Wall Street rally 2026: Nasdaq +3%, Dow record close

What moved markets on June 15

Wall Street rallied on June 15 as investors reacted to reports of a preliminary agreement between the United States and Iran aimed at ending the Middle East war and reopening the Strait of Hormuz. The main driver was the sharp drop in crude oil prices, which eased inflation concerns and helped risk assets outperform. Stocks opened higher and stayed firm into the close in several updates reported through the day. Technology shares led the move, pushing the Nasdaq to its strongest one-day percentage gain since March 31.

The rally came after a weekend news flow that included a public post by Pakistan’s Prime Minister Shehbaz Sharif stating on X that a “Peace Deal” between the U.S. and Iran had been reached. President Donald Trump later confirmed the news in the reporting cited. Some updates also described the agreement as a framework that would extend a ceasefire for 60 days, while laying the groundwork for further talks on Tehran’s nuclear program.

The headline numbers: Dow, S&P 500, Nasdaq

By one set of closing figures reported for Monday, the Dow Jones Industrial Average rose 468.77 points, or 0.92%, to 51,671.03. The S&P 500 gained 122.83 points, or 1.65%, to 7,554.29. The Nasdaq Composite added 795.10 points, or 3.07%, to 26,683.94.

Across other live updates cited in the same text, index levels and point gains varied by timestamp and source, including intraday records and late-session moves. Still, the consistent message was that all three benchmarks advanced strongly, with the Nasdaq leading.

How the U.S.-Iran agreement narrative evolved

Multiple reports described key representatives from both nations confirming that an accord had been finalized over the weekend. One update said the agreement was expected to be formally signed on Friday during discussions in Switzerland. Another update framed it as an announcement made late Sunday that would extend the ceasefire for 60 days.

At the same time, a separate segment in the text noted that final approval from U.S. President Donald Trump and Iranian leadership was still pending. Taken together, the reporting presented a clear market catalyst: traders priced in lower near-term geopolitical risk around energy shipping lanes, even as some procedural steps were still described as outstanding.

Oil slide, inflation fears ease, and equities respond

The news flow explicitly linked the equity rally to a fall in crude oil prices and a reduction in inflation fears. One bullet point in the provided text said oil prices fell 5%. With the Strait of Hormuz central to global oil flows, the prospect of reopening shipping routes supported expectations of smoother energy supply.

That backdrop helped explain why equities surged quickly after the open and held gains through the session. The tone across updates was that optimism about peace and lower energy costs outweighed other near-term concerns.

Intraday milestones and record highs

The Dow notched record levels in the reports, including a “record-high close” and an “intraday record high.” One update said the Dow climbed by 620 points, or 1.2%, to 51,821, marking its first intraday record since June 5. Another late-session snapshot cited the Dow up about 590 points, or 1.2%, to 51,789.

The Nasdaq was repeatedly highlighted for outperformance, with gains described around 3% in multiple places. The S&P 500 also moved to or near record territory in parts of the reporting, supported by the broader “risk-on” swing.

Other notable movers: SpaceX

SpaceX was singled out as a major stock mover in the text. One line said SpaceX was up 10.3% in its first full trading day, adding $139 billion to its market cap. Elsewhere, the text also referenced SpaceX shares rising 6% and said the market cap crossed $1 trillion. These figures were presented as separate updates, but both pointed to outsized interest in the name during the session.

The Fed meeting and rates in focus

The Federal Reserve’s policy meeting this week was also mentioned as a near-term macro event. The text cited a “98% chance” that the Fed would hold rates steady. With markets already reacting to oil-driven inflation expectations, the Fed backdrop mattered because lower energy prices can influence the inflation narrative that shapes rate expectations.

Global spillovers: Asia cues and India’s Gift Nifty

International markets were described as trading higher on the same theme. Japan’s Nikkei 225 was reported up 0.88% and the Topix up 0.53% in Asian trading. For India, Gift Nifty was reported around 23,881, at a discount of nearly 116 points from the Nifty futures’ previous close, indicating a gap-down start. Another segment referenced Nifty technical levels, stating resistance near 24,300 and support around 23,800.

Key data points at a glance

Why this matters for investors

The session illustrated how quickly geopolitical headlines can feed through to energy prices, inflation expectations, and equity risk appetite. In the reporting provided, the Strait of Hormuz was the central transmission channel: the expectation of reopened shipping routes pushed oil lower, and stocks higher. The Nasdaq’s outperformance also reinforced the market’s tendency to rotate into growth and tech when inflation fears ease.

At the same time, the text included both “accord finalized” language and notes that final approvals were still pending. That contrast mattered because it showed markets responding to the direction of travel in diplomacy, even before every formal step is completed.

What to watch next

The reporting pointed to a formal signing planned for Friday in Switzerland and described a ceasefire extension framework of 60 days. Investors will also track the Fed meeting this week, which was described as likely to result in rates being held steady. For global markets, further updates on shipping through the Strait of Hormuz and any confirmed terms of the U.S.-Iran arrangement remain the next key inputs.
