Since the outbreak of the Iran-Iraq War in February 2026, the Strait of Hormuz has been essentially closed, disrupting approximately 20% of global oil exports. The Houthi rebels are rapidly advancing in the Red Sea, paralyzing Saudi Arabia's east-west oil pipelines, and both the Bab el-Mandeb Strait and the Strait of Hormuz are under threat. The US is escalating its "economic isolation" efforts against Iran, sending alarm bells to both oil prices and inventories. Multiple conflicts in the Middle East are pushing the global energy market to the brink of danger, while the window for diplomatic solutions is narrowing.

I. Escalation of the Middle East Conflict on Multiple Fronts: Houthi Rebellion Attacks Saudi Arabia Again, Tanker Incident Remains a Rashomon-like Event

Yemen's Houthi rebels launched another large-scale attack on Saudi Arabia on Monday (September 14). According to Al-Masirah TV, controlled by the Houthis, the group fired dozens of ballistic missiles and drones at the King Khalid Air Base in Khamis Mushait, southwestern Saudi Arabia, targeting fighter jet hangars, radar systems, runways, and ammunition depots. Houthi spokesman Yahya Sarreya stated that the operation was in retaliation for over 300 airstrikes launched by Saudi Arabia against Yemen in the past five days using F-15 and Typhoon fighter jets. The Saudi Civil Defense Authority subsequently issued emergency security alerts for southern cities including Khamis Mushait and Abha. On the same day, regarding an oil tanker incident in the Strait of Hormuz, the US and Iran offered conflicting accounts. Iran's Fars News Agency reported that the Iranian Revolutionary Guard stated that the Panamanian-flagged oil tanker El Gaia struck a mine while passing through what it claimed to be a restricted area, subsequently exploding and catching fire. However, the U.S. Central Command immediately responded, stating that the report was untrue, and that the oil tanker was "hit by an Iranian missile last month and rendered incapable of navigation." The Iranian Revolutionary Guard issued a statement emphasizing that the Strait of Hormuz is closed and remains under Iranian "smart control." According to the International Maritime Organization (IMO), since the start of the Iran-Iraq War on February 28, there have been 79 incidents in the Strait of Hormuz, resulting in the deaths of 22 seafarers.

II. Diplomatic efforts falter: Talks between Gulf states and Iran postponed

The meeting between Iran and Gulf states, originally scheduled for September 14 in Salalah, Oman, has been postponed. The meeting was intended to discuss a negotiated plan to reopen the Strait of Hormuz. Omani Foreign Minister Badr Al-Busaidi stated on social media that the postponement was to ensure "appropriate conditions are met for constructive dialogue, thereby helping to reach a sustainable consensus supporting regional security and stability." Iran stated that the meeting was postponed at the request of Saudi Arabia. The talks had previously been highly anticipated. Iranian Foreign Minister Araqchi had stated that the meeting planned to introduce the details and complete route map of the new navigation route plan for the Strait of Hormuz, already agreed upon by Iran and Oman, to all participating regional countries. However, Araqchi also drew a red line: Iran's reopening of the strait is contingent on the United States fulfilling its commitments under the Islamabad Memorandum of Understanding. Bahrain had previously explicitly refused to attend, citing the lack of restored diplomatic relations with Iran. It is noteworthy that Saudi Arabia proactively requested a postponement on the eve of the meeting, reflecting the country's predicament of fighting on two fronts simultaneously—countering military pressure from the Houthi rebels in Yemen and dealing with the export crisis following the attack on a key oil pipeline. The differing positions among the Gulf Arab states also add uncertainty to the prospects for future dialogue.

III. New Front in Sanctions: The US Targets Russia's VTB Bank

On September 14, local time, the U.S. Treasury Department announced additional sanctions against VTB Bank, designating it as a key financial node in the Islamic Republic of Iran. U.S. Treasury Secretary Scott Bessant stated in a press release, "The Treasury Department will not tolerate any support for the Iranian regime and will continue to identify, expose, and isolate Iran's accomplices." According to U.S. accusations, VTB Bank has been assisting Iran in transferring frozen assets and establishing a national currency settlement system through proxy accounts in the Iranian rial and Russian ruble to facilitate trade between the two countries. The U.S. Treasury Department also warned that financial institutions continuing to transact with VTB may also face sanctions. This sanction is the latest move in the Trump administration's "economic isolation campaign." VTB Bank was already on the U.S. sanctions list in 2022 due to the Russia-Ukraine conflict, and existing sanctions already prohibit any U.S. individual or institution from transacting with it. Therefore, the direct marginal impact of the new sanctions is limited, but its core intention is to pressure international partners to sever business ties with the bank. Recently, the U.S. Treasury Department also imposed sanctions on some banks in Turkey and the UAE, and severed the connection between the UAE branch of the Egyptian state-owned bank Banque Misr and several large U.S. banks' agent accounts.

