Summary overview

This Financial Times article examines how the US-Iran conflict drove an energy-led inflation surge in early 2026, and the core narrative holds up well — but several specific figures are wrong in ways that matter. The headline CPI reading of 3.3 percent for March 2026 and the core inflation figure of 2.6 percent are both confirmed by Bureau of Labor Statistics data. The most significant errors involve oil prices and forecasts: Brent crude peaked at roughly $119.56 a barrel, not the 'more than $110' stated — the article actually understates how high prices went. The OECD's US inflation forecast was raised from 3.0 percent (not 2.8 percent as claimed) to 4.2 percent — the 2.8 percent figure was the prior forecast for the G20 aggregate, not the US. The IMF's pre-war US inflation forecast was 2.4 percent, not 2.5 percent. The post-ceasefire oil price drop is also described incorrectly: prices did not fall below $90 a barrel. The diesel price trajectory cited ($3.76 to $5.59) does not match EIA data, which shows the move was from $3.81 to $5.61.

What we reviewed

Verification drew on 377 successfully retrieved sources from 391 attempted URLs, spanning primary statistical agencies including the Bureau of Labor Statistics, the Energy Information Administration via FRED (St. Louis Fed), the IMF World Economic Outlook DataMapper, the OECD Economic Outlook, and the University of Michigan Surveys of Consumers. Most key numerical claims were checked directly against machine-readable primary source data. The main gap was the specific AAA gasoline price on April 17, 2026 ($4.08 per gallon), where available evidence confirmed the starting price but could not verify the endpoint figure from a primary source on that exact date.

Article excerpt

…The University of Michigan’s consumer sentiment index fell to a record low in April amid gloom over rising prices.…

Analysis

The University of Michigan's preliminary April 2026 survey showed a sentiment reading of 49.8, and multiple sources including Bloomberg Law and CNBC reported this as a record low. The final reading came in at 47.6, reinforcing the record-low characterization. Confidence is medium because the FRED series had not yet been updated with the April figure at the time of retrieval. University of Michigan Surveys of Consumers

Article excerpt

Brent crude was around $70 a barrel when the conflict began

Analysis

FRED data for Brent crude (DCOILBRENTEU) shows a price of $71.32 per barrel on February 27, 2026, consistent with the article's 'around $70' characterization at the conflict's outset. The figure is within normal rounding tolerance of the claim. FRED DCOILBRENTEU

Article excerpt

Brent crude reached more than $110 a barrel at its height

Analysis

FRED data for Brent crude shows the price reached $119.56 per barrel on April 1, 2026 — well above the 'more than $110' stated in the article. The article understates the peak rather than overstates it, but the specific figure of $110 as the ceiling is contradicted by the primary data. FRED DCOILBRENTEU

Article excerpt

US inflation jumped to 3.3 per cent in March

Analysis

BLS data for the CPI-U All Items series shows a 12-month percent change of exactly 3.3 percent for March 2026, directly matching the article's figure. This is one of the most straightforwardly verified claims in the piece. Bureau of Labor Statistics

Article excerpt

March 2026 inflation was at its highest level in two years

Analysis

BLS data shows the 12-month CPI change was 3.5 percent in March 2024 and 3.4 percent in April 2024 — both higher than the 3.3 percent recorded in March 2026. Because higher readings occurred within the two-year window, March 2026 was not the highest inflation reading in two years. The article's framing on this point is incorrect. Bureau of Labor Statistics

Article excerpt

The IMF estimates US inflation of 3.2 per cent for 2026

Analysis

The IMF World Economic Outlook DataMapper explicitly lists the 2026 US inflation forecast (average consumer prices, percent change) as 3.2 percent, matching the article's figure exactly. IMF World Economic Outlook DataMapper

Article excerpt

IMF's pre-war US inflation forecast was 2.5 per cent

Analysis

The January 2026 IMF World Economic Outlook Update — the most recent edition before the conflict began in late February 2026 — explicitly states the assumed US inflation rate for 2026 was 2.4 percent, not 2.5 percent. The article overstates the pre-war baseline by 0.1 percentage points, which affects the implied magnitude of the upward revision. IMF WEO Update January 2026

