US Treasury Secretary Scott Bessent announced that Iran has not loaded a single barrel of crude oil onto a vessel since August 25. This marks a complete halt in Iranian crude exports and signifies a significant escalation in economic isolation efforts. Bessent posted on X that the rial has plunged to record lows and described the period as one of the most difficult in the country's history.

Sanctions target aviation and banking

The US Treasury has intensified economic pressure, securing commitments from allies to halt Iranian flights and block banking transactions. Bessent confirmed that envoys were dispatched globally to isolate the Iranian regime. The strategy aims to ground Iran's civilian fleet and cut off financial channels. Key allies including Turkey, Oman, the United Arab Emirates (UAE), and Iraq have suspended operations for Iranian airlines.

The UAE Central Bank blocked transactions involving branches of Iran's Bank Melli on Wednesday, citing violations of anti-money laundering and terrorist financing rules. Previously, Turkey revoked the operating license of Iran's Bank Mellat. Washington has also imposed sanctions on global companies doing business with Iranian airlines after September 23. Bessent noted that restrictions on the aviation industry have resulted in an 80% to 90% reduction in external flights.

Strait of Hormuz flows remain stable

Despite geopolitical tensions and Bessent's claims regarding tanker loading, oil shipments through the Strait of Hormuz have not been disrupted. US Energy Secretary Chris Wright stated that flows are averaging almost 13 million barrels a day. Independent data from Commodity Context confirms that more than 13.5 million barrels a day are clearing the strait on a seven-day average.

Robin Brooks, a senior fellow at the Brookings Institution, noted that tanker traffic is at its highest in months. He argued that Iran has lost asymmetric leverage over the US in negotiations. Oil ETFs such as the United States Oil Fund slipped 0.77% to $148.87, while Brent futures declined 0.18% to $102.13 at press time.

Iran's economy contracts sharply

Iranian government data reveals a severe economic downturn. Real GDP fell 10.1% year over year between late March and late June. The oil and gas extraction sector, a primary source of foreign currency, contracted by 26.4%. Inflationary pressures remain acute. Prices in July were 88% higher than a year earlier, while food inflation exceeded 128%. The rial has lost approximately half its value over the past year, trading at up to 2.4 million rials to the dollar on the open market as of September 8. Bessent also targeted Iranian rail and automotive conglomerates, stating these industries have been coopted by the regime and the Islamic Revolutionary Guard Corps (IRGC).

What the numbers show

The divergence between stable global oil throughput through the Strait of Hormuz and Bessent's claim of zero Iranian tanker loading since August 25 highlights the efficacy of financial isolation over physical blockade. While physical supply chains remain intact with over 13.5 million barrels a day moving through the strait, the 26.4% drop in extraction combined with 88% general inflation indicates that Iran's ability to monetize exports and import goods is severely impaired by banking restrictions rather than shipping disruptions.

Diplomatic stalemate persists

Iran proposed reopening the Strait of Hormuz within seven days if Washington lifted its blockade and unfroze assets. Trump rejected this offer, stating Iran is "losing so badly." Vali Nasr, a professor at Johns Hopkins University, described the proposal as demanding terms favorable to Iran.

Iran's Supreme Leader Ayatollah Mojtaba Khamenei mocked Trump and the US, saying that blows suffered by America and its allies had resulted in the US not daring to move past the Arabian Sea. Khamenei also said that the US would eventually be kicked out of the Middle East. Analysts warn the pressure could provoke further escalation. Hamidreza Azizi, a visiting fellow at the German Institute for International and Security Affairs, suggested Tehran may strengthen its position in the Strait ahead of US midterms to counter perceived desperation.

President Donald Trump stated on Monday that he personally believes Iran was responsible for the alleged terrorist attack aboard Flydubai flight FZ1073. The incident, which occurred last Wednesday, involved a co-pilot allegedly attacking the captain with an emergency crash axe inside the cockpit.

The Boeing 737 MAX 9 aircraft reportedly descended 17,400 feet in less than two minutes during the event. Trump made the accusation while speaking to the press, answering a question about Tehran's potential involvement by saying, "I do, I personally do," before walking away. This aligns with his comments from October 1, where he hinted at Iranian involvement "based on what I'm hearing."

Vance defers to intelligence agencies

Vice President JD Vance adopted a more cautious stance when asked about the same incident on Monday. He stated that he would defer to CIA Director John Ratcliffe for any official comments regarding Iran's role in the event. Vance emphasized that while the matter is under review, he has not yet encountered definitive evidence linking Tehran to the attack.

"I wouldn't say I've seen anything conclusive just yet," Vance said. He added that he did not want to get ahead of any announcements from intelligence officials.

Regional tensions and economic impact

The incident occurs amidst escalating tensions between Washington and Tehran. Iran's Security Chief Mohsen Rezaee warned that the country is facing one of its "most difficult periods" as the Rial continues to fall amid sanctions and economic restrictions imposed by the U.S. These measures are part of "Operation Economic Outcast," touted by Trump and Treasury Secretary Scott Bessent.

Despite the geopolitical strain, data from ship tracker Kpler indicates that oil flows out of the Middle East, including through the Strait of Hormuz, have exceeded pre-war levels. However, the United Kingdom Maritime Trade Operations Center (UKMTO) reported that attacks on vessels have also increased.

The divergence between the President's assertion and the Vice President's caution highlights the ongoing uncertainty surrounding the investigation. While Trump relies on informal information, Vance points to the absence of verified intelligence findings.
