Saudi Arabia's Red Sea Oil Route Falls Under Houthi Threat
Houthi blockade threat compromises Saudi Arabia's traditional escape route from Hormuz, forcing tankers to shut off transponders and reroute through the Suez Canal.
Brent crude futures hit $100 a barrel on Thursday (2026-07-23), rising for a fifth day after Yemen's Houthis said they struck two Saudi oil tankers, widening disruption to global oil shipping through both the Red Sea and the Strait of Hormuz.5
The attacks mark a direct challenge to a cornerstone of Saudi oil strategy. For years, the kingdom's answer to any disruption in the Strait of Hormuz has been to pump west through the East-West Pipeline to Yanbu on the Red Sea, which markets always saw as reassuring. That hedge is now compromised on both ends.7
Saudi Arabia had shipped record volumes of crude from its Red Sea terminals in the days before the threat, with tanker tracking showing 5.9 million barrels a day leaving the two terminals at Yanbu in the week up to July 17.3 The kingdom was already leaning on this route to offset Hormuz closures. Now the exit to the open ocean at Bab el-Mandeb is under a declared embargo.
On Tuesday (2026-07-21), a Greek-owned Suezmax, the Amazon, departed Yanbu with more than 1 million barrels of crude and switched its destination to the Suez Canal, according to ship tracking data.3 That is a longer, costlier voyage than the southern route, and it signals how seriously shippers are taking the Houthi threat.
At least one oil tanker carrying Saudi crude has transited the Bab el-Mandeb Strait with its transponder switched off since the Houthis announced the blockade, a practice that reduces the risk of detection but also removes the safety and communication tools vessels rely on.6 A dark tanker cannot be tracked, which traders say points to a market where the cost of moving oil is measured in risk as much as freight.
The consequences extend well beyond Saudi loadings. Egypt's Suez Canal had already been a beneficiary of the earlier Hormuz closure, with 529 oil tankers transiting in April, up 28% from a year earlier, according to state statistics agency CAPMAS.1 Revenue reached $419 million in April, the highest monthly figure since early 2024, when Houthi shipping attacks first escalated.1
The canal's rebound is fragile. The Houthi announcement directly threatens the Red Sea approach to Suez, which means the same ships that turned to the canal as an alternative now face a new layer of risk on the journey south.3 If tankers avoid the entire Red Sea corridor, Suez loses both its crude transits and the general cargo traffic that contributed 1,182 vessel transits in April.1
Egypt has lost an estimated $9 billion in potential revenue since the disruption began, CAPMAS data show.1 A recovery of the waterway's revenues to historical levels could be one of the biggest near-term positive shocks for the country's strained finances, though that outlook now looks more distant than it did a week ago.
The diplomatic backdrop has shifted. The cease-fire and memorandum of understanding between the United States and Iran are over, and U.S. Central Command restarted its blockade of all Iranian shipping and ports on Tuesday (2026-07-14), according to Foreign Policy.2 That raised the stakes in the region shortly before the Houthis escalated their own campaign.2
The Houthis said they would impose a maritime blockade on Saudi Arabia, a new front in an expanding conflict, and MarineTraffic analysts said on Wednesday (2026-07-22) that the "Bab el-Mandeb risk picture is deteriorating."4 Ships continue to turn away from the southern end of the Red Sea in response.3
What remains uncertain is whether the Houthis will define their blockade narrowly. It is not clear what the group will treat as legitimate targets or whether the threat will persist beyond an initial show of force.1 If the embargo holds, Saudi Arabia faces a scenario it has spent years preparing for: a closed Hormuz to the east and a threatened Bab el-Mandeb to the west, leaving the East-West Pipeline's Red Sea outlets as a risk corridor rather than a relief valve.
ICE Brent crude front-month settled at $86.23 a barrel as of 03:48 UTC on Wednesday (2026-08-26), far below the $100 spike on Thursday (2026-07-23). The premium has faded as the immediate threat cooled, but the structural problem remains. Saudi Arabia's export routes are now constrained at both ends, and the market has yet to price in what that means for the kingdom's ability to respond to the next escalation.
