Two Chokepoints, One War: What the Houthi Blockade on Saudi Arabia Really Signals

The Houthis have opened a second maritime front against Saudi Arabia while Iran keeps attacking tankers in Hormuz — two contested chokepoints, one war, and a Gulf recalculating its alignment.

For nineteen years, every serious conversation about a US-Iran war started in the same place: the Strait of Hormuz. It is still the main event. But since July 20, a second front has opened eleven hundred kilometers to the southwest, at a strait twelve miles wide — and it may end up telling us more about how this war ends than Hormuz does.

The Blockade Nobody Fully Believes Yet

On July 20, Yemen's Houthi movement declared a "maritime embargo" against Saudi Arabia, promising to target ships tied to the kingdom moving through Bab el-Mandeb, the narrow gateway linking the Red Sea to the Gulf of Aden. Riyadh dismissed the declaration as disinformation and said it had kept humanitarian and commercial channels into Yemen open throughout the war. But the market didn't wait for a verdict. Within 48 hours, maritime intelligence firm Windward tracked five Saudi-linked tankers reversing course before reaching the strait, and shipping tracker Kpler recorded a 34% one-day drop in Bab el-Mandeb traffic. Two failed Houthi attacks on Saudi tankers followed within the week.

That gap — between a blockade nobody can confirm is operational and a shipping industry already rerouting around it — is the story. Tankers don't need certainty to change course. They need a plausible chance of a missile strike, and the Houthis have supplied that.

Now Reuters reports the Houthis are weighing a further step: charging transit fees on most Bab el-Mandeb traffic, modeled loosely on how Gulf states have floated managing Hormuz. Iranian officials reportedly raised the fee idea directly with Houthi representatives who traveled to Tehran this month for Ayatollah Khamenei's funeral. Whether or not fees are ever collected, the signal is the point: a second chokepoint is now contestable, and Tehran's allies control it.

Hormuz Hasn't Calmed Down Either

None of this happens in isolation from the main theater. Since July 6, roughly a dozen ships have come under attack in and around Hormuz, with the International Maritime Organization confirming two seafarer deaths and more than a dozen injuries. Iran has been pushing vessels toward routes that pass through its own territorial waters — a pattern read by analysts as pressure tactics rather than an attempt to fully close the strait, which would also strangle Iran's own trade.

Tehran has also rejected a mediation proposal from Oman that would have put Hormuz under joint regional management, funded by voluntary transit fees from shipping companies — an arrangement modeled on how the Strait of Malacca is handled. The rejection matters: it was the most concrete offramp on the table, and Iran walked away from it days before the Houthi blockade announcement. Read together, the sequence looks less like two unrelated crises and more like coordinated pressure on Gulf energy exports from two directions at once, timed to the period right after the ceasefire that ended Operation Epic Fury's main phase began fraying.

Why Riyadh Is the Target Now, Not Just Israel

For a Gulf audience, the more interesting shift isn't the tactic — it's the target. The Houthis spent 2023–2025 focused on shipping tied to Israel, a campaign that succeeded well enough to help shutter Israel's Eilat port before the Gaza ceasefire in October 2025 quieted things down. Saudi Arabia had largely stayed out of the direct line of fire, and CSIS analysts have noted the kingdom spent this war resisting full entanglement in the US-Iran fight even as it hosted joint strikes with US Central Command against Iran-aligned militants in Iraq.

That posture is now being tested from two directions: American pressure to align more fully with US-Israeli operations, and Houthi pressure aimed at making neutrality expensive. Bimco's shipping data underscores the stakes — Saudi Red Sea oil exports had climbed to roughly 4.7 million barrels a day in the March–June window, nearly triple the volume from a year earlier, as Riyadh diverted flows away from a contested Hormuz. Bab el-Mandeb wasn't a backup route. For several months, it was becoming the main one.

The Gulf Hedging Question

There's a broader story underneath the tanker movements, one CSIS's Middle East program has been circling for weeks: whether Gulf states are quietly concluding that alignment with Washington bought them exposure rather than protection. Decades of Gulf capital and security commitments were built on the bet that proximity to the US was the safest posture available. A war that keeps finding new ways to reach Saudi shipping — first through Hormuz, now through Bab el-Mandeb — puts real pressure on that bet, regardless of how the military campaign against Iran itself is going.

That's worth watching independent of who wins any single naval skirmish. If Gulf capitals start hedging their alignment more visibly — deeper outreach to China, quieter backchannels to Tehran, more public distance from US strike campaigns — that is arguably a bigger structural outcome of this war than any single chokepoint closure.

What to Watch Next

• Whether the Houthis actually collect a transit fee. A declared blockade is a warning shot; a functioning toll booth is control. The difference matters for how seriously shipping insurers price Bab el-Mandeb risk going forward.
• Iranian ballistic missile activity toward US forces. Central Command's confirmation of an intercepted Iranian strike on July 28, roughly a day after reports the US had paused new strikes, suggests neither side has actually settled into the ceasefire posture their public statements implied.
• Oman's mediation fate. Tehran's rejection of the Hormuz joint-management proposal removes the most concrete de-escalation mechanism currently on the table. Watch for a revived or reframed version of it once shipping losses mount further.
• Riyadh's posture. A kingdom that spent this war trying not to become a target now has to decide whether quiet non-alignment is still available to it.
