US stock market hits record high amid hopes for Strait of Hormuz reopening
The S&P 500 surged 1.8% past 7,700 for the first time, driven by strong corporate earnings and progress in Iran-Oman talks on reopening the Strait of Hormuz to shipping.

Wall Street's benchmark S&P 500 broke through 7,700 as investors cheered both a robust earnings season, with Palantir jumping 29.5%, and diplomatic progress between Iran and Oman on restoring traffic through the Strait of Hormuz. Brent crude fell 13% in a week on the same hopes.
The US stock market climbed to its highest level ever because investors got excited about two things at once: companies are making lots of money, and grown-ups are talking about reopening a big ocean road for oil ships. When fewer ships can pass, gas costs more, so fixing that traffic jam is good news for everyone who drives a car.
Analysis
A Record Powered by Two Engines
The S&P 500's 1.8% surge past 7,700 was no single-cause event. Two forces converged: a corporate earnings season that continues to deliver upside surprises, and a tentative diplomatic opening on the Strait of Hormuz that pulled the geopolitical risk premium out of energy markets and equities alike. Palantir Technologies exemplified the earnings leg, with its 29.5% one-day pop on second-quarter revenue of $1.94 billion — a defense-adjacent data analytics company riding the same tailwinds that the broader market is now pricing in. The Dow Jones Industrial Average, climbing 1.7% to 54,085.88, confirmed the move with a second consecutive record close.
The Hormuz Thaw and the Oil Discount
The diplomatic channel running through Muscat appears to be doing the heavy lifting. Brent crude futures for October delivery sat at $79.11 a barrel, down roughly 13% week-on-week, reflecting trader bets that the months-long shipping disruption is approaching a resolution. The data underscores how severe the choke had become: just nine vessels transited the strait on Sunday, according to ship-tracking platform MarineTraffic, compared with roughly 130 daily crossings before the US-Israel war on Iran began in late February. Iran's Foreign Ministry spokesperson Esmaeil Baghaei described the Omani-mediated talks as "positive," while Secretary of State Marco Rubio said a deal could happen "very shortly" — language calibrated to move markets without prematurely committing Washington. Treasury Secretary Scott Bessent went further, telling CNBC an agreement could be reached as soon as Tuesday or Wednesday.
The Catch Behind the Rally
The bullish case is not without fault lines. The US military, through Central Command, insists the strait is "free and open" and says forces have assisted more than 1,000 vessel transits in three months, yet Tehran continues to assert control over traffic movement, and the actual transit numbers tell a different story than the rhetoric. Asian markets followed Wall Street higher, with Tokyo's Nikkei 225 up 3% and Seoul's Kospi up 4.6% in early Wednesday trade, suggesting the relief trade is global. Should the Muscat talks stall, or should Iran reinterpret any "safe route" agreement, shipping flow could snap back toward wartime levels — and with it, the energy shock that helped drive inflation fears earlier in the year. For now, equity markets are pricing in a resolution; the geopolitical reality is still being negotiated on the water and at the table.
Key points
- S&P 500 surged 1.8% past 7,700 for the first time, blowing past its prior record of 7,620.90 set on June 2 and up 12.80% year-to-date.
- Palantir Technologies jumped 29.5% after reporting second-quarter revenue of $1.94 billion, beating forecasts.
- The Dow Jones Industrial Average set a record for a second straight day at 54,085.88, while Japan's Nikkei 225 and South Korea's Kospi posted major gains in early Wednesday trade.
- Brent crude fell to $79.11 a barrel, down about 13% week-on-week, as traders bet on a Hormuz reopening.
- Iran-Oman talks are showing "positive" progress, according to Iranian Foreign Ministry spokesperson Esmaeil Baghaei, with US officials expressing hope a deal will be reached imminently.
- Maritime traffic collapsed to just nine vessels on Sunday versus roughly 130 daily crossings before the US-Israel war on Iran began in late February.
If the Oman-mediated talks produce a binding arrangement for safe passage through the Strait of Hormuz, shipping volumes could rebound toward pre-war levels of roughly 130 daily transits, easing the energy-price drag on global growth. A durable deal would also unwind the war-risk premium that has been baked into Brent crude and shipping insurance, reinforcing the disinflationary tailwind the equity rally is already pricing in.
Diplomacy of this kind has collapsed before, and the gap between Washington's claim that the strait is "free and open" and the actual transit count of nine vessels on Sunday suggests the situation remains fragile. If Iran reasserts control over shipping or attacks resume, Brent crude could snap back sharply from $79.11, reigniting the inflation impulse that central banks have been working to suppress.
