Dow Hits Record on Iran Deal Optimism as Oil Slides

Oil prices dropped to their lowest levels in three months on Tuesday after the announcement of a U.S.-Iran memorandum aimed at ending hostilities in the Middle East, yet tanker operators expressed caution about immediate passage through the Strait of Hormuz and analysts warned that meaningful relief at the pump could take weeks or longer. The agreement, signed electronically on Sunday and set for a formal ceremony in Geneva on Friday, extends a ceasefire for 60 days and pledges to reopen the vital waterway to commercial shipping without Iranian tolls, according to statements from President Donald Trump and Vice President JD Vance.

Brent crude futures fell 2.7 percent to around 80.91 dollars a barrel, while West Texas Intermediate slipped below 80 dollars, reflecting investor relief mixed with uncertainty over the deal's full terms. Washington and Tehran have offered differing accounts of the obligations involved, leaving questions about sanctions relief and enforcement unresolved ahead of discussions at the G7 summit in France.

Shipping executives at companies like Hapag-Lloyd welcomed the prospect of reduced military risks but stressed that actual transit remains on hold pending clearer assurances. The Strait of Hormuz, through which a significant portion of global oil flows, has seen no immediate resumption of traffic despite Trump's claim that it would be fully open by Friday. This gap between announcement and implementation has tempered optimism that gasoline prices will fall quickly for American drivers already strained by earlier spikes tied to the conflict.

Financial markets showed a more muted response after Monday's record gains, with U.S. stock futures essentially flat as attention shifted to the Federal Reserve's upcoming policy meeting. The Dow Jones Industrial Average closed at an all-time high the previous session on the back of the peace framework, but broader indexes paused amid concerns over persistent inflation, which hit 4.2 percent in May. SpaceX shares continued their post-IPO climb, rising another 5 percent in premarket trading after the company announced a major acquisition.

California Governor Gavin Newsom, meanwhile, publicly stated that the Trump Justice Department has launched an investigation into him, his family, and former staffers, describing the move as clear political retaliation. Newsom's comments come as the administration faces scrutiny over how it intends to enforce provisions of the Iran agreement and manage domestic political opponents. Critics have pointed to the timing as evidence of selective enforcement rather than routine oversight.

The memorandum's details are expected to be released later this week, but tanker industry caution and the absence of immediate shipping activity underscore the distance between diplomatic announcements and tangible economic outcomes. Drivers seeking lower fuel costs will likely wait through the summer before seeing sustained declines, even as oil benchmarks ease from recent highs.
