Key Facts

Houthi Preparations and Embargo Declaration

  • Joint Maritime Information Center (JMIC) advisory (Jul 21): "Sources close to the group stated that the Houthis have completed preparations to attack shipping, including the deployment of missiles and drones positioned near Bab el-Mandeb"
  • JMIC headquartered in Bahrain, provides security updates to commercial ships in the Middle East
  • EU naval mission Aspides (Jul 22): warned that "merchant vessels linked to Israeli, U.S. or Saudi interests" should "avoid transiting the Red Sea and Gulf of Aden until the threat level decreases"
  • Houthis declared a maritime embargo against Saudi Arabia on Monday Jul 20 — threatening to cut off kingdom's oil exports through Red Sea and Bab al-Mandeb
  • Houthis: "all vessels loading or discharging cargo at or from any Saudi ports are prohibited" (per EU naval mission notice)

Yanbu Throughput: Pre-Embargo Context

  • Kpler data: Exports from Yanbu through Bab al-Mandab surged to 3.5 million barrels per day in June (2026)
  • vs just 240,000 bpd in the same period last year (June 2025)
  • = 14.6× year-over-year ramp
  • This is the canonical pre-event Yanbu flow figure that the east-west-pipeline concept references

Day-One Traffic Impact (Jul 20-21)

  • Kpler (Jul 21): "34% decline in traffic through the Bab el-Mandeb on Tuesday compared with Monday, when the Houthis declared the embargo against the Saudis"
  • Windward data: "Four tankers with Saudi cargo turned around before reaching Bab al-Mandeb on Tuesday" — ships carrying "3.8 million barrels of crude oil, gasoil and naphtha"

Mixed Signal: Commercial Routes (per JMIC)

  • JMIC (Jul 21): "No changes to commercial routing or transit patterns occurred, and vessels continued to use established lanes without disruption" — threat level "moderate"
  • This contradicts the Kpler 34% decline — likely JMIC is reporting routing decisions (lane choice) vs Kpler reporting actual transit counts

Hormuz Context (Concurrent Escalation)

  • Iran "stepped up its attacks on tankers in Hormuz as it tries to force vessels to transit the strait through its territorial waters"
  • 3 crude oil, products and chemical tankers attacked off Oman/UAE "this week"
  • IMO counts: "A dozen ships attacked in and around Hormuz since July 6" — 2 seafarer deaths, 12+ injuries

Significance for the KB

  1. Embargo declaration date = Jul 20, 2026. This CNBC article fixes the Houthi maritime embargo against Saudi Arabia to Monday Jul 20, 2026. Cross-references 2026-07-27-the-hill-houthis-saudi-oil-depots (blockade imposed "last week" before Jul 27 = week of Jul 20).
  2. Yanbu ramp quantified: 14.6×. 240 kbpd (Jun 2025) → 3.5 mb/d (Jun 2026) = 14.6× year-over-year Yanbu/Bab al-Mandab flow ramp. This is the single most important pre-event Yanbu throughput number in the KB.
  3. Day-1 traffic drop = 34%. Kpler day-over-day decline establishes the immediate elasticity of Bab al-Mandab traffic to Houthi embargo declaration. Use as a reference for subsequent escalation effects.
  4. 3.8 mn bbl stranded at sea. Windward reports 4 Saudi cargo tankers turned around carrying 3.8 mn bbl crude/gasoil/naphtha. This is the physical supply disruption number that hits the global diesel/crude markets on Day 1.
  5. JMIC vs Kpler conflict. JMIC says "no changes to commercial routing"; Kpler says -34% traffic. These are not contradictory but measure different things — JMIC = routing decisions of ships in the area, Kpler = aggregate traffic counts. The KB should note both.
  6. Aspides (EU naval mission) warning. First formal EU naval advisory tying Saudi-flagged vessels to transit avoidance — institutional policy response to the embargo.

Ingested 2026-09-16 from cnbc.com. Direct fetch succeeded; full body captured. Yanbu 14.6× YoY throughput ramp (240 kbpd → 3.5 mb/d Jun 2025→Jun 2026) is the canonical pre-event data point for the east-west-pipeline concept.
