Key Points
- President Trump established an 8 p.m. ET Tuesday ultimatum for Iran to reopen the Strait of Hormuz or face military action
- Brent crude declined 0.3% while WTI rose marginally in response to escalating tensions
- The administration warned of strikes targeting Iranian infrastructure including bridges and power facilities within a four-hour window
- Tehran pledged retaliatory strikes against Persian Gulf energy assets if attacked
- Trader sentiment appears influenced by multiple previous deadline postponements
Crude markets displayed minimal volatility Tuesday while President Donald Trump’s ultimatum regarding the Strait of Hormuz approached its deadline. The six-week standoff has already triggered significant disruptions in worldwide petroleum supply chains.
The administration established an 8 p.m. Eastern Time Tuesday threshold for Iranian agreement to terms. Trump stated American forces possessed the capability to eliminate “every bridge in Iran by 12 o’clock tomorrow night” should Tehran reject the proposal. Power generation facilities would be “burning, exploding and never to be used again,” according to his remarks.
Despite such rhetoric, crude markets demonstrated restrained movement. Brent crude futures slipped 0.3% to approximately $109.40 per barrel. West Texas Intermediate climbed a modest 0.2% to $112.59. Both major benchmarks remained largely unchanged from Monday’s session.
July delivery contracts for Brent crude temporarily fell beneath the $100 threshold. WTI July contracts traded at $90.43, representing a decline from the previous week’s levels.

Market participants may be exhibiting restraint due to the administration’s track record of adjusting this particular deadline on multiple occasions. Many traders appear skeptical regarding actual enforcement at this juncture.
AJ Bell analyst Dan Coatsworth outlined several potential scenarios. Either Washington or Tehran could yield ground, potentially triggering equity rallies and energy price declines. Alternatively, significant escalation could emerge with broader ramifications across financial sectors.
Coatsworth identified a third scenario—another deadline extension, perpetuating market uncertainty through an additional waiting period.
Tehran’s Warning on Regional Energy Assets
Iranian officials have signaled intentions to target Persian Gulf energy infrastructure in response to any American military strikes. Such countermeasures could further constrict global fuel availability and compound economic pressures worldwide.
Negotiators express limited optimism regarding Iranian compliance with the president’s demands, per Wall Street Journal reporting. The Strait of Hormuz represents a critical chokepoint for global petroleum shipments.
Societe Generale analysts outlined two primary trajectories for markets. The first involves a tenuous ceasefire without ground operations and gradual supply normalization. The second scenario features prolonged conflict with ground forces deployed and permanently elevated energy market risk premiums.
Supply Indicators Point to Tightening Conditions
Evidence suggests traders are already factoring in constrained near-term availability. The WTI prompt spread—measuring the differential between the two closest futures contracts—reached approximately $15.50 per barrel Monday, approaching historic highs.
This movement coincided with international buyers accelerating purchases of American crude. Expectations for domestic supply have grown increasingly tight as the confrontation continues.
Trump commented Monday that diplomatic discussions with Iran were “going well,” while emphasizing repercussions should his deadline pass without agreement.
