Stocks Rally, Oil Eases After Report Iran May Reopen Hormuz

Wall Street treated a diplomatic headline as relief, not alarm: stocks advanced and oil pared gains after Iran floated a proposal to reopen the Strait of Hormuz. The reaction underscored a market that is still braced for Middle East brinkmanship, but quick to reward any sign that oil flows and ceasefire talks may hold.

The proposal was conveyed through Pakistani mediators and would postpone nuclear negotiations to a later stage while extending the ceasefire, giving the parties room to work toward a permanent end to the fighting. That was enough to cool a trade that had been built on fear of disruption. Traders have spent weeks repricing every new headline tied to the strait, because even limited interference can change the outlook for crude, shipping costs and inflation in a hurry.

The Strait of Hormuz is one of the world’s most consequential energy chokepoints. The U.S. Energy Information Administration says about 20 million barrels a day flowed through it in 2024, equal to roughly 20% of global petroleum liquids consumption. The International Energy Agency puts the figure at about 20 million barrels a day, or around a quarter of world seaborne oil trade, with about 80% of that volume headed for Asia. Both agencies stress that there are very few alternative routes if the passage is shut, and that lasting disruption would hit oil markets hard.

That is why the market has swung so sharply with each turn in the conflict. Oil jumped on April 23 when fresh escalation signs suggested flows could stay blocked, then eased after the latest proposal pointed to a possible off-ramp. Reuters reporting also said only five ships, including one Iranian oil products tanker, passed through the strait in the previous 24 hours on April 24, a stark reminder of how constrained traffic had become. On another volatile day, June 22, 2025, the S&P 500 rose 1% and WTI fell below $70 after Iran’s retaliatory strikes at a U.S. air base in Qatar were viewed as symbolic rather than a wider escalation.

The latest move rippled well beyond crude. MSCI’s Asia Pacific share benchmark rose 1.5%, its emerging markets index reached a record, Taiwan Semiconductor Manufacturing Co. surged 6% to a record and Nasdaq 100 futures advanced 0.3%. For U.S. consumers, that is the same transmission mechanism that can soften gas prices at the pump and lift retirement accounts at the same time: a credible sign of de-escalation can hit oil first, then flow through to inflation expectations, airline costs and equity valuations.
