The looming deadline, set by the Biden administration, marks the end of temporary exemptions that allowed certain countries to import Iranian crude without facing U.S. financial penalties. Trump, in a campaign speech posted to his social media platform on Tuesday, warned that if he returns to the White House, he will impose “the harshest oil export sanctions in history” on Iran unless the country abandons its nuclear enrichment program and cuts all financial and military support for proxy armed groups across the Middle East, including the Houthi movement in Yemen and Hezbollah in Lebanon. He added that any aggressive action from Iranian-backed groups against U.S. interests in the region would trigger immediate retaliatory measures targeting Iran’s energy infrastructure. Market analysts attribute the immediate oil price rally to widespread concerns that a full ban on Iranian crude exports would remove an estimated 1.4 million to 1.7 million barrels of oil per day from the global supply chain, a gap that current OPEC+ production cuts make difficult to fill in the short term. OPEC+ members, led by Saudi Arabia and Russia, have extended voluntary production cuts of 2.2 million barrels per day through the first quarter of 2025 to keep oil prices supported, leaving little spare capacity available to offset a sudden loss of Iranian supply. Additional upward pressure on crude prices comes from growing fears that heightened tensions between the U.S. and Iran could lead to further disruptions to shipping routes in the Red Sea, where Iran-backed Houthi fighters have launched repeated drone and missile attacks on commercial vessels since late 2023. Data from the U.S. Energy Information Administration (EIA) released earlier this week also showed that U.S. crude inventories fell by 3.1 million barrels last week, far exceeding analyst expectations of a 1.2 million barrel draw, further tightening domestic supply conditions. Investment banks have already upgraded their oil price forecasts following Trump’s remarks, with Goldman Sachs revising its 2025 Q2 WTI price target from $75 per barrel to $87 per barrel, noting that a full implementation of Iranian oil sanctions could push prices above $95 per barrel by mid-year.
