Treasury Secretary Scott Bessent sought to calm investor anxiety over the Iran pressure campaign Thursday, asserting that a return to large-scale combat was improbable.
The complication for the administration, however, is that Tehran was listening closely.
Earlier this week, President Trump vowed an “economic D-Day” against Iran, pledging a “crushing” operation to “cripple” the regime. The U.S. offensive is formidable, blending wartime destruction, a naval blockade, and sanctions that have squeezed the Iranian economy more severely than at any point in decades.
Yet beneath the bellicose rhetoric lay a signal Bessent underscored Thursday: Trump has no desire to resume war. The president is pursuing an economic campaign after weeks of bombing Iran earlier this year and repeatedly pulling back from threats to re-escalate militarily.
Consequently, analysts argue, Trump faces a conflict defined by limited leverage, exposed vulnerabilities, and an emboldened foe. Even as Iran grapples with shortages and inflation, Trump confronts mounting political pressure from upcoming midterm elections, an unpopular war, and elevated gasoline prices—a volatile mix that may lead Tehran to perceive U.S. weakness and retaliate.
“They now perceive him as unwilling to escalate militarily,” said Dennis Ross, a former Middle East envoy for administrations of both parties, referring to Iran’s leadership. “That creates an incentive for them to demonstrate a willingness to escalate.”
Bessent told CNBC Thursday that the Treasury would detail new Iran measures at a press conference next Monday. He argued traders erred in driving up oil prices, contending the economic threats signaled no imminent return to full-scale bombing.
“If we are implementing maximum economic pressure, that likely means there will not be a large-scale kinetic restart,” Bessent said. “But I would emphasize, that is for now.”
Trump announced the impending “economic D-Day” in a Wednesday evening social media post, warning of “Economic Warfare and Isolation on an unprecedented scale.”
“These maniacs are on the ropes, and these HISTORIC MEASURES will cripple them and their ability to project terror worldwide,” Trump wrote on Truth Social.
A core challenge for Trump is his pattern of threatening massive destruction only to retreat. In June, he voiced fears that a prolonged war could plunge the U.S. into an economic “depression.” Polls show the conflict is broadly unpopular, increasingly so among Republicans, creating a political liability as a war he once called a “little excursion” approaches its sixth month.
In recent months, Iran has demonstrated an ability to absorb heavy American and Israeli bombardment while imposing costs on the U.S., including attacks on oil tankers in the Strait of Hormuz. U.S. gasoline prices remain over a dollar per gallon higher than pre-war levels, Persian Gulf bases have sustained severe damage, 18 U.S. service members have died, and munitions stocks have dwindled. Meanwhile, a diplomatic resolution—even a full reopening of the strait—remains out of reach.
Iranian resilience and retaliation appear to have driven Trump toward economic coercion. Analysts note the administration has already inflicted extraordinary economic pain, with the naval blockade compounding the damage from this spring’s bombing campaign.
A new escalation arrived Wednesday when the United Arab Emirates, a vital Gulf economic partner, announced it would cease all trade and financial transactions with Iran.
However, further escalation poses difficulties for Trump, who warned on Truth Social that “ANY country” offering Iran a “lifeline” would “itself face TREMENDOUS Economic Consequences.”
Iran’s most critical financial lifeline is China, the primary buyer of Iranian oil.
“China is the indispensable piece” of any economic pressure campaign against Iran, said Miad Maleki, a senior fellow at the Foundation for Defense of Democracies and former Treasury sanctions official.
“No substitute can absorb Iranian crude at China’s scale,” Maleki added.
Yet Trump has sought to improve ties with Chinese leader Xi Jinping, who is slated to meet Trump in Washington on Sept. 24. Analysts expect the administration to tread carefully regarding pressure on China ahead of the summit, raising doubts about how much further the U.S. economic campaign can escalate.
Bessent told CNBC that discussions with China on the matter would remain private.
“Iran has been under comprehensive sanctions for years,” said Edward Fishman, director of the Maurice R. Greenberg Center for Geoeconomics at the Council on Foreign Relations. “The only major step left is aggressively targeting Iran’s trading partners—above all, China.”
He added: “I’m skeptical Trump is willing to risk an economic war with China right now.”
Then there is the question of how Iran will respond under severe financial strain—particularly given the widespread assessment that Trump wants to avoid renewed warfare.
Ross predicted Iran would seek to apply fresh military pressure on the U.S. or its Gulf allies. That prospect underscores the uncertainty surrounding Trump’s long-term strategy as gas prices remain high, midterms approach, and munitions run low.
“I’ve not seen, throughout this process, the ability to think beyond the immediate next step,” Ross said of the administration’s Iran approach. “They’re playing checkers, not chess.”
