SupplyChainBrain reports; analyst insight; Yemen-based Houthi rebels are threatening to resume attacks on commercial vessels moving through the Red Sea region unless Israel reopens Gaza to international aid. Israel began imposing a full blockade on all aid and supplies to Gaza on March 2—followed the next week by cutting electricity to the region—demanding that Hamas return 24 living Israeli hostages the terrorist group continues to hold since the two sides agreed to a ceasefire in January. On March 7, Yemen-based Houthis issued an ultimatum to Israel: lift the blockade against Gaza by March 11, or the rebel group will resume attacks on vessels in the Red Sea and Gulf of Aden—according to Al Jazeera reporting.
From a supply chain perspective, the Houthi movement (officially Ansar Allah; "Supporters of God"), led by Abdul-Malik al-Houthi, controls the capital Sanaa in north-central Yemen and has been a party to the Yemen civil war since 2014, backed by Iran. From November 2023 through the January 2025 ceasefire, Houthis have attacked 100+ commercial vessels in the Red Sea—using ballistic missiles, unmanned aerial vehicles, naval mines, and USV (unmanned surface vehicles) as primary attack weapons. Galaxy Leader (November 2023; Ray Car Carriers), Tutor (June 2024), Rubymar (March 2024), and True Confidence (March 2024) are among the main vessels sunk or damaged. The impact of the Red Sea crisis has caused Suez Canal traffic to decline approximately 70–80 percent—as container vessels divert to the Cape of Good Hope route—resulting in +10–14 days additional transit time, +1,500 nautical miles of additional distance, and +30–40 percent increased fuel consumption as major impacts. Bab el-Mandeb, the southern entrance to the Red Sea, represents a critical chokepoint.
From a supply chain perspective, Operation Prosperity Guardian (launched December 2023) operates under the umbrella of the Combined Maritime Forces (CMF; Bahrain)—a 20+ nation coalition led by the United States, with major U.S. contributions including the U.S. Navy 5th Fleet, USS Dwight D. Eisenhower, and USS Theodore Roosevelt. EU Operation Aspides (launched February 2024) represents a joint European Union Red Sea defense operation—with France, Germany, Italy, Greece, Belgium, Netherlands, Denmark, and Spain among the main Aspides participants. UK Royal Navy Operation Poseidon Archer represents an additional major coalition operation. Affected major ocean container carriers—Maersk, MSC, CMA CGM, Hapag-Lloyd, ONE, Evergreen, HMM, Yang Ming, Zim—are all avoiding the Red Sea. COSCO Shipping and OOCL (COSCO subsidiary) are partially exempted by the Houthis—being China-flagged and -owned vessels.
From a supply chain perspective, the Suez Canal Authority (SCA; Osama Rabie, Chairman; Ismailia, Egypt) saw fiscal year 2023 revenues of 9.4 billion dollars decline to approximately 5 billion dollars in fiscal year 2024—representing approximately 50 percent revenue loss as a result of the Houthi crisis as a major economic impact. The Egyptian General Authority for Maritime Safety (EGAMS) is Egypt's primary maritime security authority. BIMCO (Baltic and International Maritime Council; Copenhagen) and the International Chamber of Shipping (ICS) are major global maritime shipping sector advocacy groups. The Joint War Committee (Lloyd's market) lists the Red Sea as a high-risk war zone—with additional war risk insurance premiums reaching 0.7–1.0 percent of vessel value. Drewry World Container Index, Freightos Baltic Index (FBX), and Xeneta XSI are major container freight rate tracking indices—experiencing 200–300 percent spikes during the Red Sea crisis. As a result, renewed Houthi threats appear to be fundamentally reshaping global Red Sea capacity strategy—making Cape route planning and war risk insurance major strategic priorities for supply chain managers.
Key Points:
1. Houthis are threatening to resume attacks unless the blockade on Gaza is lifted.
2. 100+ commercial vessels were attacked between November 2023 and January 2025.
3. Suez traffic has declined 70–80 percent; Cape route adds +10–14 days additional transit.
4. Operation Prosperity Guardian and EU Aspides are major coalition operations.
5. SCA is experiencing approximately 50 percent revenue loss due to the Houthi crisis.
