Tensions in the Middle East have escalated sharply after Iran warned that it could block crude oil exports from the region if military attacks by the United States and Israel continue. The threat, issued by Iran’s powerful military force, has heightened concerns about global energy security and triggered fresh volatility in international oil markets.
The warning came from the Islamic Revolutionary Guard Corps (IRGC), which declared that Tehran would prevent oil shipments from leaving the Middle East if hostilities persist. The statement has intensified fears about a potential disruption in global oil supply, particularly given the strategic importance of the Strait of Hormuz, one of the world’s most critical maritime corridors for energy transport.
Approximately one-fifth of the world’s crude oil supply passes through the Strait of Hormuz, making it one of the most vital chokepoints in global energy trade. Any disruption to shipping through the narrow waterway could have far-reaching consequences for international markets and energy-dependent economies.
In a statement released on Tuesday, the IRGC warned that it would not allow oil shipments to leave the region if the United States and Israel continue their military strikes against Iranian targets. The military organisation said the attacks had crossed what it described as a “red line,” adding that Iran would take decisive measures to protect its national interests.
According to the statement, Tehran would not permit “one litre of oil” to leave the Middle East if the military campaign against the country continues. The warning represents one of the strongest signals yet that Iran may attempt to use energy exports as leverage in the escalating conflict.
Analysts say such a move would dramatically affect global energy supplies, given the heavy reliance of international markets on oil transported through the Persian Gulf.
The threat drew an immediate response from Donald Trump, who warned that the United States would respond with overwhelming military force if Iran attempted to block oil shipments through the Strait of Hormuz.
Speaking during a news conference on Monday, Trump said any effort by Tehran to disrupt energy exports would trigger a severe retaliation from Washington.
“We will hit them so hard that it will not be possible for them or anybody else helping them to ever recover that section of the world,” the U.S. president said.
Trump’s comments reflect Washington’s longstanding position that it will defend freedom of navigation through international waters, particularly in critical energy corridors such as the Strait of Hormuz.
Despite the escalating rhetoric, Trump also struck a more optimistic tone regarding the duration of the conflict. The president suggested that the war could end much sooner than initially expected.
Earlier, Trump had indicated that the conflict might last as long as four weeks. However, in his latest remarks he expressed confidence that the fighting could conclude well before that timeline.
According to Trump, U.S. forces have already inflicted substantial damage on Iran’s military capabilities.
“We have hit them very hard,” he said, while predicting that the conflict would come to an end relatively quickly.
Nevertheless, the U.S. president did not clearly define what would constitute victory in the conflict.
While the United States has framed its objectives primarily around neutralising Iran’s missile capabilities and dismantling its nuclear programme, Israel has articulated broader goals.
Officials in Israel have indicated that their ultimate objective is to remove Iran’s clerical leadership structure from power.
In contrast, Trump has suggested that the conflict would only truly end once Iran has a government willing to cooperate with the United States.
This difference in stated objectives has contributed to uncertainty about the potential trajectory of the war and the conditions required for a ceasefire.
Iranian officials have strongly rejected Trump’s remarks, insisting that Tehran—not Washington—will determine how and when the conflict ends.
A spokesperson for the IRGC dismissed the U.S. president’s comments as “nonsense,” according to Iranian state media.
“We are the ones who will determine the end of the war,” the spokesperson said, signalling Tehran’s determination to resist external pressure.
Iran has also portrayed the conflict as a defensive struggle against foreign aggression, framing its actions as necessary to protect national sovereignty.
The escalating hostilities have already had a significant impact on maritime traffic in the Persian Gulf.
For more than a week, oil tankers have reportedly been unable to pass safely through the Strait of Hormuz, effectively halting shipments through the crucial passage.
The disruption has forced several oil-producing countries in the region to reduce or temporarily halt production as storage facilities begin to reach capacity.
Energy analysts warn that a prolonged closure of the waterway could trigger severe supply shortages in global oil markets.
Adding to the uncertainty surrounding the conflict is a major political development within Iran.
The country recently appointed Mojtaba Khamenei as its new supreme leader, a move widely interpreted as a signal of political defiance amid the ongoing war.
The leadership change occurred at a particularly sensitive moment, reinforcing perceptions that Iran intends to maintain a hardline stance in the face of external pressure.
Observers say the appointment could reshape Iran’s internal power dynamics and influence how the country navigates the conflict.
In a post on his social media platform Truth Social, Trump reiterated his warning that the United States would respond forcefully if Iran interfered with oil shipments through the Strait of Hormuz.
“If Iran does anything that stops the flow of oil within the Strait of Hormuz, they will be hit by the United States of America TWENTY TIMES HARDER than they have been hit thus far,” he wrote.
The message underscored Washington’s determination to keep the vital shipping lane open.
The intensifying conflict has already triggered sharp movements in global energy markets.
Oil prices surged dramatically following the outbreak of hostilities between the United States, Israel and Iran.
Brent crude, the international benchmark for crude oil prices, climbed by more than 30 percent on Sunday, at one point exceeding $119 per barrel.
The surge reflects growing fears that the conflict could lead to prolonged disruptions in global oil supply.
The spike also marks the first time oil prices have risen above $100 per barrel since the geopolitical turmoil triggered by the Russia–Ukraine war in 2022.
In an effort to calm markets and ease supply concerns, Trump said the United States could temporarily waive certain oil-related sanctions.
The announcement followed a conversation between the U.S. president and Vladimir Putin, during which the two leaders reportedly discussed global energy supply challenges.
Trump indicated that Washington might allow “some countries” to resume oil trade in order to stabilise global markets.
However, analysts say such measures may only offer temporary relief if the conflict continues to escalate.
The confrontation between Iran, the United States and Israel has raised serious concerns about the stability of global energy supplies.
Because such a large proportion of the world’s oil passes through the Strait of Hormuz, any sustained disruption could have profound economic consequences, potentially driving up fuel costs and intensifying inflation worldwide.
Energy experts warn that the situation remains highly unpredictable.
With both sides issuing increasingly forceful statements and military operations continuing, the risk of further escalation remains high.
For now, global markets, governments and energy companies are closely monitoring developments in the region—aware that the next move by any of the parties involved could significantly reshape the global energy landscape.
