Tankers with Saudi crude turn back as Houthis open new front in US-Iran war
Two oil tankers carrying Saudi crude to Asia reversed course in the Red Sea after Houthi threats, as the US bombed Iran for an 11th straight night and a widening Middle East war disrupted two critical energy chokepoints.

Houthi naval blockade threats and escalating US-Iran strikes push Saudi oil tankers to turn back in the Red Sea, while Iran attacks US bases across the Gulf and oil prices climb above $91 a barrel.
Imagine two big pipes that carry oil from the Middle East to the rest of the world, like giant straws. One straw got blocked, so Saudi Arabia started using a backup straw through the Red Sea. Now the Houthis are saying they'll block that one too, so ships are turning around. Meanwhile the US and Iran are still fighting, and gas prices are going up everywhere.
Analysis
The Houthis Shut the Back Door
For months, Saudi Arabia had partially insulated itself from the closure of the Strait of Hormuz by piping oil across the kingdom to the Red Sea port of Yanbu, then loading tankers bound for Asia. That workaround kept millions of barrels per day flowing even as the Persian Gulf became a combat zone. The Houthi announcement of a naval blockade on Saudi Arabia, and the immediate U-turn of two tankers loaded at Yanbu, signals that this escape route is now also under threat. With both chokepoints — Hormuz at the Gulf exit and Bab el-Mandeb at the Red Sea mouth — effectively contested, the bulk of Saudi crude has nowhere easy to go.
President Trump told reporters the Houthis had not yet physically closed the Bab el-Mandeb strait, dismissing the blockade as rhetorical so far, but tanker captains are not waiting to find out. The commercial calculus has already shifted: the risk premium for transiting a war zone now exceeds the cost savings of the Red Sea route. According to the report, both affected tankers were bound for China and India, the two largest Asian buyers of Saudi crude, underscoring how quickly the disruption cascades into global energy markets.
A War That Spills Across the Region
The conflict, which the article dates to February 28 with US and Israeli attacks on Iran, has metastasized far beyond the original combatants. Iran struck US military sites in Bahrain, Kuwait, and Jordan, and reportedly hit Amazon infrastructure in Bahrain. The IRGC said two oil tankers caught fire in the Strait of Hormuz's southern shipping lane, and the UKMTO reported a tanker struck by a projectile whose crew abandoned ship. Kuwait reported drone and missile attacks on power plants that also produce fresh water — a particularly grim detail for desert states that already depend on desalination.
The human and financial toll is mounting. A health ministry official said 50 Iranian civilians have been killed and 500 wounded in US strikes. Defense Secretary Pete Hegseth told senators the war has cost $37.5 billion so far and is being fought without congressional authorization, requesting another $70 billion in supplemental funds. Trump confirmed 18 US service members have been killed. The war is, as the article notes, deeply unpopular at home — a factor that may shape how aggressively the administration escalates against the Houthis or Iran.
Oil Markets and the Ceasefire Lifeline
Brent crude climbed above $91 a barrel and US gasoline topped $4 a gallon on Tuesday, a more than 2% gain that reflects traders pricing in a genuine supply shock rather than mere rhetoric. A senior Iranian official told Reuters that Tehran received a mediator's proposal for a 10-day ceasefire aimed at salvaging the interim agreement signed in June, which itself replaced an earlier April ceasefire. The article is truncated before the details, but the signal is clear: both sides are probing for off-ramps even as the fighting widens.
For energy-importing economies, the math is unforgiving. A full closure of the Red Sea alternative would trap most Saudi exports and force Asian and European buyers to compete for whatever Gulf crude can still move, bidding up prices further. Each additional week of war adds billions in military costs, billions more in oil-supply premiums, and an unknown but growing casualty count. The mediator's 10-day proposal, if accepted, would buy time — but only if both Washington and Tehran decide the political cost of continued fighting now exceeds the cost of stopping.
Key points
- Two Saudi crude tankers bound for China and India turned back at Yanbu after Houthi blockade threats
- US is bombing Iran for an 11th straight night; Iran has activated air defenses over Tehran
- Iran struck US military sites in Bahrain, Kuwait, and Jordan, and a tanker was hit in the Strait of Hormuz
- Brent crude rose above $91 a barrel and US gasoline topped $4 a gallon on the supply fears
- Defense Secretary Hegseth said the war has cost $37.5 billion so far, with another $70 billion requested, and 18 US service members have been killed
A mediator's proposal for a 10-day ceasefire, reported by a senior Iranian official, could pause the fighting and allow tanker traffic to resume through both the Strait of Hormuz and the Red Sea. If accepted, even a short halt would let Saudi oil flows normalize and ease the price pressure that has pushed Brent above $91 a barrel.
If the Houthis follow through on their blockade threat and the Red Sea route closes, most Saudi exports would be trapped, forcing a severe global supply squeeze. The war is being fought without congressional authorization, has already cost $37.5 billion, and is widening across Bahrain, Kuwait, and Jordan — raising the risk of further escalation that could push oil prices sharply higher and deepen the political backlash at home.
