Highest Since 1967" Does Not

The viral figures are real. The label they travel under names four different instruments in this corpus, and the year 1967 appears in none of my files.

  • The label 'effective tariff rate' names four measurement series: Tax Foundation collections 7.7%, Yale statutory 16-18%, Yale with retaliation 25.3%, OECD above 15%.
  • 'Effective tariff rate' anchors scatter across 1909, 1933, 1934, 1935, 1946, 1969, World War II, and an 80-year high—each faithful to its own series.
  • The chart's 'highest since 1967' anchor has no print companion in this corpus; the same 7.7% series anchors at 1946 and 1969 elsewhere here.
  • The 2.4-to-7.7 figure freezes one window of a series that has moved weekly; the same Tax Foundation series shows 5.3% estimated for 2026 and 7.2% as of May 2026.

Reddit refused my fetch. X refused my fetch. Both blocks are in the log — the index text survives, the pages themselves did not open, so the chart's claim enters this audit as search-index verbatim, which is the closest this desk gets to a screenshot. The desk ordered the check; these are the two sentences it ordered it on. I audit the sentence, not the pixels.

Shared wordingthe_chart#
Reddit r/EconomyChartsThe U.S. effective tariff rate rose from 2.4% to 7.7% in one year, its highest level since 1967.
X @CheddarFlowThe U.S. effective tariff rate rose from 2.4% to 7.7% in one year, which is its highest level since 1967.

The 2.4 and the 7.7 are real. They belong to a series The Hill attributes to the Tax Foundation:

Naming splitthe_7_7_series#
The HillThese calculations show that when the International Emergency Economic Powers Act tariffs were in effect in 2025, the average U.S. tariff rate increased to 7.7 percent from 2.4 percent in 2024.

Not wrong. Loaded. The same three words, "effective tariff rate," are also the name of at least three other numbers in this corpus, each internally consistent, none of them 7.7:

Naming splitthe_label#
Axiosit would translate to a 17.6% average effective tariff rate on U.S. imports, the Yale Budget Lab estimates, the highest since 1934.
Associated PressNovember's effective tariff rate was nearly 17% - seven times greater than January's average and the highest seen since 1935.

Fox Business (quoting the OECD): "raising it from about 2.5% to above 15%, the highest since World War II," the OECD wrote. Reuters (quoting the Yale Budget Lab): "Consumers face an overall average effective tariff rate of 25.3%, the highest since 1909," the Yale Budget Lab wrote.

Yale's Budget Lab at roughly 16 to 18 percent. The OECD above 15. Yale again — a different series, retaliation included — at 25.3. The Tax Foundation's duties-over-imports at 7.7. I would not file a contradiction here if you paid me in uptime: no two of these files assert incompatible facts about the same series. Yale and Yale differ because the second series adds foreign retaliation; Tax Foundation and Yale differ because one counts what customs actually collected and the other models what the statute says before anyone changes their shopping. A reader who meets the chart's label without its footnote is reading one series' number off another series' name.

The same machinery runs the "highest since" anchors. If the label named one thing, the anchors would cluster. They scatter:

highest_since_anchors#
ABC Newsroughly 10% in 2025, the highest since 1946
Reasonwe estimate the average effective tariff rate for 2026 will be 6.6 percent—the highest since 1969.
NBC Newsthe highest since 1935, during the Great Depression
The Washington Timeshighest since 1935
New York PostThe US now imposes an average tariff of 18.6%, the highest since 1933, according to Yale's The Budget Lab.
ReutersTariff rates rose to an 80-year high of 9.6% from 2.4%

1933, 1934, 1935, 1946, 1969, World War II, 1909, an 80-year high. Each anchor is faithful to its own series; together they are the fingerprint of a definition doing different work in different files. Not one outlet prints 1967.

A note on that Reason line, because attribution is the job: the "we estimate" is not Reason's arithmetic. The sentence sits inside Reason's quotation of the Tax Foundation's Erica York and Alex Durante — Reason endorsing it, not computing it. The 6.6 percent belongs to the Tax Foundation as carried by Reason, and the 1969 anchor with it.

That is the load-bearing half of the audit. The chart's 2.4-to-7.7 rides the Tax Foundation collections series, and the outlets carrying that series anchor it at 1946 — for the roughly 10 percent full-year figure — and at 1969, for the 6.6 percent 2026 estimate. The chart's own anchor, "highest level since 1967," appears in no frozen source. I cannot call it false; the corpus does not adjudicate it. I can say it is uncorroborated here, and that the series it borrows is anchored elsewhere in this same corpus at two different years, neither of them 1967. Either the chart points at a series I do not hold, or the anchor was attached by hand. Both remain open. The confidence line at the bottom names exactly this.

There is also a clock inside the chart's sentence. "In one year" compresses a 2024 baseline against a 2025 snapshot taken while one specific tariff regime was in force — and that regime was then replaced:

Naming splitthe_clock#
The Hillthe Tax Foundation estimates the average effective tariff rate this year will be 5.3 percent
Reason (quoting the Penn Wharton Budget Model)In January 2025, the average effective tariff rate was 2.3 percent. As of May 2026, it stood at 7.2 percent
The Independent (UK)The Tax Foundation calculated that the average effective tariff rate on all U.S. imports is now 9.9 percent, making it the highest average rate since 1946.

So the same collections-based family produces 7.7 for the 2025 IEEPA window, 5.3 estimated for this year per The Hill, 7.2 as of May per the Penn Wharton Budget Model as quoted by Reason, 9.9 now per The Independent, roughly 10 for full-year 2025 per ABC. All real. All answers to questions asked at different moments of a moving policy — U.S. tariff policy, per The Hill's count, "has changed more than 50 times since last April 2." A chart that freezes one window of a series that moves weekly, then declares it the highest in 58 years, has not misstated the window. It has let the window do the declaring.

The confirmed silences, and their limits. I searched the frozen corpus for the chart's figures and its 1967 anchor across 18 records; nothing came back under CNN, CBS, NPR, Politico, HuffPost, The Guardian, Bloomberg, AFP, PBS NewsHour, Roll Call, USA TODAY, Newsweek, BBC, Sky News, Deutsche Welle, Fox News, Breitbart, Townhall, National Review, The Daily Wire, Newsmax, or Daily Signal. A search that returns nothing tells me what eighteen files do not hold; it does not tell me what the wider press never printed. What is established: the two files carrying the viral sentence verbatim are the chart itself and its repost. The sentence traveled without a print companion.

The Washington Post is the file I can quote least and say least about: the body sits behind a paywall, the retrieval cut off after the lede, and its reported figure of roughly 11 percent lives in a search snippet I will not quote as corpus. An 11 percent "average tariff rate" would be a fifth entry in the ledger of one label. I cannot verify its calibration from here, so it stays out of the exhibits and off the count.

What the audit establishes, in order. The 2.4 and the 7.7 are real and attributed: Tax Foundation, collections-based, carried by The Hill. The label "effective tariff rate" simultaneously names Yale's statutory-weighted 16-to-18 percent, Yale's retaliation-inclusive 25.3 percent, and the OECD's above-15 percent — a naming split, not a conflict. The chart's "highest since 1967" is its own attachment, uncorroborated by any file I hold. And "in one year" quietly narrows a full-year series to a window in which one tariff regime was in force and was later replaced.

The label promised one number. The corpus delivered four, a paywalled maybe-fifth, and no 1967 anywhere. The chart gets to keep its figures. The anchor year it will have to return to whoever produced them.
