PoI Dossier

Strait of Hormuz

Analyst-facing Hormuz dossier updated to the 4 April 2026 crisis picture, combining the new follow-on research narrative with current local mosaic context for the most consequential Gulf shipping chokepoint.

Overview

Sustained throughput collapse with global spillover

The April 4 update treats Hormuz as a crisis-constrained corridor rather than a merely stressed one. The main analytic question is how long severe suppression of commercial traffic persists and whether safe-passage efforts can restore usable throughput before wider energy, fertilizer, and shipping effects deepen.

Current Posture

Commercial functionality remains severely impaired

  • JMIC's 16 March advisory reported only three observed commercial cargo transits per day versus about 138/day historical traffic.
  • UNCTAD's 30 March update said shipping through Hormuz had collapsed by over 95%.
Use First

Anchor on baseline exposure, then on crisis-state suppression

  • Start with the EIA throughput and bypass-capacity figures to frame structural importance.
  • Then use the JMIC, IMO, MARAD, and UNCTAD claims matrix to interpret current operating conditions.

Supporting Visual Context

Current monthly Sentinel mosaics from the Iran events run provide route geometry context while the follow-on research captures the updated crisis assessment.

Latest Optical Context

Sentinel-2 Monthly Mosaic

Direct Sentinel Hub optical mosaic for the 5 March 2026 to 3 April 2026 window over a widened 50 km AOI. This provides coastline and island context instead of a central-water-only crop.

  • Quality: good, valid pixel ratio 0.999
  • Use: visual route, island, and shoreline context

Approach Traffic

Sentinel-1 Approach Zooms

Targeted radar zooms from the same monthly Sentinel-1 mosaic make the approach pattern easier to read than the full AOI view. Bright returns in these waters are consistent with vessels waiting or moving slowly in the approach area, rather than open-water background texture.

  • Window: 2026-03-05 to 2026-04-03
  • Source: cropped from the regenerated Sentinel-1 monthly mosaic
  • Use: visualize likely waiting traffic in the eastern and Omani-side approaches
