For a quarter of a century covering the Middle East, I have watched crises unfold in cycles—escalation, brinkmanship, and, occasionally, de-escalation. But every so often, a moment arrives that feels qualitatively different. The declaration from Tehran this week is one such moment.
Mohsen Rezaei, the newly appointed Secretary of Iran’s Supreme National Security Council, has issued an ultimatum that fundamentally alters the strategic calculus of the Gulf region. His message to Iran’s neighbours is stark: any nation that aligns with Washington’s intensifying economic campaign will be considered a hostile entity. And the consequences will be seismic.
‘Not a Single Drop of Oil’
In an interview with state broadcaster IRIB, Rezaei did not mince words. “We tell all neighbouring countries not to enter the economic war against Iran,” he declared. “Anyone who does so will be considered an enemy.”
The hardline official outlined a three-stage regional strategy: first, negotiation and diplomatic engagement; second, an effort to persuade neighbours to distance themselves from Washington; and third, decisive action against those who refuse to comply.
The threat is not abstract. Rezaei warned that if neighbouring states join the US campaign, “not a single drop of oil will leave the Persian Gulf or the Strait of Hormuz.” He further vowed that alternative export routes would also be disrupted, and that the strategic waterway would remain sealed until the United States adjusts its policy.
This is not empty rhetoric. Iran has already asserted control over what is widely considered an international waterway, and Rezaei noted that discussions with Oman over management of the strait are ongoing.

Washington’s ‘Economic D-Day’
The Iranian warning comes in direct response to what President Donald Trump has described as “the most crushing economic operation ever taken against any country.” In a post on Truth Social, Trump declared an “Economic D-Day,” threatening severe consequences for any nation providing a “lifeline” to Iran.
Treasury Secretary Scott Bessent echoed this sentiment, promising “the toughest sanctions in history” and a “one-two punch” combining existing blockades with sweeping new measures. The details are expected to be unveiled at a press conference on Monday.
The Trump administration’s calculation appears clear: intensify economic pressure to force Tehran to capitulate without resorting to a large-scale military escalation. Bessent himself suggested that if Washington applied maximum economic pressure, “likely there will not be a large-scale kinetic restart.”

The View from Tehran: Resistance, Not Capitulation
But this calculation may be deeply flawed. As Sanam Vakil at Chatham House observed, Trump “once again appears to underestimate the resolve of Iran’s leadership, which views resistance rather than capitulation as the only viable path” to survival.
Iran’s leadership has repeatedly insisted that the country will not surrender under pressure. Foreign Minister Abbas Araghchi dismissed Trump’s plan as another failed US policy, describing the proposed economic pressure as “economic terrorism” that threatens the global economy and the sovereignty of nations worldwide.
President Masoud Pezeshkian has taken a more nuanced position, calling for an end to the conflict while emphasising that Tehran is in a “stronger position.” But there is little indication that Iran is prepared to make the concessions Washington demands.

A Region Held Hostage
The most immediate and pressing concern is the impact on Gulf states. Iran’s warning places its neighbours in an impossible position: align with Washington and face Tehran’s wrath, or maintain economic ties with Iran and risk US sanctions.
The strategic dilemma is acute. Iraq has already requested—and reportedly received—special permission for its oil tankers to pass through the Strait of Hormuz. This ad hoc arrangement may become a template for differentiated access, but it also exposes the growing fragmentation of Gulf security.
Meanwhile, the US military presence in the region is being reinforced. The USS George Washington aircraft carrier has arrived in the Middle East, adding fresh naval capability as Washington maintains its pressure campaign.

The Global Cost of Economic Warfare
What is often overlooked in these confrontations is the broader economic toll. The sanctions are already wreaking havoc on Iran’s economy—annual inflation reached 66% in July, with food prices up 128% year-on-year. The IMF projects Iran’s GDP will shrink by 5.4% this year.
But the pain does not stop at Iran’s borders. The global energy market is feeling the strain. Brent crude oil futures rose 2.36% following Trump’s announcement, and US gasoline prices are already 29% higher than a year ago. If the Strait of Hormuz were to close for an extended period, oil prices could surge to nearly $94 a barrel, pushing US inflation up by 0.6 percentage points.
As one analyst put it, the US is trying to make Iran pay for the economic war, “but the bill is also being sent to American petrol stations, household budgets and business balance sheets.”

What Comes Next?
The coming days are critical. The US Treasury’s announcement on Monday will provide clarity on the scope and scale of the new sanctions. Tehran will almost certainly respond, and the risk of miscalculation is dangerously high.
Iran has already demonstrated a willingness to escalate—threatening to target oil shipping routes, American economic interests in the region, and even locations linked to Iranian opposition groups. Rezaei has warned that Iran will “retaliate in a seismic manner” if Trump takes action.
The conflict has entered a new, more volatile phase. Iran’s threat to designate neighbours as enemies is not just a warning—it is a fundamental challenge to the security architecture of the Gulf. And as the pressure mounts on all sides, the question is no longer whether this crisis will escalate, but how far.
