KEY POINTS
- The Dow Jones closed at a record 51,671.03, up 0.92%, while the S&P 500 gained 1.65% and the Nasdaq surged 3.07% on Monday following the U.S.-Iran peace agreement.
- The historic deal to reopen the Strait of Hormuz sent Brent crude plunging over 4% toward $83 per barrel, removing a geopolitical risk premium that had inflated energy costs for months.
- Traders should watch Wednesday's FOMC decision and press conference from new Fed Chair Kevin Warsh for signals on whether the inflation picture has shifted enough to alter the rate path.
The Dow Jones Industrial Average closed at a record 51,671.03 on Monday, adding 468.77 points as Wall Street roared in response to a historic peace agreement between the United States and Iran. The S&P 500 climbed 1.65% to 7,554.29, and the Nasdaq Composite led with a 3.07% pop to 26,683.94, powered by technology heavyweights and the ongoing SpaceX frenzy.
The catalyst was unmistakable. President Donald Trump announced over the weekend that the two nations had reached a framework to end the conflict and reopen the Strait of Hormuz to unrestricted commercial shipping. Iranian Deputy Foreign Minister Kazem Gharibabadi confirmed the text would be released following a signing ceremony in Switzerland, and the deal reportedly includes provisions for dismantling Iran's nuclear program alongside sanctions relief.
Oil Plunges, Risk Appetite Surges
The market's reaction was swift and broad. Brent crude plunged over 4% to $83.75 per barrel, while West Texas Intermediate dropped to $80.87, both touching two-month lows. The collapse in energy prices carried immediate implications for inflation expectations, which had been the dominant headwind for equities since Iran's near-closure of the Strait of Hormuz disrupted roughly one-fifth of global oil shipments starting in late February.
Energy stocks predictably lagged the tape, but nearly every other sector participated in the rally. Technology, consumer discretionary, and industrials led the advance. The breadth was notable — this was not a narrow, megacap-driven move. Advancing issues outnumbered decliners by more than three to one on the NYSE, a sign that institutional money was moving aggressively into risk assets.
The VIX dropped below 14 for the first time since early March, reflecting a rapid repricing of geopolitical risk. Credit spreads tightened in tandem, with investment-grade corporate bond spreads narrowing by 5 basis points on the day. The message from fixed income was consistent with equities: the market is treating this deal as credible and durable.
SpaceX Keeps the Momentum Rolling
Adding fuel to the Nasdaq's outperformance, SpaceX (SPCX) extended its post-IPO tear, closing at $177.99 after trading as high as $179.43. The stock has gained more than 30% from its $135 IPO price in just two sessions, and Bloomberg reported the company briefly crossed a $2.5 trillion market capitalization. Options trading on SPCX is expected to launch this week, which could amplify volatility in both directions.
The broader tech trade also benefited from the oil selloff. Lower energy costs feed directly into margins for data center operators and cloud infrastructure companies, and the AI capex cycle shows no signs of slowing. Nvidia, Microsoft, and Amazon all posted gains north of 2%.
What Comes Next
Tuesday's premarket showed futures drifting flat, with S&P 500 futures up just 0.1% as traders shifted their attention from geopolitics to monetary policy. The Federal Reserve begins its two-day meeting on Tuesday, and Wednesday's announcement will mark Kevin Warsh's first rate decision and press conference as Fed Chair.
The 10-year Treasury yield held steady at 4.48%, suggesting the bond market is not yet convinced that the Iran deal changes the Fed's calculus in a meaningful way. Inflation at 4.2% remains well above target, and the labor market added 172,000 jobs in May. The consensus expectation is for a rate hold at 3.50%-3.75%, but the dot plot and Warsh's tone will matter far more than the decision itself.
For traders, the setup is clear: Monday's rally priced in the geopolitical headline. Sustaining gains above S&P 7,500 requires confirmation that the inflation trajectory has genuinely turned. Wednesday at 2 p.m. Eastern is the next inflection point.
