Wall Street Hits Records as Iran Deal Hopes Drive Oil Below $100

Hopes for an end to months of disruption in the Persian Gulf sent global markets soaring Wednesday. Oil prices fell sharply below $100 a barrel. Major stock indexes in Europe and Asia set fresh records, while Wall Street futures pointed to new highs for the S&P 500 and Dow. The relief trade mixed with ongoing enthusiasm for artificial intelligence, creating a powerful lift across asset classes.

At the center of the move sits one unresolved question: will reported diplomatic progress between the United States and Iran actually reopen the Strait of Hormuz? The waterway carries one-fifth of global oil supply. Iran blockaded it in late February, triggering a spike in energy prices that rippled into inflation worries worldwide. According to multiple reports citing U.S. officials and a Pakistani mediator, the two sides are nearing a one-page memorandum of understanding. It would establish a framework to end active hostilities, ease transit restrictions and set the stage for deeper nuclear negotiations. Axios first reported the White House expectation of Iranian responses within 48 hours. A Pakistani source separately confirmed elements of the account to Reuters.

President Trump described "great progress" toward a final agreement and said he would pause "Project Freedom" escort operations for stranded ships through the strait for a short period. The U.S. port blockade on Iran remains. Iran's Revolutionary Guards Navy stated that safe transit would resume under new procedures, thanking ship operators for following Iranian rules. These signals accelerated a selloff in oil. Brent crude dropped roughly 8 to 10 percent depending on the precise intraday snapshot, falling below $100 for the first time since late April. West Texas Intermediate followed a similar path. Exact closing levels varied across reporting services and could not be independently verified to the penny in every account. The moves marked the largest one-day percentage decline in a month.

Stock markets responded in kind. Europe's STOXX 600 climbed more than 2 percent. Germany's DAX and France's CAC 40 each rose around 2.7 percent. In Asia, South Korea's Kospi surged 6.6 percent after a holiday, clearing the 7,000 mark for the first time. Samsung Electronics jumped 14.8 percent, pushing its market value above $1 trillion on continued artificial intelligence momentum. MSCI's broadest gauges for world stocks, emerging markets and Asia-Pacific shares outside Japan all reached new highs. On Wall Street, the S&P 500 had closed up 0.8 percent Tuesday at a record. Nasdaq gained 1 percent. Dow futures rose as much as 500 points in overnight trading.

The rally had multiple parents. Separate from the Iran news, Nvidia and Corning announced a multiyear partnership to build three advanced optical manufacturing facilities in North Carolina and Texas. The factories, dedicated to technologies that could replace copper cabling with glass fiber in AI data centers, are expected to create at least 3,000 jobs and expand Corning's U.S. optical capacity tenfold. Nvidia shares rose nearly 3 percent on the news. Corning jumped 14 percent. Both companies framed the deal as foundational for faster, lower-power AI infrastructure. Jensen Huang of Nvidia and Wendell Weeks of Corning issued joint statements emphasizing "Made in America" manufacturing revival.

Bond yields eased as traders lowered expectations for aggressive central bank rate hikes. The 10-year U.S. Treasury yield fell several basis points. The dollar weakened against major peers. Gold, often a safe-haven play, rose nearly 2.5 percent. Analysts offered measured reactions. Michael Brown at Pepperstone called the equity surge a "punchy move" in which markets appeared to be "front-running a positive outcome." Ipek Ozkardeskaya at Swissquote warned that "the probability of disappointment looms," suggesting some gains could reverse. Mark Haefele at UBS noted the shift from recent hawkish rhetoric but observed that yields remained elevated and rate-cut expectations for the Federal Reserve this year stayed near zero.

The conflict context stretches beyond Wednesday's headlines. U.S. and Iranian actions around the strait escalated in tit-for-tat fashion through March and April, according to timelines compiled by BBC and Wikipedia summaries of the 2026 Iran crisis. A Pakistan-brokered ceasefire took effect April 8 but has seen reported violations. Shipping disruptions have damaged or abandoned multiple vessels, with unconfirmed reports of seafarer casualties. U.S. crude inventories fell sharply in the week to May 1, according to American Petroleum Institute data cited by Reuters, as refiners scrambled to offset lost flows. These longer-term pressures explain why even a framework deal generated such immediate market enthusiasm.

Whether the memorandum produces lasting de-escalation or merely a temporary pause remains uncertain. No public confirmation has come directly from U.S. or Iranian leadership beyond Trump's remarks. Previous rounds of talks have stalled. Yet the speed of the market response shows how heavily energy costs now weigh on growth forecasts and monetary policy paths from the Federal Reserve to the Bank of England. For investors, Wednesday delivered a rare alignment of geopolitical relief and technology optimism. The test will come in the days ahead when responses to the proposed framework become public.
