Trump Threatens to Seize Iran's Kharg Island as Brent Logs Record 59% Monthly Surge and Asia Markets Brace for Fresh Shock

Oil markets opened Tuesday on the edge of history. Brent crude is on course to post its largest monthly gain ever recorded — a staggering 59% rise since March 1 — as U.S. President Donald Trump escalated his rhetoric on Monday to an entirely new level, saying the United States was actively considering a ground operation to seize Iran's Kharg Island, the jugular vein of the Islamic Republic's petroleum exports.

Trump's statement, given in an interview with the Financial Times and reinforced in a Truth Social post, marks the most direct threat yet to a piece of oil infrastructure that handles nearly 90% of Iran's crude export flows. If carried out, it would fundamentally transform the conflict from an air war into a ground occupation of a strategically critical energy asset — with implications for global oil supply that would dwarf anything markets have already priced in.

"My Favourite Thing Is to Take the Oil"

The comments were striking for their directness. "To be honest with you, my favourite thing is to take the oil in Iran," Trump told the Financial Times on Monday, drawing a comparison to the administration's stated intent to control Venezuela's oil industry "indefinitely." He acknowledged a Kharg Island operation would require a sustained U.S. presence, adding: "It would also mean we had to be there for a while" — while dismissing Iranian defensive capabilities. "I don't think they have any defence. We could take it very easily."

Later Monday, Trump posted on Truth Social threatening to "obliterate" Iran's electricity-generating plants, oil wells, Kharg Island, and "possibly all desalination plants" if Tehran does not agree to a ceasefire and reopen the Strait of Hormuz "shortly." He simultaneously claimed "serious discussions" were underway with what he characterised as "a more reasonable regime in Tehran," setting an April 6 deadline for the Islamic Republic to accept a deal.

The mixed messaging — escalation threats issued alongside claims of diplomatic progress — is becoming a signature of this administration's conflict management, but markets are responding to the hard edge of the threat, not the diplomatic softening.

Record Monthly Oil Surge: 59%, Eclipsing the Gulf War

The numbers are historic. Brent crude surged to approximately $117 per barrel in Asian trading Monday, while West Texas Intermediate settled just above $103 per barrel — the first time U.S. crude has traded above $100 since 2022. Brent is now tracking a 59% monthly gain for March, surpassing the previous record of 46% set in September 1990 following Saddam Hussein's invasion of Kuwait.

The International Monetary Fund warned this week that "all roads lead to higher prices and slower growth worldwide" should the Hormuz crisis persist. Shipping traffic through the strait — which once carried a fifth of global seaborne oil — has virtually ground to a halt since U.S. and Israeli forces launched strikes on Iran on February 28.

The International Energy Agency has described the disruption as "the greatest global energy security challenge in history."

Goldman Sachs, which had already called this the largest oil supply shock on record, is now tracking Brent averaging above $110 through April. JPMorgan has raised its year-end gold forecast to $6,300 on structural demand from central banks and surging safe-haven flows — the People's Bank of China extended gold purchases for a 15th consecutive month in March.

Pentagon Deploys 10,000 Ground Troops

The Pentagon has ordered the deployment of approximately 10,000 troops trained for ground operations to the Middle East, with thousands already arriving — including Marines and units from the 82nd Airborne Division. The scale of the build-up strongly suggests Washington has at minimum seriously war-gamed a Kharg Island seizure operation.

Iran's response has been defiant. Foreign Ministry spokesperson Esmail Baghaei acknowledged Tehran had received a 15-point proposal from the Trump administration following talks brokered by Pakistan, Egypt, Saudi Arabia, and Turkey — but described the demands as "excessive, unrealistic and irrational." Iran's parliamentary speaker Mohammad Bagher Ghalibaf dismissed the diplomacy entirely, saying Iranian forces were "waiting for the arrival of American troops on the ground to set them on fire."

Tehran struck a critical water and electrical plant in Kuwait and an oil refinery in Israel on Monday. Israel and the U.S. launched a new wave of strikes on Iran. Yemen's Houthi rebels fired missiles at Israel for the first time since the war began on Saturday, opening a second front. Spain announced its airspace was closed to U.S. military aircraft involved in the conflict, an indication of widening international friction.

Asia Markets Open Lower Tuesday

Asia-Pacific equity markets opened lower Tuesday morning, tracking the deterioration in risk sentiment. Australia's S&P/ASX 200 fell 0.30% in early trade. Japan's Nikkei 225 futures pointed toward a decline, with the Chicago contract at 51,100 versus the index's Monday close of 51,885. Hong Kong's Hang Seng futures indicated a softer open at 24,683 versus the last close of 24,750.

The selloff reflected investor anxiety over what an actual Kharg Island seizure operation — versus a threat — would do to the remaining slivers of Middle East oil supply that have been rerouted through Saudi pipelines and alternate routes. Saudi Aramco's 5 million barrel-per-day East-West Pipeline, routed to the Red Sea, has become one of the only functioning arterial routes for Gulf crude — but it too would face vulnerability in a broader regional conflict.

The $117 Question: Can Markets Price an Occupation?

The current oil spike is being driven by an air war and shipping blockade. A ground operation seizing Kharg Island would effectively mean the U.S. military taking direct custody of Iranian crude infrastructure — an outcome with no modern precedent and legal implications under international humanitarian law that human rights organisations, including Amnesty International, have already flagged as potentially amounting to a war crime.

"The risk of further escalation, including a US ground operation to seize Kharg Island, continued to send tremors through financial markets," the Guardian noted Monday, summarizing the dominant market narrative.

Egyptian President Abdel Fattah al-Sisi made an unusually direct public appeal to Trump: "I say to President Trump: no one will be able to stop the war in our region, in the Gulf… Please, help us to stop the war, you are capable of it." The UK's Keir Starmer reiterated: "This is not our war and we are not going to get dragged into it."

The IMF's global recession warning, the Fed holding rates steady amid stagflation risks, Asian central banks already in emergency mode — and now the spectre of a ground invasion that would lock up nearly all of Iran's crude exports for an indefinite period. The April 6 deadline Trump has set is six days away. Oil markets, quite literally, are watching the clock.
