US Treasury Unveils a Sweeping Sanctions Package
On Monday, Treasury Secretary Scott Bessent announced what he called an "economic D‑Day" for Iran, describing the new measures as the "single greatest financial offensive ever." The package, dubbed Operation Economic Outcast, seeks to sever all economic ties with Iran and isolate any country that continues to do business with Tehran. Bessent warned that the United States will "tighten the noose" around the Iranian regime, targeting its revenue streams, especially those of the Islamic Revolutionary Guard Corps.
The Treasury has identified five key sectors for immediate action: digital assets, technology, gold, aviation and shipping. In addition, almost 60 entities—ranging from individuals to vessels—have been added to the sanctions list. Bessent emphasized that any nation or organization that facilitates trade with Iran will be cut off from the global financial system.
While Bessent refrained from naming specific countries, he suggested that the former President would personally call world leaders to request the cessation of interactions with Iran.
Iran’s Two‑Year Counter‑Plan
Iranian Economy Minister Ali Madanizadeh responded on state television, stating that the country is "fully prepared" for the new sanctions. He announced a two‑year strategy designed to mitigate the impact of the U.S. measures. Madanizadeh also noted that neither China nor Russia has accepted the U.S. sanctions and predicted that other nations would resist them.
China’s Foreign Ministry echoed this sentiment, asserting that the sanctions and pressure tactics would not deter Beijing and that it would protect its interests as necessary.
Impact on Global Oil and Shipping
The conflict has already pushed global oil prices higher. The Strait of Hormuz, through which roughly one‑fifth of the world’s oil and gas passes, has effectively been blocked by Iran since the war began in late February. Iran has warned that it will shut down all regional oil exports if the war continues and has issued a fresh warning to shipping companies about passing through the strait without its permission.
Brent crude, the benchmark for global oil prices, rose to $92 a barrel on Monday. U.S. gasoline prices have surpassed $4 a gallon, fueling concerns over the cost of living and becoming a key issue for voters ahead of the mid‑term elections.
Expert Opinions on Effectiveness
Capital Economics’ chief climate and commodities economist, David Oxley, expressed skepticism about the immediate impact of the sanctions. He noted that with the U.S. naval blockade already constraining Iran’s oil exports, the "economic D‑Day" might have only a limited short‑term effect on Iran’s energy revenues. Oxley pointed out that about 90% of Iran’s oil goes to China—a country that has historically ignored U.S. sanctions and is unlikely to be deterred this time.
Historical Context and Future Outlook
The U.S. has escalated its pressure on Iran since the 2015 nuclear deal was partially dismantled. Former President Donald Trump’s April threat that "a whole civilisation will die tonight" unless Iran agreed to a cease‑fire was later moderated after diplomatic intervention. During the Biden administration, attempts to reinstate the 2015 agreement were not successful.
In addition to the sanctions, the U.S. announced a new intervention in the bond markets, pledging to buy more government debt to boost demand and lower borrowing rates. However, the effect was short‑lived, with long‑term borrowing costs rebounding the following day.
The new sanctions package signals a decisive shift in U.S. policy, aiming to cut off Iran’s financial lifelines and compel a return to compliance with international norms.
