The US naval blockade on Iran could continue indefinitely, according to the Trump administration, as Washington prepares stronger economic pressure while tensions around the Strait of Hormuz continue threatening global energy supplies.
Trump Administration Signals Prolonged Iran Pressure
President Donald Trump’s administration has indicated that the United States is prepared to maintain pressure on Tehran for as long as necessary, despite stalled efforts to reach a diplomatic settlement.
The warning comes amid escalating tensions surrounding the Strait of Hormuz, a strategically important waterway through which a significant share of global oil and liquefied natural gas previously travelled.
US Defense Secretary Pete Hegseth said American forces possess the capability to sustain a naval presence in the region indefinitely through rotating ships and personnel.
Hegseth Confirms US Military Capability
“Indefinitely the United States Navy can maintain a blockade like that because we’ll rotate ships in and out,” Hegseth told reporters during a visit to Panama.
His remarks reinforced Washington’s position that military pressure against Tehran could continue without a predetermined end date if negotiations fail to deliver an agreement.
The administration’s approach combines military pressure with increasingly aggressive economic measures intended to weaken Iran’s financial position and restrict its ability to fund military activities.
Treasury Secretary Scott Bessent also signalled that additional measures were coming, warning that Washington intended to impose unprecedented economic pressure on Tehran.
“Watch this space for more announcements coming next week,” Bessent said during an interview, indicating that further financial restrictions could soon be announced.
Strait of Hormuz Becomes Central to the Conflict
The confrontation has increasingly focused on the Strait of Hormuz tensions, with Iran seeking to use control over the strategic waterway as leverage in its dispute with Washington.
Tehran has demanded the removal of economic sanctions and the release of frozen Iranian assets before agreeing to restore unrestricted commercial shipping through the waterway.
Shipping Traffic Falls Sharply
Shipping activity through the strait has already fallen dramatically compared with levels recorded before the conflict, raising concerns among governments, energy companies and international traders.
Reuters reported that only eight vessels passed through the waterway on Tuesday, compared with an average of about 12 vessels during the previous 10 days.
The difference is even more striking when compared with the estimated 130 to 140 vessels that travelled through the strait before the war began.
Two vessels belonging to Abu Dhabi National Oil Company were also reportedly attacked while transiting the waterway, according to UAE state media.
The United Arab Emirates condemned the incidents as Iranian attacks, further increasing concerns over the security of commercial shipping in the region.
Washington Intensifies Economic Pressure
The growing confrontation has deepened concerns about Iran economic pressure, as Washington seeks to cut Tehran’s access to hard currency and weaken revenue generated through international trade.
The United States had temporarily lifted its blockade of Iranian shipping and ports in June, but restrictions were later restored after diplomatic efforts failed to produce a lasting settlement.
Those measures have compounded the damage caused by attacks on Iranian energy infrastructure during the conflict, placing additional pressure on Tehran’s already weakened economy.
Trump Favors Economic Measures
Trump has previously threatened to escalate military strikes against Iran, but his administration has recently emphasized economic measures as an alternative to expanding the military campaign.
The US president has also repeatedly claimed that Washington has “total control” over the Strait of Hormuz, a statement strongly rejected by Iranian authorities.
Trump is simultaneously facing domestic political pressure as the conflict contributes to elevated fuel prices and creates economic concerns for American households.
The situation could become politically significant ahead of the November midterm elections, particularly if energy costs remain elevated for an extended period.
Global Oil Supply Faces Growing Risk
The confrontation is also creating serious concerns about the global oil supply shortage, particularly as restrictions around the Strait of Hormuz threaten international energy transportation.
The International Energy Agency has forecast that global oil supply could fall by approximately 4.3 million barrels per day this year, equivalent to around four percent.
Energy Markets Remain Vulnerable
The latest forecast represents a deterioration from the agency’s earlier projection of a 3.7-million-barrel-per-day decline, highlighting the worsening consequences of prolonged disruption.
Oil prices nevertheless fell by more than two percent on Thursday as investors focused on weaker global demand expectations and increasing US crude inventories.
However, reports that Yemen’s Iran-backed Houthis targeted a Saudi Aramco refinery with drones revived concerns about further attacks against energy infrastructure.
Such developments could place additional pressure on global markets if the conflict spreads beyond the immediate areas surrounding Iran.
US Iran Conflict Threatens Global Growth
The US Iran conflict has raised concerns about the wider global economy, with economists warning that prolonged disruption could significantly reduce economic growth.
Some regions could potentially move toward recession if the conflict continues to interfere with energy supplies, shipping routes and international trade.
The crisis has also revived questions about an earlier ceasefire that ended intense bombing campaigns and created an opportunity for peace negotiations.
Hegseth Defends Washington’s Strategy
Asked whether declaring the earlier ceasefire had been a mistake, Hegseth declined to offer a retrospective assessment.
“I’m never going to comment on that,” he said, before defending the administration’s current approach to Iran.
“We’re doing exactly what we need to, to ensure that Iran never has a nuclear weapon,” Hegseth added.
Blockade Could Continue Without Deadline
For now, the Trump administration appears prepared to maintain military pressure while expanding sanctions and financial restrictions against Tehran.
The possibility that the US naval blockade on Iran could continue indefinitely means international markets may remain highly sensitive to developments around the Strait of Hormuz.
Any further disruption could affect crude oil prices, shipping costs, fuel prices and broader economic stability, particularly in countries heavily dependent on imported energy.
With diplomatic efforts struggling and both Washington and Tehran maintaining competing demands, the crisis remains unresolved.
The Strait of Hormuz therefore continues to sit at the heart of a confrontation whose consequences could extend far beyond the Middle East, potentially affecting energy markets and economies across the world.
