The first light of morning on September 10, 2026, fell on the silent cranes of the Al-Mokha port; a dock that had just fallen into the hands of the Houthis, 80 kilometers away from the chokepoint of Bab-el-Mandeb, on the same day Brent rose back to three digits, reaching 108 dollars; simultaneously, in U.S. coverage, an official assessment conveyed to reporters mentioned the 'presence of hundreds of Revolutionary Guards officers' in Yemen.
Al-Mokha fell on September 10; a city on the shores of the Red Sea located about 50 miles (nearly 80 kilometers) from Bab-el-Mandeb, and with its capture, the alternative maritime route to Hormuz for the passage of oil and goods came under closer threat. The next day, September 11, international media reported Saudi airstrikes on the airport of this newly captured city. The Iranian Foreign Ministry called for an end to the blockade of Yemen and the immediate resumption of talks that same morning.
In the information axis, a CNN exclusive report on the evening of September 10—published in English and Arabic versions and republished on local U.S. networks—cited American officials stating that 'hundreds of Revolutionary Guards officers' are present in Yemen, while 'over 100 U.S. military advisors' have been stationed in Saudi Arabia to assist in targeting and intelligence support in Riyadh's campaign. This narrative was complemented by Reuters' field reports on the role of 'direct guidance from the Guards' in the coastal advance of the Houthis.
As the battlefield map changed, Hans Grundberg, the UN Secretary-General's special envoy for Yemen, warned in an emergency Security Council meeting that the conflict had entered a 'new and more dangerous phase' and its consequences 'would not remain within Yemen's borders.' This warning coincided with the shifting battle lines along the Red Sea coast and the Houthis' approach to the Bab-el-Mandeb chokepoint.
The Route from the Port to the Chokepoint
In field reports and published images, Houthi forces were stationed in Al-Mokha on Thursday, September 10; four military sources from the Yemeni government told Reuters that the advance towards the southern coasts—Dabab and the Hanish Islands—continues to exert pressure on Bab-el-Mandeb. Regional media also reported on the same day that the Houthis were nearing complete control of the Red Sea coastal strip.
In terms of intelligence narratives, a Reuters analytical report stated that 'this week's rapid advance was conducted under the direct guidance of the Revolutionary Guards' and to support some operations against Saudi Arabia, 'several senior Guards commanders' traveled to and from Yemen. On the same day, CNN cited American officials assessing that the purpose of this arrangement is 'ultimately to close Bab-el-Mandeb.'
Based on official statements released, the Iranian Foreign Ministry denied any 'intervention' in Yemen and emphasized 'respect for Yemen's sovereignty.' This position was reiterated on the morning of September 11 in response to developments along the Yemeni coast, calling for a swift end to the blockade and a return to the negotiating table.
Energy Market: The Return of the Strait Premium
The oil market reacted swiftly: Brent closed at 101.21 dollars on September 9—the first settlement above 100 dollars since July 24—and on September 10, it peaked at 108 dollars in intraday trading, settling at 107.63 dollars. Reports on Thursday also recorded a jump to 105 dollars. Brent's return to three digits coincided with limited passage in Hormuz and increased risk in Bab-el-Mandeb.
On the same day, market sources and maritime agencies reported that several tankers and commercial vessels were targeted by fire, and the UKMTO confirmed several maritime incidents in the area; maritime data showed that traffic through Hormuz remained low and the physical routes of 'Dated Brent' had been priced above 100 dollars since September 3. This series of events returned the geopolitical premium to the price curve.
In analyses on September 10, commodity information institutions and market brokers pointed to several simultaneous drivers: the continuation of attacks on vessels, operational restrictions in Hormuz, the likelihood of ships rerouting to longer passages, and rising hull and war insurance costs. With prices stabilizing above 100 dollars, traders repriced inflationary scenarios and pressure on global growth.
