Trump's May 6 Ultimatum Puts Strait of Hormuz in Play

Former President Donald Trump on May 6 issued a direct ultimatum to Iran, stating that the U.S. military campaign known as “Economic Fury” would end if Tehran agrees to a deal, a move that would include opening the critical Strait of Hormuz to all shipping. The warning, delivered via social media, carried a significant threat of escalation, promising that if a deal is not reached, “the bombing will restart” at a “scale and intensity higher than before.”

The statement injects fresh volatility into a tense geopolitical landscape, with U.S. officials offering conflicting assessments of the situation. “If we live in a world where this rogue state like this Iranian regime is allowed to claim as a new normal — control of an international shipping lane — it will not be long before you see that happen in multiple shipping lanes around the world,” Secretary of State Marco Rubio said at a White House press briefing.

The market impact was immediate, with prediction markets showing an increase in pricing for a YES outcome on WTI Crude Oil prices rising in May 2026, suggesting traders are bracing for potential supply disruptions. The Strait of Hormuz is a chokepoint for nearly a fifth of the world's oil supply. The same markets show a decreasing probability of Trump agreeing to Iranian demands for sanction relief, reflecting the high-stakes nature of the ultimatum.

At stake is the stability of global energy prices and the broader economy. Rubio warned of a scenario where a nuclear-armed Iran could close the strait and cause U.S. gas prices to hit “$9 a gallon or $8 a gallon.” The former president's ultimatum creates a binary outcome for markets: a deal could see oil prices fall and risk assets rally, while renewed conflict could trigger a sharp oil spike and a sell-off in global equities on fears of inflation and instability.

The “Economic Fury” Campaign

The ultimatum comes as the U.S. Treasury continues to tighten its financial chokehold on Tehran. The "Economic Fury" campaign has recently focused on Iran's shadow banking networks, with sanctions imposed on three Iranian foreign currency exchange houses. According to the Treasury, these entities are instrumental in laundering oil revenue from China, which helps fund the Iranian Revolutionary Guard Corps and its proxies. While Beijing has instructed its companies not to comply with these unilateral sanctions, the U.S. action underscores a strategy of maximum financial pressure.

Conflicting Signals from Washington

Adding to the uncertainty are contradictory statements from senior U.S. officials. While Secretary Rubio acknowledged Iran's effective control over the strait, Defense Secretary Pete Hegseth insisted otherwise. “Two U.S. commercial ships, along with American destroyers, have already safely transited the strait, showing the lane is clear,” Hegseth said Tuesday. “They said they control the strait. They do not.” Despite this, shipping traffic through the strait remains a fraction of pre-conflict levels, and the United Arab Emirates recently announced its air defenses were engaging a missile threat believed to originate from Iran, highlighting the fragile nature of the current truce.

Observers are now closely watching for any official response from Tehran, further military posturing in the Persian Gulf, and any change in China's willingness to defy U.S. sanctions. The next move from either side could determine the direction of oil prices for the remainder of the year.
