In the scenic setting of Asheville, North Carolina, where the world’s top financial leaders convened this week amid the Blue Ridge Mountains, Treasury Secretary Scott Bessent worked the sidelines to secure allied backing for an aggressive U.S. campaign to “economically asphyxiate” Iran. The phrase, delivered with deliberate bluntness, encapsulates the Biden administration’s strategy of squeezing Iran’s economy through an ever-tightening web of sanctions, trade restrictions, and diplomatic pressure.

Bessent, who took the helm of the Treasury Department earlier this year, has made Iran policy a cornerstone of his international engagement. During the meetings of the Group of Seven finance ministers and central bank governors, he held a series of bilateral talks with counterparts from Europe, Japan, and other key allies. The goal: ensure that the United States does not stand alone in its efforts to cripple Iran’s financial lifelines.

“We are seeing a growing consensus that Iran’s destabilizing activities cannot be tolerated,” Bessent told reporters on the margins of the summit. “The economic pressure we are applying is not just about sanctions; it’s about cutting off the oxygen that funds their nuclear program, their missile development, and their support for terrorist proxies.”

U.S. officials have long argued that Iran uses its oil revenues to finance activities across the Middle East, from arming Houthi rebels in Yemen to supplying drones to Russia for its war in Ukraine. The Biden administration, despite early efforts to revive the 2015 nuclear deal, has since shifted to a maximum-pressure approach reminiscent of the Trump era—though with a more diplomatic veneer.

Bessent’s push this week focused on three key areas: tightening the enforcement of existing sanctions, expanding the list of Iranian entities blacklisted by the U.S. Treasury, and persuading allies to adopt similar measures. The Treasury secretary emphasized that the campaign is not unilateral. “Our allies understand that a robust Iran is a threat to global stability,” he said. “They have been supportive, and we are coordinating closely to ensure our actions are complementary.”

European officials, however, have expressed reservations about the humanitarian impact of severe economic isolation. The United Nations and several aid organizations have warned that broad sanctions can exacerbate poverty and limit access to food and medicine for ordinary Iranians. Bessent acknowledged these concerns but insisted that the U.S. has built in exemptions for humanitarian goods. “We are not targeting the Iranian people,” he said. “We are targeting the regime’s ability to fund its malign activities.”

The summit in Asheville—hosted by the United States as part of the rotating G7 presidency—provided a rare opportunity for face-to-face diplomacy. The Blue Ridge Mountains, known for their misty peaks and winding trails, offered a stark contrast to the tense negotiations inside conference rooms. But the atmosphere was businesslike, with Bessent pressing his counterparts to commit to stronger enforcement mechanisms.

One area of particular focus is Iran’s use of front companies and shell banks to circumvent sanctions. The Treasury Department has recently designated several networks linked to the Islamic Revolutionary Guard Corps, and Bessent urged allies to share intelligence and freeze assets more aggressively. “We cannot allow Iran to exploit loopholes in the global financial system,” he said.

The push for economic asphyxiation comes as Iran’s economy shows signs of strain. Inflation is running at over 40 percent, the rial has lost significant value, and unemployment remains high. Yet Tehran has shown no sign of abandoning its nuclear program, which the International Atomic Energy Agency says has enriched uranium to near weapons-grade levels. The standoff continues to fuel tensions across the region.

Critics of the approach argue that maximum pressure alone has not worked in the past and risks pushing Iran toward further escalation. But Bessent and his team remain convinced that sustained economic pain, combined with diplomatic isolation, will eventually force Tehran to negotiate. “We are patient,” Bessent said. “We have the tools, and we have the partners.”

As the conference wrapped up, the official communiqué stopped short of explicitly endorsing the “asphyxiation” language, instead reiterating a commitment to “urging Iran to comply with its international obligations.” Yet behind the scenes, officials from several countries privately acknowledged that the United States has made headway. “There is a recognition that the status quo is unsustainable,” one European diplomat said on condition of anonymity. “We may not use the same rhetoric, but we understand the logic.”

Bessent’s performance in Asheville marks a defining moment for his tenure. With the G7 summit now concluded, the Treasury secretary will return to Washington to oversee the next wave of sanctions, while allies will begin implementing their own measures. Whether the coordinated campaign will succeed in changing Iran’s behavior remains uncertain, but for now, the United States appears to have the backing it sought.
