Source Overview

The IEA's April 2026 Oil Market Report is the premier institutional assessment of the global oil supply shock triggered by the US-Israel conflict with Iran and the resulting near-total closure of the Strait of Hormuz. It is the most authoritative and widely cited public document on the scale and mechanics of the disruption.

Key Claims & Data Points

• Largest supply disruption in history: The IEA characterised the conflict-driven Hormuz closure as "the largest supply disruption in the history of the global oil market."
• Hormuz loadings collapsed: In early April, shipments through the Strait averaged ~3.8 mb/d (crude, NGLs and refined products combined), compared with >20 mb/d in February before the crisis.
• Cumulative supply losses: >360 million barrels (mb) lost in March; 440 mb projected for April.
• Overall export loss >13 mb/d: Combined effect of Hormuz closure plus infrastructure damage.
• Alternative routing partially offset: West-coast Saudi Arabia, Fujairah (UAE), and the Iraq–Türkiye ITP pipeline rose to 7.2 mb/d from <4 mb/d pre-war.
• Global stock draws: Observed oil stocks fell 85 mb in March despite builds in the Middle East and China.
• Demand destruction: Global oil demand contracted 800 kb/d YoY in March and an estimated 2.3 mb/d in April — the sharpest monthly decline since COVID-19. Full-year 2026 forecast flipped from +730 kb/d growth to -80 kb/d contraction.
• Physical-futures disconnect: Physical crude (Dated Brent) surged to ~$150/bbl — far above futures — reflecting acute regional scarcity. Middle distillates in Singapore hit all-time highs above $290/bbl.
• Ceasefire uncertainty: The report's base case assumes a resumption of regular Middle East flows "by mid-year, although not back to pre-conflict levels." An alternative scenario (Strait Down) models a prolonged high-disruption outcome.

Source Quality

Institutional primary source — HIGHLY CREDIBLE. IEA is an intergovernmental organization with 32 member countries, producing the most comprehensive public oil market dataset. The April 2026 report was published mid-crisis (April 14) and reflects live data. The physical/futures disconnect ($150 physical vs ~$99 futures) is an important market structure observation.

Relevance to Q1/Q2/Q3

• Q1-SUPPLY-DESTRUCTION: Core source. IEA directly quantifies the March supply destruction (360 mb lost) and documents the mechanism (Hormuz closure + infrastructure attacks). Supports Q1 supply loss estimates.
• Q2-PRICE-IMPACT: Core source. Documents the physical crude spike to $150, distillate markets in extremis, and IEA's reversal from growth to contraction forecast — key inputs for the Q2 price impact analysis.
• Q3-EUROPE-IMPACT: The IEA notes jet fuel demand destruction from flight cancellations across Europe, linking Q2 supply shock to emerging Q3 demand-side consequences for Europe.

Notes

• The free PDF version (hosted at iea.blob.core.windows.net) was confirmed accessible in search results with data on the 14.2 mb/d Hormuz crude/condensate collapse (from Kpler data).
• The $150/bbl physical vs ~$99 futures disconnect is a distinctive and important data point for the KB's Q2 price narrative.