IV. Market Volatility: Soaring Oil Prices and Supply Chain Disruptions

The escalating tensions in the Middle East triggered significant volatility in the international crude oil market. On September 14, Brent crude futures rose more than 4% to $109.72, a new high since May 21, while WTI crude rose nearly 5%, breaking through $104.95 per barrel. Ultimately, Brent crude closed up about 1% at $105.68 per barrel, and WTI closed up 1.34% at $101.39 per barrel. The average retail price of diesel in the United States hit a record high on Monday, breaking through $6.23 per gallon. Tight supply was the core factor driving up oil prices. Analysts pointed out that oil outflows from the Bab el-Mandeb Strait in August had fallen to an average of 2.46 million barrels per day, a 65% decrease from June. Saudi Arabia's total crude oil exports in August fell to approximately 3 million barrels per day, the lowest level in at least nine years. While exports rose to nearly 4 million barrels per day in early September, about 1 million barrels were exported via the Strait of Hormuz, and the remainder were transported through the port of Yanbu on the Red Sea. The East-West oil pipeline was forced to close after last week's attack, and Yanbu's inventory is only sufficient to sustain exports for 5 to 7 days. Once depleted, up to 4% of global oil supply could face disruption. Inventory data is equally worrying. The US Strategic Petroleum Reserve decreased by approximately 3.6 million barrels last week, falling to 285 million barrels, the lowest level since 1982. OECD commercial crude oil inventories are also at their lowest level since 2003, lacking sufficient buffer reserves to offset supply shocks. The International Energy Agency projects that global oil supply will decrease by an average of 5.7 million barrels per day to 100.7 million barrels per day by 2026, and a full recovery of oil supply in the Gulf region is expected to be delayed until 2027.

Editor's Summary

The current situation in the Middle East is characterized by the simultaneous deterioration of conflicts on multiple fronts. The Houthi military advance in the Red Sea and the continued blockade of the Strait of Hormuz are creating dual pressures, putting Saudi Arabia in an unprecedented energy export predicament. The postponement of diplomatic dialogue between the Gulf states and Iran indicates that irreconcilable differences remain among the parties regarding core interests. The US sanctions against VTB Bank reflect Washington's attempt to further compress Iran's external economic space through financial means. From a market perspective, global crude oil inventories are at multi-year lows, idle capacity is limited, and alternative transportation routes are being blocked; these three factors combined significantly amplify the sensitivity of oil prices to any supply disruptions. Key variables to watch for in the future include: the restoration of navigation in the Strait of Hormuz and the Bab el-Mandeb Strait, the progress of repairs to Saudi oil pipelines, and whether the US and Iran can resume substantive negotiations after the midterm elections.

Frequently Asked Questions

Q1: Why did the Houthis launch a large-scale attack on Saudi Arabia at this time? The Houthis claimed that the attack was retaliation for Saudi Arabia's more than 300 airstrikes against Yemen in the past five days, conducted by F-15 and Typhoon fighter jets. Strategically, the Houthis have made rapid progress in the Yemeni battlefield recently, capturing several strategic locations, including Perim Island at the entrance to the Red Sea and the town of Zubab, essentially achieving full control of the Bab el-Mandeb Strait. Against this backdrop, the attack on the Saudi airbase was both a military retaliation and an attempt to weaken Saudi Arabia's air strike capability against Yemen, consolidating its own strategic advantage along the Red Sea coast. In addition, the Houthis have publicly urged Washington not to intervene in the conflict, showing their intention to use military pressure to keep external forces neutral. Q2: Why are the US and Iran's accounts of the El Gaia oil tanker incident so different? The Iranian Revolutionary Guard claimed that the oil tanker struck a mine and exploded while passing through a "restricted area," while the US Central Command claimed that the oil tanker was hit by an Iranian missile last month and lost its navigation capability. The core difference between the two sides' accounts lies in the attribution of responsibility for the incident. Iran attributed the tanker accident to mines, suggesting it was a legacy risk of war; the US, however, pointed the finger at Iran's own military actions. Since the outbreak of the war, there have been 79 incidents in the Strait of Hormuz, resulting in the deaths of 22 sailors, and shipping safety has escalated from isolated incidents to a systemic risk. Question 3: What are the reasons for the postponement of the talks between the Gulf states and Iran? The immediate reason is Saudi Arabia's request for a postponement. There are three deeper reasons: First, Bahrain explicitly refused to attend, citing the lack of restored diplomatic relations with Iran; second, after the attack on Saudi Arabia's key oil pipeline, Saudi Arabia's attitude towards dialogue with Iran has become more cautious; third, Iran insists that the reopening of the Strait is contingent on the US fulfilling its commitments under the "Islamabad Memorandum of Understanding," and the US's wavering stance on negotiations makes it difficult for all parties to reach a consensus before the meeting. Omani officials explained the postponement as "to ensure that appropriate conditions are met for constructive dialogue," but the hope of easing tensions in the Strait through diplomatic channels in the short term has clearly diminished. Question 4: Why is the US sanctioning Russia's VTB Bank at this time? The US Treasury Department accused VTB Bank of helping Iran transfer frozen assets and establishing a national currency settlement system through proxy accounts in rials and rubles, assisting Iran in circumventing sanctions. This move is part of the Trump administration's "economic isolation campaign," intended to pressure international partners to sever ties with the bank. However, VTB Bank has been on the US sanctions list since 2022, and existing sanctions already prohibit any US individual or institution from transacting with it, so the direct marginal impact of the new sanctions is limited. Its more significant signal is that the US is expanding sanctions from Iranian domestic financial institutions to partner banks in third-party countries to build a broader financial blockade network. Question 5: What will be the future trend of oil prices? Is it possible for them to continue to climb? Oil prices are currently facing multiple upward pressures. Global crude oil inventories are at multi-year lows, with the US SPR falling to 285 million barrels, the lowest since 1982, and OECD commercial inventories also at their lowest level since 2003. More than 10 million barrels per day of production capacity in the Gulf region remains shut down, and the International Energy Agency predicts that a full recovery of Gulf oil supply will be delayed until 2027. HSBC warned that Brent crude could rise to $120 per barrel amid continued oil transportation disruptions. However, high oil prices are also suppressing demand, with the International Energy Agency predicting a 2.5 million barrel per day decrease in global oil demand by 2026. In the short term, oil price movements will be highly dependent on the developments in the Middle East. As of 09:35 Beijing time, Brent crude was trading at $4297.61 per barrel.
