Crude oil markets experienced extreme volatility on Wednesday, with West Texas Intermediate (WTI) futures staging a dramatic intraday V-shaped reversal of more than $10 per barrel. The catalyst was a rapid shift in the narrative around the potential end of the ongoing military conflict between the United States and Iran, known as Operation Epic Fury.
Trump's Peace Signal Triggers Sharp Drop
Early in the trading session, U.S. President Donald Trump posted on his Truth Social platform that his administration was close to finalizing a memorandum of understanding with Tehran that could halt the blockade of the Strait of Hormuz. Trump wrote: “Assuming Iran agrees to give what has been agreed to, which is, perhaps, a big assumption, the already legendary Epic Fury will be at an end, and the highly effective Blockade will allow the Hormuz Strait to be OPEN TO ALL, including Iran.” The statement fueled a rapid risk-on rally that sent WTI futures for June delivery plunging to an intraday low of $88.66 per barrel, while Brent crude for July settlement dropped to $96.75 per barrel.
Iran's Countermove: The Strait Authority
However, the euphoric sell-off proved short-lived. By mid-morning, Iranian state media announced the establishment of the “Persian Gulf Strait Authority” (PGSA), a new regulatory body tasked with overseeing maritime transit through the Strait of Hormuz. The PGSA launched a website that hinted at the collection of fees for passage and the enforcement of rules set by the Iranian government — a direct challenge to Washington's demand for unconditional freedom of navigation.
The Islamic Revolutionary Guard Corps (IRGC) Navy Command issued a statement thanking ship captains and operators for their “cooperation in transiting the Strait of Hormuz in accordance with Iranian regulations”, and added: “With the end of threats from aggressors and under new procedures, safe and sustainable passage through the Strait will be possible.” This suggests that the IRGC already considers itself the de facto regulator of the waterway, regardless of any potential U.S.-Iran ceasefire agreement.
Market Reversal and Outlook
Oil prices snapped back immediately after the PGSA announcement. WTI June futures surged back above $96 per barrel, and Brent July futures topped $103 per barrel. The spread between the two benchmarks widened to nearly $7, reflecting heightened uncertainty over physical supply availability from the region. Traders described the move as a classic “risk-on, risk-off” whipsaw triggered by conflicting headlines.
The Iranian move effectively transforms the Strait of Hormuz from a blockade zone into a toll road. Even if Washington agrees to lift the naval blockade, commercial vessels will now face fees and regulations imposed by the PGSA. This could raise global shipping costs and ultimately feed into consumer energy prices. As of press time, the White House had not issued an official response to the authority's creation. Analysts warn that if the U.S. rejects Iran's unilateral jurisdiction, military tensions could escalate again, potentially pushing crude into triple-digit territory for an extended period. Conversely, if Washington accepts the fee framework, it would remove the immediate blockade risk but embed a long-term tax on global oil trade. Either way, volatility is set to remain extreme.
