Houthi Threats Prompt Red Sea Tanker Rerouting

Background and Context
In early July 2024, Yemen’s Iran-aligned Houthi militia announced a naval blockade against Saudi Arabia, citing solidarity with Palestinians in the Gaza conflict. The group has previously targeted merchant vessels off Yemen’s coast, a campaign that intensified after the Gaza ceasefire in October 2023. The new blockade warning marks a shift toward threatening ships that load or discharge cargo at Saudi ports, raising concerns for global energy supplies that rely on Red Sea routes.
Ship Movements and Economic Impact
On July 22, ship-tracking data showed five tankers altering their courses in the Red Sea. Two of these vessels signaled a change of destination to the Suez Canal rather than proceeding south toward the Bab el-Mandeb strait. A sixth vessel, the vehicle carrier Liu Jiang Kou, turned away in the Gulf of Aden after indicating Jeddah as its next port. The product tanker Philoxenia and the tanker Alexandros both dropped anchor near the Suez Canal while still listed for loading at Yanbu.
Earlier in the week, three oil tankers carrying Saudi crude for China and India made U-turns in the Red Sea and headed toward the Suez Canal. One of these, the Xin Long Yang, is managed by COSCO Shipping. Ship broker Clarksons noted that the Houthi threat is beginning to affect overall tanker activity, while broker Braemar warned that the embargo raises serious questions about the viability of eastbound routes from Yanbu, the outlet for Saudi Arabia’s east-west pipeline. Rerouting cargoes via the Suez Canal adds roughly 10,000 nautical miles and an extra 34 days of sailing, translating to estimated freight cost increases of more than $5 million per vessel, plus about $1 million in Suez transit fees.
Official Advisories and Responses
The European Union’s Aspides naval force issued an advisory urging ships linked to Israel, the United States, or Saudi Arabia to avoid Red Sea and Gulf of Aden voyages until the threat level declines. The advisory also recommended that vessels recently calling at Saudi ports reduce their electronic footprint by limiting AIS transmissions and other publicly accessible data. Greece’s shipping ministry echoed the warning, urging its fleet to coordinate with the Aspides mission amid heightened risks. COSCO Shipping, the manager of Liu Jiang Kou, did not respond to Reuters’ request for comment, and managers of the Philoxenia and Alexandros were similarly unavailable.
Implications for Global Trade
A potential closure of the Red Sea’s southern gateway would eliminate a critical alternative to the Strait of Hormuz for Saudi oil exports, intensifying fears of supply shortages. The added distance and cost of rerouting through the Suez Canal could raise oil prices for Asian buyers and strain shipping schedules. Maritime security sources reported receiving additional Houthi warnings to vessels in the Red Sea, underscoring the ongoing risk to commercial navigation in the region.
