Treasury Secretary Scott Bessent announced wide-ranging secondary sanctions against Iran on Monday, targeting illicit trade networks as the rial hit a record low of 2.02 million to the dollar amid a protracted six-month U.S.-Israeli military conflict and ongoing Strait of Hormuz shipping disruptions.
When the U.S. and Israel launched their military campaign against Iran in February, President Donald Trump vowed a swift victory. Nearly six months later, that initial optimism has collided with a grinding stalemate. On the heels of a failed 60-day ceasefire deadline, the conflict has battered the global economy, agitated Gulf allies, and depleted the U.S. arsenal, shifting primary war goals from curbing nuclear ambitions to prying the Strait of Hormuz out of Iranian control.
It was against this backdrop that U.S. Treasury Secretary Scott Bessent unveiled a sweeping new sanctions campaign. According to the Treasury announcement, the measures intend to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone. Bessent put international trade partners on notice, warning that nations continuing to do business with Iran should expect to share in its isolation.
Sanctions Expansion and the Rial Collapse
The renewed economic pressure targets a complex evasion network built by Tehran over years, encompassing digital assets, technology, and shipping sectors. Yet the much-anticipated rollout left some observers underwhelmed because Washington chose to hold off on immediate major new measures, focusing instead on expanding and stepping up enforcement of existing penalties while threatening stricter secondary actions against uncooperative countries.

That pressure lands on an economy already reeling from severe depreciation. The rial fell to a record 2.02 million to the dollar on the day of the announcement, intensifying an inflationary spiral. The International Monetary Fund expects Iranian inflation to approach 70 percent this year, with the economy contracting by more than 5 percent. Past economic shocks have triggered widespread domestic unrest, making the currency’s slide a critical gauge of whether financial pressure can break the ruling establishment.
At the same time, Tehran has lost key regional cushions. The United Arab Emirates, long a vital re-export hub and trading partner valued at roughly $21 billion in 2024 according to the World Trade Organization, recently suspended trade and financial transactions with Iran, as detailed by former Treasury officials and analysts tracking shifting sanctions evasion landscapes.
Tehran Threatens Retaliation Across Energy and Regional Corridors
Rather than capitulating, Iranian officials have vowed fierce retaliation. For months, Iran has restricted vessels in the Strait of Hormuz, a waterway handling a fifth of global pre-war energy supplies. Now, military leaders are threatening energy infrastructure far beyond the strait as alternative shipping routes emerge.

“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.”

Rezaei later warned in a televised interview that Tehran would retaliate in an earthquake-like manner. Iranian authorities have published a roster of 45 oil tankers accused of failing to comply with rules imposed on Hormuz shipping, threatening fines, detention, or confiscation. Meanwhile, Saudi Arabia and other Gulf producers have successfully rerouted millions of barrels daily through pipelines or around the strait, though overall export volumes remain well below pre-war levels.
Beyond the Persian Gulf, Iran’s Foreign Ministry raised alarms by suggesting it could target outposts farther afield, pointing specifically to U.S. refueling aircraft operating from Bulgarian territory. Foreign Ministry spokesperson Esmail Baghaei asserted that Tehran regards any nation supporting U.S. and Israeli military aggression as a participant in an act of war, raising the specter of strikes against European Union and NATO member states.
The China Factor and Unresolved Diplomatic Stakes
The ultimate efficacy of Washington’s strategy hinges heavily on Beijing. China purchased an estimated $31 billion in crude oil from Iran in 2025—accounting for nearly 45 percent of Iran’s government budget according to a report from the U.S.-China Economic and Security Review Commission—and bought more than 80 percent of shipped Iranian oil that year according to Kpler data.

Following Trump’s announcement, a Chinese Foreign Ministry spokesperson stated that Beijing opposes unilateral sanctions and that economic pressure would not resolve the crisis. While Secretary Bessent noted in July that Iranian oil imports dropped by approximately 40 percent from pre-war levels due to the U.S. naval blockade, it remains uncertain whether Beijing will fully sever purchases or if Washington will impose penalties on Chinese entities if trade continues.
As past experience demonstrates, maximum financial pressure often hardens resistance rather than forcing immediate diplomatic concessions. With the rial plumbing new depths, regional oil routes contested, and international buyers weighing their next moves, the confrontation stands at a critical juncture where economic leverage and military force remain inextricably linked.
