Houthi activity in the Bab el-Mandeb strait has cut Red Sea tanker traffic to a multi‑month low, raising freight costs and oil‑market uncertainty
Executive summary: Red Sea tanker traffic fell to its lowest level in several months after Houthi forces renewed missile and drone threats against vessels transiting the Bab el‑Mandeb strait. The slowdown forces oil exporters to take longer routes, increasing shipping costs, insurance premiums and potentially lifting global crude prices.
Who is involved: Houthi rebels, Saudi Aramco and other Middle‑East crude exporters, international shipping companies, Egypt’s Sidi Kerir terminal, and naval forces engaged in maritime security.
Likely next: Continued rerouting of crude shipments, possible expansion of naval escort missions, and a rise in freight and insurance costs unless the security situation improves.
More than a dozen empty supertankers are currently headed to Egypt’s Sidi Kerir port to load Saudi crude terminal as Saudi Arabia reroutes its crude exports to avoid Houthi‑launched missiles and drones. The decline in vessel transits through the chokepoint reflects the group’s continued ability to threaten commercial shipping despite international naval patrols. The disruption is prompting shippers’ detour adds voyage length and fuel burn, which will likely feed into higher spot freight rates and upward pressure on crude prices.
