Red Sea Crisis: How Houthi Attacks Threaten Global Trade and Regional Stability

The Red Sea, a crucial sea route with approximately 12 percent of world commerce and nearly 30 percent of container traffic, is now a geopolitical hot spot. The recent missile strike of the Scarlet Ray, an Israeli-owned oil tanker, by the Houthi rebels of Yemen demonstrates the way a local insurgency has now influenced international shipping, oil markets, and security in the region in ways few would have thought possible just a year ago.

The Houthis allegedly supported by Iran started as a rebellious group in the north of Yemen in the early 2000s. They engaged in wars against the government of Yemen over the years, opposed a coalition led by Saudi Arabia and finally seized control of Sanaa, the capital of Yemen. However, since November 2023, they have extended their fighting ground.

Following the Israeli airstrikes that killed Houthi Prime Minister Ahmed al-Rahawi and senior ministers last week, the group announced retaliation, and shifted its missiles and drones to Israeli-linked shipping over the Red Sea and Gulf of Aden. To the Houthis, such attacks are a promise of support to Palestinians in Gaza. To Iran, they provide a cheap means to harass Israel and the west without having to face them face-to-face, a typical proxy warfare tactic.
The economic impact has been immediate and severe. Insurance premiums for ships passing through the Red Sea have more than tripled, rising from 0.3 percent of a vessel’s value to over 1 percent since the first attacks, according to Reuters. The Port of Eilat, Israel’s southern gateway, has seen activity collapse by 90 percent since October 2023, losing about $1.2 million every month, reports the Washington Post. Some shipping companies now reroute vessels around Africa’s Cape of Good Hope, adding 10 to 14 extra days to delivery times and raising freight costs by as much as 60 percent. Global oil prices spiked five percent in a single week after the Houthis sank the Eternity C tanker in July 2025, underlining how fragile energy markets have become.

This is why the Red Sea matters far beyond the Middle East. Nearly $1 trillion worth of goods passes through these waters annually, including 6.2 million barrels of oil per day, eight percent of the world’s liquefied natural gas shipments, and a third of Asia-Europe container traffic. Any prolonged disruption risks a repeat of the 1980s Iran-Iraq “Tanker War,” when attacks on shipping sent global markets into turmoil and forced navies to escort commercial vessels across contested waters.

Naval coalitions have already stepped in. The U.S. launched Operation Prosperity Guardian in late 2023, while the European Union deployed Operation Aspides to protect merchant vessels. Yet Lloyd’s List Intelligence reports that by October 2024, over 190 incidents had already taken place in the Red Sea and Gulf of Aden despite these efforts. Saudi Arabia, Egypt, and Gulf states face a difficult balance: they depend on secure trade routes but wish to avoid escalating tensions with Iran or being drawn deeper into regional conflicts.

Looking ahead, four scenarios seem possible. First, the conflict could escalate further if Israeli airstrikes on Yemen intensify, with Houthis expanding attacks into the Arabian Sea and even threatening Indian Ocean shipping. Second, prolonged instability may push companies to develop alternative trade corridors—rail links across the Gulf or even the Northern Sea Route along Russia’s Arctic coast. Third, a diplomatic breakthrough could link a Gaza ceasefire to maritime security guarantees, requiring U.S.-Iran dialogue and regional cooperation. Finally, the Red Sea could become a long-term militarized zone, with constant naval patrols, higher shipping costs, and permanent strategic tensions.

For Israel, this crisis opens a dangerous new southern front. Already facing Hezbollah in Lebanon and militants in Gaza, Israel now must defend shipping routes against Houthis capable of firing missiles over 1,000 kilometers. Iran, meanwhile, benefits from keeping Israel under pressure on multiple fronts without committing its own forces—a strategy that stretches Israeli defenses and complicates Western security planning.

The Scarlet Ray incident may not have caused physical damage, but it delivered a clear message: the Red Sea is no longer just a maritime highway; it has become a frontline in a broader regional conflict. Unless there is coordinated international diplomacy addressing the Gaza war, Yemen’s civil strife, and Iran-Israel tensions, global trade will remain at risk. The world economy, already under strain, cannot afford a second “Tanker War” in one of its most important waterways.