Article excerpt

Core inflation edged up to 2.6 per cent in March versus the previous year

Analysis

BLS data for the CPI-U All Items Less Food and Energy series shows a 12-month change of exactly 2.6 percent for March 2026, matching the article's figure precisely. This confirms that while headline inflation surged on energy, underlying price pressures remained relatively contained. Bureau of Labor Statistics

Article excerpt

…The OECD has increased its forecasts from 2.8 per cent to 4.2 per cent.…

Analysis

The OECD's March 2026 Interim Economic Outlook raised the US inflation forecast to 4.2 percent — confirmed — but the previous US-specific forecast was 3.0 percent, not 2.8 percent. The 2.8 percent figure was the prior forecast for the G20 aggregate, which was revised up to 4.0 percent. The article mixes the G20 baseline with the US updated figure, making the stated starting point incorrect. OECD Economic Outlook Interim Report March 2026

Article excerpt

…Petrol prices have surged from $2.98/gallon when the conflict began to $4.08 on Friday, according to the AAA motoring group.…

Analysis

Available evidence confirms the AAA national average gasoline price was approximately $2.98 per gallon in late February 2026, consistent with the article's starting figure. However, no primary source data for April 17, 2026 (the Friday in question) was accessible to verify the $4.08 endpoint. AAA daily price data for that specific date would be needed to confirm or contradict the claim. (eia.gov)

Article excerpt

…Diesel — which is a key input in everything from agriculture to trucking — has jumped from $3.76 to $5.59 a gallon since the conflict erupted.…

Analysis

EIA data via FRED (GASDESW) shows US diesel was $3.809 per gallon on February 23, 2026, and $5.608 per gallon on April 13, 2026 — close to but not matching the article's figures of $3.76 and $5.59. The $5.59 figure appears to come from a private fleet index (Samsara), not the official EIA benchmark. The direction and rough magnitude of the move are right, but the specific numbers cited do not match the primary government data series. FRED GASDESW

Article excerpt

…That leaves it close to the $5.82 record it hit in 2022 in the wake of Russia’s full-scale invasion of Ukraine.…

Analysis

EIA historical data and contemporaneous reporting confirm that US diesel prices reached record highs in 2022 following Russia's full-scale invasion of Ukraine, with the peak consistent with the $5.82 figure cited. The adjudication found the observed value within tolerance of the claim, though confidence is medium given the reliance on secondary corroboration alongside the primary EIA series. FRED GASDESW

Article excerpt

…Its index of inflation expectations showed Americans anticipated prices rising 4.8 per cent over the next year, up from 3.8 per cent a month ago.…

Analysis

FRED data for the Michigan inflation expectations series (MICH) shows the March 2026 reading was 3.8 percent, consistent with the article's 'a month ago' figure. The April 2026 preliminary reading of 4.8 percent is corroborated by multiple secondary sources reporting the final figure. The 3.8-to-4.8 percent move is supported by the available data. FRED MICH

Article excerpt

Crude prices dropped more than 10% to below $90/barrel after Tehran's Hormuz announcement

Analysis

FRED data for WTI crude (DCOILWTICO) shows a price of $109.76 per barrel as of early May 2026, well above the sub-$90 level the article describes following the ceasefire announcement. While oil prices did fall sharply after Iran declared the Strait of Hormuz open, the available primary data does not support prices having dropped below $90 a barrel. FRED DCOILWTICO

Article excerpt

Nitrogen fertiliser costs rose more than 30 per cent since the conflict erupted, per Farm Bureau

Analysis

The American Farm Bureau Federation's own survey and reporting, cited as the article's source, supports the claim that nitrogen fertilizer costs rose more than 30 percent since the conflict began. The adjudication found the lower bound of the evidence consistent with the lower bound of the claim. No contradicting primary data was identified, though the Farm Bureau is the originating source rather than an independent verifier. American Farm Bureau Federation
