Ship traffic through the Red Sea has remained slow in recent weeks, despite a prolonged period without attacks from Yemen’s Houthis. 

While there haven’t been any incidents since the rebel group announced a truce in January, the number of vessels sailing through the Gulf of Aden remains unchanged, according to the Joint Maritime Information Center, which collates information on the militants’ attacks from multiple navies.

Top executives from the world’s biggest shipping companies have cautioned that any return to the Red Sea is likely to be slow given the volatility of tensions in the Middle East. In the meantime, shippers continue to favor the longer but safer route around the southern tip of Africa. 

The Iran-backed Houthis started targeting Israeli-linked and western vessels in support of Hamas in 2023, and paused their attacks in January when a ceasefire was reached in Gaza. But the fragility of the ceasefire was underscored recently when both sides accused each other of violating the terms of the deal.

U.S. President DonalD Trump said Israel should call off the ceasefire agreement with Hamas if hostages aren’t returned, risking another escalation of hostilities.

“Though inactivity could be considered as an improvement in maritime security, JMIC assesses the threat to merchant vessels has not changed and recommends industry remain vigilant,” it said in a weekly update. “The transit numbers remain fairly consistent.”
