In late March local time, Yemen's Houthi forces launched missiles at southern Israel, marking their formal entry into the core of the regional conflict. This long-standing Iran-backed faction broke its previous cautious stance, viewed as a key strategic signal from Tehran. With the Red Sea lanes facing new blockade risks, global energy supply networks are undergoing an unprecedented stress test.
The Houthis had previously established clear red lines, including military operations against Iran utilizing the Red Sea, the formation of a new anti-Iran coalition, and continued expansion of regional military escalation. Once these conditions were met, the group acted swiftly. While Israeli forces intercepted some threats, air raid sirens sounded in towns like Beersheba, indicating that conflict spillover has directly impacted Israel's interior. Analysts suggest that if the Bab el-Mandeb Strait once again becomes a focal point, tensions in the Strait of Hormuz will compound, delivering a dual blow to international oil and gas transportation.
As a critical chokepoint linking the Indian Ocean and the Mediterranean, the strait handles over four million barrels of oil daily, accounting for between 12% and 20% of global maritime oil trade. Should this channel be blocked, alternative routes relying on Saudi Arabia's east-to-west pipelines exporting through the Port of Yanbu would also be paralyzed. Markets currently worry that forcing tankers to reroute around the Cape of Good Hope will extend voyages by over ten days and double freight costs. Since the beginning of last year, Red Sea shipping volumes have plummeted by 70%, with Suez Canal traffic sharply declining. Should the situation escalate to a full blockade, the impact could surpass all previous records.
The economic chain reactions are equally significant. The surge in shipping costs is expected to result in a loss equivalent to 0.5% to 1.3% of global GDP. Meanwhile, the US government's stance on the Middle East situation has shown volatility, shifting from initial threats to strike Iranian power stations to postponing action and seeking dialogue. Internally, there are even rumors considering ground operations to seize Kharg Island. The Iranian military has issued warnings, emphasizing that reckless US actions to resolve navigation issues could lead to further complications in surrounding waters.
Currently, Saudi Arabia, Israel, and the US are attempting to contain the scope of the conflict to prevent deep Houthi involvement, but Iran's gradually escalating strategic layout appears to have already played this card. The flames of war in the Middle East are spreading from the Persian Gulf to the Red Sea. The rising risk of regional conflict not only tests the balance of geopolitics but also directly impacts the stability of global supply chains and energy market expectations.
