Iran is facing severe economic disruption as a result of a multilayered blockade led by the United States, which has significantly curtailed the country’s ability to export oil and import essential goods. Since July, the U.S.-enforced restrictions have reduced Iran's oil loadings by approximately 85%, while simultaneously facilitating the transit of over one billion barrels of non-Iranian crude through the strategic Strait of Hormuz.
On the ground, thousands of trucks have accumulated at Iran’s borders with Turkey and Afghanistan, many of which have remained idle for weeks. These overland routes serve as Iran’s primary means to circumvent the U.S. air and naval blockade; however, extensive customs and security checks have created severe bottlenecks, slowing trade considerably. Transporting goods via land is also markedly more expensive, estimated to cost around four times as much as maritime shipping, adding further strain to an already flagged economy.
Iran’s domestic fuel reserves are dwindling, reportedly projected to last only two more months, while the broader economy is under severe pressure. The nation’s gross domestic product has contracted by over 10% in recent weeks, and its currency, the rial, has depreciated by half over the past year. Additionally, transportation firms now demand payments in hard currency, primarily U.S. dollars, rather than the local rial, complicating logistics further. At present, roughly 500 trucks cross daily from Turkey, a fraction of the approximately 20,000 trucks needed to replicate previous seaborne trade volumes.
Iran’s leadership maintains that the ongoing "economic war" must be lifted and demands the unfreezing of its assets in exchange for halting attacks on commercial vessels passing through the Strait of Hormuz—a maritime corridor Iran does not have the authority to close. Tehran reiterated these demands at the United Nations General Assembly earlier this week.
Despite these overtures, U.S. officials argue that time is working against Iran and advocate for a more comprehensive blockade strategy. This would include establishing land-based restrictions alongside existing air and naval measures, further isolating the country’s access to international markets without deploying troops. Expanding sanctions to encompass transportation and logistics sectors—such as trucking companies, freight forwarders, and dry ports—would elevate the risks these actors face with regard to losing access to the U.S. financial system.
Efforts are also underway to pressure Iran’s neighboring states to curtail banking services tied to Tehran. Turkey has revoked the license of Bank Mellat, and the United Arab Emirates banned Bank Melli under U.S. pressure. Iraq has been encouraged to limit payments for Iranian gas and electricity imports to humanitarian goods like medicine and food, reducing cash flow to Tehran.
Beyond economic measures, cyber operations have targeted Iranian financial institutions. Last year, attacks attributed to Israeli hackers compromised Bank Sepah, affiliated with Iran’s military, and disrupted a major Iranian cryptocurrency exchange, reportedly causing losses of $90 million. Similar cyber efforts from U.S. and Israeli agencies are anticipated to focus on freezing the regime’s payment networks used to compensate military personnel.
Critics of negotiations warn that lifting sanctions or easing the blockade prematurely would provide Iran’s leadership with the resources needed to sustain military activities and suppress domestic dissent. Notably, Iran resumed attacks on shipping eight days after signing a memorandum of understanding with the United States earlier this year.
U.S. officials suggest supporting internal opposition within Iran by enhancing internet access, providing financial assistance to workers and merchants, and targeting security commanders involved in suppressing protests. The objective remains to restrict the regime’s ability to fund its military and maintain control amid growing internal pressure.
As the situation evolves, the U.S. appears committed to maintaining and intensifying economic measures designed to curtail Iran’s regional influence and military capabilities, while encouraging political change from within the country.
