US Launches 'Economic D-Day' Against Iran

Treasury targets Iran's global trade networks with secondary sanctions, threatening to cut.

US Treasury Secretary Scott Bessent announced on Monday the launch of "Operation Economic Outcast," a sweeping sanctions campaign designed to isolate Iran by targeting international entities that facilitate Iranian trade in shipping, oil, cryptocurrency, gold, and aviation. The Treasury Department sanctioned nearly 60 corporations, individuals, and vessels across multiple jurisdictions. Bessent declared the US would launch an "economic onslaught" to "sever every economic pipeline" used by Iran "until Tehran stands alone." President Donald Trump is reportedly making phone calls to world leaders with specific requests to cease trading with the Iranian regime. Any entity that facilitates money laundering on behalf of Iran will be removed from the US dollar system, Bessent warned, adding that a "cure period" exists for nations to end targeted relations with Iran.

The newly sanctioned entities include multiple Chinese nationals and firms based in mainland China and Hong Kong. According to the South China Morning Post, these include Hong Kong-based Sweet Ocean Industrial Ltd, accused of serving as an intermediary for the procurement of sensitive goods for Iran's UN-sanctioned Malek Ashtar University of Technology. The newly designated Chinese nationals include Li Na, Qiu Xingyu, Tian Jianbai, and Zhang Limei, linked to various Hong Kong and Shenzhen-based logistics and technology firms. China has firmly rejected the US sanctions, with the Chinese embassy in Washington stating that Beijing stands against "illicit unilateral sanctions that have no basis in international law" and will protect Chinese businesses' rights. The Chinese foreign ministry vowed to take "all necessary measures" to safeguard its interests. The campaign's effectiveness may ultimately depend on how far Washington is willing to press China, which purchases 80 to 90 percent of Iran's exported oil.

The US announcement came as Iran's currency plunged to a record low. According to 6abc Philadelphia, the rial dropped to 2.02 million to the US dollar as trading opened on currency markets, while the official Central Bank rate stood at around 1.5 million rial to the dollar. The currency had already been under pressure before the US and Israel attacked Iran on February 28, as the country faced double-digit inflation and negative growth. Since the war began, rice prices in Iran have risen approximately 60 percent, and beef prices have increased by more than 150 percent. The International Monetary Fund forecasts that Iran's gross domestic product will contract by more than 5 percent. Despite this economic pressure, it has not yet translated into political change, as Iran's authoritarian government has tightened its grip on power since the start of the war.

Iranian officials downplayed the economic threat and vowed retaliation. Iran's Economy Minister Ali Madanizadeh, according to the semiofficial Fars news agency, stated, "You will fail this time too" and added, "The government is fully prepared for this economic war." Madanizadeh told ISNA that it would not be easy to cut the country off from global economic channels and warned, "If they take any action, they should expect an attack from us." Iranian Foreign Ministry spokesperson Esmail Baghaei told reporters in Tehran that "any escalation of this situation will undoubtedly bring about consequences," adding, "Our hands are not tied." The Guardian reports that Maj. Gen. Ali Abdollahi, the armed forces' chief of staff, said retaliation could take the form of land, sea, or air operations or cyberattacks. Iran has also warned it would retaliate against any neighbors that join the US-led economic efforts.

The sanctions announcement comes amid a six-month conflict that has seen kinetic combat and a US naval blockade of the Strait of Hormuz. According to NBC News, Defense Secretary Pete Hegseth said last month that the war has cost the US $37.5 billion, though estimates put the all-in economic impact at as much as $150 billion. Moody's Analytics chief economist Mark Zandi told NBC News the war has cost the average US household more than $1,200 in higher energy and grocery costs alone. The conflict has disrupted roughly a fifth of the world's traded oil supply, and Iran is refusing to fully reopen the strait unless it can charge ships. Pakistan, which played a key role in brokering a 60-day ceasefire in June, sent a high-level delegation led by Field Marshal Asim Munir to Iran on Monday to encourage both sides to return to negotiations.

Experts are skeptical about the effectiveness of the new sanctions, particularly regarding Iran's largest trading partners. Alan Eyre, a diplomatic fellow at the Middle East Institute, told NBC News that after six months of combat and blockade, the administration has few remaining levers to convince Iran's major partners to materially reduce economic ties. Andrew Gawthrope, a lecturer at the University of Leiden, told NBC News that countries like Russia and China see Iran as an ally and are unlikely to suddenly stop trading with it. According to the Atlantic Council, experts noted the sanctions announced were a "warning shot" rather than an economic death blow, and dealing a crippling blow would probably require taking on major Chinese firms and banks, which did not happen Monday. Bessent himself acknowledged he did not want to "blow up the global financial system."
