An estimated 12% of global trade worth more than $1 trillion traverses the Red Sea each year. When Houthi rebels started attacking commercial vessels in November 2023, ocean carriers began rerouting container ships around Africa’s Cape of Good Horn rather than through the Suez Canal on voyages from Asia to Europe. That greatly increased travel time and costs. As of March of this year, shipping through the Red Sea was still down 70% from before the attacks began, according to The Economist, with many ocean carriers still avoiding the Bab el-Mandeb Strait, which separates the Red Sea from the Gulf of Aden and the Arabian Peninsula. Maritime Industry Caught in the Crosshairs Houthi rebels launched attacks on ships in the Red Sea in response to Israel’s military operations in Gaza.
