Iran Threatens 'Unprecedented' Military Action as Oil Surges Past $112

Tehran’s threat of “unprecedented military action” over the U.S. blockade in the Strait of Hormuz sent fresh shockwaves through global markets.

An unnamed senior Iranian security official on Tuesday threatened “unprecedented military action” if the U.S. continues its maritime blockade, pushing international benchmark Brent crude futures above $112 a barrel and pulling U.S. equities from record highs. The comments mark a significant escalation in tensions that have effectively shut down one of the world’s most critical energy chokepoints.

"If America miscalculates again, we will burn its giant ships at sea," an official from the IRGC Navy’s political deputy said, according to state media reports. "We will respond to every new aggressive action with a new surprise."

The belligerent rhetoric sent Brent crude for July delivery up 2.7% to $104.40 a barrel, while the more immediate June contract settled at $111.26. In response, the S&P 500 fell 0.5% and the tech-heavy Nasdaq Composite dropped 0.9% as investors weighed the growing risk of a wider conflict. The CBOE Volatility Index, or VIX, jumped 1.23% to 18.05.

The standoff puts the Trump administration in a difficult position, as its rejection of an Iranian offer to reopen the critical waterway—which handles over a fifth of global oil supply—in exchange for a ceasefire without nuclear concessions leaves little room for de-escalation. U.S. officials said they remain skeptical of Tehran's proposals, insisting that the country's nuclear program must be addressed upfront. "That fundamental issue still has to be confronted. That still remains the core issue here," Secretary of State Marco Rubio said Monday.

Adding to the market’s instability, the United Arab Emirates on Tuesday announced it would formally exit OPEC on May 1, ending decades of membership. The move could eventually increase global oil supply as the UAE boosts production, but its immediate effect is to undermine the cartel's ability to coordinate and manage prices during a crisis. Oil prices initially fell on the news before rallying more than 4% from the lows as the Iranian threats took precedence.

The conflict's economic consequences are becoming increasingly visible. The World Bank warned Tuesday that the war is set to trigger the largest energy price surge in four years, disproportionately hitting developing economies. In the U.S., the average price for a gallon of gasoline climbed to $4.18, its highest level since the war began in late February, according to AAA.

Washington continued to tighten its financial chokehold on Tehran, with the Treasury Department announcing new sanctions against 35 entities and individuals accused of operating Iran's "covert financial network." Treasury Secretary Scott Bessent warned that the system serves as a "critical financial lifeline for its armed forces, enabling activities that disrupt global trade and fuel violence across the Middle East."
