​Stock Market Today: Dow, S&P 500, Nasdaq Surge as Oil Plunges on Iran De-Escalation Hopes

U.S. stocks came roaring back on Monday, with all three major indexes rising as easing geopolitical tensions helped restore risk appetite. The Dow Jones Industrial Average jumped 1.4%, adding more than 600 points, while the S&P 500 gained 1.1%. The tech-heavy Nasdaq Composite led with a 1.2% advance, snapping recent weakness driven by inflation and rate concerns.

The rally came as markets reacted to a sudden shift in the geopolitical narrative. After a tense weekend that threatened further escalation in the Middle East, investors welcomed news that the US would postpone military strikes on Iran, triggering a steep drop in oil prices and a surge in equities. The move helped soothe inflation fears that had been weighing heavily on stocks in recent sessions.

Market Movers:

• TeraWulf (WULF) +12% – Shares surged alongside the broader crypto sector as Bitcoin rebounded above $71,000, fueled by improving risk sentiment. The rally reflects renewed investor appetite for high-beta assets as geopolitical tensions ease.
• Synopsys (SNPS) +4% – The stock climbed after activist investor Elliott Investment Management disclosed a major stake and signaled plans to push for operational improvements. Investors are betting on margin expansion and stronger positioning within the semiconductor ecosystem.
• Newmont (NEM) +4% – Gold miners rebounded as precious metals stabilized following last week’s sharp sell-off. The move came as easing geopolitical stress reduced forced liquidation pressure across commodities.
• Super Micro Computer (SMCI) -3% – Shares extended losses after last week’s sharp plunge tied to legal issues involving individuals connected to the company. Ongoing governance concerns and potential customer hesitation continue to weigh on sentiment.

Oil Prices Collapse, Fueling Risk-On Rally

The biggest catalyst for Monday’s market surge was a dramatic drop in oil prices. West Texas Intermediate crude plunged more than 8%, while Brent crude also tumbled after President Trump signaled progress in diplomatic talks with Iran and delayed planned strikes on energy infrastructure.

This sharp reversal in oil helped cool immediate inflation fears, which had grown as crude prices previously spiked above $110 per barrel. Lower energy prices reduce pressure on both consumers and businesses, giving markets hope that inflation may not spiral further in the near term. However, analysts caution that volatility remains high. Oil markets are still highly sensitive to headlines, and any renewed disruption to supply could quickly reverse the trend.

Treasury Yields Retreat as Bond Market Stabilizes

Bond markets also reflected the shift in sentiment, with Treasury yields pulling back after last week’s spike. The 10-year yield dropped notably, offering relief to equities, particularly in rate-sensitive sectors like technology. The decline in yields signals that investors are dialing back expectations of prolonged inflation pressure and aggressive monetary policy. Just days ago, rising yields had reflected fears that the Federal Reserve might keep rates higher for longer due to energy-driven inflation. This pullback provided a key tailwind for stocks, as lower yields improve valuations and ease financial conditions.

Policy and Market Structure Back in Focus

Beyond geopolitics, investors are also digesting shifting expectations around Federal Reserve policy. The central bank’s recent messaging has leaned cautious, with officials emphasizing uncertainty around inflation and growth. Meanwhile, developments in Washington are also influencing specific sectors. Reports that lawmakers are preparing new regulations targeting prediction markets sparked gains in traditional sports betting stocks, highlighting how policy shifts continue to reshape competitive dynamics across industries. At the same time, corporate news, from activist investor activity to major tech initiatives, continues to provide stock-specific catalysts in an otherwise macro-driven market.

Looking Ahead

Monday’s rally underscores just how quickly sentiment can shift in today’s market. A single geopolitical headline was enough to send oil prices plunging and stocks surging, reversing the risk-off tone that dominated last week. Looking ahead, investors will remain laser-focused on three key drivers: developments in the Middle East, the trajectory of oil prices, and signals from the Federal Reserve on rate policy.

While the pause in escalation is hopeful, uncertainty remains, and markets are likely to stay volatile. If oil continues to ease and inflation fears subside, equities could find room to stabilize or even extend gains. But with geopolitical risks still simmering and the Fed maintaining a cautious stance, any relief rally may face fresh tests in the days ahead.
