Key Takeaways
- President Trump established an 8 p.m. ET Tuesday ultimatum for Iran to reopen the critical Strait of Hormuz shipping lane
- Brent crude fell 0.3% while WTI saw minimal gains, showing muted market response
- The president warned of strikes on Iranian infrastructure including bridges and energy facilities within hours
- Tehran countered with threats to target Persian Gulf energy installations if attacked
- Traders appear skeptical as this deadline has been postponed multiple times previously
Crude markets demonstrated remarkable restraint Tuesday as traders monitored President Donald Trump’s ultimatum to Iran regarding the Strait of Hormuz reopening. The standoff has now entered its sixth week, already triggering significant disruptions to worldwide oil supply.
The president established an 8 p.m. Eastern Time Tuesday deadline for Tehran to reach an agreement. He warned that American forces could eliminate “every bridge in Iran by 12 o’clock tomorrow night” should Iran refuse to comply. Energy facilities would be “burning, exploding and never to be used again,” according to his statement.
Despite the aggressive rhetoric, oil prices showed minimal volatility. Brent crude contracts declined 0.3% to approximately $109.40 per barrel. West Texas Intermediate climbed a modest 0.2% to $112.59. Both major benchmarks remained relatively unchanged from Monday’s session.
July Brent crude contracts temporarily dropped beneath the $100 per barrel threshold. WTI contracts for July settlement traded at $90.43, representing a decline from the previous week’s levels.

Market participants may be displaying caution because the president has postponed this deadline on numerous occasions. Energy traders potentially doubt whether he will execute the threatened action this time around.
Dan Coatsworth, an analyst at AJ Bell, outlined several potential scenarios. Either Washington or Tehran could retreat, potentially triggering a stock market rally and declining energy costs. Alternatively, a major escalation could occur with broader implications across financial markets.
Coatsworth identified a third scenario — another deadline extension, prolonging the period of market uncertainty.
Tehran’s Counter-Threat to Regional Energy Assets
Iranian officials have indicated they will retaliate against any American military action by striking energy infrastructure throughout the Persian Gulf region. Such a counter-offensive could further constrict global petroleum supplies and intensify economic pressure worldwide.
Negotiators reportedly hold little optimism that Tehran will satisfy Trump’s conditions, based on Wall Street Journal reporting. The Strait of Hormuz represents one of the planet’s most critical petroleum shipping corridors.
Societe Generale’s research team outlined two primary possibilities facing markets. Either a tenuous ceasefire without ground operations and gradual supply normalization, or an extended confrontation involving military deployment and permanently elevated energy market risk.
Supply Constraints Already Emerging in Markets
Market indicators suggest traders are already factoring in tighter immediate-term availability. The WTI prompt spread — measuring the differential between its two nearest-dated futures — reached approximately $15.50 per barrel Monday, approaching record territory.
This movement occurred as international purchasers accelerated acquisitions of American crude. Expectations for US supply availability have grown increasingly tight as the confrontation continues.
The president stated Monday that Iranian negotiations were “going well,” while simultaneously emphasizing the repercussions if no agreement materializes before his deadline.
