In a striking strategic shift, the Yemeni Armed Forces have escalated their conflict with the Saudi enemy to an entirely new level, declaring a naval blockade on Saudi shipping in the Red Sea and the Bab al-Mandab Strait under the equation of "blockade for blockade." This escalation comes as a response to the continuation of the air and sea blockade imposed by Riyadh on Yemen for twelve years, most notably the targeting of Sana'a International Airport and the prevention of humanitarian flights.

Within a few weeks, the Yemeni Armed Forces carried out a series of qualitative operations that included targeting Abha Airport, and Aramco refineries in Jizan, Yanbu, and Abqaiq, alongside targeting three Saudi oil vessels, and forcing 16 Saudi ships to retreat and avoid passing through Bab al-Mandab. These operations revealed a fundamental shift in the regional balance of power and redrew the map of global energy flows.

Naval Blockade: Immediate Response from Shipping Companies

International shipping companies did not need to test the Yemeni Armed Forces' capability to execute their threats; previous experiences during the battle supporting Gaza and its aftermath confirmed a firm conviction within global shipping circles that whatever emanates from Sana'a will be executed without hesitation. This was reflected in the swift compliance with the blockade on Saudi navigation. Reuters confirmed that two oil tankers carrying Saudi crude bound for Asia altered their course away from the Red Sea less than 48 hours after the Yemeni warning, while the Armed Forces announced the turning back of six ships within 24 hours of the blockade declaration. Conversely, maritime tracking companies observed complete disregard for the Saudi military statement that vowed to protect navigation, recognizing that Saudi promises do not stand against proven Yemeni capabilities.

The biggest surprise came from the specialized maritime magazine Lloyd's List, which definitively stated that the movement of Saudi crude oil tankers in the Red Sea has become virtually non-existent, as no passage of any Saudi crude oil tanker has been recorded since July 23. It added that at least 11 tankers stopped transmitting tracking system signals off the port of Yanbu in a desperate attempt to reduce their exposure to risks.

Port of Yanbu: The Alternative Artery Turns into a Target

Prior to the recent escalation, Saudi Arabia had increasingly relied on the port of Yanbu on the Red Sea as an alternative outlet for its oil exports following the disruptions witnessed in the Strait of Hormuz against the backdrop of American aggression against Iran. However, the Yemeni blockade turned this strategy upside down.

The specialized military website Defense Security Asia described the situation as a "strategic nightmare" represented by a "double choke-point" scenario, where both the Strait of Hormuz and Bab al-Mandab together have become a source of threat to Saudi oil export routes. The report emphasized that the timing of the Yemeni decision was marked by extreme precision, as it came at a phase when Saudi Arabia raised its oil loading rates via Yanbu to record levels exceeding seven million barrels per day, making the largest portion of Saudi tanker traffic fall within the direct threat range of Yemeni military capabilities.

Bloomberg, for its part, explained that any interruption of supply flows through the Red Sea would exacerbate the repercussions of war on international oil trade, especially since Saudi Arabia had come to rely primarily on this route following the effective closure of the Strait of Hormuz. It noted that Saudi oil exports via Yanbu reached a record level of up to 7 million barrels per day during the month preceding the escalation, which helped limit global supply disruptions; however, this route is now in the crosshairs of Yemeni fire.

Insurance Companies Strike the Saudi Oil Economy

Military strikes were not alone in paralyzing Saudi oil movement; a parallel economic blow came from the global insurance market in London, which effectively controls the ability of tankers to sail.

The British newspaper Financial Times revealed that several of the largest ship insurers in the Lloyd's market in London began excluding vessels linked to Saudi Arabia from war risk coverage in the Red Sea. Major firms (including Ascot and Navium) notified brokers that they were stopping war risk coverage for ships connected to Saudi Arabia or heading to Saudi ports on the Red Sea, alongside canceling a number of active insurance policies.

Other reports confirmed that insurance companies refused to accept insurance requests for war risks for ships linked to Saudi Arabia, with the decision also extending to ships flying any flag that docked at Saudi ports before continuing their route in the Red Sea. The Associated Press quoted sources in the maritime insurance sector stating that war risk premiums for ships transiting the Red Sea rose to about 0.75% of the ship's value, compared to about 0.3% prior to the blockade announcement.

Advanced Naval Intelligence: Yemenis Know Their Targets

The Maritime Executive, a newspaper specializing in maritime navigation and transport affairs, highlighted an advanced level of Yemeni capabilities, pointing out that operations do not cease and only some are officially announced. It suggested that the attacks are designed to lift the blockade on Yemen and avoid escalating the conflict, rather than merely being a plan to completely close Bab al-Mandab.

The paper stressed that the Yemenis trust their advanced naval intelligence capabilities and possess access that enables them to identify ships matching their attack criteria with extreme precision. It added that the Yemenis coordinate using multiple strike systems simultaneously to attack specific targets in an alarming move, noting that these new features confirm that preparations had been underway for a long time.

Billions of Dollars in Losses and Costly Alternative Routes

The maritime intelligence firm Windward expressed astonishment at the scale of Saudi losses, observing four ships hit within a short period, and Aramco's Jizan refinery subjected to missile strikes—with five thermal hotspots identified within the complex—in addition to strikes on Yanbu. It confirmed that oil loading volumes in Yanbu dropped by approximately 40% after July 19, from around 5.16 million barrels per day to around 3.09 million barrels per day.

