SPECIAL REPORT | RED SEA & HORMUZ CHOKEPOINTS
Houthis Open a Second Front at Sea, Squeezing World Oil Through a Closing Vise
With Hormuz already shut, missile strikes on Saudi tankers in the Red Sea threaten the last easy exit for Gulf crude — and the fallout is landing on fuel, fertilizer and freight costs across agriculture.
Analysis · July 23, 2026
The Iran-backed Houthis claimed their first attack on commercial shipping in months, striking two Saudi oil tankers in the Red Sea with missiles and drones and, in the words of a Bloomberg report, “opening a new front in the U.S./Iran war that has already disrupted global energy supplies and rattled bond markets.”
The Saudi government confirmed an attack on the refined-products tanker Encelia, and the British navy reported a vessel struck near the Saudi town of Al Shuqaiq in the southern Red Sea. Reuters reported the Encelia was hit by a missile, and Saudi officials said one tanker was ablaze. Meanwhile, the U.S. carried out its 12th consecutive night of airstrikes on Iranian military sites, hitting missile and air-defense facilities, and President Trump has pledged to destroy one Iranian bridge or power plant for every shot Iran takes at vessels in the Strait of Hormuz. Brent briefly topped $95–$96 a barrel and is now pressing toward $100.
WHY THIS ATTACK IS DIFFERENT
Since Iran shut the Strait of Hormuz, the world’s workaround for Gulf crude has been Saudi Arabia’s East-West Pipeline, which carries up to 5 million barrels a day across the peninsula to Red Sea terminals at Yanbu — loading tankers that sail north to the Suez Canal or south through the Bab el-Mandeb Strait. The Houthi strike near Al Shuqaiq is aimed squarely at that escape valve.
If insurers and shipowners now treat the southern Red Sea the way they treat Hormuz, both exits from the Gulf are effectively compromised at once — a pincer no oil-market model was priced for.

THE MARKET READ
Oil has risen for a fifth straight session, with the U.S. reimposing its naval blockade on Iran and Secretary of State Rubio dismissing Tehran as “not serious” about peace talks. The conflict has already spilled beyond the two principals — Kuwait says Iran struck a desalination and power plant — and each widening raises the war-risk premium embedded in every barrel, every cargo and every insurance policy written on Middle East trade. Bond markets are caught between two fears: an oil-driven inflation impulse that keeps the Fed hawkish, and a war-driven growth shock. So far the inflation fear is winning, which is why yields have been rattled rather than rallying on safe-haven flows.

THE AG ANGLE — THREE TRANSMISSION CHANNELS
First, fuel. Harvest-season diesel is the most direct hit, and refined products (note the Encelia was a products tanker) are tightening faster than crude.
Second, fertilizer. The Arabian Gulf is a dominant supplier of seaborne urea, and Iran itself was a major urea exporter before the war. IFPRI has flagged the war’s fertilizer-market impacts, and prices have already surged — setting up a costlier 2027 crop budget for U.S. producers.
Third, freight and food security. A no-go Red Sea forces grain and container traffic around the Cape of Good Hope, adding 10–14 days and sharply higher costs, while wheat-import-dependent buyers in Egypt and North Africa — who take delivery through these very waters — face higher landed costs, a dynamic CSIS calls a genuine global food-security threat. Higher import bills for those governments historically translate into firmer world wheat demand at almost any price — supportive for U.S. and Black Sea wheat values but destabilizing for the region.
BOTTOM LINE
The Houthi strikes convert a one-chokepoint crisis into a two-chokepoint crisis. Unless the southern Red Sea can be kept insurable, the oil market’s remaining flexibility shrinks to a pair of pipelines — and $100 Brent stops being a ceiling and starts looking like a floor. For agriculture, the war is arriving through the cost side of the ledger first: diesel, fertilizer and freight, with grain trade flows next in line.
