Stock Market Impact of U.S.-Iran Tensions: Live Updates and Analysis (2026)

The stock market is on edge as traders navigate the uncertain path of the U.S.-Iran war. A volatile session on Tuesday night left stock futures largely unchanged, but the underlying tension is palpable.

Here's a breakdown of the key developments:

But here's where it gets controversial:

  • Goldman Sachs predicts that the U.S.-Iran war could push inflation substantially higher if it drags on. In a baseline scenario, energy price boosts could raise inflation to 2.7% in May, but it could reach 3% if the oil shock persists.

  • UBS Global Wealth Management, however, maintains a favorable outlook for stocks. They expect only minimal disruption to global energy supplies and believe U.S. equities will produce good gains this year, sticking to their S&P 500 year-end price target of 7,700.

  • After-hours trading saw mixed movements for companies like CrowdStrike Holdings, Ross Stores, and Box. CrowdStrike's underwhelming outlook for Q1 led to a 1% slip in shares, while Box's strong guidance and GitLab's lower-than-expected fiscal 2027 guidance caused respective movements of over 2% and 8%. Ross Stores' beat of Wall Street expectations and dividend increase saw its shares rise by 6%.

And this is the part most people miss:

The impact of geopolitical tensions on the stock market is often complex and multifaceted. While some investors may see opportunities in the market volatility, others might opt for a more cautious approach. It's a delicate balance between risk and reward, and the decisions made now could have long-lasting effects.