Saudi Arabia resorted to adopting the Sumed route via Egypt and then the Cape of Good Hope, adding significant time and cost to trips, estimated at around $9 per barrel. The National newspaper explained that an oil shipment from Yanbu to South Korea takes about 24 days via Bab al-Mandab, compared to 54 days via the Suez Canal and circumventing the Cape of Good Hope—an increase of over four weeks, in addition to transport costs rising by about $2 million per shipment.

The Wall Street Journal pointed out that at least four Saudi crude oil tankers altered their course before reaching the Bab al-Mandab Strait and headed north, while Saudi Arabia attempts to compensate for losses by increasing the quantities of oil offered for loading from Egyptian ports on the Mediterranean. However, experts questioned the feasibility of this alternative route, stressing that the Sumed pipeline is capable of transporting less than 500,000 barrels per day only, while Saudi Arabia exports more than 6 million barrels per day via Yanbu.

Washington Hesitates: A Bitter Experience Prevents Escalation

The American position regarding the Yemeni escalation was fraught with caution, which was reflected in comments by Trump himself. Contrary to his usual style of threats, Trump stated on his "Truth Social" platform: "Since our last battle a year ago with the 'Houthis,' they have acted so far with great responsibility... I am very disappointed in them, because until now they have acted professionally and wisely."

Instead of attacking the Yemenis, Trump directed his threats toward Iran in an attempt to avoid opening a new front with Sana'a. The American network MSNOW commented on this position by stating that Trump has reasons for fear and anxiety, given past experiences with the Yemenis, noting that the American air campaign in 2025, which cost over a billion dollars in less than two months, failed to stop Yemeni operations and ended in a military agreement—the first of its kind since World War II.

The Wall Street Journal quoted US officials as stating that Washington does not wish to engage in a new military confrontation with Yemen. It added that the US naval presence in the Red Sea is limited, while other US forces continue operations in the Arabian Sea, coinciding with the challenges Washington faces in dealing with the closure of the Strait of Hormuz.

The New York Times revealed that the US and European nations expressed a lack of desire to join the naval coalition called for by Saudi Arabia, at a time when only 14 out of 51 invited countries joined. Western officials affirmed that the existing situation in the region's seas cannot bear further complexity.

Zionist Concern Over an Unbeatable Enemy

Within the Zionist entity, concern over the repercussions of the Yemeni escalation was clear. The Zionist economic newspaper "Calcalist" pointed out that the "Houthis" possess the ability to immediately affect oil prices in global markets through the blockade on Saudi navigation. It quoted Zionist commentator Doron Peskin stating that the fear in "Israel" centers on the doctrine of Ansarallah, who view Jews as the primary enemy, and thus targeting everything "Israeli" is among their priorities.

Zionist "Navy commander", Eliezer Marom, admitted in statements to "Ma'ariv" to failing in the battle against the Yemenis, saying: "We understand what is happening around us, and it is extremely difficult to defeat these people or win the battle against them." He added that "the Yemenis subdued European fleets in the Red Sea, and the Americans are unwilling to confront them," admitting that "at present, there is no solution to this issue."

Saudi Economy Contracts: The Numbers Speak

Repercussions were not limited to the oil sector alone. The Financial Times revealed that Saudi Arabia's Gross Domestic Product (GDP) recorded a year-on-year contraction of 4.8% in the second quarter of 2026—the sharpest quarterly decline since the coronavirus pandemic—driven by a steep drop in the oil sector by 24.7% as a result of shipping disruptions. The International Monetary Fund expects Saudi economic growth to slow to 1.7% during 2026.

Meanwhile, global oil prices crossed the $100 per barrel mark for the first time in two months, amid estimates by some financial institutions of the possibility of reaching $120 if the escalation continues. The American network CB News sounded the alarm that a complete closure of the Bab al-Mandab Strait could reduce global oil supplies by 7%, at a time when markets are already suffering from declining supplies due to the consequences of the war between the United States and Iran.

Limited Saudi Options

Middle East Eye affirmed that Saudi Arabia's options have narrowed further, after previous experiences proved that airstrikes failed to subdue or isolate Yemen. It explained that Sana'a's current objective does not appear to be closing Bab al-Mandab completely, but rather demonstrating its ability to raise the economic cost on Riyadh whenever it wishes in order to achieve Yemeni demands—foremost among them lifting the blockade, opening Sana'a Airport, and paying civil service salaries.

The US Institute for the Study of War suggested that the Yemenis' strategic calculations might change if Sana'a sees that expanding the scope of operations leads to extracting their wealth and breaking the blockade. The institute quoted analysts citing indicators that Saudi Arabia prefers expanding its military operations over lifting its long-standing blockade, in a gamble that could cost it dearly.

A New Equation in the Region

After twelve years of blockade, Saudi Arabia finds itself facing an entirely different reality: it must either lift its blockade on Yemen or bear the consequences of a naval blockade that no one doubts the Yemenis' ability to enforce in one of the world's most vital maritime navigation straits. Recent Yemeni operations have proven that the rules of the game have changed, and the cards that Riyadh thought were exclusively in its hands are today held solely by Sana'a.

The Economist quoted analyst Michael Knights as saying: "You cannot degrade the Yemenis' anti-ship capabilities to the point where they are unable to strike and sink a ship or two a month, and that is sufficient deterrence for shipping companies to simply stop transiting." It appears that the Yemenis understand this completely and are betting on it to extract their rights after more than a decade of blockade and aggression.