Political Signals: From New York to Riyadh
On the political level, Grundberg's warning in New York coincided with calls from regional capitals. According to documented reports citing two American officials, Mohammed bin Salman, in two phone calls on Thursday, urged Donald Trump to take action against the Houthis; the main motivation was cited as the Houthis' approach to the Bab-el-Mandeb chokepoint. Simultaneously, Washington reinforced targeting and intelligence support for Saudi Arabia 'without direct involvement in the war.'
This political arrangement outside the battlefield reinforces the alignment of forces on the coast: according to Reuters reports, the Houthis, in addition to Al-Mokha, opened fire on positions on strategic islands to complete physical control over the waterway. Yemeni government sources stated that the advance along the Red Sea coast 'towards controlling' the chokepoint continues.
Publicly Established Certainties
By the morning of September 11, 2026, no international authority or involved party had confirmed the organized field presence of the Revolutionary Guards in Yemen in publicly available documents and statements; in contrast, Tehran's official position stands on 'denying intervention' and 'emphasizing Yemen's sovereignty.' At the same time, narratives published by CNN and Reuters reported respectively on 'the assessment of American officials regarding hundreds of Guards officers in Yemen' and 'direct guidance from the Guards in coastal advances'—two narratives that, in the public documentation realm, originated from informed sources and knowledgeable officials.
Risk Map for Transportation and Refining
As the Houthis approach the chokepoint, shipping companies face three choices: passing through Bab-el-Mandeb with higher risk and more expensive insurance; rerouting to longer paths (e.g., around Africa) with higher fuel costs and time; or temporarily suspending passage awaiting security guarantees. In Hormuz, analytical reports also indicate that traffic rates have significantly remained low. The convergence of these two pressures, especially for oil shipments from the Gulf and the Red Sea, raises the cost price.
For refineries in Europe and the Mediterranean, any disruption in the Red Sea directly affects feedstock costs. On the other hand, increased risk in Hormuz makes supply to Asian ports more expensive. Pricing data from September 9 and 10 indicates that the market has quickly factored this uncertainty into pricing.
Variable Coast, More Variable Prices
At the moment when the cranes of Al-Mokha stand silently, the big picture is this: a new chokepoint in the Red Sea is under pressure, the older chokepoint of Hormuz has not yet returned to normal traffic, and conflicting political signals—from UN warnings to Riyadh's requests for military action—send a message to the market that the range of oil price fluctuations could widen. In such a situation, any operational news about 'coastal control' or 'guaranteeing passage security' directly impacts the geopolitical premium on Brent.
The summary of data from September 9 and 10 is clear: Brent returned above 100 dollars and touched 108 dollars; Al-Mokha fell under Houthi control on September 10; the UN special envoy spoke of a 'more dangerous phase'; and in the published intelligence narratives, 'hundreds of Guards officers' and 'direct guidance' were recorded together. On the official side, Iran called for an end to the blockade and a return to dialogue. This arrangement will keep the geopolitical premium in the oil market until the operational control of the coasts and the guarantee of ship passage are clarified.
Why This News is Important
1) Supply Route: The proximity of the conflict to Bab-el-Mandeb, the second vital chokepoint alongside Hormuz, has simultaneously raised the risk for oil tankers and container shipping.
2) Energy Prices: Brent's return to three digits and touching 108 dollars on September 10 indicates that geopolitical shocks are immediately transferred to energy costs and global inflation.
3) Scope of War: The UN's official warning about a 'more dangerous phase' indicates that the consequences extend beyond Yemen's borders and spill over into global trade and energy security.
4) Coalition Arrangements: The deployment of 'over 100 American advisors' in Saudi Arabia and reports about the 'direct role of the Guards' in coastal advances indicate that regional contact lines have once again intersected in Yemen.
5) Insurance and Transport Patterns: Official maritime reports and market data regarding attacks on vessels and traffic rates indicate the establishment of a new risk premium in the maritime transport industry.
