Global oil markets spiked sharply on Monday, with crude prices soaring above $100 per barrel after the collapse of US-Iran peace talks and a dramatic announcement by Donald Trump ordering a blockade of the strategic Strait of Hormuz, a vital artery for global energy supplies.
Negotiations held over the weekend in Islamabad broke down, with the US delegation—led by Vice President JD Vance—accusing Iran of refusing to abandon its nuclear programme. Tehran, however, countered by condemning what it described as “maximalism, shifting goalposts, and blockade” tactics from Washington.
The collapse of talks dashed hopes of ending the six-week conflict that has already rattled global markets. Oil prices, which had briefly eased last week following a ceasefire agreement, surged more than eight percent at one point, pushing both Brent and West Texas Intermediate crude above the $100 mark.
Equity markets reacted negatively to the escalating tensions, with major indices across Asia—including Tokyo, Hong Kong, Seoul, Sydney, Mumbai, Singapore, Taipei, and Jakarta—posting losses. Shanghai was a rare outlier, edging slightly higher.
In Europe, Hungary’s stock market rose more than three percent after Peter Magyar secured a decisive parliamentary victory, ending the 16-year rule of Prime Minister Viktor Orbán.
In a lengthy post on Truth Social, Trump declared that the United States would move to control maritime traffic in the Strait of Hormuz, stating that the US Navy would “blockade any and all ships” entering or leaving the waterway if linked to Iranian ports.
“Effective immediately, the United States Navy… will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz,” Trump wrote, warning that any hostile action would be met with overwhelming force.
The US military confirmed plans to blockade Iranian Gulf ports, effectively taking control of shipping routes in the region. In response, Iran’s Revolutionary Guards asserted that they retained full السيطرة over the strait and warned of severe consequences for any escalation.
Iranian naval chief Shahram Irani dismissed Trump’s threat as “ridiculous and funny,” according to state media.
Following the failed talks—the highest-level engagement between both nations since the 1979 Iranian Revolution—Vance said Washington had presented its “final and best offer,” while Iran’s Foreign Minister Abbas Araghchi insisted Tehran had negotiated in good faith and that both sides had been “inches away” from a deal.
Analysts warn the blockade marks a significant escalation. Nicole Grajewski of Sciences Po said such a move goes beyond symbolic pressure and could effectively signal a return to active conflict.
Market experts also cautioned that even if diplomacy resumes, oil prices may remain elevated. Malcolm Melville noted that restoring production levels could take weeks or months due to disrupted output and infrastructure damage, potentially keeping near-term oil prices high.
Still, Charu Chanana suggested the door to diplomacy remains open, pointing out that despite the breakdown, both sides had made some progress and could return to negotiations.
Beyond the US-Iran standoff, investors are also watching tensions involving Israel and Hezbollah. Lebanese Prime Minister Nawaf Salam said efforts were ongoing to secure an Israeli withdrawal and stabilize the region.
The prolonged crisis has heightened inflation concerns globally. Recent data showed US consumer prices rising to 3.3 percent in March—the highest level since May last year—adding pressure on central banks to maintain elevated interest rates.
