US Stock Market Rises: Nasdaq Futures Climb 1.3%, S&P 500 Adds 0.6% Amid Iran Deal Focus

U.S. stock market futures moved higher on June 18, 2026, as investors reacted positively to growing optimism surrounding a potential U.S.-Iran agreement. Nasdaq futures jumped 1.3%, while S&P 500 futures gained 0.6%, signaling a stronger risk appetite across Wall Street. 

At the same time, falling oil prices helped ease inflation concerns and boosted sentiment in technology stocks. With markets balancing geopolitical developments and Federal Reserve policy expectations, investors are closely watching whether this momentum can extend into the broader trading session.

Nasdaq Futures Lead Wall Street Higher After Iran Deal Optimism

Technology Stocks Drive Pre-Market Gains

Nasdaq futures led U.S. markets higher on June 18, 2026. Nasdaq 100 futures climbed about 1.3% to 1.5%, while S&P 500 futures gained roughly 0.6% to 0.8%. Investors returned to growth stocks after signs that tensions in the Middle East may continue to ease.

Technology companies were among the biggest winners. Intel surged more than 8% after announcing a major manufacturing partnership with Apple. NVIDIA, Micron Technology, and Marvell Technology also traded higher before the opening bell.

Why Investors are Returning to Risk Assets?

Investors are focusing on lower energy prices and a better inflation outlook. Falling oil prices can reduce costs for businesses and consumers. That often supports technology and growth stocks, which perform better when inflation pressures ease.

The latest market reaction shows that traders are willing to take on more risk when geopolitical uncertainty declines.

How the U.S.-Iran Agreement Is Influencing Financial Markets?

What Does the Deal Mean for Global Energy Markets?

A key part of the agreement involves extending a ceasefire and improving access through the Strait of Hormuz. This route handles a large share of global oil shipments. Markets viewed the development as a positive sign for future energy supplies.

Oil Prices Fall as Risk Premium Fades

Oil prices dropped nearly 3% on June 18, reaching their lowest levels since early March. Investors expect fewer disruptions to global supply chains if the agreement remains in place. Lower oil prices often help reduce inflation expectations and support stock valuations.

Investor Sentiment Improves Beyond Wall Street

The positive mood was not limited to the United States. Several Gulf markets and international equities also moved higher as investors welcomed the deal. Dubai’s benchmark index gained around 0.8%, while other regional markets posted modest advances.

Federal Reserve Outlook Remains a Key Market Risk

Why are Investors Still Watching the Fed?

Despite the market rally, concerns about interest rates remain. The Federal Reserve kept rates unchanged at 3.50% to 3.75%. However, policymakers signaled that another rate increase remains possible later this year.

We went into yesterday's Fed pricing 20 bps in hikes through the end of the year. We're now at 40 bps. I don't think that's what we'll get. The "dots" are stale because oil prices are falling so fast and Warsh de-emphasized them anyway. The Fed won't hike.https://t.co/a5J4XxWjAb pic.twitter.com/Qx0lRy7PXg

Treasury Yields and Rate Expectations

Markets are adjusting expectations for future policy moves. According to Reuters, traders increased the probability of a September rate hike to roughly 50%, up sharply from the previous day. Higher rates could slow economic activity and limit gains in equities.

Conclusion

The latest rise in Nasdaq and S&P 500 futures shows that investors are responding positively to improving U.S.-Iran relations and lower oil prices. Technology stocks remain the market’s strongest driver, while easing inflation expectations are supporting broader sentiment. 

However, the Federal Reserve remains a major variable. If economic data stays favorable and geopolitical tensions continue to cool, the current rally could gain further momentum in the weeks ahead.
