How US sanctions on Iran ripple through global markets and consumers

New sanctions hit Iran's aviation, tech, and shipping sectors, amplifying pressure on global markets and energy prices.

The administration of United States President Donald Trump has announced new economic sanctions on Tehran, describing the measures as an “economic D-Day” as the US war on Iran approaches the six-month mark. US Treasury Secretary Scott Bessent announced the sanctions on Monday, alongside a naval blockade of Iranian ports. Bessent said the sanctions target key sources of Iran’s revenue, including its oil and gas industry, and called on countries around the world to cut economic ties with Tehran.

The Treasury Department said the sanctions will target Iran’s aviation, digital assets, gold, technology and shipping sectors, as well as impose sanctions on 60 specific individuals and vessels. Bessent also said on Monday that the new sanctions expose Tehran’s trade partners to secondary penalties. According to a Treasury Department release on Monday, the targets include ships based in or associated with countries including Singapore, China, and Hong Kong.

Grey-zone trade refers to both illegal, underground trade and trade that is unsanctioned but difficult. The Treasury Department said Iran has used cryptocurrency to circumvent its longtime sanctions and facilitate transactions involving the Islamic Revolutionary Guard Corps (IRGC) and members of the Iranian regime. The department also said Iran has used gold to help prop up the value of its currency amid economic instability.

The new shipping sanctions target Iran’s state-linked shipping fleet, which the Treasury Department alleges is being used to transport oil as well as “sensitive weapons components”. The technology sanctions are intended to restrict Iran’s acquisition of materials that could be used in its weapons programmes. The aviation sanctions target Iranian airlines that the Treasury Department alleges are being used to transport weapons and military personnel, as well as financial resources to Iran’s proxies.

Washington also indefinitely suspended several broad exceptions to its ongoing sanctions on Iran, including those covering academic exchanges, personal money transfers and certain sporting activities. Organisations currently engaged in those activities have until September 8 to wind down their operations. Ziemba says these measures “will have more effect on Iranians, not just the regime”.

Washington’s sanctions on Iran have been in place since 1979, after students took hostages at the US Embassy in Tehran, and increased over the next 45 years. Sanctions were briefly paused, however, after the administration of President Barack Obama and world powers signed a nuclear deal with Tehran in 2015. But the Trump administration withdrew from the deal during its first term, in 2018, bringing back old penalties while adding new ones.
