Houthi military spokesperson Yahya Saree claimed a ballistic missile strike on a Saudi oil tanker off the port of Yanbu, causing a fire on board and prompting other vessels to flee the area [29]. The attack adds a new armed actor to the broader maritime crisis affecting Middle Eastern shipping lanes, separate from but compounding the confrontation in the Strait of Hormuz, where Iran has threatened to close the waterway [6] and the US is maintaining a naval blockade of Iranian ports [29]. Satellite imagery has documented oil pollution in the strait from attacks on tankers [43], and war-risk insurance premiums for vessels transiting both Hormuz and the Bab el-Mandeb strait have risen from 1–3% of hull value to 7.5–10% [38].
The US Treasury announced "Operation Economic Outcast," a sanctions package targeting five sectors of Iran's economy — digital assets, technology, gold, aviation, and maritime transport — and nearly 60 entities, individuals, and vessels [1][4][20]. Treasury Secretary Scott Bessent described the campaign as "the single greatest financial offensive ever marshalled against an adversary" and warned that any entity facilitating money laundering for Iran would be removed from the US dollar system [10][24]. However, Bessent declined to specify target countries or a timeline, citing a "cure period" to allow entities to wind down Iran-related business before enforcement begins [13][23]. Bessent stated the objective was "to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone" [6][20].
President Donald Trump asserted that Iran is "completely collapsing" in a full economic and military death spiral [24][29]. Defense Secretary Pete Hegseth stated that the US could maintain the naval blockade indefinitely and that kinetic strikes in the Strait of Hormuz or around Iran remained possible [10][13].
Iranian officials dismissed the sanctions as a repetition of failed tactics. Economy Minister Seyed Ali Madanizadeh stated that Washington has tried and failed for years to cut Iran's economic arteries and predicted another defeat, adding that Tehran has a two-year plan to manage the sanctions [6][12][19]. Parliament Speaker Mohammad Baqer Qalibaf said Iran's trade partners do not take the threats seriously and that the US is not in an economic position to further restrict its relations with other countries [4][12]. Foreign Minister Abbas Araghtschi called the measures a sign of desperation, stating that the US shift from military operations to "the same old plans shows that they are desperate" [27].
Iranian security and military officials warned that any country cooperating with US sanctions would be treated as an enemy. Mohsen Rezaei, head of Iran's Supreme National Security Council, stated that "if the economic war continues, not a single drop of oil will be exported, neither through the Strait of Hormuz nor from anywhere in the Persian Gulf" [6][24]. Major General Ali Abdollahi, Chief of Staff of the Iranian Armed Forces, said retaliation could take the form of land, sea, air, or cyber operations [10]. IRGC spokesperson Hossein Mohebbi vowed heavy blows to US interests and energy chokepoints if Iran's infrastructure is threatened [19][23].
Independent analysts and Iranian officials framed the sanctions as an admission that the military campaign had failed. Sina Toossi, a senior fellow at the Center for International Policy, argued that "after nearly six months without a military or diplomatic victory, Washington appears to be trying to accomplish through intensified economic strangulation what military force has so far failed to achieve" [10]. Andrew Miller of the Center for American Progress stated the war has brought the US "no closer to eliminating Iran's nuclear programme or crippling the Iranian regime" [10]. International lawyer Reza Nasri, who has links to the Iranian foreign ministry, called the US announcement "a claim of jurisdiction over the world, and every sovereign state on Earth is its real addressee" [24]. University of Tehran professor Hassan Ahmadian said there is "not a single new sanction" and that the fanfare is a public admission of a step backward after military failure [24].
The sanctions and shipping disruption have produced global economic effects. US gasoline prices rose to $4.09 per gallon, gold prices rose 0.8% to $4,639.49 per ounce, and Brent crude fell more than 2% to $85.22 per barrel [2][5]. South Korea's crude oil imports fell 14.7% in volume while costs rose 21.1% due to the Hormuz crisis [44]. BBC Urdu reported potential 11% food price increases for Pakistan, along with higher costs for fertilizers, pharmaceuticals, and helium used in microchips [41]. John Deal of Post Oak Group warned that if sanctions provoke Iranian retaliation against Gulf shipping, Americans could feel the impact quickly through gasoline, diesel, airfares, freight costs, and inflation [2].
Gulf states face a structural dilemma between US pressure and geographic proximity to Iran. Lancaster University professor Simon Mabon argued that Gulf countries cannot change geography and must live and work alongside Iran [11][36]. The UAE suspended trade with Iran ahead of the sanctions announcement, and UAE Minister of State for Foreign Trade Thani bin Ahmed Al Zeyoudi said the decision has significant repercussions for the UAE, with economic experts warning of higher food prices [24][40]. French President Emmanuel Macron and Saudi Crown Prince Mohammed bin Salman issued a joint statement calling for restoring normal navigation in the Strait of Hormuz and rejecting any tolls or restrictions on passage [37].
China and Russia rejected the unilateral sanctions. The Chinese Foreign Ministry stated that sanctions and pressure do not help and that Beijing will do what is necessary to protect China's interests [23][24]. Chinese foreign ministry spokesperson Lin Jian warned that higher economic pressure will not end the war and could disrupt global financial stability [30]. Russian Deputy Foreign Minister Alexander Alimov said Moscow is ready to support mediation efforts and referenced an updated Russian security concept for the Persian Gulf that includes freedom of navigation through Hormuz [35].
Diplomatic mediation is underway on multiple tracks. Pakistan's Chief of Defence Forces Asim Munir visited Tehran to revive the Islamabad Memorandum of Understanding, with Iranian leaders indicating conditional willingness to de-escalate if Washington changes its behavior and honors prior commitments [7]. Oman is conducting mediation talks with Iran on a new shipping route through the strait, though Iran's Foreign Minister conditioned reopening on US compensation and fulfillment of six demands [31]. UN Secretary-General Antonio Guterres proposed a UN facilitation mechanism for registering and verifying ships transporting fertilizers through the strait [29]. Pakistan also decided to open trade corridors for Iran through its ports, with Commerce Minister Jam Kamal stating the move will increase Pakistan's strategic importance as a regional trade hub [42].
Analysts noted that the sanctions primarily burden ordinary Iranians. Ali Vaez of the International Crisis Group stated that sanctions have barely served to strangle Iran's middle class, which lost its capacity to pressure the Islamic Republic for reforms [9]. Tehran-based analyst Peiman Salehi assessed that Iran has much less room than in previous years to work around sanctions [2]. Rachel Ziemba of the Center for a New American Security characterized the measures as mostly incremental but part of an effort to intimidate remaining trading partners [2].
Oman's mediation talks with Iran on a Strait of Hormuz shipping route are in their final stages, though Iran conditions any reopening on US behavioral changes and compensation [31]. US Vice President JD Vance stated that the US is using diplomatic, economic, and military tools simultaneously and that the matter is not yet finished [31].
